A little snow is on the way for the Northland on Sunday as a vigorous system swings through the area, but with the surface low remaining north of us, this will limit the amount/duration of snow we get late this weekend.
Here’s how the late weekend system looks in the upper levels. Greatest chance for some light snow will occur when the strongest lift passes through the area which shows up as the dips in the solid black lines on the image below.

Up and down temperatures are forecast for next week which results in average temperatures being slightly above normal in northeast Minnesota and northwest Wisconsin. Most persistent cold will be found over western Canada while the most persistent warmth will be found farther south/east from the Northland.

I’m continuing to monitor model trends for mid-month for a snowier/colder weather pattern which may setup across the upper Midwest and Great Lakes.
The overall pattern looks favorable for several winter systems to move out of the Rockies with cold, arctic air pouring south out of western Canada behind these systems while warm air spreads north/east ahead of these systems. Stay tuned!

A small but compact disturbance passed well south of our area today, this system produced about 1 to 3 inches of snow today in parts of southwest and far southern Minnesota (south of the Twin Cities) with reports of 4 to 5 inches of snow in a few spots in northern Iowa.

Outside of a few flurries, the weather tonight looks quiet in our area under partly to mostly cloudy skies, lows will mainly be in the teens with north or west winds 5 to 15 mph.
Partly to mostly cloudy skies Saturday with highs in the 20s to around 30 degrees, winds will be out of the west or southwest 10 to 20 mph.
Low pressure with its warm front and cold front swings through the Northland Saturday night into Sunday. Gusty winds, mild temps and some light accumulating snow will accompany this system as it moves through the area. Highs on Sunday are forecast to be in the 30s, but winds from the west gusting to 35 mph will make it feel a little cooler. Note: Snowfall accumulations on Sunday look to range from one-half inch to 2 inches.
