Area Forecast Discussion National Weather Service Charleston SC 116 PM EST Sat Dec 2 2023

SYNOPSIS
A cold front will approach from the west today, before passing through the area Sunday evening. High pressure will then prevail through much of next week.

NEAR TERM /THROUGH TONIGHT/
Rest of Today: Little change is expected in the pattern aloft, SW flow will continue to prevail. At the surface the region will remain well within the warm sector of a low pressure system positioned to the west. Rain has overspread the panhandle of FL and areas to the south of the forecast area, with only some light showers impacting the far southern zones. Models have continued to back off on POPs this afternoon as the ongoing showers and convection to the south essentially rob the local area of moisture. As the afternoon progresses the shower activity should push northeastward into the forecast area and most locations should see some rainfall by the late afternoon hours. There is a slight chance of a thunderstorm this afternoon, as instability reaches around 100-200 J/kg. However, wild fields are not impressive so the severe threat remains near zero. Generally rainfall totals will likely be below 0.5 inches.
Temperatures will remain above normal, in the low 70s across the region.

Tonight: The area of rainfall with embedded isolated thunderstorms will push through during the evening and we should see lull in rain coverage by around midnight. Other than an occasional passing shower or area of light rain, much of the late night period is expected to be dry as the upstream cold front draws closer. We will have to watch for fog development beginning in the evening once again. The best chance for more significant fog will be along the coast where marine fog could occasionally push onshore. There is a chance for some locally dense fog, but confidence isn't particularly high as low-level winds are expected to pick up late. Temperatures will be mild once again, with low to mid 60s for lows.

SHORT TERM /SUNDAY THROUGH TUESDAY/
The forecast area will remain in the warm sector into Sunday ahead of a cold front. Shower activity will linger through the morning and into the afternoon, then rain chances should be on a decreasing trend during the latter half of the day. Coverage doesn't look particularly high and PoPs were lowered largely into the 40-50% range for most locations. Highs are expected to reach the mid 70s. Dry weather is then expected for much of the overnight as deeper moisture pushes offshore with the front.
Lows will range from the upper 40s/near 50 far inland to mid/upper 50s closer to the coast.

Quiet and dry weather will persist Monday and Tuesday as PWats fall to under 0.5 inches - well below climo. High pressure will be the primary surface feature, however a couple areas of low pressure will pass by to the north. Highs in the upper 60s/near 70 on Monday will cool to the low 60s for Tuesday. Lows Monday night will mainly be in the low to mid 40s.

LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/
Cooler high pressure will settle into the region for midweek following passage of a dry cold front late Tuesday night. The airmass will begin to moderate late week as the high shifts offshore. No significant weather concerns are expected through the period with rain-free conditions in the forecast.

AVIATION /18Z SATURDAY THROUGH THURSDAY/
KCHS/KJZI: Conditions to start the 18Z TAF period will be VFR, however moments of MVFR cig/vis are expected at KJZI and are reflected in a TEMPO group. Light rainfall is expected to move in from the southwest later this afternoon, impacting both terminals. In addition to the rainfall, low cigs are expected to move in overnight with fog/low stratus.

KSAV: MVFR conditions will start off the 18Z TAF period as well as some light rain showers likely ongoing, or will be ongoing soon. Rain showers will continue to work their way into the area through the afternoon. Additionally, low cigs are expected to move in later tonight with fog/low stratus.

Extended Aviation Outlook: Flight restrictions in low clouds and showers will likely persist into Sunday afternoon.
Conditions should then improve to VFR for Monday.

MARINE
Today through tonight: Winds today are expected to mostly be southerly with speeds of 10 knots or less. Late tonight winds should turn more southwesterly and begin to increase more into the 10-15 knot range. Seas should be highest this morning with 2-4 feet across all waters and up to 5 feet in the outer Georgia waters and near the 20 nm line in the Charleston County waters.
Overnight, seas should average 2-4 feet.

Fog: Local webcams show that patchy fog continues to impact the Charleston Harbor and some SC coastal communities. Showers and isolated thunderstorms are expected to spread in during the afternoon. This activity will pass through later this evening and then we could again see fog and low stratus issues overnight. Any sea fog that develops tonight could linger over the coastal waters into Sunday. Have included mention of patchy fog through mid-day Sunday, but this could need to be expanded in coverage and time. Guidance indicates improving conditions during the latter half of Sunday.

Sunday through Thursday: Southwest winds will persist on Sunday ahead of a cold front. Winds will turn westerly following fropa and increase later Monday into Monday night. A brief period of gusts near 25 knots will be possible mainly across the Charleston county waters and outer Georgia waters but looks pretty marginal at this point. Perhaps the better chance for Small Craft Advisories will be Wednesday behind another cold front. Conditions will improve for Thursday as high pressure shifts overhead.
