Areas west of the Twin Ports are mostly done with this round of snow, but the rest of the Northland will have heavy snowfall overnight into Monday morning. A slick morning commute is likely Monday.

Monday’s snow will primarily be over the Arrowhead region and the South Shore as this system slowly moves east. By 10 pm Monday, conditions will be clear west of Ashland County. By 5 am Tuesday, the rest of the area will have clear skies.

Over a foot of additional accumulation is expected along the South Shore.

A Blizzard Warning is in effect for Douglas, Bayfield, Ashland, Iron, and Gogebic Counties because of the additional accumulations combined with winds up to 45 mph. There is also a Blizzard Warning for the North Shore of Cook County because of the strong northwesterly winds that could cause blowing snow and reduced visibility tonight.

A Winter Storm Warning is in effect for Washburn, Sawyer, Price, Lake, and northern Cook Counties. All Blizzard and Winter Storm Warnings expire at 7 pm Monday.

A Winter Weather Advisory is in effect for St. Louis, Carlton, Pine, Burnett, and southern Itasca Counties until 1 am tonight.

Ongoing flooding remains a concern- with afternoon highs in the low forties this week, this new snow is expected to melt quickly. There is also a chance of rain Wednesday, becoming snow Wednesday night. Snow chances continue from then through the weekend.
