Jared Smith founded @chswx on Twitter in 2008 as an experiment in disseminating weather data through social media. In the ensuing decade-and-a-half, @chswx has provided live coverage of tropical cyclones, tornadoes, severe weather, and even a couple bouts of winter weather to the good people of Charleston, SC.
After a fun evening of rain mixed with graupel, we return to clear and chilly conditions for Tuesday. Temperatures will fall to freezing in a few spots well inland, with low to mid-30s across much of the Charleston metro. Factor in a decent northwest breeze and it’ll feel closer to the mid-20s in the morning.
We’ll remain under full sunshine throughout the day, but temperatures will struggle to the low 50s as cool air continues to filter into the area.
Another week in December, and another round of freezing temperatures in the cards for mid-week. We’ll start the week with some showers in the area as a cold front gets through the area early Monday, followed by some lingering shower activity as a trough of low pressure hangs around behind the front. Once the low clears the area, temperatures really begin to fall off, and we’re back in the 50s on Tuesday after dipping into the mid-30s, well into “bring pets and plants in” territory. Expect another freeze Wednesday morning away from the immediate coast before temperatures rebound to near 60°. Mostly sunny skies continue Thursday and Friday as temperatures begin to moderate back around normal (mid-60s) for the second week of December. Then, a cold front approaches the area over the weekend, bringing some slight shower chances to the area Saturday and Sunday.
After a few more showers tonight, a cold front will swing through the area, reinforcing the cooler-than-average temperatures that have punctuated December so far (aside from today’s 70s, anyway). Clouds will scour out quickly in the morning on Saturday, yielding mostly sunny skies with highs in the low 60s as high pressure builds in from the west.
Cloudiness will begin to rebuild into the area on Sunday as a storm system gets together in the Gulf and heads toward Florida. We’ll see temperatures remain a few degrees below normal — generally around 60° — after a chilly start in the upper 30s in the metro area (cooler well inland and in more rural locations). Showers should hold off for much of Sunday, with rain chances beginning to come back into the picture after sunset as the low pressure system approaches Florida, and some overrunning precipitation develops on the northern flank.
Friday will see a brief return to the 70s as a cold front approaches the area. Showers look to begin in the afternoon and will continue through the overnight, with the bulk of the rain falling during the late afternoon/evening hours. Rain will taper off overnight as the front moves through, and by sunrise Saturday we should see clearing skies and breezy westerly winds.
The weekend looks nice and sunny, but will be a little chilly. Highs will only get to the low 60s on Saturday in the wake of the front. The cool weather continues on Sunday, with lows in the upper 30s and highs topping out in the upper 50s. This will still run a little below normal for the first weekend of December, but won’t be quite as cold as the airmass we had earlier this week.
Bring in your pets and plants again tonight as temperatures will be headed toward the freezing mark once more, generally along and inland of Highway 17. The freeze won’t be quite as widespread as we saw this morning, but expect temperatures to fall into the 30s close to the coast, including into downtown Charleston.
After the chilly start, temperatures will rebound back into the 60s for the afternoon as winds turn more onshore throughout the day. Expect clouds to increase as well from the west ahead of our next storm system, which brings rain back to the area for Friday.
Bring in plants and pets tonight as temperatures will be dropping into the upper 20s in many spots away from the coast. Temperatures will dip into the 30s even near the coast, with an outside shot at freezing at downtown Charleston.
At least the afternoon will be warmer than today’s 48° — the airmass will slowly modify starting Wednesday, allowing for highs in the mid-50s. We’ll be back in the 60s by Thursday with increasing clouds ahead of our next storm system.
We in the weather community have been talking about this cold snap for a while, and it is finally here. Tuesday promises to be a very chilly day — the coolest since mid-February — with highs struggling to reach 50° despite full sunshine. A persistent westerly wind will keep temperatures feeling even colder, too, with wind chills in the upper 20s expected in the morning. Make sure your loved ones, two and four-legged, have a warm place to be tonight (and for the next couple nights).
We’ll get this week off to a rainy and windy start as the storm system which rained on us for a fair bit of today moves through the area on Monday, ushering in the coldest air of the season in its wake.
Sunday will start out dry and mostly cloudy, but will turn more rainy as a warm front lifts north across the area during the afternoon and evening. This rainfall is associated with a storm system that will move across the Gulf Coast states tomorrow and then more northeastward into the Mid-Atlantic Sunday night into Monday, ushering in a legit winter chill behind it — just in time to start meteorological winter on Tuesday.
While it’d be unfair to characterize the weekend as a washout, we do face periods of unsettled weather as a frontal boundary remains stalled to our south in Georgia and a potent storm system approaches the area from the west.
Saturday morning, expect light rain to move across the area as a wave of low pressure along the stalled front moves from west to east with a little upper-level support to boot. It’s not likely that we’ll see much more than a tenth or two of an inch of rain across the Lowcountry from this round of rain, and it should conclude by early afternoon. We should get at least a few peeks of sun before Saturday’s all said and done, and the evening will remain dry. Temperatures will run a little cooler than previous days, only topping out in the upper 60s.
