AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
136 AM EDT WED OCT 24 2012

.SYNOPSIS...
HIGH PRESSURE WILL PREVAIL ACROSS THE REGION THROUGH LATE WEEK
BEFORE A COLD FRONT APPROACHES FROM THE WEST OVER THE WEEKEND.
MEANWHILE...TROPICAL CYCLONE SANDY IS EXPECTED TO SLOWLY MOVE
NORTH OUT OF THE CARIBBEAN TOWARD THE BAHAMAS AND STRENGTHEN
THROUGH FRIDAY...REMAINING OFFSHORE THROUGH THE WEEKEND.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
RIDGING WILL EXTEND THROUGHOUT THE TROPOSPHERE ATOP THE FORECAST
AREA TONIGHT...AND WE/RE LOOKING AT ANOTHER RAIN-FREE NIGHT WITH
GOOD TO EXCELLENT RADIATIONAL COOLING INLAND. THERE WILL BE
ISENTROPIC UPGLIDE ACROSS OUR COASTAL SE GA AND THE IMMEDIATE
COASTAL SC ZONES...BUT GIVEN THE SHALLOW NATURE OF AVAILABLE
MOISTURE AND THE BOUNDARY LAYER FLOW BACKING TO NE WITH LAND
BREEZE CIRCULATIONS...WE DON/T SEE THIS GENERATING ANYTHING MORE
THAN PATCHY STRATOCUMULUS CLOUDS.

WHEN COMPARING LATE TUESDAY EVENING TEMPS WITH THOSE OF 24 HOURS
AGO WE NOTICE THAT ON AVERAGE WE ARE ABOUT 5-9 DEGREES WARMER.
EVEN SO...THE MOS GUIDANCE HAS BEEN TOO WARM THE PAST FEW NIGHTS
AND WE ANTICIPATE THAT THIS TREND WILL CONTINUE AGAIN TONIGHT WITH
MOSTLY CLEAR CONDITIONS AWAY FROM THE COAST AND CALM OR NEAR CALM
WINDS. THE AIR MASS HAS UNDERGONE AT SOME MODIFICATION SO WE DON/T
FORESEE IT GETTING AS COOL AS RECENT NIGHTS...BUT STILL DROPPING
TO NEAR OR EVEN A BIT BELOW NORMAL AWAY FROM THE SHORELINE
COMMUNITIES. TEMPS WILL RANGE FROM THE UPPER 40S ALONG THE NW
ZONES...THE LOWER AND MIDDLE 50S MOST ELSEWHERE...EXCEPT FOR THE
LOWER AND MIDDLE 60S NEAR AND AT THE COAST WHERE WINDS REMAIN IN
THE 5-10 MPH RANGE.

ONE CONCERN THAT HAS BEEN LACKING OF LATE HAS BEEN THE RISK OF ANY
SIGNIFICANT FOG. DEW POINTS WILL BE A GOOD 5-10 DEGREES HIGHER
LATE TONIGHT COMPARED TO LATE LAST NIGHT...AND THIS INCREASE IN
AVAILABLE MOISTURE AND THE RADIATIONAL COOLING WILL ALLOW FOR PATCHY
FOG...PERHAPS EVEN LOCALLY DENSE FOG TO FORM INLAND FROM US-17.
VISIBILITIES WILL START DROPPING AROUND 2 OR 3 AM AS WE REACH OUR
CROSS-OVER TEMPS IN THE MID AND UPPER 50S AND FSI VALUES FALL TO
15-25. IT STILL LOOKS LIKE THE SOIL IS TOO WARM AND ALSO TOO DRY
FOR ANY AREAS OF DENSE FOG.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH FRIDAY/...
THE UPPER LEVEL RIDGE EXTENDING FROM THE WESTERN GULF TO THE
CAROLINAS AND MID ATLANTIC STATES WILL GRADUALLY WEAKEN THROUGH THE
PERIOD...WHILE SURFACE HIGH PRESSURE ALSO BEGINS TO RETREAT
NORTHWARD THROUGH FRIDAY. WEAK COASTAL TROUGHING AND ASSOCIATED
COASTAL CONVERGENCE COULD INITIALLY BE THE DRIVING FORCE FOR ANY
PRECIPITATION POTENTIAL DURING THE SHORT TERM. FAVORED AREAS FOR ANY
ISOLATED SHOWERS WILL LIKELY BE LIMITED TO THE MARINE ZONES AND
PERHAPS LOCALLY ONSHORE...ESPECIALLY ACROSS SOUTHEAST GEORGIA
COASTAL COUNTIES. ELSEWHERE...LACKING DEEP MOISTURE AS PRECIPITABLE
WATER VALUES GENERALLY AT OR BELOW ONE INCH SUGGEST RAIN CHANCES
WILL BE LESS THAN 15 PERCENT.

