Detroit started this morning under mostly cloudy skies with temperatures around 72 degrees, and the muggy air is setting the stage for a wet, stormy afternoon. Rain chances rise through the morning before showers and thunderstorms become most likely after 2 p.m., with a high near 83.

The National Weather Service Detroit/Pontiac forecast calls for a 70% chance of precipitation today and southwest winds of 7 to 14 mph, with gusts up to 24 mph. Rainfall totals are expected around a tenth to a quarter inch, though a heavier downpour could still make roads slick and visibility briefly messy.

Storm Window Arrives After Lunch

Scattered showers may pop up between 8 a.m. and 2 p.m. before thunderstorms become more likely in the afternoon. The strongest storms may bring gusty winds, and the weather service notes heavy rain could develop if cells linger over the same neighborhoods.

The timing is a notable shift from Hoodline’s forecast yesterday, which had put the day’s high closer to 87 and left the storm window less defined. The latest update trims the high and sharpens the afternoon threat.

Cooler, Drier Air Takes Over

Showers and storms should taper before 7 p.m., and tonight drops to around 66 degrees under partly cloudy skies. Thursday stays mostly cloudy near 78, then Friday turns sunny near 78, with cooler mornings in the upper 50s.

Weekend Warm-Up Returns

Saturday climbs back to about 83 under mostly sunny skies, with only a slight shower chance late Saturday night. Next Sunday remains warm near 82, while another slight shower chance appears next Monday, and storm chances tick back up next Monday night into next Tuesday.

For commuters, the practical move is to keep extra time for the afternoon and avoid flooded or ponded roads. No watches or warnings are posted for Detroit in the current forecast, but thunder can arrive quickly once the front moves through.
