Cooler air will continue to overspread the area tonight, and warm air overrunning the shallow layer of cold air could help to generate some freezing rain or drizzle generally inland of 17-A overnight into tomorrow morning. Folks in inland Berkeley and Dorchester counties remain under a Winter Weather Advisory until 1PM Sunday for this threat. The main concerns will be a glaze of ice on elevated surfaces, perhaps including bridges and overpasses.

A reasonably busy weekend of weather awaits in the Lowcountry as we deal with the south side of a massive and likely potent winter storm, the effects of which are starting to develop across Texas into the Midwest before spreading eastward during the day tomorrow into the Mid-South and eventually to the Eastern Seaboard. For our part, a Winter Weather Advisory has been hoisted for inland Berkeley and Dorchester counties, with some freezing rain expected between Saturday night and Sunday morning.

After a high of 72° on Thursday, we'll turn progressively cooler heading into the weekend as a large storm system affects much of the southern and Mid-Atlantic states over the next few days. Fortunately, the risk for accumulating ice continues to decrease into oblivion for much of the Charleston metro area.

Thursday looks like the nicest day we'll have for a little while before the well-advertised winter storm system impacts the South, followed by a round of Arctic air to kick off next week. Temperatures Wednesday start in the low to mid-40s — a marked increase from the low of 26° at the airport this morning — before warming to the upper 60s to perhaps even around 70° under mostly sunny skies.
