A heat wave is expected to smother Michigan by Thursday, July 24, with temperatures in the mid 90s and the heat index topping 100 degrees.
“Pleasant weather today before the heat and humidity dominates the picture once again by Wednesday,” the National Weather Service office for Northern Indiana said on X Tuesday. “The combination of heat and humidity will cause it to feel like 98-102+ degrees in northwest Indiana and far southwest Michigan.”

In Lansing, on July 24, officials forecast a high of 95 degrees, with the remainder of the week lingering in the 80s to lower 90s.
“Thursday (July 24) remains on track to be the hottest day of the week; a heat advisory will likely be needed as the heat index reaches 100+ degrees,” NWS in Detroit said. “Scattered-numerous showers and storms then move in Thursday evening/night.”
The city of Lansing said it activated its “code red” heat protocols and announced several cooling centers. The policy will be in effect on Wednesday, July 23, and Thursday, July 24, from 8 a.m. through 8 p.m. each day.
Residents are advised to stay hydrated and avoid lengthy sun exposure to avoid deadly heat-related illnesses, such as, heat exhaustion or heat stroke.
“Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors,” the NWS said.
Heat advisories have been issued for southwest Michigan, including Berrien and Cass counties. More heat warnings are expected in Michigan as the warm air moves north and east.
“A mid to upper level high centered over the Lower Mississippi Valley will be expanding northeastward over the next few days, bringing a widespread heat wave from the Mississippi Valley, into the Ohio Valley and Great Lakes and eventually into the East over the next few days,” the National Weather Service said.
“There are (as of Tuesday) over 80 million people under either an Extreme Heat Warning, Extreme Heat Watch or Heat Advisory from the Southeast, North Florida, the Florida Panhandle, the Central Gulf Coast and northward through the Lower to Middle Mississippi Valley, Lower Tennessee and Lower Ohio Valley regions,” the NWS said. “These numbers will likely increase over the next few days as the heat wave expands northeastward and then eastward.”
The weather agency said the Great Lakes region could see record high morning “low” temperatures this week.
