Columbus, Ohio – Heavy rain and dangerous thunderstorms are set to drench Central Ohio starting Wednesday, with repeated storms threatening flash flooding through early next week. Drivers on I-70 and residents across Franklin County should be prepared for road delays, power outages, and quickly changing conditions as the state braces for an extended period of unsettled summer weather.
According to the National Weather Service, several rounds of showers and storms will sweep through Columbus and surrounding areas from Wednesday, July 16, straight through Monday, July 21. Flash flooding remains the biggest concern, with multiple rain episodes expected to saturate local roads and low-lying neighborhoods. Meteorologists warn that rainfall totals may exceed an inch in some areas, and brief downpours could create dangerous ponding on major highways and city streets.
On Wednesday, storms will begin mid-morning and intensify in the afternoon, with a 70% chance of rain and a high near 88°F. Thursday will see more storms likely, especially after 2 p.m., with temperatures reaching 91°F and rain chances holding at 80%. Even Friday’s brief sun will be interrupted by more afternoon showers and a risk for isolated thunderstorms. The pattern of showers and storms will linger into the weekend, so outdoor plans may need to be flexible.
Residents should avoid driving through flooded roads, monitor local alerts, and keep flashlights and backup chargers ready. Spotter activation is not expected as of Tuesday evening, but that could change if flooding intensifies.
Warnings are expected to remain in effect through Monday, with the National Weather Service providing frequent updates.
