AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
416 PM EDT MON AUG 22 2011

.SYNOPSIS...
A COLD FRONT WILL PUSH THROUGH THE AREA TONIGHT...THEN STALL OUT JUST
OFFSHORE TUESDAY BEFORE DISSIPATING ON WEDNESDAY. HURRICANE IRENE
COULD IMPACT THE AREA LATE IN THE WEEK AND OVER THE WEEKEND.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
CURRENTLY AT THE SURFACE...A COLD FRONT STRETCHES FROM NEAR FLORENCE
TO ORANGEBURG...SOUTHWESTWARD TO NEAR VIDALIA. DEWPOINTS HAVE FALLEN
INTO THE LOWER/MIDDLE 60S BEHIND THE COLD FRONT...BUT REMAIN IN THE
LOWER/MIDDLE 70S IN ADVANCE OF IT. MEANWHILE ALOFT...A DISTINCT
SHORTWAVE TROUGH IS EVIDENT IN WATER VAPOR IMAGERY STRETCHING FROM
THE CENTRAL CAROLINAS INTO SOUTHWESTERN GEORGIA...WITH A NICE UPPER
LEVEL SPEED MAX/JET NOW SHIFTING INTO NORTHERN GEORGIA AND UPSTATE
SOUTH CAROLINA. RADAR IMAGERY SHOWS SCATTERED SHOWER/THUNDERSTORM
COVERAGE ACROSS THE LOCAL AREA...WITH SATELLITE IMAGERY INDICATING
PARTLY TO MOSTLY CLOUDY SKIES. MAIN NEAR TERM CONCERNS REVOLVE
AROUND ONGOING SEVERE THREAT AND THE OVERNIGHT POP TREND.

THE COLD FRONT IS EXPECTED TO CONTINUE TO PUSH TOWARD THE COAST THIS
EVENING AND SETTLE SOUTH OF THE FORECAST AREA OVERNIGHT. THE
COMBINATION OF UPPER LEVEL SUPPORT FOR ASCENT...THE SURFACE COLD
FRONT...INLAND PUSHING SEA BREEZE...AND PLENTY OF SURFACE BASED
INSTABILITY SHOULD ALLOW FOR CONTINUED SHOWER/THUNDERSTORM
DEVELOPMENT INTO THE EVENING. AS A RESULT WILL CONTINUE TO CARRY
CHANCE/LIKELY POPS THIS EVENING BEFORE TRANSITIONING TO SLIGHT
CHANCE OR RAIN FREE CONDITIONS AFTER MIDNIGHT. WILL CONTINUE TO
MENTION THE THREAT FOR SEVERE DAMAGING WINDS INTO THE EVENING...WITH
THE THREAT EXPECTED TO DIMINISH AFTER SUNSET. OVERNIGHT LOWS SHOULD
BOTTOM OUT IN THE LOW TO MID 70S MOST LOCALES...WITH A FEW AREAS FAR
INLAND DROPPING TO AROUND 70.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH THURSDAY/...
A WEAK COLD FRONT WILL DRIFT SOUTH AND DISSIPATE OVER SOUTHEAST
GEORGIA/NORTHERN FLORIDA LATE TUESDAY WHILE SFC HIGH PRESSURE BUILDS
FROM THE NORTH. AT THE SAME TIME...WEAK MID/UPPER LVL TROUGHING WILL
GRADUALLY SHIFT OFF THE MID ATLANTIC COAST...CAUSING A WEAKNESS IN
THE WESTERN ATLANTIC RIDGE THROUGH MIDWEEK. HAVE MAINTAINED SLIGHT
CHANCE TO CHANCE OF SHOWERS/THUNDERSTORMS TUESDAY AFTERNOON WITH
HIGH TEMPS REACHING AROUND 90 DEGREES AND PERSISTENT ONSHORE FLOW
RESULTING IN PWATS AROUND 2 INCHES OVER THE CWA. HIGHEST POPS WILL
REMAIN NEAR THE VICINITY OF THE DISSIPATING FRONT AND SEABREEZE OVER
SOUTHERN MOST AREAS IN SOUTHEAST GEORGIA. EXPECT MOST ACTIVITY TO
DISSIPATE TUESDAY EVENING WITH THE LOSS OF DAYTIME HEATING...BUT AN
ISOLATED SHOWER AND/OR THUNDERSTORM WILL REMAIN POSSIBLE ALONG THE
SOUTHEAST SOUTH CAROLINA AND GEORGIA COAST TUESDAY NIGHT. OVERNIGHT
LOWS WILL REACH THE LOW/MID 70S.

