Marine Weather and Tide Forecast for Barnwell, SC

NEAR TERM /UNTIL 8 AM MONDAY MORNING/
Key Message(s):

- Warm and humid conditions continue overnight with a few showers around.

Not much change in the overall pattern with high PWAT's, modest instability, but very limited forcing. A weak shortwave pushed across NC and VA earlier this evening, and based on water vapor imagery, seems to have driven some subsidence across our area.
So, not really expecting much in the way precip overnight with good agreement in the hi-res models. Some overnight and early morning fog-stratus is possible but mid-level clouds will likely mitigate it for the most part.

SHORT TERM /8 AM MONDAY MORNING THROUGH WEDNESDAY/
A deep layered ridge will expand from the western Atlantic into the Southeast United States early next week, bringing a pretty typical summertime pattern to the area. High temps will increase a degree or two each day with values in the low to mid 90s.
Dewpoints solidly in the 70s will combine to produce 100-105F heat indices each day. Increasing mid-level subsidence should limit diurnal convective coverage, though with 1500-2000 J/kg CAPEs each day, isolated to scattered coverage expected.

LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/

AVIATION /00Z MONDAY THROUGH FRIDAY/
VFR conditions generally expected through the period with possible brief restrictions in predawn stratus at AGS/DNL.

Afternoon convection remains isolated and should not have much impact on terminals although a shower may move over OGB so included a tempo there. Otherwise, southerly winds gradually weaken through the night less than 5 knots. Models are not as aggressive with stratus tonight but there are some suggestions if it happens it would be in the CSRA so have included a tempo there for MVFR cigs 09z-13z. Winds should pick up to around 8 to 10 knots after 15z with VFR cumulus cloud development and scattered afternoon convection.

EXTENDED AVIATION OUTLOOK...Brief restrictions are possible each afternoon/evening with typical summertime convection.
Patchy early morning fog and stratus may also cause some restrictions.
