Metro Detroit forecast: Storms, cooler air, more heat

Anyone tired of the hot, humid days gripping Metro Detroit recently will find relief — briefly — to end the work week.

A weak cold front pushing into southeast Michigan is sparking a chance of showers and thunderstorms Thursday, said Heather Orow, a meteorologist with the National Weather Service station in White Lake Township.

The thermometer could still reach the mid-80s, but after that, “we have an area of high pressure that’s going to be building over the northern Great Lakes,” Orow said. “That’ll keep the temperatures closer to normal and the weather quiet.”

The weather service forecasts highs in the lower 80s — right around average for this time of the season — on Friday, Saturday and Sunday, under mostly sunny skies. Overnight lows should drop into the 60s.

Not only that, “the humidity will be lower than it has been over the last week or two,” Orow said. “We’ve had a lot of not just warm days but humid days.”

This month, Detroit Metro Airport has reported nine 90-degree days, Orow said.

Wednesday’s high of 92 was the latest and a full nine degrees above average, weather service data shows.

The July hot stretch also notched the highest reading of 2016 so far: the 98 degrees on Saturday tied the record for the date previously set four years earlier and in 1933, according to the weather service.

That sort of warmth isn’t on the horizon, but after the short cool-down this weekend, Metro Detroiters should still see more heat.

“We’re going to start warming up next week,” Orow said. “We’re going to get up back into the upper 80s to around 90. We’re going to start bringing the humidity back up.”
