AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE CHARLESTON SC
400 PM EDT THU AUG 4 2011

...EXCESSIVE HEAT TO CONTINUE...

.SYNOPSIS...
A SURFACE TROUGH OF LOW PRESSURE WILL PERSIST INLAND THROUGH THE
WEEKEND. A COLD FRONT MAY APPROACH FROM THE NORTHWEST DURING THE
EARLY AND MIDDLE PART OF NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
DANGEROUSLY HOT CONDITIONS ARE IN PROGRESS ACROSS THE REGION WITH
THE MOST EXTREME HEAT OCCURRING FROM THE SAVANNAH METRO AREA
THROUGH BEAUFORT INTO THE CHARLESTON TRI-COUNTY AREA WHERE HEAT
INDICES ARE RUNNING 115-120 DEGREES. ALL HEAT RELATED WARNINGS
AND ADVISORIES WILL REMAIN IN FORCE THROUGH 8 PM...ALTHOUGH PARTS
MAY BE CANCELLED EARLY DEPENDING ON HOW TSTMS EVOLVE OVER THE
NEXT FEW HOURS.

SOME PRELIMINARY MAX HEAT INDICES AS OF 04/19Z...120 AT EAST
COOPER AIRPORT /LRO/...117 AT CHARLESTON EXECUTIVE AIRPORT
/JZI/...116 AT THE CHARLESTON AIRPORT /CHS/...116 AT HILTON HEAD
AIRPORT AND 114 AT HUNTER ARMY AIRFIELD /SVN/.

CONVECTIVE INITIATION IS ONGOING. ACTIVITY APPEARS TO BE ORGANIZING
ALONG TWO FEATURES. THE FIRST IS A RESIDUAL OUTFLOW BOUNDARY WHICH
STRETCHES FROM SOUTH-CENTRAL GEORGIA TO NEAR THE SAVANNAH AREA WITH
THE SECOND ALONG THE LEE-SIDE THROUGH EXTENDING FROM CENTRAL GEORGIA
THROUGH THE CSRA INTO THE SOUTH CAROLINA MIDLANDS. EXTREME
INSTABILITY IS IN PLACE WITH SBCAPES EXCEEDING 5000 J/KG IN PLACES
AND LI/S CLOSE TO -9C. HOWEVER...VISIBLE SATELLITE DATA SUGGEST
CAPPING IS STILL PREVALENT WITH LITTLE IF ANY VERTICAL DEVELOPMENT
NOTED IN THE CUMULUS FIELD OUTSIDE OF THE ABOVE MENTIONED FEATURES.
THIS SHOULD CHANGE SHORTLY AS CONVECTIVE TEMPERATURES ARE BREACHED
AND SHORTWAVE ENERGY UPSTREAM DRAWS CLOSER. WILL GO WITH A 20/50
PERCENT POP REGIME INTO THE EARLY EVENING HOURS WITH THE BULK OF THE
HIGH RESOLUTION GUIDANCE FAVORING THE GREATEST COVERAGE ALONG/SOUTH
OF I-16 IN THE VICINITY OF THE RESIDUAL OUTFLOW BOUNDARY. THIS SEEMS
REASONABLE GIVEN HOW RADAR AND MESOSCALE TRENDS ARE SETTING UP.

ISOLATED SEVERE TSTMS WILL BE POSSIBLE THROUGH LATE EVENING.
THE SPECIAL 04/18Z CHS RAOB SHOWS DCAPES IN EXCESS OF 1300 J/KG
WITH A DELTA EPT/S NEAR 42C. THIS IS QUITE IMPRESSIVE FOR THE PEAK
OF SUMMER. PRIMARY HAZARD WILL BE DAMAGING WINDS...ALTHOUGH A
HCAPES OF 1300 J/KG COULD SUPPORT A MARGINALLY SEVERE HAIL REPORT
IN THE MOST INTENSE STORMS. WEAK SHEAR SUPPORTS MORE OF A PULSE
CONVECTIVE MODE WITH SHORT DURATION ORGANIZATION POSSIBLE ALONG
MESOSCALE BOUNDARY COLLISIONS.

