Columbus, Ohio – A stifling heat wave arrives Thursday, July 24th, putting Columbus residents at risk as heat index values near 100 degrees. Roads like I-70, I-71, and I-270 will be baking by midday, making travel hazardous and increasing the threat of heat-related illness. Those without air conditioning or outdoor workers should prepare now, as the National Weather Service warns that this intense heat could linger well into the weekend.
According to the National Weather Service in Wilmington, a Heat Advisory remains in effect from 11 a.m. to 8 p.m. Thursday. Highs will reach 94°F in Columbus, but it will feel closer to 103°F during peak afternoon hours. Air quality alerts also remain in place for Central Ohio, including Delaware, Fairfield, and Franklin counties, until midnight Thursday due to elevated ozone levels. Sensitive groups and those with respiratory issues are urged to limit time outside, especially during the hottest part of the day.
High humidity, intense sunshine, and stagnant air will make it dangerous for anyone spending extended time outdoors. City health officials urge residents to drink plenty of water, seek air-conditioned spaces, and check on neighbors or the elderly. Avoid strenuous activity between noon and 6 p.m., and never leave children or pets in vehicles. If you must travel on major highways like I-70 or I-71, plan for frequent breaks and carry water.
Relief is limited as storms are only a slight risk Thursday night, but a better chance for showers and thunderstorms returns Friday afternoon and again late Saturday. Rainfall may be heavy at times, leading to brief ponding on roadways and isolated power outages.
What’s next?
Friday and Saturday will remain warm and humid, with highs in the upper 80s to near 90°F, and thunderstorms likely both afternoons. A gradual cooldown is expected Sunday into early next week as drier air moves in, bringing overnight lows back to the low 70s. The threat of heat illness persists, so continue following safety tips through the weekend.
