AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
404 PM EDT THU JUL 31 2008

.SYNOPSIS...
ATLANTIC HIGH PRESSURE WILL REMAIN OFFSHORE THROUGH EARLY NEXT
WEEK...WHILE A WEAK SURFACE TROUGH LINGERS ACROSS INLAND AREAS.
UPPER LEVEL HIGH PRESSURE WILL BE STRENGTHENING NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
WATER VAPOR IMAGERY SHOWS THE UPPER LEVEL SHORTWAVE MOVING INTO THE
EASTERN OHIO AND TENNESSEE VALLEYS THIS AFTERNOON...WHILE RIDGING
ALOFT PERSISTS ACROSS THE SOUTHERN STATES. DESPITE THE CONTINUED
ADVECTION OF DEEP MOISTURE FROM THE GULF OF MEXICO INTO SOUTHERN
GEORGIA...LITTLE CONVECTION HAS INITIATED THIS HOUR AS THE
ATMOSPHERE REMAINS CAPPED AND THE SEABREEZE IS PINNED ALONG THE
COASTLINE. WITH THE DELAY OF THE SEABREEZE PROGRESSION...EXPECT
THUNDERSTORM COVERAGE TO REMAIN SPARSE FOR THE NEXT FEW HOURS.
ONCE THE SEABREEZE BEGINS MOVEMENT AWAY FROM THE SHORE...SHOWERS
AND THUNDERSTORMS WILL BECOME SCATTERED ACROSS SOUTHEAST SOUTH
CAROLINA AND GEORGIA. ALTHOUGH CONDITIONS HAVE DELAYED MORE
WIDESPREAD DEVELOPMENT OVER THE FORECAST AREA...STRONGER
CONVECTION HAS INITIATED JUST TO THE WEST WITHIN THE INLAND TROUGH
AND WEAKER UPPER LEVEL ENERGY AHEAD OF THE MAIN SHORTWAVE. THESE
THUNDERSTORMS WILL CONTINUE TO PUSH INTO THE FAR INLAND SOUTH
CAROLINA COUNTIES WITHIN THE HOUR.

WILL MAINTAIN 30 TO 40 PERCENT POPS ACROSS SOUTH CAROLINA AND UP
TO 60 PERCENT CHANCE SOUTH OF I-16 IN SOUTHEAST GEORGIA.
INSTABILITY HAS INCREASED AS EXPECTED...WITH CAPE VALUES BETWEEN
3000 AND 4000 J/KG AND LIFTED INDICES DOWN TO -5 TO -6. ANY
THUNDERSTORMS WILL BE ABLE TO PRODUCE HEAVY RAIN...LOCALIZED
FLOODING...FREQUENT LIGHTNING AND GUSTY WINDS. SPC CONTINUES TO
PLACE THE INLAND SOUTH CAROLINA COUNTIES IN A SLIGHT RISK ZONE FOR
SEVERE THUNDERSTORMS...SO WILL KEEP MENTION OF ISOLATED SEVERE
STORMS IN THE HAZARDOUS WEATHER OUTLOOK.

WILL INDICATE A DECREASING TREND IN POPS OVERNIGHT...WITH THE
LOSS OF DAYTIME INSTABILITY AND SEABREEZE FORCING. HOWEVER...UPPER
LEVEL SHORTWAVE WILL MAKE ITS CLOSEST APPROACH TO THE FORECAST
AREA OVERNIGHT. CONSIDERING LINGERING MESOSCALE BOUNDARIES FROM
EARLIER CONVECTION...AS WELL AS SOME SYNOPTIC SCALE FORCING FROM
THE SHORTWAVE...WILL MAINTAIN POPS THROUGH THE NIGHT. HAVE
INDICATED HIGHER POPS AROUND 30 PERCENT FOR THE SOUTH CAROLINA
ZONES THROUGH FRIDAY MORNING...CLOSEST TO THE SHORTWAVE ENERGY
PASSING TO THE NORTH...WHILE DECREASING POPS IN THE GEORGIA ZONES
TO SLIGHT CHANCE AFTER MIDNIGHT.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH 6 PM FRIDAY/...
UPPER LEVEL TROUGH WILL AMPLIFY OVER THE SOUTHEAST ON
FRIDAY...WHILE WEAK SHORTWAVE ENERGY CONTINUES TO DRIFT INTO THE
REGION. BOTH GFS AND NAM SUGGEST THAT DEEPEST MOISTURE WILL BE
PUSHED SOUTH AND EAST...AS THE INLAND SURFACE TROUGH NUDGES TOWARD
THE COASTLINE AND DRIER AIR PUSHES IN FROM THE NORTHWEST. HAVE
INDICATED CHANCE POPS ACROSS THE FORECAST AREA...AS TYPICAL
SUMMERTIME INSTABILITY AND SEABREEZE FORCING SHOULD STILL BE ABLE
TO INITIATE SCATTERED SHOWERS AND THUNDERSTORMS DURING THE
AFTERNOON AND EARLY EVENING. STILL SOME UNCERTAINTY ABOUT THE
DEGREE OF COVERAGE CONSIDERING THE DRY AIR INTRUSION FROM THE
NORTH...YET WILL STICK WITH CLIMATOLOGY AT THIS POINT AND CONTINUE
MENTION OF DIURNAL CONVECTION. POP SCHEME INCLUDES 30 PERCENT POPS
ACROSS SOUTH CAROLINA ZONES...INCREASING TO 40 TO 50 POPS SOUTH OF
SAVANNAH RIVER CLOSER TO DEEPEST MOISTURE ACCESS.

