AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
1003 AM EDT SUN JUL 31 2011

.SYNOPSIS...
A TROUGH OF LOW PRESSURE WILL PERSIST AT THE SURFACE
MUCH OF THE WEEK WHILE UPPER HIGH PRESSURE MOVES IN FROM THE WEST
LATE IN THE WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
31/12Z UPPER AIR PLOTS AND MORNING WATER VAPOR IMAGERY CONFIRMS
THE UPPER RIDGE HAS RETROGRADED TO THE WEST LEAVING MUCH OF THE
SOUTHEAST U.S. IN A BROAD WEAKNESS WITH A STIFF NORTHWEST FLOW
ALOFT. 31/13Z SURFACE ANALYSIS PLACED A PRONOUNCED SURFACE TROUGH
ROUGHLY ALONG A SUMTER-WALTERBORO-SAVANNAH-JESUP LINE WITH WEAK
LOW PRESSURE NOTED BETWEEN ORANGEBURG AND SUMTER. THIS TROUGH
COUPLED WITH THE SEA BREEZE...THE VARIOUS LAKE BREEZE CIRCULATIONS
AROUND THE SANTEE LAKES AND RESIDUAL CONVECTIVE OUTFLOWS FROM
TSTMS SATURDAY AFTERNOON WILL SERVE AS THE PRIMARY FOCI FOR
CONVECTIVE DEVELOPMENT THIS AFTERNOON.

RUC VORTICITY FIELDS SUGGESTS A VORT LOBE CURRENTLY MEANDER
SOUTHEAST ACROSS THE NORTH CAROLINA COASTAL PLAIN INTO THE SOUTH
CAROLINA MIDLANDS WILL SINK SLOWLY SOUTHEAST TODAY...REACHING
SOUTH COASTAL SOUTH CAROLINA AND NORTH COASTAL GEORGIA DURING PEAK
HEATING. THIS COUPLED WITH STRONG ATMOSPHERE INSTABILITY WILL
SUPPORT SCATTERED SHOWERS AND TSTMS. HIGH RESOLUTION GUIDANCE
SUPPORTS OUR CURRENT 50 PERCENT POP REGIME AWAY FROM THE COAST
THIS AFTERNOON AND VERY FEW CHANGES TO THIS WILL BE MAKE WITH THE
LATE MORNING UPDATE. ONCE TSTMS INITIATE...CONVECTIVE COVERAGE
WILL ULTIMATELY BE DETERMINED BY MESOSCALE PROCESSES SUCH AS
BOUNDARY COLLISIONS. WILL LIKELY HAVE TO MAKE ADDITIONAL
MODIFICATIONS TO THE POP FORECAST AS THE AFTERNOON PROGRESSES.

THE 12Z MODIFIED CHS RAOB INDICATES THE ATMOSPHERE WILL BECOME
STRONGLY UNSTABLE AFTER 18Z WITH SBCAPES REACHING IN EXCESS OF
4000 J/KG WITH LI/S AS LOW AS -7 TO -9C. DCAPES ARE FORECAST TO
RISE TO NEAR 1400 J/KG WHICH COUPLED WITH DELTA SFC-700MB EPTS
NEAR 37C WILL SUPPORT A RISK FOR DAMAGING WINDS WITH THE STRONGER
TSTMS. 0-6KM BULK SHEAR IS FORECAST TO REMAIN 15 KT OR LESS
THROUGH SUNSET...SO THE DEGREE OF ANY ORGANIZED CONVECTIVE
CLUSTERS WILL BE MAINLY DRIVEN BY MESOSCALE BOUNDARY COLLISIONS.
PLAN TO HIGHLIGHT A POTENTIAL FOR AT LEAST ISOLATED SEVERE TSTMS
IN THE HAZARDOUS WEATHER OUTLOOK.

IT WILL BE ANOTHER HOT AND HUMID DAY DESPITE THE UPPER RIDGE
RETROGRADING TO THE WEST. ATTM WE DO NOT BELIEVE CONDITIONS WILL
BE AS SULTRY AS SATURDAY...BUT HIGHS WILL MAKE A SOLID RUN FOR THE
MID-UPPER 90S AWAY FROM THE BEACHES. THE LOW-LEVEL FLOW HAS
ALREADY BACKED SOUTHERLY AT THE COAST AS WEAK LOW PRESSURE
MEANDERS NEAR ORANGEBURG AND COASTAL TEMPERATURES ARE ALREADY
RESPONDING BY RUNNING 1-3 DEGREES COOLER THAN 24 HOURS AGO. PLAN
TO NUDGE TEMPERATURES IN THE COASTAL CORRIDOR DOWN A FEW DEGREES
PER GOING TRENDS. DEWPOINTS ARE EXPECTED TO MIX OUT INTO THE UPPER
60-LOWER 70S INLAND THIS AFTERNOON WITH LOWER-MID 70S AT THE
COAST. THIS WILL STILL YIELD SEVERAL HOURS OF HEAT INDICES OF
105-108 DEGREES SO THE GOING HEAT ADVISORY LOOKS GOOD. WE WILL
LIKELY HAVE TO CANCEL PARTS OF THE ADVISORY LATER THIS AFTERNOON
AS TSTM COVERAGE INCREASES AND CONVECTIVE OUTFLOWS COOL THINGS
DOWN.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY/...
A WEAK SURFACE TROUGH WILL REMAIN IN PLACE ACROSS THE AREA TONIGHT.
UPPER LEVEL SUPPORT IN THE FORM OF PASSING SHORT WAVE DISTURBANCES...
COMBINED WITH ABUNDANT LOW LEVEL MOISTURE AND CONVERGENCE IN THE
VICINITY OF THE SURFACE TROUGH COULD SUPPORT CONVECTION ACROSS PART
OF THE AREA THROUGH MUCH OF THE NIGHT. AS A RESULT THE FORECAST
WILL SHOW A CHANCE OF SHOWERS AND THUNDERSTORMS THROUGH THE
EVENING WITH PROBABILITIES DIMINISHING A BIT OVERNIGHT...ESPECIALLY
ACROSS SOUTHEAST GEORGIA. TEMPERATURES WILL ONLY FALL TO LOWS IN
THE MID TO UPPER 70S AWAY FROM THE COAST.

