Cincinnati is waking up Thursday to patchy fog and muggy air before the city turns sunny, scorching and dangerously hot. The high is expected to reach 98 degrees, with the heat index climbing as high as 107.
A Heat Advisory remains in effect through 8 p.m. Friday, according to the National Weather Service. The combination of heat and humidity could raise the risk of heat illness, particularly for people working or exercising outside.
Fog Burns Off Before Afternoon Heat Peaks
Patchy fog should lift by about 9 a.m., giving way to mostly sunny skies through the afternoon. Winds will stay light from the southwest and west at roughly 1 to 6 mph, offering little relief as temperatures climb through the 80s and 90s.
Thursday night will remain mostly clear, but the low near 75 will not provide much of a reset; the overnight heat index could still reach 104. Friday will be nearly as hot, with a high near 97 and another heat index peak around 107.
Storm Chances Rise Before A Cooler Weekend
Cincinnati's rain chances stay very low Thursday and Friday, but the broader regional forecast keeps thunderstorm activity possible late Thursday through Saturday. For the city, the chance reaches about 20% Friday night after 2 a.m. and 40% Saturday, when showers and storms could bring less than a tenth of an inch of rain.
Saturday should be cooler but still warm, with a mostly sunny high near 92. Sunday brings the first real break, with sunshine, a high near 85 and an overnight low around 64; Labor Day should stay sunny near 87 before temperatures reach 86 to 88 degrees Tuesday and 89 to 91 degrees Wednesday.
The latest outlook is a substantive update from Hoodline's earlier forecast, which focused on the heat through Thursday rather than the extended advisory and weekend cooldown now in view.
Heat Safety Remains The Priority
According to the City of Cincinnati, all Cincinnati Recreation Commissions locations are open as cooling centers during periods of extreme heat in the summer. According to the City of Cincinnati's Urban Heat page, Cincinnati Recreation Centers were designated as cooling centers for residents during increased heat advisories in the summer of 2023.
The National Weather Service advises drinking plenty of fluids, staying in air conditioning when possible, avoiding prolonged sun exposure and checking on relatives and neighbors. Anyone planning outdoor work or exercise should move it to the morning or evening, take frequent breaks and leave immediately if they begin feeling overheated.
