AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
507 PM EDT WED AUG 5 2009

.SYNOPSIS...
A LEE SIDE SURFACE TROUGH WILL PERSIST OVER INLAND GEORGIA AND THE
CAROLINAS THROUGH LATE WEEK. AN EXPANSIVE RIDGE OF HIGH PRESSURE
WILL BUILD OVER THE REGION THIS WEEKEND INTO EARLY NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
MOST THUNDERSTORMS WHICH FIRED ALONG A SURFACE TROUGH AND PUSHED
INTO CENTRAL/SOUTHERN COUNTIES/COASTAL AREAS HAD WEAKENED EARLY
WEDNESDAY EVENING...AND THE FOCUS FOR THUNDERSTORMS AND POSSIBLE
SEVERE WEATHER HAD SHIFTED INLAND WHERE OUTFLOW FROM EARLIER
THUNDERSTORMS WILL INTERACT WITH CONVECTION ADVANCING INTO THE
REGION FROM THE WEST. NUMEROUS BOUNDARY INTERACTIONS WILL ENHANCE
UPDRAFTS TO PRODUCE ISOLATED/ OCCASIONAL PULSE SEVERE
EVENTS...CAPABLE OF PRODUCING DAMAGING WIND GUSTS AND HAIL AS
LARGE AS QUARTERS INLAND THIS EVENING. ALSO...A WEAK STEERING
FLOW...A COMPLEX BOUNDARY REGIME AND PWATS AROUND 1.8 INCHES
COULD SUPPORT LOCALIZED FLOODING.

ADJUSTED EVENING POPS ACCORDINGLY...TAPERED FROM CHANCE INLAND TO
SLIGHT CHANCE ALONG THE COAST...TO ALLOW FOR THE POTENTIAL FOR
INLAND THUNDERSTORMS TO PROPAGATE E/SE THIS EVENING. IF INLAND
THUNDERSTORMS BECOME/REMAIN ORGANIZED...MORE WIDESPREAD CONVECTION
COULD DEVELOP AND ADVANCE TO THE COAST LATER THIS EVENING.
HOWEVER...LATEST GUIDANCE CONTINUES TO DEPICT A MARKED DIURNAL
WEAKENING TRENDS AFTER DARK. THUS...MAINTAINED POPS LESS THAN 15
PERCENT OVER LAND STARTING AT 06Z.

WHERE RAIN OCCURS...CLEARING SKIES...LIGHT WINDS AND LOW LEVEL
MOISTURE COULD SUPPORT AREAS OF STRATUS/FOG OVERNIGHT.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/...
THE UPPER TROUGH AND ASSOCIATED SURFACE TROUGH WILL ADVANCE INTO
THE REGION THURSDAY. THESE FEATURES WILL SUPPORT AT LEAST
ISOLATED TO SCATTERED SHOWERS/THUNDERSTORMS BY MIDDAY...AND
NUMEROUS SHOWERS/THUNDERSTORMS COULD DEVELOP DURING THE
AFTERNOON...ESPECIALLY CENTRAL/EAST. DUE TO MODEL DEPICTION OF
SLIGHTLY DRIER 850-500 MB AIR FILTERING INTO THE REGION FROM THE
N/W...LIMITED POPS TO CHANCE FOR NOW.

AS THE UPPER/SURFACE TROUGH PUSH OFFSHORE AND SLIGHTLY DRIER AIR
CONTINUES TO SPREAD INTO THE REGION THURSDAY NIGHT...
SHOWERS/THUNDERSTORMS SHOULD READILY SUCCUMB TO DIURNAL TRENDS
AFTER SUNSET...DISSIPATING QUICKLY OVER LAND.

