Friday & the weekend: Quiet and warm

/ September 19, 2024 at 11:11 PM

High pressure ridging in at the surface and aloft will make for a quiet and warm weekend of weather across the Lowcountry.

Clouds will still be around Friday as one more piece of energy ripples through before the high pressure ridge takes over. Rain isn’t expected, though a shower can’t be completely discounted. Expect highs in the mid-80s after an upper 60s start.

Despite the autumnal equinox on Sunday, the weekend will feel increasingly more like summer as highs climb into the mid-and-upper 80s each afternoon Saturday and Sunday. The high pressure ridge aloft will also keep a lid on much in the way of showers and thunderstorms (much less cloud cover). Not the worst set of days for an offseason beach visit, IMHO.

Thursday: A few stray storms; quieting down over the weekend

/ September 18, 2024 at 7:31 PM

We’ve got one more day of unsettled weather as low pressure aloft and at the surface mosey their way on out of here ahead of what should be a nice weekend. After a generally nice start in the upper 60s, a mix of sun and clouds will send temperatures up to the mid-80s in the afternoon before a few showers and thunderstorms break out with the heating of the day. Not everyone sees rain, but some heavy downpours will be possible in a few spots once again. Severe weather is not expected.

Rest of the work week: Slight storm chances return, followed by a cooldown

/ September 17, 2024 at 6:11 PM

After a beautiful Tuesday — I’m sitting outside as I write this, in fact — we will see a bit more in the way of moisture work its way into the area over the next couple days. It’ll also turn a bit warmer, with highs in the upper 80s Wednesday and solidly in the mid-80s on Thursday.

There will be the risk for some afternoon showers and maybe a thunderstorm each afternoon over the next couple days as a front gets closer. The risk for rain is slightly higher on Wednesday as the front gets through the area.

Once that front gets through, though, a stretch of excellent weather will begin. Friday begins a stretch of several days of temperatures at or below normal, with partly cloudy to mostly sunny skies each day through at least the middle of next week as high pressure takes command of the local weather situation. Should be quite enjoyable!

Tuesday: Pretty nice day on the heels of PTC Eight

/ September 16, 2024 at 11:29 PM

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.

The week ahead: Turning warmer, but first, a little tropical mischief

/ September 15, 2024 at 5:50 PM

The area of disturbed weather along the lingering stationary front we’ve been watching for a few days off the coast has been tagged as Potential Tropical Cyclone Eight this evening, prompting a Tropical Storm Warning from Edisto Beach to Ocracoke Inlet, NC, including the Charleston metro area. It brings with it some breezy rain and an increased coastal flood risk for Monday, but is not expected to be a high-end event for the Lowcountry. Its stay will be brief, with warming and generally quiet weather in the offing for the rest of the week.
