Columbus woke up to a wall of rain and thick fog on Wednesday, May 27, 2026, with temperatures hovering around 68°F and visibility down to roughly 3 miles near John Glenn Columbus International Airport. Humidity is running very high, and steady showers are already slowing the morning commute across the metro.
Flood Watch And Rain Totals
A Flood Watch is in effect through late tonight, and forecasters say widespread rainfall totals of 1 to 2 inches are possible, with locally higher amounts where downpours repeat over the same spots. According to the National Weather Service Wilmington, a few rounds of heavy rain could trigger rapid runoff and brief flash flooding in low-lying and poorly drained areas.
Timing And Impacts
The steadiest, heaviest rain is most likely this morning into the mid-afternoon, with showers and embedded thunderstorms becoming more scattered after about 5 p.m. Forecasters note the axis of heaviest rainfall may set up near the I-70 corridor, so neighborhoods along that route should watch for ponding and temporary street flooding.

Commute And Safety
Drivers should slow down on wet roads, leave extra braking distance, and avoid driving through standing water, since just a few inches can stall a car or sweep it off the roadway. Anyone in the watch area should keep an eye on updates and be ready to act quickly if a flash flood warning is issued for their neighborhood.
Thursday And Beyond
Conditions clear quickly after the watch ends. Thursday is forecast to be sunny with a high near 77°F, and an extended stretch of mainly dry weather is expected into early next week. If you have outdoor plans later this week, expect warmer, sunnier conditions and a much lower chance of rain.
