AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
234 PM EDT THU MAY 31 2012

.SYNOPSIS...
WEAK ATLANTIC HIGH PRESSURE WILL GIVE WAY TO A COLD FRONT MOVING
THROUGH THE AREA FRIDAY NIGHT...FOLLOWED BY HIGH PRESSURE THROUGH
THE WEEKEND. ANOTHER COLD FRONT WILL GRADUALLY ADVANCE INTO THE
SOUTHEAST THROUGH THE FIRST HALF OF NEXT WEEK...AND HIGH PRESSURE
COULD BUILD INTO THE REGION AGAIN AROUND MIDWEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
EARLY THIS AFTERNOON...CONVECTION HAS INITIATED OVER SE GA WHERE
DEWPOINTS REMAINED IN THE LOW 70S THIS AFTERNOON. WITH TEMPS
APPROACHING 90 IN THE MOIST LOW LEVEL AIRMASS...CAPE VALUES HAVE
INCREASED INTO THE 2500-3000 J/KG RANGE. THE CONSIDERABLE SURFACE
BASED INSTABILITY...COMBINED WITH DCAPE VALUES IN EXCESS OF 1000
J/KG WILL RESULT IN SEVERAL STRONG TO SEVERE STORMS IN THIS AREA
CAPABLE OF PRODUCING LARGE HAIL AND STRONG DOWNBURST WINDS. WILL
ADD A MENTION TO THE HWO FOR THE REMAINDER OF THE AFTERNOON. ON
THE FLIP SIDE...DEWPOINTS HAVE MIXED OUT ACROSS SOUTHERN SC INTO
THE MID 50S IN SOME AREAS AND LITTLE TO NO CONVECTION IS EXPECTED
THERE.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY/...
TONIGHT...ANY ISOLATED EVENING CONVECTION IN THE SOUTHWEST ZONES
WILL LIKELY DISSIPATE AS DIURNAL HEATING/INSTABILITY WANES AFTER
SUNSET. A PROMINENT SHORTWAVE TROUGH AND ASSOCIATED SURFACE COLD
FRONT WILL BE STEADILY APPROACHING FROM THE WEST THROUGH EARLY
FRIDAY MORNING...HOWEVER BEST FORCING AND DEEP MOISTURE WILL STILL
BE WELL OUTSIDE OF THE FORECAST AREA BY DAYBREAK FRIDAY. FORECAST
MODEL SOUNDINGS INDICATE LOW LEVEL MOISTURE BECOMING TRAPPED
BENEATH THE INVERSION LATE TONIGHT...POSSIBLY SUPPORTING STRATUS
AND LIGHT FOG DEVELOPMENT. LOW TEMPERATURES WILL AGAIN BE QUITE
MILD...ONLY FALLING INTO THE UPPER 60S AND LOWER 70S.

FRIDAY INTO FRIDAY NIGHT...AN APPROACHING UPPER TROUGH AND
ASSOCIATED SURFACE COLD FRONT WILL SUPPORT SCATTERED TO BROKEN
CONVECTION ESPECIALLY DURING THE AFTERNOON/EVENING. THERMODYNAMIC/
KINEMATIC PARAMETERS SUPPORT MULTICELL THUNDERSTORMS CAPABLE OF
PRODUCING EPISODES OF DAMAGING WIND GUSTS AND LARGE HAIL.
ACCORDINGLY...AREAS ALONG AND NORTH OF INTERSTATE 16 REMAIN IN A
SLIGHT RISK FOR SEVERE THUNDERSTORMS...AND WE WILL CONTINUE TO
ADDRESS THIS THREAT WITHIN THE HAZARDOUS WEATHER OUTLOOK.

POPS REMAIN UNCERTAIN. WHILE THUNDERSTORMS COULD BECOME
NUMEROUS...JUSTIFYING LIKELY OR HIGHER POPS...GUIDANCE HAS TRENDED
TOWARD LOWER POPS...SUGGESTING THAT BEST COVERAGE OF THUNDERSTORMS
WILL REMAIN NORTH OF THE REGION. FOR NOW...CAPPED HIGHEST POPS IN
THE 40-50 PERCENT RANGE FRIDAY AFTERNOON INTO FRIDAY EVENING.

