Detroit, Michigan – Weekend plans across southeast Michigan could take a hit Saturday as 90° heat, thunderstorms, and unhealthy air quality settle in.
According to the National Weather Service in Detroit/Pontiac, a 40–50% chance of thunderstorms is expected Saturday afternoon into Sunday evening. A cold front moving in will trigger scattered storms capable of producing wind gusts up to 40 mph, especially in metro areas like Detroit, Ann Arbor, and Warren.
The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has also extended an Air Quality Advisory through Saturday for St. Clair, Livingston, Oakland, Macomb, Washtenaw, Wayne, and Monroe counties. Ozone and fine particle pollution are expected to reach “Unhealthy for Sensitive Groups” levels due to firework smoke and stagnant air.
Residents are urged to avoid strenuous outdoor activities, especially those with heart or respiratory conditions. Use air conditioning with MERV-13 filters if available, and keep windows closed overnight.
Those traveling along I-94 or I-75 should monitor weather conditions closely Saturday afternoon and evening as visibility and road grip may be impacted during heavy rain. No severe storms are expected, but wind gusts and reduced visibility could still create hazards.
