Thursday: A rather pleasant weather day

/ September 14, 2022 at 7:55 PM

We’ve got a really nice weather day coming up for Thursday. We’ll start the day in the mid-60s away from the coast (where the warmer water temperatures will keep lows above 70°). Temperatures will head into the mid-80s under mostly sunny skies with a northeasterly breeze keeping things feeling seasonable. Meanwhile, dewpoints will mix out to around 60°, making for a very comfortable afternoon. All in all, it should be a really nice day to get out and about a bit as you can — I’d certainly recommend it.

Pleasant weather will continue for Friday into the weekend, too. A coastal trough could help get a shower or two toward the area on Saturday and Sunday, but otherwise, expect rain-free conditions and seasonable temperatures.

Tuesday: Still warm, but turning less humid

/ September 12, 2022 at 10:15 PM

Ready for a break in the humidity? If so — as I suspect most of you are — it begins on Tuesday as drier air filters into the area throughout the day. We’ll see dewpoints fall from the low 70s to start the day to the mid-60s by sundown. High temperatures will still top out in the upper 80s, and it’ll still feel a little more like 90-91°, but overall, it’ll start to feel a lot better. There’s a small chance for a few showers to fire near the coast in the late afternoon, but the vast majority of us look to stay rain-free under partly cloudy skies.

It gets better from here, too: Wednesday morning will feel positively refreshing with dewpoints in the low 60s and air temperatures in the mid-60s away from the coast. It’ll also be the first day with zeroed-out rain chances all month. Should be an excellent day for an outdoor lunch or an evening walk. (Why not both?)

Rain chances within onshore flow creep up a bit starting Thursday as a coastal trough forms, but temperatures will remain a little more seasonable — not quite fall, but not quite blazing summer, either, as highs top out in the low 80s after morning lows in the upper 60s.

Sunday: Scattered storms expected, but no total rainout

/ September 10, 2022 at 8:52 PM

Expect another round of scattered showers and thunderstorms for Sunday as moisture continues to pump into the area from the Gulf and beyond. We may see some pre-sunrise showers and storms in the area to start the day, but the greater probability of precipitation will arrive in the afternoon as the seabreeze begins trekking inland and thunderstorms get rolling. Heavy rain and lightning will be the main concerns for any thunderstorm that develops. Once again, don’t expect it to rain all day at any one location — just be ready to move outdoor activities inside if thunderstorms approach.

Given the scattered cloud cover, expect temperatures to head into the upper 80s in the afternoon. Mix in the humidity, though, and it’ll feel closer to 100-102°. Given just how much rain has fallen in the last few days, too, grassy areas without much tree cover may be especially heinous.

Elevated rain chances continue for Monday, but we will start to see a bit calmer weather Tuesday and especially Wednesday before a front stalls out nearby Thursday, which will bring some scattered rain chances back into the picture — though right now, it looks nothing like we’ve been experiencing recently.

Thursday: Showers and storms developing in the afternoon; tidal flooding expected in the evening

/ September 7, 2022 at 10:07 PM

We transition back to a more active pattern beginning Thursday as a front gets through and stalls out nearby while the upper-air configuration aims a steady stream of moisture and disturbances at us for a few days. While it looks like we start the day mostly dry, expect showers and storms to develop in the afternoon and evening hours. Rain will be locally heavy at times, with the potential for isolated bouts of freshwater flooding. The increase in cloud cover and shower activity will help limit highs to the mid-80s, some 10° cooler than we’ve experienced the past couple days.

Tides will begin running well into flood stage in Charleston Harbor around the evening high tides beginning Thursday. Minor to moderate flooding is forecast Thursday evening around the 7:22 PM high tide, and this should be enough to close a few roads downtown regardless of any rain. If it rains heavily, of course, this will certainly lead to a more widespread flooding event, so we’ll be watching downtown closely on Thursday and over the next few evenings in general.

Rain chances continue to head up Friday into the weekend as precipitable water values surge well past 2″. The risk for flooding will increase accordingly across the area, and mixing in the higher tides, we could be in for a busy few days downtown. Stay tuned to forecast updates as we close out the work week and head into the weekend.

Labor Day: Dodging showers and storms from time to time

/ September 4, 2022 at 10:28 PM

Labor Day looks to feature an uptick in shower and storm coverage when compared to Sunday’s relatively quiet weather, but it still doesn’t look like a situation where outdoor plans will be totally washed out. After a little drier air worked its way into the area for Sunday, more moisture will move back in from the southwest for Monday. We could start the day with some showers and storms advancing northeastward across the area with some brief downpours embedded. Then, the seabreeze should kick in during the afternoon and help develop more showers and thunderstorms, which will progress inland with time. Heavy rain is the main concern from any thunderstorms; with precipitable water values over 2″, there will be a risk for flooding in a few spots where heavy rain repeats on itself. Of course, lightning will be a concern as well — as always, remember that if you’re hearing thunder, you’re in the strike zone. When thunder roars, go indoors!

Like the last few mornings, we’ll start in the low-to-mid 70s (warmer near the coast) and head toward the mid-80s in the afternoon outside of any showers and thunderstorms that develop. Mix in the humidity and it’ll feel closer to some very muggy mid-90s.

Bottom line: It won’t rain all day, but you’ll want to keep an eye to the sky in case conditions begin to head downhill. Be flexible with your outdoor plans and have a solid plan B in your back pocket.

