Columbus, Ohio – Ohioans from Toledo to Cincinnati should prepare for a dangerous stretch of extreme heat beginning Sunday afternoon, with heat index values possibly climbing as high as 104°F and little overnight relief through Tuesday.
According to the National Weather Service offices in Cleveland and Wilmington, an Extreme Heat Watch is in effect from Sunday at 12 p.m. through Tuesday at 8 p.m., impacting nearly every corner of the state as well as parts of Indiana, Kentucky, and Pennsylvania. Cities including Cleveland, Akron, Columbus, Dayton, Cincinnati, and Youngstown are all expected to experience prolonged high temperatures and humidity, with potential heat-related illnesses on the rise.
High heat combined with elevated humidity will make conditions especially hazardous for outdoor workers, children, the elderly, and those without reliable air conditioning. Overnight lows are expected to stay in the mid-70s, preventing the body from cooling down properly.
In Cuyahoga, Franklin, Hamilton, and surrounding counties, cooling centers may be activated, and officials urge residents to stay hydrated, limit outdoor activity, and check on vulnerable neighbors. Public utilities recommend limiting high-energy usage during peak hours.
This marks the first significant heat event of the summer for much of Ohio. The heat may extend into Wednesday, with updated advisories expected.
