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.
Charleston, SC weather radar at 11:01 PM Eastern Time.
We in #chswx continue to carefully watch a line of thunderstorms to our west as it presses toward the coast tonight. Satellite and radar reflectivity increasingly show the line weakening as it approaches the area, which is expected as the parent storm system lifts into the Northeast, taking the best dynamics with it. However, there is some elevated instability in place, and with strong winds a couple thousand feet off the deck, we could still see some showers produce some gusty winds if they hold up to the coast. Rumbles of thunder can’t be ruled out either, especially around I-95. While the severe weather threat is marginal, it is non-zero, so a couple downed trees cannot be totally ruled out.
Temperatures will remain rather warm tonight, only bottoming out in the mid-60s Sunday morning as strong southwesterly winds aloft continue to pump in warm air from the Gulf of Mexico.
Unseasonable warmth will continue through the weekend as the Charleston area remains within the warm sector of a rather potent storm system that is bringing heavy snow to Wisconsin and severe weather to Oklahoma, Texas, and Arkansas. Fortunately, we look to miss out on much, if not all, of the severe weather, but unsettled conditions will continue well into next week. A washout is not expected, but scattered showers will be possible from time to time.
This week will be punctuated by continued warmer-than-normal temperatures with another storm system for the weekend. Monday will continue to feel more like January should, with highs in the low 60s (still a few degrees above normal for January 6) under clear, sunny skies. More clouds move into the area for Tuesday ahead of a dry frontal passage that will knock temperatures back to around 60° for Wednesday. Thereafter, a warming trend takes hold as a storm system rumbles its way toward our neck of the woods. Rain chances start to kick back in Friday — along with a return to the 70s — as we head into the weekend. (Don’t cancel any weekend activities just yet! Forecast will need fine-tuning.)
Water on the ground. We saw a lot of this in Charleston during 2019, from varying sources.
2019 proved to be another busy year for our weather, particularly when it comes to coastal flooding. Beyond the flooding, though, we had plenty of heat and another brush with a hurricane. (Seems pretty standard nowadays, no?) Let’s dig into the numbers…
This was a pretty busy year in weather, for sure. I’ve got some more retrospective work queued up over the next couple days, but today, enjoy my exclusive conversation with Quintin Washington of Quintin’s Close-Ups fame about the weather that was in 2019 and for the decade as a whole.
Happy New Year to all of you in #chswx-land. Thank you for your reports, your enthusiasm, and your support. A special shoutout to my Patreon subscribers, who make investments in hosting and furthering the technology that underpins @chswx possible. I’m looking forward to continuing our partnership in making Charleston a more weather-ready place to live in 2020 and beyond!
We’ve got another very warm day on tap for Monday as a cold front approaches the area with a few showers (and perhaps a rumble of thunder or two) coming along with it. Temperatures will drop closer to normal for New Year’s Eve and New Year’s Day with pleasant skies to greet us for 2020. Then, things turn unsettled and warm again as we head toward Friday and Saturday as another cold front works its way through the area. I wouldn’t be surprised to see Sunday turn out a lot cooler than 65° — a lot depends on when a secondary shot of cool air moves into the area. Rest assured that the first full week back to work and school looks much cooler!
The last few days of 2019 will be marked with unusual warmth as high pressure at the surface and aloft take hold, helping to dry us out nicely from Monday’s deluge. A few showers will be possible this weekend as a trough of low pressure just offshore exerts influence on our weather, followed by a cold front overnight Sunday into Monday that’ll knock temperatures back closer to normal for New Years’ Eve. Enjoy a brief break from cold rain!
Unfortunately, as expected, widespread flooding is ongoing in downtown Charleston this morning as heavy rain combined with high tide to close numerous roads. Heavy rain will continue throughout the day, with another 4-6″+ expected across much of the Tri-County area through tonight.
Holiday travel will become increasingly difficult as a low pressure system develops in the Gulf of Mexico and heads our way Sunday into Monday, bringing heavy rainfall, gusty winds, and the threat for coastal flooding to the area.
8:30 PM:This post has been updated with the latest forecast information.
The last work week before Christmas will start out feeling a little more spring-like, with highs topping out in the low 70s Monday and Tuesday before a cold front swings through and sends temperatures a little below normal for Wednesday and Thursday. We’ll see a little warmup as we head into the weekend.
The best chance of rain so far this week will come on Tuesday, primarily from noon into the overnight, as showers and perhaps a few thunderstorms ahead of the aforementioned cold front come through. We’ll then want to watch the weekend for the potential for another coastal storm to get started. There’s a fair bit of uncertainty there still, so don’t change any plans just yet, but keep an eye on the forecast as rain chances become more clear.
