Weather Summary for NE Minnesota and NW Wisconsin
Date:  March 8, 2016

The first widespread thunderstorm outbreak of 2016 occurred this morning in much of Northern Minnesota thanks to a warm front which lifted north across the state, this boundary interacted with a very unstable airmass which helped to generate scattered strong thunderstorms that went on to produce quite a bit of small hail in parts of Northern Minnesota this morning.

This afternoon finds low pressure averaging 1000mb centered over Central Minnesota with a cold front lifting northeast out of Southern-Central Minnesota.  Temperatures have warmed considerably in East Central Minnesota and Northwest Wisconsin this afternoon under a mix of sun/clouds, highs were in the 60s to around 70 degrees with dew points in the 40s to lower 50s.  Near Lake Superior and in extreme Northern Minnesota temperatures were in the 30s to around 40 degrees this afternoon with areas of fog and drizzle.  Winds today were out of the east, south or west at 10 to 20 mph.

Forecast Discussion for NE Minnesota and NW Wisconsin

Short Term Forecast - Confidence:  High.

Tonight (March 8)

Low pressure will move from Central Minnesota to Eastern Ontario Province tonight while high pressure builds southeast into Manitoba Province -- Mostly cloudy to partly cloudy skies will be found in our area with scattered rain showers affecting mainly Northern portions of Minnesota, there is a chance for the rain to mix with or change to snow showers/flurries later in the night but little if any snow accumulation is expected.

Note:  The atmosphere will remain quite unstable into early this evening in Northeast Minnesota and Northwest Wisconsin so there remains a possibility that a few thunderstorms will redevelop through mid-evening mainly over Northern or Northeastern Minnesota.  Low temperatures tonight will be in the 20s and 30s as winds shift from the south or west to the north/west at 10 to 20 mph.

Wednesday and Wednesday night (March 9)

A ridge of high pressure will stretch from the Upper Midwest to Central Canada.  Partly to mostly cloudy skies on the way tomorrow with highs in the 30s and 40s, there is a chance for a few rain showers which could mix with flurries or snow showers although no major accumulation of rain or snow is expected tomorrow.  Partly cloudy skies Wednesday night with lows in the 20s and 30s.  Winds will be out of the north, west or east at 10 to 15 mph.