CONVECTION WILL GRADUALLY DIE OFF OVERNIGHT. LOWS WILL RANGE FROM
THE MID 70S FAR INLAND TO THE LOWER 80S AT THE COAST.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH SUNDAY/...
THE FORECAST AREA WILL REMAIN WITHIN A WEAKNESS IN THE UPPER RIDGE
CURRENTLY STRETCHING ACROSS THE SOUTHERN UNITED STATES AND INTO THE
ATLANTIC. A SERIES OF SHORTWAVES WILL THUS BE ABLE TO IMPACT THE
SOUTHEAST STATES AND MAINTAIN A SWATH OF DEEP MOISTURE OVER THE
REGION. AT THE SURFACE...A TROUGH OF LOW PRESSURE AND ASSOCIATED
FRONT WILL LINGER ACROSS THE REGION AND PROVIDE AN ADDITIONAL FOCUS
FOR CONVECTIVE DEVELOPMENT WITH THE TYPICAL SEABREEZE BOUNDARY.

WEAKENING SUBSIDENCE...DEEP LAYER MOISTURE FROM UPPER LEVEL
ENERGY...AND FORCING FROM THE SURFACE TROUGH WILL COMBINE TO
SUPPORT IMPROVED THUNDERSTORM CHANCES FRIDAY THROUGH SUNDAY. HAVE
INDICATED POPS IN THE SOLID CHANCE RANGE OF 30 TO 40 PERCENT EACH
DAY ACCORDINGLY. HIGHEST CONFIDENCE IN THUNDERSTORM COVERAGE AT
THIS POINT IS ON SATURDAY...WHEN GFS AND NAM SHOW THE STRONGEST
SHORTWAVE SLIPPING EAST TOWARD THE FORECAST AREA. HAVE MAINTAINED
SOME MENTION OF RAIN POTENTIAL DURING THE OVERNIGHT HOURS DESPITE
WANING DIURNAL INSTABILITY AND HEATING...AS LARGE SCALE SUPPORT
FROM SHORTWAVE ENERGY AND SURFACE FEATURES COULD ALLOW ISOLATED
CONVECTION TO CONTINUE.

HIGH TEMPERATURES ON FRIDAY WILL REACH THE UPPER 90S AWAY FROM THE
LOCALLY COOLER COAST. DEWPOINTS ARE EXPECTED TO REMAIN IN THE MID
TO UPPER 70S DURING THE AFTERNOON HOURS...SUPPORTING HEAT INDICES
PEAKING AROUND 110 DEGREES ACROSS THE FORECAST AREA. ALTHOUGH
THERE IS SOME UNCERTAINTY REGARDING THE IMPACTS OF INCREASING SKY
COVER AND RAIN COVERAGE ON FRIDAY...LATEST THINKING IS THAT MOST
LOCATIONS WILL STILL REACH AT LEAST 105 DEGREE INDICES. HAVE THUS
ISSUED A HEAT ADVISORY BEGINNING AT NOON ON FRIDAY.

ALTHOUGH HIGH TEMPERATURES ON SATURDAY AND SUNDAY COULD TREND A
FEW DEGREES COOLER...ABUNDANT LOW LEVEL MOISTURE AND DAYTIME
DEWPOINTS IN THE UPPER 70S COULD MAINTAIN AT LEAST MARGINAL HEAT
ADVISORY CONDITIONS BOTH DAYS. HOWEVER...SCATTERED CONVECTION AND
THICKER CLOUD COVER COULD STILL CREATE A DIFFICULT TEMPERATURE
FORECAST.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
A BROAD TROUGH WILL DEVELOP ALOFT OVER THE EAST AND SOUTHEAST STATES
DURING THE EARLY TO MIDDLE PART OF NEXT WEEK...AS A COLD FRONT
ATTEMPTS TO APPROACH FROM THE NORTHWEST. THE FRONT WILL MOST LIKELY
RUN OUT OF STEAM AS IT BECOMES PARALLEL TO THE WEST AND WEST-NW
FLOW ALOFT...SO A CONTINUATION OF ABOVE NORMAL TEMPERATURES WILL
AGAIN PREVAIL. RAIN CHANCES WILL FALL AS THE DRIER FLOW ALOFT
ALLOWS FOR SOME DECREASE IN DEEP LAYERED MOISTURE. WILL DROP
PROBABILITIES TO 30 PERCENT MONDAY...AND TO 20 PERCENT TUESDAY
THROUGH THURSDAY. 850 MB TEMPS ARE NEAR 20-21C...SO TEMPS WILL
REMAIN ABOVE SEASONAL NORMALS.

