Special Weather Statement, NWS Charleston, SC

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
129 PM EDT SAT AUG 13 2011

.SYNOPSIS...
AN ILL DEFINED STATIONARY FRONT OVER SOUTH CAROLINA WILL DRIFT
NORTH THROUGH TONIGHT. A COLD FRONT WILL APPROACH THE REGION FROM
THE WEST LATE SUNDAY...AND MOVE OFFSHORE AND INTO THE ATLANTIC
SUNDAY NIGHT. HIGH PRESSURE WILL THEN REBUILD OVER THE AREA
THROUGH MUCH OF NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
AN AREA OF MOISTURE CONVERGENCE THAT SPURRED A FEW SHOWERS AND
THUNDERSTORMS ACROSS FAR NORTHEASTERN ZONES EARLY THIS MORNING
CONTINUES TO SHIFT NORTHEAST AWAY FROM THE FORECAST AREA. HOWEVER
A DIFFUSE SURFACE TROUGH APPEARS TO STILL BE DRAPED ACROSS THE
CHARLESTON TRI-COUNTY AREA PER DEWPOINTS POOLED IN THE MID TO
UPPER 70S. TEMPERATURES ARE WARMING NICELY IN MOST AREAS UNDER
SUNNY TO MOSTLY SUNNY SKIES. WE EXPECT TEMPERATURES TO TOP OUT IN
THE LOWER 90S IN EASTERN AREAS AND MIDDLE 90S INTERIOR SC/GA.

ANALYSIS OF OUR 12Z RAOB SHOWS A JUICY AIRMASS WITH QUITE A BIT OF
CONVECTIVE POTENTIAL SHOULD ENOUGH FORCING INITIATE ACTIVITY. THE
POTENTIAL CAVEAT IS SOME MID-LEVEL WARMING THROUGH THE DAY AROUND
500 MB. THIS WOULD TEND TO LIMIT THE VERTICAL ACCELERATION OF
UPDRAFTS. HOWEVER MOST OTHER INDICES FAVOR SOME STRONG TO POSSIBLY
SEVERE THUNDERSTORMS...ESPECIALLY LATER THIS AFTERNOON ONCE THE
SEABREEZE AND CONVECTIVE OUTFLOW BOUNDARIES ALL BEGIN COLLIDING.
THE FIRST SHOWERS/STORMS EXPECTED TO DEVELOP ON THE SEABREEZE
EARLY THIS AFTERNOON. AFTER THAT...IT IS TOUGH TO PIN DOWN
CONVECTIVE COVERAGE AS IT IS HIGHLY DEPENDENT ON THE RANDOM
INTERACTIONS OF CONVECTIVE BOUNDARIES. WE DID NOT MAKE ANY CHANGES
TO TODAY/S POPS...WHICH MOVE THE BEST COVERAGE INLAND LATE IN THE
DAY.

SIMILAR TO FRIDAY...ALL CONVECTION WILL PRODUCE TORRENTIAL
DOWNPOURS AND FREQUENT LIGHTNING. ISOLATED WET MICROBURSTS WOULD
BE THE PRIMARY SEVERE THREAT SINCE THE ATMOSPHERE IS QUITE WARM
AND WOULD TAKE A LOT TO PRODUCE SEVERE HAIL.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH TUESDAY/...
EVENING CONVECTION...MAINLY OVER INLAND AREAS WILL WANE GRADUALLY
AFTER SUNSET. LATER TONIGHT...VEERING LOW LEVEL SYNOPTIC FLOW AND
THE LAND BREEZE WILL PROBABLY IGNITE ISOLATED TO LOCALLY SCATTERED
SHOWERS AND TSTMS TO THE E OF I-95 IN SOUTH CAROLINA AND ESPECIALLY
CLOSER TO THE BEACHES. WE SHOW A SLIGHT UPTICK IN NOCTURNAL POPS
IN THESE AREAS...STILL MAINLY BELOW 30 PERCENT.

