Now lets get into more of the discussion based portion of this post...
In the meantime, a winter storm (post going up later on that) will set the stage for extreme cold, straight from the North Pole to come roaring in starting Saturday night. The bulk of the cold air passes through Sunday leading to dropping temperatures across Midwest during the afternoon. The coldest of the days looks to fall on Monday, when wind chills will be at their coldest, see above
Here are the latest numbers off forecast consensus and model data from early this afternoon. Its nothing new to places such as northern Minnesota, but what is new is the fact the cold will run 100s of miles further south. Wind chills will range from -30° to -60°+ during much of the time period of Sunday night through Tuesday morning. Highs will struggle to reach single digits below zero all day on Monday leading to possible records. The all time record high minimum is -11° for Chicago, while we are going with a high of -10°, a new record is certainly in reach! And just look at the wind chill low in Fargo, -65°, serious cold right there!
Here you see a map of 850mb off the Canadian CMC model temps (about a mile above the surface) showing the extent of the cold. For a simple perspective, the bright pink on the map is usually reserved for the north pole and part of Siberia. In fact this is what we call the "Polar Vortex." Usually this feature sits on the North Pole, spins around the globe, traps such cold in Northern Canada and Russia. However, on Monday it is poised to move south into the United States, and dominate our temperatures for a few days, before sizzling away Wednesday and Thursday!
And now....drumroll....the latest maps off the 12z European run:
And now you made it all the way to the lows for Monday morning, The map says it all! Another thing to mention is that these lows are actually "warm" considering the air mass. We are fortunate to have some clouds floating around Monday morning which will act as a blanket for our temperatures. Furthermore, gusty winds will lead to atmospheric mixing which will also help to keep temperatures from plummeting to -40! Nevertheless, much of these numbers are still record lows and should be taken very seriously!
