About lightning in Michigan
Michigan gets a steady run of warm-season thunderstorms, with lake breezes off the Great Lakes and passing fronts shaping convection across both peninsulas. Storms often fire in the afternoon and can intensify near the shorelines. Activity runs May through August. With lake-modified storms that develop fast, the live distance to the nearest strike and its trend are the safer guide than thunder alone.
