Upper Michigan Weather Update: Rain and Thunderstorms Return Wednesday

After a calm start to the week, weather across Upper Michigan is about to change. A midweek storm system is on the way, bringing rain, thunderstorms, and slightly warmer temperatures. Residents across the Upper Peninsula should prepare for wet roads, gusty winds, and possibly some stormy weather by Wednesday.

A Quiet Night Before the Storm

Tonight will stay calm, but skies will begin to cloud over gradually. According to the National Weather Service in Marquette, temperatures will drop overnight with cooler air especially in interior areas.

Overnight temperatures:

Interior counties: Low to mid-40s

Lakeshore communities: Upper 40s to mid-50s

While the night will be dry, it’s the calm before a wetter pattern sets in by Wednesday morning.

Storms Move In: What to Expect on Wednesday

By Wednesday, a developing system will spread rain and thunderstorms across much of northern Michigan. While the day starts off mild, conditions will turn soggy and stormy, especially in areas like Marquette, Escanaba, and towns along U.S. 41 and M-28.

Wednesday highlights:

Scattered to widespread showers and thunderstorms

Highs reaching lower to mid-70s

Heavy rain possible in some areas

Gusty winds, especially along the lakeshore

Some of these storms could bring downpours that affect visibility and slow down traffic. Travelers are advised to drive carefully, especially during the afternoon and evening.

Lakeshore Concerns and Travel Safety

Along the Lake Superior shoreline, scattered thunderstorms could bring brief periods of strong wind and heavy rain. While not expected to be severe, these storms may still cause power outages in isolated spots if stronger cells develop.

Safety tips for Wednesday:

Check the weather before heading out

Drive slowly during downpours

Avoid flooded areas on the road

Keep emergency flashlights and chargers handy in case of outages

Looking Ahead: Drier Weather Returns

The rain and thunderstorm chances will continue through Wednesday night, but clearing skies are expected later in the week. As the system exits the region, Upper Michigan should return to cool, dry conditions by Thursday and Friday.

Expect temperatures to stay seasonable, with more comfortable days ahead after this midweek blip.
