Weekend forecast: Seasonable warmth continues with a mix of clouds and sun

/ October 4, 2024 at 8:50 PM

Quiet weather is expected this weekend as high pressure remains in control. Friday’s occasional showers will be a thing of the past on Saturday as cloud cover gradually thins throughout the day. We start Saturday in the upper 60s, warming to the mid-80s in the afternoon.

More sunshine is in the offing for Sunday as a trough of low pressure aloft moves out and a little bit of ridging moves in. We start the day a touch cooler, generally in the mid-to-upper 60s, warming once again to the mid-80s in the afternoon under partly cloudy skies.

The next front, which arrives with little fanfare on Monday, should finally bring a shot of more fall-like air into the area for next week, with lows possibly dipping into the 50s by next Thursday. Overall, the outlook is for generally quiet and dry weather for at least the next several days.

Friday & the weekend: Quiet, seasonably warm

/ October 3, 2024 at 10:22 PM

Not terribly much to write home about in the weather department this weekend as our weather looks generally quiet with above-normal temperatures expected. A bit more cloud cover works into the area Friday, with a stray shower possible at the coast in the morning. Otherwise, we stay rain-free for the foreseeable future as dry air aloft keeps a lid on shower activity. Temperatures on Friday start in the mid-60s, warming to the low-to-mid-80s in the afternoon.

Saturday runs a little warmer ahead of a weak front that’ll pass by with relatively little fanfare. A mix of sun and clouds is expected throughout the day, but once again, shower activity should be suppressed this far north. We start the day near 70°, warming to the mid-80s in the afternoon, likely a couple clicks higher than we will on Friday.

Post-frontal skies on Sunday will trend a little sunnier, with morning lows in the upper 60s warming to the low 80s in the afternoon. All in all, the next few days look pretty alright weather-wise.

Thursday: Another nice day; clouds increase for the weekend

/ October 2, 2024 at 7:37 PM

Quiet and seasonably warm weather continues for Thursday. We’ll start the day in the mid-to-upper 60s, warming to the mid-80s in the afternoon under partly cloudy skies. Dewpoints will run in the upper 60s, so it’ll still feel a touch humid, but it won’t be too bad overall. The only weather-related issue we could run into tomorrow would be a little bit of salt water on the roads around the 9:01am high tide. Water levels should peak around 7′, which is right where we generally start to see coastal flooding occur. Widespread impacts aren’t expected, but the usual trouble spots may once again be troublesome, particularly around Hagood and Fishburne.

Rest of the work week: High pressure takes over

/ October 1, 2024 at 8:08 PM

High pressure will be in control of our weather for the rest of the week both at the surface and aloft, bringing in quiet and seasonably warm conditions with a fair bit of sunshine, especially on Wednesday and Thursday. Temperatures each day start in the upper 60s, warming to the mid-80s each afternoon.

Rain chances will run essentially nil until late next weekend as a series of fronts move on by. These fronts should keep an area of low pressure in the Gulf of Mexico well to our south. While it may sling some moisture our way, any outsized impacts are not expected, and we actually have another round of slightly cooler and quieter weather expected by the middle of next week.

Tuesday: Mostly cloudy but still warm

/ September 30, 2024 at 10:05 PM

We’ll get October off to a warm but somewhat cloudy start before a cold front starts to regulate temperatures a bit more beginning Wednesday. We start the day rather mild for this time of year once again, with low 70s generally across the metro (and warmer toward the coast). Cloud cover does persist, but despite that, we’ll still warm into the upper 80s. Rain is not expected.

The week ahead: Warm start, but a cooling trend ensues

/ September 29, 2024 at 11:04 PM

There’s not too terribly much to write home about in this week’s forecast so far, which is a fine departure from this point last week when we were looking at the genesis of what would become Hurricane Helene. We close September on a warm note, but a cooling trend begins to kick in by mid-week, with a few showers and thunderstorms — and much cooler conditions — possible by the weekend.

Weekend forecast: Warm, muggy, but sunny post-Helene

/ September 27, 2024 at 10:36 PM

Quieter weather is in store for this weekend (though one could argue the bar is very low for that) in the wake of Helene. It’ll stay warm and muggy, though, as we head down the home stretch of September.

Saturday starts in the upper 60s to around 70°, warming to the mid-80s in the afternoon as a brief shot of cooler and drier air gets us off to a relatively cooler start. It’ll still feel closer to 90°, though, when factoring in dewpoints around 70-71°. The airmass modifies quickly, though, and by Sunday, we’ve got a late summer-ish day with lows in the low 70s warming to the upper 80s that’ll feel more like the mid-90s in the afternoon.

We have a few more days of the muggy airmass before another front sweeps through for the middle of next week, cooling us off pretty nicely as we head through the first week of October.

Rest of today: Clouds and winds diminishing

/ at 12:22 PM

Improving weather is expected this afternoon into this evening as Helene continues to pull away from the area. Winds remain rather gusty — as of noon, a 48 MPH wind gust was reported at the airport — but will diminish as the afternoon wears on. It’ll stay warm and humid, with highs topping out in the low 80s as sun begins to peek through the cloud canopy. We’ll cool to around 70° overnight on our way back to the mid-to-upper 80s on Saturday.

Some housekeeping: The Flash Flood Warning that was in effect for the Charleston metro area, including downtown, has expired. The Tropical Storm Warning remains, but I expect that to be dropped by the 5PM advisory. And yes, the tornado threat has ended.

More on the weekend with this evening’s forecast post as the routine gets back to regular order. Thank you all again for your trust — it’s an honor to help guide y’all through these haranguing meteorological situations!

Helene update: Category 4 storm makes its approach to Florida

/ September 26, 2024 at 6:52 PM

Category 4 Hurricane Helene continues to push toward a landfall in Florida this evening, intensifying rapidly as it does so. Here at home in the Lowcountry, we have been dealing with a fair bit of rain for much of the day, though the severe weather to this point has avoided the Tri-County. That may run out soon, though, as more rain bands develop and move ashore as we get into tonight and the overnight hours.

Helene in the Lowcountry: Tornado Watch issued

/ at 8:59 AM

A potentially busy weather day awaits as Hurricane Helene strengthens again on approach to landfall late tonight on the Big Bend of Florida. A Tornado Watch is now in effect until at least 9PM, though I expect this to be extended overnight, as conditions continue to improve for the development of tornadoes. There has already been one tornado warning this morning in Beaufort County, likely with more to come. Tornadoes are the main concern with Helene, though heavy rain and gusty winds could still cause flooding and power outage issues.
