Jared Smith founded @chswx on Twitter in 2008 as an experiment in disseminating weather data through social media. In the ensuing decade-and-a-half, @chswx has provided live coverage of tropical cyclones, tornadoes, severe weather, and even a couple bouts of winter weather to the good people of Charleston, SC.
We are back into cooler weather on Thursday in the wake of a cold front which will sweep through the area overnight. We’ll start the day in the mid-40s with a bit of a westerly breeze that’ll stay persistent throughout the day. Clouds will be few and far between, but the ongoing influx of cold air will keep highs pinned into the upper 50s. Overall, though, a rather nice if not slightly-cooler-than-normal January day lies ahead.
Wednesday could be a busy weather day here in the Lowcountry as a very dynamic storm system moves into the eastern half of the continental US, dragging a cold front through the Southeast throughout the day with showers and thunderstorms ahead of it.
There’s not too much to write home about in the weather department for Tuesday. We’ll get off to a near-freezing start in the metro area, with temperatures dipping below 32° further inland as well as in more rural spots. Plenty of sunshine, though, will help drive temperatures to around 60° in the afternoon. Overall, a bright, brilliant late January day.
The week ahead will feature temperatures generally at or slightly below normal for this point of the year aside from Wednesday, when temperatures will head into the low 70s ahead of a cold front.
Sunday will be an active weather day across the area as a somewhat complex storm system moves through the Southeast US. Needed rain will fall throughout the day, but some of that rain might be heavy at times near a morning high tide that would cause flooding on a sunny day.
Despite thickening cloud cover and a cool wedge of high pressure building in Saturday, it’ll be the day to do anything outside as Sunday looks more active with some heavy rain at times and maybe some coastal flooding in the morning to boot.
Thursday will be quite a warm day ahead of a cold front that will swing through late night/early Friday morning. We’ll start the day some 15+° above normal as lows only bottom out in the mid-50s. Temperatures will head into the mid-70s in the afternoon, with some upper 70s possible in spots.
It’ll be a bit of a windy day: expect winds to kick up to 15-20 MPH sustained with gusts 25-30+ MPH particularly in the afternoon hours. Higher speeds will be possible on bridges, and a Lake Wind Advisory is in effect for Lake Moultrie tomorrow as well. Hold on to your hats and steering wheels if navigating the bridges is in your travel plans tomorrow.
There will be a slight chance of showers as the front gets closer Thursday evening. Some of the high-res guidance sparks some additional showers as a remnant boundary ahead of the front itself perhaps intersects a seabreeze, but widespread heavy rain is not expected and no thunderstorms are forecast.
Temperatures look to stay well on the warm side of normal heading into the weekend, especially Wednesday and Thursday before a front late Thursday brings temperatures back down a little bit.
The rest of the work week will be punctuated with a warming trend through Thursday before a cold front knocks temperatures down slightly for Friday. There will be a few shower chances, but mostly after dark.
We have another round of subfreezing lows ahead for tonight, with clear skies and calm winds allowing temperatures to fall to the low 30s to start the day away from the warmer coastline. It won’t be a terribly long-duration freeze, but regardless, make sure pets are in and plants are covered again tonight.
After that chilly start on Monday, we’ll see temperatures head into the low 60s in the afternoon as shortwave ridging aloft and more southerly winds kick in. We’ll see an increase in high clouds as the day goes on, but overall, expect plenty of sunshine for any outdoor Martin Luther King, Jr. commemorations.
