AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
352 PM EDT MON JUN 29 2009
.SYNOPSIS...
A COLD FRONT WILL SHIFT OVER THE REGION THIS EVENING AND THEN
OFFSHORE TONIGHT. THE FRONT WILL SETTLE S OF THE AREA TUE-WED AS A
NOTICEABLY DRIER AIRMASS ENVELOPS THE AREA. A TROUGH OF LOW
PRESSURE WILL PERSIST AT THE SURFACE AND ALOFT THROUGH EARLY NEXT
WEEK.
&&
.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
A COLD FRONT WILL SHIFT THROUGH SOUTHEAST SOUTH CAROLINA AND
SOUTHEAST GEORGIA EARLY TONIGHT AND THEN OFFSHORE BY TOMORROW MORNING.
ATMOSPHERIC MOISTURE AHEAD OF THIS FRONT REMAINS HIGH OVER
SOUTHEAST WITH SFC DEWPTS IN THE LOW TO MID 70S AND PWATS BETWEEN
1.5 TO 2 INCHES. WITH HIGH MOISTURE PRESENT...A CHANCE OF
THUNDERSTORMS WILL REMAIN IN THE FORECAST THIS EVENING AND EARLY TONIGHT...
ESPECIALLY FOR AREAS SOUTH OF THE SAVANNAH RIVER IN SOUTHEAST
GEORGIA. A SLIGHT CHANCE OF THUNDERSTORMS REMAINS NEAR THE SC
COASTLINE.
THUNDERSTORMS WILL SHIFT EAST INTO SOUTHEAST GA ALONG THE COLD FRONT
THIS EVENING...MAINLY FOR AREAS SOUTH OF SAVANNAH GA. THINKING AT
THIS TIME IS SHOWER ACTIVITY WILL BEGIN BY 4 PM WITH A BULK OF THE
THUNDERSTORM ACTIVITY OCCURRING AROUND 6 PM FOR MOST AREAS IN
SOUTHEAST GEORGIA. AN ISOLATED SEVERE THUNDERSTORM THREAT WILL
EXIST THIS EVENING AS THE COLD FRONT PUSHES TOWARDS THE ATLANTIC
COAST AND ENCOUNTERS SFC BASED CAPE BETWEEN 3000 TO 4000 J/KG IN
GA. MARGINAL SHEAR AND WEAK MID LVL LAPSE RATES SUGGESTS STORMS
THAT ARE PULSE TYPE IN NATURE...WITH SMALL HAIL...DOWNBURSTS AND
HEAVY RAIN BEING THE PRIMARY CONCERNS. THUNDERSTORM ACTIVITY WILL
DIMINISH BY MIDNIGHT AS THE FRONT PUSHES OFFSHORE AND SFC HEATING
IS LOST. OVERNIGHT LOWS WILL BE AROUND 70 AS DRYER AIR BEGINS TO
PUSH INTO THE SOUTHEAST.
THE PRESENCE OF SFC DEWPTS IN THE MID 70S AHEAD OF THE COLD FRONT
AND SFC TEMPS IN THE LOW TO MID 90S...WILL CONTINUE TO PRODUCE HEAT
INDICES IN THE 105 TO 110 RANGE OVER PORTIONS OF SOUTHEAST GEORGIA.
THEREFORE...THE HEAT ADVISORY WILL REMAIN IN EFFECT FROM NOON TO 8
PM THIS EVENING AND WILL BE EXPANDED TO INCLUDE AREAS ALONG THE GA
AND SC COASTLINE WITH THE NORTHERN EXTEND INCLUDING BEAUFORT COUNTY.
&&
.SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/...
A TROUGH WILL CONTINUE TO SHIFT OFFSHORE TUESDAY WITH A MUCH DRYER
AIRMASS SHIFTING INTO THE SOUTHEAST TUESDAY AFTERNOON. CONTINUED
WEST NORTHWEST FLOW DURING THE DAY WILL ALLOW FURTHER DRYING OF
THE ATMOSPHERE THROUGH TUESDAY EVENING. DEWPTS WILL LOWER TO THE UPPER
50S OVER INLAND PORTIONS OF SC AND GA...WELL BELOW THE AVG FOR
THIS TIME OF YEAR. STRONG SFC HEATING WILL ALLOW TEMPS TO REACH
THE MID 90S OVER MOST OF THE CWA...EXCEPT FOR THE MID TO UPPER 80S
ALONG THE SC AND GA COASTLINE.
&&
.LONG TERM /WEDNESDAY THROUGH MONDAY/...
