High pressure of 1028mb was over Southern Manitoba Province this afternoon.  Mostly sunny skies were found across northern Minnesota today while clouds along with a few peeks of sun were more common in eastern Minnesota and northwest Wisconsin.  Scattered snow showers have also occurred today mainly around Lake Superior thanks to a very cold airmass that has moved over the lake today.  High temperatures today were in the 30s with west or north winds at 5 to 15 mph.

Forecast Discussion for NE Minnesota and NW Wisconsin

Short Term Forecast - Confidence:  Medium to High.

Tonight (April 4)

Clear to partly cloudy skies tonight.  High pressure will pass over the Upper Midwest this evening, exiting to the east later in the night.  Low temperatures will be in the teens and 20s with single digits and possibly even subzero low temperatures once again over far northeast Minnesota.  Winds will be out of the west or northwest at 5 to 15 mph during the evening, shifting to the south/east at 5 to 15 mph late.

Tuesday and Tuesday night (April 5)

An area of low pressure will track east/southeast out of the Northern Plains on Tuesday -- Clouds will be on the increase in the morning which will be followed by wet snow and rain from Tuesday afternoon into Tuesday night, there could also be some patchy sleet mixed in as well.

Note:  The main band (heaviest precipitation) is expected to pass through portions of the Northland from mid afternoon through the evening hours the way it looks now.

Highs on Tuesday will be in the 30s to around 40 degrees with lows mainly in the 30s.  With the warmer temperatures in place the snow that does fall will likely be the wet/slushy kind.

Extended Forecast - Confidence:  Medium.

Wednesday through Friday (April 6-8)

Low pressure is forecast to move east/southeast across the Upper Midwest to southern Lower Michigan during the day Wednesday -- More wet snow and rain is possible in our area on Wednesday although precipitation should be on the light side.

A clipper like system dives into the Upper Midwest for Wednesday night and Thursday bringing another round of wet snow or rain to the Northland.

Snow showers could linger on Friday due to a trough that will be over the region.

High temperatures on Wednesday and Thursday should top out in the 30s to near 40 degrees with low temperatures Wednesday night and Thursday night in the 20s and 30s.  Highs on Friday will be in the 20s and 30s.
