Detroit is waking up to clear skies and temperatures around 63 degrees Wednesday morning, but the calm start will not last. The city could reach 74 degrees before rain chances rise late in the day and turn into a wetter, cooler stretch by Friday.

Showers Arrive Wednesday Night

Wednesday should stay mostly cloudy and mild, with south-southwest winds around 6 to 9 mph and only a slight chance of showers after 5 p.m. Rain becomes more likely after 7 p.m., with an 80% chance of showers Wednesday night and a low near 63.

Thursday will be warmer and noticeably muggier, with a high near 76 and a 50% chance of showers during the day. The National Weather Service Detroit/Pontiac expects the rain to become more persistent Thursday night, when the chance rises to 100% and rainfall could total between a half-inch and three-quarters of an inch.

Heaviest Rain Threat Runs Into Friday

The broader Thursday afternoon-through-Friday morning period could bring roughly 0.5 to 1.5 inches of rain, according to the National Weather Service Detroit/Pontiac. Some locations could receive more than 2 inches if steadier rain sets up, creating at least a chance of minor flooding, especially in areas that see repeated downpours.

Friday stays wet early, with showers likely before 2 p.m. and a much cooler high near 66. No watches or warnings are listed for Detroit, but commuters and anyone with outdoor plans should be ready for slick roads and reduced visibility during the morning rain.

Clearer, Cooler Weekend Ahead

The forecast turns more cooperative Friday night, when skies should clear and temperatures fall to around 47. Saturday looks sunny with a high near 64, followed by a mostly sunny Sunday near 67.

That sharper shift from a warm, humid Thursday to a cool and dry weekend is a substantive change from Hoodline's earlier Detroit forecast, which had described a shorter-lived midweek shower chance. Monday brings more sunshine but a cooler high near 59, with another chilly low around 40 Monday night.