WEDNESDAY AND THURSDAY...EXPECT A CONTINUATION OF HOT
TEMPERATURES...WITH HIGHS IN THE MID TO UPPER 90S...ACCOMPANIED BY
UNSEASONABLY LOW DEWPOINTS/RELATIVE HUMIDITY. THUS...THE PROSPECTS
FOR DIURNAL THUNDERSTORMS WILL REMAIN VERY LOW...MAINTAINED THE
ONGOING RAIN-FREE FORECAST FOR WEDNESDAY AND LOWERED POPS TO BELOW
15 PERCENT/REMOVED POPS THURSDAY. LATE WEEK INTO NEXT WEEKEND...LOW
LEVEL MOISTURE SHOULD INCREASE AND THE PROSPECTS FOR A PROGRESSIVE
SEA BREEZE WILL INCREASE...THUS THE CHANCE FOR DIURNAL SHOWERS/
THUNDERSTORMS SHOULD INCREASE A BIT EACH DAY...JUSTIFYING SLIGHT
CHANCE POPS FRIDAY AND THE FOURTH OF JULY. BY LATE NEXT WEEKEND AND
EARLY NEXT WEEK...AS THE ATLANTIC RIDGE EXPANDS OVER THE SOUTHEAST...
DEEPER MOISTURE COULD POOL SOUTH OF A SYNOPTIC DEWPOINT BOUNDARY
LOCATED NORTH OF THE REGION...AND THE POTENTIAL FOR
SHOWERS/THUNDERSTORMS COULD INCREASE.
&&
.AVIATION /20Z MONDAY THROUGH SATURDAY/...
MAIN CONCERN TODAY WILL BE THUNDERSTORM DEVELOPMENT OVER THE SAV
TERMINAL. INTRODUCED TEMPO MVFR CONDITIONS BETWEEN 20Z AND 00Z
THIS EVENING IN RESPONSE TO UNSTABLE CONDITIONS NEAR THE TERMINAL
ALONG WITH THE EXPECTED TIMING OF THE FRONT PUSHING THROUGH THE
AREA. WEST WINDS AROUND 10 KNOTS WILL BECOME SOUTHWEST THIS
EVENING AS THE PROCESS UNFOLDS. CONDITIONS ARE EXPECTED TO REMAIN
DRY AT THE CHS TERMINAL THROUGH THE FIRST 24 HOURS.
WEST WINDS AT OR BELOW 10 KNOTS WILL DEVELOP TUESDAY MORNING AT
BOTH TERMINALS AS A MUCH DRYER AIRMASS PUSHES INTO THE SOUTHEAST.
CLOUDS WILL DECREASE IN COVERAGE THROUGH 15Z TUESDAY. SOME HIGH
CLOUDS WILL PUSH INTO THE REGION IN THE AFTERNOON.
EXTENDED AVIATION OUTLOOK...MAINLY VFR CONDITIONS ARE EXPECTED TO
PREVAIL...ALTHOUGH THERE MAY BE SOME AFTERNOON/EVENING CONVECTION
ON FRIDAY.
&&
.MARINE...
A COLD FRONT FROM THE NORTHWEST WILL SHIFT OVER THE SOUTHEAST THIS
EVENING AND INTO THE ATLANTIC COASTAL WATERS TONIGHT. OVERALL...
LITTLE CHANGE IN TEMPS WILL OCCUR AS THIS FRONT PUSHES THROUGH THE
REGION. AS THE FRONT APPROACHES THE WATERS THIS EVENING...A CHANCE
OF THUNDERSTORMS IS POSSIBLE AS CONDITIONS REMAIN VERY WARM AND
MOIST IN THE BOUNDARY LAYER. WINDS AND SEAS WILL REMAIN WELL BELOW
SCA CRITERIA OUTSIDE OF ANY THUNDERSTORMS. SEAS OF 2 TO 3 FT AND
WINDS BETWEEN 10 TO 15 KTS ARE LIKELY WITHIN 20 NM OF THE SC AND
GA COASTS. 3 TO 4 FT SEAS WITH WINDS BETWEEN 15 TO 20 KNOTS ARE
LIKELY IN THE OUTER GA WATERS OVERNIGHT.
THE FRONT WILL THEN CLEAR THE COASTAL WATERS LATE TONIGHT AND
TUESDAY. WINDS AND SEAS WILL LOWER SLIGHTLY BEFORE BUILDING AGAIN
TUESDAY NIGHT. SCA CRITERIA IS NOT ANTICIPATED THROUGH TUESDAY NIGHT.
BETWEEN A PERSISTENT INLAND SURFACE TROUGH AND ATLANTIC HIGH
PRESSURE CENTERED WELL SE OF THE COASTAL WATERS...CONDITIONS WILL
REMAIN FAVORABLE FOR NOCTURNAL SURGES OF SW WINDS
APPROACHING/EXCEEDING SMALL CRAFT ADVISORY THRESHOLDS WED NIGHT...
ESPECIALLY BEYOND 20 NM...THROUGH THE FORECAST PERIOD. OUTSIDE OF
THESE NIGHTTIME SURGES OF STRONGER WINDS...WINDS/SEAS WILL REMAIN
BELOW SCA LEVELS THROUGH NEXT WEEKEND. DURING THE DAY...A
PREVAILING OFFSHORE FLOW AROUND MIDWEEK WILL TRANSITION TO A MORE
TYPICAL LATE MORNING TO EARLY EVENING SEA BREEZE PATTERN LATE WEEK
INTO NEXT WEEKEND.
