Thursday: Record cold in the morning with single-digit wind chills possible

/ at 8:34 PM

With plenty of snowpack still on the ground, expect a very, very cold night that should set daily records on Thursday morning as lows could fall to as low as 15°. Mix in the persistent northerly wind and wind chills may fall into the single digits. If you’re headed outside tomorrow morning, be bundling up in lots of layers and be very careful for re-frozen ice on steps, sidewalks, and roads.

Additional cloud cover on Thursday isn’t gonna do us a lot of good in the melting department; highs should once again only peak in the upper 30s with mostly cloudy skies generally expected. Wind will remain a bit of a factor, and it’ll feel like the 20s for much of the daytime period.

Getting into Thursday night, I’d expect another round of refreezing and black ice concerns. If you don’t have to travel, it’s probably best to stay hunkered in one more day.

Rest of today: Clearing, still cold, a little melting that’ll refreeze tonight

/ at 8:05 AM

Precipitation has ended across the Lowcountry after an eventful night of winter weather. Snow totals are coming in and a more complete analysis will be doable later today. For now, though, it’s quite cold, and will stay that way for much of the day with so much sleet/snow cover. Cloud cover will clear out, which may be the only thing that gets us back above freezing this afternoon for a brief period. Anything that melts will likely re-freeze, though, promoting a black ice risk across the area especially on bridges and overpasses. (We have a few days of this ahead, too.) If you don’t have to travel, don’t — quite a few roads, including the Ravenel Bridge, Ashley River bridges, and the Northbridge are closed to traffic. Monitor local media for updates on roads throughout the day — and try to have a little fun, too!
