AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
135 AM EDT SUN AUG 5 2012

.SYNOPSIS...
ATLANTIC HIGH PRESSURE WILL PREVAIL INTO EARLY NEXT WEEK. AN
APPROACHING COLD FRONT WILL STALL AND WEAKEN TO THE NORTHWEST
DURING THE MID TO LATE WEEK PERIOD.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
MADE SOME PRETTY SUBSTANTIAL CHANGES TO THE SKY FORECAST FOR THE
REST OF TONIGHT WITH MAINLY CLEAR SKIES BEING OBSERVED ACROSS MUCH
OF THE REGION. DO EXPECT AN INCREASE IN CLOUD COVER LATER TONIGHT
AS LOW-LEVEL CONVERGENCE INCREASES ALONG THE COAST AND WITH IT
SHOWER ACTIVITY. LOWS FROM THE LOWER 70S WELL INLAND TO THE LOWER
80S ON THE BEACHES LOOK ON TRACK.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH TUESDAY/...
A DEEP LAYER RIDGE AXIS WILL CONTINUE TO BE CENTERED JUST NORTH OF
THE REGION THROUGH EARLY MONDAY. THE TROPICAL WAVE THAT HAS BEEN
OVER THE WESTERN BAHAMAS AND INTO CENTRAL AND SOUTHERN FLORIDA IS
FORECAST TO MOVE SLOWLY WNW ACROSS THE CENTRAL FL PENINSULA AND INTO
THE EAST GULF OF MEXICO INTO EARLY NEXT WEEK. THE MAIN IMPACT FROM
THIS SYSTEM WILL BE AN INCREASE IN DEEP LAYER MOISTURE ALONG THE
NORTHERN PERIPHERY OF THE TROPICAL WAVE...ESPECIALLY LATER TONIGHT
AND THROUGH SUNDAY...ESPECIALLY OVER THE SOUTHERN HALF OF THE AREA.
ALL MODELS SHOW PWATS INCREASING TO ABOVE 2.O INCHES SUNDAY. HAVE
NUDGED POPS UP TO HIGH END CHANCE FOR SUNDAY GIVEN THE INCREASE IN
MOISTURE...AND WOULD NOT BE SURPRISED IS POPS NEED TO BE INCREASED
EVEN MORE...ESPECIALLY OVER OUR GA REGION. THINK ATMOSPHERE WILL BE
PRETTY TROPICAL IN NATURE...WITH MORE SHOWERS THAN
THUNDERSTORMS...AT LEAST THROUGH SUNDAY.

BY LATER MONDAY AND TUESDAY...THE DEEP LAYER RIDGE BEGINS TO WEAKEN
AND SHIFT SOUTHWARD OVER THE SOUTHERN FORECAST AREA AS A BROAD UPPER
TROUGH DEVELOPS ACROSS THE GREAT LAKES STATES AND NEW ENGLAND. HAVE
CONTINUED CHANCE/CLIMO POPS MONDAY AND TUESDAY...WITH THE BEST
CONCENTRATION OF CONVECTION BEING FOCUSED INLAND DURING THE
AFTERNOON AND EVENING...DESPITE INDICATION BY NAM AND GFS QPF FIELDS
THAT PRECIP COULD CARRY THROUGH MONDAY NIGHT INLAND AS A WEAK FRONT
STALLS WELL NW OF THE AREA.

MADE ONLY COSMETIC CHANGES TO TEMPS...WITH BOTH MAXES AND MINS RIGHT
AROUND NORMAL TO POSSIBLY A TAD BELOW NORMAL...ESPECIALLY SUNDAY.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
UPPER LEVEL RIDGING WILL CONTINUE TO WEAKEN THROUGH THE MID TO
LATE WEEK PERIOD...AS A TROUGH ALOFT AND SEVERAL SHORTWAVES MOVE
ACROSS THE NEW ENGLAND STATES. A COLD FRONTAL SYSTEM IS EXPECTED
TO STALL AND EVENTUALLY DISSIPATE WEST OF THE AREA BY THE MIDDLE
OF NEXT WEEK. ALTHOUGH ATLANTIC SURFACE HIGH PRESSURE WILL AT
LEAST MAINTAIN CONTROL OF THE COASTAL AREAS THROUGH THE EXTENDED
PERIOD...THE SURFACE PATTERN FARTHER INLAND WILL BE MORE ILL
DEFINED BETWEEN HIGH PRESSURE OVER THE CENTRAL UNITED STATES AND
THE SUBTROPICAL HIGH JUST TO THE EAST. CONSIDERING THE INCREASED
FORCING FROM THE STALLED FRONT TO THE WEST...COMBINED WITH
INFLUENCES FROM WEAK SHORTWAVE ENERGY JUST INLAND AND TYPICAL
BOUNDARY/SEABREEZE INTERACTIONS...SOLID SHOWER/THUNDERSTORM
CHANCES CONTINUE THROUGH FRIDAY. TEMPERATURES WILL CONTINUE TO
REFLECT NEAR SEASONAL NORMALS...WITH HIGH TEMPERATURES IN THE LOW
TO MID 90S DURING THE AFTERNOON FALLING INTO THE LOW TO MID 70S
OVERNIGHT.

