Details are coming into focus around what will be quite a strong storm for the Eastern Seaboard for Christmas Eve. Model guidance is in unanimous agreement for a strong band of showers and thunderstorms ahead of the cold front that could produce occasional damaging wind gusts during the afternoon and early evening hours. The good news is that this activity should get out of here by the time Santa is ready to make his rounds in the Lowcountry.
Wednesday will be the last rain-free shopping day before Christmas. Cloud cover will be filling in as the day goes on ahead of what looks to be a fairly potent storm system for Christmas Eve. Temperatures around the area will start out chilly — low 40s, with wind chills around 37-38° possible with a light breeze — before warming into the mid-60s despite the cloud cover. A shower or two can’t be ruled out closer to midnight Wednesday as well.
We have a rather gorgeous Tuesday ahead as high pressure moves along to our northeast. Downslope flow will continue, allowing temperatures to warm back into the low 60s for the afternoon after starting out in the low 40s under full sunshine.
