Flash Flood Warning 57, NWS Greenville-Spartanburg, SC

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
759 AM EST WED DEC 30 2015

.SYNOPSIS...
MOISTURE WILL PERSIST THROUGH THURSDAY AS A FRONT REMAINS STALLED IN
THE AREA. A DRYING TREND WILL BEGIN ON NEW YEARS...LASTING AT LEAST
INTO EARLY NEXT WEEK...AS HIGH PRESSURE PUSHES IN FROM THE WEST.

&&

.NEAR TERM /THROUGH TONIGHT/...
1300 UTC UPDATE...QPF HAVE BEEN RAISED OVER NE GA AND UPSTATE SC
PER TRENDS UPSTREAM IN N GA.

AS OF 630 AM EST WEDNESDAY...AS UPPER SUPPORT RAMPS UP AHEAD OF
AN APPROACHING JETMAX...STARTING TO SEE INCREASING SHRA COVERAGE
ACROSS THE AREA.  THE FRONTAL AXIS TO THE SOUTH IN SLOWLY ON THE
MOVE AS EXPECTED WITH NEARLY ALL SITES SOUTH OF I85 REPORTING IN
WITH SOUTHERLY FLOW AND IMPROVING DEWPOINTS.  OTHERWISE...TWEAKED
POPS A BIT TO ALIGN WITH CURRENT RADAR COVERAGE...ALONG WITH MINOR
ADJUSTMENTS TO TEMPERATURES/DEWPOINTS TO REFLECT OBS.  NO OTHER
CHANGES NEEDED/MADE WITH THIS UPDATE.

PREVIOUS DISCUSSION...THE COMBINATION OF H5 RIDGING OVER THE
WESTERN ATLANTIC AND BROAD TROFING OVER THE CENTRAL CONUS CONTINUES
TO YIELD DEEP SOUTHWEST FLOW ALOFT ACROSS THE SOUTHEAST STATES.
AT THE SURFACE...THE OLD STATIONARY COLD FRONTAL AXIS IS STARTING
ITS PROGGED NORTHWARD MIGRATION AS A WARM FRONT THIS MORNING.
ADDITIONALLY...AN APPROACHING UPPER LEVEL JET MAX EJECTING
THROUGH THE SOUTHERN PLAINS AROUND THE BASE OF THE PARENT TROF
WILL AID UPPER DIVERGENCE WHILE A SERIES OF H5 VORT LOBES SLIDE
ALONG THE MEAN FLOW IN PROXIMITY TO THE SFC WARM FRONT. GIVEN THE
A FORE MENTIONED FEATURES... ALONG WITH THE MEANDERING FRONTAL
AXIS...AND AMPLE MOISTURE BY WAY OF PWAT VALUES IN EXCESS OF 3-4
STD DEVS ABOVE NORMS...MODERATE TO HEAVY RAINFALL LOOKS PROBABLE.
THE FCST CHALLENGE IS DETERMINING THE PLACEMENT OF SUCH. MOST RECENT
GUIDANCE HAS TRENDED A QPF MAXIMA OUTSIDE OF THE NC MTNS AND ACROSS
NE GA...UPSTATE SC...AND THE ENTIRE NC PIEDMONT...WHICH ALL SEEMS
LOGICAL GIVEN THE QUASISTATIONARY NATURE OF THE FRONT. FOCUSING IN
A LITTLE MORE...THE FCST WILL FAVOR THE I85/I77 CORRIDORS WITH THE
HEAVIEST QPF TOTALS AS SOUNDINGS ARE FAVORABLE FOR MODEST SBCAPE
FOR THIS TIME OF YEAR...UPWARDS OF 500-700 JOULES AS LAPSE RATES
REMAIN RELATIVELY STEEP THROUGH A DEEP LAYER. THUS...THINK DEEPER
CONVECTION COULD YIELD PRECIP RATES IN EXCESS OF A HALF TO ONE
INCH PER HOUR AT TIMES...WITH SOME CELL TRAINING POSSIBLE ALONG
THE FRONT GIVEN FAIRLY UNIDIRECTIONAL FLOW ALOFT. NEW STORM TOTAL
QPF AMOUNTS OF 1-2 INCHES ARE FCST WITH LOCALLY HIGHER AMOUNTS
CERTAINLY BEING A POSSIBILITY.  ALL SAID...WILL OPT TO EXPAND
CURRENT FLOOD WATCH NORTHWEST ACROSS THE I40 CORRIDOR TO CONSUME
THE ENTIRETY OF THE NC PIEDMONT.  LIKEWISE...WILL DROP THE WATCH
FURTHER WEST ACROSS MUCH OF THE NC MTNS.

