Smoke From the South

09/08/14

Wind is important not only for the potential spread of flames, but the spread of smoke into neighboring area.

We have large fires like the happy camp complex creating large amounts of smoke.  This weekend, a southerly breeze picked up and it wasn't long before southern Oregon's valleys were full of smoke as well.

When we say that there is going to be a southerly breeze, that means that the wind is coming out of the south and pushing north. Since it is moving from south to north, areas north of active fires become down wind and as a result fill with smoke form the active fires.
   
Now that wind direction is shifting from southerly to northwest... Southern Oregon's valleys will no longer be down wind of the fires and will start to smoke clear out.  However, that's only because the smoke will be pushing down south and east of the active fires filling Siskiyou county with the smoke.

Supermoon & Perseid Meteors Shower

08/07/14

Liz McGiffin

In case you missed the Supermoon last month, don't worry, you'll have another chance to enjoy it this weekend.

A Supermoon occurs when the earth and moon are at their closest distance together.  As a result, the full moon appears to be 14% larger than normal and 30% brighter.

This weekend also leads us into the peak of the annual August  Perseid meteor shower.  It's during the peak that we can watch up to around 100 shooting per hour.  While these shooting stars will still be visible, even with glare of the moon, some experts say though that the number of shooting stars we see this year could be cut in half.  This is because with the Supermoon lighting up the sky, it taking away from the normal sharp contrast of the bright starts against the darkness of night sky.

Even though the peak of this even lasts until the 13th, this is a long lasting shower.  So, if this weekend doesn't work out, don't worry.  The shower continues 2 weeks after its peak, so you still have plenty of time to pick a night that works best for you.

Fire Clouds

08/05/14

Liz McGiffin

Large fires affect more than just the ground that they're traveling on. The flames from fires like the Gulch can actually create their own clouds and weather.

These clouds are called pyrocumulonimbus clouds, or once they become a thunderstorm clouds, a pyrocumulonimbus.

These clouds initially form from, a column of hot air rising into the atmosphere.  Within this column of air, if low level moisture is available, it rises as well.  Once it has been raised high enough in the atmosphere, it follows a normal cloud formation process, cooling and condensing.

These clouds can be extremely dangerous because the rising particles that helped form the cloud can carry an electric charge, resulting in new lightning producing thunderstorms which could spark new fires.  These thunderstorms also produce as strong, gusty winds which will rapidly spread the flames.  And, these clouds produce little to no rain to put these new fires out.

Triple Digit July

07/31/14

Liz McGiffin

There's no doubt about it, this month has been hot.  And it seems like we just haven't been able to shake 100 degree plus temperature days.
   
While the number of days that we hit 100 degrees or higher fluctuates each year, on average, we only see 4 during the month of July in the Medford area. This year we've already tripled that number and are going for day 13.

The average high temperature for this month of July this year was just shy of 97 degrees.  Without counting today, 12 of those days have climbed up to 100 to 106 degrees.

Right now the record for most triple digit days in the month of July is 13.  This was set in 1973, then tied in 1990.  Hitting the century mark today at the Medford airport would not only add 2014 to the list of most triple digit days in the month of July, but keep us on track for the hottest July on record.

Record Heat?

07/28/14

Liz McGiffin
      
There's no doubt about it... The next couple of days are going to be hot!
But will be breaking any records?

Well, in the Medford area, we might have some close calls.  Temperatures will remain right around 100 degrees, but are not on track to reach the current record values, which are between 105-110.  Still, we'll be 5-10 degrees above normal (93 degrees) for this time of the year.

A similar pattern is heading toward Yreka.  High temperatures are going to stay between the upper 90s and lower 100s.  This may not be hot enough to set or tie any record highs, but will still be well above the average temperature for this time of the year, which is 94 degrees.

Supermoon

07/11/14

Liz McGiffin

If you're looking out your window tonight, you might notice that the moon is a little bigger and brighter than usual.  Tonight we're going to experience what is known as a super moon.

This happens when 2 factors align: The first is the moon entering the full moon stage.  The second is perigee, which when the moon's elliptical orbit brings it the closest distance to the earth.

As a result, the moon is going to be hard to miss!

Its appearance will be 14 percent larger than normal, and it's brightness increases by 30 percent.    

If you can't make it out to view the "supermoon" tonight, don't worry, you'll get two more chances this summer.  One on August 10 as well as on September 9.

Heat Advisory

07/07/14

Liz McGiffin

This afternoon Southern Oregon and Northern California went under a heat advisory, but what does that mean?

Well, for starters, you can probably guess based off the name alone that it means we are going to be hot!

The National Weather Service issues heat advisories for areas inland 10 miles or more from the coast when high temperatures are expected to hit 103 or higher for 2 or more days.
Low temperatures are also a factor. During a heat advisory, we won't catch much relief at night since lows will only fall to 65 degrees or higher.

From the coast inland 10 miles, temperatures don't get nearly as hot as they do in the valleys, so the criteria is slightly different for the National Weather Service to issue a heat advisory. 
Low temperatures will still only reach 65 degrees or greater, but it only takes 2 or more consecutive days of high of high temperatures of at least 90 degrees, usually just in areas like Brookings which are strongly influenced by the Chetco effect, to issue the advisory.

And the biggest threat with these hot temperatures is going to be more than just a sunburn.  These advisories go out so you can take precautions like drinking extra water and staying out of the sun to avoid heat related illness like heat exhaustion or heat stroke.

Heat Lightning

07/03/14

Liz McGiffin
      
Some areas that did not get thunderstorms yesterday called in reports of what they thought might be "heat lightning."

What is heat lightning?
Well... It's commonly thought to be a specific type of lightning.  But, in actuality, it's just lightning from a distant thunderstorm that is too far away for us to see the actual cloud to ground flash or hear the thunder.

Our view of this distant thunderstorm is blocked by anything from trees to hills, mountains, or simply the curvature of the earth.  Also, the sound of thunder only travels 10 miles from the flash of lightning.  So, sometimes all we get is the flash of light reflected in the clouds.

What's the Real Temperature?

07/01/14

Liz McGiffin

As we head into the hottest part of the year, you might notice the actual high temperature does not always match what your car or the bank thermometer tells you. 

The thermometers that are in your cars or attached to outside locations may look accurate, but actually give you more of a "feels like" temperature.  During the summer months especially, the temperature can feel much warmer because of factors like exposure to direct sunlight, dark or blacktop surfaces or even a lack of ventilation. 

So, what's the real temperature?  To keep consistency and accuracy, the National Weather Service has established standards for equipment, siting, and exposure.

Here are the guidelines for recording temperature: "the sensor (thermometer for temperature) should be mounted 5 feet +/- 1 foot above the ground. The ground over which the shelter [radiation] is located should be typical of the surrounding area. A level, open clearing is desirable so the thermometers are freely ventilated by air flow. Do not install the sensor on a steep slope or in a sheltered hollow unless it is typical of the area or unless data from that type of site are desired. When possible, the shelter should be no closer than four times the height of any obstruction (tree, fence, building, etc.). The sensor should be at least 100 feet from any paved or concrete surface."

So, even though temperatures may reach extreme levels before you get your air conditioning flowing in your car, the official high for the day will actually come from a shaded, ventilated area that is out in the open so that it won't pick up extra heat from plants of concrete surfaces.

More guidelines for official observations can be found at http://www.nws.noaa.gov/om/coop.




Debris & the Wind

06/04/14

Liz McGiffin

Some of the debris that we've seen along the coast came from a tsunami that hit Japan back in 2011.

Japan is a long way from the United States (there's literally an ocean between us!)... So, how does this happen?

Well, it has everything to do with the change of season.

In the winter months, especially when there are storms, areas of low pressure move in and turn the winds in a counter clockwise pattern.  As a result, we stay under a southerly flow and debris is pushed toward the shore.

