Tuesday in Cincinnati is pulling a quick costume change. Early this morning, April 21, 2026, clear skies helped temperatures drop into the low 40s at Lunken Field, but a surge of warmer air is set to push afternoon highs into the mid to upper 70s. Southwest winds will crank up as the day goes on, so it will feel breezier than it looks, and scattered showers with a chance of thunderstorms are expected after midnight into Wednesday morning. Think warm, windy daytime weather followed by a soggy, unsettled night.
Afternoon Winds Pick Up
Highs are expected to top out near 77°F with a south wind running from about 3 to 20 mph, and mixing in the atmosphere could drive gusts into the 20s and low 30s this afternoon. According to the National Weather Service, lower humidity combined with that mixing will favor some punchy gusts during the warmest part of the day.
Tonight: Scattered Storms Possible
A weak frontal boundary slipping into the area will bring about a 40% chance of showers and a few thunderstorms after midnight. Most spots should see on the order of a tenth to a quarter of an inch of rain, with temperatures only falling to around 58°F. The National Weather Service Wilmington office notes that any storms that do form could kick up brief gusty winds and locally heavier downpours, so late-night and early-morning drivers should be ready for slick roads and reduced visibility.
End Of Week Outlook
Thursday is the pick of the workweek for warmth and sunshine, with highs near 82°F and generally quieter weather. A stronger system is lined up for Friday into Saturday, bringing higher chances for rain and thunderstorms and the best shot at a more prolonged period of steady rain overnight Friday into Saturday. By Sunday, conditions look drier and milder again, with mostly sunny skies and highs back in the mid 70s, making Thursday and Sunday the better bets for outdoor plans.
What To Do
Frost and freeze advisories were posted for parts of the broader region through 10 a.m. Tuesday, so gardeners should shield any tender plants from the early chill. Later in the day, secure lightweight patio furniture and anything else that might blow around before those afternoon gusts really get going. With showers and storms on the table after midnight, keep a compact umbrella handy and check the National Weather Service or your usual weather app for updates before heading out.
