A powerful winter storm is impacting the Northern Plains and Upper Midwest today.
Strong area of low pressure ~988mb was over northeast Nebraska at 3 PM today, this low along with its upper level low will track east to near Chicago, Illinois by Noon Sunday.
The dry slot over southwest Minnesota this afternoon won’t move much more to the north due to the surface low tracking east which will force the dry slot back to the south tonight.
Strong lift and moisture advection is occurring NE of the low this afternoon which is causing bands of heavy snow and or mixed precipitation and even some thunderstorms to develop this afternoon in parts of Wisconsin back into eastern, central and western Minnesota.
Trowal/backside snow affecting parts of the Dakotas today on the NW side of the low.
