The National Weather Service says several inches of snow could fall, but the forecast of accumulating ice could prove to be a bigger problem.
As is typical in these situations, Weather Service and private meteorologists caution that numerous changes in the forecast are possible before the precipitation starts around daybreak Monday. But they are convinced that some type of winter storm will cross the region.
Lasting freezing temperatures combined with rain, sleet and snow could make driving dangerous.
S.C. emergency officials are preparing for the storm."This could be a very different scenario than the recent Christmas snow when temperatures prevented roads from icing in most locations. It will be colder going into this weather event and could produce treacherous driving conditions throughout most of the state," S.C. Highway Patrol Col. Kenny Lancaster Jr. said.

Snow could fall in York County after 3 a.m. Monday and continue through the day. By Monday afternoon, the snow might mix with sleet but should taper off toward evening, said Rodney Hinson, a meteorologist with the National Weather Service. Forecasters aren't sure how much snow will accumulate, but the county could see a few inches.
"There's still a question about temperatures. They could rise above freezing, or they could stay below freezing all day (Monday)," Hinson said.
Temperatures are expected to range from the low 20s to mid 30s throughout the storm.
Highway Patrol officials urge motorists to be wary of snow and black ice, which looks like water. They encourage drivers to slow down and keep a safe distance between vehicles, and note that bridges or overpasses might ice before roads do. The Highway Patrol requests that motorists dial *HP only for true emergencies such as collisions or being stranded in a vehicle. Call the S.C. Department of Transportation at 511 for traffic conditions, and pay attention to advisories from local media and state agencies' websites.
