Marquette, Mich. – A stretch of raw fall weather will linger across the Upper Peninsula through Friday, with chilly air off Lake Superior fueling scattered lake-effect rain showers and a few snowflakes inland. While no snow accumulation is expected, overnight temperatures will dip low enough for patchy frost, especially across interior western counties.
According to the National Weather Service in Marquette, showers will continue through Thursday with highs in the 40s and lows dropping into the mid-30s. A few flurries may mix in overnight from Ironwood to Covington, where colder pockets will reach the lower 30s. The agency says showers should taper by late Friday as drier air arrives, though frosty mornings will persist into the weekend.
Motorists should be prepared for slick stretches on rural roads where wet leaves and brief bursts of sleet or graupel could cause reduced traction. Residents are encouraged to protect outdoor plants, disconnect hoses, and bring pets inside during the coldest nights.
Winds off Lake Superior will remain breezy through Thursday, keeping lakeshore communities like Munising and Marquette damp and cool before sunshine gradually returns Friday afternoon.
