With Imelda departing to our east, high pressure will wedge down across the area, ushering in some cooler and drier air that’ll be particularly noticeable on Thursday. Shower chances return for Friday heading into the weekend, though.

The pressure gradient between high pressure to the north and Imelda to the southeast will be tightening on Tuesday, and we should have a fairly breezy and seasonably cool day once again thanks to those northeast winds as well as cloud cover and a few lingering showers. Temperatures start around 70°, but should only warm to the upper 70s to maybe 80° depending on breaks in the clouds. The decaying coastal front will still be able to contribute to a few showers, but we should see shower chances diminish as we get through Tuesday and Imelda pulls further and further offshore.

There’s a chance that we could see some minor tidal flooding Tuesday afternoon courtesy of elevated water levels due to the onshore, northeasterly flow. The better chances for coastal flooding will begin Wednesday, though, and may be with us for a little bit as we head toward a full moon next week.

Warmer-than-normal temperatures will persist for the next few days, especially ahead of a cold front that will bring some fairly solid rain chances to the area for the first time in a little while on Friday.

A warming trend begins Tuesday as high pressure to the north continues to weaken and winds turn more onshore, ushering in a much more summer-like feel over the next few days. Temperatures Tuesday start in the upper 60s to around 70°, warming to the mid-80s in the afternoon with a mix of sun and clouds. Factor in the upper 60s-lower 70s dewpoints and it’ll feel more like 90°. Like we saw on Monday, a few afternoon showers are possible, though the weakening high also will portend a weakening coastal trough, which should keep the risk for showers relatively low.

There’s not too much to write home about weather-wise for Tuesday other than it will be a really nice mid-September day across the Lowcountry. Below-normal temperatures continue, with lows in the low 60s warming to the low 80s in the afternoon under mostly sunny skies. Dewpoints mix down to the mid-50s in the afternoon, making the warmth comfortable. Plus, water levels will fall short of flood stage Tuesday as we get further away from the full moon and the recent perigee, so there are no coastal flooding concerns for the rest of the week, either.

Another quiet weather day is ahead as high pressure wedges across the area from the northeast. Expect a mix of sun and clouds with comfortable temperatures. We start the day in the mid-60s, warming to about 80° in the afternoon. It’ll be a bit breezy, with winds gusting around 15-20 MPH especially near the coast. These northeasterly winds will continue to drive tidal departures in Charleston Harbor above flood stage, and we should see minor to moderate flooding with the 9:35 AM high tide. Some flooding may have impacts on the tail end of the commute, so be prepared for delays if downtown is your destination.

The rest of the work week will remain generally quiet (weather-wise, anyway), as high pressure remains in control at the surface. Temperatures will be on a warming trend as we get over the hump and into the second half of the work week as the mid-level trough that’s kept us on the cool side flattens out and retreats a bit north. We’ll also start to see high pressure build back in from the Atlantic for a few days, which turns the flow at the surface more southerly and starts to bring that more warm and humid air back to the area. We’re in the mid-80s Wednesday, upper 80s Thursday, and likely back to around 90° on Friday, with lows steadily climbing with the dewpoints back to around 70° by Friday morning. However, we look to stay rain-free through about Saturday before another front approaches for late weekend/early next week.

Mostly quiet weather is expected for the rest of the work week, with a warming trend taking us from the fall-like Labor Day weekend back to something a little more resembling summer by the end of the week, with highs back in the 90s by Friday.

Cooler and drier air will continue to push into the area overnight into Wednesday, yielding a well-deserved beautiful day across the Lowcountry with comfortable warmth and few clouds. We start the day in the mid-to-upper 60s, warming to the mid-80s in the afternoon. Dewpoints mixing down to the low 60s — and perhaps as low as the upper 50s — will feel quite good!

Dewpoints will continue to fall on Tuesday as drier air filters into the area, making for a comfortably warm day with plenty of sunshine to be had. We start the day in the low 70s, warming to the mid-to-upper 80s in the afternoon with just some fair weather cloud cover to be had. All in all, a welcomed nice day after yet another deluge in Mt. Pleasant on Monday.
