Cincinnati is waking up Wednesday to clear skies and temperatures in the mid-50s, but the day will heat up quickly. Patchy morning fog should fade before 9 a.m., making way for mostly sunny skies and a high near 85. The bigger shift comes later this week, when rain knocks down the late-season warmth.

Warmest Days Arrive Before The Front

Wednesday will stay dry with light southerly winds, and Thursday looks even warmer, with mostly sunny skies and a high near 90. The National Weather Service’s Wilmington office says the region should remain dry through most of Thursday before showers begin moving in late Thursday night.

The latest outlook is a meaningful update from Hoodline’s earlier forecast, which pointed to a warmer stretch but had less detail on the sharp cooldown ahead. There are no active weather advisories for the Cincinnati area.

Friday Brings The Week’s Wettest Weather

Rain chances rise after 2 a.m. Friday, followed by a cloudy day with rain showers and a high near 74. The chance of precipitation reaches 90%, with expected rainfall between one-half and three-quarters of an inch.

Showers could linger Friday night before tapering off early Saturday. Anyone with outdoor plans should expect a soggy commute and potentially slick roads, while thunderstorms appear limited because the atmosphere is expected to be only marginally unstable.

Cooler, Drier Weekend Follows

Saturday turns mostly sunny but noticeably cooler, with a high near 67 and a northeast wind around 8 mph. Sunday should reach about 70 degrees, though a slight chance of showers remains before 2 p.m.

By Monday and Tuesday, sunny skies return with highs near 65. Overnight lows will also dip, falling to around 47 Sunday night and 43 Monday night — a clear sign that the calendar is finally catching up with the weather.

The National Weather Service forecast calls for the cooler and drier pattern to continue into early next week.
