Seasonably cool for the weekend, with Sunday showers

/ December 18, 2020 at 9:50 PM

If you want to get outside a bit this weekend and enjoy some legitimate sweater weather, Saturday is the day to do it — we’ll have a mix of sun and clouds with highs topping out in the mid-50s. Rain should hold off until after midnight, with periods of showers in the cards for Sunday. It’ll be a touch warmer despite the rain, but temperatures will continue to run below normal through the last shopping weekend before Christmas.

Coastal storm to bring tidal flooding, rain for Wednesday

/ December 15, 2020 at 9:21 PM

This evening, a coastal low is beginning to develop off the Georgia coast. This low will move northward tonight into tomorrow, eventually turning into quite the nor’easter for New England. Locally, expect periods of showers to continue tonight into Wednesday as the low lifts northward and a cold front approaches from the west. Temperatures will remain chilly, only topping out in the low 50s in the afternoon. The front will clear the area during the evening, giving way to drier air for Thursday.

Cooler for Tuesday, with showers returning to the picture in the afternoon

/ December 14, 2020 at 10:03 PM

Clouds will increase overnight into Tuesday morning, giving the day a mostly cloudy look with just a few peeks of sun possible in the morning and early afternoon hours. It’ll feel noticeably colder in the wake of today’s cold front — highs should only top out in the mid-50s.

As low pressure organizes off the coast and begins to move northward, some overrunning should take place, generating scattered light showers across the area by mid-afternoon. Showers will continue into the evening, with the best rain chances arriving with the cold front Wednesday.

The week ahead: Cooling back off with a couple shots of rain

/ December 13, 2020 at 10:33 PM

After what ended up being a fairly nice weekend, we have one more day in the 70s before we’re back to more seasonable — if not a bit below-normal — temperatures across the Lowcountry for the last full week before Christmas. (Yes, it’s almost Christmas. It’s shocking to me, too.)

A cold front will swing through Monday, bringing a chance of showers to the area generally from mid-morning to early afternoon. High pressure will wedge in behind it, cooling us off but also keeping some cloud cover around for Tuesday. Another storm system will ride up the coast Wednesday, potentially turning into a decent nor’easter for the Mid-Atlantic states and New England. We’ll see mostly sunny skies with continued chilly temperatures to close out the work week. Clouds increase for the weekend, with perhaps some showers on Sunday.

Friday and the weekend: Warm, with slight shower chances Sunday

/ December 10, 2020 at 9:44 PM

We’ve got a warmer-than-normal weekend ahead of us as high pressure slips offshore and a cold front approaches from the west.

Friday will remain mostly sunny after some patches of possibly dense fog in the morning. Highs will top out right around 70°, making for a nice afternoon across the area. Similar temperatures are expected Saturday despite more cloud cover. A slight shower chance comes into the forecast late Saturday, continuing into Sunday. Temperatures will top out in the low 70s on Sunday ahead of the cold front.

No washout is expected this weekend — just keep rain gear handy in case a shower comes through. The majority of the rain associated with the front will come through Monday, with the heaviest rains looking to remain to our north.

A really nice day shaping up for Thursday

/ December 9, 2020 at 9:35 PM

Mostly sunny skies and warmer temperatures will make for a very nice Thursday across the Lowcountry. Expect temperatures to start out in the upper 30s to low 40s in the morning, followed by highs topping out in the mid-60s — just a touch above normal for December 10.

A chill in the air for Tuesday

/ December 7, 2020 at 10:01 PM

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.

The week ahead: Another round of cold weather for mid-week

/ December 6, 2020 at 9:50 PM

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.

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

/ December 3, 2020 at 9:55 PM

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.
