Heavy, blowing snow and a cooldown expected for Thanksgiving week

The first snowstorm of the season is predicted to fall on the Northland on key Thanksgiving travel days.

The weather system will move west to east, with snow predicted to begin falling in Minnesota the morning of Tuesday, Nov. 25. The National Weather Service offices in Duluth and Grand Forks issued a winter storm warning was Monday, which is in effect from 6 a.m. Tuesday through noon Wednesday. The warned area stretches from Becker County eastward through Mille Lacs and Pine counties, across the Arrowhead and into northern Wisconsin along the South Shore of Lake Superior.

Heavy snow rates over a two- to five-hour period Tuesday could reduce visibility to less than a half-mile in northwestern Minnesota. Northerly winds of 25 to 30 mph, combined with moderate to heavy snow rates, will likely lead to blowing snow in these areas.

Travel could be very difficult and the hazardous conditions could impact the Tuesday morning and evening commutes, depending on where you are in the state.

As the weather system moves east, the Duluth National Weather Service Office predicts the lake effect will extend snow impacts into Wednesday and Thursday.

After the snow moves on, a spokesperson for the Duluth office said temperatures will plummet.

“We're looking at high temperatures only in the 20s with lows in the teens to single digits," she said. "And this much colder air mass moves in on Wednesday and then lingers through at least next weekend.”

About 3-6 inches of snow is expected to fall over much of the state, with amounts exceeding a foot of snow possible on the North Shore.
