Large geomagnetic storm in progress

UPDATE: Check out this amazing time lapse video of Auroras in the north. http://apod.nasa.gov/apod/ap101124.html

Expect some wonderful photos to come in from locations to the north. A large geomagnetic storm is in progress after a 2 year lull in activity. Northern Lights, or Aurora Borealis aren’t actually lights at all. The phenomenon consists of excited particles that appear to dance some 50 miles above the surface of the earth. While we are not expected to be able to view them around the Stateline area, many stunning images are beginning to come in this evening!

Strong southerly flow to bring temps to the 50s

8As we go through the last half of the weekend, our winds will pick up at the surface and aloft which will add 10-15 degrees of warmth as early as tomorrow. Look for thermometers to top out around the 50 degree mark both Sunday and Monday. With things this warm and upper level support, I wouldn’t be surprised if we have a few rumbles of thunder during the afternoon on Monday before a big cooldown for Tuesday. Snow flurries may flutter through the sky on the backside of this storm. The image to the left shows forecast upper level wind direction and speed. Darker colors represent faster winds.

A greater chance for accumulating snow is still in the cards for Friday and Saturday as another system takes a more southerly track, thus putting us in the cold sector of the low. We will continue to monitor this through the beginning of the week.

First accumulating snow of the season on the way

76836_10150131093599167_639419166_7799880_4065233_nThere are two different chances for accumulating snow in the next week to ten days. The first (and lesser) chance will be this upcoming Tuesday when a strong cold front/low pressure system moves through the area. While I believe the precipitation will be winding down too quickly by the time the cold air filters in, last night’s GFS model threw out an accumulation of 4.5″ from its solution. I just don’t buy into that right now, but this is reason enough to monitor the models this weekend nonetheless.

I believe a more significant system is coming next weekend as we’re seeing repeating waves of low pressure in a track from the Gulf of Alaska into the Pacific Northwest. As low pressure develops in Colorado next Thursday, a warm front will set up just to our south which may provide us with some freezing drizzle. As the low ejects out of the Rockies, we’ll need to pay close attention to the track. Models now are taking this from Kansas City to Indianapolis with a moderate level of available moisture. While this doesn’t appear it’ll be a full fledged winter storm, from this vantage point it could easily be enough to get the shovels out of the garage for the first time.

Why does Boone County get tornadoes in the fall and winter?

We just passed by Caledonia this afternoon on the way to Poplar Grove, and saw the damage caused by the most recent tornado. Why does that area seem to get its tornados in the late Fall and early Winter, when most other areas  seem to get their tornados in the Spring and Summer ? The folks we talked to in that area are interested in getting information as well. -George

That is a great question! I believe the location of these tornadoes isn’t as important as when they occurred. It was a totally random event that these tornadoes had paths identical to one another. The fact that they occurred during times of the year that aren’t normally perceived as tornado months is what’s most important. Both tornadoes occurred in moderately strong La Niñas (a cooling of the water in the equatorial regions of the Pacific Ocean). It has only recently been learned (within the past five years) that La Niña winters here are more volatile, in both winter and spring-like storm systems here in the Upper Midwest.

So I guess what I’m trying to say is that while May and June are the top months for tornadoes in Northern Illinois, during La Niña years they are more apt to occur in any month…anywhere. -ES

Shopping Forecast

151093_10150130566814167_639419166_7791754_2009734_nAs Aaron Brackett mentioned this morning, it is expected to be mighty chilly in the morning!

However, you could really put this into perspective as there will be quite a few mornings between now and Christmas where the temperatures will be colder. So, good luck if you’re going out in the morning. We hope you get some really great deals and if you’re near American on East State Street between 5 and 7am, stop by and say hello as we’ll be broadcasting live. -ES

Are the deals really worth it?

19As you are heading out to catch those doorbuster deals, you may want to add a good pair of gloves to the list. As a cold front works through the area this afternoon, skies will clear and temperatures will plummet. Look for mercury levels bottoming out in the lower teens before sunrise.

If the cold temperatures weren’t enough, a brisk northwest wind will add a significant wind chill and make exposed skin feel as if it were around zero outside.

Stay warm brave shoppers!

Dense fog this morning

18As you wake up this morning, things may look a little thick. Overnight temperatures dropped to the dew point in many places, which when combined with light winds, means some foggy travel for this morning. As a cold front makes its way into the area, the foggy conditions will quickly clear out by mid morning followed by much colder temperatures.
