As much as 1 inch of snow is predicted by late evening for Augusta and surrounding areas northwest of the city, said Jeff Linton, a meteorologist with the National Weather Service in West Columbia, S.C.
"There's near a 100 percent chance of precipitation," Mr. Linton said. "We believe the rain will change into snow or a mixture of rain and snow."
That would mark the second appearance of snow in the Augusta area this week.
The National Weather Service has issued a winter weather advisory until 10 p.m. Though weather officials say precipitation will end by early evening, driving conditions could be affected throughout the night.
"The cooler temperatures will mean that it's possible for the wet roads to become icy," Mr. Linton said.
Temperatures will stay around the upper 30s for most of the day, but will drop to the mid 20s tonight, he said.
Emergency service crews are prepared for the snowy conditions, said Pam Tucker, Columbia County's emergency services director. Crews will be out this evening preparing the roads with salt and sand, she said.
"No forecaster can be certain on how bad it will be, but all of them agree we'll get some snow," Mrs. Tucker said. "The bottom line is everyone needs to drive much slower in this kind of weather."
Mrs. Tucker said motorists should be especially careful on bridges and overpasses, which freeze sooner than roadways.
Mr. Linton said the slick conditions will likely subside by Sunday morning.
