One-Two Punch For Northern Plains

The Northern Plains/Upper Midwest had been persistently cold the last couple of weeks until a change in the pattern finally warmed things up a bit over the last 2-3 days. An arctic boundary moved through and temperatures tonight are expected to plummet to near zero here in MSP and well below zero further north. The big story, however, is what the models are churning out for Sunday into Tuesday. An area of low pressure that’s currently over the Aleutian Islands will finally shift into the Pacific Northwest Saturday afternoon then continue eastward over the Northern Plains on Sunday. The main track of snow associated with this system will be over ND and into Northern MN and current model guidance is churning out 6-12″ with it. A second system looks to affect the region Sunday night through Monday, but with it still 72-96 hours out, the confidence on this system has been less than stellar, with the main swath happening anywhere from IA/Southern WI to SD/Northern MN. Another 6-10″ looks possible from this second system, but it remains to be seen who will get the bulls-eye from this activity.
