It’s going to be a dangerously hot week in metro Detroit and elsewhere in Michigan, with record-breaking temperatures of up to 100 degrees and heat index values soaring well above that.
The hot and humid conditions will arrive on Monday, June 29, according to a June 28 post on X by the National Weather Service’s office in White Lake. The hottest conditions are expected Tuesday, June 30, through Thursday, July 2, “with potential for highs to reach 100 degrees and heat indices in excess of 105 degrees,” the post said.
The National Weather Service said there will be little nighttime relief, with lows only dropping to the mid 70s.
The heat index forecast — what the temperature feels like to the human body — shows temperatures reaching 108 degrees in Ann Arbor on June 30 and July 1. The heat index shows Detroit reaching 106 degrees on those days, while Pontiac’s heat index is expected to reach 107 degrees.
AccuWeather says the expected high temperature of 99 degrees in Detroit on Tuesday, June 30, will break the record of 96 degrees last reached in 1931. The weather forecast for Detroit shows temperatures cooling slightly over the holiday weekend, with an expected high of 93 degrees on Friday, July 3, 92 degrees on Saturday, July 4 and 90 degrees on Sunday, July 5.
Those headed out of town this week for the July 4 holiday likely won’t find much relief from the hot and humid conditions. Many areas in the Midwest and eastern U.S. will see well-above-normal and possibly record-breaking temperatures, according to reporting from USA TODAY.
Temperatures are going to be “well above normal across much of the Central and Eastern U.S.,” said Frank Pereira, a meteorologist at the Weather Prediction Center, part of the National Weather Service.
The Rockies and the Northwest, however, will likely see well below-normal temperatures and possibly some high-elevation snow in the Northern Rockies.
East of the Rockies “things are going to be quite toasty and well above normal through next week, and really starting to ramp up in the Eastern U.S. as we get into the middle of next week,” Pereira told USA TODAY on June 26.
On June 30 and July 1, “we’ll start to see records fall from the Ohio Valley into the mid-Atlantic and Northeast,” he said. “By Thursday, (July 2), we’ll be looking at temperatures in the triple digits from the Carolinas northward up through the mid-Atlantic, including D.C.”
From the Dakotas and eastward, expect temperatures in the upper 90s with humidity that will make it seem closer to 110 degrees, he said.
When overnight lows remain so warm, it makes it harder for streets, lawns and buildings to cool off, and increases the dangers for heat-related illnesses, especially for the elderly and those who may not have adequate cooling systems.
Safety tips for high temperatures
The National Weather Service in White Lake said the heat and humidity will present hazardous conditions for those participating in outdoor activities and for those who don’t have access to air conditioning.
