Detroit is waking up to clear skies, sticky air and a fast climb toward summerlike heat. Around 5:35 a.m. Tuesday, temperatures were near 75 degrees with humidity above 80%, and a few showers or thunderstorms could pass through before 9 a.m. After that, skies should turn mostly sunny, with an afternoon high near 92 and heat index values reaching 100.
The latest outlook is a meaningful update from Hoodline's previous Detroit forecast, which called for slightly lower temperatures and less-defined storm chances. The National Weather Service Detroit/Pontiac office now says storms that form Tuesday or Wednesday could bring damaging winds, hail, heavy downpours and localized flooding.
Afternoon Heat Builds After A Quiet Morning
Most of Tuesday afternoon should stay dry, with west-southwest winds between 5 and 8 mph and temperatures rising through the 80s. Storm chances increase again late in the afternoon and into the evening, though the exact location and timing remain uncertain. Any storm that develops could intensify quickly in the hot, humid air.
Wednesday Keeps Detroit Hot And Unsettled
Wednesday may be the hotter of the two days, with a high near 93 and heat index values as high as 101. Showers and thunderstorms have a 40% chance during the day, with gusts up to 18 mph possible, while storm odds rise to 60% Wednesday night. The main concerns are strong winds, hail, and brief heavy rain rather than all-day rainfall.
Cooler Air Arrives Before Labor Day
Rain and thunderstorm chances remain elevated Thursday, when showers are likely early, and another round of storms could develop during the afternoon. Temperatures ease to around 88 degrees Thursday, then fall to the mid-80s Friday, low 80s Saturday and Sunday, and about 80 on Labor Day. Slight shower chances linger into the holiday, but the cooler temperatures should make outdoor plans more manageable.
There are no watches, warnings, or advisories posted for Detroit in the current forecast. Still, anyone spending time outside Tuesday or Wednesday should drink plenty of water, take breaks from the heat, and head indoors as soon as thunder is heard.
