Area forecast discussion, Aug 23, 4:15 PM EDT, 1 hour 31 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
415 PM EDT TUE AUG 23 2011

.SYNOPSIS...
A COASTAL TROUGH WILL LINGER ALONG THE COAST THROUGH THURSDAY.
HURRICANE IRENE COULD IMPACT THE AREA LATE FRIDAY INTO THE
WEEKEND. HIGH PRESSURE IS THEN EXPECTED TO BUILD BACK INTO THE
AREA EARLY NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
CURRENTLY AT THE SURFACE...HIGH PRESSURE IS CENTERED OVER THE MID-
ATLANTIC STATES WITH A TROUGH OF LOW PRESSURE EXTENDING FROM
NORTHERN FLORIDA OFF TO THE NORTHEAST INTO THE ATLANTIC WELL OFF
THE GEORGIA AND SOUTH CAROLINA COAST. MEANWHILE...HURRICANE IRENE
IS LOCATED WELL TO THE SOUTHEAST OF THE LOCAL AREA...JUST NORTH OF
HAITI LATE THIS AFTERNOON. RADAR IMAGERY SHOWS GENERALLY SCATTERED
SHOWER/THUNDERSTORM COVERAGE ACROSS THE AREA...WITH VISIBLE
SATELLITE IMAGERY SHOWING PARTLY TO MOSTLY CLOUDY CONDITIONS IN
PLACE. MAIN NEAR TERM CONCERN REVOLVES AROUND POPS.

HIGH PRESSURE NORTH OF THE REGION WILL BUILD EASTWARD AND INTO THE
WESTERN ATLANTIC OVERNIGHT...ALLOWING THE TROUGH OF LOW PRESSURE
WELL OFF THE CAROLINA AND GEORGIA COAST TO SHIFT SLOWLY BACK
TOWARD SHORE. EXPECT THAT CONVECTION LATE THIS AFTERNOON WILL
PROGRESS STEADILY INLAND WITH THE SEA BREEZE...AND WILL KEEP POPS
IN THE SLIGHT CHANCE/LOW CHANCE RANGE MOST LOCALES THROUGH EARLY
THIS EVENING. AFTER MIDNIGHT...EXPECT THAT INTERIOR LOCALES WILL
CLEAR OUT WITH RAIN FREE CONDITIONS PREVAILING. CLOSER TO THE
COAST HOWEVER...WIND SPEED AND DIRECTIONAL CONVERGENCE MAY ALLOW
FOR SOME ISOLATED SHOWERS TO ROLL IN OFF THE ATLANTIC...SO WILL
KEEP SLIGHT CHANCE/LOW CHANCE POPS GOING IN THESE LOCALES.
OVERNIGHT LOWS ARE EXPECTED TO BOTTOM OUT IN THE UPPER 60S WELL
INLAND AND IN THE LOWER 70S CLOSER TO THE COAST.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY/...
WEDNESDAY...CHANCES OF SHOWERS/THUNDERSTORMS WILL REMAIN IN THE
FORECAST WEDNESDAY AS SFC HIGH PRESSURE SLIDES OFF THE MID ATLANTIC
COAST AND A COASTAL TROUGH PERSISTS ALONG THE SOUTHEAST SOUTH
CAROLINA AND GEORGIA COASTLINE. PRECIP CHANCES APPEAR BEST OVER
COASTAL COUNTIES DURING EARLY AFTERNOON THROUGH EARLY EVENING HOURS.
THE COASTAL TROUGH WILL THEN MAKE A GRADUAL SHIFT INLAND AND BEGIN
TO WEAKEN AS HURRICANE IRENE MAKES A NORTHWARD MOVE TOWARDS THE
SOUTHEASTERN UNITED STATES. HIGH TEMPS WILL BE LIMITED TO THE UPPER
80S OVER MOST AREAS...ESPECIALLY WITH CLOUD COVER INCREASING ALONG
THE COASTAL TROUGH. A FEW LOCATIONS MAY TOUCH 90 DEGREES OVER INLAND
PORTIONS AWAY FROM THE COASTAL TROUGH. SHOWERS AND THUNDERSTORMS MAY
CONTINUE THROUGH WEDNESDAY NIGHT...BUT OVERALL COVERAGE WILL BE LESS
WITH THE COASTAL TROUGH WEAKENING. OVERNIGHT LOWS WILL BE IN THE
LOW/MID 70S.

