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

.SYNOPSIS...
A NEARLY STATIONARY FRONT WAVERING OVER SOUTHERN GEORGIA THROUGH
THIS AFTERNOON WILL LIFT N AS A WARM FRONT 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 LATE
TONIGHT. 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.
ANOTHER COLD FRONT WILL CROSS THE REGION TUESDAY. HIGH PRESSURE
WILL THEN BUILD INTO THE REGION THROUGH MIDWEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
SFC ANALYSIS SHOWS THE QUASI-STATIONARY WAVY FRONT SNAKING THROUGH
SRN GA/AL BACK TO A POTENT LOW PRES CENTER OVER THE ARLATEX AREA.
ITS ASSOCIATED COLD FRONT IS PUSHING THROUGH THE LOWER MISS RIVER
VALLEY. STRONG E AND S LOW LEVEL FLOW...BRINGING IN BOTH ATLC
MOISTURE N OF THE STALLED FRONT AND GULF MOISTURE S OF THE
FRONT...IS BEING CONCENTRATED NEAR THE FRONT TO PROLONG WIDESPREAD
MOD/HVY RAIN ACRS THE AREA. IN ADDITION...ELEVATED INSTABILITY IS
CONTRIBUTING TO A FEW EMBEDDED ISOLD TSTMS ACRS THE AREA. LOCAL
MEDIA HAVE REPORTED 1.5-2.0 INCHES OF RAIN THUS FAR TDA ACRS THE
CHARLESTON TRI-COUNTY AREA AND THESE TOTALS LIKELY EXTEND SWD
THROUGH MUCH OF SRN SC. WAVES OF LOW PRES WILL RIDE ALONG THE
STALLED FRONT WHICH WILL CONTRIBUTE TO ENHANCED RAINFALL THROUGH
LATE MRNG. HPC HAS INCREASED THE EXCESSIVE RAINFALL POTENTIAL FOR
SOUTHEAST GEORGIA INTO THE MODERATE RANGE...WHILE SPREADING THE
SLIGHT CHANCE FURTHER NORTH INTO THE FORECAST AREA. HAVE THUS
MAINTAINED ONGOING FLASH FLOOD WATCH AND MENTIONED CATEGORICAL
HEAVY RAIN CHANCES FOR BOTH GEORGIA AND SOUTH CAROLINA ZONES
TODAY.

PER SREF/WRF/NAM DEPICTIONS...THERE WILL BE SOME DISSIPATING OF
THE PRECIP COVERAGE GOING INTO THE AFTN HOURS. IN ADDITION... NAM
AND GFS BOTH KEEP BEST INSTABILITY S OF THE AREA THROUGH THE DAY
WHICH CONTINUES TO HINT THAT THE FRONT WILL REMAIN STALLED S OF
THE AREA THROUGH MOST OF THE DAY. AM STILL MENTIONING CHC THUNDER
BUT BEST CHCS FOR TSTMS LOOK TO BE CONFINED TO JUST AFTER THE
DAYTIME PERIOD.

OVERALL...NOT TOO MANY CHANGES MADE TO THE NEAR TERM FORECAST AS
IT WILL PRIMARILY BE DRIVEN BY RADAR TRENDS.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM FRIDAY/...
THERE REMAINS MANY QUESTIONS REGARDING SEVERE THUNDERSTORM POTENTIAL
TONIGHT ASSOCIATED WITH THE WAVERING WARM FRONT AND THE APPROACHING
COLD FRONT TO THE WEST. GFS CONFINES HIGHEST INSTABILITY SOUTH OF
THE AREA...WITH THE WARM FRONT UNABLE TO LIFT COMPLETELY THROUGH
THE FORECAST AREA BEFORE THE COLD FRONT PUSHES OFFSHORE TONIGHT.
NAM FOLLOWS A SIMILAR PATTERN DURING THE DAYTIME HOURS...BUT
INCREASES INSTABILITY ACROSS THE AREA JUST AHEAD OF THE COLD FRONT
AFTER MIDNIGHT.

