AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
141 PM EDT FRI OCT 31 2008

.SYNOPSIS...
HIGH PRESSURE WILL PERSIST THROUGH EARLY SUNDAY BEFORE A COASTAL
LOW PRESSURE SYSTEM AFFECTS THE AREA LATE SUNDAY INTO WEDNESDAY.
WEAK HIGH PRESSURE WILL BUILD BACK IN LATE NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
DEEP LAYERED RIDGE AXIS WILL REMAIN ELONGATED SW-NE FROM THE
LOWER GULF STATES TO THE MID ATLC REGION TODAY. THICKNESSES FROM
12Z SOUNDINGS INDICATE THE FORECAST IS RIGHT ON TRACK WITH HIGHS
IN THE UPPER 60S TO AROUND 70 VERY FEASIBLE UNDER MOSTLY SUNNY OR
SUNNY SKIES.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/...
UPPER LEVEL DISTURBANCE DESTINED TO BE OUR NEXT RAINFALL PRODUCER
WILL BE DIGGING SSE TOWARD SW MISSISSIPPI BY LATE TONIGHT. MODELS
SUGGEST INCREASING POSITIVE ISENTROPIC ASCENT ON THE 290-295K
SURFACES IN SE GEORGIA WITH A SHARP ATLC MOISTURE GRADIENT NUDGING
E TOWARD THE COAST AS WELL. WE HAVE SHOWN A MODEST INCREASE IN
CLOUDS TO THE E OF I-95 IN GEORGIA TONIGHT AND MAINTAINED A
RAIN-FREE FORECAST EVEN THOUGH A FEW SHOWERS COULD BE BREAKING OUT
OVER THE ADJACENT COASTAL WATERS. AREAS FROM MILLEN AND SYLVANIA TO
ALLENDALE OVER TO JAMESTOWN SHOULD SEE STRONG RADIATIONAL COOLING
AND WITH THE POSITION OF THE SURFACE HIGH AND NEAR CALM WINDS...
THERE IS NO REASON TO DOUBT AT LEAST PATCHY FROST DEVELOPS FAR
INLAND ONCE AGAIN EARLY SAT MORNING.

&&

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
MEDIUM RANGE GUIDANCE IS IN GOOD AGREEMENT THROUGHOUT THE EXTENDED
PERIOD THIS MORNING. THE GFS/ECMWF/CANADIAN ALL SHOW AN UPPER LEVEL
LOW CURRENTLY OVER THE NATIONS MID SECTION PUSHING INTO THE NORTHERN
GULF OF MEXICO OVER THE WEEKEND...THEN LIFTING NORTHEASTWARD OFF THE
COAST OF THE SOUTHEAST UNITED STATES EARLY NEXT WEEK. AT THE
SURFACE...HIGH PRESSURE WILL LOSE ITS INFLUENCE OVER THE REGION OVER
THE WEEKEND AS A COASTAL TROUGH BEGINS TO DEVELOP OFF THE COAST OF
THE SOUTHEAST UNITED STATES. INITIALLY...EXPECT LOW LEVEL WINDS TO
REMAIN PARALLEL TO THE COAST AND THIS SHOULD KEEP SHOWERS FROM
IMPACTING THE FORECAST AREA SATURDAY. AS LOW LEVEL STEERING FLOW
BEGINS TO SHIFT A BIT MORE NORTHEASTERLY SATURDAY NIGHT AND
SUNDAY...EXPECT A FEW SHOWERS WILL BEGIN TO IMPACT COASTAL
ZONES...WITH HIGHEST PROBABILITIES ACROSS SOUTHEAST GEORGIA WHERE
DEEPEST MOISTURE AND BEST ISENTROPIC ASCENT WILL RESIDE.

GUIDANCE IS IN GOOD AGREEMENT SHARPENING UP THE PRESSURE GRADIENT
SUNDAY NIGHT THROUGH TUESDAY AS HIGH PRESSURE BUILDS NORTH OF THE
AREA AND A WAVE OF LOW PRESSURE DEVELOPS ALONG THE COASTAL TROUGH
OFF THE SOUTH CAROLINA AND GEORGIA COAST. THIS WILL ALLOW FOR
INCREASED ISENTROPIC UPGLIDE OVER THE FORECAST AREA...AND WILL
CONTINUE TO MENTION CHANCE POPS SUNDAY NIGHT THROUGH TUESDAY.

