Cloudy and cool early today in Detroit, with readings near 37°F and a steady gray sky, but warmer air is on the way. Temperatures will climb into the low 60s as a push of mild air rolls in and drags a shield of rain across the region. Showers are expected through the morning commute and into the afternoon, with a few rumbles of thunder in the mix. The main concern arrives tonight until early tomorrow, when a gusty line of storms could bring damaging wind to parts of the area, especially west of US 23.
What To Expect Thursday
According to NWS Detroit, rain is likely before 8 a.m., followed by rain with a slight chance of thunderstorms between 8 a.m. and mid-afternoon. Most spots should top out near 61°F before slipping back into the mid 50s later in the day.
East southeast winds around 10 to 12 mph will occasionally gust into the 20 mph range, which, combined with heavier bursts of rain, will make for slick roads and reduced visibility at times. New rainfall amounts are expected to stay mostly under about a half inch, although localized heavier downpours are possible where showers repeatedly track over the same areas.
Flooding And Rain Totals
The Weather Prediction Center has placed parts of Southeast Michigan under a marginal risk for excessive rainfall, meaning repeated showers could trigger brief urban or poor drainage flooding. Per WPC, most of the region is expected to pick up a few tenths of an inch of rain, with isolated pockets approaching an inch over the next 48 hours.
Drivers and residents should keep an eye on low-lying areas, storm drains and spots that typically collect water after heavier bursts of rain, especially during the busier drive times.
Tonight's Threat And Marine Impacts
NWS forecasters say additional rounds of showers and thunderstorms are likely this evening and overnight. The best chance for strong to severe storms is west of US 23, where damaging straight-line winds are the primary concern. Isolated gusts could reach roughly 60 mph in the strongest cells.
On the water, mariners on Lake Huron and Saginaw Bay should expect elevated waves and gusty onshore winds. Small Craft Advisories remain in effect for portions of the northern waters into Friday. Storms should generally weaken as they slide east, but sudden gusts, lightning and brief heavy downpours are still possible wherever individual cells track.
Commute Tips
For the morning drive, allow extra time on wet roads and watch closely for standing water, especially near on- and off-ramps and in underpasses. This evening, anyone west of US 23 may want to rethink outdoor plans or at least have a solid backup indoors.
If you are heading out on the water, secure loose gear, wear a life jacket and check the latest marine forecasts before leaving the dock. Conditions may deteriorate quickly near stronger storms.