In the dry, summer months, we see the opposite.  High pressure moves in and  changes the wind direction to rotate in a clockwise pattern.  This introduces a northwesterly flow and helps push that debris back to sea.



Thunderstorm Hazards

05/07/14

Liz McGiffin

Thunderstorms in the Pacific Northwest create more than just a large boom.

Three of the major threats that we deal with are strong, gusty winds, potential for large hail and of course lightning.

While every thunderstorm may not produce record breaking wind speed, on Columbus Day in 1962 a windstorm wind gusts that passed 100 miles per hour.   The strongest winds were up to our north where peak gusts reached 138 miles per hour before the instrument was damaged, the Corvallis airport reported peak wind speeds of 127 miles per hour, and 104 miles per hour at the Portland airport.  It was breezy in our area as well.  Gusts in Klamath Falls reached 65 mph, and Medford and Lakeview topped out at 58 mile per hour gusts.  These gusts were strong enough to knock down trees, collapse barns and left cities without power for 2-3 weeks.

Large hail is also a threat.  On July 9,1995 a severe thunderstorm moved through north central Oregon producing baseball sized (2.75") hail in.  The storm developed near Redmond, but Hermiston took one of the largest hits as hail damaged nearly every vehicle and left their watermelon crop a complete loss.

Baseball sized hail has also been reported in California.  In 1960, Riverside County set the Southern California record for largest hail as it reached 2.75 inches (beating the previous record set on September 21, 1916 of 2.5 inches).

Another major threat is lightning- especially with dry thunderstorms.  If lightning makes contact with our already dry ground, that's all that will be needed to start a new fire.

Oregon & California Tornadoes

05/06/14

Liz McGiffin

It is day 2 of severe weather preparedness week, and today's topic is tornadoes.

While tornadoes are very uncommon in the Pacific Northwest, they're not completely unheard of.

Most years in Oregon, you can count the number of tornado occurrences on one hand- if you even need that!  Since 2008, across the state, Oregon has only seen 10 tornadoes- one of which occurred last year just north of Roseburg.

Tornadoes are also very rare in California.  Over the past 6 years, there have been 42 reported tornadoes, most of which received the minimum damage rating of EF0.

Since 1950, Oregon has only had reports of a grand total of 105 tornadoes most of which were along the state line with Washington.  California has reported just over 400 tornadoes, most of which were short lived, created minimal damage.  The strongest storms received an EF3 rating and was located in the southeast corner of the state.

Flood Safety

05/05/14

Liz McGiffin

This week is Sever Weather Preparedness week, and the National Weather Service is starting off with flash flood awareness.

Flash flooding is simply caused by thunderstorms and heavy rain.

Flooding is the leading weather-related killer, and most of these deaths could have been avoided by simply being prepared and following some simple safety tips.

You may have heard the slogan, "turn around, don't drown!"  This is the best way to summarize what to do when you come across water on the road.  It is NEVER safe to drive into flood waters. It only takes 6 inches of water to knock an adult off their feet and 18 inches of water to sweep a car away.

In the event of flooding, you need to stay on high ground until the flooding subsides.  Again, remember that it is never safe to try to cross water in a vehicle.

Warm Air, Cold Water

04/30/14

Liz McGiffin

We were off to a very warm start to the day, especially in Brookings, where the Brookings Effect/Chetco Effect kept lows near 70, and temperatures only went up from there.

This makes it sounds like a pretty ideal beach day, right?
That is, unless you wanted to go in the water.

Water temperatures in Brooking were only 51 degrees.  This is cold enough that surfing websites like SwellInfo.com recommend not only a full wetsuit, but boots and gloves as well.

Even in Crescent City, where air temperatures were in the 70s by lunch, it was still just 54 degrees in the water.

So even though temperatures along the coast are feeling pretty good, it's still going to be much more comfortable going for a walk than a swim.

Total Lunar Eclipse

04/14/14

By Liz McGiffin

Tonight, we are going to experience a total lunar eclipse, or what you may have heard people call the "Blood Moon."

We'll start with eclipse basics:
The way a lunar eclipse works is that the night will start like normal- the sun will go down, and the moon will continue orbit around the Earth.  The thing that makes a lunar eclipse different is that during its orbit, the sun, Earth and moon fall in a straight line.  This forces the moon to pass the Earth's shadow.

For us on the West coast, this event starts at 10:20 p.m.  This is when the moon will start to shrink as it falls into Earth's shadow.  The partial eclipse will hit just before 11 p.m.

You'll have to stay up a little later to catch the main event.  The total eclipse will start after midnight, and last until 1:25 in the morning.  It's during this 78 minute period that the moon will be in Earth's shadow, and create a red-brown glow - hence the nickname "Blood Moon."

From 1:25 a.m. until 3:10 a.m., the event will wrap up as the moon comes out of Earth's shadow and becomes full.

Enough Rain Yet?

04/03/14

03/04/14

By Liz McGiffin

We've had several rainy days over the past month... But, has it been enough to make a difference?

Well... Not really.

The new water year started started out strong with over 2 and 3/4 inches of rainfall picked up in September.

But October and January were so dry that we quickly slid below normal.

The past two months has been enough to almost bring us back to an average water amount.

But without help from snow pack this winter, the majority of our area is still facing moderate to extreme drought conditions.

Record Rain!

02/13/14

By Liz McGiffin

Yesterday we picked up more than just a little rainfall.

Record amounts were set in the Medford area at 4 pm when we hit 1.02 inches in the rain gauge out by the airport.

But the rain didn't stop there.

We beat the 1975 record and caught 1.10 inches of new rainfall.

Which is the most we've seen in a single calendar day since Dec 4, 2012, when we had 1.20".

Snow on Mount Ashland?

02/06/14

By Liz McGiffin

Throughout the day, we watched as a light rain and snow showers crossed over the area.

However, places like Mount Ashland were still looking pretty bare, after only receiving 1 inch of new snow overnight.
And base snow is still just at 2-4 inches.

The good news for the skiers is that the moisture headed our way and could drop off as much as a foot to a foot and a half before the weekend.

This won't be enough to get the ski lift up and moving, (we'll need a solid 24-30 inches of wet, heavy snow for that!), but at least it's a start!

Snow and Ice to the North

01/28/14

By Liz McGiffin

Today, while we stayed warning free with just a few sprinkles throughout Southern Oregon & Northern California, our neighbors to the north were sliding in freezing rain. 

Many Central Oregon schools canceled class today because the freezing rain was making roads too slick.  Farther up to our North and west, winter weather advisories are going into effect tonight at 9 pm.

That's because the same push of moisture that will be bringing us that next round of rain showers will be paired with colder temperatures, and dump 5 to 10 inches of snow in the valleys and 10 to 20 inches in the mountains to the north.

For us here in Southern Oregon and Northern California?  Well, it's looking like tomorrow will be almost all rain.

By Liz McGiffin

Friday morning some of us woke up to more than just strong winds.  A 2.8 magnitude earthquake hit 25 miles east of Gold beach at 5:53 am.

In terms of magnitude class, this is just a minor earthquake.  It was enough to pop up on the Richter scale, but was only felt over a limited area.  Light earthquakes like this do not cause damage.  But, is still enough to shaking for a few people to feel it.

Boomerang Fog

01/21/14

By Liz McGiffin

From clear skies to fog... Why does that happen?  Well, here's a quick science lesson:

One of the most important ingredients needed for fog is moisture.

Moisture comes in more forms than just rain. In our case, dew is enough to create fog and freezing fog.

Dew forms when the temperature and dew point are equal.  For example, if the dew point is 35 degrees, once we reach a temperature of 35 degrees, moisture will form.

The inversion over the area means that as we increase elevation, we're going against the norm and also increasing temperature.

