MARQUETTE, Mich. – The Upper Peninsula wakes under a steel-gray sky this Monday morning, clouds thickening over Lake Superior as a chilly wind skims across the shoreline. The calm start is deceptive — a soaking stretch of fall weather is rolling in, and for many along U.S. 41 and M-28, it could mean wet commutes and rough lake conditions through midweek.
According to the National Weather Service in Marquette, widespread rain showers will spread across the region later Monday afternoon and continue on and off through Wednesday night. A few pockets of heavier rain may briefly reduce visibility, especially near Marquette, Munising, and Ishpeming. Winds from the south will strengthen to 20 mph, with gusts nearing 25 mph along the lakeshore. Boaters and shoreline visitors should exercise caution as waves increase through Tuesday.
Highs will hover in the upper 40s to lower 50s through midweek, while nights stay damp and brisk, dipping into the upper 30s. As the system clears out Thursday, cooler air settles in behind it — setting up the first real frost risk of the season by Friday morning. Rural valleys and interior U.P. towns could wake to temperatures near freezing as drier air filters south.
The weekend looks much calmer, with sunny skies and highs rebounding into the low 50s. But after days of steady rain, residents should give extra time for drying roads and soggy fields. Fall has firmly taken hold across northern Michigan — and winter’s first whisper may not be far behind.
