Lansing, MI — Michigan is bracing for another surge of Arctic air beginning late Wednesday night, bringing extreme cold, dangerous wind chills, and renewed lake-effect snow that could pile up as much as 11 inches in parts of the Upper Peninsula, according to forecasters.
The incoming cold snap is expected to linger through the workweek, creating hazardous travel conditions and life-threatening exposure risks across multiple regions of the state.
Lake-effect snow targets Upper Peninsula
Forecasters with the National Weather Service say light to moderate lake-effect snow will continue to impact the Copper Country, with conditions worsening in eastern sections of the Upper Peninsula.
“Travelers should leave extra time and be prepared for difficult driving conditions, especially in the east,” the National Weather Service office in Marquette said in a Wednesday update.
According to probabilistic snowfall data, eastern Upper Peninsula counties could see up to 11 inches of snow within a 24-hour period, with the highest totals expected near Grand Marais.
Extreme cold warning issued
Alongside the snow, brutally cold air is spreading back into the region. An Extreme Cold Warning is in effect for northern Michigan and the eastern Upper Peninsula, where wind chills are forecast to plunge between -15°F and -30°F.
“Bundle up if you must go outside, especially after dark, and watch out for family, neighbors, and pets,” the National Weather Service Gaylord advised.
Forecasters warn that frostbite can occur within minutes under these conditions, particularly on exposed skin.
Winter weather advisories remain active
Multiple regions across Michigan remain under Winter Weather Advisories through Thursday morning, including:
- Southwest Lower Peninsula
- Northwest Lower Peninsula
- Western and eastern Upper Peninsula
Snowfall totals in these advisory areas are expected to range from 2 to 11 inches, with blowing snow likely to cause sudden whiteout conditions during travel.
“Visibility can drop quickly under lake-effect snow bands, even when totals are modest,” forecasters said.
Winter storm warnings in eastern U.P.
More severe conditions are unfolding in parts of the eastern Upper Peninsula, where Luce, Alger, and Schoolcraft counties remain under a Winter Storm Warning until Thursday morning.
Officials say road conditions in these counties could deteriorate rapidly as intense snow bands persist.
Residents and travelers are urged to avoid unnecessary travel and carry emergency winter supplies if driving is unavoidable.
Flood advisory continues in central Michigan
While snow and cold dominate much of the state, ice-related flooding remains a concern in central Michigan.
The Muskegon River, particularly in Newaygo County, is under a Flood Advisory due to accumulating ice chunks that could lead to localized flooding through Wednesday night.

Residents are asked to report flooding immediately to local emergency services or law enforcement.
Hazardous conditions on the Great Lakes
Dangerous marine conditions are also ongoing. A Heavy Freezing Spray Warning remains in effect for Lake Superior, where rapid ice accumulation on vessels and infrastructure could cause significant damage or instability.
Mariners are strongly advised to remain in port until conditions improve.
Cold pattern shows little sign of easing
Meteorologists say this extended period of cold and lake-effect snow shows no immediate signs of breaking, keeping temperatures well below normal and winter hazards elevated across Michigan.
Residents are urged to limit outdoor exposure, check on vulnerable individuals, and stay alert to local warnings as conditions evolve.