CHANCES OF PRECIP WILL INCREASE SLIGHTLY WEDNESDAY AS SFC HIGH
PRESSURE SLIDES OFF THE MID ATLANTIC COAST AND A WEAK COASTAL TROUGH
DEVELOPS ALONG THE SOUTHEAST COAST. PRECIP CHANCES APPEAR BEST
WEDNESDAY AFTERNOON/EVENING WHEN THE COASTAL TROUGH BECOMES MORE ENHANCED
AS HURRICANE IRENE CONTINUES TO APPROACH THE AREA FROM THE
SOUTH/SOUTHEAST. OVERALL HIGH TEMPS WILL REMAIN IN THE UPPER 80S
OVER MOST AREAS...ESPECIALLY WITH CLOUD COVER INCREASING THROUGH THE
AFTERNOON. A FEW LOCATIONS MAY TOUCH 90 DEGREES OVER INLAND PORTIONS
OF SOUTHEAST GEORGIA. SLIGHT CHANCE TO CHANCE OF PRECIP WILL
CONTINUE WEDNESDAY NIGHT...MAINLY IN ASSOCIATION WITH THE COASTAL
TROUGH LINGERING ALONG THE SOUTHEAST SOUTH CAROLINA AND SOUTHEAST
GEORGIA COASTS. OVERNIGHT LOWS WILL BE IN THE LOW/MID 70S.

A LARGE AMOUNT OF UNCERTAINTY REMAINS IN THE FORECAST THURSDAY WITH
THE APPROACH OF HURRICANE IRENE FROM THE SOUTH/SOUTHEAST AND A SFC
TROUGH FROM THE NORTHWEST. AT THIS TIME...MODEL GUIDANCE AND NHC
FORECASTS KEEP HURRICANE IRENE SOUTH OF THE AREA THROUGH THURSDAY
NIGHT. SIGNIFICANT MOISTURE ADVECTION AND PINCHING OF THE GRADIENT
NORTH OF THE HURRICANE HOWEVER...WILL LIKELY AID IN SCATTERED
CONVECTION OVER THE FORECAST AREA. DESPITE AN EASTWARD TREND IN THE
FORECAST TRACK OF HURRICANE IRENE...CHANCES OF SHOWERS AND
THUNDERSTORMS ARE POSSIBLE THURSDAY NIGHT AS MOISTURE CONTINUES TO
ADVECT ONSHORE AND CONVERGENCE OCCURS ALONG THE SFC TROUGH
APPROACHING FROM THE NORTHWEST. OVERALL HIGH TEMPS WILL REMAIN IN
THE UPPER 80S WITH INCREASING CLOUD COVER. OVERNIGHT LOWS WILL BE IN
THE LOW/MID 70S.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
MUCH OF THE EXTENDED FORECAST WILL BE HIGHLY DEPENDENT ON THE
DEVELOPMENT AND PROGRESSION OF HURRICANE IRENE. ALTHOUGH NUMERICAL
MODELS HAVE BEEN FAIRLY CONSISTENT IN TRACKING THE SYSTEM TOWARD THE
SOUTHEAST COAST.

HAVE ATTEMPTED TO INTRODUCE A LITTLE MORE SPECIFICITY IN THE POP
FORECAST FOR FRIDAY AND SATURDAY...AS THESE APPEAR TO BE THE FAVORED
DAYS FOR ANY SIGNIFICANT PRECIPITATION ASSOCIATED WITH IRENE. DECENT
AGREEMENT BETWEEN THE GFS AND ECMWF REGARDING PRECIPITATION
COVERAGE HAS SUPPORTED INCREASING RAIN CHANCES FROM EAST TO
WEST...PEAKING AT LIKELY IN THE 60 PERCENT RANGE BY THE DAYTIME
HOURS SATURDAY. BEST POTENTIAL FOR AT LEAST BREEZY CONDITIONS WILL
ALSO BE FRIDAY THROUGH THE WEEKEND...WHEN THE STORM COULD BE
TRACKING CLOSEST TO THE FORECAST AREA. DAYTIME TEMPERATURES WILL
BE A BIT SUPPRESSED UNDER THICK CLOUD COVER...STRONG ONSHORE
WINDS...AND DECENT RAIN COVERAGE.

