Low pressure over southern Alberta this evening is forecast to move quickly to the southeast, reaching southwest Lower Michigan by Monday evening. This system is expected to bring another round of snow to mainly southern portions of the Northland from early Monday morning thru about midday Monday, with the snow spreading from NW to SE. Snowfall amounts ranging from a trace to 2 inches are possible in a NW-SE swath on Monday including the Cass Lake, Walker and Brainerd Lakes area, toward Aitkin and Hinckley and into northwest Wisconsin. It looks like the Twin Ports will be on the north edge of Monday’s system, but if it shifts slightly farther north, then some snow would also impact Duluth and Superior in the 6 AM to Noon time frame.
Seasonal snowfall total for 2020-2021 is up to 28.7″ at Duluth, Minnesota, this is +21.0″ above normal to date.
We’ve had 16.7″ of snow so far this month in Duluth, the normal snowfall for November is 13.7″. Note: Snowiest November on record at Duluth was in 1991 with 50.1″ of snow, it’s unlikely that November 2020 will end up as the snowiest November on record, but a top 10 snowiest November is a possibility.
Note: There remains some uncertainty on where Monday’s band of snow will setup, with the HRRR model showing it farther north compared to the NAM model.
18z HRRR model radar forecast valid Midnight tonight to 3 PM Monday.
18z NAM 3km model radar forecast valid Midnight tonight to 3 PM Monday.
A look at last night’s surprise winter storm which impacted a small portion of the Northland as it intensifies while pulling NE of the Great Lakes this afternoon, while upstream is Monday’s system which moves quickly SE out of western Canada.
Note: The good news is after Monday’s system, the rest of this week looks fairly quiet (weather-wise) across the Northland with milder temperatures for mid to late week.
