A seasonably cool weekend awaits

/ December 4, 2020 at 9:44 PM

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.

Rain on Friday, then another reinforcement of cool air for the weekend

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.

After another freeze, warming begins on Thursday

/ December 2, 2020 at 9:04 PM

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.

First freeze for Wednesday morning, with wind chills in the low 20s

/ December 1, 2020 at 8:33 PM

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.
