MARQUETTE, Mich. – A damp Halloween dawn greets Michigan’s Upper Peninsula, with gray skies, slick pavement, and a biting north wind hinting at the seasonal shift ahead. Umbrellas and heavier jackets will be needed as moisture deepens across Lake Superior’s southern shore, setting the stage for a chilly weekend where rain may briefly turn to flakes.
According to the National Weather Service in Marquette, widespread showers will expand through the day as a cold front settles across the region. Gusts up to 20 mph could reduce visibility near open stretches of U.S. 41, while temperatures hover in the mid-40s before falling into the 30s this evening. Late tonight, colder air filters in from the northwest, allowing a few higher-elevation areas to see a rain-snow mix before dawn Saturday.
Saturday remains cool and mostly cloudy, with scattered light showers lingering and highs barely touching the mid-40s. Skies partially clear by evening as calm winds take hold, leading to lows near freezing. Sunday offers a brief window of brightness before another system pushes back in Sunday night, bringing renewed rain chances and a sharper chill to start the new week.
Meteorologists note that the combination of damp air and nighttime lows in the low 30s could bring the season’s first slick patches on rural roads and bridges. Residents are urged to clear gutters, secure decorations, and prepare vehicles for colder mornings.
Models continue to suggest more frequent snow potential heading into early November as colder Canadian air begins to grip the Upper Great Lakes.
