AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
413 PM EDT SAT MAY 10 2008

.SYNOPSIS...
A BACKDOOR FRONT WILL DROP SOUTH INTO THE AREA TONIGHT THEN LIFT
NORTH ON SUNDAY. A STRONG COLD FRONT WILL CROSS THE AREA SUNDAY
EVENING FOLLOWED BY HIGH PRESSURE. ANOTHER FRONT MAY AFFECT THE
AREA EARLY NEXT WEEKEND.

&&

.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
TORNADO WATCH IN EFFECT UNTIL 9 PM FOR THE ENTIRE FORECAST AREA.
ATMOSPHERE HAS BEEN STRONGLY CAPPED FOR MUCH OF THE DAY...ALLOWING
POTENTIAL INSTABILITY TO INCREASE DRASTICALLY. HOWEVER...WITH THE
APPROACH OF SHORTWAVE TROUGHING FROM THE W...COOLER MID-LEVELS ARE
YIELDING A WEAKENING CAP ACROSS THE WESTERN PORTION AS WELL AS
PROVIDING A FORCING MECHANISM FOR CONVECTIVE INITIATION. WITH THE
BREAKING CAP...EXPLOSIVE CONVECTIVE GROWTH IS POSSIBLE WHERE
PARCELS CAN BREAK THROUGH. THIS PROMPTED A TORNADO WATCH FOR THE
ENTIRE AREA UNTIL 9 PM. A SEABREEZE IS TRYING TO DEVELOP ALONG THE
SC COAST BUT FAIRLY STRONG CAP THAT REMAINS OVER EASTERN SC SHOULD
LIMIT THE ABILITY OF THE SEABREEZE TO KICK OFF ITS OWN CONVECTION.
THUS THE BEST COVERAGE OF SHOWERS AND STORMS THROUGH EARLY EVENING
SHOULD BE SOUTHEAST GA AND EXTREME SOUTHERN SC. WILL FEATURE THE
HIGHEST POPS IN THIS AREA.

OVERNIGHT TONIGHT...MODELS /ESPECIALLY THE NAM/ SHOW ANOTHER
STRONG VORT MAX MOVING INTO SOUTHERN SC AFTER 06Z. THE BACKDOOR
COLD FRONT WILL BE DROPPING TO NEAR THE SAVANNAH RIVER DURING THIS
TIME...PLACING A SHALLOW STABLE LAYER OVER MUCH OF SOUTHERN SC.
THE MID-LEVELS WILL REMAIN STOKED EVEN N OF THE BOUNDARY THUS
ELEVATED CONVECTION WILL BE A POSSIBILITY WITH HAIL THE PRIMARY
THREAT. S OF THE BOUNDARY HAIL AND WIND DAMAGE WILL BE POSSIBLE
WITH ANY STORMS...WITH ISOLATED TORNADOES BECOMING INCREASINGLY
LIKELY LATE TONIGHT AS THE WARM FRONT PROVIDES INCREASING LOW-
LEVEL HELICITY. HAVE SHOWN SOME LIKELY POPS OVERNIGHT ACROSS THE
CENTRAL PART OF THE AREA DUE TO INCREASING ISENTROPIC
LIFT...CONVECTIVE FORCING AND BOUNDARY INTERACTIONS. WILL MAINTAIN
POSSIBLY SEVERE WORDING IN GRIDS THROUGH TONIGHT.

&&

.SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/...
ONE OR TWO ADDITIONAL ROUNDS OF SEVERE WEATHER ARE LIKELY ON
SUNDAY...WITH THE POSSIBILITY OF LONG TRACK TORNADOES IN SOME
LOCATIONS. THE LATEST SPC FORECAST INCLUDES A MODERATE RISK OF
SEVERE WEATHER WITH 45 PERCENT PROBABILITIES ENCOMPASSES THE ENTIRE
FORECAST AREA.

