We’ll finish 2024 on a rather warm note before a cold front ushers in the first of what should be several rounds of cold air to start 2025.

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.

Sunday looks to be an active weather day as a cold front approaches the area. Expect at least scattered to numerous showers and thunderstorms to develop throughout the day, with a possible squall line moving by sometime in the early to mid-afternoon hours.

The final weekend of 2024 will be unseasonably warm as we get into the warm sector of an approaching storm system that could bring some rough conditions on Sunday.

A coastal trough continues to affect the area today, with showers overrunning the top of a cold high pressure wedge that has kept temperatures pretty constantly in the mid-40s for the past couple days now. We should see that trough lift inland later today, though, as high pressure anchored to the northeast weakens and steps aside. This will help break the wedge and allow a little warmer air to move in, especially later, though we will stay somewhat cool with highs in the upper 50s. The risk for showers should also diminish with time today, though we can expect off and on rain for much of it.

We get Christmas Eve off to a chilly and wet start on Tuesday, but showers will diminish throughout the day as low pressure pulls away from the area. Temperatures bottom out in the upper 30s to around 40°, with wind chills making it feel even cooler. As the day goes on, temperatures will head into the low to mid-50s in the afternoon with some breaks in the clouds developing.

Christmas morning will start out seasonably cool, with lows once again topping out in the upper 30s to around 40°. It’ll be a bit warmer of a day with more sunshine expected; highs should peak around 60° in the afternoon. Northeasterly winds will be a touch on the breezy side, but otherwise, no concerns for Christmas Day.

I hope you have a happy and safe holiday!

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.

Temperatures will tumble once again as we head into the weekend as a couple shots of cooler and drier air work their way in. Friday will feature decreasing cloud cover throughout the day as the first round of drier air continues to filter in; expect lows in the upper 40s to around 50° to warm to the mid-60s in the afternoon.

A second, more potent, shot of Arctic air works into the area overnight Friday. We’ll feel it Saturday morning as lows head down into the upper 30s. Ongoing cool advection will keep highs in the low to mid-50s despite plenty of sunshine.

Sunday morning dips below freezing for the first time in a few days, with lows in the upper 20s to around 30° expected away from the coast. Highs will once again struggle and may not make it out of the 40s with more sunshine expected.

A front will pass through overnight Wednesday into Thursday, but we’ll keep cloud cover around and maybe even a shower or two as a trough of low pressure hangs around for one more day. Temperatures will start in the mid-to-upper 50s once again, but we’ll warm to just the mid-60s with the cloud cover and a somewhat cooler and drier airmass working its way in.

A cold front will swing through on Wednesday to put a bit of a governor on the recent unseasonable warmth, but thereafter, expect a much sharper cooldown into the weekend.
