AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
1048 AM EDT SAT JUL 28 2007

.SYNOPSIS...
MEAN MID AND UPPER TROUGH POSITION TO REMAIN ALONG THE ERN STATES
AND INTO OUR REGION THROUGHOUT MUCH OF THE FCST PERIOD...ALTHOUGH
ATLC RIDGING WILL TRY TO BUILD BACK TOWARD THE AREA LATE NEXT WEEK.
MEANWHILE...PIEDMONT TROUGH TO FORM TODAY AND WILL SHIFT INTO THE
AREA TONIGHT AND SUNDAY...THEN LINGER NEARBY MONDAY. A SURFACE
FRONTAL BOUNDARY COULD APPROACH BY MID WEEK...THEN LINGER NEARBY
THROUGH NEXT FRIDAY. OCNL SHORT WAVES WILL MOVE THROUGH THE TROUGH
ALOFT...ONE SUCH TODAY AND ANOTHER ON MON. THIS ALONG WITH VARIOUS
BOUNDARIES SUCH AS THE SEA BREEZE WILL AID IN POSSIBLE STRONG OR
ISOLATED SEVERE TSTMS DURING THIS TIME.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
ASCENT AHEAD OF APPROACHING SHORTWAVE...OUTFLOW BOUNDARIES
CREATED BY EARLIER CONVECTION AND MOST UNSTABLE CAPES 2000-3000
J/KG WERE SUPPORTING EARLY INITIATION OF THUNDERSTORMS THIS
MORNING...SCATTERED ACROSS THE FORECAST AREA BUT WIDESPREAD
UPSTREAM...CLOSER TO THE APPROACHING SHORTWAVE. PER CURRENT
TRENDS...BUMPED POPS TO CATEGORICAL N/W AND LIKELY S/E FOR
TODAY...WITH HIGHEST POPS THIS AFTERNOON...AND RAISED CLOUD COVER
AND LOWERED TEMPERATURES ACCORDINGLY.

THE 12Z KCHS SOUNDING YIELDED WORST CASE SURFACE BASED CAPES
AROUND 3500 J/KG...ALTHOUGH THESE VALUES MAY ONLY BE REALIZED
ACROSS FAR S COUNTIES...AS CLOUD COVER AND AN EARLIER ONSET OF
PRECIPITATION SHOULD HOLD DOWN TEMPS AND ASSOCIATED INSTABILITY
ELSEWHERE. THE COMBINATION OF SYNOPTIC FORCING...INSTABILITY AND A
BOUNDARY RICH ENVIRONMENT WILL SUPPORT SEVERE WEATHER ACROSS THE
REGION AT ANY TIME INTO EARLY AFTERNOON. THEN...WIDESPREAD
PRECIPITATION AND ASSOCIATED STABILIZATION MAY LIMIT SEVERE
POTENTIAL ACROSS N/W COUNTIES FOR THE BALANCE OF THE AFTERNOON.
ACROSS S COUNTIES...PRECIPITATION COVERAGE MAY NOT BE
WIDESPREAD...ALLOWING GREATER HEATING/DESTABILIZATION...AND
STRONG/SEVERE THUNDERSTORMS MAY CONTINUE TO FIRE ALONG THE
SOUTHERN PERIPHERY OF THE NORTHERN PRECIPITATION SHIELD INTO THE
EVENING. OTHERWISE...MOST CONVECTION SHOULD REMAIN MULTICELLULAR
IN NATURE...HOWEVER...BOUNDARY INTERACTIONS WILL SUPPORT SHORT
LIVED SUPERCELL STORMS...WITH AN ENHANCED RISK OF DAMAGING
WINDS...LARGE HAIL AND EVEN ISOLATED TORNADOES.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/...
SHORT WAVE MOVES INTO THE ATLC EARLY TONIGHT BUT DOES NOT CLEAR THE
COASTAL WATERS ENTIRELY UNTIL 12Z SUNDAY. IN WAKE OF THIS SHORT WAVE
NVA WILL DEVELOP ON SUNDAY...WITH PRESENT INDICATIONS ARE THAT NO
SIGNIFICANT SHORT WAVES WILL AFFECT THE FCST AREA.

