Warm and humid over the weekend; Risk of storms mainly on Sunday
A cold front is currently located over the Upper Peninsula, Wisconsin, Iowa and northern Missouri — it is moving very slowly eastward. With a sultry air mass in place, there could be an isolated pop-up shower or storm Saturday afternoon. A higher chance of showers/thunderstorms will move through Northeast Michigan Sunday midday-afternoon.
To the east of the cold front, high temperatures soared to the upper 80s and lower 90s. Highs reached 88 degrees in Alpena, 89 degrees in Traverse City and 93 degrees in Chicago. To the west of the cold front, high temperatures were only in the 70s, Ironwood had a high of 70 degrees and 74 degrees in Duluth. The change in the weather pattern will be slow to evolve, it will take until Tuesday for cooler temperatures to arrive in Northeast Michigan.

The chance of showers will become lower again Sunday night and through most of the daytime hours on Monday. The chance of showers will then increase Monday evening.
