AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
926 AM EDT SUN MAY 17 2009

.SYNOPSIS...
ATLC HIGH PRESSURE WILL GIVE WAY TO A STRONG COLD FRONT WHICH WILL
DROP SOUTHEAST THROUGH THE AREA THIS AFTERNOON INTO THIS EVENING
AND BECOME STATIONARY ACROSS FLORIDA THROUGH THE REMAINDER THE
WEEK. LOW PRESSURE IS EXPECTED TO DEVELOP SOUTH OF THE AREA AND
MAY LINGER THROUGH MUCH OF THE WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
SFC ANALYSIS PUTS A COLD FRONT ENTERING THE WRN CAROLINAS...
EXTENDING SWWD THROUGH NRN GA...CENTRAL AL AND SRN MS. THIS FRONT
WILL CONTINUE TO PROGRESS SE TOWARD THE AREA TDA WHILE A DEEPENING
UPPER LEVEL LONGWAVE TROUGH SHIFTS EWD ACROSS THE OH RIVER VALLEY
THROUGH GULF COAST STATES. AS THE TROUGH DEEPENS...THIS WILL
INTENSIFY LOW AND MID LEVEL JETTING...PUTTING THE CHS CWFA WITHIN
THE INFLUENCE OF A JET STREAK RIGHT ENTRANCE REGION. GIVEN AMPLE
MOISTURE AHEAD OF THE FRONT /PWATS ARND 1.75 INCHES/...DECENT
PREFRONTAL LOW LEVEL CONVERGENCE AND MODEST INSTABILITY...THE
INGREDIENTS ARE AVAILABLE FOR NOT ONLY A HIGH COVERAGE OF
SHWRS/TSTMS BY THIS AFTN BUT ALSO THE POTENTIAL FOR SOME STORMS TO
PRODUCE HEAVY RAIN AND/OR SEVERE WX. SLIGHT ONSHORE FLOW THROUGH
MIDDAY WILL HELP ENHANCE LLVL MOISTURE...CAPE/S INCRS TO ARND 1500
J/KG...DEWPOINTS IN THE MID-UPR 60S AND NO CAP/CINH BY THIS AFTN
SHOULD BE ENOUGH TO PRODUCE CLUSTERS OF STORMS THAT MAY PRODUCE
LARGE HAIL AND/OR DMGG WIND GUSTS. IN ADDITION...THE DEEP MOISTURE
AND HIGH PWATS TRANSLATE TO QPF/S OF 1-2 INCHES ACRS THE AREA WITH
POSSIBLY HIGHER LOCALIZED AMOUNTS. WIDESPREAD FLOODING IS NOT
EXPECTED DUE TO THE LOCALIZED NATURE OF THE CONVECTION...THUS A
FLASH FLOOD WATCH IS NOT WARRANTED BUT WILL CONTINUE MENTION OF
LOCALLY HEAVY RAINFALL IN THE GRIDDED/TEXT FORECASTS AND THE
HAZARDOUS WX OUTLOOK.

VERY FEW CHANGES NEEDED TO THE MAX TEMP SCHEME OF UPR 70S N TO
MID 80S S...THOUGH CLOUD AND RAIN COMPLICATIONS MAY MAKE FOR A FEW
JAGGED JUMPS/DROPS IN THE HOURLY TEMP CURVE.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM MONDAY/...
WIDESPREAD SHOWERS/TSTMS ARE EXPECTED TO BE ONGOING THIS EVE AS A
POTENT COLD FRONT PUSHES THROUGH THE AREA. LOCALLY HEAVY RAINFALL
WILL BE A POSSIBILITY WITH FAVORABLE POSITIONING OF THE RIGHT
ENTRANCE REGION OF THE UPPER JET AND PWATS APPROACHING 2 INCHES
AND WE CONTINUE TO ACCESS THE POTENTIAL FOR FLASH FLOODING. STORM
TOTAL AMOUNTS OF 2-4 INCHES APPEAR LIKELY FOR THE REGION...BUT WE
FEEL THE RISK FOR WIDESPREAD FLASH FLOODING IS NOT HIGH ENOUGH TO
JUSTIFY A FLASH FLOOD WATCH ATTM. THIS WILL BE RE- EVALUATED WITH
LATER FORECAST CYCLES BUT A MENTION OF LOCALLY HEAVY RAINFALL AND
MINOR FLOODING WILL BE INCLUDED IN THE HAZARDOUS WEATHER OUTLOOK.
ANY TSTM ACTIVITY IS EXPECTED TO BECOME INCREASINGLY ELEVATED WITH
TIME AS COOLER/DRIER AIR ADVECTS IN FROM THE NORTH SO WILL HAVE
DECREASING TSTM CHANCES THROUGH THE NIGHT. BREEZY CONDITIONS
APPEAR LIKELY...PARTICULARLY AT THE COAST WHERE WINDS COULD GUST
AS HIGH AS 35 MPH AT TIMES AS COOL/DRY AIR INTERACTS WITH THE WARM
ATLANTIC WATERS.

