AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
1230 PM EST FRI DEC 28 2012

.SYNOPSIS...
HIGH PRESSURE OVER GEORGIA AND SOUTH CAROLINA TODAY WILL GIVE WAY
TO AN ADVANCING LOW PRESSURE SYSTEM THIS EVENING. A COLD FRONT
WILL MOVE THROUGH LATE TONIGHT AND SATURDAY MORNING FOLLOWED BY
HIGH PRESSURE THROUGH MONDAY. ANOTHER FRONT WILL DROP INTO THE
REGION ON TUESDAY WITH SEVERAL WAVES OF LOW PRESSURE MOVING UP THE
COAST ALONG THE FRONT THROUGH THURSDAY. HIGH PRESSURE WILL REBUILD
LATE NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
TEMPERATURES ARE JUST NOT RISING AS EXPECTED. ADJUSTED HIGH
TEMPERATURES DOWN ANOTHER 1-2 DEGREES MOST LOCATIONS. MOSTLY
CLOUDY TO CLOUDY CONDITIONS WILL CONTINUE ALTHOUGH THE AREA OF
CLEARING NOTED OVER NORTHERN/CENTRAL GEORGIA COULD APPROACH
WESTERN AREAS LATER THIS AFTERNOON. ADJUSTED SKY GRIDS TO TRY AND
ACCOUNT FOR THIS.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH MONDAY/...
PROGRESSIVE SYSTEM CURRENTLY MOVING INTO THE PLAINS STATES IS
EXPECTED TO EJECT THROUGH THE GULF COAST REGION THIS EVENING AND
QUICKLY RACE INTO GEORGIA AND THE CAROLINAS TONIGHT. THE UPSTREAM
UPPER TROUGH IS ANCHORED BY A 100 KT JET AT 500 MB AND LOOKS TO PACK
A QUICK-HITTING RAINFALL EVENT OVER THE REGION. THE 00Z NAM WAS AN
OUTLIER FOR THIS MODEL RUN...LOOKING MUCH STRONGER THAN OTHER MODELS
WITH FEATURES SUCH AS AN 850 MB JET NEARING 70 KT PROGGED TO RACE
THROUGH SOUTH CAROLINA BY DAYBREAK ON SAT. BLENDING PERSISTENCE WITH
LATEST RUNS OF THE GFS AND ECMWF SUGGEST OUR FORECAST IS ON THE
RIGHT TRACK WITH A GOOD BOUT OF DEEP LAYERED OMEGA/ASCENT SCOOTING
THROUGH THE REGION AFTER MIDNIGHT. THE LOW LEVEL JET LOOKS TO BE
STRONG IN THE 50 KT RANGE AND ENVIRONMENTS IN THE MID LEVELS
CERTAINLY COULD SUPPORT ISOLATED ELEVATED THUNDER BUT TOSSING OUT
THE NAM WOULD SETTLE FOR LEAVING IT OUT OF OUR FORECAST.

WE THINK MODEL DEPICTIONS OF THE LATE NIGHT WARM FRONT ARE PROBABLY
A BIT TOO FAR N. SURFACE WAVES WILL MOVE INTO THE REGION NEARING
DAYBREAK WITH THE BACK EDGE OF THE PRECIP ALSO APPROACHING FROM
THE W QUITE QUICKLY. THE SPEED OF THIS SYSTEM WILL KEEP QPF
AMOUNTS CLOSER TO 1/2 INCH AMOUNTS HOWEVER ANY BANDING OR MORE
CONVECTIVE ELEMENTS MAY DUMP LOCALLY HIGHER TALLIES. GIVEN A
TRICKY LOW LEVEL STABILITY ENVIRONMENT...WE DID NOT ALTER LOW
TEMPS ON THIS PACKAGE.

