The week ahead gets off to a hot, humid, and unsettled start, but by the end of the week, temperatures will be more befitting of — if not a few clicks below — what we’d expect from late September.

An upper low stalling out over Florida combined with an approaching (then stalling) front will help turn things a little more unsettled this weekend.

A front coming through on Tuesday will knock temperatures back from the record levels of the past two days, bringing some breezy conditions and maybe some coastal flooding in the process. We start the day in similar fashion to the past couple days, with lows in the mid-70s expected. High pressure building south will swing winds around to the east and northeast in the morning, turning things gusty in the process (especially at the coast). This wind may also help drive tidal departures higher, perhaps causing some minor coastal flooding with the midday high tide. Widespread flooding issues are not expected, though. We will see dewpoints begin to drop during the afternoon with highs peaking just in the upper 80s, right around mid-September normals.

Late-summer heat and humidity continues to build as temperatures look to return to the 90s for Thursday after a balmy start in the mid-70s. We should see a bit more in the way of afternoon showers and thunderstorms on the seabreeze with high pressure beginning to weaken, though not everyone will see rain, either. A few pockets of heavy rain will be possible with moderate instability and precipitable water values (generally the amount of water you could wring out of a column of air) a little over 2″.

There may be one more round of salt water flooding with Thursday evening’s high tide around 8:18 PM, but it’ll be on the minor side with water levels peaking in the 7-7.2′ range. Rain shouldn’t be an issue as the seabreeze will be well inland by that point, though. From here, we should see diminishing astronomical influences and less of a chance for coastal flooding, though there remains an outside shot on Friday coincident with the full moon.

Summer won’t loosen its grip just yet, especially as we head into Friday and Saturday as a front approaches the area, sending air temperatures back to the mid-90s and heat indices close to heat advisory territory.

Thursday looks to generally be a repeat of Wednesday (weather-wise, anyway). We’ll start the day in the mid-70s once again, warming to the low 90s in the afternoon. Mid-70s dewpoints will help drive the heat index into the upper 90s to around 100° — not quite August, but getting long in the tooth. The day should be primarily quiet with partly cloudy skies expected, though like we saw roll through Moncks Corner on Wednesday, a stray shower can’t be totally ruled out.

Highs in the 90s will continue over the next few days with plenty of sunshine as high pressure aloft remains the dominant weather feature.

The first day of September marks the beginning of climatological fall, but it certainly won’t feel that way with a stretch of 90s coming up. Tuesday starts this streak, with highs expected in the low 90s after a low-to-mid-70s start. Ridging aloft will continue to build over the area, and that should suppress much in the way of shower and thunderstorm development in the afternoon, though a stray popup isn’t out of the question.

A very warm climatological summer — perhaps a top-three warmest on record — comes to an end on Monday as we roll into September. It won’t feel like fall, though, as temperatures head back to the mid-90s as clouds and showers give way to sunnier skies.

Unsettled weather continues this weekend with plenty of moisture remaining available across the area and a front to the west, though we should start to see a downtick in rain coverage starting Sunday as high pressure begins to rebuild aloft and that front falls apart.
