The next storm system is already making its way onshore the west coast and is poised to strike the Midwest with a decent amount of snow over a 12-16 hour time period. The snow may be heavy at times as this storm system is efficient enough to wrap around gulf moisture into a below freezing air mass. The system will continue to push east and drop a general 3-6" in the heaviest areas. Computer models differ on the amounts, being a couple days out. Stay tuned for any possible tweaks to the snow forecast.
On the right you see images of a radar simulation ran off the 12z NAM computer model. Most areas will see the snow during the morning hours. This will make for a dicey commute for cities such as Minneapolis and Madison. The snow should push out by the late afternoon. Also notice the darker greens embedded in the wide snow band.
