The cold front that brought some much-needed rainfall to the area on Saturday will clear the area for Sunday, bringing about a cooler, drier, and sunnier day after some patches of fog in the morning. Temperatures start around 40°, but northerly winds blowing in cooler air will keep temperatures capped below 60° for most of us. Sunday will be the coolest day of the week as high pressure shifts offshore, bringing about quite a warm spell for the first full work week of 2026.

We’ll get 2026 off to a slightly chilly but seasonable start with surface high pressure in control. Temperatures will fall to the mid-30s by morning, with some freezing temperatures possible closer to I-95. With plenty of sunshine, though, temperatures will rebound right to where they should be for the beginning of the year, with highs peaking around 60° in the afternoon. It’ll be a bit breezy, especially in the morning, but those winds will slacken some as we head into the evening.

A cold front getting through the area Monday afternoon will usher in much cooler air for Tuesday. We’ll start the day around freezing away from the coast, with wind chills bottoming out in the mid-to-upper 20s in the morning thanks to northwesterly winds around 5-10 MPH. This breeze continues for much of the day. Despite full sunshine, the ongoing influx of cold air will keep highs pinned to the low 50s across the metro.

While it won’t be as windy as it was on Monday morning, we still have quite a frigid start queued up for Tuesday as lows drop back to the low 20s in the morning, with some upper teens possible closer to and west of I-95. However, with high pressure beginning to slip to the east, we’ll start to see temperatures begin to moderate in the afternoon as mostly sunny skies prevail. While the forecast high of 54° remains well below normal for this point in December, it will feel tropical in comparison to Monday’s high of 39° at the airport (which ties the record cold high temperature first set in 1942).

Another dry front will come through overnight with a reinforcing shot of cooler air for our neck of the woods, but at least we won’t be starting the day with freezing fog like we did this morning. Freezing fog occurs when fog develops at temperatures below freezing, producing a glaze of ice on surfaces it comes into contact with (generally elevated surfaces). This morning, temperatures fell to the dewpoint of 28°, which aided in its formation and caused quite a few problems on bridges and overpasses, with numerous traffic accidents and closure of both the Don Holt and North Bridges. Freezing fog is incredibly, incredibly rare for this part of the world — in fact, this morning’s Freezing Fog Advisory was the first ever issued for the Charleston metro area, and only the second issued by NWS Charleston, SC (the first one was issued in 2022).

Thankfully, we will not deal with this Thursday morning as temperatures are expected to stay above freezing, generally running in the upper 30s to around 40°. The aforementioned dry front comes through early in the day, and this helps usher in another shot of cooler air that’ll keep things breezy and chilly Thursday afternoon, with highs only reaching the low 50s despite partly cloudy to mostly sunny skies. Morning wind chills may bottom out in the low 30s, so layer appropriately.

We’ll finally shed the cloud cover that’s punctuated the last several days on Tuesday as high pressure builds in from the northwest. The aforementioned high pressure will drive even cooler and drier air into the area, and we’ll wake up below freezing as a result away from the coast. The northerly breeze will help drive wind chills down into the low to mid-20s during the morning, so be sure to add a layer or two as you head out for the day. The feed of cooler and drier air continues throughout the day, so even with plenty of sunshine, highs will likely not climb out of the upper 40s.

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. Temperatures will remain on the cool side, with lows in the low 40s warming to just the mid-50s in the afternoon at best, making for a sixth consecutive day of highs in the 50s.

This dreary stretch will start to work itself out on Monday, with a front ushering in cool and dry high pressure by Tuesday, which will scour out the clouds. It’ll be chilly still, but we do have a brief warmup into the low 60s for Wednesday and Thursday before cooling right back off for the weekend with another front.

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. It’ll be a mild day once again, with lows in the mid-50s warming to the mid-70s in the afternoon in the wake of the warm front.

Warm temperatures continue for Thursday, though a nearby front and some more cloud cover will likely preclude temperatures from getting too out of hand. Wednesday’s highs were close to records for the date: 82° at the airport was just a degree shy of the record of 83° set in 1942, while 80° downtown missed the record of 82° set there in 1958. Depending on where the front hangs up, we may yet make another run at records, but the preponderance of the evidence suggests that we’re going to stay in the mid-to-upper 70s on Thursday. The front won’t come with much moisture, so an uptick in cloud cover is about it.

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. This will set us up for a few days of rather warm temperatures starting Wednesday.
