Detroit is heading into a much more active stretch of weather starting Saturday and lasting at least through Tuesday, with temperatures climbing into the upper 70s and 80s and humidity rising along with them.
The pattern does not mean every hour will be rainy, but it does bring periodic chances for showers and thunderstorms each day. Some storms could become strong to severe, and Monday is expected to be the hottest day of the stretch, with temperatures possibly reaching the middle 80s. Heavy rainfall may become a concern by Tuesday if the active pattern holds.
Tonight remains relatively calm by comparison, with partly cloudy skies, lows in the mid 50s and south winds at 5-10 mph. Saturday is expected to start with showers and storms possible in the morning before turning partly sunny in the afternoon, with highs near 80 degrees and southwest winds at 10-20 mph. Sunday brings patchy fog early, then partly sunny conditions with isolated showers and storms late and highs near 80 degrees.
The broader setup is what makes this weekend stand out. Warmer, more humid air is pushing north across the Midwest and Great Lakes, putting southeast Michigan in an active corridor where stronger storms could develop or move through from Saturday through Tuesday. The highest concentration of organized severe weather initially appears west of Detroit, but the threat does not stop at the city line.
That is the tension in the forecast: the day-to-day outlook still leaves room for dry hours, but the atmosphere is becoming more favorable for storms that can turn stronger at times. For Detroit, the practical answer is simple. The region is entering several days of stop-and-start storm chances, with Monday carrying the warmest air and Tuesday bringing the added concern of heavier rain.