Dew point temperatures are always lower than or equal to the actual temperature.  Since the inversion is keeping lower temperatures in the lower elevation, there is more moisture availible at the valley. 

During the afternoon, the sun creates enough heat to break up the clouds.  This decreases the relative humidity, and kills the moisture source fueling the fog.

Once the sun sets, it's a different story.  Without clouds to trap in heat, we experience radiational cooling. This is when all the heat literally radiates up into the atmosphere.  This drops the temperature closer to the dew point, raising the relative humidity and starting the cycle of valley fog all over again.

High Wind Warning

01/10/14

By Liz McGiffin

Along with the rain this weekend, the cold front headed our way is going to be bringing some very strong winds, and even high wind warnings.

Before a warning is issued, it starts as a watch.  The biggest difference between a watch and a warning is the timing.  A watch is issued when a severe weather event is possible and more than 24 hours away from happening.  In the case of a high wind watch, wind speeds are anticipated to reach speeds of at least 40 mph and/or gusts of 58 mph.
What should you do when you hear that your county is under a watch?  Simply make sure that you watch the forecast!  You can do this by tuning into News 10 and be prepared for the watch being upgraded to a warning.

If an event doesn't meet this criteria, but is still strong enough to cause problems, an advisory will be issued instead of a warning.  With a high wind advisory, sustained winds will reach 31-39 mph and/or wind gusts between 45-57 mph.  These wind speeds are enough to potentially cause property damage.  Also, drivers need to start using extra caution on the roads- especially when driving high profile vehicles.

A warning means that a severe weather event is either happening now or that there is strong confidence that the event will happen within the next 24 hours.  In the case of a high wind warning, like we have this weekend for the coast and basin, winds will reach sustained speeds of at least 40 mph and/or gust speeds of 58 mph or more.  These speeds are enough to cause blowing debris, and even cause damage to trees or other property.  Wind will also make travel difficult, especially for those driving a high profile vehicle.

The Driest Year On Record

01/01/14

By Liz McGiffin

The close of 2013 brought new records throughout Southern Oregon and Northern California.  However, one record we were hoping not to beat was for the driest year.

In Klamath Falls, an average year will pick up just short of 20 inches of moisture.  2013 though only brought 5.53 inches.  This number not only put us more than 14 inches below normal, but breaks the previous 1959 record for driest year, when we only saw 6.72 inches.

The entire state of California has been significantly low on moisture.  Mount Shasta City in particular only picked up 10 inches of moisture in 2013.  This is more than 33 inches below average and is enough to break the 1976 record for driest year by 4.21 inches.

Southern Oregon's valleys weren't able to escape the dry conditions either.  In 2013, the Medford area picked just under 9 inches of moisture, which is less than half of the average.  The lack of rainfall was also enough to put 2013 in the record books for the driest year, replacing the 1959 record of only 10.42 inches.

About This Air...

12/26/13

By: Liz McGiffin

All week we've been talking about this air stagnation advisory.  But, what caused it in the first place?  Well, simply put: pollution.  Pollution comes in many forms, but the most common are smoke, dust and industry gasses.

While it isn't common to keep around an air stagnation advisory, the pollutants come from very common places.  This includes car exhaust, industry buildings and burnings.

This brings along the next question: if these pollutants are so common, then why won't they leave?  The reason is high pressure.  High pressure is best know for helping to clear clouds and calming winds.  Weak wind is a problem because no new air is coming in, so all the pollutants are staying put.

White Christmas?

12/24/13

By Liz McGiffin

The vision of Christmas usually comes with snowflakes.  However, it's been a while since we've seen them in the valley.  The last time we've seen snow on Christmas was back in 1998, when there was 1 inch of snow on the ground.

Even though the snow isn't common for Christmas in our area, we have seen some years of extremes.  December 24, 1965, the Klamath Falls area picked up just over 7 inches of snow.  Christmas day has seen less.  1952 holds the record for most snow when 4.2 inches fell.

While Christmas Eve this year in Yreka will be staying dry, 1983 brought a very different story.  December 24, 1983 is when a record breaking 10 inches of snow fell in the Yreka area.  Snowfall on Christmas day is so rare, that the current record for the area is just over 1 inch.

Medford is another area looking to see a dry Christmas.  Accumulating snowfall is rare in the Rogue Valley, but back in 1916, we picked up 3 inches of snow on Christmas Eve.  As far as Christmas day for the Medford area, the most snow we've picked up was .7 inches back in 1965.

Driest Year On Record?

12/20/13

By Liz McGiffin

2013 is on track to be a year for the record books.  However, it's not for a record we were hoping to break.  Right now most of Oregon and California has received less than 75% of their average annual moisture.

The current record in Klamath Falls for the driest year on record was in 1959.  We received 6.72 inches of moisture, when typically we see around 15.  So far, the year 2013 has only brought 5.36 inches since January 1.

Mount Shasta City is another area on track to break a record.  So far in 2013, we've only picked up 10 inches of moisture.  This is several inches behind the 1976 record of 14.21 inches.  On average though, the Mount Shasta City area receives 42.51 inches per year.

Unless the Medford area picks up nearly 1.5 inches of moisture by the end of the year, we will also set a new record.  The current record for the driest year in Medford was in 1959 when we only saw 10.43 inches in the rain gauge.

Record Cold

12/04/13

By Liz McGiffin

Today we saw some very cold temperatures, and even set some new record lows.

While the Yreka area will continue to see some extremely cold weather, it looks like the record low of 9 will stay back in 1917.  Tomorrow, will also be quite cold.  But, not quite record breaking.  The record for lowest high temperature is set to stay back in 1972 when highs only reached 30 degrees.

For Klamath Falls, the record low to beat is -3.  Luckily, it looks like that 1972 record will not be broken.  However, tomorrow, we'll see even colder temperatures and could even be in the running to beat the record lowest high, of 26 degrees, that was set in 1972.

Even the coast is catching below freezing temperatures.  Tonight, lows are anticipated to drop to the mid 20s.  This would beat the record low temperature of 29.  In terms of the lowest high temperature in the Brookings area, it looks like it's going to remain back in 1972.

Medford broke a record low this morning, and is on track to break another tonight.  For tomorrow, even though we are looking at another day with highs in the mid 30s, we should pass the freezing point.  That means that the record of 31 for the lowest high temperature will remain for December 5, 1972.

Poor Air Quality

12/02/13

Poor Air

12/2/13

By Liz McGiffin/KTVL.com

You're probably noticing a big difference between last week's air quality and the clean air out there today.  This has to do with several factors, mostly related to the high pressure that was over the area. 

The stationary area of upper level high pressure created sunshine, sinking air and light winds.  Without anything to circulate air pollutants, they were trapped in the Valley and Basin. 

Another factor was the lack of rain.  When we pushed out that area of high pressure, we not only increased the winds, but rainfall helped to clear pollutants from the air and allowed us to breathe a little easier.

Extreme Halloweens

10/31/13

By Liz McGiffin/KTVL.com

This year shaped up to be a very mild Halloween in the Medford area.  If anything, we were a little on the warm side. 

Mid 60s though weren't quite enough to make the books.  The warmest Halloween afternoon the area has seen was in 1949 when we reached 75 degrees.

And while our overnight lows are going to be on the chilly side, they're still nowhere close to 2002's record coldest Halloween.

One area where trick-or-treaters did get very lucky though is with precip.  We're looking to stay dry in Southern Oregon and Northern California.  That means that we can keep the record wettest Halloween back in 1924.

100 Degrees in September??

09/13/13

By Liz McGiffin/KTVL.com

This past week, we've seen quite the warm up!

Temperatures went from mid 80s last Friday to pushing past those 90s at the beginning of the week, and reached past the the triple digit mark on Tuesday and Wednesday.
Normally in mid September, we're not this hot.  Typically, we see daily high temperatures in the mid 80s.

