A mostly quiet week of weather lies ahead across the Tri-County area with high pressure aloft contributing to some of the warmest weather thus far in 2025.
January will end much differently than how it has gone thus far as temperatures head around and even above normal to close out the month and bring in February with just a few rain chances mixed in to start and end the week.
A chilly week ahead is bookended by two winter storm systems that will affect the area. Whether wintry precipitation gets involved remains to be seen; the probability of anything but cold rain taking place in the Charleston metro remains very low.
After a windy and wet cold front on Sunday that, thankfully, was devoid of any severe weather in the Lowcountry, we’ll finish 2024 on a warm but quiet note and ring in 2025 with more seasonable temperatures.
We start the holiday week off on a chilly note. Expect subfreezing temperatures inland of the coast Monday morning, with wind chills in the low 20s expected. We could even see those wind chills drop below 20° further inland, prompting a Cold Weather Advisory for inland Berkeley and Dorchester counties from 4-9am. Cloud cover will build across the area throughout the day Monday, with even a stray shower possible at the coast. Highs will remain well below normal, with low 50s expected at best.
The week ahead will feature another up-and-down cycle of the temperature rollercoaster that has characterized this climatological winter so far. We start the week on the warm side, with temperatures running well above-normal through Wednesday. Monday could start a bit foggy as lows only drop to about 50°. We’ll warm to the low 70s in the afternoon under partly cloudy skies. After what could be another foggy start, expect a little reduction in cloud cover Tuesday afternoon which will lead to what should be the warmest day of the week as highs peak in the mid-70s (and maybe even a bit warmer further inland).
We get off to a warm start this week as temperatures return to the 70s for a few days (albeit with showers, especially Tuesday into Wednesday), followed by another cooldown that sends temperatures back below normal for the second half of the week, though not to the extent we saw last week.
Seemingly on cue for climatological winter, temperatures will remain below normal pretty much all week, with a couple reinforcing shots of cool air to keep us honest interspersed throughout. We stay mostly rain-free, with the possible exception of later Saturday night into Sunday as another front with a few showers looks to move by.
The week ahead will look a bit like last week: starting warm, a mid-week front, and a chilly round of weather for Friday and the weekend (that, in fact, will run even cooler than we did these past few days).
First, though, we’re back in the 70s on Monday as high pressure at the surface starts to move offshore. This makes for a seasonably warm day, starting in the mid-40s and warming to the low 70s in the afternoon. We turn warmer on Tuesday ahead of what should be a dry, fairly weak front, with a start in the mid-50s yielding to highs in the mid-70s in the afternoon under mostly cloudy skies. The front only acts to knock temperatures down a couple degrees, so Wednesday remains warmer than normal with lows in the low 50s yielding to highs in the low 70s in the afternoon.
Thanksgiving Day will be mostly dry, though a stronger front approaching from the west will bring rain chances into the area in the evening through the overnight. It’ll be a warm day, with lows in the mid-to-upper 50s warming to the mid-70s in the afternoon ahead of the rain. Once this front gets through, though, we’ll feel a noticeable change as another shot of cool air moves in. Black Friday’s highs should only peak in the low 60s — some 15° cooler than Thanksgiving — as rain and clouds depart. We’ll stay quite cool heading into the weekend, with perhaps some frost concerns each night as lows on Saturday and Sunday bottom out in the mid-30s, while highs only peak around the mid-50s each day.