ADDITIONALLY...AS NOTED ABOVE THERMAL PROFILES THIS AFTERNOON
WILL EXHIBIT MODEST LAPSE RATES WITH GUIDANCE FAVORING A TIGHT
INSTABILITY GRADIENT ADJACENT/SOUTH OF THE WARM FRONT.  DEPENDING OF
THE LOCATION OF THE FRONT...LOCALES IN ITS VICINITY AND SOUTH WILL
SEE INCREASED THUNDER POTENTIAL.  AS FOR SEVERE...DEFINITELY NOT
GOING TO RULE ANYTHING OUT AS THE FRONT WILL PROVIDE ADDED FOCUS
FOR LOCALIZED SHEAR MAXIMAS WITH PROFILES SUPPORTING BULK SHEAR IS
IN THE 40-50KT RANGE ON A BROADER SCALE.  THUS THE HWO WILL INCLUDE
SEVERE WORDING WITH DAMAGING WINDS...FREQUENT LIGHTNING...AND FLASH
FLOODING BEING THE PRIMARY THREATS.  ISOLATED TORNADOES CANNOT BE
RULED OUT GIVEN THE ABUNDANT SHEARING...HOWEVER SLIGHTLY VEERED
SURFACE FLOW WILL LIMIT THE CHANCES SOMEWHAT.  THAT SAID...ANYTIME
THERE COULD BE ENHANCEMENT GIVEN BOUNDARY INTERACTION...ANYTHING
IS POSSIBLE WITH EVEN MODEST INSTABILITY THIS TIME OF YEAR.

AS FOR THE FCST...POPS WILL RAMP UP THIS MORNING FROM THE SOUTH
WITH CAT POPS FAVORED BY MIDDAY ACROSS THE ENTIRE FCST DOMAIN.
POPS WILL REMAIN ELEVATED THROUGH THE AFTERNOON BEFORE GRADUALLY
FALLING OFF FROM THE WEST AFTER SUNSET...INTO THE OVERNIGHT AS
DRIER AIR ADVECTS IN WITH AN INTRUDING COLD FRONT.  TEMPERATURES
WILL BE A TOUCH COOLER THAN DAYS PAST AS ABUNDANT CLOUDINESS
INHIBITS INSOLATION...HOWEVER MAX VALUES NEAR 15 DEGREES ABOVE
CLIMO ARE FCST.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
AS OF 230 AM WEDNESDAY...SOUTHWEST FLOW ALOFT WILL CONTINUE OVER
THE SOUTHEAST AND SOUTHERN APPALACHIANS AT THE START OF THE SHORT
TERM...WITH THE COLD FRONT STALLED ACROSS SOUTHEASTERN PORTIONS OF
THE FORECAST AREA. STRONG SHORTWAVE DIGGING OUT OF SOUTH CENTRAL
CANADA INTO THE NORTHERN PLAINS WILL USHER IN THE PATTERN CHANGE
FOR THE WEEKEND. 00Z GUIDANCE IS SLOW TO MOVE THE PRECIP OUT OF OUR
SOUTHEAST ZONES THURSDAY...SO HAVE HUNG ONTO SLIGHT CHANCE SHOWERS
ACCORDINGLY. SURFACE HIGH PRESSURE BUILDS IN FROM THE WEST AND
FINALLY PUSHES ALL THE PRECIP OUT LATE ON FRIDAY. THE AFOREMENTIONED
SHORTWAVE CONTINUES TO DIG SOUTHEAST...WITH THE TROUGH AXIS CROSSING
THE SPINE OF THE APPALACHIANS TOWARD THE END OF THE PERIOD. GFS IS
A LITTLE FASTER WITH THIS...WITH THE TROUGH AXIS PUSHING THROUGH
BY 06Z SATURDAY...BUT THE ECMWF IS A TAD SLOWER AND HAS THE TROUGH
AXIS RIGHT ON THE TN/NC LINE AT THE END OF THE SHORT TERM.

