AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
735 AM EDT THU APR 3 2008

.SYNOPSIS...
A HIGH PRES SURFACE WEDGE OVER THE FORECAST AREA THIS MORNING
WILL WEAKEN TODAY AS A COASTAL WARM FRONT APPROACHES FROM THE S
AND SE. THE FRONT WILL LIFT N OF THE AREA BY LATE TONIGHT AS ATLC
HIGH PRES EXTENDS ACROSS FLORIDA AND SOUTHERN GEORGIA FRI. A COLD
FRONT WILL PUSH THROUGH THE REGION LATE SAT. HIGH PRES WILL RETURN
FOR EARLY NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
MID ATLC SFC HIGH PRES WAS NOSING THROUGH THE CAROLINAS INTO THE
SOUTHEAST GEORGIA THIS MORNING. AN ACTIVE RADAR CONTINUES PRIOR TO
DAWN ACROSS THE REGION AS SHOWERS AND TSTMS WERE TRAINING FROM
CANDLER COUNTY TO 10 MILES EITHER SIDE OF NEWINGTON GEORGIA. HEAVY
RAIN WAS OCNLY FALLING IN EXTREME SOUTHERN SOUTH CAROLINA...SOUTH
OF A LINE FROM ESTILL TO CHARLESTON. BOTH THE 06Z NAM AND GFS BOTH
PINPOINTING HIGHER QPF AMOUNTS ALONG AND TO THE N OF WHERE THE
CURRENT AXIS OF HEAVY CONVECTIVE RNFL EXISTS AT 11Z.

WE HAVE UPDATED GRIDDED/TEXT PRODUCTS TO RAISE POPS TO CATEGORICAL
TODAY IN THE AFOREMENTIONED REGION. WE ALSO ADDED RAIN HEAVY AT TIMES
TO SOME ZONES. THE KCLX WSR-88D HAS BEEN EXPERIENCING SOME RAIN
ATTENUATION...WHICH MAY BE CUTTING DOWN ON RADAR ESTIMATES A BIT.
STLT CLOUD TOPS HAD COOLED EARLIER TO -55C TO -65C WHICH SUGGESTED
SOME FLOOD POTENTIAL. THERE HAS BEEN A RECENT WARMING TREND BUT
NEW CELLS CONTINUE TO FIRE BETWEEN MACON AND VIDALIA.

PERSISTENCE USED ON MAX TEMPERATURES TODAY MID 70S FAR SRN ZONES
TO LOW/MID 60S IN ZONES BORDERING THE CENTRAL MIDLANDS. WE THINK
CLOUDS AND PCPN SHOULD HOLD TEMPERATURES IN CHECK TODAY WITH
WEAKENING WEDGE PATTERN.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/...
MODELS INDICATE THE COASTAL TROUGH ADVANCING N TONIGHT WITH THE
REGION LOSING THE SFC WEDGE OVERNIGHT. MODEL TRENDS LOOK PRETTY
GOOD...BUT MAY BE A BIT FAST ON SFC VEERING PATTERN. POPS WILL
BE ON THE WANE TONIGHT AS THE WARM SECTOR ADVANCES. TEMPERATURES
COULD RISE OVERNIGHT MANY AREAS AFTER MIDNIGHT. WE RAISED MIN
TEMPS MANY AREAS CLOSER TO THE COAST AND SRN ZONES IN GEORGIA.

FRI IS A DIFFERENT ANIMAL FROM TODAY...TIGHT LOW LEVEL PRES
GRADIENT WITH A SSW FLOW AND DEEPER MIXING. WE SHOULD BECOME
PARTLY CLOUDY MOST AREAS AND SUNSHINE WILL QUICKLY WARM TEMPS
INTO THE 80S ALONG WITH BREEZY TO WINDY CONDITIONS E OF I-95
IN SOUTH CAROLINA. MANY AREAS COULD REMAIN DRY FRI...BUT THERE
IS FORECAST TO BE A WEAK LEE-SIDE SFC TROF AND THE SEA BREEZE
MOVING INTO THIS FEATURE MAY SPARK A FEW TSTMS TO THE W OF
I-95 MID TO LATE AFTN. FORECAST CONVERGENCE AND INSTABILITY
PROGS SUGGEST ISOLATED STRONG TSTMS POSSIBLE OVER AREAS LIKE
FAR INLAND COLLETON...DORECHESTER...AND BERKELEY.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
A MILD SLY FLOW WILL BE IN PLACE FRI NIGHT AND A FEW SHOWERS ARE
POSSIBLE. RAIN CHANCES INCREASE SIGNIFICANTLY SAT...MAINLY FROM W
TO E...AS A COLD FRONT APPROACHES FROM THE W AND THE AREA GETS
INTO THE RIGHT REAR QUADRANT OF A 130+ KT H25 JET. WITH THE FRONT
EXPECTED TO BE A BIT SLOWER THAN PREVIOUSLY THOUGHT...ALLOWING FOR
A BIT MORE INSTABILITY...WILL HAVE TO KEEP AN EYE OUT FOR THE
POTENTIAL FOR A FEW STRONG TO POSSIBLY SEVERE STORMS SAT AFTN/EVE.
SLOW CLEARING EXPECTED SAT NIGHT AS HIGH PRES TRIES TO BUILD IN N
OF THE AREA. HOWEVER... NUMERICAL GUIDANCE IS SUGGESTING AT LEAST
ONE AREA OF LOW WILL DEVELOP ON THE FRONT S OF THE AREA THROUGH
MID WEEK...POSSIBLY TRACKING CLOSE ENOUGH TO KEEP RAIN AT LEAST
ALONG THE COAST.

TEMPS WILL START THE PERIOD ABOVE NORMAL AHEAD OF THE FRONT...THEN
RETURN TO MORE NORMAL LEVELS THROUGH THE REMAINDER OF THE PERIOD.

&&

.AVIATION /11Z THURSDAY THROUGH MONDAY/...
BAND OF RAIN WITH EMBEDDED CONVECTION ACROSS THE REGION EARLY
THIS MORNING BETWEEN THE KSAV AND KCHS AIRPORTS FOR THE MOST
PART. MODEL OUTPUT INDICATES RAIN WILL BE MORE WDSPRD AND HEAVIER
AT KCHS LATER TODAY WHICH IS REASONABLE LOOKING AT RECENT RADAR
TRENDS. ISOLD TSTMS ARE POSSIBLE TODAY AROUND CHARLESTON. STORMS
FROM STATESBORO TO NORTHERN JASPER COUNTY WILL LIKELY REMAIN N OF
KSAV THROUGH MID MORNING.

IFR CIGS FINALLY DEVELOPED AT KSAV THIS MORNING...SHOULD LIFT TO
MVFR THIS AFTERNOON. CIGS AT KCHS HAVE BEEN STUBBORN TO LOWER
BELOW 1500 FT OVERNIGHT...FINALLY AFTER 11Z...CIGS HAVE FALLEN
TO IFR. WDSPRD RNFL SUGGEST CIGS WILL BE VERY SLOW TO LIFT FROM
CURRENT VALUES THIS MORNING.

REMAINDER OF TAF CYCLE CONTINUES PERSISTENCE OVERALL. WILL NEED
TO WATCH FOR FOG AND STRATUS CONCERNS TONIGHT.

EXTENDED AVIATION OUTLOOK...MVFR OR LOWER CIGS/FOG POSSIBLE EARLY
FRI...THEN VFR CONDITIONS DEVELOPING FRI. MVFR OR LOWER CONDITIONS
POSSIBLE AGAIN SAT AND SAT NIGHT. VFR DEVELOPING SUN AND
CONTINUING MON.
