AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
957 AM EDT MON AUG 22 2011

.SYNOPSIS...
A COLD FRONT WILL APPROACH FROM THE NORTHWEST TODAY. THE FRONT
WILL STALL OVER THE AREA TONIGHT AND TUESDAY...THEN DISSIPATE
WEDNESDAY AS HIGH PRESSURE BUILDS FROM THE NORTH. HURRICANE IRENE
COULD IMPACT THE AREA LATE IN THE WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
CURRENTLY AT THE SURFACE...A COLD FRONT EXTENDS FROM CENTRAL
NORTH CAROLINA SOUTHWESTWARD INTO CENTRAL GEORGIA. SHOWERS FROM
EARLIER THIS MORNING HAVE DISSIPATED OVER LAND AREAS...WITH
GENERALLY CLEAR TO PARTLY CLOUDY SKIES IN PLACE AS EVIDENT IN
SATELLITE IMAGERY. MAIN NEAR TERM CONCERN REVOLVES AROUND SEVERE
POTENTIAL THIS AFTERNOON.

A SHORTWAVE TROUGH EVIDENT IN WATER VAPOR IMAGERY OVER THE SOUTH
CAROLINA UPSTATE AND NORTHERN GEORGIA THIS MORNING WILL CONTINUE
TO PUSH SOUTHEASTWARD TOWARD AND INTO THE FORECAST AREA THIS
AFTERNOON. UPPER LEVEL FORCING FOR ASCENT WITH THIS FEATURE ALONG
WITH SOME EXIT REGION FORCING FROM A 70+ KNOT H25 JET AND THE
AFTERNOON SEA BREEZE SHOULD BE SUFFICIENT FOR SCATTERED TO NUMEROUS
SHOWER AND THUNDERSTORM DEVELOPMENT. ADJUSTING THE KCHS 12Z
SOUNDING YIELDS IMPRESSIVE SURFACE BASED CAPE VALUES OF 3500-4000
J/KG AND LI/S OF -7 TO -8. WITH A SUBSTANTIAL MID-LEVEL DRY AIR
NOTED IN THE SOUNDING...AND DCAPE VALUES PROGGED AROUND 1200
J/KG...DAMAGING WINDS REMAIN A CONCERN WITH THE STRONGER STORMS
THAT DEVELOP. WILL CONTINUE TO MENTION THE POTENTIAL FOR SEVERE
WEATHER IN THE HAZARDOUS WEATHER OUTLOOK AS WELL AS OTHER FORECAST
PRODUCTS.

TEMPERATURES APPEAR ON TRACK TO TOP OUT GENERALLY IN THE MID 90S
AWAY FROM THE COAST.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY/...
TONIGHT...TSTMS WILL GRADUALLY DIMINISH DURING THE EVENING HOURS
AS THE ATMOSPHERE GET STEADILY OVERTURNED IN THE WAKE OF
CONVECTION. THERE REMAINS MUCH UNCERTAINLY ON HOW QUICKLY
CONVECTION WILL DIE OFF...ESPECIALLY IF ACTIVITY IN THE COASTAL
CORRIDOR BECOMES ORGANIZED AND PUSHES OFFSHORE SOONER THAN
EXPECTED. WILL GO WITH 40-60 PERCENT POPS FOR THE EARLY EVENING
HOURS...HIGHEST ALONG THE COASTAL COUNTIES...BUT THESE WILL MOST
CERTAINLY BE ADJUSTED AS TRENDS BECOME MORE APPARENT LATER TODAY.
LOWS WILL RANGE FROM THE LOWER 70S INLAND TO THE UPPER 70S AT THE
COAST...ALTHOUGH LOCALLY LOWER VALUES WILL BE POSSIBLE WHERE
EVENING TSTMS OCCUR. A FEW UPPER 60S WILL BE POSSIBLE ACROSS THE
FAR INTERIOR AREAS... ESPECIALLY IF THE APPROACHING COLD FRONT AND
ASSOCIATED LOWER DEWPOINTS MEANDER INTO THE WESTERN AND CENTRAL
PORTIONS OF THE FORECAST AREA AS SUGGESTED BY THE 22/00Z NAM AND
GFS.

TUESDAY...THE WEAKENING COLD FRONT WILL CONTINUE TO DRIFT
SOUTHWARD OVER THE FORECAST AREA ON TUESDAY...AS HIGH PRESSURE
BUILDS TO THE NORTH. AT THE SAME TIME...THE TROUGH ALOFT WILL
DISSIPATE ACROSS THE SOUTHEAST COAST AND CREATE A WEAKNESS IN THE
UPPER LEVEL PATTERN INTO THE MID WEEK PERIOD. SURFACE WINDS WILL
BE SOLIDLY ONSHORE BY THE AFTERNOON HOURS. DESPITE DRIER DEEP
LAYER AIR INTRUDING FROM THE NORTH/NORTHWEST...THIS ONSHORE FLOW
SHOULD MAINTAIN SUFFICIENT MOISTURE IN AT LEAST THE LOW LEVELS TO
SPAWN ISOLATED TO SCATTERED DIURNAL CONVECTION. THE MAIN FOCUS
WILL LIKELY BE THE SEABREEZE AND ANY BOUNDARY INTERACTIONS.

THE SURFACE HIGH WILL SLIP INTO THE ATLANTIC TUESDAY NIGHT...WITH
A COASTAL TROUGH DEVELOPING ALONG ITS SOUTHERN PERIPHERY. ENHANCED
MOISTURE AND CONVERGENCE COULD MAINTAIN ISOLATED SHOWERS/THUNDERSTORM
OVER THE MARINE ZONES AND LOCALLY ONSHORE INTO THE EARLY MORNING
HOURS ON WEDNESDAY.

