Detroit, Michigan – Scorching temperatures and stifling humidity are set to blanket Southeast Michigan on Thursday, July 24th, triggering a statewide summer weather alert. As heat index values soar to 101 degrees, health risks and travel headaches are expected for Detroit and neighboring communities—especially those along I-75, Woodward Avenue, and major city corridors.
According to the National Weather Service, a Heat Advisory will be in effect from 11 AM to 8 PM Thursday for Detroit, Ann Arbor, Flint, and surrounding counties. Hot air, combined with 70% humidity, will drive “feels like” temperatures past 100 degrees. Forecasters warn that even brief exposure can lead to heat exhaustion or heat stroke—especially for children, the elderly, and outdoor workers.
Local agencies are urging residents to stay in air-conditioned spaces, avoid outdoor activities during peak afternoon heat, and check on vulnerable neighbors. Detroiters should never leave children or pets in parked vehicles, as car interiors can reach lethal temperatures in minutes. Cooling centers across Wayne, Oakland, and Macomb counties will be open through the evening, while major roads—including I-75 and I-94—may see heat-related slowdowns and vehicle issues.
Thursday night brings a 50% chance of thunderstorms as the heat breaks, with storms possibly lingering into Friday. Showers and cooler air are likely Friday and Saturday, offering some relief, but another hot spell returns Sunday with highs back near 94°.
