Area Forecast Discussion National Weather Service Charleston SC 801 PM EDT Tue Aug 11 2020

SYNOPSIS. The region will remain positioned between Atlantic high pressure well to the east and inland low pressure. A weak cold front could approach the area over the weekend and linger in the vicinity into early next week.

NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/. Early this evening: Mostly scattered coverage of thunderstorms this evening, primarily impacting southeast Georgia. Most of the activity has been fairly weak, except for one storm that has pulsed up with 60+ dBZ over the -20 C height (nearly 27 kft) and over 100 knots of storm top divergence. This storm is currently warned for and will be impacting Fort Stewart and the Hinesville area. Otherwise, storms are progressing from north to south and should stay just in the scattered coverage range through the rest of the evening. Focus for convection will then shift to the coastal waters yet again and rain chances have been constructed to reflect this. Overall, no significant fog or stratus concerns.

SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY/. A broad, deep layer trough remains inland with a Atlantic high pressure to the east-southeast. South-southwest low-level flow is expected to become onshore near the coast each afternoon due to the sea breeze. The sea breeze and convective outflow boundaries will be the main focus for any showers and thunderstorms. Generally chance to low-end likely PoPs are forecast for the afternoon and early evening showers and thunderstorms each day with an isolated strong to severe thunderstorm possible. Upper level flow remains weak and will continue to result in slow-moving or virtually stationary storms. With plenty of deep layer moisture and PWATs near 2 inches, some storms could produce locally heavy rainfall. High temperatures remain in the normal range, mostly in the lower 90s with upper 80s on Friday. Overnight lows in the lower to mid 70s, except upper 70s along the immediate coast.

LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/. Models continue to lack consistency in the long term period. Broad troughing aloft appears to shift towards the East Coast over the weekend into early next week. At the surface, a weak front could approach the region and then linger over or near the area. This setup will generally favor higher than normal rain chances, although given a good amount of disagreement between models, refinements will be needed. Temperatures will be near climo.

AVIATION /00Z WEDNESDAY THROUGH SUNDAY/. VFR conditions should prevail at KCHS and KSAV through 00z Thursday. Through the rest of the evening, thunderstorms should stay just west of KSAV, though it is possible for one to pass within the vicinity. No concerns at KCHS. We expect additional thunderstorms Wednesday afternoon, but it is too early to introduce any thunder into the TAF's.

Extended Aviation Outlook: Flight restrictions possible in showers/thunderstorms each day, mainly in the afternoon/evening.

MARINE. Tonight: No significant concerns as far as winds/seas but some stronger storms could cause locally hazardous conditions mainly after midnight.

Wednesday through Saturday: No highlights are expected through the week. The waters will remain between Atlantic high pressure to the east and a broad area of lower pressure well inland. A weak upper low is expected to transition to a mid- level trough and move offshore by early Wednesday where convection could linger offshore. In general, southerly winds of 15 knots or less and seas of 3 feet or less are expected. An afternoon sea breeze will turn winds southerly/onshore near the coast each afternoon. Scattered showers and thunderstorms are expected mainly late night and early morning.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