THURSDAY...UNCERTAINTY REMAINS IN THE FORECAST THURSDAY WITH THE
APPROACH OF HURRICANE IRENE FROM THE SOUTH/SOUTHEAST AND A WEAK SFC
TROUGH FROM THE NORTHWEST. CURRENT MODEL GUIDANCE AND NHC FORECASTS
KEEP HURRICANE IRENE SOUTH OF THE AREA THROUGH THURSDAY NIGHT...BUT
SIGNIFICANT MOISTURE ADVECTION AND PINCHING OF THE GRADIENT NORTH OF
THE STORM MAY AID IN AFTERNOON CONVECTION ALONG A LINGERING COASTAL
TROUGH. HAVE MAINTAINED CHANCES OF SHOWERS AND THUNDERSTORMS FOR ALL
AREAS THROUGH THURSDAY EVENING AS A RESULT. A SLIGHT CHANCE TO
CHANCE OF SHOWERS/THUNDERSTORMS ARE POSSIBLE THURSDAY NIGHT AS
MOISTURE CONTINUES TO ADVECT ONSHORE WHILE THE WEAK SFC TROUGH
APPROACHES FROM THE NORTHWEST. OVERALL...HIGH TEMPS WILL AGAIN BE
LIMITED TO THE UPPER 80S FOR MOST AREAS DUE TO CLOUD COVER. A FEW
LOCATIONS MAY REACH 90 WELL INLAND. OVERNIGHT LOWS WILL BE IN THE
LOW/MID 70S.

FRIDAY...THE LATEST NHC FORECAST HAS THE CENTER OF HURRICANE IRENE
MAKING A NORTHWARD SHIFT THROUGH A WEAKNESS IN THE ATLANTIC
RIDGE...BUT REMAINING OFF THE SOUTH CAROLINA AND GEORGIA COAST
THROUGH FRIDAY AS AN H5 SHORTWAVE REACHES THE SOUTHEAST COAST
FROM THE NORTHWEST. STRONG NORTHERLY WINDS ALONG THE WESTERN PORTION
OF THE HURRICANE COULD DEVELOP ACROSS THE FORECAST AREA AT THIS
TIME...CREATING BREEZY TO WINDY CONDITIONS OVER LAND. PRECIPITATION
POTENTIAL WILL DEPEND HEAVILY ON THE TRACK AND SIZE OF THE TROPICAL
SYSTEM. IF THE FORECAST AREA REMAINS ON THE WESTERN SIDE OF THE
STORM...WHICH AT THIS TIME APPEARS TO BE THE CASE...RAINFALL
POTENTIAL MAY BE GREATLY REDUCED. HOWEVER...A SLIGHT WESTWARD
DEVIATION IN THE TRACK COULD RESULT IN SIGNIFICANTLY HIGHER IMPACTS
FROM WINDS AND RAIN ON FRIDAY...ESPECIALLY DURING LATE AFTERNOON AND
EVENING HOURS. HAVE MAINTAINED LIKELY POPS OVER THE COASTAL WATERS
FOR THE TIME BEING...WITH 40/50 POPS OVER LAND. HIGH TEMPS WILL BE A
FEW DEGREES COOLER THAN PREVIOUS DAYS AS CLOUD COVER EXPANDS OVER
THE REGION WITH THE APPROACH OF HURRICANE IRENE. EXPECT OVERALL
TEMPS TO BE LIMITED TO THE MID/UPPER 80S.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
IF CURRENT TRACK FORECAST VERIFIES...HURRICANE IRENE WILL BE
CLOSELY APPROACHING THE SOUTH CAROLINA COASTLINE FRIDAY
NIGHT...THEN STEADILY SHIFT NORTHWARD TOWARD THE NORTH CAROLINA
COAST BY SATURDAY. AS MENTIONED BEFORE...EVEN A SLIGHT DEVIATION
IN THE TRACK FORECAST COULD RESULT IN LARGE DIFFERENCES IN THE
IMPACTS FOR THE FORECAST AREA. SINCE THIS SCENARIO IS 4-5 DAYS
OUT...WOULD RATHER NOT FOCUS TOO MUCH ON DETAILS...WHICH ARE
LIKELY TO CHANGE AS THE EVENT NEARS.

SATURDAY...WINDY CONDITIONS ARE EXPECTED TO PERSIST INTO
SATURDAY...ESPECIALLY ACROSS SOUTH CAROLINA COUNTIES NEAREST TO
THE TROPICAL SYSTEM. WILL CONTINUE TO INDICATE FAIRLY HIGH POPS
FOR THE EXTENDED PERIOD...RANGING FROM 40 TO 60 PERCENT ACROSS THE
AREA. RAIN POTENTIAL WILL BE GRADUALLY SHIFTING NORTH WITH THE
PROGRESSION OF THE STORM. DAYTIME TEMPERATURES WILL BE A BIT
SUPPRESSED UNDER THICK CLOUD COVER...STRONG ONSHORE WINDS...AND
DECENT RAIN COVERAGE. HIGH TEMPERATURES WILL LIKELY REACH THE
MID TO UPPER 80S.

SUNDAY THROUGH TUESDAY...WEATHER CONDITIONS ARE EXPECTED TO
GRADUALLY IMPROVE INTO EARLY NEXT WEEK AS THE TROPICAL SYSTEM WILL
BE MOVING AWAY FROM THE REGION TO THE NORTH.

