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.
High pressure will be in control for one more day on Thursday. We’ll start the day a little cooler than we did on Wednesday, and certainly much less windy, too. However, a light breeze will still make lows in the mid-30s feel closer to freezing. Temperatures will head to the upper 50s in the afternoon under a mix of sun and cloud cover.
After a day of weather that went more or less as advertised, we get a couple days to dry out before another round of showers and thunderstorms — and maybe some more severe weather — arrives on Friday.
We will stay breezy Wednesday, particularly in the morning, as cooler and drier air blows into the area behind a cold front. We start the day in the low 40s and warm to the mid-50s in the afternoon. A few clouds will be around, but overall it’ll be much sunnier than Tuesday. (Not hard to do!)
Thursday will feature calmer winds and a chillier start. We’ll begin the day in the mid-30s before warming to the low 60s in the afternoon under partly cloudy skies. It should be a fairly quiet, nice day of weather overall.
The quiet doesn’t last, though, as another storm system affects the area on Friday. While it won’t be as windy of a system as Tuesday’s was, it will still bring with it a fairly well-sheared environment which, if paired with enough instability, could yield another round of severe weather. The Storm Prediction Center has the area outlined in a 15% severe weather risk in the Day 4 outlook; we’ll see how this evolves as the rest of the week wears on. For now, though, don’t let the weather radio stray too far…we might need it again later this week.
An unusually potent storm system will affect the area on Tuesday, bringing strong, gusty non-thunderstorm winds, some tidal flooding in the morning, and a squall line in the afternoon and early evening that could bring a swath of damaging winds and maybe a few tornadoes on its leading edge.
The active weather pattern we’ve found ourselves in for the start of the year continues this week as we’ll see at least two storm systems visit the area, with quiet and generally cool weather days interspersed between them.
Monday will feature increasing clouds and a steady east to northeast breeze as high pressure wedges southward. We start the day in the mid-30s and warm to around 60° in the afternoon with clouds steadily increasing ahead of Tuesday’s storm system. Late Monday, a warm front will lift north of the area, which may bring some scattered showers along with it, but we should get much of the daylight hours, if not all of them, in rain-free.
After a rather warm Saturday — the warmest day of the young year so far with a high of 75° — temperatures return to normal on Sunday as cooler and drier air blows in behind a cold front. We start the day in the mid-40s, but the ongoing cool air advection will hold highs to around 60° in the afternoon despite partly cloudy to mostly sunny skies. It’ll be another breezy day; expect winds generally 10-15 MPH out of the west with gusts approaching 25-30 MPH once again.
We’ll likely be waking up to rain Saturday morning as a storm system moves through the area. Rain could be heavy at times, with a half-inch to an inch of rain possible in many spots. It’ll be windy, too: gusts to 30-35 MPH will be possible, so batten down the hatches if you have rain-or-shine outdoor events. The bulk of the rain should exit by early afternoon, though guidance does suggest some wrap-around moisture may keep a few showers around through early evening. From there, we should dry out. Temperatures during the day will be as warm as they’ve been so far in the small sample size of 2024: expect lows in the mid-40s to yield to highs near 70° in the afternoon as warm air advects into the area.
Sunday will be a quieter weather day, with cooler and somewhat drier air working into the area in the wake of Saturday’s storm system. Expect to start the day in the mid-40s with breezy westerly winds keeping highs capped to around 60° in the afternoon under a mix of sun and clouds.
The recent spate of quick-hitting storms continues over the weekend. Friday will get off to a chilly start, with lows around freezing in the metro and likely lower further inland. Highs head to the mid-50s under mostly sunny to partly cloudy skies. Clouds will be increasing late as a Gulf storm system approaches the area, but we get the vast majority of Friday in rain-free.
Showers look to begin around midnight and will last through Saturday morning. Many spots should see an inch or more of rain, with a few spots pushing 1.5-2″. There will be the risk for a few rumbles of thunder, but no severe weather is expected. Rain should depart by mid-afternoon, so it’s not an all-day washout. Saturday will also be notable for how warm it will be: we start the day in the mid-40s and warm to near 70° in the afternoon as we remain in the warm sector of the storm system, about as warm as we’ve been in 2024’s short time.
The storm system’s cold front swings through late Saturday/early Sunday and yields a quiet end to the weekend. Lows in the mid-to-upper 40s will yield to highs around 60° in the afternoon under partly cloudy skies. Quiet weather continues Monday, though a potent storm system looks to affect the area on Tuesday with strong, gusty winds, heavy rain, and maybe some severe weather — stay tuned.
A brief round of rain on Wednesday night will depart the area by daybreak Thursday, leaving behind a little bit cooler air as well as unfettered sunshine. We start the day in the upper 30s to around 40° before warming to the mid-50s in the afternoon — a few degrees below early January normals (60°). It’ll be a little breezy, with winds out of the north and northwest around 10-15 MPH, which will be a contributor to keeping high temperatures below normal despite all the sunshine.
Wednesday gets off to a freezing start across the metro area as lows dip into the low 30s away from the warmer coastline thanks to calm winds and mostly clear skies setting up for a good night of radiational cooling. The sub-freezing air doesn’t last long, though, as moisture increases ahead of a storm system that will be traversing the Gulf of Mexico during the day Wednesday. It’ll fling some showers our direction, primarily from late afternoon Wednesday into the overnight and very early Thursday morning.
The storm system clears the area by daybreak Thursday, setting up a couple quiet days of weather. Expect highs in the mid-50s on Thursday and Friday, with an upper 30s start on Thursday before heading back to near the freezing mark on Friday morning.
The holidays are over, and we’re back at it in 2024. The good news is that mostly quiet weather, except for a wet Wednesday evening, looks to be the rule for the first work week of 2024. A cold front coming by Monday evening (which was able to squeeze out a few showers as it passed) will set us up for a chilly start to Tuesday, with lows around freezing in the metro and likely below further inland. Despite clear skies, highs will only get to the mid-50s — a few degrees below early January normals (60°).
After a freeze in the morning, we’ll get much of Wednesday in rain-free before showers arrive generally around and after sunset ahead of another storm system. The rain from this will be reasonably short-lived, though, and should depart before daybreak on Thursday. We start Thursday around 40° and warm back into the mid-50s in the afternoon under partly cloudy to mostly sunny skies. Aside from a chillier start on Friday, in which we’ll once again flirt with freezing, expect highs to warm to the mid-50s once again under mostly sunny skies. The next storm system looks to arrive Saturday; it’ll probably be a bit more of an effective rainmaker than Wednesday evening’s storm, though it should depart by Sunday morning.
