AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
359 PM EDT THU APR 2 2009

.SYNOPSIS...
A WARM FRONT WILL LIFT N THROUGH THE AREA THIS EVENING...WHILE
WAVES OF LOW PRESSURE MOVE INTO THE SOUTHEAST STATES FROM THE GULF
OF MEXICO. A COLD FRONT WILL THEN PUSH THROUGH THE AREA BY LATE
FRIDAY MORNING. HIGH PRESSURE WILL BUILD OVER THE REGION FRIDAY
THROUGH SATURDAY NIGHT. LOW PRESSURE WILL BEGIN TO IMPACT THE
REGION SUNDAY AND WILL PULL A COLD FRONT THROUGH THE AREA BY
MONDAY...THEN ANOTHER COLD FRONT WILL CROSS THE REGION TUESDAY.
HIGH PRESSURE WILL THEN BUILD INTO THE REGION THROUGH MIDWEEK.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
SFC ANALYSIS PUTS THE WAVERING STNRY FRONT STILL OVER SRN GA WITH
A COLD FRONT MOVING THROUGH THE LOWER MISS RIVER VALLEY. OBS
WITHIN THE CHS CWFA HAVE SHOWN TEMPS IN THE 60S AND PRIMARILY E TO
N WINDS. S OF THE ALTAMAHA RIVER...TEMPS ARE IN THE MID-UPR 70S
WITH MORE SLY WINDS AND DEWPOINTS WELL INTO THE 60S. WIDESPREAD
RAIN WITH EMBEDDED TSTMS EARLIER HAVE SLACKENED OFF SOME...ESP IN
NRN PORTIONS OF THE AREA THAT ARE FURTHER FROM THE FRONT.
MEANWHILE...SRN PORTIONS CONTINUE TO SEE MOD/HVY RAIN AND SEVERAL
REPORTS OF FLOODING HAVE BEEN RECEIVED FROM SE GA.

WILL LOOK FOR THE FRONT TO REMAIN S OF THE AREA THROUGH
SUNSET...THEN GRADUALLY LIFT N THROUGH THE ENTIRE CWFA THIS
EVENING INTO THE EARLY MORNING HOURS. THIS WILL PUT THE ENTIRE
CWFA SQUARELY WITHIN THE WARM SECTOR OF THIS SYSTEM. HOWEVER...
THE HEAVY RAIN SHOULD CEASE BY MID-TO-LATE EVENING AS MODELS SHOW
SOME DRY SLOTTING AHEAD OF THE COLD FRONT. THIS MATCHES FAIRLY
WELL THE WV IMAGERY DEPICTION OF DRY AIR PUNCHING INTO LA/MS AHEAD
OF THE COLD FRONT. THOUGH THIS MAY END THE HEAVY RAIN THREAT BY
MID-LATE EVENING...ATTENTION THEN TRANSITIONS TO POSSIBLE SEVERE
WX.

THE RISING DEWPOINTS WILL HELP TO AID GROWING INSTABILITY...
PUTTING CAPE IN THE 500-1000 J/KG RANGE WITH THE HIGHEST OF THAT
RANGE NEAR SRN PORTIONS OF THE CHS CWFA. MEANWHILE...STRONG PRE-
FRONTAL WIND FIELDS...INCLUDING 40-50 KT AT 925MB AND 50-60 KT AT
850MB AND STRONG UPPER LEVEL DIVERGENCE...WILL HELP AID THE
DEVELOPMENT OF A FEW EMBEDDED SUPERCELLS CAPABLE OF PRODUCING
DAMAGING WINDS AND/OR ISOLD TORNADOES. SPC KEEPS THE MOD RISK OF
SEVERE JUST S OF THE CHS CWFA BECAUSE OF UNCERTAINTY IN THE DEGREE
OF INSTABILITY...BUT SOLID SLGT RISK IS VALID.

ORGANIZED/WIDESPREAD PRECIP WITH TSTMS SHOULD EVENTUALLY COME TO
AN END IN THE 06Z- 09Z TIMEFRAME ACROSS THE AREA ALTHOUGH THERE
MAY BE SOME STRAGGLERS IN THE PRE-DAWN HOURS. HAVE HIGHLIGHTED
CATEGORICAL POPS IN THE EVENING TO EARLY OVERNIGHT HOURS...THEN
DROPPING BACK DOWN TO CHC POPS LATE OVERNIGHT.

