An unstable and slightly sheared environment ahead of a frontal boundary resulted in thunderstorm development in the Central Savannah River Area around mid afternoon. The multicell convection then moved southeast along various boundaries and the sea breeze into southeast Georgia and the adjacent Atlantic Coastal Waters.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
309 PM EDT SUN JUL 11 2010
...SEVERE THUNDERSTORM WATCH UNTIL 9 PM EDT...
.SYNOPSIS...
A WEAK COLD FRONT WILL DISSIPATE NORTH OF THE AREA THROUGH MONDAY.
THE AREA WILL BE BETWEEN EXPANDING ATLANTIC HIGH PRESSURE AND AN
INLAND SURFACE TROUGH THROUGH THE UPCOMING WEEKEND.
&&
.NEAR TERM /THROUGH TONIGHT/...
THUNDERSTORMS ARE SLOWLY ORGANIZING AHEAD OF A WEAK AREA OF LOW
PRESSURE POSITIONED JUST SOUTH OF AUGUSTA. 11/18Z SURFACE ANALYSIS
PLACED THE COLD FRONT SOUTH OF ATLANTA AND EXTENDING NORTHEAST TO
JUST NORTH OF COLUMBIA AND BENNETTSVILLE THEN ARCHING SHARPLY
SOUTHEAST TOWARDS NORTH MYRLE BEACH. THE FRONT WILL MOVE LITTLE
TONIGHT...POSSIBLY MEANDERING ANOTHER 20-40 MILES TO THE SOUTH.
SURFACE-BASED INSTABILITY CONTINUES TO GROW SOUTH OF THE FRONT
WITH TEMPERATURES INCREASING INTO THE LOWER-MID 90S WITH DEWPOINTS
IN THE MID 70S. TEMPERATURES HAVE BEEN HELD DOWN IN THE CHARLESTON
TRI-COUNTY AREA DUE TO PERSISTENT THICKER CLOUD COVER AND HAZE...
BUT WITH DECENT BREAKS IN THE CLOUDS RECENTLY NOTED...TEMPERATURES
WILL MAKE A RUN FOR THE LOWER 90S PRIOR TO SUNSET.
THERE HAVE BEEN NO MAJOR SHIFTS IN OUR CONVECTIVE ASSESSMENT FROM
THIS MORNING. HIGH RESOLUTION MODEL DATA INCLUDING THE H3R AND
4KM-WRF SUPPORT CONTINUED CONVECTIVE DEVELOPMENT AND EVENTUAL
ORGANIZATION AS THE AFTERNOON AND EVENING PROGRESSES WITH MUCH OF
THE ACTIVITY CONCENTRATING ALONG OR JUST SOUTH OF THE SAVANNAH
RIVER. ADDITIONAL ACTIVITY WILL LIKELY DEVELOP ELSEWHERE AS THE
SEA BREEZE MOVES INLAND AND INTERACTS WITH OTHER MESOSCALE
BOUNDARIES LURKING ABOUT. MODIFIED SOUNDINGS SUPPORT IMPRESSIVE
THERMODYNAMIC PARAMETERS WITH SBCAPES IN EXCESS OF 3000 K/JG...LI
OF -8C AND SI OF -2C. WITH SLIGHTLY DRIER AIR IN PLACE ALOFT...
DCAPES HAVE INCREASED TO NEAR 1500 J/KG COMPARED TO 800 J/KG
YESTERDAY WITH A HIGHER WET-MICROBURST INDEX AND A GREATER DELTA
EPT NUMBER. 12Z GUIDANCE CAME IN WITH GREATER SHEAR PARAMETERS
COMPARED TO THE PAST SEVERAL DAYS WITH 0-6KM BULK SHEAR AROUND
30-35 KT. THIS WILL SUPPORT A GREATER POTENTIAL FOR ORGANIZED
STRONG-SEVERE MULTICELLULAR CLUSTERS WITH AN ENHANCED POTENTIAL
FOR DAMAGING WINDS...ESPECIALLY NEAR MESOSCALE BOUNDARY
COLLISIONS. CELLS MAY ALSO TAKE ON BRIEF SUPERCELLULAR
CHARACTERISTICS AT TIMES. A SEVERE TSTM WATCH HAS BEEN ISSUED FOR
THE ENTIRE FORECAST AREA UNTIL 9 PM. WILL CONTINUE TO HIGHLIGHT
30-50 PERCENT POPS FOR TONIGHT WITH THE HIGHEST GRIDDED POPS
CLUSTERED ALONG THE SAVANNAH RIVER. WILL LIKELY HAVE TO MAKE
FURTHER REFINEMENTS AS THE AFTERNOON AND EVENING PROGRESSES AND
SHORT TERM TRENDS BECOME MORE APPARENT.
