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 warm front will lift north across the Lowcountry on Wednesday, putting an end to this stretch of below-normal temperatures and getting us in the warm sector of the next storm system which will affect the area Thursday before clearing the area Friday morning, yielding a docile finish to the work week.
High pressure remains in control on Tuesday as it builds southward and down the East Coast. With the high centered to the north, winds will shift around more easterly and come in off the ocean. As a result, high temperatures will run cooler tomorrow thanks to the onshore flow as well as the loss of the downslope component to the wind that we get when it blows out of the northwest. Relative humidity values will be higher (though not uncomfortably so), making for much less fire danger for tomorrow and for the rest of the week.
Tuesday will be the last day of below-normal temperatures; a warm front will lift north of the area on Wednesday, sending temperatures back well into the 70s. Our next rain chance still looks timed for sometime Thursday afternoon and evening, all depending on the forward progress of a cold front. Severe weather appears quite unlikely at this juncture, but we’ll continue to keep an eye out for changes. Regardless of any severe storms, Thursday looks to be a rather windy day, with gusty winds continuing into Friday.
Bridge Runners, so far so good for the race, rain-wise, but we’ll be keeping a close eye on the potential for some storms at times this weekend. Stay tuned as the forecast gets further and further fine-tuning.
We’ve got a day or two more of chilly weather (for late March, anyway) before temperatures rise quickly on Wednesday as a storm system approaches the area. From there, a stalled front provides additional opportunities for rainfall over the weekend.
Our stretch of cool and fair weather continues into Monday at a minimum. There will be actual clouds in the sky on Monday, generally of the high variety as a little moisture squeezes out around the base of the trough that’s brought us this very chilly weekend. Temperatures will remain on the cool side, bottoming out in the 40s in the metro area and perhaps the mid-30s in more rural areas, prompting a Frost Advisory for Inland Berkeley County.
A warm front will approach the area on Tuesday, allowing for more cloud cover to develop. It’s not clear just how far north said front might get yet; the current forecast is for temperatures to once again top out in the upper 60s, but it’s possible that the afternoon could run a touch warmer if the front is able to make a little more headway.
Wednesday will offer one more rain-free day before the storm system gets into the area. By then, the warm front will have lifted north of us, with highs in the upper 70s to low 80s running in stark contrast to what we’ve experienced over the past few days.
The next appreciable rain chance arrives Thursday afternoon and evening with a cold front; rainfall looks likely with some rumbles of thunder, but the higher severe weather risk is displaced to the north with the better dynamics. We’ll get a break in the rain on Friday, but with the front stalling out to our southwest, shower and storm chances remain in the picture through the weekend. Temperatures, meanwhile, will remain a little above normal.
We’ve got a very nice weekend coming up, especially for those of you who prefer temperatures a little on the cooler side. A series of dry cold fronts will swing through, ushering in progressively cooler airmasses each day this weekend. Saturday will find temperatures starting in the mid-40s, headed to the upper 60s in the afternoon with some downslope flow and March sun angle helping to counteract the cool advection. Winds may turn gusty at times, with gusts to 30-40 MPH certainly possible, so be aware of this if you have any outdoor plans or need to drive a high-profile vehicle.
Another front swings through early Sunday, sending low temperatures into the low 40s before rebounding to the mid-to-upper 60s in the afternoon again under largely uninterrupted sunshine. It’ll be a little less windy on Sunday, but gusts still could reach 25-30 MPH at times.
Looking ahead, one more front comes through Monday before a warming trend begins across the area. Expect temperatures to rebound to the mid-70s by Tuesday and into the low 80s by Wednesday. Our next meaningful rain chance doesn’t show up in the forecast until Thursday. While the rain we got Wednesday and Thursday certainly helped, there’s still a good bit of ground to make up rain-wise to get us out of drought. That being said, I won’t complain about sunshine and comfortable temperatures, either. Enjoy!
After some much needed rain Wednesday into Thursday, cooler and drier air builds back into the area for Friday and the weekend thanks to a series of cold fronts. Highs will top out in the low 70s on Friday with a mix of clouds and sun ahead of Saturday’s front, which will scour those clouds out and kick temperatures down a couple degrees, capping highs in the upper 60s to around 70°. Another reinforcing cold front gets through late Saturday into early Sunday, knocking temperatures back even further into the low 40s to start before only rebounding to the mid-60s in the afternoon despite full sunshine.
Through all of these frontal passages, expect gusty winds. Winds could gust upwards of 25-30 MPH on Friday, with gusts reaching or even exceeding 30 MPH on Saturday. Breezy conditions should also persist on Sunday as well. Keep this in mind if you have any outdoor activities planned, particularly those that involve tents or inflatables.
Fair weather persists into the upcoming work week, too, as a warming trend commences with highs approaching 80° by next Wednesday.
Much-needed rain will continue to fall for a good bit of today across the Charleston metro as a cold front slides eastward across the state. Said front will help to keep temperatures pretty steady-state throughout the day — we aren’t too far off from the NWS forecast high as of this writing (9am Thursday). No severe weather is expected, but we may yet hear a few more rumbles of thunder.
