Winter storm tracks across northern Minnesota Tuesday
Another subzero arctic air mass blows in Tuesday night for Minnesota.
Minnesota’s next winter storm takes aim for the northeast.
A strong low-pressure system will track unusually far north for this time of year. That puts the heavy snow zone across southern Canada and northeast Minnesota Tuesday.
A winter storm watch is posted for northeast Minnesota Tuesday.

Snowfall totals
I like the looks of the Canadian model for snowfall totals across northern Minnesota Tuesday. A zone of 2 to 5 inches or so north of a Hallock to Duluth line looks reasonable. Snowfall totals will increase northward toward the Canadian border, where 5 to 10 inches is likely by late Tuesday.
Winds off of Lake Superior slamming into the higher terrain along the North Shore will produce lake-enhanced snowfall totals. Expect higher snowfall totals in the hills above Tofte through Grand Marais and Grand Portage.
Arctic air arrives Tuesday night
Gusty northwest winds behind the storm will bring another shot of bitter arctic air to all of Minnesota starting Tuesday night. Temperatures will reach subzero values across most of Minnesota Wednesday morning.
By Thursday morning the Twin Cities will see double-digit subzero readings, with negative 30s again up north.
Highs will moderate into the 20s again next weekend.
