AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
434 PM EDT SAT JUN 30 2007
.SYNOPSIS...
A COLD FRONT WILL SLOWLY PUSH SOUTWARD THROUGH THE FORECAST AREA
SUNDAY AND SUNDAY NIGHT. HIGH PRESSURE WILL SLOWLY MOVE INTO
NORTHERN PORTIONS OF THE AREA DURING THE FIRST HALF OF THE WEEK
WHILE THE COLD FRONT STALLS JUST SOUTH OF THE AREA MONDAY THROUGH
WEDNESDAY...THEN DISSIPATES WEDNESDAY NIGHT. ANOTHER COLD FRONT
WILL APPROACH FROM THE WEST TOWARD THE END OF THE WEEK.
&&
.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
SEVERE THUNDERSTORM WATCH 466 REMAINS IN EFFECT FOR THE ENTIRE CWA
THROUGH 00Z.
RADAR DEPICTS CONVECTION FIRING OUT AHEAD OF THE SEA BREEZE BOUNDARY
OVER THE INLAND PORTIONS OF THE CWA AND PUSHING SOUTHWARD. EXPECT
A FEW OF THESE STORMS TO BECOME SEVERE AS CONVERGENCE IS PRESENT
AND MODELS SHOW THE AREA WITH CAPES OVER 3000 J/KG. THESE STORMS
MAY CONTAIN HEAVY RAIN...LARGE HAIL...FREQUENT LIGHTNING AND GUSTY
WINDS. MOST OF THE CONVECTION SHOULD DISSIPATE AFTER SUNSET AS IT
IS MOSTLY DIURNALLY DRIVEN.
WITH PROXIMITY OF FRONTAL BOUNDARY TO THE FORECAST AREA...ALONG
WITH SOME WEAK UPPER LEVEL SHORTWAVES PUSHING TOWARD THE
REGION FROM THE NORTH...WILL CARRY CHC POPS MAINLY IN THE SOUTH
CAROLINA ZONES THROUGH THE OVERNIGHT PERIOD. SLIGHT CHC POPS
REMAINS IN THE SOUTHERN GA ZONES ALSO THROUGH TONIGHT.
AREAS AWAY FROM THE COAST WILL SEE TEMPERATURES FALL INTO THE LOW
70S AWAY FROM THE COAST.
&&
.SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/...
BOTH GFS AND NAM CONTINUES TO PUSH THE COLD FRONT SOUTHWARD
THROUGH THE CWA ON SUNDAY. THIS FEATURE COMBINED WITH THE SEA BREEZE
AND SOME WEAK SHORTWAVES WILL BE JUST ENOUGH TO SPARK ANOTHER
ROUND OF DECENT CONVECTION ACROSS THE AREA. INSTABILITY AND DEEP
LAYER SHEAR PARAMETERS WILL BE SLIGHTLY HIGHER THAN TODAY...AND
WITH FRONTAL BOUNDARY IN THE VICINITY...EXPECT THAT THE RISK FOR
SEVERE WEATHER WILL BE SLIGHTLY HIGHER AS WELL. A FEW OF THE
THUNDERSTORMS THAT DEVELOP HAVE THE POTENTIAL OF BECOMING SEVERE.
EXPECT HEAVY RAIN...SMALL HAIL...FREQUENT LIGHTNING AND GUSTY
WINDS ASSOCIATED WITH THESE STORMS. WITH THE FRONT PUSHING SOUTH
OF THE CWA SUNDAY NIGHT...WILL TAPER OFF THE CHC POPS FROM NORTH
TO SOUTH THROUGH THE OVERNIGHT.
HIGH TEMPERATURES WILL TOP OUT IN THE UPPER 80S TO LOWER 90S
HIGHEST ACROSS THE EASTERN AND SOUTHERN ZONES. LOW TEMPERATURES
WILL BE A COUPLE DEGREES COOLER SUN NIGHT BEHIND THE FRONT.
&&
.LONG TERM /MONDAY THROUGH SATURDAY/...
SFC FNTL BNDRY WILL BE S OF THE CWFA BY MON MRNG THEN EVENTUALLY
STALL OUT NEAR THE FL/GA BORDER MON THROUGH WED BEFORE
DISSIPATING. DRIER AIR AND HIGH PRES WILL FOLLOW THE FNTL
BNDRY...BUT THIS WILL MAINLY SETTLE OVER THE NRN PORTION OF THE
CWFA WHILE THE SRN PORTION WILL REMAIN WITHIN A MODESTLY MOIST
ENVIRONMENT AND STILL BE SUSCEPTIBLE TO SFC CONVERGENCE AND PVM
DUE TO THE PROXIMITY OF THE DISSIPATING FRONT. THUS...HAVE
MAINTAINED SLGT/LOW CHC POPS FOR MAINLY AREAS NEAR THE ALTAMAHA
RIVER THROUGH MIDWEEK WHILE AREAS NEAR AND N OF THE SAVANNAH RIVER
SHALL REMAIN DRY.