THE FIRST ROUND OF ACTIVITY LOOKS TO BE DURING THE MORNING HOURS
NEAR AND SOUTH OF THE WARM FRONT...WITH EVEN ELEVATED CONVECTION N
OF THE FRONT. THIS IS AIDED BY SHORT WAVE MOVING THROUGH DURING THE
15-18Z TIME FRAME WHILE LOW LEVEL JET OF 40-50 KT SHIFTS THROUGH THE
FORECAST AREA. HELICITY VALUES ARE 250-350 M2/SEC2 DURING THE
MORNING HOURS...WHILE EHI IS BETWEEN 2 AND 3 WITH HIGHEST VALUES
NEAR AND ALONG THE FRONT IN SC. TORNADIC ACTIVITY IS CERTAINLY
POSSIBLE WITH SUCH AN ATMOSPHERE...WHILE SIGNIFICANT RIGHT TURNING
HODOGRAPHS ARE REALIZED. THE BETTER CHANCES OF TORNADOES WILL OCCUR
IN SRN SC WHICH IS CLOSER TO THE FRONTAL BOUNDARY.

ADDITIONAL SEVERE WEATHER LOOKS TO OCCUR AGAIN IN THE AFTN AHEAD OF
THE COLD FRONT...AS A SQUALL LINE MOVES IN FROM THE W-NW. IT IS
DURING THIS TIME THAT THE LEFT FRONT QUAD OF THE UPPER LEVEL JET
WITH WIND SPEEDS IN EXCESS OF 120 KT MOVES INTO THE REGION. CAPE
VALUES WITH MAX TEMPS WELL INTO THE 80S AND DEWPTS WELL INTO THE 60S
TO NEAR 70 CLIMB TO OVER 2000 J/KG. AS MID LEVEL LAPSE RATES
INCREASE TO ALMOST 7 DEGREES CELSIUS AND LI/S ARE NEAR -7...SUFFICE
TO SAY THAT ANOTHER ROUND OF SEVERE WEATHER COULD OCCUR. WHILE THE
MAIN RISK WITH THE SQUALL LINE WILL BE DAMAGING WINDS AND LARGE
HAIL...EHI VALUES ARE STILL NEAR 2 OR 3 AND HELICITY IS AS MUCH AS
200-300 M2/S2. ADDITIONALLY RIGHT TURNING HODOGRAPHS ARE AGAIN
OBSERVED. THUS...ISOLATED TORNADOES ARE ONCE AGAIN POSSIBLE.

HAVE INCLUDED MENTION OF TORNADOES...DAMAGING WINDS AND LARGE HAIL
IN THE PUBLIC FORECAST AS WELL AS THE GRIDS.

FRONT TO MOVE THROUGH THE AREA BY 00Z-03Z MONDAY WHICH WILL SHUT OFF
CONVECTION AND THEN MUCH COOLER CONDITIONS WILL MOVE IN BY MONDAY
MORNING.

VERY IMPRESSIVE WIND FIELDS ACROSS THE AREA LATE SUNDAY WITH
GEOSTROPHIC WINDS OF 50 KT OR GREATER...WHILE 925 MB WINDS ARE 35-40
KT. WHILE NOT ALL OF THIS WILL MIX DOWN DUE TO THE CLOUD COVER...IT
LOOKS TO BE ENOUGH FOR WINDS OF AT LEAST 15-30 MPH ACROSS LAND AREAS
SUNDAY. WITH A SLIGHT ONSHORE FETCH OVER COASTAL SC COUNTIES IN THE
LATE AFTN/EVENING...THIS ADDITIONAL FLOW SHOULD BE ENOUGH TO ALLOW
FOR SUSTAINED WINDS TO REACH PAST 30 MPH FROM CHARLESTON TO BEAUFORT
COUNTY. THUS WE HAVE STARTED A WIND ADVISORY FOR THESE 3 COUNTIES.
THE ADVISORY MAY NEED TO BE EXPANDED IN AREAL COVERAGE AND/OR
EXTENDED IN TIME INTO MONDAY AS FIRST COLD AIR ADVECTION/STRONG PRES
RISES DEVELOP SUNDAY NIGHT...THEN AS DEEP MIXING TAKES HOLD ON
MONDAY.

