The blast of cold air from the Great Lakes that is bringing snow and rain to parts of South Carolina will likely stick around longer than initially expected.
As much as four inches of snow could fall in parts of Lancaster and Chester counties on Wednesday, said forecasters at the National Weather Service in Columbia. Other parts of the central Midlands, such Richland, Lexington and Sumter counties could see anywhere between a dusting up to an inch of snow.
A winter storm warning has been issued for Newberry, Fairfield and Kershaw counties through 7 p.m., while a winter weather advisory has been issued for the majority of the central Midlands, also through 7 p.m.
Precipitation from the cold front, which in many parts is currently rain, will transition to snow or a rain-snow mix in some areas of the Midlands as noon nears, according to the latest briefing by forecasters.

The snow or rain-snow mix is expected to stick around through the afternoon. It’s expected to fall mainly along and to the north and west of the Interstate 20 corridor.
There is not much confidence on how much snow will accumulate, because temperatures could be above freezing where the snow or snow mix is falling. As of late Wednesday morning, the snow that was falling was melting when it made contact with the ground.
Just before 11:15 a.m., the National Weather Service reported that a rain-snow mix was falling near the Lexington, Peak and Ballentine exits of the interstate.
