Wilmington, OH — The National Weather Service in Wilmington has released a detailed hour-by-hour breakdown showing exactly when rain, snow, and wintry mix will occur today through early Sunday across southwest and central Ohio. The chart includes timing for cities such as Dayton, Cincinnati, Columbus, Springfield, Wilmington, and Chillicothe.
Forecasters say the event will unfold differently across the region depending on temperature profiles and how quickly warm air moves in. Locations that begin with a mix of rain and snow this afternoon will likely transition to all rain later this evening, which will limit how much snow can accumulate. Any snow that falls before the changeover is expected to be light and may only stick to grassy or elevated surfaces.
Places that stay snow a bit longer—mainly farther north—could see brief minor accumulation before warmer air arrives overnight. However, the NWS notes that the transition to rain will compress or melt new snowfall quickly, preventing widespread issues.
The timing graphic shows most areas experiencing their highest snow probabilities between 4 PM and 10 PM Saturday, with a transition toward a mix or all rain between midnight and 6 AM Sunday. By sunrise Sunday, most of the region will be experiencing mainly rain, with lingering wintry mix possible in a few northern zones.
Travel impacts are expected to remain limited, though drivers should watch for slick spots in communities that briefly stay colder into the evening. Conditions improve through Sunday as precipitation becomes lighter and temperatures rise.
Residents are encouraged to check updated local forecasts through the evening, as small temperature shifts could affect whether precipitation falls as rain, snow, or a mix.
