Snow, ice still likely Thursday, forecasters say; winter storm watch in effect

The weather system threatening to bring a layer of snow and ice to South Carolina shows no signs of abating, forecasters are saying.

A winter storm watch now is in effect for York County, the Upstate and all of the Charlotte metro area.

Temperatures will reach into the 40s this afternoon, but plummet into the mid 20s as clouds move in tonight.

A mix of freezing rain, sleet and snow is expected to start falling around sunrise, possibly bringing up to an inch of snow, said meteorologist Terry Benthall of the National Weather Service.

As temperatures rise into the mid 30s, the precipitation will change to freezing rain around lunchtime, before becoming all rain in the afternoon. A half-inch of ice is possible before that happens, Benthall said.

The storm could be particularly hazardous because the initial layer of snow may be topped by a layer of ice. That would make roads especially slippery for drivers. Timing is also a consideration: The frozen stuff should be falling around the time of the morning commute.
