Quiet weather continues for the next several days as high pressure and drier air aloft keep any risk for precipitation very, very low. We’re also staying hot: we reached 91° today and look to do similar numbers for Wednesday under mostly sunny skies. Thursday will be even warmer, with highs reaching the low-to-mid-90s and humidity pushing the heat indices a few degrees warmer.
The heat will break, though, as a cold front swings through late Thursday/early Friday morning. This cold front is legit (and has a great sense of timing, with the autumnal equinox occurring at 9:03 PM Thursday), with a cooler and drier airmass working into the area that’ll knock high temperatures down 10-15° over the previous day. The current NWS forecast doesn’t even crack 80° on Friday! Feels like forever since we’ve had a high that low without any rain, and it will feel quite nice leading into what’ll be an exceptional weekend of weather with mostly sunny skies and seasonable, below-normal temperatures. Hang in there…relief from the heat is coming!
A cold front is working its way through the area this evening which will usher in some positive changes for our weather as we close out the work week.
First thing you’ll notice on Wednesday morning is that it’ll almost feel a little more like fall (away from the coast, anyway — the warm water temperatures will blunt the cooldown some there). Expect lows in the mid-60s to start the day; dewpoints in the low 60s will feel fairly amazing coupled with those temperatures. Highs head to the mid-80s in the afternoon under partly cloudy skies with a northeasterly breeze. Rain chances are very minimal, though the happy hour NAM was a bit intrigued with the idea of a few seabreeze popup showers in the afternoon. This seems to be an outlier solution, though.
Winds turn a touch more easterly on Thursday, which could expose the coastal areas a bit more to the potential for a few showers and storms to drift ashore. This’ll depend on where the front ultimately stalls out, and the probabilities for precipitation remain rather low in general. Otherwise, skies will once again be partly cloudy; lows will run in the upper 60s and highs in the mid-80s with continued comfortable dewpoints.
Friday looks to feature a little bit more in the way of sunshine, though northeasterly winds will keep warmth from running wild as we top out once again in the mid-80s after a nice start to the day with lows just below 70°. Rain chances are once again so low as to be unmentionable, though we’ll want to continue to monitor trends with the front and any waves that might try to form along it.
Overall, though, a solid close to the work week as we emerge from a drencher of a few weeks. Good-looking weather continues into the weekend, too as high pressure continues in place over the area. The only potential fly in the ointment could be a coastal trough that looks to take shape, which may provide a focal point for a few isolated showers in the afternoons, mainly near the coast. We’ll watch trends, but in the meantime, enjoy the tiny sniff of fall — it’s better than what we’ve had, that’s for sure…
We will get one more day of relatively sparse thunderstorm coverage on Wednesday before the pattern becomes more active again starting Thursday. Highs will once again head into the low 90s across much of the area, and a few mid-90s readings can’t be ruled out either. 90s should reach all the way into downtown once again, too, as westerly winds pin the seabreeze to the immediate coast. As mentioned, a shower or storm can’t be ruled out in the afternoon and evening hours, with the best rain chances inland near an advancing cold front.
On Thursday, a strong influx of Gulf moisture opens up across the area. This, combined with the aforementioned front coming through and subsequently stalling out, will keep us quite unsettled as we head into the weekend. Temperatures will be modulated back to the mid-80s as numerous showers and thunderstorms should develop by afternoon. Friday remains unsettled as well, and some guidance suggests that could be a particularly rainy day, perhaps suppressing highs to the low 80s at best.
We will need to keep an eye on Thursday and Friday evening’s high tides for the potential for salt water flooding, too. Onshore flow combined with the upcoming full moon should drive water levels over 7′ each evening. These tides combined with the potential for heavy rain could spell another round or two of trouble for downtown Charleston — certainly something that will be watched quite carefully over the next few days. Stay tuned for forecast updates as rain timings and amounts become a little clearer as we get those soggier days into range of the higher-resolution model suite.