SUNDAY AND SUNDAY NIGHT...MODEL GUIDANCE IS IN GOOD AGREEMENT
SHOWING A COLD FRONT APPROACHING FROM THE WEST THROUGH THE
DAY...THEN MOVING OFFSHORE AND INTO THE ATLANTIC OVERNIGHT. THE
COLD FRONT IN COMBINATION WITH GOOD DYNAMIC SUPPORT FOR ASCENT
PROVIDED BY A DEEP UPPER LEVEL TROUGH AND ENTRANCE REGION FORCING
FROM A 70+ KNOT H25 JET...ALONG WITH THE INLAND SEA BREEZE
PUSH...SHOULD BE ENOUGH FAIRLY WIDESPREAD SHOWER/THUNDERSTORM
COVERAGE ACROSS THE FORECAST AREA. HAVE THEREFORE INCREASED POPS
INTO THE LIKELY RANGE ACROSS THE VAST MAJORITY OF THE FORECAST
AREA...FOR PRIMARILY AFTERNOON/EVENING CONVECTION.

CONVECTIVE EVOLUTION WILL BE A BIT MORE DIFFICULT TO PIN DOWN AT
THIS TIME...WITH MODEL SOLUTIONS SUGGESTING A VARIETY OF POSSIBLE
SCENARIOS. WITH THE GLOBAL MODELS IN FAIRLY GOOD AGREEMENT WITH THE
POSITIONING/PROGRESSION OF THE LARGE SCALE SYNOPTIC FEATURES
HOWEVER...FEEL THAT THE INCREASING DEEP LAYER SOUTHWESTERLY FLOW
WILL HAVE SHIFTED ANY ONGOING CONVECTION OFFSHORE PRIOR TO DAYBREAK
SUNDAY. AS A RESULT...WOULD EXPECT THAT THE NAM AND TO A LESSER
EXTENT THE GFS SOLUTIONS ARE A BIT OVERDONE WITH CONVECTION AND
ASSOCIATED DEBRIS CLOUDINESS SUNDAY MORNING. WOULD EXPECT AT LEAST
SOME DECENT SURFACE HEATING THROUGH THE MORNING HOURS ACTING TO
DESTABILIZE THE ATMOSPHERE PRIOR TO CONVECTIVE DEVELOPMENT. THE GEM
REGIONAL SEEMS TO FOLLOW THIS LINE OF THINKING AND WILL LEAN THE
FORECAST HEAVILY IN IT/S DIRECTION.

ASSUMING DECENT MORNING DESTABILIZATION...ADJUSTING MODEL SOUNDINGS
FOR FORECAST AFTERNOON TEMPERATURES/DEWPOINTS YIELDS CAPE VALUES OF
2500-3000 J/KG AND LI/S OF -7 TO -8...MORE THAN ENOUGH INSTABILITY
FOR ORGANIZED MULTI-CELLULAR THUNDERSTORM DEVELOPMENT GIVEN THE
DYNAMIC FORCING FOR ASCENT THAT WILL BE PRESENT. AS A
RESULT...SEVERE THUNDERSTORMS CONTINUE TO LOOK LIKE A DECENT
POSSIBILITY ACROSS THE REGION...AND WILL CONTINUE TO HIGHLIGHT THIS
IN THE HAZARDOUS WEATHER OUTLOOK. THE MAIN HAZARDS FROM THE
STRONGEST STORMS THAT DEVELOP CONTINUE TO LOOK LIKE DAMAGING
STRAIGHT LINE WINDS AND MARGINALLY SEVERE HAIL.

CONVECTION SHOULD WIND DOWN RATHER QUICKLY SUNDAY EVENING...WITH NO
HIGHER THAN SLIGHT CHANCE POPS WARRANTED AFTER MIDNIGHT. AFTER
MIDNIGHT...DEEP MOISTURE AND A SYNOPTIC SHIFT TO SW FLOW WILL LIKELY
KICK OFF SCATTERED CONVECTION ALONG AND NEAR THE SOUTH CAROLINA
COAST WITH ASSISTANCE FROM A LAND BREEZE COMPONENT.

MONDAY THROUGH TUESDAY...GLOBAL MODEL SOLUTIONS ARE IN GOOD
AGREEMENT SHOWING THAT THE DEEPEST MOISTURE AND BEST FORCING FOR
ASCENT OFFSHORE PRIOR TO DAYBREAK MONDAY. AS A RESULT...EXPECT
THAT HIGH PRESSURE AND A DRIER AIRMASS BOTH AT THE SURFACE AND
ALOFT WILL BUILD BACK INTO THE REGION THROUGH THE EARLY WEEK
PERIOD. WILL KEEP THE FORECAST FREE FROM RAIN...WITH HIGHS
EXPECTED TO TOP OUT IN THE LOW TO MID 90S AWAY FROM THE COAST EACH
DAY. LOWS MONDAY NIGHT WILL RANGE FROM THE UPPER 60S WELL INLAND
TO THE LOWER/MIDDLE 70S ALONG THE COAST.

