Columbus, Ohio – A dangerous stretch of heat is bearing down on Ohio, with triple-digit heat index values expected across much of the state starting Sunday afternoon.
According to the National Weather Service in Wilmington, an Excessive Heat Watch is in effect from 12 p.m. Sunday, June 22, through 8 p.m. Tuesday, June 24. Heat index values could peak at 105°F, especially in cities like Columbus, Dayton, and Cincinnati. The warning covers much of central, southwest, and west-central Ohio, including Franklin, Greene, Butler, and Pickaway Counties.
Drivers along I-70 and I-71 should be alert: rising pavement temperatures can cause tire blowouts and stress engines. Residents are urged to stay indoors during peak afternoon hours, drink fluids, and avoid strenuous activity. The lack of overnight cooling will add extra stress to vulnerable populations.
Saturday will be sunny with a high near 90°F, but the real intensity begins Sunday. Columbus, Dayton, and surrounding areas will feel like they’re in a sauna, with sunny skies and highs of 96°F both Sunday and Monday.
Nighttime lows in the mid-70s will offer little relief, especially in areas without air conditioning. Emergency managers recommend checking on elderly neighbors and limiting outdoor exposure.
The heat dome could linger, and the NWS says conditions may remain hazardous through Wednesday. More alerts may follow.
