Friday and the weekend look mostly quiet as high pressure remains the main weather player for a few more days. We should start Friday in the mid-to-upper 60s in much of the metro (with low 70s on the coast); temperatures head to the low 90s in the afternoon under mostly sunny skies. With dewpoints in the mid-60s, the heat index could actually run slightly cooler than the air temperature (yes, this can happen!). So, while it’ll still be on the hot side, it won’t be quite as bad as it has been.

Winds go more southerly starting Saturday, and we’ll see a slow uptick in dewpoints as a result, but Saturday still looks quite good. We’ll start in the low 70s, warming to the low 90s in the afternoon under mostly sunny skies once again. Heat indices will run a degree or two warmer than the air temperature, but still generally not too out of bounds especially compared to what we’ve dealt with recently. Dewpoints creep back into the 70s on Sunday, and this will help drive a few scattered showers and storms in the afternoon and evening as another cold front approaches the area. We could see a stronger storm or two, but that’ll depend on the timing of the front. Overall, though, we should have a pretty good weekend of weather. And, given the fact that winds will go more southerly, the risk for coastal flooding is diminished for the upcoming weekend compared to yesterday’s forecast, though a little salt water on Fishburne at Hagood around the evening high tides could still be in play.

High pressure wedging southward across the area has brought some cooler and drier air to the area this evening, with dewpoints falling into the mid-60s (it’s been a minute!). This will yield a fairly nice (but still warm) day on Thursday. We’ll start the day in the low 70s and warm to the upper 80s in the afternoon under partly cloudy to mostly sunny skies. With the lack of moisture and influence of high pressure, rain isn’t expected (and won’t be for a few days). Overall, not too shabby for mid-August!

We have a bit of a respite from the rain and the extreme humidity on the way as a front slides south of the area and stalls tonight. Some lingering moisture and a trough of low pressure will allow for a few storms to remain in the forecast on Wednesday, though, as dewpoints slowly drop through the low 70s throughout the day. We start the day in the mid-70s and warm to the upper 80s in the afternoon, capped by some of that cooler and drier air trying to move back in. Expect the best chance of showers and storms from roughly 2-10PM. A few downpours can’t be totally ruled out as the deeper moisture only really starts to scour out Wednesday night, so a flood advisory or two could still be possible.

Tuesday’s forecast will continue to feature warm temperatures and afternoon thunderstorms as Berkeley and Charleston head back to school. We have another warm start ahead of us — generally expect lows in the upper 70s once again, followed by highs in the low 90s in the afternoon. This should run a couple degrees cooler with a little more onshore flow, but it’ll still be toasty with heat indices peaking around 102° before showers and storms fire. Once again, heavy downpours could cause localized flooding, especially near swollen rivers and streams and in urban areas, so stay alert for possible Flood Advisories.

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 first weekend after Debby will be a sweltering hot and occasionally unsettled affair as a front stalls out to our west and the seabreeze helps to kick off afternoon showers and thunderstorms. Expect to start Saturday in the upper 70s, warming to the mid-90s in the afternoon. Lingering tropical moisture characterized by dewpoints in the upper 70s will drive heat indices into dangerous territory well into the low 110s. We could flirt with Excessive Heat Warning criteria if it wasn’t for the expectation that showers and thunderstorms would fire on the seabreeze by midafternoon. Unfortunately, we may see yet another round of heavy downpours for places being impacted by the ongoing flooding in the wake of Debby, and so it appears the Flood Watch will continue through at least 10am Saturday. Folks around Ridgeville, Moncks Corner, and Huger will need to continue to monitor for possible Flash Flood Warnings. We should see another round of showers and storms fire on Sunday with a similar setup in place to Saturday, too. Air temperatures may be slightly lower, but heat indices will still run close to 110°, so we will continue to swelter throughout the day Sunday. A front will squeak through next week, though, and that should allow for a little bit cooler and slightly drier air (72° dewpoints vs. 78° dewpoints, so don’t get too excited) to get into the area. So, it won’t last forever. Hang in there.

While Debby shuffles off to the northeast, our weather will remain unsettled as a trough persists aloft across the eastern half of the country. This will drive a surface front just close enough to stall out and keep elevated shower and thunderstorm chances in play each afternoon.

We returned to the 90s on Thursday and will head back there each afternoon for the foreseeable future. Lingering tropical moisture in the wake of Debby will help drive heat indices well into the 100s, perhaps flirting with advisory criteria despite low 90s air temperatures. Then, we should see showers and thunderstorms fire up each afternoon generally along and ahead of the seabreeze. Storm motions will generally be eastward, so some rain could spread to the coast.

All Tropical Storm Warnings were dropped this morning as Debby, which made landfall around Bulls Bay at 2am, continues to lift north away from the area. The risk for flooding continues, especially near rivers, creeks, and streams. An Areal Flood Warning remains in effect across the entire Tri-County area through at least 2:45pm. Additional rain should develop courtesy of some wraparound moisture from Debby as we get into the heat of the day, which could inhibit recovery from flooding, so the warning continues. The Flood Watch continues until Friday morning as well.

Temperatures today will run in the upper 80s, closer to normal after a record cool high temperature of 80° on Wednesday. We’ve seen some peeks of sun and blue sky this morning and should hopefully see a bit more of that just for our spirits’ sake. The sun will make a more complete comeback for Friday and the weekend.

Tropical Storm Debby will make landfall on the South Carolina coast somewhere around Bulls Bay up to Georgetown (taking the cone literally, the margin for error is between Mt. Pleasant and Myrtle Beach) overnight as it turns northward in response to high pressure building back in from the east. This landfall likely won’t really come with much fanfare as Debby’s inner core was hollowed out by land interaction and dry air over the past day or so. The strongest winds, in fact, are well away from the center of the storm. Still, there’s a risk for tropical storm-force winds at the coast and within gusts in rain bands, so the Tropical Storm Warning continues. With such saturated soils, it won’t take too much in the way of wind to bring trees down, so we’ll want to stay a little vigilant about possible power outages.

Showers with occasional downpours and some gusty winds to around 35 MPH have been commonplace throughout Wednesday and that should continue into the overnight through Thursday. Another inch-plus of rain should fall overnight through Thursday morning in the metro proper, with upwards of 2″ possible further inland (generally north and west of 17-A) where a fairly persistent rain band has been parked for a fair bit of the day.

We should see generally improving conditions on Thursday. Some spots may get another half-inch of rain or so as Debby begins to depart the area, and it’ll still be a little breezy, but overall, Debby’s effects will be winding down. Expect temperatures on Thursday to run a little warmer than they have in previous days, heading into the mid-to-upper 80s in the afternoon as the cloud shield begins to thin out.

Tropical Storm Debby will continue to figure prominently in the forecast as we head through the middle of the week with continued periods of heavy rain and gusty winds before a more standard summertime pattern once again starts to take hold Friday.
