AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
336 PM EDT WED AUG 22 2007

.SYNOPSIS...
HIGH PRESSURE WILL REMAIN IN PLACE THROUGH THE WEEKEND. A COLD
FRONT WILL APPROACH THE AREA EARLY NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
CURRENTLY AT THE SURFACE...HIGH PRESSURE IS LARGELY IN CONTROL OF
THE WEATHER ACROSS THE SE CONUS. THE RIDGE IS FAIRLY WEAK
HOWEVER...WITH A WEAK SFC TROUGH IN THE LEE OF THE APPALACHIANS...AS
WELL AS A WEAK FRONTAL BOUNDARY STRETCHING FROM SOUTHEASTERN NC INTO
SOUTHWESTERN VA. VIS SAT IMAGERY INDICATES PARTLY CLOUDY SKIES IN
PLACE ACROSS THE FORECAST AREA...WITH RADAR IMAGERY SHOWING
SCATTERED SHWRS/TSTMS DEVELOPING ACROSS WESTERN ZONES. MAIN NEAR
TERM CONCERN FOR TONIGHT REVOLVES AROUND POPS.

TONIGHT...
A SERIES OF WEAK SHORTWAVES WILL CONTINUE TO ROTATE AROUND THE
PERIPHERY OF UPPER RIDGE AND THROUGH THE FORECAST AREA. EXPECT THAT
MOST CONVECTION WILL BE DIURNALLY DRIVEN AND DISSIPATE THIS
EVENING...BUT GIVEN SHORTWAVE ENERGY SPILLING INTO THE
REGION...ALONG WITH APPROACH OF DISSIPATING FRONTAL BOUNDARY
CURRENTLY IN SOUTHEASTERN NC...WILL MAINTAIN SLGT CHC POPS ALL ZONES
THROUGH THE NIGHT. EXPECT ANOTHER VERY MILD NIGHT...WITH LOWS IN THE
MID TO UPPER 70S.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/...
THE WEAK FRONTAL BOUNDARY WILL PUSH INTO THE REGION AND DISSIPATE
OVER THE AREA ON THURSDAY...WITH ATLANTIC HIGH PRESSURE THEN
BEGINNING TO RE-ESTABLISH ITSELF THURSDAY NIGHT. MEANWHILE...H5
SHORTWAVE ENERGY WILL CONTINUE TO DROP SOUTHWARD THROUGH THE REGION
ON THE PERIPHERY OF UPPER RIDGE. HAVE INCREASED POPS INTO THE CHC
RANGE THURSDAY AFTERNOON...AS COMBINATION OF STRONG SURFACE
HEATING...DISSIPATING FRONTAL BOUNDARY DRAPED THROUGH THE
REGION...ALONG WITH AFTERNOON SEA BREEZE DEVELOPMENT...SHOULD LEAD
TO AN INCREASE IN SHWR/TSTM COVERAGE ACROSS THE AREA. ADJUSTING
MODEL SOUNDINGS YIELDS CAPE VALUES OF 2800 TO 3200 J/KG AND LI/S
AROUND -6. CAN/T RULE OUT A FEW SEVERE THUNDERSTORMS...WITH WET
MICROBURSTS THE MOST LIKELY THREAT...PRODUCING DAMAGING WIND GUSTS.
SHWR/TSTM ACTIVITY SHOULD DECREASE IN INTENSITY AND AREAL COVERAGE
QUICKLY IN THE EVENING...BUT WILL KEEP SLGT CHC POPS GOING
OVERNIGHT...WITH SHORTWAVE ENERGY CONTINUING TO ROTATE THROUGH THE
AREA. AS FOR TEMPERATURES...EXPECT HIGHS IN THE LOW TO MID 90S
THU...WITH OVERNIGHT LOWS IN THE LOW TO MID 70S.