THE GUIDANCE HAS BEEN TRENDING FASTER WITH THE DYNAMIC FRONTAL
SYSTEM CROSSING THE AREA ON SATURDAY. GLOBAL MODELS ARE IN PRETTY
GOOD AGREEMENT THAT THE FRONT WILL BE PUSHING OFFSHORE BY EARLY
SATURDAY AFTERNOON SO WE ARE SHOWING POPS DROPPING OFF RAPIDLY FROM
WEST TO EAST SATURDAY MORNING. AS THE UPPER TROUGH AXIS SHIFTS EAST
OF THE AREA...COLD DRY ADVECTION AND DOWNSLOPING SHOULD CLEAR THE
CLOUDS OUT PRETTY QUICKLY AFTER THE SHOWER ACTIVITY EXITS. FOR HIGH
TEMPS IT LOOKS LIKE COASTAL AREAS WILL HAVE MORE TIME TO WARM UP
BEFORE THE COLD ADVECTION KICKS IN. INLAND AREAS WILL LIKELY TOP OUT
IN THE UPPER 50S WHILE COASTAL LOCATIONS CLIMB INTO THE LOWER 60S IN
THE EARLY AFTERNOON. WINDS WILL BECOME A LITTLE GUSTY IN THE
AFTERNOON AS MIXING IMPROVES...WITH WEST WINDS OF 10-15 KT GUSTING
TO 20 KT. AT THIS POINT WE HAVE WINDS ON LAKE MOULTRIE REMAINING
JUST BELOW LAKE WIND ADVISORY CRITERIA.

SATURDAY NIGHT LOWS WILL BE ON THE ORDER OF 10-15 DEGREES COLDER
THAN TONIGHT DUE TO FAIRLY STRONG COLD ADVECTION. ABOUT 30 KT OF
NORTHWESTERLY GEOSTROPHIC FLOW WILL EQUATE TO 8-10 KT SURFACE WINDS
OVERNIGHT AND TEMPS WILL DROP BELOW FREEZING INLAND. MIDDLE 30S
EXPECTED ELSEWHERE.

COOL SURFACE HIGH PRESSURE WILL PERSIST ON SUNDAY. THE 850 MB RIDGE
WILL BE BUILDING TO THE EAST DURING THE DAY...MODERATING LOW-LEVEL
THICKNESSES. HOWEVER THIS WARMING OF THE LOW-LEVELS WILL PROBABLY BE
TOO LITTLE TOO LATE TO GET SUNDAY HIGH TEMPS MUCH ABOVE THE LOWER
50S DESPITE SUNNY SKIES.

ANOTHER COLD NIGHT IS IN STORE FOR SUNDAY NIGHT...ALTHOUGH THIS TIME
THE COOLING WILL PRIMARILY BE VIA RADIATION. SOME WISPS OF CIRRUS
MAY BEGIN TO POKE INTO THE AREA LATE BUT WITH THE IN-SITU SURFACE
HIGH DECOUPLING THE BOUNDARY LAYER AND NO LOW/MID CLOUDS THE EARTH
SHOULD RADIATE READILY. FORECAST LOW TEMPS RANGE FROM UPPER 20S
INLAND TO MIDDLE 30S AT THE IMMEDIATE BEACHES.

MONDAY SHOULD CONTINUE THE PRECIP-FREE SPELL BUT DEWPOINTS WILL BE
ON THE REBOUND AS THE DAY WEARS ON. AN INCREASING SOUTHERLY FLOW ON
THE WESTERN PERIPHERY OF THE SURFACE RIDGE WILL RESULT IN WARMER
TEMPS AROUND 60 DEGREES BUT WITH A DECENT SHIELD OF CIRRUS AND SOME
AFTERNOON CUMULUS IN A FEW PLACES.

&&

.LONG TERM /MONDAY NIGHT THROUGH THURSDAY/...
THE UPPER PATTERN WILL FAVOR A QUASI-ZONAL FLOW WITH SEVERAL
PERTURBATIONS RIPPLING THROUGH DURING THE PERIOD. ALTHOUGH MODEL
TIMING DIFFERENCES INEVITABLY ABOUND...A COLD FRONT IS EXPECTED TO
DROP INTO THE REGION FROM THE NW ON TUESDAY AND DRIFT OFFSHORE BY
WEDNESDAY. THEN A SERIES OF WEAK SURFACE WAVES WILL LIFT FROM THE
GULF OF MEXICO THROUGH THE SOUTHEAST WEDNESDAY NIGHT THROUGH
THURSDAY NIGHT. WE GENERALLY HAVE SOLID CHANCE POPS THROUGHOUT THE
PERIOD.