&&

.AVIATION /06Z SUNDAY THROUGH THURSDAY/...
LOW-MEDIUM CONFIDENCE ON MOST ELEMENTS AT BOTH TERMINAL FOR THE
NEXT 24 HOURS.

KCHS...EXPECT TO SEE AN EXPANSION OF LOW CLOUDS AFTER 09Z AS LOW-
LEVEL SPEED CONVERGENCE INCREASES ALONG THE COAST. BEST CHANCES
FOR MVFR CIGS WILL BE FROM 12-15Z COINCIDENT WITH THE STRONGEST
CONVERGENCE. ISOLATED-SCATTERED SHOWERS ARE EXPECTED TO DEVELOP
AFTER SUNRISE AND MOVE INLAND. GIVEN THE FAST FLOW ALOFT RESIDENCE
TIME OF ANY SUB-VFR REDUCTIONS IN VSBYS WILL BE BRIEF THUS WILL
NOT INCLUDE ANY TEMPO OR PREVAILING REDUCTIONS ATTM. BEST SHOWER
ACTIVITY IS FORECAST TO CONCENTRATE WELL SOUTH OF THE TERMINAL
LATER TODAY AND CONTINUE INTO TONIGHT.

KSAV...STARTING TO SEE AN UPTICK IN SHOWER ACTIVITY OFFSHORE AS
LOW-LEVEL CONVERGENCE BUILDS ALONG THE COAST. COULD SEE A BRIEF
SHOWER AT JUST ABOUT ANY TIME PRIOR TO SUNRISE...BUT ANY VSBY
REDUCTIONS SHOULD BE BRIEF. THERE WILL ALSO BE A INCREASED RISK
FOR MVFR CIGS PRIOR TO DAYBREAK AND THE 06Z TAF WILL REFLECT THIS.
EXPECT TO SEE A QUICK EXPANSION IN SHOWER ACTIVITY AFTER SUNRISE
WITH COVERAGE BECOMING SCATTERED-NUMEROUS. WINDOW FOR THE BEST
CHANCES FOR ANY MEANINGFUL IMPACTS WILL BE 15-18Z WHERE MVFR
VSBYS/CIGS WILL BE POSSIBLE IN MODERATE RAINFALL. QUICK DURATIONS
OF IFR OR LOWER ARE A POSSIBILITY BUT THE RISK/SPATIAL AREA IS TOO
LOW TO JUSTIFY A MENTION ATTM. SHOWER ACTIVITY IS EXPECTED TO END
BY EARLY AFTERNOON.

EXTENDED AVIATION OUTLOOK...NO CONCERNS.

&&

.MARINE...
TONIGHT...MODERATE SOUTHEAST FLOW WILL DOMINATE AS A TROPICAL WAVE
PUSHES INLAND ACROSS FLORIDA. WINDS WILL GENERALLY REMAIN 15
KT OR LESS BUT COULD AT LEAST GUST TO 20 KT AT TIMES. SEAS WILL
BUILD SLIGHTLY...MAINLY DUE TO AN INCREASE IN EASTERLY
SWELL...BUT SHOULD GO NO HIGHER THAN 5 FT. THUS...CONDITIONS
SHOULD REMAIN BELOW ADVISORY LEVELS.

SUNDAY THROUGH THURSDAY...NO HIGHLIGHTS FOR WINDS AND SEAS
EXPECTED THROUGH THE PERIOD AS THE ATLANTIC RIDGE OF HIGH PRESSURE
REMAINS OVER THE REGION THROUGH MONDAY. BY TUESDAY AND
BEYOND...THE RIDGE WEAKENS AND MOVES OFF TO THE SOUTHEAST AS A
TROUGH OF LOW PRESSURE DEVELOPS INLAND. A TROPICAL WAVE WILL
REMAIN WELL SOUTH OF THE AREA THROUGH EARLY NEXT WEEK.
HOWEVER...EXPECT AN INCREASE IN SHOWERS AND ISOLATED THUNDERSTORMS
TONIGHT THROUGH SUNDAY AS DEEPER MOISTURE ALONG THE NORTHERN
PERIPHERY OF THE TROPICAL WAVE MOVES ACROSS THE AREA. A RETURN TO
MORE ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS... MAINLY
DURING THE LATE NIGHT AND MORNING...BY TUESDAY AND BEYOND.
DEPENDING ON HOW STRONG THE TROPICAL WAVE GETS WELL SOUTH OF THE
REGION...WILL GOVERN THE STRENGTH OF THE WINDS... ESPECIALLY
SUNDAY OVER THE SOUTHERN/GA WATERS. FOR NOW...HAVE KEPT WINDS AT
15 KT OR LESS AND SEAS 5 FEET OR LESS THROUGH THE PERIOD.

GA...NONE.