LAKE WINDS...ALTHOUGH THERE IS A LITTLE UNCERTAINTY REGARDING THE
START TIME OF WINDS REACHING 20 KT OR GREATER ACROSS LAKE MOULTRIE
ON SUNDAY...THE POTENTIAL IS CERTAINLY THERE FOR FREQUENT WIND GUSTS
PAST 20 KT IN THE AFTERNOON. THUS WE HAVE INITIATED A LAKE WIND
ADVISORY LATE IN THE DAY. AS COLD AIR ADVECTION RESULTS IN WAKE OF
THE COLD FRONT SUNDAY NIGHT AND GOOD MIXING DEVELOPS MONDAY...THE
LAKE WIND ADVISORY WILL GO THROUGH LATE MONDAY AFTN.

&&

.LONG TERM /MONDAY THROUGH SATURDAY/...
A COLD FRONT ASSOCIATED WITH A LOW PRESSURE SYSTEM WILL CONTINUE TO
PUSH OFFSHORE OVER THE ATLANTIC ON MONDAY. A STRONG NORTHWEST
GRADIENT WIND WILL CONTINUE BEHIND THE COLD FRONT ALLOWING FOR GUSTY
WIND CONDITIONS BETWEEN 15 TO 25 MPH AS STRONG CAA PUSHES INTO THE
REGION DURING THE DAY. ALTHOUGH DRY CONDITIONS WILL CLEAR OUT
SKIES....COOL NORTHWEST WINDS WILL LIMIT HIGH TEMPS IN THE UPPER 70S
OVER PORTIONS OF SC AND AROUND 80 OVER GA. CONDITIONS WILL IMPROVE
MONDAY EVENING AS THE SYSTEM CONTINUES TO SHIFT EAST FURTHER
OFFSHORE ALLOWING THE PRESSURE GRADIENT TO WEAKEN.

HIGH PRESSURE WILL THEN SETTLE INTO THE CAROLINAS MONDAY NIGHT
LEADING TO RATHER DRY CONDITIONS FOR THE NEXT FEW DAYS. EXPECT TEMPS
TO RANGE FROM THE LOW 80S FOR HIGHS AND UNSEASONABLY COOL TEMPS
AROUND 50 FOR LOWS AS A PERSISTENT NORTHWEST FLOW CONTINUES.
CONDITIONS WILL BEGIN TO WARM A FEW DEGREES TUESDAY THROUGH THURSDAY
AS A NEW SYSTEM DEVELOPS OVER THE SOUTH CENTRAL USA. TEMPS ARE
ANTICIPATED TO REACH THE MID 80S BEFORE THIS LOW PRESSURE SYSTEM
AFFECTS THE CAROLINAS.

THE NEXT CHANCE OF PRECIP WILL OCCUR AS THIS NEW SYSTEM DEVELOPS
OVER SOUTH CENTRAL USA THURSDAY WITH A WARM FRONT EXTENDED TOWARDS
THE ATLANTIC COAST. A FEW SHOWERS AND THUNDERSTORMS WILL OCCUR OVER
THE AREA AS THIS FRONT SHIFTS NORTH THROUGH THE CWA. AS THE SYSTEM
PROGRESSES EAST...A COLD FRONT IS EXPECTED TO PUSH THROUGH SOUTHEAST
SC AND GA FRIDAY NIGHT INTO SATURDAY MORNING. AS FROPA OCCURS...
SCATTERED SHOWERS AND THUNDERSTORMS ARE POSSIBLE. HIGH PRESSURE WILL
THEN FILTER INTO THE REGION ONCE AGAIN FOR SUNDAY AS CONDITIONS
BEGIN TO DRY OUT. TEMPS WILL THEN RETURN TO A FEW DEGREES BELOW
CLIMATOLOGY...AROUND 80 FOR HIGHS AND MID 50S FOR LOWS.

&&

.AVIATION /20Z SATURDAY THROUGH THURSDAY/...
MOISTURE AXIS EXTENDING ACROSS MUCH OF GA WILL SERVE AS THE FOCUS
FOR TSTM DEVELOPMENT THIS AFTERNOON...ESPECIALLY LATE AFTERNOON
INTO THE EVENING AS AN UPPER SHORTWAVE MOVES IN FROM THE W. THE
COMBINATION OF SEVERAL PARAMETERS DURING THE EARLY EVENING TIME-
FRAME BODES WELL FOR SAV TERMINAL TO SEE SCT TSTMS. HAVE INCLUDED
TEMPO FOR THIS. TOO DIFFICULT TO PIN DOWN ANY DISCRETE CONVECTION
AROUND CHS TERMINAL THROUGH TONIGHT SO HAVE SIMPLY MAINTAINED CB
IN CEILING GROUP. BACKDOOR FRONT WILL DROP INTO THE AREA OVERNIGHT
WITH LIFT INCREASING ALONG IT. WILL LIKELY SEE MVFR CEILINGS BY
MORNING AT BOTH SITES. MVFR CONDITIONS MAY CONTINUE INTO THE LATE
MORNING AT SAV DUE TO SIGNIFICANT CONVECTIVE DEBRIS REMAINING IN
THE VICINITY.

