Winter storm which will impact southern Minnesota and central/southern Wisconsin on Sunday is currently over the Northern Rockies this afternoon and is moving to the east/southeast per Goes-16 water vapor imagery.
A strong temperature gradient is in place for Sunday’s storm with cold, arctic air over Ontario while warmer air lifts north out of the Central Plains.
Sunday’s storm will be a quick hitter, but snow will fall heavily for roughly 6 hours with potential for 1 to 2 inch per hour snowfall rates across southern Minnesota
Radar forecast below is valid from 6 PM this evening to 6 PM Sunday. Snow spreads into southwest Minnesota later this evening, then across all of southern Minnesota early Sunday morning. Snow is forecast to end Sunday afternoon from west to east.

High temperature forecast for Sunday, February 9th, 2020.
Arctic blast is possible late next week, ~February 13 and 14, but similar to past arctic air masses this winter, this one also looks brief, only sticking around 2 days before moving away next weekend the way it looks now.

Will have mostly cloudy to partly cloudy skies in the Northland tonight and Sunday with some flurries or light snow showers possible at times. Only light snowfall accumulations are expected on Sunday, and that should be confined to far southern areas from Hinckley to Ashland and points south.
Lows tonight will be in the single digits below zero to lower teens above zero. Highs on Sunday will be in the mid teens to mid 20s. Winds out of the southwest tonight will become north on Sunday at 10 to 20 mph.
A few minor snow events could affect the Northland next week, one in the Monday-early Tuesday time frame, the other on Wednesday. Behind that midweek system will be a shot of bitter cold air, and this air mass could push far enough south to affect the Northland late next week with potential for subzero daytime highs, and overnight lows in the teens, 20s and 30s below zero. Note: Dangerously cold wind chills are also possible late next week. Stay tuned.
Computer models do show a rather significant warm-up taking place later this month, beginning ~February 19th, this will be something to watch going forward to see if models continue to show this, or do they back away from it?
