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.
Forecast Discussion for Northeast Minnesota and Northwest Wisconsin
Short Term Forecast – Confidence: High.
Tonight (November 23)
Strong area of high pressure will remain in control of our weather Tonight as it slides slowly south/east during the night. A warm air advection pattern will develop later Tonight as this high moves away. Lows Tonight will range from around 10 below to 10 above zero with winds turning from the north-northwest to the southwest at 5 to 15 mph. Note: Lake effect snow will be diminishing Tonight along the South Shore of Lake Superior as winds back to the west. Clear to partly cloudy skies are forecast Tonight with more clouds possibly moving in Overnight.
Sunday and Sunday Night (November 24)
Low pressure will be centered to our north with high pressure to our southeast. Attached to that low will be a warm front and cold front. Those boundaries will be moving through the Upper Midwest during this period. A warm air advection pattern could lead to some light snow, flurries, and patchy light freezing drizzle from Sunday Afternoon into Sunday Night but any accumulation should be minimal. Temperatures during this period will be in the teens and 20s. Winds will be out of the south or southwest at 10 to 25 mph.
Extended Forecast – Confidence: High.
Monday through Wednesday (November 25-27)
Snow showers and flurries could occur at times through this period as a NW flow remains in place and embedded within that flow will be a few disturbances which could trigger scattered snow from time to time, but accumulations look to remain on the light side. High temperatures on Monday will be in the 20s and 30s with lows in the single digits and teens. Highs on Tuesday will be in the teens and 20s with lows in the single digits and teens. Highs on Wednesday will be in the teens and 20s.
Long Range Forecast – Confidence: High.

No major winter storms on the horizon, but the weather pattern might get a little more active with the potential for 1 or 2 minor snow events affecting the Northland during this period. Below average temperatures should also continue.