We’ll get a break in the more widespread rain as we head back to work and school on Tuesday as the surface configuration briefly turns a little more summer-like. We won’t stay completely rain-free — isolated to widely scattered showers and thunderstorms will be possible in the afternoon — but it certainly will be a bit of a shift from where we’ve been. The lower shower and storm coverage means temperatures will head to the low 90s in the afternoon; mix in the humidity and it’ll feel closer to 101-102°. We’ll repeat this on Wednesday before another front moves into the area by Thursday. Said front will once again stall out nearby — just not enough oomph yet to get these through at this point in the season — and keep us very unsettled from Thursday through Friday and into the weekend. This will send temperatures down to the upper 80s on Thursday to the low 80s on Friday with numerous showers and thunderstorms expected each afternoon. Heavy rain will be possible, and we may not get out of this week without another bout with flooding somewhere in the metro. Stay tuned to forecast updates.
As we head into mid-week and look to round the corner toward Labor Day weekend, we’re going to see a reduction in shower and thunderstorm coverage for a few days as some drier air aloft works in from the north and west. We’ll keep isolated to scattered shower and thunderstorm chances in the forecast as those probabilities won’t be totally eliminated, particularly near the coast, but we shouldn’t see the sustained flooding rains that have been a concern the past couple days. Areas further inland could even see a rain-free couple days, especially on Thursday as a front clears the area and stalls to our south.
As rain chances diminish, temperatures turn back up to a little above normal as we close out August and enter September. Expect highs around 90° for Wednesday; mix in the plentiful humidity and it’ll feel closer to 100-102°. Thursday will run pretty warm, too, with highs around 90° and heat indices in the upper 90s once again expected. Rain chances begin to tick back up on Friday, and that’ll lead to high temperatures topping out a little lower than the previous couple days, generally in the mid-to-upper 80s.
Unsettled weather looks to continue as we close out the work week. Wednesday will represent a little break from more of the widespread rain that we’ve seen of late. However, the atmosphere is still plenty juiced, and daytime heating will help fire off scattered showers and thunderstorms as a result. Bouts of heavy rain are expected, and more flood advisories are possible.
Rain chances head back into the likely category Thursday and Friday as another front moves into the area along with some energy rippling in aloft. Numerous to widespread showers and thunderstorms should redevelop each afternoon, with the threat of heavy rain and maybe some flooding continuing to loom. Exact timing on where and how much it will rain is impossible to know this far out — just know that some of you could see some very heavy rain, while others may see lighter amounts overall.
Temperatures will remain suppressed to the mid-80s each afternoon thanks to cloud cover and nearby showers and storms. Mix in humidity, though, and it’ll feel like the low to mid-90s especially if and when the sun peeks out from time to time.
Looking for rain relief this weekend? I wouldn’t bet on it; we’ll still see decent coverage of showers and thunderstorms especially each afternoon heading into next week. At least temperatures will remain capped in the mid-80s, which doesn’t feel so bad at this point in the year.
Unsettled — but somewhat cooler — weather continues this week, particularly Thursday into Friday as areas of low pressure along a lingering front as well as impulses around a persistent upper trough help enhance rain chances across the area.
Wednesday will be the driest of the set. As of this writing, the front is driving southward into Georgia, and should stay to our south for much of the day, keeping us in cooler and slightly drier air. While this won’t totally suppress the risk for afternoon showers and thunderstorms, it certainly will keep coverage generally isolated to scattered at best for the first day of school in Charleston County. Highs will top out in the mid-80s, which should make for a reasonably nice day all things considered (though dewpoints around 70° will still feel muggy).
Rain chances begin to ramp up late Wednesday night into Thursday as surface low pressure moves along the front, drawing the boundary a little more north. At the same time, the trough aloft pivots enough to put us in the right entrance region of a jet streak, helping to enhance lift. This combination will make for an unsettled Thursday, with scattered to numerous thunderstorms expected across the area. Heavy rain will be a concern, and we’ll need to keep a close watch for isolated flooding potential. The widespread rain and onshore flow just behind the stalled front should keep Thursday’s high temperatures suppressed to the low 80s.