While these very hot temperatures may not be typical, they're certainly not anything new to the Rogue Valley either.  September 27 currently holds the record for the latest day in the Medford area to reach 100 degrees or more.   Back in 2003, thermometers at the Medford airport climbed all the way up to a high of 102.

Not far behind from this record is one set on October 2.  Back in 1980, Medford did not quite reach that 100 degree mark, but just fell one degree short, picking up a high of a very hot 99 degrees.  This is more than 20 degrees above that normal of 78.

So while 90 and 100 degree days become less typical as we push toward fall, they still are not unheard of.

2012-2013 Water Year

09/06/13

By Liz McGiffin/KTVL.com

August 31 marked the end of the water year.  Instead of starting on January 1 like the calendar year, the water year begins on the first day of September.  During this one year span, there is a running total of the amount of moisture collected.  This moisture can come in the form of rain or melted snow, and is calculated in the final form of liquid water. 

In the Medford area, we picked up the most water during the winter months.  During December in particular, Medford picked up over 5.5 inches of liquid water.

So how did we do this year?  Despite a very dry September and summer, Medford wrapped up the water year only about one inch below average.

However, on the calendar year, Medford only picked up 4.55 inches between January 1- August 31.  This puts us more than 5.5 inches below normal.  But remember: the bulk of the moisture hits Southern Oregon during the winter months, so, there's still plenty of time to try to close that gap.

These Temps... What is Normal?

08/14/13

By Liz McGiffin

After a very hot July, we've seen a pretty cool August.
After getting those showers in last week, temperatures dropped nearly 10 degrees below normal.

In Northern California, Mount Shasta City started off last week with temperatures in the lower 90s (5 degrees above average).  Then after we added in those showers and thunderstorms, temperatures fell 7 degrees below our normal of 86 (79 degrees!).

There was a similar trend in the Basin.  Klamath Falls went from 90 degrees last Tuesday to 75 on Saturday.  This 15 degree temperature swing skipped right over that average temperature of 84 degrees.

Medford saw the same thing.  The average temperature for this time of the year is 92.  Last tuesday we were two degrees shy of 100 on Tuesday.  Then, the clouds and showers rolled in and dropped temperature into the lower 80s (almost 10 degrees below normal!).

So, after spending most of the past week below average, no wonder these more average temperatures feel hot!

Dog Days of Summer

07/06/13

By Krystle Henderson/KTVL.com

The "Dog Days of Summer" are here! You've heard the phrase before but where did it come from? You might be surprised to know the expression actually has little to do with our four-legged friends.

The Romans blamed the extreme summer heat on the star Sirius, which means "scorching." It's the brightest star in the constellation Canis Major which means "big dog." Sirius is close to the sun during July and August, and so when the sweltering heat showed up at the same time, the Romans called it the "Dog Days of Summer," in Latin of course.

These are also the days of the year with the least amount of rainfall in the Northern Hemisphere. The Romans believed the star was responsible for things such as droughts and plagues.

John Brady, author of Clavis Calendaria, wrote in the early 1800s that the Dog Days were a wretched time: "...the Sea boiled, the Wine turned sour, Dogs grew mad, and all other creatures became languid; causing to man, among other diseases, burning fevers, hysterics, and phrensies."

So no need to blame Fido for the hot weather, instead thank your lucky stars!

Heat: A major killer

06/09/13

By Krystle Henderson/KTVL.com

When you think of the deadliest weather, you probably think of hurricanes, earthquakes and tornadoes. Those are all deadly and devastating weather phenomena, but heat tops them all when it comes to fatalities.

Heat is the number one weather-related killer in the United States, causing hundreds of deaths each year. In fact, on average, excessive heat claims more lives each year than floods, lightning, tornadoes and hurricanes combined! And that's an understatement. Many heat-related deaths don't get counted because it's hard to pin-point that heat was the true killer.

Heat-related deaths are difficult to diagnose because there's an absence of standards on what constitutes a heat-related death. There are so many other complicating factors such as a person's health and living conditions.

Some specific examples of disastrous heat waves include the summer of 1980, an estimated 10,000 people died in the central and eastern U.S. In 1995, a heat wave killed about 800 people in the Chicago area. In 2003, a record heat wave in Europe was responsible for about 50,000 deaths.

Evidence of heat-related deaths shows a majority of people who die from heat waves are older males. Studies show, women are more likely to seek help while men try to tough it out. I'm not making a statement, this is statistically speaking!

When it gets hot out there, be sure to check on your neighbors, the elderly, children and bring your pets inside. And I know this seems overdone but please drink plenty of water and make efforts to stay cool!

The deadliest tornado

06/02/13

By Krystle Henderson/KTVL.com

The tornadoes that ripped through the Plains recently seem unreal. What's even more unbelievable is that the area has seen even worse.

The deadliest tornado is U.S. History is known as the Tri-state twister of March 25, 1925. That tornado killed 695 people.

The violent twister was a mile wide and measured up to the highest mark on the Fujita scale. Its track took it through Missouri, Illinois and Indiana, a distance of 219 miles.

Recent research suggests this could have possibly been more than one tornado that developed from a single supercell moving through that area.

Eight other violent tornadoes killed an additional 52 people in Alabama, Tennessee and Kentucky over the course of the day bringing the total killed to 747, also making this the deadliest tornado outbreak in American history.

The deadliest tornado outbreak in the world killed 1,300 people in Bangladesh on April 26, 1989.

About 1,000 tornadoes strike the U.S. every year. Most twisters hit the Plains states in the spring and summer months. Tornadoes also seem to increase in the fall for Dixie Alley, which consists of the Gulf states.

Explosive fire growth possible

05/05/13

By Krystle Henderson/KTVL.com

A Red Flag Warning is now taking grip over portions of northern California because of the potential for explosive fire growth. The warning remains in effect until Monday night.

A system centered over California is kicking up instability in our atmosphere. That along with a moist flow and hot temperatures are creating the threat for thunderstorms.

It's been more than two weeks since we've had measurable rain in our area, so you can only imagine how parched the ground is.

The forecasted lightning and very dry fuels will create the potential for new flames to spark with significant fire growth to both new and old fires.

Some of the storms will be dry, especially east of the Cascades, but will still produce lots of lightning. There's also the threat for gusty outflow winds. Wind gusts up to 40 mph are possible. So if lightning sparks a fire, it can easily take off with the winds fanning the flames. 

The chance for lightning and thunder lasts through the beginning of the workweek.

Check out Saturn from your own backyard!

04/28/13

By Krystle Henderson/KTVL.com

Saturn makes its closest pass near Earth on the night of Sunday April 28, at a distance of only 800 million miles!

Even that far away, experts say it will appear brighter than the stars. You should also be able to see its rings, even with a regular telescope.

To view the ringed planet with your naked eye or through a telescope, you should look halfway up the southern sky at around midnight.

If you check it out, see if you can find the mysterious storm that experts say is brewing on the planet.

If you miss it Sunday night, you can still see it for next couple of weeks as it slowly moves away but it won't be as bright.

Spring has sprung

04/05/13

Wild weather over the last few days and it looks like it will continue through the weekend. Look for occasional clouds, scattered showers, gusty winds and mountain snow at altitudes above 4,500 ft. through Sunday night.
I'll have more information on Your Weather tonight on News10 at 5, 6 and 11pm.
Have a good one!

March wrap-up

04/01/13

By Krystle Henderson/KTVL.com

We wrapped up March with a giant bow! The last day of March brought more rain than almost the entire month put together!

We wound up with 0.56" of rain in the gauge by the end of the month, 0.26" of that fell on March 31. The normal for the month is 1.71".

Not just a dry March but also a dry start to 2013. January, February and March totaled up 2.01" of rain. Normal by now would be 6.15". Compare those numbers to 2012 when we had 8.67" in the rain bucket by this point in the year. In 2011, that total was 7.22" and for 2010, 5.90".