PERHAPS OF GREATER CONCERN WILL BE THE STRENGTH AND TRACK OF
TROPICAL CYCLONE SANDY...AS IT LIFTS NORTH FROM THE BAHAMAS BY
FRIDAY. THERE REMAINS ENOUGH DISAGREEMENT BETWEEN THE OPERATIONAL
FORECAST MODELS TO LEND SOME UNCERTAINTY TO THE WINDS AND
PRECIPITATION FORECAST FOR FRIDAY. THERE IS AT LEAST SOME
CONSISTENCY IN INDICATING THE SYSTEM WILL REMAIN TO THE EAST OF THE
FORECAST AREA...AND HAVE DECIDED TO LEAN TOWARD PERSISTENCE BY
KEEPING BEST RAIN POTENTIAL OVER THE WATERS CLOSEST TO THE
WESTERN PERIPHERY OF THE STRENGTHENING SYSTEM.

CONSIDERING RESIDUAL DEEP LAYER RIDGING ACROSS THE AREA...HIGH
TEMPERATURES WILL AVERAGE SEVERAL DEGREES ABOVE SEASONAL NORMALS
WEDNESDAY THROUGH FRIDAY. EXPECT TEMPERATURES TO PEAK IN THE
LOWER 80S EACH AFTERNOON UNDER MAINLY PARTLY CLOUDY SKIES.
STRENGTHENING ONSHORE FLOW WILL ALSO ASSIST IN MODERATING
NIGHTTIME LOWS AS THE WEEK PROGRESSES. LOW TEMPERATURES WILL RANGE
FROM THE MID 50S INLAND TO THE LOWER 60S ALONG THE COAST
WEDNESDAY NIGHT...THEN UPPER 50S TO MID 60S BY THURSDAY NIGHT.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
THE TWO PRIMARY FEATURES IN THE LONGER RANGE FORECAST ARE
TROPICAL CYCLONE SANDY AND AN UPPER TROUGH DIGGING TOWARD THE OHIO
VALLEY. THE EVENTUAL TRACK OF THE PRIMARY UPPER SHORTWAVE WILL
HAVE AN EFFECT ON WHERE SANDY EVENTUALLY GOES. THE ECMWF STILL
SEEMS SPURIOUS WITH THE LONG-RANGE TRACK OF SANDY AND ITS
INTERACTION WITH THE UPPER TROUGH. MAINTAINED A FORECAST ALONG
THE LINES OF THE GFS...WHICH LIFTS THE CYCLONE N AND NE AWAY FROM
THE SOUTHEAST COAST THROUGH EARLY NEXT WEEK. THIS WOULD RESULT IN
MINIMAL PRECIPITATION IN OUR AREA...MAINLY SOME SHOWERS OVER THE
COASTAL WATERS AND SOME LAND AREAS PRIMARILY SATURDAY NIGHT.
ABOVE NORMAL TEMPERATURES WILL PERSIST ON SATURDAY...BUT A STARK
COOL DOWN IS EXPECTED SUNDAY AS A REINFORCING COLD FRONT PUSHES
THROUGH THE REGION.