THE COMBINATION OF HIGH TEMPERATURES BETWEEN 93 AND 96 DEGREES
AWAY FROM THE COAST...AND DEWPOINTS IN THE MID 70S...WILL LEAD TO
HEAT INDICES FROM 103 TO 106 DEGREES. A HEAT ADVISORY WILL LIKELY
BE NEEDED FOR FRIDAY...BUT WOULD PREFER TO HOLD OFF ISSUANCE AT
THIS POINT.

&&

.LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/...
GUIDANCE IS IN GENERALLY GOOD AGREEMENT THROUGH SATURDAY
NIGHT...WITH SOLUTIONS THEN DIVERGING A BIT SUNDAY THROUGH THE
MIDDLE OF THE UPCOMING WORK WEEK.

THE SURFACE PRESSURE PATTERN WILL CHANGE LITTLE DURING THE FRIDAY
NIGHT THROUGH SATURDAY NIGHT TIME FRAME...WITH A TROUGH OF LOW
PRESSURE REMAINING NORTH OF THE FORECAST AREA AND ATLANTIC HIGH
PRESSURE REMAINING WELL TO THE SOUTHEAST OF THE REGION. EXPECT ANY
LINGERING SHOWER AND THUNDERSTORM ACTIVITY TO END QUICKLY FRIDAY
EVENING...WITH CONDITIONS THEN REMAINING DRY THROUGH THE OVERNIGHT
HOURS. WILL CONTINUE SLIGHT CHANCE/LOW CHANCE POPS ACROSS THE AREA
SATURDAY...WITH BEST CHANCES EXPECTED NEAR THE COAST AND ACROSS THE
SOUTHERN 2/3RDS OF THE CWA. BOTH THE NAM AND GFS SHOW A FAIRLY
VIGOROUS SHORTWAVE TROUGH APPROACHING NORTHERN AREAS LATE SATURDAY
AFTERNOON AND EVENING...SO WILL CARRY CHANCE POPS ALL AREAS IN THE
EVENING...THEN TRANSITION TO SLIGHT CHANCE POPS OVERNIGHT.

THE FORECAST BECOMES A BIT MORE UNCERTAIN BEGINNING SUNDAY...AS THE
GFS SPINS UP A WEAK AREA OF LOW PRESSURE OVER THE GULF COAST STATES
AND RETROGRADES THE SYSTEM INTO THE LOWER MISSISSIPPI VALLEY AND
SOUTHERN PLAINS BY THE MIDDLE OF NEXT WEEK. THE NAM/ECMWF/UKMET ON
THE OTHERHAND DON/T DEVELOP A LOW...AND INSTEAD CONTINUE TO KEEP A
PERSISTENT TROUGH NORTH AND WEST OF THE AREA...WITH ATLANTIC HIGH
PRESSURE REMAINING WELL SOUTHEAST OF THE CWA. WILL GENERALLY FOLLOW
THE CONSENSUS SOLUTION FOR NOW AND RUN WITH SLIGHT CHANCE/LOW CHANCE
POPS SUNDAY THROUGH THURSDAY FOR AFTERNOON/EVENING CONVECTION. IF
THE GFS SOLUTION DOES INDEED PAN OUT...WE MAY NEED TO INCREASE POPS
DURING THIS TIME FRAME AS ONSHORE FLOW WOULD LIKELY RESULT IN
INCREASED SHOWER/THUNDERSTORM COVERAGE.

