Cincinnati is waking up to a gray, cool start, with Lunken Field (KLUK) checking in around 52°F and muggy skies early on May 21, 2026. A slight chance of light showers will linger through mid-morning before giving way to mostly cloudy skies and a high near 70°F. A northeast breeze around 8 mph should help keep temperatures in check, with lows tonight slipping to around 55°F.
Late Friday Into Saturday
Rain chances ramp up on Friday, May 22, 2026, as a stronger system moves in and spreads showers and scattered thunderstorms across the region. Some of those storms could be locally heavy, especially south and east of I-71. Forecasters note that some spots could see 1 to 2 inches of rain on Friday, with another half to three-quarters of an inch possible Friday night, raising the risk of localized flash flooding in low-lying areas, according to the National Weather Service.
Timing And Impacts
The first batch of rain is most likely Friday morning into the early afternoon. A stronger band of storms and heavier rainfall is expected to organize late Friday into Friday night, which could make the evening commute a slog with sudden downpours, reduced visibility, and standing water on the roads. Officials stress a familiar rule: avoid driving through flooded streets.
Showers and thunderstorms are expected to hang around into Saturday, though the worst of the forcing should shift eastward by the afternoon, taking the heaviest action with it.
Memorial Day Weekend
Memorial Day on Monday, May 25, 2026, is shaping up to be warm and unsettled, with highs near 81°F. Rain showers are likely before midday, and thunderstorms remain possible into the afternoon. The start of next week looks muggy, with repeated chances for showers and storms and highs in the low-to-mid 80s.
What To Keep In Mind
If you are planning outdoor Memorial Day gatherings, have a backup shelter ready and keep an eye on updated forecasts before you fire up the grill. Heavy downpours can quickly lead to ponding on streets and slower travel. If you encounter a flooded roadway, turn around and do not attempt to drive through it.
