Blustery and turning Colder! A few snow showers or mixed rain-snow showers at times over the next few days; Warming trend possible 2nd week of November

Strong cold air advection will take place in the Northland over the next few days as 850mb temperatures drop to between -5 to -8C Sunday and Monday, and from around -8 to -12C on Tuesday, by far the coldest air mass we’ve seen so far in the fall of 2021.

High temperatures will generally run from the mid 30s to low 40s in northeast Minnesota and northwest Wisconsin from Sunday through Thursday with overnight lows in the 20s, but some teens are possible in the typical cold spots.

It will also be windy especially tonight and Sunday as the cold air rushes in, with northwest winds at 10 to 20 mph with gusts >30 mph likely in our area for tonight and Sunday.

Scattered snow showers or mixed rain and snow showers are possible in the Northland Sunday, Monday and Tuesday, with some snow accumulation possible downwind off some of the larger inland lakes across northern Minnesota, and also along the South Shore of Lake Superior in northern Wisconsin.

Note: It doesn’t look like will see any accumulating snow in Duluth and Superior over the next few days, but we likely will see some snow flurries from time to time, even near Lake Superior.

The Northland will be in a N-NW flow aloft through Thursday, but after that the pattern looks like it may shift a bit, with more of a westerly flow possibly developing across the upper Midwest by next weekend.

It’ll be chilly most of the week ahead, but milder temperatures could return to our area by next weekend and beyond with perhaps a few more 50 degree days possible between November 6-12.
