New Year’s weekend: Soggy Saturday, drying out Sunday

/ December 30, 2022 at 5:45 PM

2022 will come to an unsettled end across the Lowcountry as showers and perhaps a few thunderstorms develop and move through ahead of a cold front. A stronger storm or two will be possible near I-95, but otherwise expect generally off and on showers. The best risk for showers will occur in the afternoon through the early evening hours; yes, it is conceivable we may have the precipitation out of here as the clock strikes midnight. It will certainly be mild, with highs in the low 70s. Temperatures will run in the upper 50s as 2023 begins, so it should be fairly comfy with a light jacket.

The atmosphere will be drying out during the day Sunday, with cloud cover decreasing and some drier air moving in. It’ll still be warm, though, thanks to high pressure ridging aloft: once again, expect highs in the low to mid-70s. Overall, not a bad start to 2023!

Back to the 60s for Thursday, with warm weather continuing into 2023

/ December 28, 2022 at 7:07 PM

After a high of 62° today — the first time since December 17 that we’ve crossed the 60° threshold — we will be back into the 60s tomorrow across the metro, with temperatures running a few degrees warmer than they did today. Most notably, those of us east of Highway 17-A will remain above freezing into tomorrow morning for the first time since December 23. Those of you along and inland of 17-A will want to take freezing weather precautions for just one more night as lows dip below 32° for a time, with a few upper 20s possible in more sheltered locations. However, many of us will not need to drip faucets or take other precautions tonight (though bringing your pets in is always a good idea this time of year).

Rest of the work week: Warming trend continues

/ December 27, 2022 at 8:09 PM

We will continue to trend warmer heading toward New Year’s Weekend. First, though, we’ve got to get through one more night of subfreezing temperatures, and then we get a long break. But once again tonight, though, be sure to have a faucet dripping, pipes insulated, pets indoors, plants covered, and the people in your life accounted for and warm. Temperatures will bottom out in the upper 20s — certainly not as severe of a freeze as we have seen recently — across the metro area. The good news is that we’ll warm nicely with temperatures approaching 60° in the afternoon under brilliantly sunny skies.

Tuesday: One more morning in the 20s as the warming trend continues

/ December 26, 2022 at 8:27 PM

We head back well below freezing overnight into Tuesday morning as gradually modifying Arctic air remains in place across the area and mostly clear skies allow for good radiational cooling. This is going to be another night where you’re going to want to have a faucet or two going to prevent burst pipes or other leaks from developing. Make sure pets are inside, sensitive plants are indoors or covered, and your loved ones and neighbors are warm.

Temperatures should be above freezing by 10am on their way to the low 50s in the afternoon. A shortwave trough will be swinging by in the morning through early afternoon, instigating some cloud cover but little else as very dry air remains in place across the area. We should see some clearing begin to take shape before sunset, after which temperatures will once again quickly fall back into the 30s.

The week ahead: Last week of 2022 turns progressively warmer

/ December 25, 2022 at 8:40 PM

We begin the final week of 2022 with Arctic air continuing to make its presence felt across the area. We’ll start Monday in the upper teens to low 20s, with freezing temperatures all the way to the coast once again. It’ll be another night to make sure that pets, plants, and people are well accounted for, and that pipes are protected with extra insulation and a dripping faucet. Highs will top out again in the low-to-mid-40s under predominantly sunny skies.

Christmas Day forecast: At least we get above freezing

/ December 24, 2022 at 9:26 PM

After record-breaking cold on Christmas Eve, we have another round of cold — but perhaps not quite as cold — weather for Christmas Day.

We begin the day with another Wind Chill Advisory as another round of low teens wind chills is forecast across the area. Air temperatures will drop to around 20°, with another dip into the teens possible further inland as well as in more rural areas. The good news is that after what should amount to about 40 consecutive hours below freezing, we will finally exceed the melting point by early afternoon, which will give us some much-needed thaw time. Skies will be mostly clear throughout the day, and at least some unfiltered sunshine will help it feel not as bitterly cold as it was on Saturday, though wind chills will still, at best, run in the low 30s.

Record cold expected for Christmas Eve; not much warmer Christmas Day

/ December 23, 2022 at 8:23 PM

Christmas weekend has arrived, and so has that unreal shot of Arctic air. Temperatures peaked around 56° at 8:49am just before the front passed by the airport. From there, temperatures have been steadily dropping throughout the day as dewpoints headed into the low single digits, making for a very dry feel to the air.

Christmas weekend: Arctic outbreak arrives

A very potent cold front will be coming through early Friday, bringing strong, gusty winds, dangerous wind chills, and several mornings in a row of pipe-busting cold for the Christmas holiday weekend.

Thursday: Soggy start, with moderate to major tidal flooding possible

/ December 21, 2022 at 7:22 PM

Thursday will bring somewhat complex weather to the Lowcountry with a very soggy start to the day as low pressure moves across the area, followed by a dry slot moving into the area in the afternoon to shut off the rain. Of course, we continue to monitor the progress of an incredibly potent Arctic cold front as it progresses across the country, with it expected to clear our area on Friday.

Rest of the work week: Unsettled conditions continue, then turning much colder Friday

Wet weather will continue on and off through early Friday before an outbreak of Arctic air brings much colder air and strong winds to the area for Christmas weekend.
