Strong thunderstorms possible overnight through Friday early morning

A frontal system from the Northern Plains in tandem with afternoon heating have produced scattered thunderstorms over Upper Michigan, continuing until early Friday morning once the system lifts northeast of the region.

Storms can produce damaging hail and winds plus brief downpours resulting in localized flooding as well as flash flooding -- NWS Alerts HERE.

Rounds of rain and thunderstorms continue from Friday afternoon through Sunday as a Northern Plains frontal system sweeps west through east over the region.

Temperatures and humidity overall trend above seasonal until the weekend, with a cooldown, drier period early next week as the jet stream dips south of the Upper Peninsula.
