Here's the snow depth map for Minnesota as of Thursday, February 23, 2017.  Note:  The snow depth map updates only once a week on Thursdays so it doesn't show the new snow that fell last night and today over far southern Minnesota, generally near and south of that dotted yellow line on the map.  Source:

A lot of thunderstorm activity since Thursday evening as a strong area of low pressure heads toward the southern Great Lakes this evening.  Some of the thunderstorms that occurred last night in parts of Nebraska, Iowa, far southern Minnesota and the southern half of Wisconsin were accompanied by heavy snow, sleet or freezing rain.  Source:

Weather Synopsis for northeast Minnesota and northwest Wisconsin

There was a strong area of low pressure located well to the southeast of the Northland late this afternoon.  At 4 PM the surface low of 998mb was over southern Lake Michigan.  This system brought a substantial amount of snow and wind to parts of southern Minnesota and central Wisconsin last night and today while generally light to moderate snow affected parts of northern Wisconsin.

It was a colder day throughout the Northland especially considering how warm it has been lately.  Highs today were in the upper teens to mid 20s with a gusty northerly wind at 10 to 20 mph with gusts to 30 mph.

Low pressure over southern Lake Michigan late this afternoon will track northeast to northern Lake Huron by dawn -- Snow will continue to fall tonight in the southeast portion of northwest Wisconsin, generally along and east of a line from Shell Lake to Ashland with the heavier snowfall further southeast from around Winter and Mellen toward Gile, and south toward Park Falls and Phillips.  The snow is expected to diminish after midnight except along the South Shore where lake effect snow showers should persist overnight.  Elsewhere across the Northland we're looking at partly to mostly cloudy skies for tonight.

A mix of sun and clouds for Saturday with a chance for lake effect snow showers along the South Shore of Lake Superior as winds will be out of the north or northwest until later in the day.

Low temperatures tonight will be in the single digits and teens with subzero lows possible in far northern Minnesota.  Highs Saturday will mainly be in the 20s.

A dusting of snow remains possible late Saturday night into Sunday morning as a weak system and cold front pass through the area.

Forecast for Duluth and Superior

.Tonight...  Blustery.  Partly to mostly cloudy.  Low 9 to 14.  Wind northwest at 10 to 20 mph with gusts to 25 mph.