March 2013 was also warmer than normal. The average high temperature was 61.8 degrees, normal is 59.5. If you average the average for the month you get 49.4 degrees, which is 1.1 degrees above the seasonal norm.

The warmest day of the month turned out to be the warmest of the year and Medford's first 80 degree temperature which fell on the 30th of the month. The coldest temperature was an overnight low of 25 on the 23rd.

In March, we got to enjoy more sunny days. There were 13 clear, 12 partly cloudy and six cloudy days.

Check out this comet!

03/10/13

By Krystle Henderson/KTVL.com

The comet PANSTARRS is making its appearance in our skies just after twilight now through mid-to-late March.

Look west just after sunset to catch a glimpse of the comet, which at first will be seen low on the horizon. On March 12, it'll be easy to spot as it makes its way up in the sky near the crescent moon.

NASA says the comet looks somewhat like an exclamation point, with a bright spot and a tail pointing straight up from the horizon.

As each day passes though, the comet will begin to fade away slowly, becoming harder to see without binoculars or telescopes by the end of the month.

PANSTARRS was discovered in June 2011 and was named after the telescopic survey that discovered it: Panoramic Survey Telescope and Rapid Response System.

Scientists estimate the chance to see a comet without a telescope or binoculars happens only once every five to ten years.

Mountain wave pattern

02/24/13

By Krystle Henderson/KTVL.com

Check out this awesome satellite image from this weekend! The clouds are forming what's known as a mountain wave pattern.

What's happening is strong winds aloft are encountering turbulence as they're forced up and over the mountain ridges.

When the air rises it condenses and forms a cloud. The air then sinks leaving an absence of clouds, and then rises again forming another cloud as it moves along.

It keeps going up and down trying to find equilibrium while forming the wavelike effect.

Allergic to the cold

01/20/13

By Krystle Henderson/KTVL.com

If you're like me, you've probably had enough of these cold temperatures already! But cold isn't simply an inconvenience, for some.

Did you know some people are allergic to the cold? Really! It's a condition called cold urticaria.

Researchers still aren't sure how it develops or how widespread it is, but it's real.

Like a typical pollen allergy, doctors say cold urticaria can cause symptoms such as redness, itching, swelling and hives when skin is exposed to the cold.

Another reason for wanting warmer temperatures to come soon!

2012: One rainy year

12/31/12

By Krystle Henderson/KTVL.com

We wrapped up one of the top ten wettest years on record. 2012 is going down in the record books as the 7th wettest year on record with 26.87" of precipitation.

The number six spot is safe for at least another year with 28.62" in the books for the year 1950.

The wettest year on record was 1996 with 31.41" of rain.

Records in Medford go back to the year 1911.

Have a very happy New Year! What records will we break this time around?



New comet could be seen in one year

11/17/12

By Krystle Henderson/KTVL.com

With a clear sky about a year from now, we may be able to see something really spectacular. There's a new comet recently discovered by a couple of Russian astronomers called Comet ISON.

They came up with that name because they were at the International Scientific Optical Network (ISON) where they discovered this comet.

The cool thing about this comet is it's what's called a "sun diver," which means it's going to meet its fiery end as it dives into the gravitational pull of the sun.

The astronomers think it's a brand new comet and one that could produce big tails, possibly even visible in daylight hours.

Again, that will be about a year from now on November 28, 2013. Or it could just fizzle to nothing but we'll be keeping our eye out for it and we will let you know!

Talk about perfect timing! The National Weather Service's annual Winter Weather Awareness Week comes just as we're tracking the first mountain snow of the season.

Sunday October 21 kicks the special week off. During the week, meteorologists will post information about the hazards of winter weather in the Pacific Northwest and give tips on how to protect life and property by preparing and knowing what to do when winter weather strikes.

Our weather ranges from mild to extreme throughout the year. This NWS campaign is an opportunity to refresh locals of the winter weather threats, making sure you're weather-ready for the coming months.

Click here to learn more about how to prepare for snow storms, wind chill, blizzards, ice storms and floods.

Weather Change?

10/08/12

Finally - a change in the weather. Not a huge change mind you - but a change and we'll take anything at this point. Temperatures are coming down over the next few days and we'll see a chance for showers (mostly at the coast) by the end of the week.

Meanwhile - nights remain chilly and even a bit frosty at times. Lows in the Klamath Falls/Lakeview area were in the 25 to 30 degree range over the last several nights. So it's starting to feel a bit more like fall at last.

Try to stay warm - ha!



Naming winter storms

10/06/12

By Krystle Henderson/KTVL.com

Hurricanes get a name, why not major winter storms? Winter storms can strike with similar life-affecting intensity with their own share of disruptive and dangerous effects.

For the upcoming winter season, The Weather Channel will be giving a name to major winter storms. The idea is to better communicate the threat and timing of severe winter weather to the public.

Named tropical storms are instantly recognizable to people. A storm with a name is easier to follow, which will mean fewer surprises and more preparation.

Forecasters will be looking at a number of criteria, such as snow and ice accumulation and that combination of wind which can produce significant impacts.

Naming the winter storms will help differentiate dangerous systems from normal winter weather. In fact, Europe has been doing this for decades.

The Weather Channel calls them names with an attitude because winter has an attitude and can take on a personality of its own.

The names for the 2012-2013 winter season are: Athena, Brutus, Caesar, Draco, Euclid, Freyr, Gandolf, Helen, Iago, Jove, Khan, Luna, Magnus, Nemo, Orko, Plato, Q, Rocky, Saturn, Triton, Ukko, Virgil, Walda, Xerxes, Yogi and Zeus.

Our dry weather

09/29/12

By Krystle Henderson/KTVL.com

Not a drop of rain in Medford since July 20th but how dry is it really?

The graphic below from the National Weather Service shows that, when you take the year so far into account, yes we are drier than normal, which is represented by the red line but not as dry as last year, although we are close.

In 1908, the rain gauge was the driest on record.

Still, the lack of wet weather right now is causing for extreme fire danger to continue to take grip. When the ground is parched and when conditions are ripe to get a fire sparked, flames can spread very quickly.

The color-contoured graphic highlights the dry spots in the Northwest. Southern Oregon and northern California are just covered in deep red colors, which represents little to no rainfall all summer long. And the dry trend is continuing into this first part of fall too.

The bigger picture graphic compares us to the rest of the country. It's all relative, right? Now we don't look so bad. The red bullseye is over the Great Plains, while portions of our region are shaded in yellow and tan, which means abnormally dry to moderate drought.

At this point, we are at more than 70 days and counting without any measurable rain.

Well it's Friday night and that means FOOTBALL! It also means it must be fall. Technically fall begins tomorrow. Yes, that's right - the atumnal equinox is here at last! Just so happens that the official start of fall actually coincides with a bit of a cool down locally. Not much of cool down - to be sure - but at this point I'll take anything that looks 'normal' or 'average' when it comes to the weather.

The leaves are starting to turn - the evenings are cooling off nicely - and it won't be long before we all start complaining about the rain!

New climate change group wants you to join

09/16/12

By Krystle Henderson/KTVL.com

You could say climate change is a hot topic lately. Especially with the drought this summer destroying crops in the Midwest and wildfires scorching the West.

For a few local climate activists, climate change is the reason they're forming a new group called The Rogue Valley Climate Protection Organization.

Brian Ettling, Alan Journet, Susan Bizeau and Jim McGinnis make up the group so far and they want you to join in on the conversation if you're concerned about climate change.

The new group is organizing a climate change meeting on Tuesday, September 25th at 6:30 p.m. in the large community meeting room at the Medford Public Library.

The same climate enthusiasts are organizing a Citizens Climate Lobby Group for the Rogue Valley area and want you to join. An example of the work the group is already doing: they held an international conference call on Saturday, Sept. 8, talking about how climate change is impacting national and local weather.

