DULUTH, Minn. – Gray skies hover over Lake Superior early this Sunday morning, with the calm before another fall shift already in the air. The breeze is light now, but that will change — southeast winds will strengthen over the next 24 hours, setting up a blustery and unsettled start to the new week.
According to the National Weather Service in Duluth, Sunday will stay mostly sunny and mild, with highs near 57°F. Winds will increase through the day, gusting up to 20 mph along the lakefront. By Monday afternoon, clouds return as moisture builds from the southwest. The first round of scattered showers could reach the Twin Ports region late Monday night, followed by steadier rain Tuesday and Tuesday night.
Tuesday’s system will bring breezy conditions, especially near the shore where gusts may exceed 25 mph. Rainfall totals remain modest — generally a quarter inch or less — but slick roads and reduced visibility may affect travel along I-35 and U.S. Highway 53. Residents should secure loose decorations ahead of gustier conditions and prepare for damp commutes early Tuesday.
By midweek, skies begin to clear and temperatures drop slightly into the upper 40s — a noticeable shift toward November’s chillier air. The good news: Halloween Friday is shaping up beautifully, with dry skies, light winds, and crisp evening air perfect for trick-or-treating across St. Louis County and the North Shore.
Still, longer-range models hint at a colder November ahead, with early signs pointing to frost and perhaps the season’s first flurries by next weekend.
