Area Forecast Discussion National Weather Service Charleston SC 411 PM EDT Fri Apr 19 2024

SYNOPSIS
A slow moving front will bring unsettled weather to the region Saturday through early next week. High pressure will then return and prevail into the middle of next week.

NEAR TERM /UNTIL 6 AM SATURDAY MORNING/
Despite moderate instability in place, NVA and downslope flow are suppressing most of the convection this afternoon. The sea breeze is still pinned near the coast due to the westerly flow.
Later tonight a weak shortwave will move through southern SC, which could produce an isolated shower or tstm over northern areas, but in general dry conditions expected. Lows will be in the mid 60s.

SHORT TERM /6 AM SATURDAY MORNING THROUGH MONDAY/
Mid-level ridging will be centered across the southern Gulf of Mexico Saturday with a shortwave over southeast Texas slowly heading east. Across eastern Canada, a longwave trough will slowly translate off the coast with a weak cold front oozing to the south. The first batch of precipitation is forecast to arrive with the shearing out wave (originating from Texas) Saturday afternoon into evening. PWATs ahead of the wave Saturday are forecast to be around 1.4" along with warm cloud depths around 7kft. Initially, precipitation will likely struggle to hold together across the Low Country due to the dry air. Expect high temperatures in the upper 80s.

By 5 PM and 8 PM showers and thunderstorms will fill in towards the coast Saturday. MLCAPE values are forecast to be around 1000 J/kg which will support thunder across all zones. The wave will then start to exit the coast Sunday morning with precipitation temporarily coming to an end and a weak cold front oozing to the SC coastline.

Another wave will then approach the area Sunday afternoon and is slightly more amplified that in previous runs. As this occurs, surface cyclogenesis will occur off the coast of South Carolina in association with the stalled frontal zone. Some global guidance is indicating weak FGEN forcing occurring around 875 mb with the QPF field responding by arching back into a slight banded feature. Given that the forcing is weak, most of the area will likely see precipitation Sunday afternoon, but the focus of the QPF being towards the Midlands of SC. Expect high temperatures in the 60s interior SC Sunday, and upper 70s forecast over GA (or south of the cold front).

Sunday night into Monday, temperatures will fall into the 50s across the region. Latest global guidance continues to struggle with Monday as another mid-level low, potentially rather amplified, will cross the area. The latest run of the GEFS is by far the most amplified, while the GEPS is the least amplified.
For now, have introduced PoPs into the forecast for Monday to account for this.

LONG TERM /MONDAY NIGHT THROUGH FRIDAY/
Strong DAVA will set in across Georgia and South Carolina for Tuesday as a mid-level low pressure exits the region. Temperatures will fall below normal with no precipitation expected. Wednesday into Thursday a strong closed low pressure is forecast to move across the Great Lakes with the core of the DCVA remaining well north of the area. Another cold front is then forecast to cross the area Thursday into Friday. No precipitation is currently expected with this frontal passage either.

AVIATION /19Z FRIDAY THROUGH WEDNESDAY/
VFR conditions will prevail at CHS/JZI/SAV terminals through 18Z Saturday.

Extended Aviation Outlook: A slow moving front will bring multiple rounds of flight restrictions late Saturday through Sunday. Further restrictions are possible Monday as low level moisture remains trapped behind a frontal inversion. VFR conditions are then forecast Tuesday and Wednesday as surface high pressure approaches from the west.

MARINE
Weak S to SW flow will continue through tonight as high pressure remains offshore and a front is stalled inland. Winds will be no higher than 10-15 kt.

Saturday through Wednesday: South to southwest winds will persist Saturday as a cold front slowly oozes towards the coast. Weak surface cyclogenesis will then occur Sunday afternoon with winds turning around from the northeast. Winds will then continue to increase in speed and be sustained 20 to 25 kts with gusts 25 to to 30 kt. The highest probability for Small Craft Advisories appear to be in the Atlantic waters adjacent to Charleston. Expect seas 4 to 6 ft. Winds will start to relax from the northeast Tuesday morning and slowly veer around from the southwest Tuesday afternoon into Wednesday.

CHS WATCHES/WARNINGS/ADVISORIES
