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.
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.
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.
Tomorrow’s forecast, personally speaking, gives me the ick. High pressure wedging southward and moisture running atop of it thanks to low pressure to our south will help generate a chilly, cloudy, and at times rainy day in the Lowcountry tomorrow. We are already starting to see cloud cover thicken tonight primarily in the mid- and upper levels as of this writing with rain encroaching into southeast Georgia. Expect showers to build as the day goes on, with maybe ¾-1″ of rain possible before it’s all said and done.
Rain falling into the wedge will keep temperatures quite chilly tomorrow. Lows in the low 40s will struggle to the upper 40s in the afternoon at best, with the immediate coast maybe touching 50°. The northeasterly breeze will make it feel even cooler at times, with wind chills in the upper 30s falling to the mid-30s by evening. Overall, Tuesday’s a good day for soup, chili, or whatever else comforts you when the weather outside is gray and rainy.
