Highs of 90 and above predicted for weekend
It's going to be a scorcher all weekend with temperatures predicted to be up to 17 degrees above average through Sunday.
The National Weather Service has issued an excessive heat watch for Saturday, where temperatures in the region are expected to reach a record-breaking high of 97 degrees. With increasing humidity, the agency predicts the heat index will feel around 105 degrees.
"The main driver for the heat wave this weekend is a strong ridge of high pressure that is to our south," said Jordan Dale,a meteorologist with the National Weather Service in White Lake Township office. "It'll be building into the region. That'll allow southerly flow to push that heat and moisture north into the Great Lakes region."
The record high for June 30 is 96 degrees set in 1931 and the record low is 47 degrees set in 1943, according to the weather services' records. The average temperature for June in Detroit is 79.3 degrees.
The weather service said it expects to issue a region-wide heat advisory on Saturday and Sunday.
An ozone action day advisory issued by the Michigan Department of Environmental Quality will remain in place throughout Saturday in Livingston, Macomb, Monroe, Oakland, St. Clair, Washtenaw and Wayne counties.
Because of elevated ozone levels, people in those counties are asked to refrain from refueling vehicles or topping off when refueling, using gasoline-powered lawn equipment and using charcoal lighter fluid. High ozone levels can affect people with respiratory diseases, such as asthma.
Sunday is expected to reach a high of 95 and feel closer to 100. But the heat, weather officials said, will be tempered by increasing chances for scattered thunderstorms as a cold front approaches the region from the west.
"We might get some relief late Sunday," Dale said. "As we head into Monday, a cold front will push through. We should cool off some on Monday."
The City of Detroit will open six recreation centers Saturday and Sunday to give residents relief from the extreme heat. The cooling centers: Williams Recreation Center, Coleman A. Young Recreation Center, Farewell Recreation Center, Crowell Recreation Center and Northwest Activities Center will be open noon to 8 p.m.
According to SYNERGY HomeCare, a local senior assisted living company, heat when combined with certain medications can be dangerous for seniors. Seniors who take antidepressants, antihistamines, beta-blockers, amphetamines, diuretics or sedatives should be cautious with high heat and stay hydrated.
