AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
1105 AM EDT MON JUN 11 2007

.SYNOPSIS...
A WEAK FRONTAL BOUNDARY WILL REMAIN JUST S OF THE AREA THROUGH TUE
MORNING. A SERIES OF UPPER LEVEL DISTURBANCES WILL SWING ACROSS
THE AREA THROUGH THU FROM THE NW WHICH WILL BRING AN INCREASING
CHANCE OF SHOWERS AND THUNDERSTORMS THROUGH THE MIDDLE OF THE WEEK.
DRIER CONDITIONS WITH TEMPERATURES NEAR NORMAL ARE EXPECTED FOR
THE END OF THE WEEK AS HIGH PRESSURE RETURNS.

&&

.NEAR TERM /THROUGH TONIGHT/...
SFC FRONTAL BNDRY FEATURE HAS DRIFTED S TO ALIGN ITSELF ALONG THE
GA/FL BORDER WHILE A WEAK MESOLOW HAS DEVELOPED OVER THE ERN GULF
COAST. ON WV IMAGERY...A PAIR OF UPR LVL DISTURBANCES CAN BE
SEEN...A MORE PROMINENT ONE OVER THE MID ATLC STATES SINKING SWD
AND ANOTHER WEAKER ONE OVER THE GULF COAST STATES. AM QUITE
CONCERNED ABOUT THE HIGH DEWPOINTS SEEN OVER SE GA...SOME OF WHICH
HAVE REACHED AS HIGH AS 79 THIS MRNG BUT ARE NOW MORE COMMONLY IN
THE MID 70S...WHILE SE SC IS IN THE UPR 60S TO ARND 70. A SHARP
DEWPOINT BNDRY CAN BE DELINEATED NEAR THE NC/SC BORDER WITH
DEPOINTS IN THE UPR 50S TO LOWER 60S IN THAT REGION. THUS... THE
CHS CWFA IS SQUARELY WITHIN A HIGH DEWPOINT AND HIGH INSTABILITY
REGION WITH DECENT JETTING AND UPR LVL SHORTWAVES APPROACHING.
THIS MIXTURE ADDS UP TO AT LEAST MID RANGE CHC POPS WITH A SLIGHT
CHC FOR SEVERE WX. PER THE MODIFIED 12Z KCHS RAOB...PWATS ARE NEAR
2 INCHES...LI -5.9...CAPES OVER 2500 J/KG WITH A SFC TEMP OF 85
AND 0-3KM CAPE OF 177. THE CAP IS ALSO MUCH WEAKER TDA AND 0-3KM
CAPE IS HIGHER...THUS LEADING TO A DECENT CHANCE FOR SEVERE WX.
MAIN HAZARDS WILL AGAIN BE DAMAGING WINDS VIA MICROBURSTS AND
LARGE HAIL VIA THE COOLING AND MORE MOIST MIDLVLS. GIVEN THAT
EXTENSIVE CLOUD COVER IS PLAGUING THE AREA THIS MRNG...AM NOT
COMPLETELY BUYING OFF ON SEVERE BUT WITH AT LEAST MODERATE
CONFIDENCE WILL ADD SMALL HAIL AND GUSTY WIND WORDING TO THE
GRIDDED AND TEXT PRODUCTS.

TEMPS WILL ALSO BE A BIT TRICKY TDA...WITH THE DEWPOINT GRADIENT
AND SFC BNDRY NEARBY. ANTICIPATED LESSER CLOUD COVER OVER SE GA
FOR THE FIRST HALF OF THE DAY SHOULD LEAD TO MAX TEMPS IN THE
LOWER 90S WHILE SE SC SHOULD HAVE MAX TEMPS IN THE UPR 80S.

&&

.SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/...
TUESDAY SHOULD BE AN INTERESTING DAY WITH SCATTERED TO POSSIBLY
NUMEROUS CONVECTION IN A FAIRLY SHEARED ENVIRONMENT FOR THIS TIME
OF YEAR. SOME INDICATORS SUGGEST HEAVY RAIN CONCERNS...BUT OTHER
PROGS INDICATE A SEVERE/MULTICELL POTENTIAL. WE HAVE MAINTAINED
HIGH CHC POPS MANY AREAS ALONG AND S OF THE SAVANNAH RIVER. ON
WED...THE BULK OF THE STRONG UPPER VORT IS FORECAST TO ROLL THRU
AND ANOTHER UNSETTLED DAY ON TAP. NO CHANGE TO CHCY POPS WITH
HIGHEST CHCS SRN ZONES. MAX TEMPERATURES SHOULD BE CONFINED TO THE
LOW/MID 80S MOST AREAS BOTH TUE AND WED.