Group members say that most people are uncertain about climate change and its connection to weather extremes. Members say they want to change that, hoping more people will be apart of the discussion.

Weather Questions...

09/13/12

Hi everybody,

Starting this Friday we'll be answering some of our FaceBook friend's weather questions. This week I'll be answering questions related to the fall/winter season. Hope you'll tune it - it should be interesting. And don't forget to post your questions - after you become a 'friend' of course...

Also starting something new and fun as a volunteer for the Southern Oregon Humane Society. As an animal lover I'm looking forward to doing what I can to help our furry friends - even if it's just taking a lonely dog for a walk in the morning - or playing a bit with some cats.

As for the weather - almost tied a record today in Medford - only 1 degree below the old record of 101 - but we'll be cooling off a bit over the next few days. We'll still be hot and dry - make no mistake. Temperatures in the inland valleys will be a good 10 degrees above average for this time of year - we're talking low 90s - rather than low 80s. So fire danger is still very high - be careful when working and playing in our forests.

Til next time...



Tornado tally

09/09/12

By Krystle Henderson/KTVL.com

A pair of twisters hit the Big Apple Saturday, giving residents there an unusual experience. Tornadoes in New York is a very rare sight. Almost as rare as seeing a twister here in Oregon or California!

The multiple tornadoes touched down in New York on Saturday during a wave of severe weather moving east ahead of a cold front. One of those tornadoes ripped through the Queens borough of New York City. It left plenty of damage, knocking down trees and snapping power lines.

The severe weather was part of the same system that moved through the Midwest overnight, killing four people.  Three of those victims were a girl and her grandparents who died in northeastern Oklahoma, after a fast-moving storm blew their mobile home off its foundation.  

How rare were these twisters? The image below shows the average number of tornadoes per state each year. Oregon has an average number of three, Washington only two, and California and New York are tied with an average of nine. Texas averages nearly twice as many tornadoes on an annual basis than any other state.

Hiatus

09/04/12

Hi everyone. Sorry it's been so long since I've updated this blog. Been a tough few months. Not all bad to be sure -- but tough. Had some health issues -- the bulk of which have been resolved. I'm still recovering and getting a little better every day. Won't bore you all with the details -- I'm going to be all right.

As for the weather -- no complaints -- least not from me. This is perfect as far as I'm concerned. Highs around 80 to 90. Cool nights. Light winds. A bit of smoke to contend with but it's certainly been worse here over the years. This is tolerable. We will be cooling off a bit toward next week but no rain in the forecast for some time to come.

Hope you all stay healthy and happy -- enjoy these 'end of the summer' days to the fullest.



A blue moon isn't really blue

09/01/12

By Krystle Henderson/KTVL.com

If you looked up at the sky Friday night, you probably saw the very special full moon. It's called a blue moon but the name has nothing to do with the color.

The average lunar cycle is about 29.5 days. A blue moon occurs when there is a second full moon in one calendar month. There was a full moon on Aug. 1 and again on Aug. 31, making it a blue moon.

It's pretty rare. It's not going to happen again until July 2015.

The phrase "once in a blue moon" is used to describe something that rarely happens. So if you've ever used that expression to describe something you do, I hope you got it done Aug. 31!

Where does that phrase come from anyway? It goes back to the old English clergy. The date of Easter is determined by the first Sunday after the first full moon after the Spring Equinox. So when there was an extra full moon before lent, it messed up the calendar. The clergy called it the "betrayer moon" and the old English word for betrayer is "belewe" (sounds like "blue").

Triple-digit heat

08/04/12

By Krystle Henderson/KTVL.com

August 4th wasn't only the hottest day of 2012 but also the hottest day in years! Medford hit a high of 107 degrees, which was just one degree shy of tying the record of 108 degrees set back in 1998.

The last time Medford's temperature topped out at 107 was July 23, 2006.

However, Medford has been hotter than that since then. During the summers of 2008 and 2009, Medford saw the mercury in the thermometer reach 108 and even 109 degrees.

The last time Medford hit the century mark was August 25, 2010 at 105 degrees.

The triple-digit heat has been a long time coming. Before we sizzled at 107 degrees on Saturday, we counted up 709 days in a row with temperatures below 100. That's the second longest consecutive days with sub-100 temperatures on record.

The record longest stretch of below 100 degree temperatures is 732 days which ended on July 25, 1958.

Missing: 100 degrees

07/28/12

By Krystle Henderson/KTVL.com

It's been quite some time since Medford hit that century mark. In fact, this is the second longest stretch of sub-100 temperatures on record.

The last time the mercury in the thermometer stacked up to 100+ degrees was Aug. 25, 2010. As of July 28, 2012, that puts us at 703 days without triple digits. The longest stretch was 732 days which ended on July 25, 1958.

If we can make it to Aug. 27 this year without hitting that 100 degree mark, we will break that record.

We still have a chance to hit that magic mark. The latest first time to hit 100 degrees is Sept. 8, a record set back in 1963. The latest to hit 100 in a year (doesn't have to be the first one) is Sept. 27, which had tied records in 1963 and 2003.



Bolt from the blue

07/15/12

By Krystle Henderson/KTVL.com

Lightning can be really exciting to watch but do it from indoors! Lightning is very dangerous. In the United States, an average of 55 people are killed each year by lightning and many more are injured. To date (July 15), there have been nine deaths in 2012.

When you hear me, Kevin or Lindsey warning of thunderstorms in your area or headed your way, it's your best bet to go inside and wait it out.

Here's something you might not know, and I find very interesting... there can be a thunderstorm miles away, that you can't even hear and it can strike you!

It's called "bolt from the blue." It's a cloud-to-ground lightning bolt from a distant thunderstorm, which seems to come right out of the clear blue sky but really, it's coming from the top or edge of a thunderstorm miles away.

According to the National Weather Service, these lightning flashes have been documented to travel more than 25 miles away from the thunderstorm cloud but recent research from lightning detection networks show that lightning can actually travel 60 miles or more!

We all know weather and climate affect our everyday lives but did you know they have such a big impact on Hostess Twinkies that the company has to make two special recipes?

The Hostess Twinkies recipe varies from winter to summer!

Hostess Twinkies actually alters its recipe to account for changes in summer temperatures and humidity.

I thought this was just fascinating! I found out about this in my Applied Climatology course. What a perfect example of how climate affects just about everything!

Summer is coming

06/17/12

By Krystle Henderson/KTVL.com

The summer solstice is just around the corner.

Summer begins on Wednesday June 20, when the sun is the highest it ever gets in the sky. The summer solstice also marks the official beginning of astronomical summer in the Northern Hemisphere.

The summer solstice is when the sun is directly above the Tropic of Cancer. We have the most daylight on the solstice than any other day of the year because this is the farthest north the sun moves in the sky.

Places south of the equator begin their winter on our summer solstice and it is the shortest day of the year for them.

While we call the solstice the official first day of summer, there isn't any laws making the solstices and equinoxes the "official" changes in seasons.

Meteorologists call the hottest three months of the year "summer." Those months are June, July and August. In terms of weather, that makes more sense than mid-June to mid-September.

Soon after June 20, our daylight will get shorter each day until the winter solstice. The first day of winter begins on December 21, when the shortest amount of daylight occurs.

Rare sky show coming up

06/02/12

By Krystle Henderson/KTVL.com

Get ready for a real sky show this Tuesday, June 5th. What you'll see is Venus slowly inching across the face of the sun.

Unless someone comes across the fountain of youth, this will be your only chance to see it! You see, it's a spectacle that won't repeat for another century.

It's a celestial phenomenon dubbed "transit of Venus."

Museums and schools around the world are holding Venus viewing festivities. Even astronauts aboard the International Space Station plan to check it out.