SATURDAY...IN THE WAKE OF COLD FROPA A DRIER AIR MASS FEATURING
DEWPOINTS IN THE MID 50S TO LOWER 60S WILL OVERSPREAD THE REGION.
SOME GUIDANCE SUGGESTS THAT SUFFICIENT MOISTURE WILL PERSIST TO
SUPPORT ISOLATED SHOWERS/THUNDERSTORMS ESPECIALLY WHERE SEA BREEZE
CONVERGENCE DEVELOPS NEAR THE COAST. THIS SCENARIO JUSTIFIES
NON-ZERO POPS...BUT GIVEN THE INCREASINGLY DRY/CAPPED ENVIRONMENT
HELD POPS BELOW 15 PERCENT WITH NO EXPLICIT MENTION OF
PRECIPITATION. TEMPERATURES SHOULD TOP OUT IN THE MID TO UPPER 80S.
SATURDAY NIGHT SHOULD FEATURE BELOW NORMAL TEMPERATURES IN THE LOWER
TO MID 60S.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
THE UNSEASONABLY DRY AIR MASS WILL REMAIN IN PLACE SUNDAY.
TEMPERATURES WILL RECOVER INTO THE UPPER 80S TO LOWER 90S... BUT
DEWPOINTS WILL REMAIN IN THE UPPER 50S/LOWER 60S. POPS ARE
ESSENTIALLY ZERO SUNDAY.

NEXT WEEK...A BLOCKING PATTERN WILL DEVELOP...ALLOWING A LONGWAVE
UPPER TROUGH TO AMPLIFY OVER THE EAST. THIS TROUGH WILL GRADUALLY
PUSH A SLOW-MOVING SURFACE COLD FRONT INTO THE SOUTHEAST DURING THE
FIRST HALF OF THE WEEK. THUS...INTRODUCED SLIGHT CHANCE POPS DURING
THE MONDAY AND TUESDAY TIME FRAME...AND HIGHER POPS COULD EVENTUALLY
BE REQUIRED FOR A PORTION OF THAT TIME PERIOD. EVEN AS HIGH PRESSURE
EXPANDS FROM THE NORTH AROUND MIDWEEK...STRONG DRYING IS NOT
INDICATED...AND LOW CHANCE POPS ARE JUSTIFIED. OVERALL...THIS
PATTERN WILL NOT FAVOR ANY HOT/HUMID WEATHER...AND TEMPERATURES
SHOULD REMAIN CLOSE TO OR EVEN SLIGHTLY BELOW NORMAL NEXT WEEK.

&&

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
AT KSAV...A STRONG TO SEVERE THUNDERSTORM PRODUCING HAIL AND WIND
GUSTS TO AROUND 45 KTS QUICKLY DEVELOPED RIGHT ON TOP OF THE
AIRFIELD RECENTLY. THIS CLUSTER OF STORMS WILL REMAIN IN THE AREA FOR THE
NEXT HOUR OR SO AND SHOULD BEGIN TO DIMINISH AND MOVE AWAY AFTER
THAT. WILL CONTINUE VCTS AND CB MENTION THERE FOR THE AFTERNOON.

AT KCHS...CONVECTION WILL BE TOUGH TO COME BY WITH DEWPOINTS
MIXING OUT INTO THE MID 50S THIS AFTERNOON. LATER TONIGHT A FEW
SHOWERS/STORMS COULD BE IN THE GENERAL AREA AS A WEAK WARM FRONT
LIFTS NORTHWARD ACROSS THE AREA. I THINK THE COVERAGE WILL BE LOW
ENOUGH TO NOT MENTION IN THE FORECAST FOR NOW...BUT AMENDMENTS MAY
BE NEEDED DEPENDING ON HOW THINGS EVOLVE AND OUTFLOW BOUNDARIES
INTERACT FROM SE GA.