WEATHER CONDITIONS ARE EXPECTED TO GRADUALLY IMPROVE INTO EARLY
NEXT WEEK AS THE TROPICAL SYSTEM WILL LIKELY 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 MONDAY THROUGH SATURDAY/...
SCATTERED TO NUMEROUS SHOWERS/THUNDERSTORMS WILL CONTINUE TO
DEVELOP LATE THIS AFTERNOON...AND INTO THIS EVENING. WILL KEEP
TSRA MENTIONED IN THE TAFS THROUGH 22Z...WHEN HIGHEST
PROBABILITIES ARE EXPECTED. CAN/T RULE OUT SOME
SHOWER/THUNDERSTORM ACTIVITY LINGERING THROUGH THE EVENING
HOURS...BUT CONFIDENCE IN THIS IS NOT QUITE AS HIGH. AS A
RESULT...WILL CARRY VCSH AT BOTH TERMINALS THROUGH 04Z...AND AMEND
AS DETAILS BECOME MORE APPARENT. ANY LINGERING SHOWERS/STORMS
SHOULD LARGELY BE DONE BY MIDNIGHT...WITH RAIN FREE CONDITIONS
THEN ANTICIPATED THROUGH THE REMAINDER OF THE TAF FORECAST PERIOD.
DEPENDING ON AMOUNTS OF RAIN SEEN AT THE TERMINALS THIS
AFTERNOON...COULD SEE SOME MVFR VSBY/S DEVELOP TOWARD DAYBREAK
TUESDAY AT EITHER TERMINAL...BUT CONFIDENCE IN OCCURRENCE IS TOO
LOW TO MENTION IN THE TAFS AT THIS TIME.

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

&&

.MARINE...
TONIGHT...A COLD FRONT WILL APPROACH FROM THE WEST THIS EVENING
AND PUSH SOUTHWARD THROUGH THE WATERS LATE TONIGHT. NOT
ANTICIPATING MUCH OF A WIND SURGE WITH THE COLD FRONT AS IT WILL
BE IN A WEAKENING STATE AS IT APPROACHES AND MOVES THROUGH. WINDS
AND SEAS ARE EXPECTED TO REMAIN BELOW ADVISORY LEVELS.

TUESDAY THROUGH THURSDAY...THE WEAKENING COLD FRONT WILL DISSIPATE
OVER THE COASTAL WATERS LATE TUESDAY INTO EARLY WEDNESDAY...WHILE
HIGH PRESSURE BUILDS IN FROM THE NORTH. ALTHOUGH THERE COULD BE A
BRIEF NORTHEAST SURGE ON TUESDAY BEHIND THE DESCENDING
FRONT...WINDS AND SEAS ARE EXPECTED TO REMAIN BELOW ADVISORY
CRITERIA THROUGH EARLY WEEK. MODELS CONTINUE TO SUGGEST A COASTAL
TROUGH DEVELOPING BETWEEN HIGH PRESSURE TO THE NORTH AND HURRICANE
IRENE TO THE SOUTH WEDNESDAY INTO EARLY THURSDAY. THIS PATTERN
WOULD MAINTAIN SOLID ONSHORE FLOW AND INCREASE THE POTENTIAL FOR
SCA CRITERIA SEAS BY LATE THURSDAY. SHOWERS AND THUNDERSTORMS WILL
ALSO BE POSSIBLE WHILE ONSHORE FLOW PERSISTS.

HURRICANE IRENE STILL POSES A THREAT TO THE COASTAL WATERS BY LATE
WEEK...ALTHOUGH THERE CONTINUES TO BE SIGNIFICANT UNCERTAINTY IN THE
TRACK FORECAST THIS FAR OUT. CURRENT NHC TRACK SUGGEST HURRICANE
CONDITIONS WILL BE POSSIBLE WITH WAVE TOOLS SUPPORTING SEAS AS HIGH
AS 20-30 FT. MARINERS ARE ADVISED THAT TROPICAL CYCLONE WATCHES
AND/OR WARNINGS COULD BE REQUIRED LATER IN THE WEEK...INCLUDING THIS
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
MID-WEEK...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.