&&

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
WEDNESDAY AFTERNOON /AUG 24TH/...A BROAD TROPICAL WAVE...SPREAD
BETWEEN 75W AND 65W...WITH A CREST ROUGHLY TO 32N...CONTINUED TO
PRESS WEST. FRIDAY THROUGH SUNDAY...12Z GFS/NAM 500 MB PROGS OF
HEIGHT/VORTICITY SUGGEST THAT THE SW-NE DEFORMATION AXIS WITH
EMBEDDED VORTICITY MAXIMA...CENTERED OVER COASTAL COUNTIES OF THE
FORECAST AREA/ON THE EASTERN RIM OF THE ANTICYCLONIC GYRE CENTERED
WEST OF THE REGION...WILL PHASE WITH THE NORTHERN CREST OF THIS
TROPICAL WAVE...RESULTING IN AN INVERTED UPPER TROUGH OVER THE
AREA. SUPPORTING FACTORS FOR ISOLATED TO SCATTERED CONVECTION
TYPICAL OF LATE AUGUST WILL ALREADY BE PRESENT...INCLUDING AMPLE
INSTABILITY...SEA BREEZE CONVERGENCE AND MESOSCALE BOUNDARY
INTERACTION...AND WEAK ASCENT SUPPORTED BY THE UPPER TROUGH MAY
ENHANCE CONVECTION COVERAGE/INTENSITY...ESPECIALLY DURING THE
AFTERNOON/EVENING. ON THE OTHER HAND...WHILE THE CORE OF THE UPPER
RIDGE WILL REMAIN WEST OF THE REGION...THE EASTWARD EXTENT OF THIS
RIDGE REMAINED EVIDENT WITHIN MODEL SOUNDINGS...WHICH EXHIBITED A
SUBSIDENCE INVERSION SIGNATURE THROUGH THE PERIOD...SUGGESTING
THAT CAPPING/DRY AIR ALOFT MIGHT LIMIT COVERAGE OF CONVECTION. AS
OF WEDNESDAY AFTERNOON...THERE REMAINED UNCERTAINTY ABOUT THE
BALANCE BETWEEN THESE ENHANCING/SUPPRESSING FACTORS...AS A
COMPROMISE EDGED POPS UPWARD INTO CHANCE CATEGORY EACH
AFTERNOON/EVENING...AS SUGGESTED BY 12Z GFS MOS GUIDANCE.
HOWEVER...THE SCENARIO SUGGESTS THAT THIS GENERAL FORECAST MAY
REQUIRE NUMEROUS ADJUSTMENTS AS SHORT/NEAR TERM CONVECTIVE FACTORS
BECOME APPARENT.

MONDAY THROUGH WEDNESDAY...LATEST MEDIUM RANGE GUIDANCE HAS TRENDED
BACK TOWARD A STRONGER/MORE PERSISTENT RIDGE OVER THE SE
US...SLOWING THE PROGRESS OF AN APPROACHING COLD FRONT...EVENTUALLY
CAUSING THE FRONT TO STALL/DISSIPATE OVER OR NORTH OF THE REGION.
WILL CONTINUE CHANCE POPS DAY/SLIGHT CHANCE POPS NIGHT THROUGH THE
PERIOD...BUT IN THE END THE BOUNDARY MAY WASH OUT WELL NORTH OF THE
REGION AND MAY NOT BECOME A FACTOR IN THIS FORECAST PERIOD...WITH
CONVECTION INSTEAD SUPPORTED BY INSTABILITY...MESOSCALE
BOUNDARIES/BOUNDARY INTERACTIONS AND WEAKNESS WITHIN THE MID/UPPER
LEVEL RIDGE.

&&

.AVIATION /20Z WEDNESDAY THROUGH MONDAY/...
VFR CONDITIONS SHOULD PREVAIL THROUGH THE ENTIRE TAF PERIOD. CU
EXPECTED TO DEVELOP OVER BOTH TERMINALS TODAY AS CONVECTIVE TEMPS
ARE REACHED AND A SEA BREEZE PUSHES INLAND IN THE AFTERNOON.
MENTIONED CB DURING SEA BREEZE ARRIVAL. LOW CONFIDENCE REMAINS IN
THE TIMING AND DEVELOPMENT OF THUNDERSTORMS IF THEY OCCUR TODAY
OVER BOTH TERMINALS...THUS HAVE KEPT OUT OF TAFS AT THIS TIME.
WINDS WILL BECOME LIGHT AT BOTH TERMINALS TONIGHT. DRY AND WARM
SOIL TEMPS IN THE MID 80S SHOULD CONTINUE MINIMIZING THE CHANCE OF
LOWERING VSBYS TO MVFR LVLS. CONDITIONS MAY CHANGE IF TERMINALS
RECEIVE RAINFALL DURING THE DAY...BUT AT THIS TIME COVERAGE OVER
THE AREA IS EXPECTED TO REMAIN ISOLATED IN NATURE. WINDS WILL
BECOME NORTHEAST TOMORROW MORNING AND INCREASE DURING THE DAY AT
BOTH TERMINALS.