WILL NEED TO KEEP SCATTERED OR LIKELY POPS GOING EARLY TONIGHT OVER
LAND AREAS...AND INTO THE OVERNIGHT HOURS OVER THE ATLC WITH
AFOREMENTIONED SHORT WAVE. ISOLATED STRONG OR SEVERE STORMS ARE
CERTAINLY POSSIBLE EVEN OVER THE ATLC. LOWS TONIGHT WILL BE IN THE
LOWER TO MIDDLE 70S.

SURFACE TROUGH MOVES INTO THE AREA TONIGHT AND SUNDAY...AND THAT
ALONG WITH THE SEA BREEZE WILL BE THE FOCUS FOR CONVECTION ON
SUNDAY. WHILE THERE ARE LITTLE IF ANY DYNAMICS ALOFT...CAPES ARE
SLIGHTLY HIGHER THAN TODAY AND THERE IS EVEN A LITTLE MORE MOISTURE.
WILL PLAN ON AT LEAST 50 PERCENT POPS ON SUNDAY...PERHAPS EVEN
HIGHER IF SURFACE WAVES DEVELOP ALONG THE TROUGH AND MOVE INTO THE
CWFA. A FEW STRONG OR SEVERE TSTMS ARE POSSIBLE WITH PROXIMITY TO
SURFACE TROUGH...ALTHOUGH WARMER MID LEVEL TEMPS AND MID LEVEL LAPSE
RATES THAN TODAY WILL CERTAINLY KEEP DOWN THE OVERALL COVERAGE OF THE
SEVERE POTENTIAL. WILL STILL MENTION IN THE HWO.

&&

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
UPPER TROUGHING/ASSOCIATED SHORTWAVES PUSHING NW TO SE THROUGH THE
PARENT TROUGH...SEA BREEZE CONVERGENCE AND AMPLE LOW LEVEL
INSTABILITY WILL SUPPORT AN ABOVE AVERAGE CHANCE FOR THUNDERSTORMS
DURING MONDAY.,,WITH CONVECTION COVERAGE/INTENSITY PEAKING DURING
THE AFTERNOON/EVENING HOURS. WITHIN AN UNSTABLE/WEAKLY SHEARED
ENVIRONMENT...ISOLATED THUNDERSTORMS MAY PRODUCE DAMAGING
MICROBURSTS AND HAIL MONDAY AFTERNOON/EVENING. SLIGHTLY STRONGER
LOW/MID LEVEL WIND FIELDS MAY SUPPORT A GREATER POTENTIAL FOR
MULTICELL THUNDERSTORM ORGANIZATION MONDAY.

THE UPPER LEVEL TROUGH WILL PERSIST THROUGH THE PERIOD. THIS FEATURE
WILL PUSH A BROAD SURFACE BOUNDARY INTO THE VICINITY BY TUESDAY...
THEN...THE SURFACE BOUNDARY IS PROGGED TO STALL THEN WEAKEN OVER OR
CLOSE TO THE REGION...ON THE PERIPHERY OF THE RIDGE HOLDING GROUND
SE OF THE AREA...THROUGH THE REST OF THE WEEK. THIS REGIME SHOULD
COMBINE WITH DIURNAL SEA BREEZE CONVERGENCE TO SUPPORT AT LEAST
SCATTERED CONVECTION...ESPECIALLY DURING THE AFTERNOON AND EVENING
HOURS EACH DAY.

&&

.AVIATION /14Z SATURDAY THROUGH WEDNESDAY/...
MID AND HIGH CLOUDINESS WILL LOWER AND THICKEN ACROSS THE
TERMINALS BY LATE MORNING/EARLY AFTN. SHORT WAVE WILL MOVE THROUGH
THIS AFTN AND INTO THE ATLC BY 03-06Z TONIGHT. THIS ALONG WITH
VARIOUS SURFACE BOUNDARIES /APPROACHING TROUGH...OUTFLOWS AND THE SEA
BREEZE/ WILL RESULT IN SHRA/TSRA IMPACTING BOTH KCHS AND KSAV THIS
AFTN INTO THIS EVE.

FOR NOW WILL NOT GO ANY LOWER THAN MVFR CONDITIONS FROM 18/19Z TO
22/23Z...BUT POTENTIAL DOES EXIST FOR A PERIOD OF IFR WX.

WILL CONTINUE TO CARRY -SHRA AT BOTH SITES UNTIL SHORT WAVE CLEARS
THE COAST OVERNIGHT.

