August, on pace for record heat, faces cooldown
Warmer-than-normal temperatures this month have Metro Detroit poised to beat a 21-year record for the hottest August.
That could be short-lived, however, if the area has an expected cool-down early next week, said Steve Considine, meteorologist with the National Weather Service in White Lake Township.
The average August temperature for Detroit this month is 78.5, up from the 72.7 degree average normally seen by this point of the month, according to the weather service. The hottest August on record was 77.1 degrees in 1995.
“Right now, while we’re on pace to beat the 1995 record, next week looks to be considerably cooler,” Considine said. “I don’t think, given the forecast temperatures, we’re going to beat the warmest August on record.”
The first half of August has been unusually warm due to an upper level ridge that creates a dome of warmer air over the eastern United States, Considine said. This helps holds the cooler air north in Canada.
That’s expected to change next week.
“We’re having a pretty strong cold front come through Saturday night,” Considine said. “We’re displacing the upper level ridge to the south and east. We’re going to get some northwest flow bringing cooler air from Canada down into the Great Lakes.”
The rest of the week will be warm with highs expected in the mid 80s on Friday and Saturday.
On Sunday, temperatures are expected to drop below average with highs expected in the mid-70s on Sunday and Monday and in the upper 70s on Tuesday.