&&

.AVIATION /17Z FRIDAY THROUGH TUESDAY/...
VFR THROUGH THIS EVENING WITH CONDITIONS DETERIORATING EARLY
SATURDAY. WARM FRONT WILL LIFT NORTH THROUGH THE TERMINALS AFTER
MIDNIGHT WITH A 40-50 KT LOW-LEVEL JET INITIATING LOW-LEVEL WIND
SHEAR /LLWS/ AT BOTH TERMINALS AFTER 08-09Z. THE RISK FOR LLWS
WILL LINGER UNTIL FRONTAL PASSAGE ROUGHLY 14-15Z. A WELL DEFINED
RAIN BAND WILL ACCOMPANY THE FRONT WITH RAIN REACHING THE
TERMINALS AS EARLY AS 09Z. LIMITED CIGS/VSBYS TO MVFR FOR NOW
GIVEN THE SPACIAL/TEMPORAL UNKNOWNS THIS FAR OUT...BUT IFR
CONDITIONS ARE CERTAINLY A POSSIBILITY. EXPECT RAPID CLEARING TO
ENSUE ONCE THE FRONT SHIFTS OFFSHORE AND DOWNSLOPE TRAJECTORIES
TAKE HOLD.

EXTENDED AVIATION OUTLOOK...INCREASING CHANCES FOR SUB-VFR
CONDITIONS TUESDAY AND TUESDAY NIGHT AS A COLD FRONT MOVES IN.

&&

.MARINE...
WINDS LIGHT AND PERIODICALLY VARIABLE TODAY AS A WEAK BOUNDARY AND
PRES PATTERN SAG OVER THE WATERS. SEAS 1 TO 2 FT. THE COASTAL
WATERS FORECAST RAPIDLY GOES FROM MUNDANE TO COMPLEX TONIGHT AS A
POTENT 40-50 KT LOW LEVEL JET RACES OVER A RELATIVELY STABLE
MARINE ENVIRONMENT ESPECIALLY WITH DEVELOPING RAINFALL AND STRONG
WARM AIR ADVECTION JUST ABOVE THE BOUNDARY LAYER. WE HAVE LOW
CONFIDENCE ON MIXING PROFILES BUT SUSPECT ANY RISK FOR BORDERLINE
SMALL CRAFT ADVISORY CONDITIONS WOULD OCCUR LATE TONIGHT OVER OUR
GEORGIA WATERS WELL BEYOND 20 NM OFFSHORE. WE CONTINUED FORECAST
TRENDS FOR VEERING FLOW TO A MORE S OR SSW COMPONENT LATE BUT
PLAYED WIND SPEEDS CONSERVATIVELY AT THIS POINT. SEA HEIGHTS WILL
BUILD LATER TONIGHT BUT LIKELY NO HIGHER THAN 4 TO 5 FT WELL OFF
THE GEORGIA COAST PRIOR TO 12Z SAT.

SMALL CRAFT ADVISORIES WILL EVENTUALLY BE NEEDED SATURDAY AND
SATURDAY NIGHT FOR ALL WATERS EXCEPT THE CHARLESTON HARBOR AS COLD
ADVECTION AND LOW-LEVEL JETTING IMPACT THE MARINE AREA. SCA
CONDITIONS WILL PROBABLY PERSIST INTO SUNDAY MORNING FOR THE
OFFSHORE GA WATERS WHERE THE WARMER WATERS WILL ENABLE DEEPER
MIXING. BEYOND SUNDAY WE ANTICIPATE FAIRLY QUIET CONDITIONS WITH
HIGH PRESSURE IN CONTROL.