OVERNIGHT...THE FOCUS TURNS TO THE POTENTIAL FOR FOG AND/OR
STRATUS. AS THE WARM FRONT LIFTS NORTHWARD...A 20-25 KT LOW LEVEL
JET WILL PUSH ACROSS THE AREA. THIS PERSISTENT FLOW IN THE LOWEST
FEW THOUSAND FEET OF THE ATMOSPHERE SHOULD BE ENOUGH TO PREVENT
FOG FORMATION. MODEL SOUNDINGS AND TIME HEIGHTS DEPICT SOME DECENT
LOW LEVEL MOISTURE...AND THIS SHOULD ALLOW FOR THE DEVELOPMENT OF
SOME STRATUS. STILL...THE MODEL GUIDANCE SUITE IS A BIT MIXED AND
CONFIDENCE ISN/T HIGH ENOUGH TO BRING ANY CEILING RESTRICTIONS
INTO THE FORECAST. WILL CONTINUE TO HINT AT THE PRESENCE OF
STRATUS WITH SCT MVFR TO IFR CLOUDS. PROBABILITY IS LIKELY HIGHER
AT KSAV COMPARED TO KCHS.

EXTENDED AVIATION OUTLOOK...A COLD FRONT WILL CROSS THE REGION LATE
FRIDAY AND FRIDAY NIGHT...LIKELY RESULTING IN BRIEF SUB-VFR FLIGHT
CONDITIONS IN SHRA/TSRA. OTHERWISE...VFR.

&&

.MARINE...
TODAY...THE PRESSURE GRADIENT WILL BE RELATIVELY WEAK FOR THE
START OF THE DAY...ALLOWING WIND FIELDS TO BE MOSTLY DRIVEN BY
SEABREEZE DEVELOPMENT THIS AFTERNOON. TONIGHT...AS A STRONG COLD
FRONT STEADILY PROGRESSES FROM THE WEST...SOUTH/SOUTHWEST FLOW
WILL INCREASE ACROSS THE MARINE ZONES. DESPITE ANY WEAK SURGING
AHEAD OF THE APPROACHING SYSTEM OVERNIGHT...WIND SPEEDS ARE STILL
EXPECTED TO REMAIN 15 KT OR LESS...WITH SEAS NO MORE THAN 2 OR 3
FT.

FRIDAY AND FRIDAY EVENING...A TIGHT SURFACE PRESSURE GRADIENT
BETWEEN ATLANTIC HIGH PRESSURE AND AN APPROACHING COLD FRONT FROM
THE WEST AND NW WITH SUPPORT S/SW WINDS IN THE 15-20 KT
RANGE...CAUSING SEAS TO BUILD TO 3-5 FT. MARGINAL SMALL CRAFT
ADVISORY WINDS COULD DEVELOP FRIDAY AFTERNOON INTO FRIDAY
EVENING...BUT THE PROBABILITY REMAINS INSUFFICIENT TO JUSTIFY A
SMALL CRAFT ADVISORY WITHIN THE EARLY THURSDAY MORNING FORECAST
PACKAGE.

MARINERS SHOULD REMAIN ALERT FOR THE POSSIBILITY OF STRONG TO SEVERE
T-STORMS IN ADVANCE OF THE COLD FRONT...ESPECIALLY LATE FRIDAY INTO
FRIDAY NIGHT.

SATURDAY AND SUNDAY...WEAK HIGH PRESSURE WILL BUILD FROM THE WEST AS
THE COLD FRONT PULLS FAR AWAY TO THE EAST AND SE. A LIGHT OFFSHORE
WIND REGIME WILL PREVAIL...WITH NO MORE THAN WEAK SEA BREEZE
CIRCULATION DEVELOPING EACH AFTERNOON.

MONDAY AND TUESDAY...A SLOW-MOVING COLD FRONT WILL APPROACH FROM THE
NORTH. SOUTH TO SOUTHWEST WINDS WILL PREVAIL. MONDAY...WINDS MAINLY
10 KT OR LESS WILL BE ACCOMPANIED BY 1-2 FT SEAS. TUESDAY...WINDS
SHOULD INCREASE AND SEAS WILL BUILD...INTRODUCING A LOW PROBABILITY
FOR SMALL CRAFT ADVISORY CONDITIONS.
