The cold snap continues today as a strong upper-level low moves south and southeast across the central and eastern Great Lakes. At around 500mb (about 18,000 feet up), temperatures near the core of this system have dropped to an impressive -39°C, which is about -2 to -3 sigma for this time of year—quite remarkable for early November.
850mb temperatures in the Northland have stayed between -12 and -13°C for the second consecutive day, but the coldest air will gradually begin shifting south and east, moving away from our area by Monday.
Look at how far south this cold air is spreading today, with subzero 850mb temperatures reaching all the way into the southeastern U.S. According to the GFS model, temperatures this low in early November are about -2 to -4 sigma today and could drop to -5 to -6 sigma by Monday. It’s pretty rare to see such a strong surge of cold air pushing down to the Gulf this early in November.
Morning temperatures stayed steady, hovering in the teens and low 20s across the area, similar to what we saw on Saturday morning. Typical lows for November 9 in this region range from the low to upper 20s.
Today’s highs were mostly in the mid-20s to around 30 degrees, while typical highs for November 9 in our area range from the upper 30s to lower 40s.
More snow is expected to pile up tonight through Monday morning in the snowbelts of northern Wisconsin and upper Michigan, as chilly northerly winds sweep over the warmer waters of Lake Superior. Winter Storm Warnings and Advisories remain in effect for these regions.
Snow showers passing through the Northland today are expected to continue into the evening but should taper off later tonight, leading to mostly dry weather on Monday.
An exception to this will occur along the south shore of Lake Superior in northern Wisconsin, where lake-effect snow will persist into Monday morning. Additional accumulations of 2 to 5 inches are expected from the Bayfield Peninsula to Ashland, Gile and Hurley, with the highest totals likely near Gile and Hurley.
Radar loop ends 5:02 PM Sunday, November 9, 2025.
As warmer air moves in Monday night, some energy (green, yellow and orange on the loop below) ahead of it could bring a few snow showers or patchy mixed showers across northeast Minnesota. However, snow accumulation is expected to be minimal, and most people likely won’t see any snow at all Monday night.
On Tuesday, a fast-moving system with its warm and cold fronts will sweep across the Northland. While little to no precipitation is expected, the winds will pick up, as is common with these clipper systems.
NAM model 500mb vertical velocity forecast valid 6 PM Monday to 6 AM Tuesday.
Later this week, an amplified weather pattern might develop, with two strong troughs to the west and east and a ridge in between over the Plains. Whether or not the Northland sees rain next weekend (November 15-16) will depend on how the western trough evolves, as it could split into two parts, one heading south and the other north.
Over the next 7 days, only one out of 20 GEFS ensemble members predicts at least 2 inches of snow in Duluth, making the chances of that happening extremely low.