THE AREA OF LOW PRESSURE IS EXPECTED TO CONTINUE TO PULL OFF TO THE
NORTHEAST AND AWAY FROM THE REGION TUESDAY NIGHT...SO WILL TAPER
POPS BACK INTO THE SLIGHT CHANCE/LOW CHANCE RANGE. GUIDANCE HAS
TRENDED DRIER WEDNESDAY WITH THE SYSTEM EXPECTED TO PULL OFF TO
THE NORTHEAST AND AWAY FROM THE AREA. FOR NOW WILL KEEP SLIGHT
CHANCE POPS GOING FOR MAINLY COASTAL SOUTH CAROLINA ZONES...AND GO
WITH A DRY FORECAST ELSEWHERE. HIGH PRESSURE IS THEN EXPECTED TO
BUILD BACK INTO THE REGION WEDNESDAY NIGHT AND THURSDAY...WITH RAIN
FREE WEATHER ANTICIPATED.

&&

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
VFR CONDITIONS WILL CONTINUE THROUGH THE PERIOD. AS HIGH PRESSURE
TO THE NORTH EXTENDS NE...THE FLOW WILL EVENTUALLY BECOME MORE
MOIST OVER SAV WITH SOME 4-5 KFT STRATOCU MOVING IN BY DAYBREAK
SAT.

EXTENDED AVIATION OUTLOOK...MVFR OR LOWER CIGS/VSBYS POSSIBLE
SUN NIGHT THROUGH WED...OTHERWISE VFR.

&&

.MARINE...
SURFACE FEATURES ARE NOT EXPECTED TO CHANGE MUCH TODAY AND TONIGHT
AS THE RIDGE REMAINS IN CONTROL. WITHIN 20 NM...A MORNING SURGE WILL
RELAX THIS AFTERNOON FOR ALL WATERS WITH THE EXCEPTION OF OUR GRAYS
REEF AND SABSOON REGIONS WHERE THE PRES GRADIENT IS FORECAST TO
REMAIN THE TIGHTEST. WITH STRONG PERSISTENCE WE HAVE CONTINUED OUR
SMALL CRAFT ADVISORY FOR OUR 20-60 NM GEORGIA WATERS THROUGH
TONIGHT. 00Z WAVEWATCH GUIDANCE BACKS SEAS OFF A TAD LATE TODAY
AND THIS EVENING BEFORE SHOWING INCREASES TOWARD DAWN ON SAT. WITH
NE WINDS AROUND 20 KT MUCH OF THE TIME...WE HAVE MAINTAINED A 4-6 FT
SEA HEIGHT FORECAST.

HIGH PRESSURE WILL WEAKEN OVER THE WATERS THIS WEEKEND AS A COASTAL
TROUGH BEGINS TO DEVELOP OFF THE SOUTH CAROLINA AND GEORGIA COAST.
SEAS MAY REMAIN IN THE SMALL CRAFT RANGE THROUGH EARLY SATURDAY
MORNING ACROSS THE OUTER GEORGIA WATERS...OTHERWISE WINDS AND SEAS
SHOULD REMAIN BELOW SMALL CRAFT THRESHOLDS SATURDAY THROUGH SATURDAY
NIGHT. THE GRADIENT WILL TIGHTEN EVEN FURTHER SUNDAY THROUGH TUESDAY
AS HIGH PRESSURE BUILDS NORTH OF THE AREA AND A WAVE OF LOW PRESSURE
DEVELOPS ALONG THE COASTAL TROUGH OFF THE COAST OF THE SOUTHEAST
UNITED STATES. SMALL CRAFT ADVISORIES APPEAR LIKELY FOR ALL WATERS
SUNDAY NIGHT THROUGH MONDAY NIGHT AND MAY BE NEEDED AS EARLY AS
SUNDAY AND CONTINUE THROUGH TUESDAY AND BEYOND FOR PORTIONS OF THE
WATERS. ADDITIONALLY GALES ARE NOT OUT OF THE QUESTION IF GRADIENT
TIGHTENS MORE THAN CURRENTLY ANTICIPATED. FOR NOW WILL LEAVE MENTION
OUT OF THE HAZARDOUS WEATHER OUTLOOK AND CONTINUE TO CLOSELY MONITOR
LATEST TRENDS IN MODEL GUIDANCE.