WITH THE APPROACH OF A SURFACE COLD FRONT AND EMBEDDED LOW
PRESSURE AREAS...COVERAGE OF SHOWERS AND TSTMS WILL INCREASE
DURING THE DAY SUNDAY. SIGNIFICANT SEVERE WX EVENT STILL LOOKS
POSSIBLE. HAVE INCLUDED VICINITY TS AT BOTH TERMINALS FOR THE
FIRST HALF OF SUNDAY. CEILINGS WILL PROBABLY LIFT INTO VFR RANGE
DURING THE MORNING AS THE FRONTAL BOUNDARY LIFTS N AND ENTIRE
REGION FALLS IN WARM SECTOR. GUSTY WINDS EXPECTED...ESPECIALLY
FROM LATE MORNING ONWARD. GUSTS TO 30 KT NOT OUT OF THE QUESTION.

EXTENDED AVIATION OUTLOOK...IFR CIGS/VSBYS MAY IMPACT THE
TERMINALS SUN AFTERNOON IN SHOWERS/STORMS. GUSTY WINDS EXPECTED
ALL DAY SUN INTO SUN NIGHT AHEAD OF A COLD FRONT. VFR MON THROUGH
THU.

&&

.MARINE...
WINDS AND SEAS HAVE REMAINED IN CHECK TODAY DUE TO FAIRLY WEAK
PRESSURE GRADIENT OVER THE WATERS. MAIN CONCERN TONIGHT WILL BE AN
INCREASINGLY PINCHED PRESSURE GRADIENT OVER FAR NORTHERN PORTION
OF SC NEARSHORE WATERS AS A BACKDOOR FRONT DROPS SOUTH. HAVE WINDS
INCREASING BRIEFLY TO 20 KT FAR N LATE TONIGHT WITH THE SOUTHERN
SC NEARSHORE LEG EXPERIENCING VARIABLE WINDS LESS THAN 15 KT.

FRONTAL BOUNDARY WILL BE FOUND ACROSS THE FAR SRN SC WATERS AROUND
DAYBREAK SUNDAY...THEN WILL LIFT BACK N AS A WARM FRONT QUICKLY
THROUGHOUT THE MORNING...REACHING N OF THE MARINE AREA BY AFTN.
WINDS N OF THE FRONT WILL BE E-NE...BUT WILL QUICKLY VEER TO S-SW BY
AFTN...WHILE THE SRN WATERS WILL REMAIN SWLY THROUGH THE MORNING
HOURS. AS LOW LEVEL JET MOVES INTO THE AREA AND PINCHING OF THE PRES
GRADIENT DEVELOPS...GEOSTROPHIC WINDS AT 1000 MB INCREASE TO 50 KT
OR GREATER. GRANTED MUCH OF THAT WILL BE OFFSET BY THE WARM OCEAN
WATERS...BUT CERTAINLY THERE IS ENOUGH FOR SCA/S TO BECOME NECESSARY
BY LATE MORNING FOR ALL OF THE MARINE AREA. WHILE THE SCA/S EASILY
WILL PERSIST INTO SUNDAY NIGHT/MONDAY...CONFIDENCE IS HIGH ENOUGH TO
RAISE A GALE WATCH FOR ALL WATERS FROM LATE SUNDAY INTO EARLY MONDAY
AS 1000 MB GEOSTROPHIC WINDS REMAIN AT LEAST 40 KT...AND COLD AIR
ADVECTION WILL DEVELOP IN WAKE OF COLD FRONT MOVING THROUGH EARLY
SUNDAY NIGHT. THAT ALONG WITH STEADY PRES RISES COULD RESULT IN AT
LEAST WIND GUSTS FREQUENTLY REACHING 35 OR 40 KT. THE WATCH MAY NEED
TO BE UPGRADED TO A GALE WARNING SUNDAY MORNING. SEAS WILL QUICKLY
RESPOND TO THE INCREASING WINDS AND LOOK TO REACH 6 OR 7 FT WITHIN
20 NM OF THE COAST BY LATE SUNDAY OR SUNDAY NIGHT...AND AS HIGH AS 8
OR 9 FT FURTHER OFFSHORE. THE FETCH IN WAKE OF THE FRONT SUNDAY
NIGHT WILL LIMIT SEAS NEAR THE IMMEDIATE COAST...BUT VERY ROUGH
CONDITIONS NONETHELESS WILL STILL PREVAIL ACROSS THE MARINE AREA.
MARINERS ARE STRONGLY URGED TO KEEP ABREAST OF THE LATEST MARINE
FORECASTS...ESPECIALLY SINCE SEVERE WEATHER IS ALSO POSSIBLE THROUGH
SUNDAY.