AS FOR TEMPS...MOST OF THE AREA WAS HELD IN THE 60S. CONSIDERING
THE WARM FRONT WILL LIFT N THROUGH THE AREA OVERNIGHT...TEMPS WILL
GENERALLY REMAIN FAIRLY STEADY IN THE LOW-MID 60S OUTSIDE OF
LOCALIZED TEMP DROPS DUE TO RAINFALL.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH 6 PM FRIDAY/...
PRECIP SHOULD BE OFFSHORE BY DAYBREAK FRI MORNING WHILE THE COLD
FRONT IS STILL WELL INLAND OF THE AREA. THE FRONT LOOKS TO PUSH
THROUGH LATE MORNING...ALLOWING FOR A STEADY CLEARING OF SKIES
ALONG WITH A WIND SHIFT TO W-NW. IN ADDITION...STRONG SUBSIDENCE
WILL ALLOW FOR DEEP MIXING OF THE STRONG LLVL WINDS TWD THE SFC
CREATING BREEZY CONDITIONS OVER THE AREA. TEMPS WILL BE RATHER
MILD...RISING TO THE MID-UPR 70S AS THERE IS NOT MUCH OF A PUNCH
OF COLD AIR ADVECTION BEHIND THIS FRONT. SKIES SHOULD BE MOSTLY
CLEAR IF NOT COMPLETELY CLEAR BY LATE IN THE DAY.

LAKE WINDS...STRONG MIXING WITHIN THE LOWEST LEVELS DUE TO THE
COLD FRONT WILL INCREASE WIND SPEEDS SIGNIFICANTLY OVER LAKE
MOULTRIE. THEREFORE...HAVE OPTED TO RAISE A LAKE WIND ADVY FOR
FRI...MAINLY CONCENTRATING ON MID-MORNING TO EARLY EVENING.

&&

.LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/...
FRIDAY NIGHT THROUGH THURSDAY...A QUIET BEGINNING AND ENDING OF
THIS PERIOD WITH AN ACTIVE MIDDLE OF THE PERIOD. FAIRLY GOOD
AGREEMENT AMONGST THE MEDIUM RANGE GUIDANCE YIELDS NEAR TO ABOVE
NORMAL FORECAST CONFIDENCE.

FRIDAY NIGHT THROUGH SATURDAY NIGHT...HIGH PRESSURE WILL BUILD INTO
THE REGION FRIDAY NIGHT THROUGH SATURDAY NIGHT. UNDER CLEAR
SKIES...TEMPERATURES WILL FALL INTO THE 40S AT MANY INLAND LOCATIONS
FRIDAY NIGHT...THEN WILL RECOVER INTO THE MID TO UPPER 70S AWAY FROM
THE IMMEDIATE COAST SATURDAY AS HIGH PRESSURE SLIDES OFFSHORE
ALLOWING A MORE SOUTHERLY FLOW TO DEVELOP. AN INCREASE IN CLOUD
COVER WILL BEGIN SATURDAY AFTERNOON AND CONTINUE SAT NIGHT BUT NO
RAIN IS EXPECTED THROUGH SAT NIGHT. TEMPS WILL MOSTLY REMAIN IN THE
50S SAT NIGHT.

SUNDAY...OVERRUNNING MOISTURE AND ASSOCIATED SHOWERS WILL SPREAD
INTO THE REGION FROM SW TO NE...AND AT LEAST ELEVATED INSTABILITY
MAY SUPPORT THUNDER DURING THE AFTERNOON. THE NE EXTENT OF THE
PRECIP IS A BIT UNCERTAIN BUT THINK THE BEST CHANCE WILL REMAIN SW
OF BEAUFORT.

SUNDAY NIGHT...WARM SECTOR MAY SPREAD INTO THE FORECAST AREA...
AHEAD OF AN APPROACHING/STRONG COLD FRONT. GFS
KINEMATIC/THERMODYNAMIC PARAMETERS APPEAR VERY FAVORABLE FOR
SEVERE WEATHER UNTIL FROPA MONDAY MORNING. HOWEVER...ONGOING
CONVECTION SOUTH OF THE REGION MAY LIMIT THE POTENTIAL TO A
GREATER EXTENT THAN SUGGESTED BY THE GFS. GIVEN UNCERTAINTY...TOO
EARLY TO ADVERTISE A SIGNIFICANT SEVERE WEATHER EVENT FOR SUNDAY
NIGHT/EARLY MONDAY...BUT AT LEAST SE GA IS IN THE DAY 4 CONVECTIVE
OUTLOOK FROM SPC.

