The week ahead: A few more warm days, then cooling back off for Thanksgiving

/ November 23, 2025 at 10:29 PM

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.

Monday starts out in the upper 40s to around 50° given clear skies and generally light winds, which could lend itself to some fog formation early. Surface high pressure will situate itself to our north during the day as a ridge of high pressure aloft nudges in from the south and west, and this will allow temperatures to top out generally in the low 70s in the afternoon with plenty of sunshine.

The pattern remains fairly progressive, though, and by Tuesday morning high pressure is sliding offshore with a few showers potentially coming in off the ocean as a warm front lifts north across the area. (Most of us look dry, though.) A bit more cloud cover will be the main governor on high temperatures as winds at the surface go more southerly, but we’ll still see highs peak in the mid-70s after a start in the mid-50s. A strong piece of mid-level energy will drive a cold front toward the area on Wednesday. The warmest weather of the week occurs ahead of this front, with lows around 60° and highs in the mid-to-upper 70s in the afternoon. A few showers could accompany the frontal passage, but moisture is otherwise fairly scarce once again, so don’t expect much in the way of rain (if any at all).

The front gets through overnight Wednesday into early Thursday, bringing about cooler and drier air as strong high pressure builds in from the west. Thanksgiving Day starts around the mid-40s, but only warms to the low 60s in the afternoon with increasing sunshine. Black Friday runs even cooler, with a rather chilly start in the mid-30s (perhaps reaching freezing further inland) warming to only the mid-to-upper 50s despite plenty of sunshine. A warming trend commences over the weekend, but temperatures will stick around on the cool side of normal overall. A shower or two might not be out of the question for Sunday as a coastal trough could develop, but there’s plenty of time to keep an eye on that.
