Today’s Weather Summary for Northeast Minnesota and Northwest Wisconsin
An arctic airmass is in complete control Today with a strong 1044mb high pressure ridge stretching from Western Minnesota to Eastern Nebraska. Note: At 11 AM Today the pressure was at 1050.2mb or 30.93″ of mercury at Fargo, North Dakota, if this is verified then this would be an all-time record high barometer reading during the month of November at Fargo, North Dakota. Another very impressive thing were the 850mb temperatures Today which ranged from -20 to -24C across the Northland and over Lake Superior. One good thing about arctic air is the amount of sunshine that usually occurs since the air is so dry. High temperatures Today were only in the single digits and teens with north or northwest winds at 10 to 20 mph. Lake effect snow has been occurring along the South Shore of Lake Superior Today with the most significant accumulations over Iron County.