TEMPERATURES THROUGHOUT THE EXTENDED PERIOD ARE EXPECTED TO RUN
SEVERAL DEGREES ABOVE CLIMO. IF THE GFS SOLUTION IS CORRECT...WE MAY
BE A COUPLE DEGREES TOO WARM...AND A COUPLE DEGREES TOO COOL IF THE
ECMWF SOLUTION ENDS UP PANNING OUT.

&&

.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
TEMPO MVFR CONDITIONS ARE POSSIBLE FOR CHS THIS AFTERNOON WITH THE
DEVELOPMENT OF THUNDERSTORMS OVER THE AREA. HAVE INTRODUCED TEMPO
-TSRA FROM 20Z TO 23Z AS SHOWERS AND THUNDERSTORMS ARE DEVELOPING
UPSTREAM OF CHS AIRPORT. TEMPO -TSRA FROM 18Z TO 22Z WILL REMAIN
IN THE FORECAST FOR THE SAV TERMINAL AS WELL. SOUTHWEST WINDS
AROUND 10 KNOTS WILL PERSIST AT BOTH TERMINALS THROUGHOUT THE DAY.
COULD SEE A FEW GUSTS OVER THE CHS AIRPORT THIS AFTERNOON WITH THE
ARRIVAL OF A SEABREEZE.

SHOWERS AND THUNDERSTORMS WILL QUICKLY DISSIPATE THIS EVENING WITH
DAYTIME HEAT LOSS. WINDS WILL REMAIN SOUTHWEST AT OR BELOW 10
KNOTS THROUGH THE NIGHT. SCT CLOUDS WILL REMAIN THROUGH THE NIGHT
AT BOTH TERMINALS. WINDS WILL BECOME WEST NORTHWEST BY LATE
TOMORROW MORNING.

EXTENDED AVIATION OUTLOOK...THE BEST CHANCE FOR AFTERNOON SHOWERS AND
THUNDERSTORMS LOOK TO BE FOR FRIDAY...WITH MVFR CONDITIONS POSSIBLE
WITHIN ANY THUNDERSTORMS. LOW END CHANCES FOR AFTERNOON SHOWERS AND
THUNDERSTORMS EXPECTED SATURDAY THROUGH WEDNESDAY WITH AGAIN MVFR
CONDITIONS POSSIBLE WITHIN ANY THUNDERSTORMS.

&&

.MARINE...
A SHORT WAVE WILL APPROACH THE REGION FROM THE NORTHEAST
TONIGHT...WHILE THE INLAND SURFACE TROUGH STRENGTHENS AND SHIFTS
CLOSER TO THE COASTLINE. AS A RESULT...THE PRESSURE GRADIENT WILL
CONTINUE TO TIGHTEN AND ENHANCE SOUTHWEST SURFACE FLOW OVER THE
MARINE ZONES. TYPICAL LATE DAY AND NOCTURNAL SURGING SHOULD BE
ENHANCED ENOUGH TO REACH A PERIOD OF SMALL CRAFT ADVISORY
CONDITIONS FROM LATE THIS AFTERNOON THROUGH THE OVERNIGHT
HOURS...WITH WINDS 20 TO 25 KT. WILL MAINTAIN SCA AS IS TO ACCOUNT
FOR THE FAVORABLE TIMING OF THE ENHANCED LOW LEVEL WIND FIELDS AND
LOW LEVEL JET. SOUTHWEST WINDS WILL DROP BELOW ADVISORY LEVELS ON
FRIDAY.

SURFACE PRESSURE PATTERN WILL CHANGE LITTLE FRIDAY NIGHT THROUGH
WEDNESDAY...WITH A TROUGH REMAINING TO THE NORTHWEST OF THE
WATERS...AND ATLANTIC HIGH PRESSURE RESIDING WELL TO THE SOUTHEAST
OF THE REGION. THIS WILL RESULT IN A SOUTHERLY FLOW ACROSS THE
WATERS THROUGH THE PERIOD. EXPECT DECENT SURGES AS GRADIENT PINCHES
PRETTY GOOD FRIDAY NIGHT AND SATURDAY NIGHT...WITH GRADIENT RELAXING
IN RESULTING IN LESS INTENSE NOCTURNAL SURGING SUNDAY NIGHT THROUGH
WEDNESDAY. WINDS AND SEAS ARE EXPECTED TO REMAIN BELOW HEADLINE
THRESHOLDS FRIDAY NIGHT THROUGH WEDNESDAY.

&&

.CHS WATCHES/WARNINGS/ADVISORIES...
GA...NONE.
SC...NONE.
MARINE...SMALL CRAFT ADVISORY UNTIL 5 AM EDT FRIDAY FOR AMZ350-352-354-
