Wave goodbye to humidity for a few days

/ September 23, 2021 at 8:43 AM

Beautiful day ahead in the wake of a cold front which swept through last night. Cooler, drier air will filter in throughout the day, and highs should only top out around 80° as a result with low humidity and copious amounts of sunshine. Pretty fantastic.

This will begin a bit of a weather winning streak for us, with tranquil and comfortable conditions continuing well into next week. Enjoy!

Scattered showers and storms possible as a cold front moves in today

/ September 22, 2021 at 8:43 AM

We have one more warm and muggy day ahead with a scattering of showers and thunderstorms ahead of a cold front; once this front gets through tonight and into tomorrow morning, conditions will take a turn for the awesome to close out the work week and head into the weekend. For today, though, keep rain gear handy. It won’t rain all day but if it does, it could be briefly heavy. (At least we’re getting some sun this morning!)

Astronomical fall begins this afternoon at 3:21 PM — it will certainly feel a lot like this after today. Looking forward to it!

Rain — and the flood threat — continues into Tuesday

/ September 20, 2021 at 8:18 PM

Periods of heavy rain will remain possible overnight into Tuesday as we remain within a little firehose of moisture funneling between high pressure to the north and low pressure to the south. At 5PM, the airport had recorded 1.47” of rain and downtown had received .80” with more to come. (It wasn’t as bad as Savannah, though, which has recorded almost 6” of rain just today, shattering a 136-year-old record.)

A Flash Flood Watch continues until noon Tuesday, though if wetter trends continue this could be extended further into the day. Of most concern is the 8:50 AM high tide, which may top out between 7.2-7.4’, already well within minor flood stage. Salt water on a few roads is a given; we’ll need to see what kind of rain is in the area Tuesday morning to determine whether additional water piles up on top. Either way, expect another soggy day with another 1-2” of rain in the forecast, with locally heavier amounts. Temperatures will once again be held down into the low 80s at best given copious amounts of cloud cover and rainfall in the area.

Salt water flooding will continue to be an issue over the next few days, with another bout expected around the 9:18 PM high tide Tuesday night and then again with Wednesday morning’s high tide around 9:31 AM. Keep attuned to coastal flood advisories from the National Weather Service.

Scattered showers and mostly cloudy skies the rule today

/ September 16, 2021 at 8:28 AM

Stay ready for scattered showers and maybe a couple thunderstorms today as the remnants of Nicholas, well to the west, sling some moisture our direction. Cloud cover will keep temperatures down in the mid-80s, but mix in the humidity and it’ll still feel like the low 90s. Watch for a brief downpour or two at times, but widespread heavy rain is not looking likely this far to the east.

Watch for a storm or two today, but otherwise, a warm and humid mid-September day

/ September 15, 2021 at 8:10 AM

Today will have a really summer-like feel to it. We’ll see isolated to scattered showers and thunderstorms across the area pretty much all day, with the best risk closer to the coast (and Charleston proper) beginning late morning into early afternoon, then steadily moving inland with time. Not everyone sees rain today, but a brief downpour can’t be ruled out pretty much anywhere.

Temperatures will top out in the mid-80s. Factor in dewpoints in the low 70s and that will yield heat indices in the low 90s. Not terribly oppressive by Charleston standards (or even abnormal, really), but yes, it gets to wear on you by mid-September.

First storms in a few days possible on Tuesday

/ September 13, 2021 at 9:22 PM

Dewpoints are headed up, and that will bring along a slight chance of thunderstorms for Tuesday afternoon, primarily along and ahead of the seabreeze boundary as it moves inland. We’ll start the day in the low 70s across much of the area before temperatures head into the mid-80s in the afternoon. It won’t be sweltering, but it won’t exactly be fall-like, either.

It’s worth noting that we could see some patchy fog in spots tomorrow morning. Be ready for sudden changes in visibility during the commute, and don’t forget the low beams if you do encounter fog.

Heavy rain, enhanced by Tropical Storm Mindy, possible around the morning high tide

/ September 8, 2021 at 10:10 PM

We have a soggy Thursday coming up as Tropical Storm Mindy, which was named and made landfall on the Florida Panhandle in the space of four hours earlier this evening, moves to our south, bringing along a tropical airmass that will help squeeze out quite a bit of rain particularly in the morning. High tide at 10:19 AM will be of particular interest as high-resolution models strongly suggest that heavy rain will be in the area ahead of and around that time. This could spell a flooding concern for downtown Charleston depending on where the heaviest rain sets up. Be cautious during tomorrow morning’s commute, and be ready to use alternate routes.

The heaviest rain will fall in the morning, but there will be the risk of showers and thunderstorms through the evening as a cold front will move through the area. Once that front’s through, though, we’ll be set up for a nice weekend. Meanwhile, Mindy will be shooed away from the area along the aforementioned cold front, and there are no additional tropical concerns of note for now.

Temperatures will top out just in the low 80s thanks to the prevalent cloud cover and rainfall, well below early September norms. As we head into Friday and the weekend, temperatures will continue to run a little below normal — another taste of fall as we head deeper into September.

More scattered storms and mugginess for Wednesday; watching a Gulf disturbance, too

/ September 7, 2021 at 9:02 PM

Scattered showers and thunderstorms will once again figure into the forecast for Wednesday. An approaching cold front as well as some upper-level help in the form of a trough will contribute to scattered to numerous storms in the afternoon and evening hours. Brief bouts of heavy rain will be possible, and a few storms could get gusty, but severe weather appears unlikely.

We’ll get off to another muggy start with mid-70s lows. Expect mid to upper 80s until storms get going in the afternoon. Mix in the humidity and it will feel closer to the upper 90s.

Finally, we will want to keep an eye on water levels around the 10:12 PM high tide for the potential for some minor salt water flooding as water levels could get near 7’. We might have some rain in the area around that time, too. Thus, time of high tide will merit close watch.

Dewpoints steadily falling today as weather turns quieter

/ September 2, 2021 at 8:55 AM

A cold front pushing south across the area is ushering in some lower dewpoints this morning, especially further north and west, making outdoors a little bit more comfortable today than we’ve seen in the recent past. We’ll stay warm with temperatures in the mid-to-upper 80s, but the gradual decrease in humidity throughout the day will make it more bearable. Another shot of drier air pushes in overnight, and tomorrow’s weather looks even better. Enjoy!

High pressure to give more of us a rain-free day Thursday

/ August 25, 2021 at 9:52 PM

After scattered storms dotted the interior with downpours once again this afternoon, most of us get a rain-free Thursday as stacked high pressure and a lobe of (relatively) drier air filter into the area from the Atlantic. Temperatures look to head up to the upper 80s to around 90°, right around where we should be in late August. We’ll keep the relatively calm and quiet weather into Friday and the weekend as well, with upper 80s and just the standard slight chance of afternoon thunderstorms through Sunday.
