AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
143 AM EDT SAT MAR 19 2011

.SYNOPSIS...
HIGH PRES WILL GRADUALLY SHIFT S TONIGHT AND SAT. A BACKDOOR COLD
FRONT WILL PUSH S THROUGH THE AREA LATE SAT AND SAT NIGHT. ATLC
HIGH PRES WILL THEN BUILD INTO THE REGION AND PREVAIL THROUGH THE
MIDDLE OF NEXT WEEK. ANOTHER COLD FRONT COULD ADVANCE THROUGH THE
AREA BY LATE NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
THE SEA BREEZE WAS SLOW TO WORK INLAND LATE THIS AFTERNOON AS
OFFSHORE LOW LEVEL WSW SYNOPTIC FLOW KEPT IT MORE OF A RESULTANT
BREEZE ALONG THE SOUTHEAST SOUTH CAROLINA COAST THROUGH MUCH OF
THE AFTERNOON. IT CERTAINLY WARMED UP TODAY WITH HIGHS IN THE MID
80S SEEN IN MANY AREAS.

DEEP LAYERED RIDGING WILL PERSIST OVERNIGHT WITH CLEAR SKIES.
BOUNDARY LAYER FLOW IS FORECAST TO SLOWLY VEER TO WNW BY DAWN
ON SAT AS A TROUGH MOVES THROUGH THE MID ATLC REGION. LIGHT
SURFACE WINDS WILL PERSIST OVERNIGHT ACROSS THE FORECAST AREA.
POTENTIAL FOR FOG APPEARS LOW WITH THE ENHANCED LOW LEVEL GRADIENT
OVERNIGHT AT 925 MB AND VERY DRY AFTERNOON DEW POINTS SEEN ON
REGIONAL OBSERVATIONS. WHILE VERY SHALLOW FOG AND SOME HAZE/SMOKE
ARE POSSIBLE ACROSS THE AREA...THESE ELEMENTS REMAIN TOO LOW
CONFIDENCE TO ADD TO THE FORECAST THIS EVENING.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH MONDAY/...
AHEAD OF AN APPROACHING COLD FRONT...EXPECT ANOTHER UNSEASONABLY
WARM DAY SATURDAY..WITH HIGHS IN THE LOWER TO MID 80S AT MANY
LOCATIONS AWAY FROM THE COAST. HIGHS COULD APPROACH THE RECORD OF
85F AT KCHS...DEPENDING ON THE TIMING OF THE ARRIVAL OF THE SEA
BREEZE AND COLD FRONT.

AHEAD OF THE ADVANCING COLD FRONT...12Z GUIDANCE DEPICTS POOLING OF
PWATS EXCEEDING 1 INCH...AND LOW LEVEL CONVERGENCE COULD SUPPORT
ISOLATED SHOWERS SATURDAY AFTERNOON INTO SATURDAY NIGHT.
HOWEVER...THE LOW LEVEL COLD FRONT WILL PUSH INTO AN UPPER RIDGE
POSITION...REMOVED FROM FROM MID/UPPER LEVEL FORCING/ASCENT...SO
COVERAGE OF PRECIPITATION SHOULD REMAIN SPARSE AT BEST. PER AREA
CONSENSUS...INTRODUCED SLIGHT CHANCE POPS INTO FAR N/INLAND COUNTIES
SATURDAY AFTERNOON AND INTO CENTRAL COUNTIES SATURDAY EVENING. DUE
TO UNCERTAINTY REGARDING COLD FROPA TIMING...ADJUSTMENTS TO POP
TIMING COULD BE REQUIRED WITHIN LATER FORECASTS. FURTHER...
THE PREFRONTAL AIRMASS DESTABILIZES SUFFICIENTLY TO SUPPORT ISOLATED
THUNDERSTORMS SATURDAY AFTERNOON/EARLY EVENING...FEATURING LIFTED
INDICES AND SHOWALTER INDICES BELOW ZERO AND MLCAPES AS HIGH AS
600-1000 J/KG. HOWEVER...SINCE THE SURFACE COLD FRONT COULD ARRIVE
AFTER DIURNAL STABILIZATION HAS BEGUN DURING THE EVENING...OPTED NOT
TO INCLUDE ANY MENTION OF THUNDER WITHIN THIS FORECAST...AND HELD
POPS BELOW 15 PERCENT ACROSS CENTRAL/SOUTHERN COUNTIES AFTER
MIDNIGHT SATURDAY NIGHT.

IN THE WAKE OF THE COLD FRONT...A WEDGE OF HIGH PRESSURE WILL PUSH
LOW CLOUDS AND MUCH COOLER AIR INTO THE FORECAST AREA SATURDAY
NIGHT...AND HIGHS SUNDAY WILL AVERAGE AT LEAST 10-15F COOLER THAN
THOSE OF SATURDAY...RANGING FROM THE MID 60S NORTH TO THE LOWER/MID
70S NEAR THE ALTAMAHA RIVER. THEN...THE WEDGE WILL WEAKEN AND THE
UPPER RIDGE WILL BUILD...ALLOWING TEMPERATURES WILL RECOVER TO
75-80F AWAY FROM THE COAST MONDAY. DURING THE TRANSITION...WEAK
ISENTROPIC ASCENT COULD SUPPORT A FEW SHOWERS...BUT POPS REMAIN MUCH
TOO LOW TO JUSTIFY A MENTION OF PRECIP WITHIN PUBLIC FORECASTS.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
ATLC HIGH PRESSURE WILL MAINTAIN ITS INFLUENCE OVER THE AREA MON
NIGHT THROUGH WED WHILE UPPER LEVEL RIDGING CENTERED OVER THE
WESTERN GOMEX EXTENDS E AND NE. THIS WILL PROMOTE RAIN-FREE
CONDITIONS ALTHOUGH THERE WILL BE SOME DIURNAL CUMULUS DEVELOPMENT
MID AND HIGH CLOUDS DUE TO AN APPROACHING STORM SYSTEM BY MIDWEEK.
THE RIDGING WILL ALLOW FOR MAX TEMPS AROUND 80F TUE AND WED. MODELS
STILL INDICATE A COLD FRONT COULD PUSH THROUGH THE REGION THU. WITH
BETTER MODEL AGREEMENT ON THIS SCENARIO...MAINTAINED SLGT CHC POPS
ASSOCIATED WITH COLD FROPA. HAVE ALSO SHOWED A DROP IN TEMPS AND A
CORRESPONDING INCREASE IN CLOUD COVER.