MONDAY THROUGH THURSDAY...A STRONG COLD FRONT WILL CROSS THE REGION
MONDAY MORNING WITH HIGH PRESSURE HOLDING OFF FROM BUILDING IN UNTIL
AFTER THE LARGE UPPER TROUGH SHIFTS OFFSHORE TUESDAY. TEMPERATURES
WILL BE MUCH MORE OF AN ISSUE AS THEY REMAIN BELOW NORMAL UNTIL
PROBABLY THURSDAY. HIGHS MAY NOT GET OUT OF 50S TUE AND WILL LIKELY
DIP INTO THE 30S TUE AND WED MORNINGS. AGRICULTURAL INTERESTS SHOULD
SHOULD REMAIN ALERT FOR THE POTENTIAL FOR A LATE SEASON FROST/FREEZE
EVENT NEXT WEEK.

LAKE WINDS...THE SURFACE PRESSURE GRADIENT/MIXED LAYER WILL SUPPORT
STRONG WINDS OVER LAKE MOULTRIE MONDAY THROUGH TUESDAY NIGHT...AND A
LAKE WIND ADVISORY WILL LIKELY BE REQUIRED FOR ALL OR PORTIONS OF
THIS PERIOD.

&&

.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
HEAVY RAIN WITH IFR CONDS AND OCNL TSTMS WILL CONTINUE TO DOMINATE
THE TAFS THROUGH THE EARLY MRNG HOURS. HAVE CONTINUED
PREDOMINANTLY IFR CIGS WITH MVFR VSBYS THROUGH EARLY TMRW
MRNG...ALTHOUGH PERIODS OF HEAVY RAIN MAY REDUCE VSBYS TO IFR
LEVELS WHILE SCOURING OUT SOME OF THE LOW LEVEL CLOUDS UP TO MVFR
LEVELS. HEAVY RAIN WILL PERSIST THROUGH AROUND 22Z THIS AFTN THEN
THE PRECIP IS EXPECTED TO LESSEN BETWEEN 22Z-02Z...FOLLOWED BY
ANOTHER ROUND OF HEAVY RAIN/TSTMS AS THE WARM FRONT LIFTS ENTIRELY
N OF THE AREA BY THEN WITH THE COLD FRONT TRAILING THROUGH THE
GULF COAST STATES.

PRECIP SHOULD BE THROUGH BOTH TERMINALS BY THE 08Z-12Z TIMEFRAME
TMRW MORNING FOLLOWED BY THE COLD FRONT SHORTLY THEREAFTER. THAT
WILL ALLOW FOR FAIRLY STEADILY CLEARING SKIES THROUGH THE DAY
TOMORROW...HENCE VFR CONDS.

ANOTHER CONCERN OVERNIGHT THROUGH TMRW MRNG WILL BE WINDS...BOTH
AT THE SFC AND ALOFT. SOME DECOUPLING OVERNIGHT BETWEEN WINDS AT
THE SFC /WHICH WILL BE S-SW AT ARND 10-12 KT/ AND WINDS AT 2 KFT
/WHICH WILL BE SW AT 40-45 KT BETWEEN 04Z-12Z/ WILL LIKELY CREATE
LLWS CONDITIONS STARTING LATE TNGT AND LASTING THROUGH TMRW
MORNING. ONCE MIXING COMMENCES SHORTLY AFTER DAYBREAK...WINDS AT
THE SFC WILL INCREASE FROM THE SW-W TO 15-20 KT.

EXTENDED AVIATION OUTLOOK...VFR CONDITIONS WILL PERSIST INTO
SUNDAY. MVFR OR LOWER CONDITIONS MAY REDEVELOP IN
SHOWERS/THUNDERSTORMS SUNDAY NIGHT AND EARLY MONDAY...WITH VFR
CONDITIONS RETURNING MONDAY AFTERNOON. GUSTY CONDITIONS ARE
EXPECTED MONDAY THROUGH TUESDAY.