For a chance to see the star sport a fleeting beauty mark, keep your eyes to the sky beginning at 3:09 p.m. Tuesday. But don't stare at the sun!

Venus covers too little of the sun to block the blinding glare. Instead, use some type of protection or a solar filter.

The passing of Venus over the sun will last about seven hours and will be at its best around sunset, that's if all of our clouds clear out by then.

Tuesday's evening forecast looks to be mostly cloudy with a lingering chance for showers.

Let's hope the break in the clouds will be right where we need it to be!

If you do catch a glimpse of the transit of Venus, please e-mail your photos to ktvl@ktvl.com or directly to me at khenderson@ktvl.com. You can also post them to our News10 Facebook page.



Glasses

05/28/12


Optimists say "The glass is half full." - pessimists say "The glass is half empty." - realists say "The glass is always full - unless it's in a vacuum."

How does that relate to the weather? Well, I guess no matter how we feel about it (the weather) it is - what it is...



My 'F' word is frost

05/26/12

By Krystle Henderson/KTVL.com

When I was giving the weather on-air the other day, I realized what I had said when it was too late to acknowledge it. This is going to make you laugh.

So I was talking about how clear skies, calm conditions and cool nights are very conducive to getting frost forming. Only I accidentally said fog. So then I said, "no the other 'F' word, frost."

And I continued with my forecast. Seconds later when I had moved on from the subject of frost I was thinking, oh no I said "'F' word."

Just so you know, I dont swear so it didn't even occur to me.

So just so we're clear, my 'F' word is frost.

No one called in and complained so I figure they got what I meant and were laughing along with me!



The first 90+ degree day of 2012

05/13/12

By Krystle Henderson/KTVL.com

Did you feel the heat? Medford hit its first 90+ degree day for 2012 on Sunday May 13, making it the hottest day so far this year.

Sunday's high temperature of 95 degrees also tied the record high for the day which was set back in 1973.

So is this too early to be talking 90s? On average, Medford typically hits its first 90 degree mark of the year on May 28.

The record for the earliest first 90 degrees of the year was set on April 13, 1947.

The record latest first 90 degree day was on July 4, 1953.



Summer Like Highs

05/08/12


Although it looks like we'll be cooling off for a few days -- to near normal high temps for this time of year -- we will be heating back up again just in time for the weekend. We're talking highs that are in the 85 to 90 degree range -- about 15 to 20 degrees above normal. I wouldn't be surprised if we didn't see the first 90+ temps in the region. Not much chance for rain any time soon either.

Of course warm temps mean increased runoff into our local rivers. That means the water will be high, cold and fast. We've already seen several accidents this spring. So be cautious when you're having fun on the banks of our beautiful waterways. Especially watch the little ones.

Speaking of little ones -- our little furry friends need your help as well. If your pets are outside a lot during this hot time of the year always make sure they have plenty of water and a shady spot to curl up under. And for goodness sake -- never leave them in the car alone. The temperature inside the vehicle can rise very, very quickly. We're talking as high as 130 degrees. Even if you think you'll just be in and out -- don't do it -- you never know how long the line will be -- or wether or not there will be some problem or delay that slows you down. Your beloved pet's life isn't worth it.

Cheers,



The rest of spring

05/05/12

By Krystle Henderson/KTVL.com

It's time to start thinking about the rest of our spring.

The May outlook from the National Weather Service is calling for cooler temps, a little bit, but drier than normal.

In June and July, temperatures have a better chance of being normal which would be spectacular, not too hot and drier than normal.

Typically May would only have about eight wet days with a monthly total of 1.31 inches; June with five rainy days and a total of 0.62 inches; and July with only two days of rain, usually in the form of thunderstorms that typically would ring out just over a quarter of an inch of rain for the whole month.

So we'll see if we're close to those numbers or lower as predicted.



Spring Weather

05/04/12


Unsettled spring weather continues this week with more clouds, wind and rain through Friday. The good news is that our streak of good weather over the weekend looks to last through this coming weekend with more sunshine and warmer temperatures just in time to get outside and enjoy it. Although it won't be quite as warm as last weekend - it'll still be pretty nice with highs approaching the 65 to 70 degree range -- which is about average for this time of year.

Meanwhile the combination of wet weather followed by sunshine and warmth seems to have created an explosion of pollen. Everyone I know with allergies is complaining about one of the worst springs they've ever experienced in terms of allergic reactions. Sigh. Seems we can't win. Either it's too cold and wet -- too hot and dry -- or your nose is running, your eyes are watering and you sneeze so much you can't relax and enjoy either kind of weather.

Come on summer!



You know it's spring... When your head explodes...

05/04/12

Mine's been exploding every few hours. It's alergy season. Every time I sneeze I think my head's gonna fly off my shoulders. Dog's actually run away a few feet and turn back to look over their shoulder every time I go "Ahh... (dog's begin running here) Ahh... (dog's turn to look at safe distance here) AHH CHOOOOOOO" (then give disaproving look here). Either they're afraid of the sound - or just smart enough to dodge flying spittle. Anyway, I've read that our area is the second highest in the NW for pollen counts. First place goes to the Willamette Valley. Not sure I buy it.

Super moon tomorrow night - plus a meteor shower. Sounds way cooler than it probably is - but what the heck - go out and take a look. The better sky show is May 20th. Solar eclipse. Some of the best views will be from right here in the Southern Oregon, Northern California area. More details on that later.

ACHOO!



You know it's spring... when you want to shave your dog.

05/01/12

We have a mutt. Named her Angel. Got her from the Josephine County Animal Shelter when she was just a few months old. Best dog I've ever had. Smartest, sweetest, cutest pup ever - as far as I'm concerned anyway. But, boy does she shed. I could probably knit a sweater every couple of days just with the hair off our floors. Throw in the hair off the couch - the hair off our bed - the hair off MY CLOTHES and I could knit sweaters for an army - weekly. No lie. It's amazing. The hair seems to be magnetized somehow. It attaches itself to everything -- the way starving leeches from a muddy, southern bog latch onto any passing critter. And once attached - good luck gettin' 'em off. Angel's hair laughs at lint rollers - mocks tape wrapped around your fingers. I think if I had a platoon of chimps - picking her hair off my clothes in 'round the clock shifts - I might look presentable on the air. Might. Since I don't have chimps I'm stuck with the thought of shaving her bald - or asking you all to live with a little dog hair on my suits as I present the weather forecast each night. Spring? I call it 'Shedding Season'.



Oh yah, 80+ degrees!

04/22/12

By Krystle Henderson/KTVL.com

We hit that 80 degree mark for the first time this year on Friday April 20, which is right on cue because we would typically expect to hit 80 by about April 19.

So now for 90 degrees. Medford came awfully close to hitting 90 on Sunday with a high temperature of 89 degrees, which shattered the old record for the day of 84 degrees set back in 1987.

We don't typically expect to make it all the way up to 90 degrees until May 28. However, the record earliest to hit 90 is April 13, set back in 1947. The record latest is July 4, set back in 1953.

So, how do you know when Easter is? Yes, you can always look at a calendar. And yes, it always falls on a Sunday but it's a different date every year, sometimes it lands in March or in April.

Here's a fun fact you can share with your friends and family at the dinner table this Easter: Easter is the first Sunday after the first full moon after the vernal equinox (first day of spring/March 21). So, Easter can never occur before March 22 or later than April 25.

The following are dates of Easter from 1980 to 2024:

1980 April 6         1995 April 16       2010 April 4

1981 April 19       1996 April 7         2011 April 24

'UNSURVIVABLE!' New severe weather warnings aim to scare

04/07/12

By Krystle Henderson/KTVL.com

We don't have to worry about tornadoes around here but interestingly enough, some weather service offices in Missouri and Kansas will start to use words such as "unsurvivable," "catastrophic" and "mass devastation" when forecasters warn for severe storms, such as those that spawn tornadoes.

