Area Forecast Discussion National Weather Service Charleston SC 357 AM EDT Sat Aug 8 2020

SYNOPSIS. A stationary front will linger to the west through the weekend before dissipating. The region will then be positioned between Atlantic high pressure centered offshore and an inland area of broad low pressure.

NEAR TERM /UNTIL 6 PM THIS EVENING/. This morning, isolated showers/thunderstorms could develop along mesoscale boundaries just about anywhere across the region, especially across the Charleston County region. However, guidance suggests that most diurnal showers/ thunderstorms could hold off until mid to late afternoon, as the sea breeze pushes inland and subsequent outflow boundaries develop. Capped maximum PoPS at 40-50 percent inland, but locally greater PoPs could eventually be required. PWAT values exceeding 2 inches, light steering flow and typically strong instability could support locally heavy rainfall and isolated/pulse episodes of damaging wind gusts this afternoon.

Outside thunderstorms, high temperatures in the lower/middle 90s will be common away from the beaches, and heat index values will once again push into the 100-108F range at many locations.

SHORT TERM /6 PM THIS EVENING THROUGH TUESDAY/. Tonight: Guidance suggests that showers/thunderstorms with locally heavy rainfall and even an isolated threat for brief damaging wind gusts could persist well into the evening. Overnight, the focus for convection should once again shift from inland counties toward the coast, especially the SC coast and adjacent coastal waters. Low temperatures should again range from the lower to middle 70s inland to the upper 70s/lower 80s at the coast.

All models show that the region will remain between Atlantic high pressure well to the east-southeast and deep layer troughing well inland. Expect a rather typical diurnal pattern of scattered to numerous mainly afternoon and evening showers and thunderstorms each day, driven mostly by the afternoon sea breeze, and then outflow boundaries later in the afternoon and evening. Have kept high end chance to low end likely PoPs. Relatively light, unidirectional winds and PWs near 2 inches, could produce some training of convection, providing the potential for locally heavy rainfall each day. Highs near to slightly above normal in the lower to mid 90s, warmest well inland. Lows in the lower 70s well inland and mid to upper 70s else where.

LONG TERM /TUESDAY NIGHT THROUGH FRIDAY/. Little change in the large scale pattern, with a deep layer Atlantic ridge situated to the east and deep layer trough of low pressure well to the west. Global models show that an upper trough may try to sharpen well to the west during this period, as well as an increase in deep layer moisture. With this combination, guidance continues to show likely afternoon/early evening PoPs each day. A little uncomfortable going with such high PoPs this far out, but blended PoPs have been consistently high, and those PoPs collaborate well with surrounding offices. Highs will continue near normal, around 90 to the lower 90s. Lows in the lower to mid 70s.

AVIATION /08Z SATURDAY THROUGH WEDNESDAY/. Occasional MVFR ceilings are possible at both terminals overnight into early Saturday. Also, given latest guidance trends, will shift timing of VCTS/CBs until after 20z.

Extended Aviation Outlook: Expect Scattered to possibly numerous showers and thunderstorms, mainly afternoon and evening each day, which may cause brief flight restrictions. There is still a chance for late night Atlantic based stratocu, mainly at KCHS.

MARINE. Today and tonight: The land breeze could support a threat for isolated waterspouts near the coast this morning. Will continue to assess this potential. The sea breeze will turn coastal winds to the S/SE at 10 to 15 knots this afternoon/early evening, then S/SW winds will average 5-15 kt tonight, perhaps turning offshore at less than 10 kt if the land breeze again pushes into nearshore waters late. Farther offshore, S/SW winds will average 10-15 kt through tonight. seas will average around 2 feet.

No highlights expected through the period. A very persistent summer- time pattern is expected to remain in place with an Atlantic ridge to the east and lower pressure well inland. This will result in light southerly winds of 15 knots or less and seas 1 to 3 feet, highest offshore. Winds will likely become onshore each afternoon near the coast. Scattered mainly night time and morning showers and thunderstorms.
