4Warn Weather – Temperatures are taking a step back toward reality across Metro Detroit after heat revved up this week, but the tradeoff is a stretch of comfortable, low-humidity weather that should make for a beautiful run into the weekend and the Chevrolet Detroit Grand Prix.
A weak backdoor cold front sliding through the region Wednesday night may spark a couple of isolated showers, mainly south of M-59 and closer to the Ohio border, but many neighborhoods are expected to stay dry.
Any showers that develop will fade quickly after sunset as cooler, drier air settles into the area overnight.
Thursday
By Thursday, Southeast Michigan will feel noticeably different compared to the 80s this week.
Afternoon temperatures will top out mainly in the lower to mid-70s, much closer to the late-May average high of around 75 degrees.
Areas near Lake Huron could stay even cooler, with highs around 60 degrees in Port Huron and mid-60s in parts of the Thumb, thanks to a northeast breeze coming off the chilly water.
The cooler air will come with sunshine, lower humidity, and a refreshing feel that many people may find ideal for outdoor plans.
It will be a great day to mow the lawn, take a walk or bike ride, sit outside at a restaurant, or spend time on the water.
Boaters should still keep in mind that northeast winds may occasionally gust near 20 mph, especially near the lakeshore, creating choppier conditions on Lake Huron and parts of Lake St. Clair.
Thursday
Even though temperatures will be cooler on Thursday, the late-May sun remains strong.
UV levels are climbing this time of year, and it does not take long to get too much sun exposure, especially with extended time outdoors.
Sunglasses, sunscreen, and hydration are still important, even on a mild day.
Friday
The comfortable pattern continues into the weekend as Detroit prepares to welcome crowds downtown for the Chevrolet Detroit Grand Prix beginning Friday.
Temperatures are expected to warm back to near 80 degrees on Friday, with sunshine and dry weather, making for excellent conditions for the race festivities, outdoor dining, concerts, and riverfront activities.
Saturday and Sunday
Saturday cools slightly back into the lower 70s before temperatures rebound into the upper 70s Sunday and early next week.
Right now, the forecast looks largely dry through the weekend with only a chance of a stray shower arriving late Sunday night into Monday morning.
Sunset times
The extended daylight is also becoming more noticeable. Sunset in Metro Detroit is now approaching the 9 p.m. mark, with Wednesday night’s official sunset time at Detroit Metro Airport at 8:59 p.m.
The region is nearing its latest sunsets of the year, which occur in late June and early July at 9:13 p.m.
