Metro Detroit is in for a stretch of late-summer heat before storms and cooler air move in by the holiday weekend, forecasters say.
Monday's temperatures should top out in the upper 80s with scattered showers and thunderstorms possible through the evening amid humid conditions, according to the National Weather Service.
The heat builds Tuesday as temperatures are predicted to get to the low 90s under mostly sunny skies. AccuWeather predicts a potential afternoon thunderstorm.
A robust low-pressure system over northern North Dakota and the Canadian prairies drawing heat and humidity from the Central Plains and Mississippi River Valley up into the Great Lakes is generating precipitation and heat.
"On a climatological normal, it's above average. Typically the high for Detroit this time of year is right around 79 to 80, so we'll be potentially 5 to 10 degrees above that," said Kyle Klein, a meteorologist at the National Weather Service Detroit office.
Wednesday will peak as one of the hottest days this week with temperatures in the 90s. A thunderstorm is also expected.
While that's far from normal, it is far from the record high of 100 set on Sept. 2, 1953, according to National Weather Service records.
"Ever so often we have this late August, September heat wave," Klein said.
The heat breaks Thursday behind the storms, with highs falling into the mid- to upper 80s and a continued chance of showers, according to both services.
By Friday, temperatures are expected to cool further with highs in the low 80s with a mix of cloudy and sunny skies, according to weather outlets.
Both services forecast sunny and comfortable conditions Saturday and Sunday with highs in the upper 70s to low 80s and little to no chance of rain.