EXTENDED AVIATION OUTLOOK...VFR CONDITIONS WILL PREVAIL THROUGH
MUCH OF THE EXTENDED PERIOD...OUTSIDE OF AN ISOLD AFTN/EVNG SHOWER
OR TSTM.

&&

.MARINE...
ATLANTIC HIGH PRESSURE WILL BEGIN TO LOSE ITS INFLUENCE OVER THE
REGION TONIGHT...AS A WEAK FRONTAL BOUNDARY BEGINS TO APPROACH THE
WATERS FROM THE NORTH. THIS FRONTAL BOUNDARY WILL PUSH INTO THE
WATERS ON THURSDAY AND DISSIPATE. ATLANTIC HIGH PRESSURE WILL THEN
BEGIN TO REBUILD OVER THE WATERS THURSDAY NIGHT. EXPECT FAIRLY
TRANQUIL MARINE CONDITIONS TONIGHT THROUGH THU NIGHT...WITH WINDS
REMAINING BELOW HEADLINE THRESHOLDS. INCREASING SE SWELL MAY
NECESSITATE SCSEC HEADLINES THU NIGHT AND FRI.

FORECAST WILL HOLD WINDS/SEAS BELOW SCSEC CRITERIA FRIDAY NIGHT
THROUGH EARLY NEXT WEEK. HOWEVER...LONG E FETCH ON THE PERIPHERY
OF THE ATLANTIC HIGH WILL CONTINUE TO SUPPORT A PERSISTENT E/SE
SWELL THROUGH EARLY NEXT WEEK...AND THIS SWELL COULD AVERAGE 4-5
FT AT TIMES ON THE COASTAL WATERS...ESPECIALLY ACROSS THE OUTER GA
WATERS. ALSO...THE SYNOPTIC PATTERN WILL CONTINUE TO FAVOR
NOCTURNAL SURGES OF S WINDS ACROSS THE COASTAL WATERS THROUGH THE
PERIOD...PERHAPS SUPPORTING PERIODS OF NEAR SCSEC WINDS. AS A
WEAKENING COLD FRONT APPROACHES FROM THE NORTH EARLY NEXT
WEEK...THE S/SW GRADIENT MAY TIGHTEN...ENHANCING WINDS/SEAS.

RIP CURRENTS...BECAUSE SWELL HEIGHT IMPACTING AREA BEACHES MAY
STRUGGLE TO REACH 3 FEET THURSDAY...AND BECAUSE NO RIP CURRENTS
WERE REPORTED AS OF MID WEDNESDAY AFTERNOON ON AREA BEACHES...
WE WILL FORECAST A LOW RISK OF RIP CURRENTS FOR THURSDAY. FRIDAY AND
SATURDAY...WAVE WATCH GUIDANCE SUGGESTS THAT THE 8-10 SECOND PERIOD
SWELL HEIGHT MAY PUSH BACK INTO THE 3-4 FOOT RANGE...AND THIS MAY
SUPPORT ANOTHER PERIOD OF ELEVATED RISK FOR RIP CURRENTS. SUNDAY AND
BEYOND...WAVE WATCH GUIDANCE SUGGEST THAT SWELL HEIGHT WILL REMAIN
BELOW 3 FEET...HOWEVER...CANNOT RULE OUT HIGHER SWELL REACHING THE
COAST AND ENHANCING THE RIP CURRENT RISK AT ANY TIME INTO MID
WEEK.
