…A Few Storms Possible This Afternoon… Showers and a few thunderstorms will develop and expand in coverage just east of U.S.-31 and I-196 through mid afternoon. These showers and storms will then push east toward the U.S.-127 corridor into the early evening hours. Any storm will have the potential to produce some wind gusts to 40 mph and small hail up to the size of dimes, along with cloud to ground lightning. Locally heavy downpours will also be possible.
