Now that Bluesky’s added per-account notifications, you can now get your weather information pushed to you on demand whenever I post. One less reason to hang around over *there!*
Yes, that is indeed thunder, with some elevated instability contributing to some convection despite the fact that we are in the 30s and 40s.

The freezing line is bisecting the Tri-County area roughly in the 17-A corridor. Should stay quite chilly for the next few hours before a warm front lifts north.

Along and west of the 17-A corridor, temperatures remain at or below freezing. It’s here where the potential for freezing fog is greatest in the near term, including places like Summerville, Moncks Corner, and around Lake Moultrie.

Temperatures are beginning to warm above freezing east of the 17-A corridor. No indication of significant issues on roads right now, thankfully. Foggy conditions continue, though, so be cautious for sudden drops in visibility.

Will be interested in precipitation reports if you’ve got them. We are at a bit of a disadvantage with the Charleston radar being out; Columbia can’t see as close to the ground here, and the beam is probably overshooting any shallower rains.

Temperatures have run colder this morning than anticipated, prompting an expansion of the Winter Weather Advisory to the coast. Light ice accumulations are possible on elevated surfaces.

A glaze of ice remains possible overnight for portions of inland Berkeley and Dorchester counties. The most substantial rain of this event arrives Sunday night, followed by a cold front that will bring on a very cold final week of January.
Tonight & Sunday: Light glaze of ice expected inland giving way to showers and storms in the evening
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.

Temperatures continue to fall across the area, and will be reaching the 30s fairly soon from northeast to southwest. As high pressure builds in, winds will increase, with gusts near the coast between 30-35 MPH possible.

Cool and cloudy Saturday ongoing. As we get later in the day, the much cooler air to our northeast will make a push further into the Lowcountry, increasing the risk of drizzle overnight, which could become freezing drizzle further inland.

Expect a windy but mostly rain-free Saturday before the well-advertised winter storm system arrives from the west by evening. Freezing rain remains possible well inland; for the rest of us, periods of cold rain ahead of a band of showers and storms Sunday night.
Weekend forecast: Storm system arrives with freezing rain inland, cold rain at the coast
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.