Friday will run a touch warmer (mid-80s) with a little less coverage of storms to start the day, but showers and thunderstorms become likely in the afternoon after mixing some daytime heating in along with the specter of additional disturbances rounding the base of the upper trough and the persistent stalled front. Heavy rain will once again be a concern with the strongest storms.
This unsettled pattern looks to persist into the weekend as the front continues to meander and weaken, while temperatures turn warmer, closer to mid-August norms.
After a relatively quiet Tuesday, we’ll start to see rain chances trend back up starting Wednesday as a trough develops aloft and a cold front presses southward, which will eventually stall out somewhere in the area over the weekend. We still stay quite warm Wednesday into Thursday as highs top out in the low 90s and heat indices top out in the low 100s. Isolated to scattered showers and storms should develop along the seabreeze in the early afternoon and move inland as the day progresses. Same deal for Thursday, though we could see some additional coverage sprout up as the trough digs in a bit more down the East Coast and the front starts to drive southward a little more. By Friday, the front will be getting closer, and this will instigate greater shower and storm coverage as a result. Temperatures will also run a little cooler — by cooler, I mean upper 80s instead of low 90s — thanks to the more widespread cloud cover and rain coverage.
Heading into the weekend, we look to stay unsettled for at least part of Saturday, but drier air will be punching into the area. We should see a taste of mid-60s dewpoints starting Saturday afternoon, leading into what should be a rather gorgeous (by mid-August standards) Sunday. Fingers crossed these trends in the models continue — typically, it is still tough to get fronts this far south at this point in August, but then again, July’s deluge courtesy of southward-pushing fronts showed us that this hasn’t been a very typical summer. Stay tuned.
We’ll be closing out the last work week of July with a good bit of heat as high pressure dominates the weather pattern. Air temperatures will run into the mid-90s each afternoon, while humidity on top will make it feel well into the mid-100s. While heat indices will not reach the post-July 1 heat advisory criteria of 110°, it’ll still be enough to elevate the risk of heat-related illness. Make sure you’re getting plenty of fluids and taking plenty of shady breaks during the heat of the afternoon if you must be outdoors. Low temperatures will run quite warm as well, only bottoming out in the upper 70s away from the coast. Downtown and coastal communities may not see lows dip below 80° for several days. This lack of any real cooling off can add to cumulative heat stress over time.
The aforementioned high pressure will keep afternoon showers and thunderstorms to a minimum, with only isolated coverage expected along and ahead of the seabreeze on Wednesday and Thursday, with unmentionably low rain chances on Friday. It’s hard to stay totally rain-free this time of year, but don’t expect much out of storms over the next few days.
Our warm and occasionally stormy pattern stays in place of the rest of the work week as we remain under the influence of a broad trough aloft. Wednesday will yield another stormy afternoon with a low-end severe weather risk as a disturbance in the mid-levels moves across the Carolinas; if a storm turns severe, damaging wind gusts would be the main issue. Otherwise, it’s another hot and humid day — highs top out around 90° in the afternoon with heat indices once again peaking around 100-102° before storms develop and disrupt the temperature curve.
Thursday should run a little quieter with a little less mid-level energy in play, but we’ll still see the usual spate of isolated afternoon showers and thunderstorms along and ahead of the seabreeze. Temperatures will run a little warmer Thursday, with air temperatures in the low 90s and associated humidity yielding heat indices running around 105° in the afternoon. A cold front will sink southward toward the Carolinas on Friday; this will make showers and thunderstorms in the late afternoon and evening hours a little more likely. Temperatures on Friday continue in the low 90s with heat indices in the low to mid-100s.
Rain chances look to taper off as we get into the weekend, with scattered storms possible Saturday and more isolated storm coverage than we’ve seen in a little while expected on Sunday. It’ll stay muggy with lows in the mid-70s and highs in the low 90s each day.
