The Storm Prediction Center had a Marginal Risk across S Wisconsin and part of West Michigan – generally west of a line from Saugatuck to Ada to Big Rapids. SPC said: “…this is where isolated marginally severe storms are possible. A weakening trend is expected with the loss of heating, thus the threat may only exist for a couple hours.”

Dry weather is expected from mid-morning today through Saturday.
