Today’s Weather Summary for Northeast Minnesota and Northwest Wisconsin
A broad area of low pressure averaging 1002mb extended from Southern Saskatchewan to Eastern South Dakota late This Afternoon. Low level jet of up to 40 knots ahead of this low resulted in a warm air advection pattern over the area Today, and this eventually led to an area of snow or mixed precipitation which moved northeast into the Northland This Afternoon. A brief period of heavy snow did occur over parts of Northeast Minnesota This Afternoon with a quick half inch to one inch of accumulation reported in many areas from the Twin Ports, west and north.
Forecast Discussion for Northeast Minnesota and Northwest Wisconsin
Short Term Forecast – Confidence: High.
Tonight (November 8)
Occasional snow will fall over Northern Minnesota Tonight while showers of rain, sleet, or snow occur further south and into all of Northwest Wisconsin. Note: Precipitation should remain as all snow along and north of a line from Longville to Two Harbors, except near the immediate North Shore of Lake Superior where mixed precipitation is certainly possible.
The National Weather Service in Duluth has issued a *Winter Weather Advisory* which is in effect until 6 AM CST Saturday. This advisory includes Lake and Cook County in Northeast Minnesota. Use extreme caution if you have travel plans Tonight. Roads will be snow/slush covered and slippery. Slow down and allow extra time to reach your destination.
I’m still expecting 1-3″ of snow Tonight north of the Twin Ports with about an inch or less farther south. There is a possibility of a few 4-5″ totals though especially over the Arrowhead of Minnesota.
Mostly cloudy skies will be common Tonight with lows mainly in the 30s. East or south winds will turn westerly Overnight at 10 to 20 mph.
-My final snowfall accumulation map for Tonight’s event. Most areas north of Duluth should pick up 1-3″ of snow Tonight, but isolated totals of 4-5″ can’t be ruled out.
Saturday and Saturday Night (November 9)
Low pressure pulls off to our north/east during this period. Snow showers and flurries are possible over the Northland on Saturday with mainly dry weather Saturday Night. Highs will be in the 30s to lower 40s with lows in the teens and 20s. Winds will be out of the west or northwest at 10 to 20 mph.
Extended Forecast – Confidence: High.
Sunday through Tuesday (November 10-12)
A very cold airmass invades the Northland beginning Sunday Night and lasting thru Tuesday. A strong cold front is forecast to move through the area on Sunday with snow showers and flurries possible as that boundary comes through. Not expecting much in the way accumulations, maybe a half inch at best. Looks dry then next Monday and Tuesday although some lake effect snow showers could occur along the South Shore of Lake Superior in favored NW flow locations.
High temperatures on Sunday will be in the 30s to around 40 degrees. Highs on Monday and Tuesday will only be in the 20s with some Northern locales possibly remaining in the teens. Lows Sunday Night will be in the teens and 20s. Lows Monday Night will be in the single digits and teens.
Long Range Forecast – Confidence: High.
Temperatures should modify a bit during the middle/end of next week with values climbing back closer to seasonal averages. May see some rain or snow at times between the 15th-18th.
