Another round of fog is expected overnight into Friday morning as abnormally warm temperatures continue across the Lowcountry. Lows will fall into the mid-50s, reaching the dewpoint with relatively calm winds. Once again, be prepared for low visibility and delays due to fog as you commute Friday morning. Like Thursday, the fog should mix out by mid-morning, and from there, temperatures will head to the mid-to-upper 70s. We’ll challenge the record high of 78° set in 2012 with a mix of sun and clouds in the afternoon.

We may get another abnormally warm January day off to a foggy start across a good bit of the area as winds go calm and temperatures fall to right around their dewpoints in the low-to-mid-50s. It’s not a slam dunk that we’ll run into fog, but better to be ready for it and the associated commute delays that may come along with it.

If it develops, fog should eventually mix out by mid-morning as temperatures head into the low 70s once again under generally partly cloudy skies. It’ll be a much warmer-than-normal day — a normal January 8 should only see highs peaking around 60° — but at least the record of 81° set in 2005 will remain unchallenged.

I hope you and yours are having a nice and safe start to your 2026! We certainly have had a nice day of weather on Thursday to kick the new year off right, but the first storm system of the year won’t waste any time getting through the area on Saturday.

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.

I hope everyone celebrating had a very Merry Christmas! It was certainly a warm one as the high reached 78° today, just two degrees off the record of 80° last set in 2015 and cementing itself ahead of Christmas 2016 for the second-warmest Christmas high temperature on record at the airport.

A backdoor cold front stalling nearby will drive more cloud cover into the area for Friday as well as a bit more in the way of onshore flow, which will make for a cooler day (though temperatures will remain above normal). Lows in the low-to-mid-50s will warm to the upper 60s to around 70°. Model guidance keeps the core of the cold air damming regime to the north of the area, but some spots further north in the Tri-County could see temperatures come in a little cooler than that depending on how far south the front penetrates.

A front will sweep away the dreary and damp Thursday, yielding a much nicer Friday with much more sunshine. We’ll start the day in the mid-50s with some cloud cover still hanging around, but that should depart by midday. Temperatures will warm to the mid-to-upper 60s with breezy westerly winds, which will be gusty early in the day, peaking in the 20-25 MPH range. Winds will gradually slacken some as the day goes on, though.

A brief warmup is in the cards for Friday and again on Saturday before a front moves by with some showers Sunday. This front will usher in a bitterly cold Arctic airmass that’ll plunge temperatures into the low 20s by Monday morning.

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.

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! We’ll have plenty of sunshine, though, with no weather worries for the holiday.

After a slightly cooler and more cloudy day courtesy of a backdoor cold front, temperatures will head back into the upper 70s on Friday as the aforementioned front washes out with high pressure moving offshore. We start the day in the mid-50s and perhaps with some fog. Cloud cover will gradually diminish as the day goes on, and we should have a pleasant close to the day as we head into the weekend.
