Marine Weather and Tide Forecast for Red Bank, SC

NEAR TERM /THROUGH TONIGHT/
Key Message(s):

- Temperatures continue to moderate under sunny skies today

Current forecast remains on track as high pressure continues to dominate the Carolinas, although with the surface high shifting offshore the moisture return flow is evident in satellite imagery with fair weather cumulus already developing.
Temperatures are rising through the 70s en route to max temperatures in the lower to mid 80s under partly to mostly cloudy skies. Dewpoints are higher than yesterday so it will feel a bit more humid than Monday.

Tonight remains benign with another night of reasonable radiational cooling early, although a 25 knot low level jet may help keep boundary winds up a bit and limit cooling. Expect mostly clear skies light winds and lows in the upper 50s to around 60 degrees.

SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/
Key Message(s):

- Above normal temperatures, isolated convection Thu

An upper level ridge will build over the Southeast for Wednesday with the axis shifting just east on Thursday. With ridging over the area and southerly low level flow we can expect above normal temperatures. Highs each day will be in the mid to upper 80s. Ridging aloft on Wednesday will create a strong capping inversion precluding deep, moist convection. However when the ridge shifts east on Thursday, there may be some isolated showers or a thunderstorm in the extreme western FA aided by shortwave troughs riding along the top of the ridge. Deep southerly flow across the Deep South Thursday will allow PWATs to approach 1.5 inches in north/central GA into the SC Upstate.
Warm air aloft will still limit the threat of any severe weather. Lows in the low to mid 60s each night.

LONG TERM /FRIDAY THROUGH MONDAY/
Key Message(s):

- Scattered showers and thunderstorms Friday and Saturday - There is a low threat of severe weather on Friday

An upper level trough will dig into the Midwest on Friday. A prefrontal surface trough will dip into the Southeast on Friday followed by the main front on Saturday. Despite SW flow ahead of these surface features, moisture advection remains rather limited. NAEFS PWATs are near normal with deterministic GFS and ECMWF PWAT values around 1.25 or 1.33 inches. Lapse rates should be sufficient to produce deep, moist convection on Friday afternoon ahead of the prefrontal trough. With a deep inverted-v forecast sounding, there is some potential for damaging winds from thunderstorms. Rain chances continue into Saturday as the main cold front pushes into the area however with limited moisture available we expect convection to be scattered. It will be warmest on Friday with highs in the mid to upper 80s and cooler on Saturday and into early next week with near normal temps.

AVIATION /14Z TUESDAY THROUGH SATURDAY/
VFR conditions expected to persist through the period.

Surface high pressure continues to exert its dominance on the weather across the southeast. In general, this looks to remain VFR. As we get into the day, the dry high pressure should continue to yield partly/mostly sunny skies and southerly flow.
Winds of 5-10 knots are expected most of the day. Expect winds to fall off after 00z again with clear skies carrying us into the night. Forecasting vis restrictions at AGS overnight tonight as they've had it this morning briefly and the airmass shouldn't change much. As such, they'll likely see periodic ground fog introduce IFR or LIFR vis after 08z.

EXTENDED AVIATION OUTLOOK...VFR conditions will generally prevail, but some restrictions are possible in scattered convection with a cold front on Friday.