TEMPERATURES HAVE HAD A HARD TIME RECOVERING OVER THE CHARLESTON
TRI-COUNTY AREA. ALTHOUGH TEMPERATURES SHOULD PEAK IN THE LOWER
90S...ITS BECOMING MORE APPARENT THAT HEAT INDICES WILL LIKELY NOT
REACH ADVISORY THRESHOLDS OF 105 FOR 2 OR MORE HOURS. WILL CLEAR
DORCHESTER/COLLETON/CHARLESTON AS WELL AS TIDAL AND INLAND
BERKELEY COUNTIES FROM THE ADVISORY. WILL ALSO REMOVE PARTS OF THE
FAR INTERIOR PARTS OF THE FORECAST AREA WHERE THUNDERSTORMS HAVE
OCCURRED. OTHERWISE...THE HEAT ADVISORY LOOKS ON TRACK FOR THE
REMAINDER OF THE FORECAST AREA WITH 105-108 COMMON IN A NUMBER OF
AREAS. STILL LOOKING FOR A MESOSCALE DEWPOINT SURGE TO OCCUR ALONG
THE NORTH GEORGIA AND POSSIBLY THE FAR SOUTHERN SOUTH CAROLINA
COAST WHICH WILL HELP PUSH VALUES NEAR 110 FOR A FEW MORE HOURS.
CONVECTION WILL GRADUALLY WANE OVERNIGHT...BUT WITH A WARM AND
MUGGY NIGHT EXPECTED THE RISK FOR AT LEAST ISOLATED SHOWER/TSTM
ACTIVITY WILL PERSIST THROUGH EARLY MONDAY MORNING. AFTER FAIRLY
HIGH EVENING POPS...WILL SHOW A LEAST 20 PERCENT POPS LINGERING
THROUGH 6 AM MONDAY. LOWS WILL RANGE FROM THE MID-UPPER 70S WITH
LOWER 80S AT THE BEACHES.
&&
.SHORT TERM /MONDAY THROUGH WEDNESDAY NIGHT/...
UPPER LEVEL HEIGHTS WILL BE RISING THROUGH THE PERIOD IN THE WAKE OF
THE DEPARTING WESTERN ATLANTIC TROF AND IN ADVANCE OF AN UPPER LEVEL
TROF APPROACHING FROM THE WEST BY WEDNESDAY. PRECIPITABLE WATER
VALUES BETWEEN 2 AND 2.5 INCHES THROUGH THIS PERIOD WILL LEAD TO A
FAIRLY ACTIVE PERIOD WITH SCATTERED MAINLY AFTERNOON AND EVENING
THUNDERSTORMS. WITH SOME SUNSHINE...EXPECT THE COMBINATION OF
AFTERNOON TEMPERATURES IN THE LOWER TO MID 90S WITH DEWPOINTS MAINLY
IN THE MID 70S TO RESULT IN LIFTED INDICES OF -4 TO -8 AND SURFACE
BASED CAPES IN EXCESS OF 3000 J/KG. THIS WILL LIKELY RESULT IN
SCATTERED THUNDERSTORMS FORMING ALONG THE SEA BREEZE...INLAND ALONG
A SURFACE TROF AND THEN ALONG OUTFLOW BOUNDARIES. FOR NOW HAVE KEPT
CHANCE POPS FOR EACH AFTERNOON AND EVENING AND LATER SHIFTS MAY NEED
TO RAISE POPS INTO THE LIKELY CATEGORY...ESPECIALLY ON TUESDAY AND
WEDNESDAY WHICH LOOK TO HAVE THE BEST CHANCE OF HAVING BETTER
COVERAGE. THUNDERSTORMS DURING THIS PERIOD WILL BE CAPABLE OF
PRODUCING VERY HEAVY RAINFALL AND FREQUENT LIGHTNING.
THE COMBINATION OF HIGH TEMPERATURES MAINLY IN THE LOWER TO MID 90S
AND DEWPOINT TEMPERATURES MAINLY IN THE MID 70S MAY RESULT IN HEAT
INDICES AT OR ABOVE 105 DEGREES FOR A FEW HOURS EACH AFTERNOON AND
PERHAPS INTO THE EVENING HOURS.