&&

.AVIATION /06Z WEDNESDAY THROUGH SUNDAY/...
SOME PATCHY LIGHT FOG OR GROUND FOG MAY DEVELOP AROUND EITHER
TERMINAL PRIOR TO DAYBREAK. HOWEVER VSBYS SHOULD NOT BE REDUCED
BELOW 5SM. OTHERWISE VFR CONDITIONS WILL PREVAIL.

EXTENDED AVIATION OUTLOOK...VFR WILL GENERALLY PREVAIL. SMALL
CHANCES FOR MVFR VSBYS AROUND DAYBREAK EACH MORNING.

&&

.MARINE...
TONIGHT...AN EAST TO WEST RIDGE OF SUB-TROPICAL ATLANTIC HIGH
PRESSURE WILL LIE ATOP THE CAROLINAS...WITH ITS ANTICYCLONIC
CIRCULATION ONLY WEAKLY INTERRUPTED BY A TROUGH THAT WILL BE
FOUND ACROSS THE COASTAL WATERS THROUGH THE NIGHT. NE AND EAST
WINDS WILL AVERAGE 12-18 KT ACROSS THE OCEANIC WATERS AND LESS
THAN 5 OR 10 KT IN CHARLESTON HARBOR. OCCASIONAL GUSTS THOUGH WILL
APPROACH 20 KT ACROSS THE GA WATERS WHERE THE GRADIENT IS A LITTLE
TIGHTER. SEAS WILL BE COMPRISED OF BOTH WIND DRIVEN WAVES AND
SWELL WAVES...AVERAGING 2-4 FT...HIGHER AS ONE NAVIGATES FURTHER
FROM SHORE.

HIGH PRESSURE NORTH OF THE WATERS WILL MAINTAIN AN EAST/NORTHEAST
FLOW WEDNESDAY INTO THURSDAY. THE GRADIENT WILL THEN TIGHTEN AS
TROPICAL CYCLONE SANDY LIFTS NORTH FROM THE BAHAMAS...WITH WINDS
INCREASING AND BECOMING NORTH/NORTHEAST FRIDAY THROUGH THE
WEEKEND. THE EVENTUAL TRACK OF SANDY IS QUITE UNCERTAIN GIVEN
SUCH A WIDE SPREAD IN THE SYNOPTIC SCALE MODELS. HAVE BLENDED THE
LATEST NAM AND GFS SOLUTIONS...RESULTING IN ONLY MINOR DIFFERENCES
FROM THE PREVIOUS FORECAST. ADVISORY LEVEL SEAS 6 FT AND GREATER WILL
LIKELY REACH THE OUTER GEORGIA WATERS DURING THE PRE DAWN HOURS
THURSDAY MORNING...WITH BUILDING WAVE HEIGHTS THEN SPREADING NORTH
AND WEST INTO THE NEARSHORE WATERS THROUGH SATURDAY. SURGING
NORTHEAST FLOW INTO SMALL CRAFT ADVISORY RANGE IS EXPECTED ACROSS
NEARLY ALL WATERS BY FRIDAY INTO SATURDAY. CONDITIONS WILL SLOWLY
IMPROVE SUNDAY AS THE GRADIENT BEGINS TO RELAX.

HIGH SURF ADVISORIES LOOK INCREASINGLY LIKELY BEGINNING AS EARLY AS
FRIDAY...YET MORE LIKELY FRIDAY NIGHT OR SATURDAY. WAVE WATCH IS
INDICATING 10 TO 13 FT LONG PERIOD SWELL COMING IN FROM THE
EAST/SOUTHEAST LATER FRIDAY. WITH PERIODS AROUND 14 SECONDS...THIS
WOULD LIKELY TRANSLATE INTO 5 FT OR GREATER BREAKING WAVE HEIGHTS
ALONG THE SHORE. EROSION IS ALSO POSSIBLE...ALTHOUGH THE EXTENT
IS UNCLEAR AT THIS TIME. FINALLY...THE RIP CURRENT RISK WILL BE
ENHANCED THROUGH THE WEEKEND AS THE SWELL STARTS MOVING IN TO THE
REGION.