WEDNESDAY...HURRICANE IRENE WILL BE STEADILY PROGRESSING THROUGH THE
BAHAMAS ON WEDNESDAY...LIKELY ENHANCING THE COASTAL TROUGH ACROSS
THE LOCAL WATERS TO THE NORTH OF THE SYSTEM. NUMERICAL MODELS
INDICATE A SWATH OF DEEP MOISTURE PUSHING THROUGH THE MARINE ZONES
AND LOCALLY ONSHORE THROUGH THE DAY AND INTO THE EVENING HOURS. THE
CONTINUED ONSHORE FLOW...COMBINED WITH CONVERGENCE ASSOCIATED WITH
THE COASTAL TROUGH...IS EXPECTED TO SUPPORT RAIN CHANCES IN THE 30
PERCENT RANGE ON WEDNESDAY. BEST PRECIPITATION POTENTIAL WILL ONCE
AGAIN SHIFT TOWARD THE COAST AND OFFSHORE WEDNESDAY NIGHT...AS
DIURNAL HEATING AND INSTABILITY WANE OVER LAND AREAS.

THURSDAY...A LARGE AMOUNT OF UNCERTAINTY IS INTRODUCED INTO THE
FORECAST BY THURSDAY...AS MODELS HAVE BEEN CONSISTENTLY
INDICATING IRENE WILL MAINTAIN A NORTH/NORTHWEST TRACK TOWARD THE
FLORIDA PENINSULA AND/OR SOUTHEAST COASTLINE. THE SYSTEM WILL
STILL LIKELY BE SOUTH OF THE FORECAST AREA ON THURSDAY...AND THUS
CONVECTION COULD BE CONTROLLED MAINLY BY THE PINCHED COASTAL
TROUGH. PREFER TO KEEP SHOWER/THUNDERSTORM POTENTIAL IN THE 30
PERCENT RANGE AGAIN FOR THE DAYTIME HOURS ON THURSDAY...HIGHEST
ACROSS SOUTHERN PORTIONS CLOSEST TO DEEP MOISTURE FROM THE
TROPICAL SYSTEM. HAVE ALSO INDICATED STEADILY INCREASING SKY COVER
BY MID TO LATE WEEK WITH THE APPROACHING SYSTEM.

PERSISTENT ONSHORE FLOW AND STEADILY INCREASING CLOUD COVER WILL
ALLOW A SLIGHT COOLING TREND THROUGH THE SHORT TERM PERIOD. HIGHS
COULD BE A DEGREE OR TWO BELOW SEASONAL NORMALS WEDNESDAY AND
THURSDAY.

&&

.LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/...
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
FLORIDA AND/OR SOUTHEAST COAST...THERE REMAINS CONSIDERABLE
UNCERTAINTY REGARDING THE EVOLUTION OF THIS SYSTEM.

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 /14Z MONDAY THROUGH FRIDAY/...
SCATTERED-NUMEROUS TSTMS ARE EXPECTED THIS AFTERNOON AHEAD OF A
COLD FRONT. THESE WILL LIKELY IMPACT THE TERMINALS BUT THE TIMING
REMAINS IN QUESTION. WILL INTRODUCE A TEMPO GROUP FOR MVFR
CONDITIONS IN TSRA FROM ROUGHLY 20-00Z TO TREND.

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

&&

.MARINE...
A MODEST LATE SUMMER NOCTURNAL SURGE IS IN PROGRESS ACROSS THE
WATERS EARLY THIS MORNING WITH WINDS GENERALLY 15-20 KT NEARSHORE
WITH A SOLID 20 KT OVER THE GEORGIA OFFSHORE LEG. WINDS WILL
DIMINISH AS SUNRISE APPROACHES AND THE NOCTURNAL JET BEGINS TO
BREAK DOWN.

A SOUTHERLY WIND REGIME WILL PREVAIL THROUGH TONIGHT WITH THE
REGION REMAINING ALONG THE WESTERN FRINGES OF ATLANTIC HIGH
PRESSURE. WINDS WILL GENERALLY REMAIN 15 KT OR LESS THROUGH
TONIGHT...ALTHOUGH THE WIND FIELD COULD BECOME QUITE CHAOTIC
TONIGHT AS TSTMS MOVE OFFSHORE WITH THE POTENTIAL FOR A LARGE
OUTFLOW BOUNDARY MOVING ACROSS THE ENTIRE MARINE AREA. MARINERS
ARE URGED TO REMAIN ALERT THIS AFTERNOON AND EVENING FOR STRONG
TO SEVERE TSTMS. SPECIAL MARINE WARNINGS ARE LIKELY.

THE WEAKENING FRONT WILL SETTLE OVER THE MARINE ZONES BY
TUESDAY...DISSIPATING ACROSS THE AREA AS HIGH PRESSURE BUILDS TO
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 ARE
SUGGESTING A COASTAL TROUGH COULD DEVELOP BETWEEN HIGH PRESSURE TO
THE NORTH AND HURRICANE IRENE TO THE SOUTH BY LATE TUESDAY INTO
EARLY THURSDAY. THIS PATTERN WOULD MAINTAIN SOLID ONSHORE FLOW AND
INCREASE THE POTENTIAL FOR SHOWER ACTIVITY OVER THE WATERS.

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. 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.

&&

.EQUIPMENT...
WFO CHARLESTON WILL BE RELEASING 6-HOURLY UPPER AIR SOUNDINGS
UNTIL FURTHER NOTICE IN SUPPORT OF HURRICANE IRENE.

&&

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