MARQUETTE, Mich. – A stretch of bright Saturday skies across Michigan’s Upper Peninsula will give way to blustery winds and soaking rain by Columbus Day as a fast-moving fall front sweeps in from the west.
According to the National Weather Service in Marquette, dry conditions Saturday will yield to increasing clouds and showers late Sunday into Monday. Winds could gust up to 25 mph near Lake Superior, especially along U.S. Highway 41 and M-28, where wet pavement and reduced visibility may slow travel during the holiday return rush. The heaviest rainfall is expected Monday morning, tapering off by the afternoon as colder, drier air filters in.
Forecasters say temperatures will dip sharply by Tuesday, with highs only reaching the low 50s and early frost possible inland by midweek. Residents planning pumpkin patch trips, fall hikes, or leaf-viewing drives should prepare for slick roads and gusty winds through Monday evening. Drivers are urged to secure outdoor decorations and use extra caution on rural highways.
The mid-October chill will deepen after the front clears, bringing crisp, sunny afternoons but chilly nights across the Upper Peninsula. By Wednesday, calmer weather returns, setting up a pleasant stretch for outdoor cleanup and early Halloween decorating. However, the National Weather Service cautions that another round of light showers could develop late week.