&&

.LONG TERM /TUESDAY NIGHT THROUGH FRIDAY/...
MODEL SOLUTIONS ARE IN FAIRLY DECENT AGREEMENT THROUGH THE LONG TERM
PERIODS...SHOWING HIGH PRESSURE HOLDING IN PLACE OVER THE REGION
THROUGH WEDNESDAY NIGHT. SURFACE TROUGHING IS THEN EXPECTED TO
DEVELOP IN THE LEE OF THE APPALACHIANS FOR THE END OF THE WEEK AND
INTO THE UPCOMING WEEKEND...ALONG WITH LOWERING UPPER LEVEL HEIGHTS.
AS A RESULT...WILL KEEP THE FORECAST RAIN FREE TUESDAY NIGHT THROUGH
WEDNESDAY NIGHT. WILL THEN NEED SLIGHT CHANCE/LOW CHANCE POPS IN THE
FORECAST THURSDAY THROUGH SATURDAY. TEMPERATURES ARE EXPECTED TO RUN
NEAR TO SLIGHTLY ABOVE CLIMATOLOGY THROUGH THE PERIOD.

&&

.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
HAVE MAINTAINED VFR CONDITIONS THROUGH THE 18Z TAF PERIOD FOR BOTH KCHS
AND KSAV...HOWEVER AS CONVECTION DEVELOPS ALONG THE SEA BREEZE AND
OTHER BOUNDARIES THIS AFTERNOON...EXPECT AMENDMENTS WILL BE NEEDED.
CONVECTION WILL INITIATE ACROSS THE CHARLESTON AREA THEN TRANSITION
SOUTHWARD. CONVECTION WILL LIKELY LINGER A COUPLE HOURS AFTER SUNSET
AT KSAV WITH DEBRIS CLOUDS PERSISTING OVERNIGHT AT BOTH SITES. SOME
MODEL SOUNDINGS SUGGEST SOME MVFR CEILINGS COULD AFFECT THE
TERMINALS EARLY SUNDAY MORNING AS POSSIBLE SHOWERS DEVELOP IN
ASSOCIATION WITH THE LAND BREEZE. A COLD FRONT WILL APPROACH SUNDAY
BRINGING POTENTIAL FOR ADDITIONAL THUNDERSTORMS.

EXTENDED AVIATION OUTLOOK...SCATTERED SHOWERS AND THUNDERSTORMS MAY
BRIEFLY REDUCE VSBYS AND/OR CIGS SUNDAY...PRIMARILY DURING THE
AFTERNOON AND EVENING HOURS. OTHERWISE VFR CONDITIONS SHOULD
PREVAIL.

&&

.MARINE...
LIGHT WINDS SHOULD BECOME SE THIS AFTERNOON WITH SPEEDS MAINLY
BELOW 15 KT AND SEAS 1-3 FT. THE FLOW WILL CONTINUE TO SLOWLY VEER
TO S AND SW TONIGHT A SYNOPTIC SCALE UPPER SYSTEM APPROACHES FROM
THE WNW AND HIGH PRES OFF THE MID ATLC COAST ERODES. A MODERATE 15
KT SURGE IS POSSIBLE TONIGHT AS NOCTURNAL JETTING BECOMES MORE
FAVORABLE. SEAS REMAIN MOSTLY AT OR BELOW 3 FT TONIGHT.

SUNDAY THROUGH THURSDAY...A COLD FRONT WILL APPROACH FROM THE
WEST ON SUNDAY...THEN MOVE THE WATERS SUNDAY NIGHT. HIGH PRESSURE
WILL THEN BUILD OVER THE AREA THROUGH MUCH OF THE UPCOMING WEEK.
COULD SEE A BIT OF A SURGE IN THE WINDS PRIOR TO THE COLD FRONT
PASSAGE SUNDAY NIGHT...BUT WINDS AND SEAS ARE EXPECTED TO FALL
SHORT OF SMALL CRAFT THRESHOLDS. OTHERWISE...NO SIGNIFICANT MARINE
ISSUES ARE EXPECTED THROUGH THE PERIOD.

&&

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