&&

.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...
A 25-30 KT LOW LEVEL JET AND LESS AVAILABLE MOISTURE WITHIN THE
BOUNDARY LAYER WILL PREVENT ANY LIGHT FOG AT THE TERMINALS THIS
MORNING. INSTEAD WE HAVE ADDED WIND SHEAR AT KCHS THROUGH
14Z...WITH WIND DIFFERENTIAL AT KSAV TO REMAIN JUST BELOW THE
VECTOR 20 KT CRITERIA.

A BACK DOOR COLD FRONT WILL PUSH THROUGH THE TERMINALS LATE TODAY
AND EARLY TONIGHT...ACCOMPANIED BY A SCT-BKN DECK AROUND
4500-5000 FT. ANY RISK OF SHRA IS EXTREMELY LIMITED. LIGHT SW AND
WEST WINDS PRIOR TO DAYBREAK WILL VEER AROUND TO NORTH AND NW BY
LATE MORNING...THEN TO THE NE THIS AFTERNOON. NE AND EAST WINDS
WILL THEN BECOME GUSTY BEGINNING AROUND 20-21Z WITH DEEPENING
ONSHORE FLOW IN ASSOCIATION WITH THE COLD FRONT AND THE SEA
BREEZE.

EXTENDED AVIATION OUTLOOK...MAINLY VFR WEATHER WILL PREVAIL.

&&

.MARINE...
THE MARINE ZONES ARE LOCATED BETWEEN A SURFACE TROUGH TO THE
N AND HIGH PRES SLIPPING S. AS A RESULT...EXPECT WIND SPEEDS TO
REMAIN CLOSE TO THE 15 KT RANGE OVERNIGHT. S TO SW DIRECTION ARE
EXPECTED TO GRADUALLY VEER TO A MORE W COMPONENT BY DAYBREAK. SEAS
ARE AVERAGING 2-3 FT AND EXPECTED TO UNDERGO LITTLE CHANGE
OVERNIGHT.

OFFSHORE WINDS WILL GIVE WAY TO A WEAKENING PRESSURE GRADIENT AND A
DOMINANT SEA BREEZE CIRCULATION AHEAD OF AN APPROACHING COLD FRONT
SATURDAY AFTERNOON. THEN...A STRONG BACK DOOR COLD FRONT WILL PUSH
THROUGH THE COASTAL WATERS AND WILL USHER A SURGE OF SMALL CRAFT
ADVISORY WINDS/SEAS INTO THE REGION. COLD FROPA/DETERIORATION COULD
BEGIN ACROSS NORTHERN WATERS BY LATE SATURDAY AFTERNOON...BUT SMALL
CRAFT ADVISORY CONDITIONS APPEAR MORE LIKELY SATURDAY NIGHT. GIVEN
LINGERING UNCERTAINTY REGARDING FROPA TIMING...OPTED NOT TO RAISE
ANY SMALL CRAFT ADVISORIES WITHIN THE FRIDAY AFTERNOON FORECAST
PACKAGE.

WITH STRONG HIGH PRESSURE CENTERED N/NE OF THE WATERS...A TIGHT
SURFACE PRESSURE GRADIENT WILL MAINTAIN GENERAL SMALL CRAFT ADVISORY
CONDITIONS THROUGH SUNDAY. THEN...CONDITIONS WILL BEGIN TO IMPROVE
AS THE CENTER OF HIGH PRESSURE SHIFTS TOWARD THE S SUNDAY
NIGHT...ALTHOUGH SCA SEAS WILL PERSIST ACROSS THE OUTER GA WATERS
INTO MONDAY. THEN...WINDS/SEAS WILL REMAIN BELOW SCA THRESHOLDS
THROUGH MIDWEEK AS HIGH PRESSURE SHIFTS E/SE OF THE WATERS.

RIP CURRENTS...MODERATE TO STRONG EAST TO NE WINDS AND LARGER
SURF...COMBINED WITH THE RECENT PROXIGEAN SPRING TIDE AND THE
VERNAL EQUINOX...WILL LEAD TO AN ENHANCED RISK OF RIP CURRENTS
SUNDAY.

FOR INFORMATION PURPOSES...THE PROXIGEAN SPRING TIDE WILL OCCUR
SATURDAY. THE PROXIGEAN SPRING TIDE OCCURS AS A RESULT OF THE FULL
MOON...THE LUNAR PERIGEE AND THE YEARS CLOSEST APPROACH OF THE
MOON TO THE EARTH /CALLED THE PROXIGEE/. THIS YEAR THEY ALL OCCUR
WITHIN ABOUT AN HOUR OF EACH OTHER. THIS WILL CAUSE LARGER THAN
NORMAL VARIATION IN TIDES FROM THEIR HIGH TO LOW VALUES IN THE
TIDAL CYCLE FOR AT LEAST THE NEXT FEW DAYS.

&&

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