A significant pattern change is heading towards the SkyWarn 13 viewing area this weekend. Temperatures in Alaska are starting to “warm up”, therefore the arctic air has two choices. #1 The arctic air crosses over the North Pole and goes into Europe and Russia, which was the case earlier this year, and most of last year. #2 The arctic air tracks towards the lower 48, and moves into the Chippewa Valley. The jet stream will also buckle, and allow this arctic pool of air to head south. The arctic front will pass through early Sunday morning, and the air mass that will be moving in, is coming from northern Canada. Wind chill values and air temperatures will be falling throughout Sunday and into Monday. Afternoon high temps will struggle to rise above zero on Monday and Tuesday. Wind chill values will be between -20 to -30 on Monday and Tuesday morning.

Lets put this arctic air into perspective, and why you will never hear me say ‘extreme cold air’ or try to scare people. If you remember Jimmy Kimmell showed clips of Los Angeles overreacting to cold temperatures last week. The local weather person told people to “cuddle with your dogs to stay warm”, the current temperature was 48 degrees. Regions of Alaska had to deal with temps between -50 to -60 in December.

The record low in Eau Claire for the 21st is -29 in 1984, and in 1970 the afternoon high was only -5. The coldest morning in the Chippewa Valley will be on Tuesday or Wednesday as the weather models are still changing, the forecast will also change. The record low for the 23rd is -32 in 1963, and in 1936 the afternoon high was only -14. Overnight low temperatures next week will likely be colder than last year. In 2012 the coldest morning was only -14. Last winter was a joke, and some pay back is on the way. I almost feel silly for writing tips to say warm, but I will give it a try. #1 Dress in layers. #2 Try to limit your time outdoors. #3 Keep a winter survival kit in your car if you have travel plans. #4 Make sure animals have fresh food and water. #5 Use common sense.
