Things are a little crazy in the Carolinas today. We have an Arctic cold front interacting with a weak low rocketing northeast. What kind of nasty weather is Charleston seeing?
AT 1156AM, ET, Charleston was reporting a temperature of 39 degrees with overcast skies. There was widely scattered drizzle in South Carolina, but for now, the heaviest activity was found across the state line in Georgia, and towards Augusta. While temperatures are fairly cool, and heavy precipitation is on its way along the Arctic boundary, temperature profiles aloft seem to suggest that precipitation will remain rain along the coast through the day today. This is very dangerous, because surface forecasts suggest temperatures below freezing for most of the afternoon and into tomorrow morning. Don’t be surprised to see significant freezing rain and sleet throughout South Carolina and the Charleston area tonight. It is for this reason that there is a winter storm warning for coastal South Carolina
Overnight, colder air will move in a loft, and the updrafts that will be responsible for the precipitation will help dynamically cool the local atmosphere, which will usher in a change to snow, after which a few inches of accumulation are possible on top of any accreted ice and sleet. In the wake of the precipitation, expect a chilly day tomorrow, but even as the trough stalls offshore, a warm up is expected through the day on Thursday.
Tomorrow – 1-3″ of accumulating snow on top of sleet and freezing rain falling overnight. Clearing by afternoon High 32, Low 24.
Thursday – Warming a bit, mostly cloudy, High 41, Low 17
TWC: Tomorrow – AM Snow High 32, Low 26
Thursday – Partly Cloudy High 43, Low 22
AW: Tomorrow – A little accumulation of snow and sleet early in the morning; cloudy and cold High 36, Low 26
Thursday – Sun and some clouds High 41, Low 21
NWS: Tomorrow – Snow and sleet before 2pm, then a slight chance of snow between 2pm and 4pm, then a slight chance of rain after 4pm. High 34, Low 26
Thursday – Mostly sunny, (rain through 2AM) High 42, Low 27
WB Tomorrow – Cloudy. Snow or sleet or freezing rain in the morning… Then a chance of snow with a slight chance of rain in the afternoon. High 34, Low 26
Thursday – Mostly sunny. High 42, Low 26
What a freaking nightmare. Much of South Carolina is going to be crippled by this storm, and Charleston is no different. Keep in touch with the Victoria-Weather Forum for updates on Charleston, and the Storm Forum for updats on the southeast in general. Radar is currently not as active as it will be. Also, since this forecast started, temperatures have already dropped 2 degrees in Charleston. Nightmare.