&&

.LONG TERM /THURSDAY THROUGH SUNDAY/...
HIGH AMPLITUDE/REX BLOCK PATTERN WILL MAINTAIN A COMBINATION OF
SURFACE HIGH PRES AND MID TO UPPER LEVEL TROUGHING OVER THE REGION
THU THROUGH SAT...WITH A WEAKENING OF THE UPPER TROUGH POSSIBLE
SUN. THE ASSOCIATED THERMAL TROUGH WILL PROVIDE BELOW NORMAL TEMPS
INTO NEXT WEEKEND...WITH NEAR NORMAL TEMPS RETURNING SUN IF THE
THERMAL TROUGH FILLS AS EXPECTED. MEANWHILE...THE SURFACE BOUNDARY
WHICH MAY HAVE CONTRIBUTED TO PERIODS OF ENHANCED PRECIP WILL MOST
LIKELY REMAIN W-S-SE OF THE FCST AREA THU INTO THE WEEKEND.
HOWEVER...COOL TEMPS ALOFT...AND THE POTENTIAL FOR INDIVIDUAL
SHORTWAVES TO PUSH THROUGH THE BASE OF THE PERSISTENT UPPER
TROUGH...SHOULD PRODUCE AT LEAST ISOLD TO SCT DIURNAL
SHOWERS/TSTMS...WITH COVERAGE DEPENDING ON THE ORIENTATION OF THE
UPPER TROUGH AND DEGREE OF SUBSIDENCE/CAPPING...IF ANY...PROVIDED
BY THE LOW LEVEL RIDGE.

&&

.AVIATION /15Z MONDAY THROUGH FRIDAY/...
STRATUS AND IFR CIGS HAVE REMAINED SW OF KSAV EARLY THIS MORNING
AND SHOULD NOT BE MUCH OF A PROBLEM. STRATOCUMULUS ALONG A LOW
LEVEL CONVERGENCE AXIS HAS RECENTLY DWINDLED BTWN KCHS AND KSAV...
BUT SCT CU FIELDS MAY REDEVELOP AT KCHS BY MID MORNING. OCNL MVFR
CIGS PSBL AT KSAV THRU 14Z OR SO. WE BELIEVE THE MOST LIKELY TIME
THAT TSTMS VISIT THE TERMS WILL BE BEYOND 00Z. CHCS ARE MUCH LOWER
THAN LIKELY HOWEVER...SO WILL CONTINUE TO GO WITH ONLY CB MENTIONS
IN THE TAFS.

EXTENDED AVIATION OUTLOOK...PERIODS OF MVFR OR LOWER CONDITIONS
WILL BE POSSIBLE IN SHOWERS/TSTMS...AND IN EARLY MORNING
STRATUS/FOG...ESPECIALLY WHERE RAIN FALLS...TUE THROUGH FRI.

&&

.MARINE...
GENERALLY BENIGN CONDS TO PREVAIL TDA ACRS THE WATERS TDA WITH
HIGH PRES WELL N OF THE WATERS AND A LINGERING FNTL BNDRY S OF THE
WATERS COMBINING FOR A PREVAILING ELY FLOW. WITH A RATHER WEAK
PRES GRADIENT...WINDS OF 10-15 KT WILL PREVAIL BUT THE ONLY AREA
THAT MAY SEE HIGHER SPEEDS IS ALONG THE IMMEDIATE COAST. THE
LAND/SEA INTERFACE KICKED WINDS IN CHAS HARBOR NEAR 20 KT AND WITH
THE ANTICIPATED SEABREEZE...THIS MAY AGAIN BE THE CASE. WILL KEEP
ALL AREAS BELOW SCA LEVELS BUT WILL HOIST AN SCEC FOR CHAS HARBOR.
SEAS TO REMAIN AOB 4 FT.

AS UPPER LOW DROPS OVER THE REGION THE NEXT DAY OR TWO...SURFACE
PRESSURES INCREASE AND A STRONGER E AND NE WIND WILL DEVELOP OVER
THE WATERS WED AND THU. WILL SEE AN INCREASE IN HEIGHTS BUT FOR
NOW HAVE CAPPED THE SEAS AROUND 4 FT. THE NORTHEAST WIND IS
EXPECTED TO CONTINUE THROUGH FRIDAY AS THE SFC HIGH BUILDS OVER
THE SOUTHEAST COASTAL ATLANTIC.

&&

.CLIMATE...
THE MINIMUM TEMPERATURE REPORTED AT KSAV /SAVANNAH INTERNATIONAL
AIRPORT/ THIS MORNING WAS 77 DEGREES. SHOULD THIS HOLD THROUGHOUT
THE DAY TODAY...THIS WOULD BE A RECORD HIGH MINIMUM TEMPERATURE
FOR THE DAY...BREAKING THE RECORD OF 75 SET BACK IN 1952. WILL
HOLD OFF SENDING A RECORD EVENT REPORT UNTIL THE MIDNIGHT CLIMATE
PRODUCTS ARE RUN TO ENSURE THAT A LOWER TEMPERATURE IS NOT REACHED
BEFORE MIDNIGHT AND THE RECORD DOES IN FACT HOLD.

&&

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