Cincinnati starts Sunday with fog and mist, but the gray should be short-lived. Temperatures near 62 degrees at Lunken Airport will give way to sunny skies and an afternoon high around 78.

Fog Lifts As Sun Takes Over

Patchy river-valley fog is expected to lift through midmorning, according to the National Weather Service. Northwest winds will run from 2 to 9 mph, and a few isolated showers or thunderstorms could pop up this afternoon, with the better chance north of the I-70 corridor.

Cool Night Leads Into A Mild Monday

Sunday night should be mostly clear, with temperatures falling to around 57 degrees and light northwest winds. Monday brings another sunny day with a high near 77, followed by a sunny Tuesday topping out around 80.

Midweek Heat Returns

Temperatures climb into the mid-80s by Wednesday and Thursday, reaching about 84 and 86 degrees, respectively. Thursday carries a slight chance of showers and thunderstorms after 2 p.m., while Friday and Saturday look sunny with highs near 84 and cool overnight lows in the low to mid-60s.

No watches or warnings are in effect for the Cincinnati-area forecast at this time. For outdoor plans, Sunday afternoon and Monday offer the clearest combination of sunshine, comfortable temperatures and low rain chances.