RIP CURRENTS...ALTHOUGH THE FLOW WILL BE MAINLY OFFSHORE
SUNDAY...THERE MAY BE ENOUGH BACKING TO RESULT IN OCNL SLIGHT
ONSHORE COMPONENT ALONG THE SC BEACHES. THAT ALONG WITH INCREASING
WINDS TO BETWEEN 20 AND 30 MPH WILL RESULT IN A MODERATE RISK OF RIP
CURRENTS...ESPECIALLY IF THERE IS ANY SMALL SWELL ACTIVITY. ALTHOUGH
OUR LOCAL RIP CURRENT WORKSHEET RESULTS IN A LOW RISK FOR THE GA
BEACHES SUNDAY...PREFER TO GO MODERATE THERE AS WELL GIVEN THE
STRONG WIND FIELDS.

SCA CONDITIONS ARE LIKELY MONDAY MORNING AS A STRONG LOW PRESSURE
SYSTEM PUSHES OFFSHORE AND CAA OCCURS BEHIND A COLD FRONT. AS THE
PRESSURE GRADIENT REMAINS PINCHED GALES ARE NOT OUT OF THE
QUESTION...THEREFORE A GALE WATCH WILL CONTINUE UNTIL 15Z MONDAY.
SUSTAINED 20 TO 25 KNOT WINDS WITH A FEW GUSTS OVER 30 ARE
ANTICIPATED UNTIL LATE MONDAY MORNING. SEAS OF 4 TO 6 FEET IN THE
NEARSHORE SC AND GA WATERS AND 6 TO 8 FEET IN THE OUTER GA WATERS
ARE LIKELY IN THE MORNING BEFORE CONDITIONS IMPROVE.

CONDITIONS ARE LIKELY TO IMPROVE MONDAY EVENING AS THE LOW PRESSURE
SYSTEM CONTINUES TO SHIFT EAST OVER THE GULF STREAM AND THE PRESSURE
GRADIENT ALONG THE SC AND GA COASTS WEAKENS. THE EFFECTS OF CAA WILL
LESSON AS WELL AS WINDS BEGIN TO CLOCK AROUND TUESDAY MORNING AND A
WEAK ONSHORE FLOW DEVELOPS. SEAS ARE FORECASTED AROUND 2 FEET OVER A
MAJORITY OF THE WATERS. CONDITIONS ARE ANTICIPATED TO REMAIN BELOW
SCA CRITERIA THROUGH MID WEEK AS SOUTHEAST WINDS OF 5 TO 10 KNOTS
OCCUR FOR THE FOLLOWING FEW DAYS. SEAS WILL GRADUALLY BUILD TO 3 TO
5 FEET THROUGH LATE WEEK AS A SOUTH SOUTHEAST SWELL DEVELOPS AND THE
APPROACH OF ANOTHER LOW PRESSURE SYSTEM OCCURS.

.FIRE WEATHER...CONDITIONS COULD APPROACH RED FLAG ON MONDAY
BEHIND A COLD FRONT BUT FUELS EXPECTED TO BE FAIRLY MOIST AFTER
RECENT RAINS.