Rain will gradually taper off as we get into tonight, but showers may linger into early Friday morning. If you’ve got outdoor plans this evening, you may yet want to execute the indoor plan just to keep folks dry.
An unsettled period begins on Wednesday as our next storm system approaches the area. This storm system could aid in producing a few strong to severe thunderstorms in the afternoon.
A warm front will cross the area overnight, and as a result, Wednesday starts out with lows bottoming out just around 60° around the area. The Gulf will be open for business with a plume of warm, moist air overspreading the Carolinas ahead of a cold front. This should keep a fair bit of cloud cover around, but despite this, temperatures could still approach 80° in the afternoon, particularly if we get some peeks of sun mixed in during the day.
The morning appears to be dry, but it isn’t out of the question to see some showers try to get going ahead of the main event. With that in mind, though, the vast majority of guidance members are keeping things dry until the afternoon. The best chance of showers and thunderstorms could arrive in the form of a squall line in the evening. Instability should be modest at best, but ample wind shear could be enough to produce a few damaging wind gusts if storms can stay organized. Hail and even a tornado can’t be ruled out, either. As usual for our neck of the woods, the available instability will modulate the severe threat. Most of you shouldn’t see any severe weather tomorrow, but in case it does threaten, you’ll want to know about it: have reliable ways to hear watches and warnings, and be ready to move to a safe place if a warning is issued for your location.
Rain should continue well into Thursday as the front and moisture hangs around before finally moving away early Friday. Regardless of any severe weather, the rain will be quite nice to wash away some pollen and help chip away at the drought. The reward will be pretty sweet, too: a gorgeous Friday and the weekend, with fair weather continuing well into the following work week.
High pressure will continue to slip offshore overnight into Tuesday, allowing warmer and a little more humid air to keep working its way into the area. We stay rain-free on Tuesday, though, despite an increase in cloud cover. Highs top out in the mid-70s. Perhaps it won’t be the most picturesque day like we’ve had over the past couple days, but it will certainly be another decently nice day across the area.
Attention then turns to Wednesday, where there remains a risk for some severe storms that’s largely conditional on the timing of a cold front coming through the area. We’ll have the shear in place, but once again the question is instability and whether it will be available by the time forcing for ascent arrives. If the front gets closer earlier in the day, that could provide the necessary trigger for thunderstorms to develop and take advantage of that energy (though the amount of energy that would be available doesn’t look overly impressive). If it’s later in the day, though, we’ll see that instability begin to wane; as a result, the severe threat could be tempered somewhat. We should get some more clarity on the timing issues tomorrow; for now, prepare for a wet Wednesday with the potential for a few strong to severe thunderstorms. Hail, high winds, and a tornado are all on the table if in fact storms can get cranking, but as we know from recent days, that can be a big if. Stay tuned…
The week ahead will be bookended by really nice weather, though we’re going to need to get through another risk of showers and thunderstorms — yes, with a few possibly being severe — on Wednesday before we get through to the weekend.
For Monday, though, expect a slightly less windy carbon copy of Sunday. After starting in the mid-40s, highs will topping out in the low 70s under mostly sunny skies as cool and dry high pressure hangs on for one more day. We’ll see temperatures begin to head back up on Tuesday along with cloud cover as high pressure slips offshore in advance of our next storm system on Wednesday.
Wednesday will once again test our stretch of good luck with severe weather threats so far this spring. We’ll see a warm front lift across the area in the morning, putting us (at least briefly) in the warm sector of a strong storm system which is forecast to bring significant weather impacts to the Gulf Coast over the next two days. While in that warm sector, temperatures look to warm to the upper 70s despite decent cloud cover. Early calls from the models show decent instability and ample shear supportive of a slight severe weather threat. Given the close proximity of the front, I’d expect a more linear storm mode with damaging straight-line winds the primary concern, but there seems to be enough low-level shear to support a low-end tornado threat as well. Even outside of thunderstorms, winds look to be rather gusty courtesy of a strong low-level jet moving across the area. So, you’ll want to keep an ear out for forecast updates for the next couple days as the details are worked out.
Exact timing on the front’s passage will still need to be worked out, but overall, expect rain chances to trend downward as Thursday goes on. The front will leave behind a rather pleasant airmass with plenty of sun, low humidity, and high temperatures running near normal (low 70s) for Friday and the weekend. And so it goes with spring — some really nice weather mixed with the occasional nastygram.
After a somewhat confounding weather day on Saturday, Sunday’s forecast is much higher confidence with high pressure building in behind a cold front that will swing through overnight. This’ll cool things off nicely, with highs topping out around 70° under sunny skies and low humidity to boot. It’ll be a nice day to get out for a walk or get some yard work done. This will kick off a stretch of a couple days of quiet weather before our next storm system arrives by mid-week, bringing us another shot at showers and thunderstorms for the second half of the work week. (We still can very much use the rain.)
