It has been a relatively quiet and tranquil weather pattern across the Midwest lately, with the exception of a few snow makers. The atmosphere is becoming prime to support a larger winter storm with a benchmark track of widespread 6"+ snowfall. Computer models are now coming into agreement of the idea that an area of low pressure will emerge from the Rocky Mountains on Tuesday and press east or northeast through Wednesday. Right now it is way too early to discuss who sees the accumulating snow. Some models take the low through Chicago and some take it through Minneapolis. The impact on where the snow will fall, based on the track, is profound. Expect snow to pile up 50-100 miles northwest to the track of low pressure. Computer model ensembles are further northwest, but the trend had been further southeast. There is a lot to work out over the next several days, but one thing is becoming more clear...the potential for a long swath of 6"+ of snow is increasingly likely. Nevertheless, it does appear that cold air will filter down behind this system, with below normal temperatures for the entire Midwest by mid-next week.
