Cleveland, Ohio – Scorching heat and stagnant air could turn Sunday into a health risk across northeast Ohio, especially for those traveling along I-90 and I-271. The National Weather Service warns of heat index values climbing into the mid-90s, paired with an Air Quality Advisory for ground-level ozone through midnight Sunday.
According to the Northeast Ohio Areawide Coordinating Agency, air will be unhealthy for sensitive groups in counties including Cuyahoga, Lorain, Lake, Medina, Portage, and Summit. Those with asthma or heart conditions, as well as children and the elderly, are urged to limit time outdoors. Residents should avoid mowing lawns, refueling in the heat of the day, and consider delaying non-essential travel, especially along congested roadways.
High pressure building across the region will keep skies mostly sunny, but air stagnation will trap pollutants near the surface. Cleveland, Akron, and surrounding cities should expect hot, hazy conditions into Sunday night, with slightly cooler relief expected Monday.
This heat follows Saturday’s comfortable conditions but marks the beginning of a hotter stretch that will linger through midweek. Northern Ohio will remain under summer-weather stress with climbing temperatures and limited wind.