IT IS RECOMMENDED THAT ALL RESIDENTS AND VISITORS OF SOUTHEAST SOUTH
CAROLINA AND SOUTHEAST GEORGIA CONTINUE TO MONITOR FORECASTS FROM
THE NATIONAL HURRICANE CENTER REGARDING HURRICANE IRENE.

&&

.AVIATION /20Z TUESDAY THROUGH SUNDAY/...
CAN/T RULE OUT AN ISOLATED SHOWER/STORM BRIEFLY REDUCING CIGS
AND/OR VSBYS THIS EVENING AT THE SAV TERMINAL...SO WILL KEEP CB
MENTIONED THROUGH 23Z. OTHERWISE...EXPECT VFR CONDITIONS THROUGH
THE NIGHT. WITH AN EARLY SEA BREEZE PUSH WEDNESDAY...COULD SEE
SOME SHOWER AND MVFR CIG DEVELOPMENT AT EITHER TERMINAL BETWEEN
15Z AND 18Z.

EXTENDED AVIATION OUTLOOK...SHOWERS/THUNDERSTORMS COULD BRIEFLY
REDUCE VSBYS AND/OR CIGS EACH AFTERNOON/EVENING THROUGH THURSDAY.
TROPICAL STORM OR EVEN HURRICANE CONDITIONS ARE POSSIBLE FRIDAY AND
SATURDAY AS HURRICANE IRENE POTENTIALLY IMPACTS THE REGION.

&&

.MARINE...
HIGH PRESSURE WILL BUILD NORTH OF THE WATERS TONIGHT...WHILE A
TROUGH OF LOW PRESSURE LINGERS WELL OFFSHORE. EXPECT A BIT OF A
SURGE IN THE WINDS THIS EVENING...BUT CONDITIONS ARE EXPECTED TO
REMAIN WELL BELOW SMALL CRAFT THRESHOLDS.

A COASTAL TROUGH WILL LIKELY PERSIST ALONG THE SOUTH CAROLINA AND
GEORGIA COAST WEDNESDAY BEFORE WEAKENING THURSDAY. THIS PATTERN WILL
LIKELY MAINTAIN SOLID ONSHORE FLOW AND INCREASE THE POTENTIAL FOR
SCA LEVEL SEAS IN THE OUTER WATERS BY LATE WEDNESDAY. SCA TIMING
WILL BE HIGHLY DEPENDENT ON THE LOCATION OF HURRICANE IRENE AS IT
MAKES A NORTHWARD MOVE TOWARDS THE COASTAL WATERS...BUT SOLID SCA/S
ARE LIKELY BY THURSDAY AFTERNOON BASED ON THE CURRENT NHC FORECAST
TRACK. SHOWERS AND THUNDERSTORMS WILL ALSO BE POSSIBLE WHILE THE
COASTAL TROUGH LINGERS THROUGH THURSDAY EVENING.

HURRICANE IRENE STILL POSES A CONSIDERABLE THREAT TO THE COASTAL
WATERS FRIDAY INTO THE WEEKEND...ALTHOUGH THERE CONTINUES
TO BE SIGNIFICANT UNCERTAINTY IN THE TRACK FORECAST THIS FAR OUT.
LATEST NATIONAL HURRICANE CENTER TRACK SUGGESTS TROPICAL STORM
AND/OR HURRICANE CONDITIONS WILL BE POSSIBLE FRIDAY NIGHT AND
SATURDAY...WITH WINDS POTENTIALLY UP TO 65 KT IN THE NORTHERN WATERS
AND SEAS APPROACHING 17 TO 20 FT. MARINERS ARE ADVISED THAT TROPICAL
CYCLONE WATCHES AND/OR WARNINGS COULD BE REQUIRED WITH LATER
FORECAST ISSUANCES AND COULD CONTINUE THROUGH THE WEEKEND. ALL
MARINERS ARE THUS STRONGLY ADVISED TO CONTINUE TO MONITOR THE
PROGRESS OF IRENE FROM ADVISORIES ISSUED BY NATIONAL HURRICANE
CENTER.

RIP CURRENTS...SWELLS FROM IRENE COULD ARRIVE AS EARLY AS THURSDAY
EVENING...AND CONTINUE FOR SEVERAL DAYS. THIS WILL RESULT IN AN ENHANCED
RISK OF RIP CURRENTS.

&&

.TIDES/COASTAL FLOODING...
ASTRONOMICAL HIGH TIDES WILL DEVELOP ACROSS THE AREA LATE THIS
WEEK...AND DEPENDENT UPON ANY IMPACTS FROM IRENE...THERE COULD BE
SOME COASTAL FLOODING AND BEACH EROSION CONCERNS BEGINNING FRIDAY.

&&

.CHS WATCHES/WARNINGS/ADVISORIES...
GA...NONE.
SC...NONE.
MARINE...NONE.
