Columbus is starting the day in a sticky soup, with morning temperatures sitting in the mid-70s and dew points in the low 70s. That muggy air will help fuel showers and thunderstorms this afternoon as the heat pushes toward 90°F. A few storms could turn strong to severe, bringing damaging wind and locally heavy downpours.

When Storms Will Move In

Spotty showers are on the table through the morning, but the main event is expected this afternoon into the early evening. Forecasters are calling for around a 70 percent chance of rain, with the most widespread and intense storms likely between about 3 p.m. and 7 p.m.

Southwest winds of 6 to 14 mph will flip to the northwest behind a cold front this evening, and that shift could come with some gusty punch as storms roll through. Meteorologists at the National Weather Service expect most neighborhoods to pick up only a few tenths of an inch of rain, but brief heavier pockets are possible where the stronger cells set up.

Impacts For Commuters And Outdoor Plans

Plan on quick-hitting downpours, frequent lightning and gusty winds that could slow the afternoon commute, knock visibility down in a hurry and send outdoor events scrambling for cover. If you are heading out this afternoon or evening, pack rain gear, build in extra travel time and steer clear of standing water on the roads.

Anyone running games, festivals or other outdoor gatherings should have a solid shelter plan ready and keep a close eye on conditions during the peak storm window.

Heat And Where To Cool Off

Before storms fire up, the combo of heat and humidity will make it feel like the mid to upper 90s. For anyone without reliable air conditioning, that kind of steam can catch up fast.

The city has cooling options available across community centers, libraries and pools. You can search for nearby locations or call 311 if you need help finding a cool place. Details and locations are listed on the City of Columbus 311 page.

Looking Ahead

Storm chances fade overnight into tomorrow, which should be mostly sunny with highs in the mid-80s. Another cold front slides in on Tuesday, bringing a renewed shot at thunderstorms and the potential for additional strong storms.

Behind that system, a somewhat cooler air mass settles in for the middle and latter part of next week, with highs easing back into the upper 70s and low 80s. Keep an eye on updated forecasts as you map out plans for the next several days.
