Severe Thunderstorm Warning 319, NWS Charleston, SC

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
314 PM EDT TUE SEP 16 2008

.SYNOPSIS...
A COLD FRONT WILL PUSH INTO THE COASTAL WATERS TONIGHT. THE FRONT
WILL STALL NEAR THE COAST WEDNESDAY THROUGH FRIDAY THEN LIFT BACK
NORTH OVER THE WEEKEND. SEVERAL WAVES OF LOW PRESSURE WILL DEVELOP
AND MOVE NORTHEAST ALONG THE FRONT THROUGH MONDAY.

&&

.NEAR TERM /THROUGH TONIGHT/...
16/19Z SURFACE ANALYSIS PLACED A PRONOUNCED FRONTAL WAVE BETWEEN
BEAUFORT AND ORANGEBURG WITH A STATIONARY FRONT EXTENDING SOUTH
FROM THE WAVE TOWARDS ALMA AND EAST THROUGH GEORGETOWN TO NEAR
BUOY 41013. PRESSURES CONTINUE TO SLOWLY RISE ACROSS THE MIDLANDS
AND THE NORTH CAROLINA PIEDMONT SO THE FRONT IS EXPECTED TO MAKE A
SLOW SOUTHWARD PROGRESS TONIGHT.

INSTABILITY CONTINUES TO POOL CROSS MUCH OF THE AREA THIS AFTERNOON
AND IS CHARACTERIZED BY MIXED LAYERED CAPE OF 1000-1500 J/KG AND
LIFTED INDICES OF -4 TO -7C. THE STRONGEST CONVERGENCE SO FAR HAS
BEEN MAINLY CONCENTRATED ALONG THE SOUTH SANTEE RIVER WHERE
SURFACE WINDS HAVE BACKED SLIGHTLY TO THE NORTHEAST OF THE FRONTAL
WAVE. VISIBLE SATELLITE TRENDS SUGGEST A LARGE CONVERGENCE ZONE IS
BEGINNING TO SETUP FROM WALTERBORO TO BEAUFORT EAST TO THE
CHARLESTON METRO AREA WHERE SOME TOWERING CUMULUS IS BEGINNING TO
FORM. EXPECT SCATTERED SHOWERS AND THUNDERSTORMS TO INITIATE IN
THIS AREA SOON...THEN GRADUALLY BECOME MORE CONCENTRATED THROUGH
THE LATE AFTERNOON AND INTO THIS EVENING AS A WELL DEFINED
VORTICITY MAX NEAR BRUNSWICK PROPAGATES UP ALONG THE SOUTH
CAROLINA/GEORGIA COAST. ANTICIPATE LESS CONVECTIVE COVERAGE ACROSS
SOUTHEAST GEORGIA WHERE WEAK NEGATIVE VORTICITY ADVECTION WILL
DEVELOP IN THE WAKE OF THE PASSING VORT CENTER OVER THE NEXT FEW
HOURS. WILL FORECAST 30-50 PERCENT POPS THROUGH THE EVENING
HOURS...KEEPING THE HIGHEST GRIDDED POPS FROM COLLETON AND
BEAUFORT COUNTIES EAST.

LATEST GUIDANCE SUGGESTS THE SURFACE FRONT WILL BE LOCATED
ALONG THE LOWER SOUTH CAROLINA COAST AND EXTENDING BACK TOWARDS
LUDOWICI BY SUNRISE WEDNESDAY. SLIGHTLY DRIER AIR OVER THE
MIDLANDS WILL MAKE A RUN FOR THE COAST LATE AS WINDS BACK MORE
NORTHERLY IN THE WAKE OF THE FRONT. LOWS WILL RANGE FROM THE MID
60S WELL INLAND TO THE LOWER 70S ALONG THE SOUTH CAROLINA COASTAL
ZONES AND THE LOWER TO MID 70S ALONG THE NORTH GEORGIA COAST.
PARTLY CLOUDY SKIES THIS EVENING WILL BECOME MOSTLY CLOUDY TONIGHT
AS ISENTROPIC LIFT INITIATES AND LOW-LEVEL MOISTURE POOLS BENEATH
THE POST FRONTAL INVERSION.