&&

.MARINE...
A WARM FRONT WILL LIFT N THROUGH THE WATERS TONIGHT WHILE A COLD
FRONT REMAINS WELL W OF THE WATERS...ALLOWING WINDS TO SHIFT FROM
E TO S THROUGH THE EVENING THEN TO S-SW LATE TONIGHT AND EARLY
TMRW MORNING. WIND SPEEDS WILL STEADILY INCREASE OVER THE WATERS
AS LOW LEVEL JETTING INCREASE AHEAD OF THE COLD FRONT. THIS WILL
PUSH THE SC NEARSHORE WATERS TO SCA WIND SPEEDS DURING THE EARLY
MORNING HOURS. IN ADDITION...SUSTAINED WIND SPEEDS WILL REACH THE
UPPER LIMITS OF SCA CRITERIA IN THE OUTER GA WATERS ALONG WITH A
PERIOD OF TIME DURING THE PRE-DAWN HOURS THROUGH LATE MORNING THAT
FREQUENT GUSTS TO GALE FORCE MAY BE REACHED. FEEL RATHER CONFIDENT
IN THIS SCENARIO SO HAVE OPTED TO RAISE A GALE WARNING FOR AMZ374.
AS FOR THE NEARSHORE GA WATERS...IT WILL BE A BIT BORDERLINE DUE
TO THE JETTING OCCURRING FURTHER OFFSHORE SO WILL CAP WINDS AT 20
KT.

WINDS WILL REMAIN ELEVATED THROUGH THE FIRST HALF OF FRIDAY AS
DEEP MIXING AND SUBSIDENCE ALLOWS STRONG LOW LEVEL WINDS TO MIX TO
THE SFC. WINDS WILL GRADUALLY SETTLE GOING TO THE LATTER HALF OF
THE DAY AS THE PRESSURE GRADIENT SLACKENS AND HIGH PRES STARTS TO
MAKE INROADS TO THE WATERS.

FRIDAY NIGHT THROUGH TUESDAY...IMPROVING CONDS EXPECTED FRI NIGHT AS
HIGH PRES MOVE INTO THE AREA BEHIND A DEPARTING COLD FRONT. AHEAD OF
THE NEXT LOW PRES...S WINDS WILL INCREASE AGAIN SUN..AND SEAS WILL
BUILD IN ACCORDANCE THROUGH SUN NIGHT. SCA CONDITIONS APPEAR LIKELY
SUN NIGHT...AND GALES CANNOT BE RULED OUT...ESPECIALLY ACROSS THE GA
WATERS BEYOND 20 NM FROM SHORE. THEN...WINDS WILL SHIFT TO THE W
AFTER THE COLD FRONT PUSHES OFFSHORE EARLY MON...AND WIDESPREAD SCA
CONDITIONS WILL CONTINUE THROUGH EARLY NEXT WEEK WITH GALES STILL
POSSIBLE...MAINLY OVER THE GA WATERS BEYOND 20 NM FROM SHORE.

&&

.HYDROLOGY...
HAVE ISSUED SEVERAL RIVER FLOOD WARNINGS FOR AREA RIVERS...
INCLUDING THE SANTEE RIVER AT JAMESTOWN...THE CANOOCHEE RIVER NEAR
CLAXTON...THE OGEECHEE RIVER NEAR MIDVILLE AND THE OHOOPEE RIVER
NEAR REIDSVILLE. WITH ADDITIONAL RAINFALL EXPECTED THROUGH THE
REST TONIGHT AND SUN NIGHT INTO MONDAY...ADDITIONAL RIVER RISES
ARE LIKELY AND THE POTENTIAL FOR ADDITIONAL RIVER FLOODING WILL
INCREASE ACROSS THE REGION.

AS FOR THE FLASH FLOOD WATCH...HAVE OPTED TO KEEP THE WATCH GOING
AS IT IS CURRENTLY DELINEATED...MAINLY HIGHLIGHTING SE GA S OF
I-16. HPC HAS MOD RISK OF EXCESSIVE RAINFALL IN THIS AREA...WITH A
SLGT RISK OF EXCESSIVE RAINFALL GOING A BIT FURTHER INTO FAR SRN
