Watch News 12 Today at 5, 6, & 10 p.m. for the latest on the cold air and our next chance of snow!
Thank you for stopping by the Weather Watch 12 blog! This week’s blog entries will be full of lots of new information that many of you probably have never heard about. Tomorrow’s(Wednesday) blog will be in introduction to a weather theory that I learned about while working in Kansas City and had a chance to see in action for 3 years. This theory cycles in the weather and how they can be used for long range forecasting. It should be a very informative entry and one that should create lots of questions.
One week ago today we were getting ready for a very big storm! This storm brought as much as 18″ of snow to southern Wisconsin, but very little to locations along Lake Michigan in Milwaukee. That one storm put a large blanket of snow across the nation’s mid-section which is now helping to reinforce each cold punch of arctic air. One of those spells of cold is upong us right now.
Here is a map of the snow cover across the Northern Hemisphere.
As long as this huge snow pack continues to exist we will continue to see each cold punch have a bite. Think of snow cover as ice cubes in a glass of water, the ice cools the drink, or in this case the ice(snow) the atmosphere.
With the snow on the ground tonight and an arctic airmass over head our lows should drop into the single digits above and below zero inland, with single digits near the lake.
Somtimes models have a hard time with lows when snow is on the ground, so the map below is the NAM forecast temperatures for Wednesday morning. I think temperatures will be a little cooler than this.
That’s it for today, make sure to check back on Wednesday to find out more about the weather pattern theory known as the LRC!
Have a great day and tune into News 12 for the very latest on the forecast!
