The map above is the early afternoon updated Severe Weather Outlook Map from the Storm Prediction Center. They have put Southern Lower Michigan in the Marginal (dark green on the map) Severe Weather Risk Area for today. SPC says:

"A few thunderstorms will be possible along a surface cold front and in advance of a mid-level trough crossing the upper Great Lakes. Destabilization in advance of the front may be sufficient for a few strong storms with marginally severe wind/hail as far east as southeast Lower MI later this afternoon."

If storms develop during the midday/afternoon, there is a chance of isolated strong wind gusts or hail. The threat of a tornado is not zero, but it will be very small. Some areas won’t see any rain at all. Here’s Grand Rapids radar:

We’ll be tracking the showers and storms today. They will clear out this evening and we’ll be mostly sunny, dry, a little cooler and a little less humid for the weekend.