WILL NEED TO MAINTAIN SLGT/LOW CHC POPS THROUGH THE LATTER HALF OF
THE WEEK AS ANOTHER FRONTAL SYSTEM APPROACHES FROM THE W. A PAIR OF
PRE-FRONTAL TROFS LOOK TO MOVE ACROSS THE CWFA...ONE THU AND ANOTHER
FRI. THE FRONT ITSELF LOOKS TO MOVE THROUGH THE CWFA ON SAT...
BRINGING THE CHC FOR SHWRS/TSTMS TO THE ENTIRE CWFA BY NEXT WEEKEND.
TEMPS WILL BE BELOW NORMAL FOR THE FIRST HALF OF THE WORKWEEK BEHIND
THE FRONT WITHIN NELY FLOW. HOWEVER...AS THE FRONT S OF THE CWFA
WEAKENS AND ANOTHER FRONTAL BOUNDARY OUT W APPROACHES...SFC FLOW
WILL BECOME MORE SLY AND ALLOW A WARMING TREND TO COMMENCE...
POSSIBLY PUTTING TEMPS A BIT ABOVE NORMAL BEFORE THE CDFNT MOVES
THROUGH.
&&
.AVIATION /20Z SATURDAY THROUGH THURSDAY/...
MAINLY VFR CONDITIONS THROUGH THE TAF PERIOD. THERE IS A POTENTIAL
OF BRIEF MVFR CIGS THIS AFTERNOON ASSOCIATED WITH THE THUNDERSTORMS
THAT DEVELOP IN/NEAR THE TERMINALS. MODELS ARE STILL HINTING AT
BEST RISK OF TSTMS ARE N-NW OF KCHS. HOWEVER...CAN NOT RULE OUT A
MODEST CHC THAT STORMS WILL IMPACT THE CHARLESTON AIRPORT THROUGH
21Z. HAVE TEMPO GROUP FOR BOTH KCHS AND KSAV FOR -SHRA. CONVECTIVE
RISK AT KSAV STILL APPEARS SLIGHTLY LESS...BUT ALSO CAN NOT RULE
OUT A SHOWER/THUNDERSTORM AFFECTING THE AIRPORT.
EXTENDED AVIATION OUTLOOK...PERIODIC MVFR CONDITIONS POSSIBLE ON SUN
AS A FRONT MOVES INTO THE AREA. THEN...VFR CONDITIONS MOST LIKELY
MON THROUGH THU.
&&
.MARINE...
THE COASTAL WATERS WILL BE UNDER A SOUTH SOUTHWESTERLY FLOW
OVERNIGHT SHIFTING TOWARD THE WEST ON SUNDAY. WINDS WILL BE MAINLY
AROUND 10 KNOTS...HIGHER ALONG THE IMMEDIATE COAST WITH THE
DEVELOPMENT OF THE SEA BREEZE. SEAS WILL BE 2 TO 4 FEET THROUGH
SUNDAY NIGHT. DROPPED SCEC HEADLINE FOR THE OFFSHORE GA WATERS AS
RECENT BUOY OBSERVATIONS ARE SLIGHTLY LESS THAN 4 FT.
NELY WINDS AND A BIT OF A PINCHED GRADIENT OVER THE WATERS FOR
THE START OF NEXT WEEK WILL MAKE FOR CONDITIONS RATHER CLOSE TO
SCA LEVELS...PARTICULARLY FOR THE OUTER GA WATERS. IN
ADDITION...THE NEARSHORE WATERS MAY BE SUSCEPTIBLE TO WAVE HEIGHTS
NEAR 6 FT WITH A LONG FAVORABLE FETCH EXPECTED...ESP THE GA
NEARSHORE WATERS. WITH THE FETCH BEING MORE PARALLEL ALONG THE SC
COAST...SEAS SHOULD REMAIN AOB 5 FT FOR THE SC NEARSHORE WATERS.
BY MIDWEEK...AS THE FETCH TURNS TO MORE SLY AND A WEAK PRES PATTERNS
MOVES OVER THE WATERS...WINDS AND SEAS WILL BECOME MORE TRANQUIL AND
REMAIN AS SUCH THROUGH THE END OF THE WEEK.
RIP CURRENTS...WILL MAINTAIN A MODERATE RISK FOR REST OF
TODAY...WITH SEVERAL REPORTS FROM TYBEE WITH 3 RESCUES.
BORDERLINE LOW/MODERATE RISK FOR SUNDAY...BUT LOCAL WORKSHEET DOES
INDICATE LOW RISK...SO FOR CONSISTENCY BETWEEN JAX AND ILM WILL
GO WITH LOW RISK. NEXT SHIFT WILL NEED TO CLOSELY REASSESS THE
SITUATION GIVEN RECENT FULL MOON...RECENT REPORTS AND GOOD BEACH
WEATHER.
ENHANCED RISK RETURNS EARLY TO MIDDLE OF NEXT WEEK WITH AN
INCREASING WAVE FETCH AND A STEADY ONSHORE FLOW.
