Below-normal temperatures will continue this week as we remain under in the influence of high pressure anchored to the northeast, with showers taking a break for a few days before returning to the forecast for the weekend.

A few lingering showers will be possible Monday morning with a stationary front nearby, though high pressure will continue to nudge that front further and further south, clearing us out for a couple nice days. Mostly cloudy skies keep highs capped to the low 80s on Monday after a mid-60s start, but we should see gradual reduction in cloud cover throughout the day. Tuesday looks to be rather nice, with lows in the mid-60s yielding to highs in the mid-80s under partly cloudy to mostly sunny skies. We’ll start to see the front to our south buckle a little more as low pressure — which is forecast to become Hurricane Francine — moves toward the Louisiana Gulf Coast during the middle of the week. This will net us an uptick in cloud cover and dewpoints for Wednesday, but we’ll get one more rain-free day in.

The high pressure center to our northeast that’ll give us a relatively quiet start to the week will be nudged eastward, which will allow the persistent stationary front to retreat a bit northward. This will bring an uptick in shower chances beginning Thursday and lasting into at least Saturday. It won’t rain all the time, but you’ll want to consider indoor plans as a backup to any outdoor plans. High temperatures will head down a bit with the uptick in cloud cover and showers, with highs in the low 80s expected Thursday and Friday before winds get a little more due-east, bringing some warmer temperatures back to the area for the weekend. Still, though, we stay below mid-September norms, generally running in the mid-80s Saturday and Sunday.

The final week of August will end on a warm and more humid note than the past 7-10 days have offered across the area. Storms will take a pause, though, as high pressure aloft puts a lid on widespread cloud cover, much less thunderstorm development, for much of the week.

The stationary front that’s kept shower chances in the neighborhood over the weekend still lingers nearby, and a shower or two will be possible (though unlikely) on Monday. Dewpoints will continue their steady climb, peaking in the mid-70s, which will make the upper 80s feel more like the mid-90s.

High pressure aloft will become more entrenched across the area starting Tuesday, setting us up for a rain-free stretch through Friday that will feature warmer-than-normal temperatures for late August. We should see highs peak in the low-to-mid-90s each afternoon, and with dewpoints peaking in the mid-70s, heat indices should head back into the 100s especially Wednesday-Friday. We’ll fall short of the Heat Advisory threshold of 108°, but it’ll still be plenty warm with just a few clouds to hide the sun from time to time. The high pressure pattern will keep winds generally light, too, so there won’t be much of a breeze, either.

As we head into Labor Day weekend, the high pressure ridge aloft gets shunted south and west as a trough digs in a bit to our north. This will kick up the chance for a few afternoon thunderstorms and take some of the bite out of the heat, but it’ll still be plenty warm as we bid farewell to summer as meteorological fall begins on Sunday.

Another break from the heat is in the offing this week as cooler high pressure works its way into the area. We’ll really start to feel it beginning mid-week, and it should last well into the weekend.

One front gets by early Monday, stalling out nearby. This should cut down on coverage of afternoon storms, at least, but a couple storms can’t be ruled out as highs head to the low-to-mid-90s. The cooling trend begins on Tuesday as highs top out around 90°, and will continue for the rest of the week as highs fall into the mid-80s with minimal afternoon thunderstorm chances. Lows will bottom out in the upper 60s fairly routinely as well, with even some mid-60s possible in less urbanized locations.

Temperatures start to warm again as we get into the weekend, but highs should continue to run generally in the mid-to-upper 80s with scattered thunderstorm chances each day.

Well, there will be decidedly fewer tropical cyclones impacting the area during the upcoming week, though we will still be living with flooding from Debby for the next few days along the Edisto and Ashley rivers as they continue to fall slowly from record (or very near-record) levels. We at least have something to look forward to as we head into the first school week of the year: some drier air punching in for late week.

The weather story this week is Tropical Storm Debby. Some rain associated with the system has already tried to push ashore Sunday evening, and there’s a lot more where that comes from as we get into the first few days of the new work week. The forecast continues to call for Debby to stall out and meander over Georgia, causing excessive rainfall that could lead to widespread significant flooding across the Lowcountry over the next several days. We will also deal with the potential for tropical storm-force winds, storm surge, and tornadoes as well. The slow-moving nature of the storm increases the uncertainty about exact numbers for impacts as well as on timing, but we’ll do our best here within the limits of the science.

After a really nice Sunday that featured dewpoints dropping into the low 60s and no rain to speak of, we get one more day of lower humidity before we return to the swamp for the rest of the upcoming week. For Monday, though, enjoy lows around 70° yielding to highs around 90° in the afternoon with dewpoints generally in the mid-60s. We’ll see a mix of sun and clouds throughout the day, but rain should just hold off to our west for one more day. (Can’t rule out some showers near I-95, though.)

I’m back…just in time for more rain. Showers and thunderstorms figure prominently in the forecast this week, especially in the afternoons and evenings, as the pattern generally keeps a trough in the east and a ridge in the west. This keeps us within southwest flow aloft, which keeps disturbances rippling through the area at times and the flow of moisture open from the Gulf. This, in turn, translates to potentially numerous showers and thunderstorms each afternoon and evening as daytime heating kicks in and the sea breeze makes its inland trek.

After reaching 99° at the airport on Sunday — the warmest it’s been since May 29, 2019, when it was 101° in the midst of the Memorial Day heat wave — air temperatures make another run for the upper 90s on Monday after another steamy start in the upper 70s to low 80s as a deep-layer ridge stays in place. Given the moisture in place, heat indices should once again reach or exceed Heat Advisory criteria (108°) in many spots, especially in the Highway 17 corridor. A few showers and thunderstorms will be possible once again Monday afternoon and evening along and ahead of the seabreeze, but with the ridge in place, coverage will be scattered at best. Much like Sunday, we can’t rule out a stronger storm where one does fire if it can realize the considerable instability that will be available to it. Additionally, storm motions should again be fairly slow, and with a juicy atmosphere, some localized flooding will be possible if a storm does fire and hang out for a bit.

A surface trough and the seabreeze keeps shower and thunderstorm chances in the forecast each afternoon for much of the upcoming week. We’ll stay on the steamy side, though, with temperatures generally in the low to mid-90s each afternoon and lows in the upper 70s inland to low 80s near the coast, where additional record high minimum temperature records could be broken this week.

We will get the first week of July off to a very soggy start as a front stalls in the area, bringing a risk for numerous showers and thunderstorms on Monday evening (more on that shortly). While rain chances back off a little bit Tuesday and Wednesday as the front meanders and weakens, we will get at least a brief break from the advisory-level heat that punctuated the end of June. Rain will keep highs to the upper 80s on Monday, while onshore flow Tuesday helps to keep highs tamped down to the mid-80s. Warming begins again Wednesday, though, with upper 80s yielding to mid-90s on the Fourth of July. We’re in the upper 90s for Friday and the weekend with standard afternoon and evening shower and thunderstorm chances expected.
