Winter storm warnings and winter weather advisories are in effect for much of central and northern Minnesota overnight into Monday morning, as a storm system may drop more than a half-foot of snow in some locations.
Near-record cold will descend on the state in the wake of the snow.
The heaviest snow is expected to fall from Moorhead east toward Brainerd, Duluth and Hinckley, where winter storm warnings are in effect. The National Weather Service said snowfall in the warning area may reach 6 to 10 inches by midday Monday.
The Weather Service said some parts of northwestern Wisconsin, near Lake Superior, could see up to a foot of snow. The Duluth-Superior area still is digging out from more than 20 inches of snow last weekend.
The Twin Cities metro area is in line for 2 to 5 inches of snow, with most of that falling on Monday morning.
"Snow will bring significant slowdowns to the Monday morning commute, so plan on extra travel time," the Weather Service's Twin Cities office reported.
The higher snow totals should be in the north metro.
Far southern Minnesota along the Interstate 90 corridor, and far northern Minnesota along the Canadian border, may see only a trace to an inch of new snow.
In the wake of the snow, arctic air will sweep across the state on northwest winds. High temperatures may not climb above zero across much of the state on Tuesday and Wednesday, with near-record lows in the teens and 20s below zero on Tuesday night into Wednesday morning.
The average high temperature for this time of year in the Twin Cities is 29 degrees; the average low is 15. In Duluth, the average high is 24, and the average low about 10 degrees.
