The most persistent snowfall and heaviest snowfall rates favor western Minnesota. The latest midday Friday forecast models forecast a zone of a few inches of snow across western Minnesota. That’s a bit higher than the forecast earlier Friday.

NOAA’s HRRR model and others crank out a zone of 3 to 6 inches in western Minnesota, with a lighter band of a coating to around 2 inches running into and just north of the Twin Cities.