&&

.SHORT TERM /WEDNESDAY/...
VERY LOW CONFIDENCE ON EXACTLY HOW SENSIBLE WEATHER ELEMENTS WILL
PLAY OUT FOR WEDNESDAY. THE SURFACE COLD FRONT WILL MEANDER OFF THE
COAST WEDNESDAY MORNING WITH THE APPROACH OF THE UPPER TROUGH. THE
OPERATIONAL GFS REMAINS THE DRIEST OF THE VARIOUS MODELS WHILE THE
NAM...SHORT RANGE ENSEMBLE MEAN AND ECMWF OFFER SLIGHTLY WETTER
SOLUTIONS WITH VARIOUS INTENSITIES OF ISENTROPIC LIFT ACROSS THE
AREA. THE SREF HAS OFFERED GREAT CONTINUITY OVER THE PAST FEW DAYS
SO WILL GENERALLY FOLLOW ITS LEAD...KEEPING 40-50 PERCENT POPS IN
PLACE DURING THE MORNING HOURS THEN SHOWING A SLIGHT DECREASE IN
POPS THROUGH THE AFTERNOON AS THE CORE OF THE DRIER AIR FINALLY
BEGINS TO NUDGE IN FROM THE WEST. EXTENSIVE CLOUDINESS WILL RESULT
IN WELL BELOW NORMAL TEMPERATURES WITH HIGHS RANGING FROM AROUND
80 ACROSS THE SOUTH CAROLINA INTERIOR TO THE MID 80S ACROSS THE
SOUTHERN AREAS. ENOUGH INSTABILITY LOOKS TO REMAIN PLACE TO
CONTINUE A MENTION OF THUNDERSTORMS...ESPECIALLY ACROSS SOUTHEAST
GEORGIA AND THE COASTAL WATERS WERE INSTABILITY WILL BE THE
HIGHEST.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...
A WEAK UPPER LEVEL SHORTWAVE WILL PUSH OFFSHORE WED NIGHT WHILE THE
COLD FRONT SETTLES S OF THE AREA. A WEAK PRES PATTERN OFFSHORE
COMBINED WITH UPPER DIVERGENCE FROM THE SHORTWAVE WILL ALLOW FOR SCT
SHWRS OFFSHORE WED NIGHT INTO THU MORNING AS A WEAK AREA OF LOW PRES
DEVELOPS OVER THE WATERS. DURING THE DAY THU...DRIER AIR WILL MOVE
IN BEHIND THE CDFNT BUT NOT QUITE MAKE IT TO THE COAST AS THE LOW
PRES AREA ENHANCES OFF THE NC/SC COAST BEFORE IT MOVES OFF TO THE
NE...MAKING THE BEST CHCS FOR SHOWERS CLOSE TO THE COAST. EVEN
SO...POPS WILL BE CAPPED AT 30 AND ONLY CONFINED TO THE COASTAL
AREAS WHILE AREAS W OF ROUTE 17 WILL HAVE ONLY SLGT CHC POPS THU.

IN ADDITION TO DRIER AIR FOR WED NIGHT AND THU...COOLER AIR WILL
ALSO MOVE IN WHICH WILL MAKE FOR MIN TEMPS DROPPING TO THE LOW 60S
AWAY FROM THE COAST WED NIGHT AND MAX TEMPS IN THE LOW-MID 80S.

THE FRI-MON TIME FRAME BECOMES QUITE PROBLEMATIC DUE TO THE
AFOREMENTIONED CDFNT S OF THE AREA. AN UPPER LVL RIDGE WILL QUICKLY
MOVE W TO E ACRS THE AREA FRI AND FRI NIGHT...WHICH WILL HAVE ACTED
TO KEEP THE FNT TO THE S BUT THE FRONT NOW LOOKS TO DRIFT BACK TO
THE N STARTING LATE FRI AND WILL CONTINUE PUSHING N THROUGH THE
WEEKEND INTO EARLY NEXT WEEK. WITH BOTH THE GEM AND GFS SHOWING THIS
IDEA QUITE SIMILARLY...AM HAVING GROWING CONFIDENCE IN THIS SCHEME.
DEEPER MOISTURE PROFILES MOVE N IN CONJUNCTION WITH THE FNT WHILE
THE UPPER LEVEL PATTERN BECOMES PREDOMINANTLY ZONAL OVER THE AREA
ALTHOUGH SEVERAL MID-LVL SHORTWAVES LOOK TO MOVE THROUGH. IN
ADDITION...A FEW WAVES OF LOW PRES LOOK TO DEVELOP ALONG THE SFC
FRONT WHICH WOULD ENHANCE LLVL CONVERGENCE. THUS...HAVE INCRD POPS
INTO THE MID CHC RANGE WHICH IS STILL BELOW MOS GUIDANCE WHICH HAS
POPS IN THE 50-60 PERCENT RANGE. IN TURN...THIS MAY ALSO PREVENT
SOME AREAS FROM HAVING MAX TEMPS REACHING 80 DEGREES THROUGH THE
WEEKEND WHICH IS NOW REFLECTED IN THE EXTENDED RANGE.

