Persons planning outdoor activities late this afternoon and early this evening should consider the likelihood of strong thunderstorms with a potential for damaging winds, hail, intense cloud-to-ground lightning, and heavy downpours.

It would also be prudent for boaters on southern lake Michigan to be aware of this weather situation and be prepared to reach harbor should a marine warning be issued.