THE MAIN LIMITING FACTOR FOR SEVERE DEVELOPMENT IS A DRY SLOT THAT
SHIFTS INTO THE REGION TONIGHT JUST AHEAD OF THE COLD FRONT...
CAUSING PRECIPITATION CHANCES TO DECREASE RAPIDLY DURING THE
SAME PERIOD THAT NAM INDICATES INCREASING INSTABILITY. SEEN IN
BOTH THE NAM AND GFS SOLUTIONS...THIS PUSH OF DRIER AIR LOWERS
CONFIDENCE IN A SIGNIFICANT SEVERE EVENT OVERNIGHT. HOWEVER...IF
THE LINGERING WARM FRONT CAN LIFT NORTHWARD...IT WILL BE ABLE TO
INCREASE DEWPOINTS FROM THE SOUTH AND ENHANCE INSTABILITY AND
CONVERGENCE AT THE SAME TIME THAT A NEGATIVELY TILTED UPPER TROUGH
APPROACHES FROM THE NORTHWEST. SPC DOES REMAIN IMPRESSED WITH THE
POTENTIAL FOR SEVERE...AND HAS THEREBY INCREASED THE RISK TO
MODERATE ACROSS FAR SOUTHEAST GEORGIA COUNTIES.

TO RECONCILE...HAVE MADE SOME MODIFICATIONS TO THE THUNDERSTORM
FORECAST TO ACCOUNT FOR LATEST MODEL TRENDS...WHILE STILL
CONSIDERING THE POTENTIAL IF MODEL SOLUTIONS ARE OFF THE MARK.
AFTER 00Z...HAVE INCREASED TO A CHANCE OF THUNDER WITHIN LIKELY
SHOWER ACTIVITY FOR SOUTH CAROLINA COUNTIES AND FAR INLAND GEORGIA
COUNTIES. HAVE ALSO MAINTAINED SEVERE WORDING IN THE FORECAST FOR
LOCATIONS MAINLY SOUTH OF INTERSTATE 16 IN SOUTHEAST
GEORGIA...WHERE INSTABILITY WILL BE HIGHEST IF THE WARM FRONT DOES
INDEED PULL NORTH. HAVE THEN DROPPED SEVERE WORDING OUT OF THE
FORECAST AFTER 06Z...WHILE ALSO DECREASING POPS DOWN TO 30 TO 40
PERCENT...AS THIS IS WHEN BOTH MODELS INDICATE THE SLOT OF DRY AIR
SHIFTING INTO THE AREA.

&&

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
THE COLD FRONT AND ANY RESIDUAL MOISTURE/PRECIPITATION SHOULD BE
PULLING AWAY FROM THE REGION EARLY FRIDAY. EXPECT DRIER...BREEZY
AND WARM DAY WITH TEMPERATURES RECOVERING TO AROUND 80F.

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.
ALSO...SATURDAY WILL START SUNNY...THEN HIGH CLOUDS WILL OVERSPREAD
THE REGION DURING THE AFTERNOON. THEN...MID/HIGH LEVEL CLOUDS WILL
THICKEN SATURDAY NIGHT...HOLDING LOW IN THE 50S.

SUNDAY...OVERRUNNING MOISTURE AND ASSOCIATED SHOWERS WILL SPREAD
INTO THE REGION FROM W/SW TO E/NE...AND AT LEAST ELEVATED
INSTABILITY MAY SUPPORT THUNDER DURING THE AFTERNOON. TIMING/POPS
REMAIN SOMEWHAT UNCERTAIN...AND ADJUSTMENTS TO THIS FORECAST WILL
LIKELY BE REQUIRED OVER THE NEXT FEW DAYS.

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.

A STRONG COLD FRONT WILL CROSS THE REGION MONDAY...THEN MEDIUM
RANGE GUIDANCE SUGGESTS THAT A STRONG SHORTWAVE WILL DRIVE A
SECONDARY COLD FRONT THROUGH THE AREA TUESDAY...CARVING OUT AN
IMPRESSIVE LONGWAVE UPPER TROUGH OVER THE EASTERN US AND
SUPPORTING MUCH BELOW NORMAL TEMPERATURES THROUGH WEDNESDAY. 0Z
GFS MOS GUIDANCE FORECASTS TEMPERATURES AT 15F BELOW NORMAL FOR
THIS TIME OF YEAR...WITH LOWS WELL INTO THE 30S MONDAY AND TUESDAY
NIGHTS. 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 FRIDAY...AND A LAKE WIND
ADVISORY WILL LIKELY BE REQUIRED. AS MIXING PERSISTS INTO FRIDAY
EVENING...STRONG WINDS MAY CONTINUE...THEN WINDS SHOULD DIMINISH
OVERNIGHT.

