Today’s Weather Summary for Northeast Minnesota and Northwest Wisconsin
Strong northeast winds of 15 to 30 mph occurred Today near Lake Superior as the marine layer strengthened. A stationary front was down along the Minnesota-Iowa border with a couple rounds of heavy rain and thunderstorms occurring along and north of that front from Central, Eastern, and Southern Minnesota into portions of Wisconsin. The northern edge of This Morning’s thunderstorm complex did affect Southern parts of the Duluth area, generally south of a line from Leader, Minnesota to Park Falls, Wisconsin with some decent rainfall per doppler radar estimates. The warmest temperatures Today were in far Northern Minnesota with mid 70s to lower 80s, elsewhere highs were in the 60s and 70s which is actually a little below average for a change. Dew points were in the 50s and 60s with upper 40s nosing into the Arrowhead. Winds away from Lake Superior were out of the east at 5 to 15 mph.
-Doppler radar rainfall estimates from Today. Some decent rainfall totals in Southern parts of our area Today, generally in the 1/4-1/2″ range, but a few spots picked up >1.00″ of rain.
Today’s Upper Level Analysis:
Upper troughs were over Eastern Canada and west of the Rockies with an upper level ridge extending from the Rockies, east through the Plains, Southern U.S., Ohio Valley, and Eastern U.S per RAP model analysis. North of this ridge was a westerly flow with an upper level disturbance heading east out of the Northern Plains per water vapor satellite imagery. 850mb temperatures as of 3 PM ranged from +20 to +22C in Southern Minnesota to +14C in Northeast Minnesota to +16 to +18C in Western, Central, and Eastern Minnesota.
