After our largely uneventful brush with Potential Tropical Cyclone Eight, we have a pretty nice weather day on tap for Tuesday as dry air wrapping around the back end of the system hangs around for one more day. We’ll start the day comfortably in the mid-60s, warming to the mid-80s in the afternoon under partly cloudy skies. Dewpoints run into the mid-to-upper 60s, so it’ll feel a little humid, but not too bad.
Cloud cover will continue on Thursday as moisture from Hurricane Francine, which has made landfall in Louisiana as a Category 2 storm with maximum winds of 100 MPH, continues to push northward across the Southeast and into the Lowcountry. High pressure will try to hang on across the East Coast, though Francine will continue to dislodge it north and east. Moisture moving atop high pressure will create plenty of clouds and may be enough to get a few showers going in the afternoon as well, though many of us should stay dry for one more day. We start Thursday around 70°, warming to the mid-80s in the afternoon despite the cloud cover.
Tuesday looks like a rather nice day in our part of the world with mostly sunny skies, a seasonably cool start in the low 60s, and highs in the mid-80s with relatively low humidity as high pressure’s influence on the area peaks before moisture returns starting Wednesday. I hope you can take advantage! Unsettled weather will return to the area by Thursday.
The wedge of high pressure that’s kept things breezy and cool but largely quiet hangs on for one more day Thursday. We’ll start the day in the low 70s, warming to the mid-80s in the afternoon under a mix of sun and clouds. Breezy conditions with gusts 20-25 MPH will continue to be possible as the pressure gradient stays pinched, and we’ll keep the risk of a shower or two primarily in the afternoon. The best chance for any rain will be closer to the coast, though much of us look to get the day in rain-free.
I hope everyone has gotten to enjoy the last few quiet weather days — it’s been warm, but aside from a brief shower in spots, mostly quiet. This begins to change on Labor Day as a cold front moves into the area from the north. We’ll see the risk for showers and thunderstorms increase ahead of the front, with rain chances peaking in the afternoon and evening. Severe storms are not expected, but some brief periods of heavy rain will be possible.
We’ll have one more day of seasonably warm temperatures before high pressure wedging southward drives some cooler air into the area for much of the upcoming week. Expect to start Labor Day in the mid-70s, warming to the upper 80s in the afternoon before showers and thunderstorms fire up. Heat indices should run around 100° given dewpoints in the mid-70s.
The rest of the week will feature below-normal highs in the low to mid-80s each day within a persistent northeast flow. Unsettled weather will continue, though, with the front stalled to our south and a coastal trough hanging around for the foreseeable future. It won’t rain all the time, but the risk will certainly be there. I’ll have more details tomorrow evening.
Our stretch of high-pressure-dominated weather continues on Thursday as warm temperatures and mostly sunny skies continue. We start the day in the mid-70s, warming to the mid-90s in the afternoon. Dewpoints in the low 70s will ultimately yield heat indices around 100-101°. A few patches of fog will be possible in the morning, but otherwise, another generally quiet weather day is expected.
High pressure will bring a pause in the rain and a further uptick in temperatures starting Tuesday. We start the day in the low to mid-70s (warmer near the coast), warming to the low 90s in the afternoon under partly cloudy to mostly sunny skies. With 70s dewpoints continuing their comeback, expect heat indices in the low 100s to return to the area as well — a fair bit warmer than we’ve been used to recently, but staying below the heat advisory thresholds we got to know very well during July.
We’ve got a reasonably comfortable day (especially as late August goes) for Thursday as cool high pressure continues to rule the meteorological roost in our neck of the woods. We start the day in the upper 60s in much of the metro, likely dropping even lower further inland and in more rural locations. Temperatures should warm to the mid-80s in the afternoon, but humidity will be quite tolerable with mid-60s dewpoints expected. Clouds will be on the increase as a coastal trough takes shape, and there will be a risk for a shower near the coast, but much of us get the day in rain-free.
Tuesday looks a lot like Monday did (in the weather department, anyway) as a front continues to meander nearby, keeping the risk for a few showers and thunderstorms in the forecast in the afternoon primarily east of 17-A. Temperatures will follow a similar curve as well — we start in the low 70s (warmer toward the coast) and warm into the upper 80s to around 90° in the afternoon.
As far as storms go, a few folks could see some locally heavy rain thanks to slow storm motions, but otherwise, no severe weather is expected.
Well, we are back to the heat — briefly, at least — on Sunday as dewpoints head back to the mid-70s ahead of a cold front that could bring stronger storms later in the day. Expect air temperatures to peak in the mid-90s, with heat indices in the mid-100s — shy of the Heat Advisory criteria of 108°, but not by much — at the height of the afternoon.
Attention will then turn to the potential for strong to severe thunderstorms accompanying the front in the late afternoon and evening hours. A thunderstorm complex is expected to develop in the Upstate and will head to the Lowcountry as the day goes on. Given the heat and humidity, the atmosphere looks to be capable of sustaining strong to severe thunderstorms with damaging wind gusts as the main concern. Heavy rain will be a secondary concern, but these storms should be moving fairly quickly so any ongoing flooding shouldn’t worsen. Be ready for conditions to change in a hurry tomorrow evening, and keep an ear out for possible watches and warnings.
