Friday looks to be a rather chilly day across the Lowcountry despite decreasing clouds and quite a bit of sunshine. Highs will struggle into the mid-40s as cold high pressure builds into the area in the wake of Thursday’s storm system.
There is a small possibility of a few flurries generally north of I-26 in the early morning hours as one last disturbance swings through the area. This probability is extremely low as cold air will be chasing the moisture out of the area, so please manage your expectations accordingly. Elsewhere, a shower or two cannot be totally ruled out. Precipitation — if any — ends by sunrise.
Minor coastal flooding may become an issue in the morning as gusty northeast winds persist across the area. Tide levels may reach 7-7.2′ in the harbor with the 6:34 AM high tide. It is possible that a coastal flood advisory could be needed. Vulnerable roads in downtown Charleston, particularly those on the western edge of the peninsula near the Citadel, could be affected by these tides. Be ready for brief diversions due to water on the road.
Be ready for a very cold night Friday night into Saturday morning, as many locations will dip into the mid-20s away from the immediate coast. Be ready to protect plants, pipes, pets, and people from arguably the coldest air of the season.