FOR MON NIGHT INTO TUE...THE FRONT LOOKS TO GAIN IMPETUS FROM A
STRONG UPPER LEVEL RIDGE THAT WILL PUSH INTO THE AREA FROM THE W AND
MOVE INTO THE ATLC...DROPPING PRECIP CHCS INTO THE SLGT CHC RANGE
MAINLY DUE TO DIURNAL EFFECTS. TEMPS ALSO LOOK TO REBOUND CLOSER TO
NORMAL LEVELS FOR THE MIDDLE PORTION OF NEXT WEEK.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
VFR CONDITIONS ARE EXPECTED FOR BOTH KCHS AND KSAV THROUGH THE DAY
OUTSIDE ANY AFTERNOON CONVECTION. HAVE KEPT TEMPO GROUP FOR KCHS
WITH TSRA AND BRIEF PERIODS OF MVFR CEILINGS AS ISOLATED SHOWERS AND
THUNDERSTORMS HAVE BEGUN TO DEVELOP AROUND CHARLESTON COUNTY.
YET...EXPECT GUSTY WINDS AND REDUCE VISIBILITIES IN/NEAR ANY
THUNDERSTORMS. HAVE CB GROUPS MENTIONED FOR KSAV AS CONVECTION IS
POSSIBLE BUT EXPECTED TO REMAIN MAINLY NORTH OF THE TERMINAL. WITH
LIGHT WINDS...PLENTY OF LOW LEVEL MOISTURE ASSOCIATED WITH AFTERNOON
CONVECTION...AND CLOSE GUIDANCE AGREEMENT...HAVE KEPT MVFR FOG AND IFR
CEILINGS FOR BOTH TERMINALS OVERNIGHT. WILL CONTINUE TO MONITOR
LATEST GUIDANCE TRENDS FOR SOME INDICATE LOWER VISIBILITIES AND
CEILINGS...MAINLY FOR KSAV. INCLUDED CB GROUPS FOR WEDNESDAY
AFTERNOON AS SOME INSTABILITY LINGERS AROUND THE AREA. WILL REEVALUATE
TIMING AND COVERAGE OF CONVECTION FOR THE NEXT TAF PERIOD.

EXTENDED AVIATION OUTLOOK...A FRONTAL BOUNDARY WILL RESIDE SE OF
THE AREA WED THROUGH FRI. OCCASIONAL MVFR OR LOWER CONDITIONS
POSSIBLE THROUGH THE PERIOD. BEST CHANCES FOR LOWER CIGS WILL BE
DURING THE MORNINGS WITH OCNL CHANCES FOR SHOWERS AS WAVES OF LOW
PRES TRAVERSE THE FRONT OFF THE COAST.

&&

.MARINE...
SOUTHERLY WINDS WILL BECOME EAST TO NORTHEAST TONIGHT ACROSS THE
WATERS AS THE COLD FRONT WORKS SLOWLY IN FROM THE WEST. WINDS WILL
BECOME PREVAILING OUT OF THE NORTHEAST BY WEDNESDAY. SPEEDS 10 KT
OR LESS AND WITH SEAS 1-3 FT.

WEDNESDAY NIGHT THROUGH SUNDAY...BENIGN CONDS WILL PREVAIL WED
NIGHT THROUGH FRI WHILE A COLD FRONT REMAINS STALLED S OF THE
WATERS. THE FRONT WILL RETROGRADE BACK N STARTING LATE FRI AND
MAKE SLOW PROGRESS INTO THE WATERS THROUGH THE WEEKEND. AS IT
APPROACHES...THE PRES GRADIENT BETWEEN HIGH PRES OVER THE MID ATLC
STATES AND THE FRONT WILL ALLOW WIND SPEEDS TO INCRS OVER THE
WATERS AND MAY REACH SCA LEVELS OVER THE WEEKEND. CONFIDENCE IS
GROWING IN THIS IDEA THAT SCA HEADLINES MAY BE NEEDED OVER THE
WEEKEND...FOR AT LEAST THE OUTER GA WATERS...AS PERSISTENT NE
WINDS ARE EXPECTED FOR THE END OF THIS WEEK INTO EARLY NEXT WEEK.
DUE TO THIS PERSISTENT ONSHORE FLOW...WAVE HEIGHTS WILL GRADUALLY
INCREASE SUCH THAT WAVES MAY REACH UP TO 7 FT IN THE NEARSHORE
WATERS AND 9 FT IN THE OUTER GA WATERS OVER THE WEEKEND BEFORE
SUBSIDING EARLY NEXT WEEK WHEN THE FRONT DEPARTS.
