Snow could start after sunset on Saturday
According to a forecast from the South Carolina DNR, moisture infiltrates over South Carolina as plain, cold rain late on Friday. We should prepare for a day-long soggy rainfest Saturday. After sunset Saturday, rain changes to snow starting along the North Carolina-South Carolina border in Oconee, Pickens, and Greenville counties. Snow, heavy at times, migrates south and east along the I-85 corridor during the day Sunday. A layer of warm air aloft sneaks in Sunday afternoon, causing a 4 to 6-hour transition to a snow—sleet freezing rain mix. Freezing rain amounts to 0.4 to 0.8 inches likely along the I-85 corridor. That’s on top of the 4-8 inches of snow. Higher snow amounts—10 to 12 inches—are in the models for the higher elevations along the South Carolina-North Carolina border. After sunset on Sunday, the snow tapers off.
