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.
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.
2022 will come to an unsettled end across the Lowcountry as showers and perhaps a few thunderstorms develop and move through ahead of a cold front. A stronger storm or two will be possible near I-95, but otherwise expect generally off and on showers. The best risk for showers will occur in the afternoon through the early evening hours; yes, it is conceivable we may have the precipitation out of here as the clock strikes midnight. It will certainly be mild, with highs in the low 70s. Temperatures will run in the upper 50s as 2023 begins, so it should be fairly comfy with a light jacket.
The atmosphere will be drying out during the day Sunday, with cloud cover decreasing and some drier air moving in. It’ll still be warm, though, thanks to high pressure ridging aloft: once again, expect highs in the low to mid-70s. Overall, not a bad start to 2023!
After a high of 62° today — the first time since December 17 that we’ve crossed the 60° threshold — we will be back into the 60s tomorrow across the metro, with temperatures running a few degrees warmer than they did today. Most notably, those of us east of Highway 17-A will remain above freezing into tomorrow morning for the first time since December 23. Those of you along and inland of 17-A will want to take freezing weather precautions for just one more night as lows dip below 32° for a time, with a few upper 20s possible in more sheltered locations. However, many of us will not need to drip faucets or take other precautions tonight (though bringing your pets in is always a good idea this time of year).
