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 will continue overnight into early Tuesday morning, but rain should be departing the area around sunrise. As high pressure to the north moves eastward, winds turn more southerly, pushing a front back north as a warm front. This will help temperatures start relatively mild for this point in the year (mid-50s) and finish downright warm (low-to-mid 70s) under partly cloudy skies. From here, we should see a few days of rain-free and unusually warm conditions, with temperatures running 10°+ above normal through Friday, when another front gets through and knocks temperatures back to a more standard September reality for the weekend.
The main weather story of the week ahead will be how non-December-like it will feel, with highs running some 10°+ above normal for much of the work week as we sit between fronts.
Expect generally quiet weather this weekend despite a cold front sinking southward halfway through. Saturday will start much warmer than Friday did, with lows in the mid-50s as opposed to the upper 30s. Watch out for some patches of fog to develop in the morning potentially having brief impacts on visibility. Any fog that develops will scour out shortly after sunrise, yielding partly cloudy skies for the balance of the day. Highs will top out in the mid-70s, generally about 5° warmer than Friday despite some additional cloud cover. There’s an outside shot of a few sprinkles later in the day on Saturday as the front gets closer, but the vast majority of us should remain rain-free with measurable rainfall not expected.
The aforementioned frontal zone passes through the area overnight Saturday and stalls out to our south. We’ll see an uptick in cloud cover (though some sun should still break through) with highs likely struggling a bit to the mid-60s at best. (This evening’s guidance suggests even cooler high temperatures are possible, so stay tuned for revisions.) We should remain generally rain-free, though I wouldn’t be shocked to see sprinkles get introduced into the forecast if some of the colder solutions with a stronger high pressure wedge verify.
All in all, though, it won’t be too bad of a weekend. Warm weather fans will enjoy Saturday, while the sweater-inclined amongst us will likely prefer Sunday. So it goes in December as the seasons continue their tug-of-war.
We’ll see a mix of clouds and sun this weekend with a bit of a temperature rollercoaster as a front looks to sag south of the area on Sunday.
Friday will bring a very chilly start — lows in the mid-30s across much of the metro, with colder temperatures perhaps approaching freezing in some spots. Light northeast winds will make it feel a few degrees cooler, too. (Make sure pets and plants are inside tonight.) Highs in the afternoon will rebound to the mid-60s, about 5° or so warmer than we saw on Thursday. Expect scattered to broken cloud cover.
Saturday will turn warmer ahead of the aforementioned front, as highs will peak in the mid-70s. We’ll see a mix of clouds and sun continue with showers generally dissipating before they arrive.
The front should sag south of the area by Sunday, knocking temperatures back down about 10° in the afternoon with highs only peaking in the mid-60s. Showers are unlikely, though we’ll want to keep an eye out Sunday night given some model disagreement. That being said, the bulk of the weekend should get in generally rain-free, and while we might want to see more in the way of sunshine, it won’t be too bad at all.
A cold front will swing through tonight, ushering in a cooler and drier airmass for Thursday. We’ll start the day in the low 40s, but gusty post-frontal winds will make it feel closer to 35°. Cold advection will keep afternoon high temperatures pinned into the mid-50s at best despite nearly full sunshine. A few clouds will develop late as a coastal trough begins to take shape, but other than that, expect a rather bright Thursday.
Our next rain chance arrives tomorrow as a strong cold front moves through the area. Expect a band of showers and maybe a few rumbles of thunder to roll through the area roughly from sunrise to mid-afternoon. (Exact timing of these lines can be a bit of a challenge, hence the range.) While wind shear will be decent, instability will be sorely lacking, and so there’s very little concern for any severe weather from this system (unlike what folks in Louisiana and Mississippi have seen this evening). We won’t get a whole lot of rain this go-around, either — generally expect a tenth to a quarter-inch of rain, with slightly higher amounts around I-95 and points west. Temperatures will jump into the mid-70s early in the day with warm air pumping into the area ahead of the front.
Said front will lag the rain by a few hours, but it should get through around or after sunset Wednesday, yielding a much cooler day on Thursday. Expect highs in the upper 50s on Thursday despite almost full sunshine. It’ll be a little breezy, too, so you’ll want the hoodie or light jacket.
Temperatures rebound a little on Friday after starting in the low 40s. We’ll see highs top out in the mid-60s with a few more clouds in the area, but still plenty of sunshine and a little lighter winds to enjoy a nice Friday outdoor lunch. From there, the 70s return and hang around for a few days through the weekend into early next week — not exactly the most December-like way to start December, but that’s how things go around these parts.
Quiet weather continues for Tuesday before rain chances return for Wednesday as a cold front comes through. Temperatures on Tuesday start around normal in the mid-40s and will rebound nicely into the low 70s in the afternoon. Winds will be calmer, making that outdoor lunch a little easier, too. Overall, no complaints for Tuesday (weather-wise, anyway).
Aside from some showers on Wednesday as a cold front moves through, this week looks pretty good weather-wise, offering up more in the way of sunshine than we’ve seen in the past couple weeks.
A storm system will approach the area overnight into Sunday, bringing another round of rain chances to the area primarily tomorrow morning into early afternoon.
We get a good break from the gray skies on Saturday as we find ourselves between storm systems. The lull will bring us a nice, seasonable day, with lows in the mid-40s followed by highs in the mid-to-upper 60s, right in the ballpark for where we should be at this point in the year. The only fly in the ointment will be the risk for minor to moderate salt water flooding around the 9:29am high tide.
Clouds build back up Saturday evening as the next storm system makes its approach to give us another round of rain for Sunday. A warm front will lift north across the area throughout the day, allowing temperatures to top out in the mid-70s despite showers and maybe a thunderstorm or two in the area. The best chance for rain will be in the morning through the early afternoon hours. Expect the front to get through by evening, which will shut off the rain and dry out the air. Winds will be a little breezy with sustained winds approaching 20 MPH with higher gusts.
Sunday will mark the end of this king tide cycle, with minor flooding possible with the 10:28am high tide. A few downpours will be possible with the storm system moving by on Sunday, and we’ll want to watch for any to coincide with the mid-morning high tide.
Improving weather returns to start the new work week; the next shower chance will be mid-week, followed by seasonable temperatures to start December.
