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.
A southward-moving cold front will bring about a bout of unsettled weather this weekend that’ll linger into next week with high pressure building back in from the northeast.
Warmer-than-normal temperatures will continue for the rest of the work week, with rain chances starting to tick up as we get toward Friday and the weekend.
After a beautiful weekend, the pattern begins to shift back toward warmer and more humid conditions once more, bringing about the return of shower and thunderstorm chances later this week into the weekend.
After a bit of a dreary and chilly day featuring a high struggling to 70° — the coolest day since we only topped out at 63° on May 2 — the sun returns to the forecast beginning Friday and lasting into next week.
High pressure wedging in from the northeast made for a much cooler day on Wednesday — the high only reached 77°, the coolest high since 76° on May 31 — and we’ll keep that going into Thursday. Winds kick up a bit more Thursday as low pressure begins to spin up offshore, tightening the pressure gradient across the area. There could be some showers within the wedge at any point during the day, but nothing too out of control by any stretch. The main hazards will be a risk for coastal flooding at times of high tide. The 6:40am high tide could touch 7′ MLLW, producing some minor flooding in the most vulnerable locations. The evening high tide, which peaks around 7:10 PM, will run more than a half-foot higher, with moderate coastal flooding expected. Be ready for road closures downtown during the second half of the commute.
The first legitimate shot of cooler air of the season begins to build in on Wednesday as high pressure starts to wedge into the area from the north. It’ll bring with it some breezy conditions and an elevated risk of coastal flooding that will last into at least Friday.
Low pressure aloft will drift northward into our neck of the woods on Tuesday, which should help kick up a little more in the way of showers and thunderstorms, especially in the afternoon and evening. It’ll be another warm and muggy start, with lows in the low to mid-70s across the area to start the day. Some guidance suggests storms appear possible near the coast to start the day, moving inland with time as the seabreeze pushes inland. The main concerns will be the potential for isolated flooding due to heavy rain from slow-moving storms and the risk for storms to produce strong wind gusts.
The week ahead gets off to a hot, humid, and unsettled start, but by the end of the week, temperatures will be more befitting of — if not a few clicks below — what we’d expect from late September.
Summer is far from finished with us yet. After a couple days with relatively drier air and slightly cooler temperatures, we’re back to the 90s on Friday as surface winds swing around a little more westerly than we’ve seen the past few days. It should be a mostly sunny day, though clouds will increase later in the day with the potential for a shower or two to potentially migrate in from the north late. At least we get off to one more seasonable start as lows take one more trip to the mid-60s before a stretch of 70s lows kicks off Saturday.
