Now that Bluesky’s added per-account notifications, you can now get your weather information pushed to you on demand whenever I post. One less reason to hang around over *there!*
The high of 82° today missed the record high by one degree — 83°, set in 1942.
November 19, 2025 at 10:45 PM
Sharply warmer temperatures are expected starting Wednesday as high pressure ridges in aloft. Expect highs in the upper 70s to low 80s, especially the further south you are.
Rest of the work week: Temperatures head well above normal
The main weather story for the rest of the work week will be unseasonable warmth courtesy of a ridge building in aloft. Temperatures will run well above normal, with highs approaching 80° particularly Wednesday and Friday (and maybe Thursday, depending on the position of a cold front to the north).

Temperatures will run slightly warmer on Tuesday, though still within striking distance of normal. This changes starting Wednesday, as high pressure at the surface and aloft drives highs near 80°, especially Thursday and Friday.
Tuesday: One more day of seasonable temperatures before warmth returns
After a near-normal day of temperatures on Monday, we'll look for a similar performance on Tuesday. Temperatures will start in the mid-40s across much of the area (a little warmer near the coast, a little cooler further inland), and highs will peak around 70° in the afternoon with mostly sunny skies remaining the rule. Winds will be going more southerly during the day as surface high pressure begins to shift offshore.

After a cold front brings a brief cooldown to the area on Monday, temperatures return to the 70s on Tuesday before heading well above normal for the balance of the week ahead with little rain in sight.

After a brief cooldown on Friday, temperatures head back above normal for the weekend as high pressure remains the dominant weather feature across the area.
Weekend forecast: Warm and quiet weather continues
After a brief cooldown on Friday, temperatures head back above normal for the weekend as high pressure remains the dominant weather feature across the area. We'll see the high that's overhead as of Friday evening slip southward, sending wind directions a little more westerly to southwesterly, kicking temperatures back into the low-to-mid-70s on Saturday. Compressional heating ahead of an advancing cold front will send highs on Sunday solidly into the mid-70s after a warmer start in the mid-50s.

Quiet weather continues for Friday and the weekend as reinforcing high pressure arrives overnight into tomorrow.
Friday & the weekend: Quiet weather continues
Quiet weather continues for Friday and the weekend as reinforcing high pressure arrives overnight. Friday will feel a touch cooler than Thursday did, with winds going back around to the north in the wake of a dry cold front. Lows Friday bottom out in the mid-40s, with highs peaking in the upper 60s in the afternoon under uninterrupted sunshine.

After a record cold day for many of us on Tuesday, a warming trend begins Wednesday and continues into the weekend with plenty of sunshine throughout.
Rest of the work week: Warming trend commences after record lows Tuesday
Record lows were tied both at North Charleston as well as Downtown Charleston Tuesday morning as a potent shot of Arctic air swung through the area. The low at the airport fell to 29°, tying the record first set in 1943, while Downtown fell to 32°, tying the record low first set in 1913. A record cold high temperature appears to have been set as well at the airport, with the high only reaching 49° for the day, breaking the record of 54° set in 1968.

If you have a clear view of the northern sky on the horizon, you may be able to get a look at some aurora courtesy of a strong geomagnetic storm in progress. It'll be easier to see in a darker place.
November 12, 2025 at 2:37 AM
Record lows along with record cold high temperatures are likely Tuesday as abnormally cold air for November spills into the area, bringing about the end of the growing season. Temperatures recover quickly starting Wednesday, and we're back to the 70s by Friday.
Tuesday: First freeze arrives with record lows possible
A highly anomalous Arctic intrusion is arriving this evening, evidenced by gusty winds 25-30 MPH and plummeting dewpoints across much of the area as of 7PM Monday. Further north, some flurries were reported in the Charlotte metro area and as far south as Hartsville, SC. Here at home, the first freeze of the season will occur for the vast majority of us; ensure pets and plants are protected and safe tonight as temperatures will fall into the 20s.

A 40 MPH wind gust was reported with the 7:56 PM observation at Charleston Int’l Airport.
November 11, 2025 at 1:07 AM
Bring in or cover sensitive plants tonight and ensure pets have a warm place to be. The season’s first freeze looks incredibly likely tonight as Arctic air spills into the area. This freeze may get close to the coast, and will almost certainly end the growing season.
November 11, 2025 at 12:54 AM
Showers and storms continue to press eastward toward the coast, and are producing a bit more lightning as they do so. Brief heavy downpours possible as this line moves on by over the next hour.
November 10, 2025 at 3:07 AM
A strong cold front will bring about the first freeze of the season overnight Monday into Tuesday as a highly anomalous intrusion of Arctic air pushes southward. The winter preview will be short-lived, thankfully, with 70s returning for the weekend.
The week ahead: A short-lived shot of winter brings about the first freeze of the season

Showers and a few thunderstorms precede a strong cold front that will sweep through later tonight, ushering in an Arctic intrusion that brings about our first freeze Monday night/Tuesday morning.
November 10, 2025 at 2:16 AM
Showers and a few thunderstorms are moving into the area from the southwest. Be ready for brief periods of heavy rain through this evening.
November 8, 2025 at 6:42 PM
The weekend will stay well on the warm side of normal, but big changes arrive Monday as a strong front ushers in the coldest air of the season thus far, with the first freeze of the season likely Monday night into Tuesday.
Weekend forecast: Spring-like warmth before a wintry chill
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.

Another sunny and seasonable day lays in wait for Tuesday as high pressure remains in control. We'll turn warmer Wednesday through Friday, with the risk for coastal flooding each morning as the full moon arrives.
Tuesday: Another sunny and seasonable day
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.

A quiet and increasingly warm first full week of November lies ahead, though we'll need to watch for some tidal flooding each morning beginning Tuesday.
The week ahead: Generally quiet and turning warmer; coastal flooding an issue, though
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.

November gets off to a sunny start on Saturday with highs in the upper 60s expected. Rain chances start to factor back in for Sunday as we head into the afternoon and evening.
Weekend forecast: Sunny Saturday, a few showers later Sunday
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.

Halloween may be full of frights, but the weather won't be one of them — seasonable and quiet weather is in store through Sunday with high pressure in control.
Friday & the weekend: Plenty of sun with cooler-than-normal temperatures
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.

A cold front will swing through overnight, scouring out the clouds and ushering in drier high pressure behind it, which means the sun returns for Thursday at long last! We'll keep the nice and cooler-than-normal weather going into Halloween weekend, too.
Thursday: Sunshine returns and sticks around
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.
