Converging lake breeze boundaries will trigger more scattered showers and thunderstorms today over inland areas of central and eastern Upper Michigan. Expect highs today mainly in the 70s with lows tonight ranging from the mid 40s inland to the 50s near the Great Lakes shores. Fall-like weather is expected by Friday in the wake of a strong cold front. High temperatures will drop into the low to mid 60s under the threat of scattered lake effect rain showers.