Sunday: Still dodging scattered showers and storms

/ September 3, 2022 at 8:20 PM

Sunday’s forecast is essentially a matter of highlighting today’s weather, hitting Cmd+C, then Cmd+V (or Ctrl if you’re on Windows or Linux). Onshore flow will continue with the risk for scattered showers and storms throughout the day. Better rain chances will be found at the coast in the morning before transitioning inland with the seabreeze in the afternoon. Precipitable water values will remain at or above 2″, which will promote the risk for isolated downpours and perhaps flooding concerns if heavy rain ends up repeating over the same area. The diffuse stationary front which has been plaguing our surface pattern for the better part of a week now will wobble a little further southwest for Sunday, which should keep the more widespread rainfall in Georgia. Even still, though, stay flexible with your outdoor plans and be ready to move them inside quickly if storms approach.

Temperatures will once again follow today’s trend: lows in the low-to-mid-70s to start the day, with highs topping out in the mid-to-upper 80s before showers and thunderstorms set in. Heat indices will run in the mid-90s with the continued summer-esque humidity in place.

This pattern looks to continue into Labor Day and beyond. Aloft, ridging remains firmly in place over the next several days as an upper low cuts off over the Midwest. In the tropics, Tropical Storm Earl, which was named last night, will recurve well away from the US before it becomes a threat to land, while Danielle remains very far out in the Atlantic, an issue for shipping traffic and fish.

Saturday: Scattered storms as a stalled front lingers

/ September 2, 2022 at 9:21 PM

Saturday looks to bring another round of scattered showers and storms to the area, possibly as soon as sun-up as storms develop offshore and drift inland within onshore flow. During the day Saturday, a stationary front could wobble back north into the area, which may help focus additional shower and storm development in the afternoon. Unfortunately, the models are still varying quite widely on precipitation coverage during the afternoon and evening hours, so it’s going to be difficult to pinpoint exactly when and where it will rain until trends become apparent tomorrow. With that in mind, I don’t think it is wise to totally shelve outdoor plans, but I would recommend having a strong backup plan in your back pocket ready to go.

Thanks to onshore flow, lows on Saturday will run a couple clicks above normal (low to mid-70s) and highs will run a couple clicks below normal, generally running in the mid-80s in the afternoon ahead of any showers or thunderstorms that may develop. Mix in humidity and it’ll feel like the mid-90s.

We look to stay in this pattern through the Labor Day holiday, with variable rain chances each day driven largely by the positioning of the stalled front and the state of the atmosphere after any convection on the previous day. My advice remains the same: Don’t cancel plans, but be ready to change them.

Tuesday: More scattered storms, possibly another wet commute

/ August 29, 2022 at 11:08 PM

After a torrential deluge that closed numerous streets both in downtown Charleston as well as North Charleston, we should see a little less coverage of showers and thunderstorms for Tuesday, but more heavy rainfall will be possible. We could once again see some wet weather for tomorrow morning’s commute as another round of showers and storms skirts up the coast. Then, a more typical afternoon round of scattered showers and storms should fire up along the seabreeze as temperatures are expected to climb to the mid-to-upper 80s. Given the drenched soils from Monday’s rains, it may not take much to cause additional flooding problems on Tuesday where heavier rain falls, so that’ll certainly be something worth watching. Flooding rain, though, should certainly not be as widespread as we saw today.

We’ll continue to see a decrease in coverage as the week goes on, though scattered showers and storms will remain possible each afternoon, with a few stronger storms not out of the question Wednesday into Thursday. An uptick in coverage is possible Friday into Saturday depending on where a cold front stalls out — stay tuned for refinements.

Scattered showers and storms for Tuesday as a front stalls out

/ August 15, 2022 at 9:34 PM

Tuesday will begin a stretch of unsettled days across the Lowcountry as a cold front moves into the area and stalls out. This will help kick off showers and thunderstorms in the afternoon, with some heavy rain possible at times in the strongest storms. There are some indications in the high-resolution ensemble guidance that we could see heavy rain near the coast later in the evening as the boundary approaches; fortunately, we’ll be heading toward low tide during commute time. That being said, be ready for a little longer drive home.

Highs will top out near 90° before the onset of showers and thunderstorms; mix in low 70s dewpoints and it’ll feel around 95-97°. This is right around normal for mid-August.

Wednesday could run a little cooler and a little drier as the front could sag south of the area briefly before meandering back northward on Thursday. Likely rain chances will continue through the end of the work week into the weekend.

Tuesday: Another hot early-August day

/ August 1, 2022 at 9:41 PM

More warm and humid weather is on tap for Tuesday as air temperatures once again peak in the mid-90s after starting out in the mid-70s away from the warmer coastline. Mix in humidity and it’ll feel closer to the low 100s, especially as the seabreeze passes by in the afternoon. Rain-wise, it looks to be a fairly typical summer day. We could contend with a few showers in the morning near the coast, with primarily seabreeze-driven isolated shower and storm coverage in the afternoon. Storms will be able to produce some heavy rain and maybe a few strong wind gusts, but severe weather isn’t anticipated.

We could see a little better storm coverage on Wednesday before high pressure rebuilds later in the week. Temperatures will be trending down toward around normal for this point in the year as well, with highs around 90° each day from Thursday into next week.
