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!*
Another chilly and raw evening, but rain is slowly coming to a pause as a little bit of drier air moves in. More showers tomorrow, though.

Dreary weather continues for Sunday with a few more showers possible. Skies will begin to clear on Monday as drier air punches in, with much more sunshine by Tuesday.
Sunday: Cool and dreary, with a few lingering showers
We've had some much-needed rain over the past few days, but it's certainly not made for the best outdoors weather, either. Unfortunately that continues on Sunday, which will decidedly not live up to its name as overcast skies look to persist with a few showers continuing to be possible at times. It won't be as much rain as we've seen over the past couple days with some drier air working in, but there will still be enough moisture to wring out a few more raindrops.

Much-needed rain and below-normal temperatures are in store for the week ahead as a series of fronts affect the area. We’ll also see the risk for some tidal flooding in the mornings beginning Tuesday.

Front incoming…60s and 70s ahead of it, while the Upstate isn’t getting out of the 40s today!

Well, we made it: Today marks the last day of the 2025 hurricane season.

Cooler air will arrive for Thanksgiving, with highs just peaking around 60° tomorrow. Even colder weather is expected Friday and Saturday, with some frost and freeze concerns, before we warm up ahead of the next storm system on Sunday.
Thanksgiving: Break out the sweaters
One front has come through as of this writing Wednesday evening, with another front hot on its heels to pass through overnight into early Thanksgiving morning. This second front is going to bring in quite the cooldown for the next few days, especially as we get into Friday and Saturday, but Thanksgiving will certainly illustrate the contrast from the past few days: expect lows in the mid-40s to warm to just about 60° in the afternoon, which is just a hair warmer than Wednesday's morning low!

A cold front will come through on Wednesday, bringing a few showers during the day before temperatures get taken down a few pegs just in time for Thanksgiving.
Rest of the week: Turning much cooler
A cold front will come through Wednesday, knocking temperatures down for Thanksgiving and Black Friday.

Showers are approaching from the south and should impact at least some of us, especially closer to the coast, over the next few hours. Nothing too out of bounds here but a brief downpour is possible. Watch for slick roads.
November 25, 2025 at 2:10 PM
High pressure will depart on Tuesday, allowing a warm front to move northward and bring more warm and humid air with a chance of a few showers. A Wednesday evening front brings us much more seasonally-appropriate weather just in time for Thanksgiving, though.
Tuesday: More clouds, maybe a shower
High pressure to our north will be shifting offshore as Tuesday goes on ahead of a storm system moving through the Ohio Valley, allowing a warm front to push northward into the area during the day. Some of us may see a few showers as this warm front moves northward, especially later in the morning and closer to the coast. They'll be relatively short-lived, clearing the area during the afternoon, and won't amount to too terribly much rain for those who see any of it at all.

We'll start Thanksgiving week out on an unseasonably warm note, but a temperature correction is incoming starting Thanksgiving Day as a strong cold front moves by. We'll have a couple more slight rain chances, but overall, we'll be largely dry.
The week ahead: A few more warm days, then cooling back off for Thanksgiving
We'll start Thanksgiving week out on an unseasonably warm note, but a temperature correction is incoming starting Thanksgiving Day as a strong cold front moves by. We'll have a couple more slight rain chances, but overall, we'll be largely dry as drought conditions continue to creep further into the Lowcountry.
