Columbus is starting Tuesday, May 26, 2026, on a deceptively calm note. Early this morning, skies were mostly clear, temperatures were in the low 60s at John Glenn Columbus International, and winds were light but the air was sticky. That quiet setup will not last long, with scattered showers and a few thunderstorms on tap for the afternoon and a soaking rain likely late Tuesday night into Wednesday, May 27.
What To Expect
Afternoon highs are expected to climb into the low 80s across the metro, but by late day, around 4 to 5 p.m., a slight chance of storms could bring brief downpours to parts of the city. The real show arrives after dark, when showers and thunderstorms are forecast to ramp up and become more widespread. According to the National Weather Service Wilmington, repeated rounds of rain could drop a quarter to a half inch overnight, with some locations picking up an additional three quarters of an inch on Wednesday.
Timing And Commute
Expect spotty showers through this afternoon, then a better chance of steady, at times heavy, rain once the sun goes down. That wet pattern is likely to linger into the Wednesday morning commute. As noted in our foggy Memorial Day start, the ground is already coming off a damp stretch, so drivers should plan for slower traffic, extra braking distance, and soggy parkways to kick off midweek.
Flooding Risk And Safety
Forecasters point out that soils across much of central Ohio are already fairly wet, which means repeated downpours could quickly lead to localized flooding, poor drainage issues, and brief ponding on streets and in low-lying spots. If you come across standing water, turn around instead of trying to drive through it, and consider moving vulnerable items in basements or ground-level storage to higher shelves.
Bottom Line
Tuesday afternoon stays warm and mostly dry for many, with only a slight chance of a pop-up storm. Conditions turn noticeably wetter overnight as showers and thunderstorms spread across the area and linger into Wednesday, May 27. Keeping an umbrella in reach for evening plans and the Wednesday morning drive will be a smart move, along with checking local updates as the rain pattern unfolds.
