A weather system moving through Tennessee Thursday evening will bring a coating of snow (1 inch) tonight to central Ohio, and a rain-snow mix in the far southern part of the state.
Temperatures will reach the mid- to upper 30s this afternoon under partly sunny skies, with increasing clouds, warming pavement surfaces enough to cause most of the snow to melt on contact. Accumulations will cause slippery spots to develop early tonight.
The snow will end quickly from west to east around midnight in the Columbus area.
Later in the weekend, a more potent southern storm will create a swath of snow that will extend across the Ohio Valley to the Mid-Atlantic states by late Sunday, with moderate accumulations and travel disruptions.
Early indications suggest a snowfall of 2 to 4 inches near and south of I-70 and lighter amounts north, but the exact track could shift as we get closer to the event, beginning midday on Sunday.
Behind this storm early next week, much colder air will arrive accompanied by gusty winds and January-like conditions that will linger through the first week of March.
