Thursday: Front comes through with very cold air to follow

/ January 14, 2026 at 6:18 PM

A cold front will come through early Thursday, ushering in another round of very cold and dry air to the area which may elevate fire danger during the day. We’ll start the day in the mid-to-upper 30s with a few clouds around. Those clouds will largely scour out as the drier air punches in, and it will punch in — expect winds around 10-15 MPH with higher gusts at times. The influx of cold air will limit highs to the upper 40s despite full sunshine, and with the wind, it’ll feel even cooler than that. This will lead to a hard freeze overnight Thursday into Friday morning, so you’ll want to make sure that pets, plants, pipes, and people are protected as temperatures plummet into the low 20s by Friday morning.

Rest of the work week: A few showers possible Wednesday, then turning colder

/ January 13, 2026 at 6:10 PM

Another big cooldown is in store as we get beyond Hump Day and head into the second half of the work week. First, though, we’ll have a relatively seasonally-appropriate Wednesday, with highs topping out in the upper 50s to around 60° after a low around 40°. There will be a bit more in the way of cloud cover, with a chance for a few showers in the afternoon as low pressure moves northward out of the Bahamas, spreading a little moisture our way. Don’t expect much in the way of any meaningful rainfall, though, if you see any at all.

Tuesday: Another chilly start, but a bit warmer in the afternoon

/ January 12, 2026 at 7:22 PM

We’ll get off to another rather chilly start on Tuesday, with sheltered and rural locations headed below freezing and the metro getting awfully close (if not tipping below 32°F, too). At least the wind won’t be a factor — maybe a very light breeze, but that’s about it. Temperatures will then warm to around 60° in the afternoon, which if realized would be right on the nose for what climatology considers “normal” for January 13. Expect plenty of sunshine with just a few clouds.

The week ahead: Feeling much more like January

/ January 11, 2026 at 10:14 PM

This week will have a much different (and more seasonally-appropriate) feel than last week did as multiple shots of cold air are queued up for our neck of the woods.

Weekend forecast: One more warm day before a front cools things off

/ January 9, 2026 at 7:19 PM

After a record high on Friday, we’ve got one more warm day ahead before a cold front begins to make things feel a little more like January for Sunday and especially the start of the new work week.

Friday & the weekend: Morning fog returns as temperatures peak ahead of a front

/ January 8, 2026 at 7:26 PM

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.

Thursday: Another warm day with dense fog possible in the morning

/ January 7, 2026 at 8:14 PM

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.

Rest of the work week: Another uptick in warmth

/ January 6, 2026 at 9:51 PM

Warmer-than-normal temperatures will continue for the rest of the work week, with a stretch of 70° days expected beginning Wednesday. Lows Wednesday bottom out in the mid-50s — typical early January lows are closer to the upper 30s — while warming to the low-to-mid-70s under partly cloudy skies.

A few more clouds work their way in for Thursday and Friday as high pressure traverses to our north and a storm system to the west chucks some cirrus our way. We’ll cool down a touch for Thursday, but we will still remain well above normal as high pressure starts to ridge overhead. By Friday, surface high pressure is back offshore, and warmer air pumps right back in, sending temperatures to the mid and perhaps upper 70s, which may challenge record highs.

The next cold front approaches Saturday, which will be one more near-record-warm day before the front sends temperatures plunging below normal for Sunday into early next week.

Tuesday: Warmer than normal conditions continue, with another upswing later this week

/ January 5, 2026 at 9:16 PM

Our run of above-normal temperatures is just beginning, and will continue through Tuesday and the rest of the work week. Expect lows to bottom out in the upper 40s to around 50° on Tuesday morning, with temperatures warming into the upper 60s to low 70s in the afternoon under a mix of sun and clouds.

Warmer-than-normal temperatures kick off the first full work week of 2026

/ January 4, 2026 at 3:21 PM

A quiet and warm week of weather lies ahead as we go back to work and school for the first time in 2026. Temperatures this week will climb some 10-15° above normal at times, but we should stay just short of any record highs.