&&

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
AN UPPER RIDGE WILL SLOWLY STRENGTHEN OVER THE SOUTHEAST UNITED
STATES FRIDAY THROUGH MONDAY. UPPER HEIGHTS WILL REACH THEIR ZENITH
ON MONDAY WHEN THE GFS PROGS A 5970M RIDGE CENTERED DIRECTLY OVER
THE AREA. REMOVED AFTERNOON POPS FROM ALL BUT THE ALTAMAHA REGION
FRI THROUGH SUN BECAUSE THE STRONG MID-LEVEL SUBSIDENCE SHOULD
PREVENT MUCH OF ANY CONVECTION FROM DEVELOPING. HIGH TEMPS IN THE
MID TO UPPER 90S WITH DEWPOINTS REMAINING IN THE LOWER TO MIDDLE 70S
MAY PRODUCE SOME HEAT INDEX CONCERNS OVER THE WEEKEND INTO EARLY
NEXT WEEK. THIS CONTINUES TO BE ADDRESSED IN THE HAZARDOUS OUTLOOK.
THE RIDGE IS EXPECTED TO BEGIN BREAKING DOWN EARLY NEXT WEEK. THIS
SHOULD HELP TO MODERATE TEMPS A BIT AND BRING AN INCREASE TO
AFTERNOON AND EVENING CONVECTION.

&&

.AVIATION /21Z WEDNESDAY THROUGH MONDAY/...
WILL ASSESS POTENTIAL FOR UPSTREAM THUNDERSTORMS TO ADVANCE INTO
TAF SITES LATE THIS EVENING/OVERNIGHT...BUT ODDS FAVOR
THUNDERSTORMS DISSIPATING INLAND AFTER DARK. OUTSIDE ANY
THUNDERSTORMS...VFR CONDITIONS WILL PREVAIL THROUGH THIS EVENING.
WITH LINGERING MOISTURE FROM AFTERNOON RAIN...LIGHT WINDS AND
CLEARING SKIES OVERNIGHT...THERE REMAINS POTENTIAL FOR MVFR FOG
EARLY THURSDAY MORNING. YET POTENTIAL REMAINS LOW AT THIS TIME
THUS WILL MAINTAIN VFR CONDITIONS AT KCHS AND MARGINAL MVFR
VISIBILITIES WHERE RAIN HAD ALREADY OCCURRED AT KSAV.

EXTENDED AVIATION OUTLOOK...MVFR/IFR POSSIBLE IN SCATTERED SHOWERS
AND STORMS THU AFTERNOON AND EVENING. OTHERWISE VFR CONDITIONS WILL
PREVAIL.

&&

.MARINE...
S/SW WINDS WILL LIKELY SURGE AGAIN TNGT INTO TMRW MRNG AS THE PRES
GRADIENT TIGHTENS A BIT WITH AN INLAND TROF OF LOW PRES MOVING TO
THE COAST AND GRADUALLY OFFSHORE. HOWEVER...EARLY THUNDERSTORMS
COULD DELAY THE SURGE FOR A TIME THIS EVENING. SUSTAINED SPEEDS
MAY NUDGE CLOSER TO 20 KT...INCLUDING AN OCNL GUST OVER 20
KT...BUT CONDITIONS ARE EXPECTED TO REMAIN BELOW SCA LEVELS AS A
WHOLE AND SEAS REMAINING CAPPED AT 4 FT.

THE DIURNAL SEABREEZE CIRCULATION WILL AGAIN DOMINATE THU WITH
ATLC HIGH PRESSURE PERSISTING WELL E OF THE CHS MARINE AREA AND A WEAK
TROUGH OF LOW PRES REMAINS OVER LAND. SW WINDS LESS THAN 15 KT IN
THE MORNING WILL BACK TO S IN THE AFTERNOON...INCREASING TO NEAR 15
KT...THEN WILL RETURN TO SW IN THE EVENING AND OVERNIGHT WHILE
REDUCING BACK TO THE 10-15 KT RANGE. SEAS WILL CONTINUE TO REMAIN
BELOW 4 FT. AS ANOTHER TROUGH OF LOW PRESSURE ADVANCES THROUGH THE
WATERS THU NIGHT...WINDS WILL VEER TOWARD THE W AND WILL DIMINISH
TO 10 KT OR LESS LATE.

AN EXPANSIVE RIDGE FRI THROUGH MON WILL MAINTAIN SOUTH TO SOUTHWEST
WINDS ACROSS THE WATERS WITH SPEEDS GENERALLY LESS THAN 10 KT AND
SEAS LESS THAN 3 FT. A WEAK SEABREEZE SHOULD PUSH WINDS CLOSER TO 10
KT RIGHT ALONG THE COAST EACH AFTERNOON.

&&

.CHS WATCHES/WARNINGS/ADVISORIES...
GA...NONE.
SC...NONE.