LIGHT/VRBL WINDS THIS MORNING WILL BECOME W AND SW AT LESS THAN 10
KT THIS AFTN...WITH SEA BREEZE HAVING A HARD TIME REACHING THE
TERMINALS DUE TO WLY SYNOPTIC FLOW. THERE COULD BE STRONGER WIND
GUSTS AT EITHER TERMINAL WITH ANY TSRA THIS AFTN/EVE...BUT FOR NOW
HAVE CAPPED WINDS AT 25 KT.

MOST LIKELY TOO MUCH CLOUD COVER FOR ANY FOG TONIGHT...BUT GIVEN
GOOD RAINS TODAY WILL NEED TO WATCH FOR ANY MVFR VSBYS SHOULD
CLOUD COVER BREAK FOR A TIME IN WAKE OF SHORT WAVE.

EXTENDED AVIATION OUTLOOK...OUTSIDE POSSIBLE MVFR OR
LOWER CONDITIONS WITHIN SCATTERED MAINLY AFTERNOON AND EVENING
THUNDERSTORMS...AND BRIEFLY ASSOCIATED WITH FOG AROUND
DAYBREAK...VFR CONDITIONS WILL PREVAIL THROUGH THE PERIOD.

&&

.MARINE...
WEAK PRESSURE GRADIENT WILL REMAIN OVER THE COASTAL WATERS
TODAY...ALLOWING THE SEABREEZE TO DOMINATE THE SURFACE WINDS
THROUGH THE AFTERNOON. ADJUSTED WIND DIRECTION FORECASTS TO
ACCOUNT FOR ONGOING TRENDS. OTHERWISE...CONDITIONS WILL REMAIN
FAVORABLE FOR STRONG THUNDERSTORMS WITH GUSTY WINDS...HAIL AND
PERHAPS EVEN WATERSPOUTS. OUTSIDE THUNDERSTORMS...WINDS/SEAS WILL
REMAIN WELL BELOW HEADLINE CRITERIA.

A WEAK SURFACE LOW WILL DROP SOUTHEAST TOWARD THE FORECAST AREA
TONIGHT THROUGH THE WEEKEND. HAVE PREFERRED THE SLOWER GFS
SOLUTION...WHICH KEEPS THE ASSOCIATED SURFACE BOUNDARY TO THE
NORTH UNTIL MONDAY NIGHT.

THE PRESSURE GRADIENT WILL INCREASINGLY TIGHTEN OVER THE COASTAL
WATERS TONIGHT THROUGH MONDAY NIGHT...REFLECTED IN MODEL BOUNDARY
LAYER WIND FIELDS. TYPICAL DIURNAL SEABREEZE PATTERN WILL STILL
CONTINUE DURING THIS PERIOD...HOWEVER EXPECT NOCTURNAL SURGES AND
AFTERNOON SEABREEZE PUSH TO BE STRONGER SUNDAY AND MONDAY AS A
RESULT. AT THIS POINT HAVE KEPT WINDS AND SEAS BELOW ANY ADVISORY
CRITERIA...BUT CANNOT RULE OUT A POSSIBLE SCEC IN THE OFFSHORE
WATERS AND CHARLESTON HARBOR SUNDAY OR MONDAY. OTHERWISE...WINDS
AND SEAS ARE EXPECTED TO REMAIN BELOW HEADLINE CRITERIA THROUGH
MIDWEEK.

RIP CURRENTS...WHILE THE RIP CURRENT FCST FOR TODAY IS LOW...WE
DID HAVE REPORTS FROM KIAWAH OF 2 RIP CURRENTS YESTERDAY...AND A
REPORT OF A RIP CURRENT AT FOLLY BEACH THIS MORNING...WHICH APPEARS
TO HAVE OCCURRED DURING MARGINAL CONDITIONS FEATURING SWELLS
AROUND 2 FT EVERY 9-10 SECONDS.

TIDES...ASTRONOMICAL HIGH TIDES WILL NEED TO BE WATCHED THIS EVE
SHOULD HEAVY RAINS BE ONGOING DURING THE HIGH TIDE AROUND 8 AND 9
PM. THIS COULD RESULT IN SHALLOW COASTAL FLOODING CONCERNS GIVEN
RECENT LEVELS A LITTLE HIGHER THAN PREDICTED.