LOWS WILL RANGE FROM THE LOWER 50S INLAND TO THE MID/UPPER 50S AT
THE COAST...WELL BELOW NORMAL.

&&

.LONG TERM /MONDAY THROUGH SATURDAY/...
ALL MODELS LEAVE ENERGY BEHIND AS TROF EXISTS EAST COAST MONDAY
NIGHT AND INTO TUESDAY. FAIRLY GOOD MODEL CONSENSUS THAT AN UPPER
LEVEL CUTOFF LOW WILL FORM IN THE EASTERN GULF OF MEXICO BY TUESDAY
MORNING WHICH WILL HELP MAINTAIN FAIRLY STRONG NORTH TO NORTHEAST
SURFACE WINDS INTO MID WEEK. GFS AND NAM ARE SLOWER TRYING TO MOVE
DRIER AIR INTO THE AREA MONDAY AND MONDAY NIGHT AND THEN IN RESPONSE
TO DEVELOPING CUTOFF BRING THE DEEP MOISTURE BACK INTO THE AREA
TUESDAY AND TUESDAY NIGHT...WITH THE NAM BY FAR THE MOST AGGRESSIVE.
ECMWF AND GEM BRING SOMEWHAT DRIER AIR MORE QUICKLY INTO THE AREA
AND HOLD OFF UNTIL WEDNESDAY OR WEDNESDAY NIGHT BEFORE BRINING THE
DEEPER MOISTURE BACK. MAINTAINED THE DECREASING CHANCES FOR RAIN
MONDAY AND INTO MONDAY NIGHT AND THEN SLIGHT CHANCE OR CHANCE POPS
ALONG THE COAST CLOSER TO THE DEEPER MOISTURE ON TUESDAY. SLOWLY
INCREASE THE THREAT FOR RAIN AS WELL AS CLOUD COVER TUESDAY NIGHT
INTO THURSDAY AS ALL MODELS CONVERGE ON HAVING DEEPER MOISTURE OVER
THE AREA ALONG WITH RATHER IMPRESSIVE ISENTROPIC LIFT...ESPECIALLY
FOR WEDNESDAY NIGHT AND THURSDAY. KEPT THE THREAT FOR PRECIPITATION
IN THE CHANCE CATEGORY FOR NOW FOR WEDNESDAY NIGHT AND
THURSDAY...HOWEVER IF MODEL TRENDS CONTINUE...THE THREAT FOR RAIN
WILL NEED TO BE INCREASES. IT IS POSSIBLE THAT THERE COULD BE A
SIGNIFICANT RAIN EVENT WEDNESDAY NIGHT AND THURSDAY. IN
ADDITION...THERE ARE INDICATION THAT FAIRLY STRONG ONSHORE WINDS
WILL OCCUR IN THE MID WEEK TIME FRAME ALONG THE COAST. MADE NO
SIGNIFICANT CHANGES TO THE FORECAST BEYOND THURSDAY...ALTHOUGH POPS
MAY NEED TO BE RAISED BY LATER SHIFTS FOR THE LATER PART OF THE WEEK
AS DEEP SOUTHEASTERLY FLOW IS EXPECTED TO CONTINUE INTO THE
WEEKEND.

&&

.AVIATION /13Z SUNDAY THROUGH THURSDAY/...
CLOUDS WILL INCREASE FROM THE W WITHIN DEEP MOISTURE AS A STRONG
COLD FRONT SLOWLY APPROACHES THE AREA. CONVECTIVE RAINS CAN BE
EXPECTED BY EARLY-MID AFTN...GRADUALLY GROWING IN STRENGTH AND
INTENSITY AND POCKETS OF HEAVY RAINFALL ARE LIKELY. HAVE CARRIED
CB GROUPS WITH MVFR CIGS AT BOTH TERMINALS...THOUGH HEAVY RAIN
COULD DROP VSBYS TO IFR LEVELS AT TIMES. THE TSTM POTENTIAL WILL
END FIRST AT KCHS AS THE FRONT PUSHES SE THROUGH THE AREA...WITH
LOCALLY HEAVY STRATIFORM RAIN WITH IFR CIGS EXPECTED THEREAFTER.
WINDS WILL PICK UP OUT OF THE N/NE BEHIND THE FRONT.

