The coldest air of the season so far will move in Wednesday night through Saturday morning. After a very mild December, these single-digit wind chills could feel like a shock!

Light snow showers possible through the morning in southern Ohio, but roads shouldn't be impacted from the snow until the afternoon and evening hours. 

Meanwhile, watch for lake-effect snow showers on and off through the day Thursday in far northeastern Ohio, which could impact visibility and roadways.

Additionally, we are tracking the coldest air of the season, with highs today in Ohio only reaching the 20s with wind chills in the teens into the afternoon. These cold temperatures could create icy and slick spots, even with light precipitation.

Winter weather alerts include Winter Storm Warnings for counties close to the Ohio River and Winter Weather Advisories for most of southern and southeastern Ohio. These areas need to stay winter weather-ready, especially Thursday evening commute.

Late Thursday afternoon, snow becomes for widespread, mainly across southern and southeastern Ohio. Bands of moderate to heavy snow are possible, which could reduce visibility.

Amounts will be highest in southern Ohio with 2-4 inches possible in some areas, especially in southeast Ohio.

Even a light dusting near I-70 of up to a half-inch could cause travel problems because the snow will easily stick to the very cold pavement.

Allow extra time and stopping distance Thursday night.

This is a fast-moving system, so skies will clear out early Friday.

Look at the wind chills for Friday morning; make sure the kids are prepared and protected at the bus stop.

With cold northerly winds, lake-effect snow will set up in northeast Ohio through Friday night.

We are watching for the potential for a bigger snow event in the snowbelt Thursday night into Friday, with 4-7 inches of snow possible there.
