Cincinnati, Ohio – An extended stretch of dangerous heat will blanket parts of Ohio, Kentucky, and Indiana beginning Sunday afternoon, with heat index values soaring as high as 103 degrees through Tuesday evening.
According to the National Weather Service in Wilmington, a Heat Advisory remains in effect from noon Sunday through 8 p.m. Tuesday for central and southwest Ohio, northern Kentucky, and southeast Indiana. The advisory covers major cities including Cincinnati, Columbus, Dayton, Lexington, and Richmond.
The combination of high humidity and temperatures in the mid-90s will push heat index readings into the triple digits, significantly increasing the risk of heat-related illnesses, particularly for outdoor workers, seniors, and young children.
Residents in affected areas are urged to: Stay hydrated and avoid outdoor activity during peak heat hours (1–6 p.m.). Seek air-conditioned spaces when possible. Wear light, loose-fitting clothing. Check on elderly neighbors and those without cooling.
Urban centers like Columbus and Cincinnati may face additional strain on cooling shelters and utility services, especially during afternoon hours. This advisory marks one of the region’s earliest prolonged heat events in recent years.
Warnings remain in effect through Tuesday at 8 p.m., with updates expected if conditions worsen or expand.