&&
.LONG TERM /THURSDAY THROUGH SATURDAY/...
ATLANTIC HIGH PRESSURE LOOKS TO REMAIN IN CONTROL MOST OF THE
PERIOD. A TROUGH OF LOW PRESSURE ACROSS THE MIDLANDS ALONG WITH THE
SEA BREEZE WILL MAINTAIN A CHANCE OF SHOWERS AND STORMS...MAINLY
EACH AFTERNOON AND EVENING. TEMPERATURES WILL BE SLIGHTLY ABOVE
NORMAL THROUGH THE PERIOD.
&&
.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
THE MAIN NEAR TERM CONCERN IS WHETHER TSTMS WILL IMPACT THE
TERMINALS THROUGH THIS EVENING. RADAR IS ALREADY SHOWING TSTMS
FIRING ALONG THE SAVANNAH RIVER WHERE THE BEST JUXTAPOSITION OF
INSTABILITY AND MESOSCALE BOUNDARIES ARE OCCURRING. A NW STEERING
FLOW SUGGESTS SOME OF THIS ACTIVITY WILL IMPACT KSAV LATER THIS
AFTERNOON AS ADDITIONAL TSTMS DEVELOP. WILL INCLUDE A TEMPO GROUP
FOR 3SM TSRA BR ALONG WITH CONVECTIVE WIND GUSTS FROM 21-23Z. WILL
ISSUE AMENDMENTS AS NEEDED IN CASE CHANGES IN TIMING ARE
NECESSARY. TSTMS LOOK TO REMAIN W OF KCHS SO WILL KEEP THAT TAF
FREE OF TSTMS. OTHERWISE VFR CONDITIONS WILL PREVAIL. THERE IS A
POSSIBILITY FOR SOME LIGHT MVFR VSBYS FROM GROUND FOG TONIGHT.
EXTENDED AVIATION OUTLOOK...BRIEF PERIODS OF MVFR GROUND FOG
POSSIBLE AROUND DAYBREAK EACH MORNING. SCATTERED SHRA/TSRA COULD
RESULT IN BRIEF FLIGHT CATEGORY RESTRICTIONS MAINLY EACH
AFTERNOON/EVENING.
&&
.MARINE...
THERE ARE NO MAJOR CONCERNS OVER THE MARINE AREA TONIGHT. A
GENERAL SOUTHERLY WIND FIELD IS EXPECTED...BUT WINDS MAY BECOME
CHAOTIC LATER THIS EVENING AS THUNDERSTORMS APPROACH.
MONDAY THROUGH FRIDAY...FAIRLY TRANQUIL CONDITIONS EXPECTED
THROUGH THE PERIOD AS ATLANTIC HIGH PRESSURE RIDGES TOWARDS THE
AREA. NOCTURNAL SURGES COULD RESULT IN WINDS OF UP TO 20 KNOTS IF
NOT DISTURBED BY EVENING CONVECTION. OTHERWISE...EXPECT WINDS OF
15 KNOTS OR LESS THROUGH THE PERIOD. SEAS SHOULD MAINLY BE IN THE
1 TO 3 FOOT RANGE...WITH SOME 4 FOOT SEAS POSSIBLE MORE THAN 40
MILES OFF THE GEORGIA COAST.
&&
.TIDES/COASTAL FLOODING...
TIDAL DEPARTURES WERE RUNNING 0.2-0.3 FT ABOVE PREDICTED LEVELS
WITH THIS AFTERNOON/S LOW TIDE CYCLE. A SIMILAR DEPARTURE IS
EXPECTED FOR THIS EVENING/S HIGH TIDE CYCLE...WHICH WILL PUSH
TIDES NEAR 7.0 FT MLLW IN THE CHARLESTON HARBOR. WILL ISSUE A
COASTAL FLOOD ADVISORY FOR THE SOUTH CAROLINA COASTAL ZONES FROM 6
PM UNTIL 10 PM THIS EVENING. THE RISK FOR FLOODING MAY ALSO
INCREASE FOR COASTAL LOCATIONS AS THUNDERSTORMS WITH HEAVY RAIN
COULD POTENTIALLY AFFECT THOSE AREAS LATER THIS EVENING. ELEVATED
TIDES WILL PERSIST FOR ANOTHER TWO DAYS AND ADDITIONAL COASTAL
FLOOD ADVISORIES MAY BE NEEDED.
