Wilmington, Ohio – Ohio residents are facing a dangerous blast of summer heat Thursday, with heat indices soaring past 105°F in Dayton, Cincinnati, and several surrounding cities. Drivers, workers, and families should prepare for potentially hazardous conditions from 8 a.m. through at least 8 p.m.
According to the National Weather Service in Wilmington, a hot and humid air mass will push apparent temperatures above 100°F across much of southwest and central Ohio. Cities including Dayton (106°F), Cincinnati (105°F), and Columbus (100°F) will experience the most severe impacts, with excessive heat stretching into Sidney, Wilmington, and even Portsmouth.
Local agencies urge residents to stay hydrated, limit outdoor activities, and never leave children or pets unattended in vehicles. The heat index could spike high enough to threaten vulnerable groups—especially the elderly and those without air conditioning. Schools, job sites, and public events may see schedule changes or closures, and utility usage is expected to surge. Workers are encouraged to take frequent shade breaks, and all Ohioans should check on neighbors who may need assistance.
While a slight chance of storms exists Thursday afternoon, heat is the main threat. The NWS warns that this kind of weather can cause rapid dehydration and heat-related illnesses if precautions aren’t taken.
