AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
330 PM EDT WED JUN 28 2006

.SHORT TERM /TONIGHT THROUGH THURSDAY NIGHT/...TWO DISTINCT AREAS OF
CONVECTION ARE DEVELOPING IN THE CWA THIS AFTERNOON. THE FIRST LINE
OF THUNDERSTORMS MOVING ENE ORIGINATED FROM THE COLD FRONT STRETCHED
THROUGH CENTRAL NORTH CAROLINA TO CENTRAL GEORGIA. THE SECOND AREA
OF DEVELOPING STORMS IS OCCURRING ALONG THE SEABREEZE FRONT. WITH
PLENTY OF HEAT AND HUMIDITY AIDING INSTABILITY...THE INTERACTION
BETWEEN THE STORMS COMING FROM UPSTREAM AND THE SEABREEZE BOUNDARY
WILL NEED TO BE CLOSELY WATCHED FOR FURTHER DEVELOPMENT OF SEVERE
CONVECTION.

THUNDERSTORM ACTIVITY WILL CONTINUE THROUGH THE AFTERNOON AND INTO
EARLY EVENING. BOTH GFS AND NAM PRECIP FIELDS SUGGEST THAT THERE MAY
BE A SLIGHT CHANCE OF ISOLATED SHOWERS AND THUNDERSTORMS PERSISTING
THROUGH THE NIGHT...SINCE THE AXIS OF THE SURFACE TROUGH MOVES
DIRECTLY OVER THE CWA OVERNIGHT AND ENERGY PROVIDED BY VORT MAXES
WILL STILL BE IN THE AREA. WILL MAINTAIN CHANCE POPS FOR THE
REMAINDER OF THE AFTERNOON AND EVENING...DROPPING TO A SLIGHT CHANCE
BETWEEN MIDNIGHT AND DAWN.

FLOW ALOFT BECOMES WEAKER AND MORE ZONAL AFTER THE AXIS OF THE UPPER
TROUGH BEGINS PUSHING OFFSHORE ON THURSDAY. WEST TO NORTHWEST UPPER
LEVEL FLOW WILL HELP DRY THE ATMOSPHERE A BIT ON
THURSDAY...NOTICEABLE IN THE MODEL SOUNDING PWAT VALUES. WITH THE
DRYER AIR AND LITTLE TO NO FORCING MECHANISMS EXCEPT THE
SEABREEZE...WILL KEEP THE RAINFREE FORECAST FOR THURSDAY. HIGH
TEMPERATURES WILL REACH THE MID 90S ON THURSDAY...WITH LOCALLY
COOLER TEMPERATURES ALONG THE COAST DUE TO SEABREEZE EFFECTS.
&&

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...MEDIUM RANGE GUIDANCE IS IN
GOOD AGREEMENT THROUGH THE EXTENDED PERIOD THIS AFTERNOON...KEEPING
A FAIRLY ZONAL UPPER LEVEL FLOW IN PLACE ACROSS THE AREA. BERMUDA
HIGH PRESSURE WILL BUILD WESTWARD INTO THE FORECAST AREA FRI AND
SAT...AND WILL REMAIN THE DOMINANT WEATHER FEATURE THROUGH THE
MIDDLE OF THE UPCOMING WORK WEEK. WARM MID-LEVEL TEMPERATURES SHOULD
KEEP THE ATMOSPHERE CAPPED FRI THROUGH SUN...PREVENTING ANY SHWR AND
TSTM ACTIVITY FROM DEVELOPING. MAIN RIDGE AXIS IS EXPECTED TO PUSH
SOUTH OF THE FORECAST AREA MON THROUGH WED...LOWERING MID-LEVEL
HEIGHTS ACROSS THE REGION. NOT ANTICIPATING ANY WIDESPREAD
CONVECTION...BUT WITH LOWERING MID-LEVEL HEIGHTS...LEE SIDE
TROUGHING SETTING UP...AND EXPECTED SEA BREEZE DEVELOPMENT...EXPECT
SOME SHWR/TSTM ACTIVITY TO DEVELOP. THEREFORE...WILL MAINTAIN SLGT
CHC POPS MON THROUGH WED. TEMPERATURES THROUGH THE EXTENDED SHOULD
REMAIN NEAR CLIMO.
&&

.AVIATION...A STRONG AND PERSISTENT THUNDERSTORM HAS DEVELOPED ALONG
THE SEABREEZE AT KCHS. THIS STORM IS EXPECTED TO EVENTUALLY MOVE
INLAND WITH THE PROGRESSION OF THE SEABREEZE. CONVECTION WILL ALSO
MOVE INTO THE FORECAST AREA AHEAD OF A FRONT TO THE WEST. THESE
STORMS ARE CURRENTLY FAR ENOUGH AWAY FROM BOTH TERMINALS TO
ENCOURAGE MAINTAINING A GENERIC VCTS DURING THE AFTERNOON AND EARLY
EVENING HOURS...AMENDING IF NECESSARY IF ORGANIZED CONVECTION NEARS
THE TAF SITES. CONVECTIVE ACTIVITY WILL SLOW DOWN AS THE FRONT
BEGINS TO DROP SOUTH INTO THE CWA OVERNIGHT AND INTO THURSDAY
MORNING. WITH FRONTAL APPROACH...SOUTH TO SOUTHWEST FLOW WILL VEER
TO THE WEST BY THURSDAY MORNING.
&&

.MARINE...A WEAK SURFACE TROUGH WILL APPROACH THE MARINE ZONES
TONIGHT AND GRADUALLY WEAKEN...ALLOWING WEST TO SOUTHWEST FLOW TO
LIGHTEN DURING THE SHORT TERM. SEABREEZE SHOULD HAVE NO TROUBLE
PROGRESSING INLAND ON THURSDAY UNDER WEAK SYNOPTIC FLOW. WINDS AND
SEAS WILL REMAIN BELOW ADVISORY CRITERIA TONIGHT THROUGH THURSDAY
NIGHT.

BERMUDA HIGH PRESSURE WILL BUILD WESTWARD OVER THE WATERS FRI AND
SAT...AND WILL REMAIN THE DOMINANT WEATHER FEATURE THROUGH EARLY
NEXT WEEK. WINDS ARE EXPECTED TO REMAIN AOB 15 KT...WITH SEAS AOB 4
FT FRI THROUGH MON.
