Otherwise, there were many reports of 1/4 inch diameter hail and wind gusts of 35 to 43 knots (40 to 50 mph) with the thunderstorms as the cold front moved to Lake Michigan. A low-level jet fed moist, unstable air into the storms, while afternoon maximum temperatures peaked in the lower 70s with dewpoints of 55 to 60.