&&

.AVIATION /18Z 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...PERIODS OF MVFR OR LOWER CONDITIONS
ARE POSSIBLE IN SHOWERS/THUNDERSTORMS INTO EARLY FRIDAY. VFR
CONDITIONS RETURN FRIDAY NIGHT AND PERSIST INTO SUNDAY. MVFR OR
LOWER CONDITIONS MAY REDEVELOP IN SHOWERS/THUNDERSTORMS SUNDAY
NIGHT AND EARLY MONDAY...WITH VFR CONDITIONS RETURNING MONDAY
AFTERNOON.

&&

.MARINE...
VERY FEW CHANGES MADE TO ONGOING MARINE FCST THINKING AND WILL
MAINTAIN SCA HEADLINES AS THEY ARE CURRENTLY DELINEATED.

A RATHER VARIABLE WIND REGIME WILL PREVAIL THROUGH MOST OF
TODAY...WHILE A WARM FRONT REMAINS SOUTH OF THE AREA. WAVES OF LOW
PRESSURE WILL RIDE EAST- NORTHEAST ALONG THE STALLED FRONT AND
CROSS FROM THE GULF OF MEXICO OFF THE SOUTHEAST COAST THROUGH THE
DAY. WINDS WILL BECOME SOLIDLY SOUTH AND INCREASE TONIGHT...AS THE
MAIN WAVE OF LOW PRESSURE SHIFTS OFF TO THE NORTHEAST AND A COLD
FRONT APPROACHES FROM THE WEST. HAVE GONE AHEAD AND ISSUED A SMALL
CRAFT ADVISORY FOR THE SOUTH CAROLINA WATERS NORTH OF EDISTO AND
THE OFFSHORE GEORGIA MARINE ZONES.

IN THE WAKE OF COLD FROPA...THE TIGHT SURFACE PRESSURE GRADIENT
AND A WELL MIXED BOUNDARY LAYER OVER LAND AREAS ALONG THE COAST
WILL SUPPORT SMALL CRAFT ADVISORY CONDITIONS ACROSS ALL COASTAL
WATERS...INCLUDING CHARLESTON HARBOR. AN UNSTABLE MARINE BOUNDARY
LAYER MAY THEN CONTINUE TO SUPPORT SCA CONDITIONS...MAINLY OUTSIDE
THE HARBOR...INTO FRIDAY NIGHT. WINDS WILL DIMINISH AND SEAS WILL
SUBSIDE AS HIGH PRESSURE SHIFTS OVER THE WATERS LATE FRIDAY NIGHT
THROUGH EARLY SUNDAY. THEN...AHEAD OF THE NEXT LOW PRESSURE...S
WINDS WILL AGAIN INCREASE..AND SEAS WILL BUILD SUNDAY PM THROUGH
SUNDAY NIGHT. SCA CONDITIONS APPEAR LIKELY...AND LOCAL GALE
CONDITIONS CANNOT BE RULED OUT. THEN...WINDS WILL SHIFT TO THE
WEST AFTER COLD FRONT MONDAY...AND AT LEAST WIDESPREAD SCA
CONDITIONS WILL CONTINUE INTO EARLY NEXT WEEK.

&&

.HYDROLOGY...
DUE TO RECENT AND ONGOING RAINFALL...AREA RIVER LEVELS CONTINUE TO
RISE...ALREADY PROMPTING A RIVER FLOOD WARNING ON THE SOUTH SANTEE
RIVER AT JAMESTOWN. GIVEN THE POTENTIAL FOR PERIODS OF SIGNIFICANT
RAINFALL THIS WEEK AND AGAIN LATE NEXT WEEKEND/EARLY NEXT WEEK...
ADDITIONAL RIVER RISES APPEAR LIKELY...AND THE POTENTIAL FOR
ADDITIONAL RIVER FLOODING WILL INCREASE ACROSS THE REGION.

&&

.CHS WATCHES/WARNINGS/ADVISORIES...
GA...FLASH FLOOD WATCH THROUGH FRIDAY MORNING FOR GAZ114>119-
