Cloudy, muggy air is already draped over Columbus on Wednesday, June 10, 2026, with temperatures around 75°F at John Glenn Columbus International this morning and a much hotter afternoon on the way. A round of scattered showers and thunderstorms is possible both before and after midday, while parts of west-central Ohio sit under a Heat Advisory from noon to 8 p.m.
The Heat Advisory covers Auglaize, Hardin, and Mercer counties from noon to 8 p.m., with heat index values expected to push near 100°F. Officials urge residents to stay hydrated, limit strenuous outdoor work, and check in on anyone especially vulnerable to the heat. According to the National Weather Service, a combination of hot, humid air and afternoon sunshine will make it feel hotter than the thermometer suggests.
Afternoon Heat And Storms
High temperatures should climb to around 90°F across the metro, with southwest winds around 7–12 mph. Sticky humidity will push heat index readings into the mid 90s for many neighborhoods. Scattered showers and storms, roughly a 30–40% chance, could bring brief heavy downpours and gusty winds that may slow the evening commute.

Timing And Commute Tips
Any early morning showers should fade by mid-morning, but new storms may pop back up in the late morning and afternoon. That means on-and-off wet pavement and slower traffic wherever the heavier showers track. If you hit standing water, remember the old line “turn around, don’t drown,” and steer clear of any storm-damaged trees, limbs, or other debris in the road.
Where To Cool Off
If you do not have dependable air conditioning, note that Columbus Recreation and Parks has opened community centers as cooling options during past heat events, including sites like Driving Park and Dodge community centers.