EXTENDED AVIATION OUTLOOK...MVFR OR LOWER CONDITIONS ARE EXPECTED
INTO MONDAY AS A COLD FRONT WITH SHOWERS/TSTMS AFFECTS THE AREA.
STRONG N/NE WINDS WILL AFFECT BOTH TERMS THROUGH MID WEEK.

&&

.MARINE...
VERY FEW CHANGES NEEDED TO THE ONGOING MARINE FCST AND WILL RUN
WITH HEADLINES AS THEY ARE CURRENTLY DELINEATED. A COLD FRONT
WILL APPROACH FROM THE W TDA ALLOWING FOR A SLOWLY TIGHTENING
PRESSURE GRADIENT DURING THE AFTN HOURS. HOWEVER...CONDITIONS LOOK
TO REMAIN BELOW SCA LEVELS THROUGH THIS AFTN.

TONIGHT...CONDS DETERIORATE QUICKLY BEHIND THE FRONT TONIGHT WITH
SCA CONDS EXPECTED ALL WATERS. THINK GALES WILL HOLD OFF FOR
MUCH...IF NOT ALL...OF THE NIGHT SO HAVE PUSHED BACK THE GALE
WATCH TO MON.

MONDAY THROUGH THURSDAY...FAIRLY SIGNIFICANT MARINE IS EVENT IS
ANTICIPATED FOR THE MONDAY THROUGH AT LEAST TUESDAY NIGHT TIME
FRAME. NORTH TO NORTHEAST WINDS OF 25 TO 35 KNOTS WITH HIGHER
GUSTS SHOULD DEVELOP ACROSS THE COASTAL WATERS ON MONDAY AND
PERSIST INTO EARLY TUESDAY BEFORE BACKING OFF JUST A LITTLE
TUESDAY NIGHT AS THE WINDS BECOME MORE EASTERLY. SEAS ARE EXPECTED
TO INCREASE TO NEAR 14 FEET IN AMZ374 WITH SEAS POSSIBLY
APPROACHING 9 OR 10 FEET WITHIN THE NEARSHORE WATERS. A GALE WATCH
HAS BEEN MAINTAINED FOR THIS TIME FRAME.

THERE IS GROWING CONCERN THAT POSSIBLY A SECOND GALE EVENT COULD
OCCUR IN THE WEDNESDAY TO THURSDAY TIME FRAME AS A STRONG SURFACE
LOW ASSOCIATED WITH AN UPPER LOW IN THE EASTERN GULF OF MEXICO
TIGHTENS THE PRESSURE GRADIENT ACROSS THE WATERS.

RIP CURRENTS...STRONG NORTHEAST WINDS COUPLED WITH INCREASING WIND
WAVES AND EAST TO NORTHEAST SWELL WILL YIELD AN ENHANCED RISK FOR
RIP CURRENTS FOR MUCH OF THE UPCOMING WEEK. A MODERATE TO HIGH RIP
CURRENT RISK WILL BE LIKELY FOR MOST BEACHES FOR MONDAY THROUGH AT
LEAST WEDNESDAY.

&&

.TIDES/COASTAL FLOODING...
BEACH EROSION AND MINOR COASTAL FLOODING COULD BECOME A CONCERN ON
MONDAY AND TUESDAY AS STRONG NORTH TO NORTHEAST WINDS COMBINE WITH
BUILDING SEAS. CURRENT DATA SUGGESTS WAVES IN THE SURF ZONE COULD
REACH 3-4 FT ON MONDAY AND 4 TO 6 FEET TUESDAY AND WEDNESDAY AND A
HIGH SURF ADVISORY MAY EVENTUALLY BE NEEDED. IN ADDITION...TIDES ARE
EXPECTED TO RUN 1-2 FT ABOVE PREDICTED LEVELS ON WEDNESDAY WHICH
COMBINED WITH ANY LOCALLY HEAVY RAINS COULD PUSH TIDE LEVELS INTO
COASTAL FLOOD ADVISORY CRITERIA.

&&

.CHS WATCHES/WARNINGS/ADVISORIES...
GA...NONE.
SC...LAKE WIND ADVISORY FROM MIDNIGHT TONIGHT TO 8 PM EDT TUESDAY
     FOR SCZ045.
MARINE...GALE WATCH FROM MONDAY MORNING THROUGH TUESDAY AFTERNOON FOR
     AMZ352-354-374.
     SMALL CRAFT ADVISORY FROM MIDNIGHT TONIGHT TO 8 AM EDT MONDAY
     FOR AMZ330-350-352-354-374.
     GALE WATCH FROM MONDAY MORNING THROUGH TUESDAY MORNING FOR
