The combination of falling temperatures and a low pressure system from the south could result in as much as seven inches of snow for the region by Thursday morning, say weather experts.
Wednesday’s commute, coming and going, should not be affected too much by the weather. There is the chance of some ice in the morning as temperatures are expected to be just above freezing. An ice advisory from the National Weather Service is in effect until noon Wednesday.
This afternoon, rain is expected to start about 4 p.m., before turning to snow about 8 p.m. A winter storm warning will be in effect until 7 a.m. Thursday.
“The storm is on the track that we usually see our biggest snowfalls,” said Jeffrey Taylor, a meteorologist with the National Weather Service at the Greenville-Spartanburg Airport, on Tuesday.

Factors affecting the amount of snow are the speed of the storm and the path the low pressure system follows, Taylor said.
If the low pressure system shifts farther to the east, or moves faster than anticipated, snow accumulations would be less, Taylor said.
Conversely, if the low pressure system shifts close to York County, or the storm moves slowly northward, snow accumulations would increase, he said.
The snow is expected to be heaviest when the low pressure system passes close to the region, according to the National Weather Service.
The snow is expected to affect Thursday morning’s commute. The impact of the storm on traffic will be affected by how many businesses and schools close or delay opening, forecasters say.
Even after the snow stops the weather isn’t expected to get better until next week, Taylor said.
Temperatures will be below normal until Monday with morning temperatures around 37 degrees.
Lawmakers in Columbia, anticipating the bad weather, voted to take Thursday off. The forecast for Columbia, the Midlands and areas to the east is for rain from the second storm.
Tonight’s storm follows Tuesday morning’s snow showers that resulted in about an inch of snow in the region.
