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.
Showers and maybe a thunderstorm will be accompanying a cold front tonight into tomorrow morning. There could be some brief pockets of heavy rain and gusty winds, but no severe weather is expected.
The front will get through around daybreak or so Friday morning. Persistent cloud cover and cold air moving in will limit highs to the low 60s. Showers become possible once again later into the evening hours as low pressure develops to our northeast; any rain, if it does end up falling, should be relatively light.
As low pressure departs, skies will clear and temperatures will tumble. Expect to wake up to mid-30s on Saturday morning, with highs struggling to 50° in the afternoon despite full sunshine. Subfreezing temperatures are expected Sunday morning, with a few spots well inland perhaps dipping into the upper 20s. Full sunshine and some shortwave ridging aloft will help temperatures start to rebound a little in the afternoon, with highs in the mid-50s expected. We’ll return to the low 60s for Monday, and will be back in the 70s by Wednesday, so this cold spell won’t have much staying power — good news for warm weather fans, and not so much fun for the cool-inclined amongst us. But so it goes in the “cool season” during a La Niña year here in the Lowcountry.
The rest of the work week will feature a quick warmup (with a brief return to the 70s on Thursday) before a cold front brings temperatures back down to earth for Friday and the weekend.
Tuesday will start a little cooler as light winds and a decent period of clear skies should allow lows to drop into the upper 30s. High pressure will continue to exert itself across the area during the day, with highs heading into the low 60s under mostly sunny skies. Otherwise, there’s not much to write home about weather-wise: We stay with fair weather through Wednesday, and our next rain chance arrives late Thursday before a cold front cools us off for what will otherwise be a quiet weekend of weather.
We’ve got a pretty quiet week of weather ahead aside from a frontal passage overnight Thursday into early Friday morning, which should spread some showers and maybe a thunderstorm through the area. Highs for much of the work week will run in the mid-60s, with temperatures approaching 70° on Thursday. Lows on Monday will bottom out around 50°, with a couple chillier mornings ahead for Tuesday and Wednesday with lows in the low 40s before warming back to 50° for Thursday and Friday morning.
The best chance of rain arrives late Thursday night into Friday morning, with showers expected. A thunderstorm or two can’t be ruled out ahead of the front, either, but timing will generally be a little less favorable climatology-wise for thunderstorms. Rain comes to an end Friday morning, and the cold front will be clearing the area during the day. Cooler and drier air filtering into the area will limit highs to the low 60s in the afternoon. Saturday will be as chilly of a start as we’ve seen since the turn of the year with lows in the mid-30s. Highs on Saturday will struggle to the low-to-mid-50s, while Sunday will run a little warmer with highs in the mid-50s after starting solidly in the mid-30s. Overall, though, not too shabby for the first full work week of 2023.
The first weekend of 2023 is here, and the weather overall looks pretty good across the area, particularly Saturday. Morning cloud cover and lows in the upper 30s will give way to more sunshine and highs in the low-to-mid-60s, still above normal for this point in the year. Sunday will feature more in the way of cloud cover throughout the day as some energy aloft approaches from the west. Despite the cloud cover, expect highs to still reach into the mid-60s in the afternoon. The aforementioned energy could lead toward some isolated to scattered showers breaking out after sunset Sunday into early Monday. Significant rainfall is not expected, though. All in all, not a bad weekend to get out and about!
Friday and the weekend will feature quiet and comfortable weather for early January as cooler and drier air behind a cold front continues to filter in. Temperatures will still be running a click or two above normal, with highs in the low-to-mid-60s each day and lows generally in the low-to-mid-40s. Sunday looks to be the warmest of the three days as another cold front draws closer to the area, which could bring some rain chances late into Monday. Overall, our mild start to 2023 largely continues, and that ain’t bad.
Expect quieter weather for Thursday — and into Friday and the weekend — as a cold front gets through early in the morning. We’ll start the day well above normal with lows bottoming out in the upper 50s. Clouds will scour out post-frontal passage and some cooler air will begin to filter into the area. Temperatures, however, should still be able to reach around 70° in the afternoon for one final time in this warm spell. We’ll turn much cooler as we head into Friday, when highs should only top out in the upper 50s — in other words, Thursday’s lows are Friday’s highs!
Wednesday will be another mild day, with temperatures running in the mid-70s ahead of a storm system which will turn the afternoon and evening hours unsettled with the risk of a strong storm or two.
Tuesday looks to start much in the same fashion as the past few days: at a minimum, patches of fog, potentially dense with visibility below ¼ of a mile at times, should develop overnight and should persist into mid-morning. As of this writing, a Dense Fog Advisory is in effect for Charleston County and Berkeley County around Cainhoy and Daniel Island through 10am. If fog does indeed persist and even expand, you’ll want to be sure to allow extra following distance and use low beams so that other drivers can more readily see you.
Once the fog mixes out, partly cloudy to mostly sunny skies will kick back in, and temperatures should respond by heading into the mid-70s by afternoon (sticking closer to the low-to-mid-60s near the coast, though, given much cooler shelf waters). Clouds should be on the increase in the evening as our next storm system approaches from the west.
We’ve got a few more warm and muggy days ahead to start 2023 before a front gets through mid-week, bringing temperatures closer to early January normals.