&&

.AVIATION /20Z THURSDAY THROUGH TUESDAY/...
WHILE VFR WEATHER WILL PREVAIL AT BOTH TERMINALS THROUGH 12Z
FRIDAY...THERE IS THE RISK OF A COUPLE OF HOURS OF MVFR CONDITIONS
IN CONVECTION LATE TODAY AND TONIGHT. FOR THAT REASON WE HAVE
CARRIED CB CLOUDS FROM 20Z-01Z AT KCHS AND FROM 20Z-03Z AT KSAV.
PROBABILITIES ARE HIGHER AT KSAV WHERE A MOISTURE AXIS WILL ALIGN
ITSELF LATER TODAY AND WHERE BEST BOUNDARY INTERACTION WILL OCCUR.
THUS WE SUSPECT THAT LATER TAF ISSUANCES WILL INDICATE A BETTER
RISK OF TSRA AT THAT TERMINAL. SW WINDS OF 8-12 KT WILL BACK
AROUND TO SOUTH WITH THE SEA BREEZE LATE THIS AFTERNOON/EVENING AS
SPEEDS INCREASE INTO THE LOWER-MID TEENS. SHOULD ANY TSRA IMPACT
THE TERMINALS...GUSTY WINDS ARE POSSIBLE.

EXTENDED AVIATION OUTLOOK...THERE ARE NO SIGNIFICANT CONCERNS ATTM
WITH A GREATER THAN 30 PERCENT CONFIDENCE.

&&

.MARINE...
ANOTHER MODEST NOCTURNAL SURGE IS EXPECTED TONIGHT WITH WINDS
GENERALLY 15-20 KT EXPECT 20 KT OVER THE CHARLESTON COUNTY
COASTAL WATERS. THE UNDERLYING 8-10 SECOND BACK SWELL GENERATED BY
LOW PRESSURE OFF THE MID-ATLANTIC WILL DIMINISH TONIGHT WITH
COMBINED SEAS OF 2-4 FT EXPECTED.

THE COASTAL WATERS WILL REMAIN BETWEEN AN INLAND TROUGH OF LOW
PRESSURE AND THE SUB-TROPICAL ATLANTIC RIDGE FRIDAY THROUGH
SATURDAY...BEFORE THE SURFACE TROUGH AND ASSOCIATED BOUNDARY SHIFT
CLOSER TO THE COASTLINE ON SUNDAY.

WIND DIRECTIONS WILL BE SOUTHERLY FRIDAY THROUGH SATURDAY...THEN
VEER MORE SOUTHWEST SUNDAY INTO EARLY NEXT WEEK. SPEEDS WILL
GENERALLY HOLD AT 15 KT OR LESS...ALTHOUGH SEA BREEZE CIRCULATION
AND NOCTURNAL LOW LEVEL JETTING WILL OCCASIONALLY INCREASE WINDS TO
15 TO 20 KT AT TIMES. LONGER PERIOD SWELLS COULD BEGIN IMPACTING THE
COASTAL WATERS THIS WEEKEND INTO EARLY NEXT WEEK. THIS COULD ALLOW
FOR SEAS TO REACH AS HIGH AS 5 OR 6 FT SATURDAY NIGHT THROUGH EARLY
MONDAY ACROSS THE OUTER WATERS.

RIP CURRENTS...LONGER PERIOD SWELLS COULD IMPACT THE BEACHES LATE
THIS WEEKEND INTO EARLY NEXT WEEK. THIS COULD RESULT IN AN ENHANCED
RISK OF RIP CURRENTS.
