Today’s Weather Summary for Northeast Minnesota and Northwest Wisconsin
A wide range in temperatures in the Northland Today with highs in the 50s and 60s with widespread low clouds, fog, and some drizzle occurring near Lake Superior, but farther inland it remained very warm and muggy Today with highs in the 70s and 80s under partly to mostly cloudy skies. Two fronts were over the Upper Midwest Today. Front number 1 stretched from Southern Minnesota to Central Wisconsin. Front number 2 was draped over Northern, Central, and Western Minnesota. Plenty of instability and moisture remained over our area Today and this led to more scattered showers and thunderstorms in parts of our area with locally heavy rain being the main threats out of this convection. Winds Today were out of the north or east at 5 to 15 mph.
