Marquette, Mich. – A sharp cold front swept across Michigan’s Upper Peninsula this morning, bringing a burst of showers, rumbles of thunder, and a fast drop in temperatures that will linger through the end of the week. Afternoon highs, once in the 70s earlier this week, will now struggle to break the 50s across much of the region.
According to the National Weather Service in Marquette, rain showers will redevelop this afternoon and continue into Friday, with lake effect bands forming off Lake Superior under persistent west to northwest winds. The chill will be most pronounced in Marquette, Houghton, and Ironwood, where highs will remain in the lower 50s. Farther east, Munising and Newberry may hold near the low 60s today before the cooler air spreads eastward.
Drivers should prepare for wet pavement and reduced visibility, especially along U.S. 41, M-28, and county roads near the shoreline where lake effect rain will be heaviest. Outdoor plans may need to shift indoors as gusty winds and raw conditions persist.
Cool, damp weather will hold into the weekend, and additional advisories are possible if lake effect showers intensify.
