DULUTH, MN – Cold air bites against Lake Superior this morning, turning every gust into a sharp reminder that winter has arrived for real. Snow flurries still drift in the wind, brushing cars and railings as Duluth heads into a colder, windier start to December.

Meteorologists warn that light snow may return by Tuesday, with northwest winds gusting up to 30 mph and temperatures stuck near 20°F. Even minor snow could lead to slick stretches along I-35, U.S. 2, and Highway 53, especially during the morning and evening commute windows. Visibility may drop briefly in blowing snow.

Monday stays mostly cloudy and brisk, highs near 18°F, before that next wave of Arctic air tightens its grip Tuesday night, sending lows plummeting into the single digits. By Wednesday, blustery sunshine offers little relief, with wind chills falling below zero across open areas near Proctor and Hermantown.

Residents should keep ice scrapers, emergency kits, and full gas tanks ready as early-season snow and cold persist through the first week of December. It’s the kind of pattern that can trigger flash-freeze conditions—wet roads refreezing rapidly after brief thaws during daylight.
