Light snow possible tonight; mainly dry Monday-Wednesday; warming trend begins midweek

It’s been a very snowy winter so far, especially near Lake Superior.

Seasonal Snowfall Totals and Departure from Normal from October 1, 2019 to January 18, 2020.

Marquette, MI: 111.9″; +13.4″ above normal
Duluth, MN: 70.4″; +24.5″ above normal
International Falls, MN: 47.9″; +7.5″ above normal
Eau Claire, WI: 38.2″; +15.0″ above normal
Green Bay, WI: 36.3″; +11.6″ above normal
Minneapolis, MN: 32.3″; +3.3″ above normal


Ice coverage on Lake Superior has increased this week to ~7%, but this is still below the long term average which is ~15% for late January.


This week will start off chilly (close to normal) in the Northland, but a warming trend begins midweek, and the warmer than normal temperatures look to continue into early February per long range model guidance.

Note: I don’t see any subzero temperatures occurring in Duluth through early February, although we might get close tonight and again Monday night, but after that chances for a subzero temperature are very low.

…Weather Summary…

A skiff of snow tonight, otherwise mainly dry the next few days with warmer temperatures by midweek.

A trough lingering over the Northland will produce a little snow in parts of the area tonight. Light snow this afternoon has dropped visibilities to around 1 to 4 miles in northern Minnesota, and this area of light snow is forecast to move south through the night. Accumulations should be light, generally a few tenths of an inch.

Partly to mostly sunny skies are expected Monday and Tuesday as high pressure passes through the Midwest.

Lows tonight will range from the teens below to single digits above zero with highs on Monday in the mid teens to lower 20s, warming to the mid teens to mid 20s on Tuesday.

Looks like will get into the mid 20s to mid 30s for highs on Wednesday.

There is a chance for some snow in parts of the Northland late this week (Thursday-Friday time frame) An easterly wind is also possible late this week which could cause some lake effect snow near Lake Superior, but temperatures might be a little to warm for lake effect snow, will just have to wait and see.
