Motor City Braces For Rush-Hour Soaker And Wild Winds

Detroit started today, mostly cloudy and sitting around 72°F, and the atmosphere is gearing up for a messier afternoon. Showers are already building across the region, with a line of thunderstorms expected to roll through later in the day. Highs should top out near 85°F before sliding back into the low 80s, and the strongest storms may bring heavy downpours and gusty winds. The soggiest stretch is expected during the afternoon commute and into the evening, when localized street flooding and sharply reduced visibility are most likely.

Afternoon Storms And Flood Risk

Showers and thunderstorms are likely this afternoon, with forecasters calling for roughly a 90% chance of precipitation and gusts that could reach about 22 mph. New rainfall amounts of 0.5 to 0.75 inches are expected, with isolated pockets picking up 1 to 2 inches. According to the National Weather Service Detroit, convective rain rates may briefly hit around an inch per hour, which can trigger urban flash flooding if storms repeatedly track over the same neighborhoods. Anyone with outdoor plans should be ready to move things inside quickly and plan on slower or disrupted travel when the heavier downpours roll through.

Evening Commute And Tonight

Storms should gradually wind down late tonight, but scattered showers and a chance of additional thunderstorms may linger through about midnight. Overnight lows will hover near 68 to 70°F, with southwest winds easing to around 6 to 10 mph. Most spots that stay active into the night are expected to see lighter totals, mainly a few tenths of an inch of additional rain, although localized heavier pockets remain possible earlier in the evening.

Heat Returns Wednesday And Thursday

After this round of rain, heat and humidity are set to make a quick comeback on Wednesday and Thursday. Highs will climb into the low 90s, with heat index values pushing close to 100°F, which will make outdoor work and exercise feel pretty rough. The forecast discussion notes that a Heat Advisory could be necessary if the combination of humidity and temperatures holds. Residents who are sensitive to heat can find daytime relief at the City of Detroit cooling centers.

Quick Safety Tips

Plan on extra travel time this afternoon, keep an umbrella or rain jacket handy, and avoid driving through standing water. Turn around, don’t drown. Check the radar before you head out and move outdoor plans indoors if storms are nearby. If you come across a flooded road, find another route. During the midweek heat, drink plenty of water, limit strenuous outdoor activity during the hottest part of the day, and use cooling centers if you do not have reliable air conditioning at home.
