Minnesota Weather Alert: Dense Fog Blankets Duluth as Cooler Air and Rain Move In Friday
DULUTH, MN — A thick blanket of dense fog rolled across Lake Superior and the Duluth harbor early this morning, cutting visibility to near zero in parts of northeast Minnesota. The National Weather Service in Duluth issued a Dense Fog Advisory through late morning for Duluth, Two Harbors, Grand Rapids, and the Iron Range, warning drivers to slow down, keep low-beam headlights on, and allow extra time for travel.
Fog Lingers Before Clouds and Cooler Air Return
The fog is expected to lift gradually by midday, but skies will remain mostly cloudy with highs near 47°F. Light southerly winds will shift northwest later in the day, bringing a noticeable chill by evening. Overnight, clouds linger ahead of a cold front that’s set to move through Friday.
Friday Forecast: Cooler and Damp
Friday’s highs will hover around 48°F, with a 30% chance of light showers spreading across the region by afternoon. Wind gusts up to 15 mph may add a brisk edge along the lakeshore, and cooler air will settle in behind the front. By Saturday, highs will only reach the mid-40s, keeping the weekend seasonably cool for late October.
Weekend Outlook: Dry Start, Showery Finish
Saturday looks partly sunny and dry, perfect for outdoor errands or late fall yard work. However, by Sunday, another weak system will bring passing showers and breezy west winds, with temperatures remaining in the 40s and low 50s into early next week.
Early Signs of Winter Ahead
Long-range forecasts suggest colder trends developing across the Upper Midwest, with the first snow chances by mid-November — particularly for the Arrowhead region and higher inland elevations. While no major winter system is expected yet, meteorologists say this pattern marks the start of a steady shift toward winter conditions.
Fog, rain, and falling temperatures — it’s a clear reminder that Minnesota’s calm fall mornings are giving way to winter’s slow approach.
