Drivers and residents across Michigan’s Upper Peninsula should be on high alert this Sunday as scattered thunderstorms threaten to disrupt travel, especially on key highways like US-41 and M-28. The National Weather Service in Marquette has warned of gusty winds, heavy downpours, and reduced visibility during storm activity. If you’re traveling or attending outdoor events, keep an eye on the sky and be ready to act quickly.
Thunderstorms Likely Across Upper Michigan Sunday
After a stretch of unsettled weather, more storms are expected to move through the region Sunday afternoon into the evening. These thunderstorms could bring:
Sudden heavy rain
Gusty winds up to 20 mph
Brief periods of reduced visibility
Slick roads from water pooling on the surface
Communities including Marquette, Houghton, and Ironwood may all see active weather during peak travel hours. Even though the storms may be scattered, they could develop quickly and move fast, leaving little time to prepare.
Travel Hazards on US-41 and M-28
Drivers along US-41 and M-28—the two major highways crossing the Upper Peninsula—should take extra precautions. Wet roads combined with heavy rainfall can lead to hydroplaning and longer stopping distances. If you’re on the road during a storm:
Slow down and maintain extra distance between vehicles
Avoid sudden turns or braking
Turn headlights on even during the day for better visibility
Pull over safely if visibility drops suddenly
Storm conditions can change fast in the U.P., especially with winds picking up around the Great Lakes region.
Storm Safety and Outdoor Event Cancellations
Anyone planning to attend outdoor events or go hiking, fishing, or camping in the U.P. should prepare for possible delays or cancellations. The National Weather Service urges residents to:
Move indoors at the first sound of thunder
Stay away from tall trees or open fields during storms
Report any hail or wind damage to the NWS Marquette office
Sunday’s storm threat is not expected to be widespread severe, but even non-severe storms can still cause damage or lead to dangerous travel.
Calmer Weather Returns Early Week
After a stormy Sunday, Monday will offer a break with mostly sunny skies and a high near 62°F. The rest of the week looks even better, with a gradual warm-up and dry conditions.