Here's the story that came down on our wires about the new warnings:

KANSAS CITY, Mo. (AP) - Even expert storm chasers would have struggled to decipher the difference between the tornado warnings sent last May before severe weather hit Joplin and, a few days later, headed again toward downtown Kansas City.

The first tornado was a massive EF-5 twister that killed 161 people as it wiped out a huge chunk of the southwest Missouri community. The second storm caused only minor damage when two weak tornadoes struck in the Kansas City suburbs.

In both cases, the warnings were harbingers of touchdowns. But three out of every four times the National Weather Service issues a formal tornado warning, there isn't one. The result is a "cry wolf" phenomenon that's dulled the effectiveness of tornado warnings, and one the weather service hopes to solve with what amounts to a scare tactic.

In a test that starts Monday, five weather service offices in Kansas and Missouri will use words such as "mass devastation," "unsurvivable" and "catastrophic" in a new kind of warning that's based on the severity of a storm's expected impact. The goal is to more effectively communicate the dangers of an approaching storm so people understand the risks they're about to face.

"We'd like to think that as soon as we say there is a tornado warning, everyone would run to the basement," said Ken Harding, a weather service official in Kansas City. "That's not how it is. They will channel flip, look out the window or call neighbors. A lot of times people don't react until they see it."

The system being tested will create two tiers of warnings for thunderstorms and three tiers for tornadoes, each based on severity. A research team in North Carolina will analyze the results of the experiment, which runs through late fall, and help the weather service decide whether to expand the new warnings to other parts of the country.

Laura Myer, a social science research professor at Mississippi State University, said people she has interviewed want more advance warning about a potential tornado strike and more information on the specific locations where the storms are expected to hit.

"We have found in Mississippi and Alabama and various other Southern states that people feel they would constantly be going to a shelter if they heeded every tornado warning," she said. "For people in mobile homes, that's the craziest thing.

"To get to a shelter, they have to leave home," she said. "They feel like if they left during every watch or warning, they would be on the road all the time."

The primary audiences for weather service's written bulletins are broadcasters who issue warnings on the air and emergency management agencies that activate sirens and respond to the storm's aftermath. In the event of a Joplin-like tornado, the new-look warning would have an urgency hard to ignore.

Andy Bailey, a meteorologist with the National Weather Service office in Pleasant Hill, Mo., said it might look something like this: "THIS IS AN EXTREMELY DANGEROUS TORNADO WITH COMPLETE DEVASTATION LIKELY. ... SEEK SHELTER NOW! ... MOBILE HOMES AND OUTBUILDINGS WILL OFFER NO SHELTER FROM THIS TORNADO -- ABANDON THEM IMMEDIATELY."

Had such a warning come across his television set on May 22, Joplin resident Jeff Lehr said he might have sought shelter. Instead, it wasn't until a siren distracted him from a sporting event he was watching on TV that he looked out a window and saw what appeared to be dark thunderstorm clouds. Even then, he didn't take cover until the windows began imploding in his apartment.

"After hundreds of times of similar thunderstorms approaching Joplin, many of those with tornado warnings attached, and you see them pass ... after all those storms, you kind of get jaundiced about the warnings and tend not to give them the weight you probably should give them," said Lehr, a reporter at The Joplin Globe.

James Spann, chief meteorologist with WBMA-TV in Birmingham, Ala., said the impact-based warning experiment could provide broadcasters and emergency management agencies with a useful tool in an age when a majority of people still wait for an outdated technology -- tornado sirens -- to seek shelter.

He blames the siren mentality and high number of false alarms for the complacency of people living in tornado-prone areas such as Alabama, where 252 people were killed last April 27 in a tornado outbreak that struck communities across the South.

"A lot of politicians and people who don't understand tornadoes try to jump into this," Spann said. "Their first reaction is, 'We've got to get more sirens.' What are these people thinking? They clearly do not understand the issue."

Weird rain

03/26/12

By Krystle Henderson/KTVL.com

With all the rain in the forecast, I'm sure at some point you're going to hear someone say, "it's raining cats and dogs." When we say that, we don't expect to look outside and actually see it raining animals.
 As far as we know anyway, there hasn't ever been reports of cats and dogs falling from the sky but what if I told you there has been reports of it raining animals?  
For more than a century, people have reported weird rain which included frogs, toads, fish or turtles.
In 1873, the Scientific American described a shower of frogs that darkened the sky and fell to the ground during a storm in Missouri.
In 1901, people in Minnesota saw a huge green mass falling out of the sky. They said it made a sound as if lumps of mud were plopping to the ground. When the storm cleared out, they saw a pile of hundreds of frogs and toads covering blocks.
 Many other animals have also been reported, falling like rain from a storm. Different kinds of fish have fallen on priests in Australia, golfers in England and families in Singapore. According to witnesses, even frozen birds and turtles have dropped to the earth like hailstones.
 So how is this weird rain possible? Scientists say the most logical explanation for this strange precipitation is that a violent, strong storm picks up the animals from shallow ponds and creeks and pulls them up into the air. The whirlwinds then carry the animals for miles before dropping them like rain. They compare it to huge dust storms that constantly pick up and drop debris from the sky.
Whether the explanation is true or not, let's just hope we don't start predicting animal showers for tomorrow's forecast!

Fire Weather

unset

Liz McGiffin

NOAA 's National Weather Service continues the Pacific Northwest severe weather awareness week today with fire weather:

It might be hard to start thinking about preparing for fire season, while we're talking about rain showers in the forecast, but summer in the northwest means the beginning of fire season.

Fire weather season reaches its peak in early July and spreads into August and early September.

While wildfires may not be a direct weather phemonanon, the weather does play a major role in the potential start and spread of the flames.  Weather related fires start with dry conditions on the ground, or even a drought like we have now.  The dryness acts like tinder that can quickly start a fire.  Before a fire can expand, it needs a spark.  This spark can come from a number of things, including lightning from a dry summer thunderstorm.

The weather is also the primary cause of rapid wildfire expansion.  Strong, gusty winds usually accompany thunderstorms.  These can vary in direction and push the flames along the area that it is blowing.  This puts not only dry plans at risk, but firefighters too. 

While lightning strikes from dry thunderstorms spark a number of fires in the Northwest, there are several things that we can do to help prevent fires as well.  Most of these revolve around simply not being careless.  It only takes one spark from a campfire that wasn't put out properly, ATV exhaust, a cigarette dropped on the ground or flicked out the window, or even your chimney to create the one spark needed to start a fire.

Tornado?! This Isn't the Midwest!

06/14/13

By Meteorologist Liz McGiffin

Yesterday, a very rare event occurred to our north.  A tornado touched down in McMinnville, Oregon, a city just 35 Miles southwest of Portland.

The intensity of a tornado is determined by the Enhanced Fujita scale scale.  This ranks the storm between EF0 to EF5 based on wind speeds.

In our case, a preliminary survey from the National Weather Service in Portland
concluded that the damage done likely fell into the category of EF0 and EF1 damage.

The lowest classification for a tornado is EF0.  This means that wind speeds are estimated to have reached around highway speeds: between 65-85 mph.

One step above that is EF1.  This means winds between 86-110 mph.

While the United States leads the poles as the country that sees the most tornadoes annually,
Oregon has the 9th lowest tornado count in the country.  Oregon also ranks in the bottom 2 for tornado desnity (per 10,000 square miles).

While it's rare to see a tornado in the state, it's not completely unheard of.  Data collected between 1953-2011 showed that the Beaver state has seen at least 102 tornadoes.  Most of these tornadoes maintained an EF1 or EF0 rating, so nowhere near the devastation caused by EF5s in states like Oklahoma.

So while we may not be seeing damage as bad as the Midwest, we still average 1-2 tornadoes a year.
