SYNOPSIS
A cold front will move through today, then high pressure will build in through Tuesday. A cold front could affect the area next Wednesday.
NEAR TERM /THROUGH TONIGHT/
Today: The cold front is now offshore and rain is slowly ending along the coast. It will take several more hours before the last of the rain activity fully exits off the middle South Carolina coast. Winds are starting to become gusty with the onset of cold air advection. Gusts 25-30 mph should be common for many areas today. There are signs that a few showers could redevelop this afternoon (mainly interior Southeast Georgia) as the base of the upper trough swings through. Not overly confident on this scenario given soundings show the atmosphere drying out pretty quickly later in the day as downslope flow off the southern Appalachians dominates. Highs from the lower-mid 60s over the Charleston Tri-County to upper 60s elsewhere away from the immediate coast look on track.
Tonight: Clear skies will encompass the area as high pressure builds in from the west. Although winds never fully decouple in most places, there is enough cold advection and some radiational cooling to allow for temperatures to drop to the 40s just about everywhere. If winds do go calm, a few upper 30s are possible in normally colder rural interior sections.
SHORT TERM /FRIDAY THROUGH SUNDAY/
Deep layered ridging expected Friday through Sunday, with dry conditions and warming temperatures. Sunny skies should prevail Friday and Saturday, then high cirrus should overspread the area on Sunday. High temps will go from lower 70s Friday to mid 70s Saturday and lower 80s Sunday.
LONG TERM /SUNDAY NIGHT THROUGH WEDNESDAY/
Above normal temperatures will continue Monday into Tuesday as ridging persists. Monday will be dry, as well as most of Tuesday, though an approaching upper shortwave could bring a few showers into far western areas late Tuesday. A potent upper trough will push a cold front through the area on Wednesday, potentially accompanied by scattered showers and isolated thunderstorms. Temps will cool down a bit by Thursday with drying conditions.
AVIATION /14Z THURSDAY THROUGH MONDAY/
KCHS/KJZI/KSAV: Showers will gradually taper off and come to an end this morning in wake of a cold front and wave of low pressure. IFR ceilings at all sites will continue with a persistent low level inversion trapping moisture underneath.
MVFR returns during the afternoon as mixing heights climb, then VFR finally moves back in late, as high pressure builds from the west. Gusty N winds will occur through the day, peaking around 25 kt, before diminishing considerably toward sunset.
Extended Aviation Outlook: VFR conditions will prevail.
MARINE
Today: A cold front and wave of low pressure is passing through the waters early this morning, lifting off to the northeast as it deepens thereafter. There's a tightening of the gradient that occurs between these features and high pressure from Texas to Ohio, plus some cold advection, which will produce NW and N winds as high as 20 or 25 kt, with even some stronger gusts. As a result, Small Craft Advisories are in effect for all waters, including Charleston Harbor. Sea height is cut down some by the offshore fetch, but given the strength of the winds, they'll still be as high as 3-5 ft nearshore, 4-6 ft offshore.
Tonight: High pressure continues to build in from the west. The combination of weak cold advection, steady isallobaric pressure climbs, and a modest gradient will keep winds elevated. Small Craft Advisories will continue for at least the Charleston County Atlantic waters, and the outermost Georgia waters.
Friday through Monday: Winds will turn to the SW on Friday as high pressure redevelops off the FL coast. Wind speeds will increase over the weekend as the gradient tightens between the surface high over the southwest Atlantic and a developing surface trough inland. A further tightening of the gradient is expected Tuesday into Wednesday as a cold front approaches from the west. A brief period of Small Craft Advisory gusts is possible Saturday afternoon over the Charleston nearshore waters. We could be close to advisory again Tuesday into Wednesday, mainly due to gusts near 25 kt.
