Temperatures will remain well below normal in Duluth at least thru early next week, but we may begin to climb out of this arctic air mass starting around the middle of next week or after February 15, but even that isn’t a lock since it’s so far out in model land. Note: Normals this time of year in Duluth range from the low to mid 20s for highs, and around 5 above zero for lows, so even with the possibility of milder temps around the middle of next week they still look to be below normal for this time of year.

The arctic air is locked in and shows no signs of leaving at least thru early next week. Wind chill headlines have been extended thru this weekend as will continue to have dangerously cold wind chills in place over the next several days. No surprise with the arctic air mass overhead that we likely won’t be seeing any snow around here this week, and probably into next week as well (at least thru early next week) So for now it’s all about the bitterly cold stretch of weather, and continued very dry pattern.
The widespread nature of this arctic air mass is pretty amazing!

The dangerously cold wind chills could cause frostbite on exposed skin in as little as 10 minutes.
Wind chill alerts remain active across much of the Northern Plains and upper Midwest.

Lake effect clouds/snow showers continue over Lake Superior (east of the North Shore) today, but with a westerly or a west-southwest wind continuing, most of the lake effect snow remains off-shore, except over the Keweenaw and Bayfield Peninsulas (yellow outlined areas on map) where some lake effect snow continues at times.
Also of note continues to be the lack of ice over Lake Superior, with only 6.5% of the lake covered by ice as of Monday morning, February 8, 2021 – Normal at this time of year is around 35%.

A piece of the Polar Vortex (mid/upper level low) continues to move west-southwest out of Hudson Bay and into northern Manitoba this afternoon. This upper low is forecast to start digging more to the south by late this week, and could move over the Northland sometime in the Friday-Sunday time frame.
Note: On the front side of the aforementioned upper low we could see a disturbance lift NE on Thursday bringing a period of snow to parts of the Northern Plains and upper Midwest, but at this time it looks like this snow would remain south of the Northland.

The winter of 2020-2021 continues to run warmer than average across the region thanks to a very mild December and January, but February has started off very cold, and it looks to remain that way for a while longer, so it’s certainly possible we could see the average temps for this winter trend a lot closer to normal by the end of this month, will be interesting to see what happens over the next few weeks.
