Winter storm warnings continue through early Monday for a large portion of Minnesota, the eastern Dakotas and northwest Wisconsin.
Snowfall totals from this storm system will range from 2 to 4 inches in the southeast metro from Farmington to Hastings, while the far west and northwest suburbs could will get 8 inches. And some areas could see double digit accumulations by Monday morning.
6 p.m. CST Saturday surface pressure pattern and temperatures from the RAP model:
The low pressure has yet to tighten its circulation but precipitation was beginning to expand into southwest Minnesota. Screen capture 930 p.m. CST radar:
As the low tracks through northern Iowa on Sunday a band of heavy snow, with perhaps some thunder, is likely to dump 6 to 12 inches from Alexandria through Brainerd to Duluth.
NAM output of six-hourly precipitation ending at 6 p.m. CST Sunday paints considerable liquid water equivalent of snow north of the Metro. Snow to water ratio of 10 to 1 would be on the order of 6 to 8 inches of snow. I expect that as much as 6 inches of snow could fall prior to noon from Alexandria to Little Falls.

Accumulating snow will make for hazardous travel across much of Minnesota and the eastern Dakotas on Sunday. Listen for updates before taking to the highway.
Strong northwest winds kick in on Sunday night and last into Monday morning. Blowing and drifting snow will reduce visibilities to below a quarter mile in rural areas of western and south central Minnesota.
