A stream of moisture will lead to periods of rain ahead of a cold front, mixing with snow north of I-70, as low pressure tracks across the Great Lakes. A light grassy accumulation is possible over higher terrain toward morning. Skies will remain cloudy after light snow and rain showers end in the morning, with readings nearly steady in the mid to upper 30s.
A clipper system will pass to the north Monday, keeping skies mostly cloudy, with some late-day rain showers mixing with snow Monday night in the north before ending. High pressure will bring gradual clearing, though chilly weather Tuesday, as flurries end in the northeastern counties.
A brisk southerly flow behind high pressure sliding off to the east midweek will raise temperatures to around 50 Wednesday, before a true arctic cold front arrives on Christmas Eve, with rain turning to light snow and gusty winds.
Temperatures will fall into the 20s Christmas Eve after nightfall, when we could see enough light snow to provide most of Ohio with a white Christmas. Frigid temperatures and some cold sunshine will prevail Christmas Day.
