The Storm Prediction Center has issued a Slight Risk — level two out of five — for both today and tomorrow, meaning organized severe thunderstorms are likely. The primary hazards include large hail, damaging winds between 40 and 60 mph, and heavy rain. Critically, storms are expected to fire up in the afternoon and push into the evening, landing right on top of the Monday and Tuesday commute windows.This isn't abstract. Mid-Michigan was already hit hard on Sunday — two-inch hail near Unionville and over 3,100 DTE and Consumers Energy customers lost power. Southeast Michigan is next in line for the same pattern.Fueling the risk: highs today near 87 degrees with high humidity and a moisture-laden southerly breeze creating the unstable air severe storms need to develop. Tomorrow holds in the mid-to-upper 80s before the pattern finally breaks.For commuters, plan for delays both afternoons — wet roads, reduced visibility, and possible downed branches or debris from wind gusts. Charge your phone, move patio furniture inside, and grab a rain jacket.The silver lining: Wednesday brings a dramatic cooldown into the mid-60s, a swing of more than 20 degrees in roughly 48 hours. Normal May conditions return for the rest of the week. But first, you've got to get through the next two days. Stay sharp, Detroit.This episode includes AI-generated content.
