It’s been quite a soggy weekend, with rain totals in many spots exceeding 1″ just today as seemingly relentless moisture pushed atop a cold air damming wedge, keeping the weather wet and chilly as temperatures have barely left the low 40s over the past two days.
Well, the good news is that things are changing, and that we will even see the sun at times this week! (The weekend looks good, too!) But, there will be more unsettled weather before it’s all said and done.
A cold air damming regime will remain in place over the weekend, with plentiful moisture and upper-level energy keeping numerous showers in the forecast along with chilly temperatures. This rain will be no joke — NWS is forecasting 1-3″ across the area by Monday morning, with the higher rain totals generally to be found inland of 17. The wedge of cold air nestled between the Appalachians and the Atlantic and its associated persistent overcast will keep temperatures well below normal (62° is the normal high for this time of year).
Despite what some weather apps were showing this time last week, no precipitation type issues are in the forecast this weekend as the core of the coldest air remains well to our north and west.
Unsettled weather will continue for Friday and into Valentine’s weekend as the overall pattern remains quite…well, gross.
We start Friday out with dense fog blanketing coastal areas and some showers in the area. (Use those low beams.) Showers will be off and on throughout the day. Temperatures are not going to move a whole heck of a lot overall as high pressure wedges down into South Carolina and Georgia, setting up cold air damming that will characterize much of the rest of the weekend’s weather. The forecast high of 57° at the Charleston airport should be realized fairly early in the day before the wedge front slides through.
Moisture overrunning the cold air damming wedge will keep clouds and rain in the forecast for much of the weekend. It’s unlikely that it will rain all the time, but it could rain at any time. Temperatures will run several degrees below normal beneath the cold wedge, but while it will feel chilly, temperatures will remain far too warm for any precipitation type issues here in the Lowcountry.
Watch out for fog Thursday morning as you commute — it could turn dense at times, so you’ll want to ensure you’re using the low beams and allowing a little extra time to get where you need to go.
After the fog clears up, we’ll still see mostly cloudy skies, but we could see a few peeks of sun at times. Regardless, temperatures look to warm to near 70° in the afternoon ahead of a cold front. Rain chances will increase as the day goes on, but don’t expect much in the way of widespread rainfall until after dark.
