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. It continues to appear that we should stay liquid in Charleston County, especially near the coast, so no Ravalanche redux is expected this go-around. As NWS put it in a briefing call this evening, this is a nuisance event rather than a more impactful event.
Any ice that does form will melt during the day as we should see temperatures creep above freezing across much of the area. A more pronounced warming is likely to take place as a warm front lifts northward across the area later Sunday, though it remains to be seen just how far north the warm front can erode the strong wedge of high pressure that’ll be in place. It’s possible that some of us further inland could be stuck in the 30s while we warm to near 60° near the coast in the afternoon and evening. From there. a band of showers and perhaps even a few thunderstorms will sweep through the area later Sunday evening into early Monday morning. Then, a cold front sweeps through the area by daybreak Monday, and sets the stage for a very cold final week of January.
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. Elsewhere in the Charleston Tri-County area, we’ll deal with periods of cold rain as well as some windy conditions. Comparatively, though, this will be this storm on easy mode for a lot of us — some really treacherous conditions are likely to develop across the northern half of the state into NC. Read on to learn what’s most likely to happen in your neck of the woods.
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. Enjoy this — as mentioned, things will start getting stormy and chilly by Saturday.
Temperatures will warm up for the second half of the week ahead of what is shaping up to be a rather messy weekend, with the risk for winter weather increasing especially away from the coast.
Chilly mornings will continue through Wednesday as another reinforcing shot of cool air moves in overnight Monday into Tuesday. We’ll start Tuesday back in the mid-to-upper 20s, but northwesterly winds around 5 MPH or so could make it feel closer to 20°, so be sure to layer appropriately heading out to work or school. Temperatures will only make it to the low 50s as the influx of cool air continues throughout the day. Expect a scattering of clouds, but still plenty of sunshine.
