Weekend forecast: Spring-like warmth before a wintry chill

/ November 7, 2025 at 10:45 PM

A couple more warm days lie ahead before the coldest airmass of the season crashes into the area next week. Saturday will generally feature temperatures in the upper 70s after starting the day near 60°. We’ll keep a few clouds around, but the risk for any rainfall should be very low.

A strong front approaches the area Sunday, and there’s a chance that some showers and maybe a thunderstorm could move through in advance, but the risk will be diminishing as the front pushes eastward as moisture doesn’t look to be in abundance. Temperatures Sunday peak near 80° after starting in the low 60s.

Tuesday: Another sunny and seasonable day

/ November 3, 2025 at 8:02 PM

Plenty of sunshine will continue on Tuesday as high pressure builds across the area from the west, keeping northeasterly flow in place which will keep temperatures on the cool side of normal and also help to elevate the morning high tide into minor flood stage. We’ll start the day in the mid-40s, warming to the upper 60s in the afternoon, which will feel quite comfortable with the sun out. The aforementioned northeasterly winds will run generally in the 5-10 MPH range, which will be enough of a breeze to make it feel a little cooler in the shade.

As mentioned, some coastal flooding will be possible between 5-8am as water levels peak in minor flood stage (7-7.2′) with the 6:11 am high tide. This may have limited impacts in the most vulnerable areas of the peninsula, primarily around the Hagood/Fishburne intersection as well as possibly on parts of Lockwood. Be ready to reroute around any closures.

The week ahead: Generally quiet and turning warmer; coastal flooding an issue, though

/ November 2, 2025 at 11:41 PM

The week ahead looks generally quiet and increasingly warm, especially as we get into late week and the first part of the weekend, but nothing too out of bounds for early November. Coastal flooding will become an issue beginning Tuesday as favorable winds and the highest astronomical tides of the season coincide, though.

Weekend forecast: Sunny Saturday, a few showers later Sunday

/ October 31, 2025 at 11:11 PM

November will get off to a sunny and somewhat chilly start as lows head into the low 40s for the first time since late March with clear skies and calmer winds letting things cool off a little more than Thursday night. We’ll then warm to the upper 60s in the afternoon with plenty of sunshine to be had as high pressure slides overhead.

Friday & the weekend: Plenty of sun with cooler-than-normal temperatures

/ October 30, 2025 at 7:02 PM

Halloween may be full of frights, but the weather won’t be one of them — seasonable and quiet weather is in store heading into Sunday with high pressure in control. Lows Friday bottom out in the mid-40s in the metro, with perhaps even lower temperatures further inland and in rural areas. We’ll warm to the mid-to-upper 60s in the afternoon with predominantly sunny skies and a gentle breeze out of the west. Saturday is essentially a carbon copy of Friday, though winds will be a little calmer and shifting direction out of the northeast and east. Don’t forget to set your clocks back an hour Saturday night as we fall back to Standard Time.

We’ll start to see dewpoints to climb back up and cloud cover begin to thicken as Sunday goes on in advance of the next storm system advancing out of the Gulf. Rain should hold off for the vast majority of the day, though a shower or two can’t be ruled out in the late evening. Temperatures on Sunday run a little warmer, with lows in the mid-to-upper 40s and highs approaching 70° despite the increasing cloud cover.

Thursday: Sunshine returns and sticks around

/ October 29, 2025 at 7:53 PM

A cold front will swing through overnight, scouring out the clouds and ushering in drier high pressure behind it. It’ll be great to see the sun, which will make highs in the mid-60s feel quite nice. We’ll have a bit of a westerly breeze in the wake of the front, so keep that in mind if you have any plans to dine al fresco, but otherwise, it looks like a really good day of weather across the Lowcountry.

Rest of the work week: One more front, then much more sun

/ October 28, 2025 at 7:29 PM

After the coolest day since late February — the high at the airport only peaked around 57° — we’ll turn warmer on Wednesday as an approaching cold front scours out the wedge of high pressure that brought us a dreary, drizzly Tuesday. We’ll start Hump Day around 50° under mostly cloudy skies once again. A warm front lifting northward will push through the area later in the afternoon, and it’s that warm front along with some breaks in the cloud cover which will help us warm to the mid-to-upper 60s later in the day. Shower chances will return in the evening through the overnight as a band of rain ahead of the cold front moves by.

Showers should depart by the time most of us get Thursday underway. We’ll start in the upper 40s to around 50° once again, warming to the mid-60s in the afternoon with much more in the way of sunshine than we’ve seen so far this week. Clearer skies overnight Thursday will allow Halloween to start a little cooler, generally in the mid-40s in the metro (with lower temperatures possible further inland as well as in some more rural areas). Unfettered sunshine will send temperatures in the mid-to-upper 60s in the afternoon. Trick-or-treaters and their accompanying guardians (where applicable) should expect temperatures to fall into the 50s around and after sunset.
