By 5:40 a.m. today, Detroit was already waking up warm, with clear skies and temperatures near 81°F. Any hint of morning relief will not last long. Highs are expected to soar into the upper 90s today, and overnight lows in the mid-70s mean it will stay muggy and uncomfortable well after dark, especially for anyone without air conditioning.
Dangerous Heat Through Thursday
An Extreme Heat Warning is in place through 8 p.m. tomorrow, according to the National Weather Service Detroit. Forecasters are calling for a high near 98°F today, with heat index values that could spike to around 108°F. West to southwest winds of 8 to 14 mph, with gusts into the 20s, will offer movement in the air but not much actual cooling.
Officials warn that spending long stretches outside in this kind of heat can quickly lead to heat-related illness. Residents are urged to limit strenuous activity during the hottest part of the day, seek shade or air conditioning when possible, and pay extra attention to vulnerable neighbors, older adults, and anyone who works outdoors.
Afternoon Heat And Gusty Winds
Temperatures are expected to climb fast after late morning, then hang in the mid to upper 90s from about 1 to 6 p.m., with the most intense heat between 3 and 6 p.m. A steady west to southwest breeze could bring gusts near 22 mph, but the thick humidity will keep it feeling much hotter than the actual thermometer reading.
If you have to be outside, try to schedule heavy work or exercise for early morning or later in the evening, when readings are at least somewhat lower, and build in frequent water breaks to avoid overheating.
Where To Cool Off
Detroit Recreation Centers and many Detroit Public Library branches are operating as formal cooling centers, though hours and availability can vary by location. The city keeps an updated list of cooling sites and guidance for residents on the City of Detroit website. Residents can also call the Detroit Health Department at (313) 876-4000 for more information about places to cool off.
Late-Week Storm Chance
The pattern is expected to shift late in the week. Scattered showers and thunderstorms are possible Friday into the weekend, with Friday’s high still forecast near 97°F and a higher chance of storms later in the day. Any storms that do fire could bring heavy downpours and brief gusty winds, which could complicate outdoor Fourth of July setup and early celebrations.
Residents planning holiday events should keep an eye on updates and any additional advisories from the National Weather Service Detroit as the week goes on.