UNSETTLED WEATHER ON TAP MONDAY AS DEEP MOISTURE COMBINES WITH A
TROUGH OF LOW PRESSURE INLAND TO YIELD A DECENT CHANCE OF SHOWERS
AND THUNDERSTORMS. THERE WILL BE A RISK OF HEAVY RAINFALL DUE TO
PWATS APPROACHING 2.5 INCHES AND SLOW STORM MOTIONS. COULD NOT
RULE OUT AN ISOLATED SEVERE STORM EITHER AS THE ENVIRONMENT COULD
BE FAVORABLE FOR DAMAGING WINDS FROM WET MICROBURSTS. TEMPERATURES
SHOULD BE HELD DOWN A BIT WITH THE INCREASED CLOUD COVER...
GENERALLY AROUND 90 DEGREES NORTH AND MID 90S ACROSS INTERIOR
SOUTHEAST GEORGIA.

SHOULD SEE IMPROVING CONDITIONS FOR TUESDAY AND WEDNESDAY AS THE
DEEPER MOISTURE SHIFTS OFFSHORE WITH THE UPPER HIGH PRESSURE TO THE
WEST NOSING EASTWARD. BEST RAIN CHANCES THESE DAYS WILL BE TUESDAY
FOR AREAS SOUTH OF INTERSTATE 16. MORE SUNSHINE WILL MEAN
TEMPERATURES REBOUNDING INTO THE MID TO UPPER 90S AWAY FROM THE
COAST WITH HEAT INDICES APPROACHING ADVISORY LEVELS TUESDAY AND
SURPASSING THEM WEDNESDAY.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/...
UPPER HIGH PRESSURE AND THE LACK OF DEEP MOISTURE SHOULD KEEP RAIN
CHANCES LOW THROUGH THURSDAY. BEYOND THAT THE FORECAST BECOMES A
BIT MORE UNCERTAIN AS MUCH DEPENDS ON THE EVENTUAL TRACK OF A LIKELY
TROPICAL CYCLONE WHICH THE GFS AND CANADIAN MODELS ARE SHOWING
MOVING NEAR OR JUST EAST OF THE BAHAMAS FRIDAY. FOR NOW HAVE
GENERALLY MAINTAINED A FORECAST PRETTY CLOSE TO CLIMATOLOGY FOR THIS
TIME OF YEAR WITH TEMPS IN THE 90S AND RAIN CHANCES NO HIGHER THAN
30 PERCENT.

&&

.AVIATION /14Z SUNDAY THROUGH THURSDAY/...
VFR CONDITIONS ARE GENERALLY EXPECTED TO PREVAIL AT KCHS AND KSAV
THROUGH 12Z MONDAY. SCATTERED SHOWERS AND THUNDERSTORMS ARE
EXPECTED TO DEVELOP THIS AFTERNOON IN THE VICINITY OF A WEAK SURFACE TROUGH
POSITIONED OVER THE AREA AND ALSO ALONG THE SEA BREEZE. ISOLATED
TO SCATTERED SHOWERS AND THUNDERSTORMS COULD THEN CONTINUE WELL INTO
TONIGHT...ESPECIALLY ACROSS SOUTHEAST SOUTH CAROLINA...DUE TO THE
LINGERING TROUGH AND PASSING UPPER LEVEL DISTURBANCES. THERE IS A
MENTION OF CB AT BOTH TERMINALS FROM 15Z-02Z...WITH VICINITY SHOWERS
IN THE 18-22Z TIME FRAME. HOWEVER AS MENTIONED...CONVECTION COULD
BE AN ISSUE LATER TONIGHT AS WELL BUT CONFIDENCE IS NOT HIGH
ENOUGH TO INDICATE THESE CONDITIONS IN THE FORECAST AT THIS TIME.
MVFR OR LOWER CONDITIONS WILL BE POSSIBLE WITHIN THUNDERSTORMS...ALONG
WITH THE POTENTIAL FOR GUSTY AND ERRATIC WINDS.

EXTENDED AVIATION OUTLOOK...HIGH CONFIDENCE FOR TSTMS WITH MVFR
OR LOWER CONDITIONS MONDAY.

&&

.MARINE...
A BROAD SOUTHERLY FLOW REGIME WILL DOMINATE THROUGH THE PERIOD
BETWEEN LOW PRESSURE INLAND AND HIGH PRESSURE OFFSHORE. CONDITIONS
ARE EXPECTED TO REMAIN BELOW ADVISORY LEVELS...ALTHOUGH SEAS COULD
BUILD LATE IN THE WEEK IF SWELLS FROM A POSSIBLE TROPICAL CYCLONE
NEAR THE BAHAMAS BEGIN TO IMPACT THE LOCAL WATERS.

&&

.CLIMATE...
RECORD HIGH TEMPERATURES FOR JULY 30

CHARLESTON INTERNATIONAL AIRPORT...100 SET IN 1999
DOWNTOWN CHARLESTON...98 SET IN 1942
SAVANNAH/HILTON HEAD INTERNATIONAL AIRPORT...101 SET IN 1896