THE BIG STORY WILL BE THE CHANGE IN TEMPERATURES IN THE WAKE
OF THE COLD FRONT...WITH A SECONDARY COOL-DOWN BEHIND THE
LATE-PERIOD TROUGH AXIS WHICH WILL BE REALIZED AS WE BEGIN THE
EXTENDED. SHOULD STILL SEE HIGHS WELL ABOVE SEASONAL NORMALS FOR
THE FOOTHILLS AND PIEDMONT ON THURSDAY /DEPENDING ON EXACTLY WHERE
THE FRONT IS LOCATED AT MAX HEATING/...BUT THE MOUNTAINS WILL
ALREADY BE EXPERIENCING SOME RELIEF FROM THE SPRING-LIKE TEMPS BY
THURSDAY. HIGHS THURSDAY SHOULD BE 5 OR SO DEGREES COOLER THAN
THOSE TODAY. FOR NEW YEARS DAY HOWEVER...WITH THE CAA PUSHING
IN...SHOULD SEE ANOTHER 10 DEGREE DROP IN HIGHS TO JUST SLIGHTLY
ABOVE SEASONAL AVERAGES. THE AREA HASN'T SEEN TEMPERATURES BELOW
FREEZING SINCE DECEMBER 20 AND BY NEW YEARS NIGHT...THE MOUNTAINS
AND FOOTHILLS WILL BE BACK INTO THE SWING OF NORMAL WINTER.

OTHER THAN THE TEMPERATURES...CANNOT TOTALLY RULE OUT SOME
ISOLATED SNOW SHOWERS AT THE HIGHEST ELEVATIONS LATE THURSDAY/EARLY
FRIDAY...BUT SYNOPTIC SETUP NOT PARTICULARLY SUPPORTIVE SINCE IT
IS MORE WEST TO SOUTHWEST FLOW ALOFT. TEMPS WILL BE JUST ABOVE
FREEZING FOR THE MOST PART THURSDAY NIGHT SO CONFIDENCE JUST NOT
ENOUGH TO INCLUDE ANY FLURRIES/SNOW SHOWERS AT THIS TIME.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
AS OF 245 AM WEDNESDAY...WE START THE EXTENDED EITHER RIGHT AFTER
THE SECONDARY UPPER TROUGH AXIS AND DRY COLD FRONT /ON THE GFS/
OR WITH IT RIGHT ON OUR DOORSTEP /ECMWF/...BUT THE RESULTING
SENSIBLE WEATHER IS THE SAME. CAA BEHIND THE SYSTEM WILL RESULT
IN HIGHS SATURDAY ACTUALLY BELOW...YES BELOW...SEASONAL NORMALS
FOR THE AREA. THIS IS SHORT-LIVED AS WE WARM UP AGAIN SUNDAY WITH
WEAK CONFLUENT FLOW ALOFT...AND RIDGING BUILDING INTO THE CENTER OF
THE COUNTRY. DRY HIGH PRESSURE WILL DOMINATE OUR WEATHER...THOUGH
UNSETTLED WEATHER IS JUST A STATE AWAY IN SOUTH GEORGIA AND ALONG
THE FLORIDA PANHANDLE AS THE FRONT REMAINS STALLED IN THOSE AREAS.

MODELS DIVERGE PRETTY SIGNIFICANTLY EARLY NEXT WEEK WITH THE GFS
BRINGING ANOTHER SHORTWAVE THROUGH EARLY MONDAY BUT WITH WEAK
RIDGING BUILDING IN FOR THE ECWMF. HOWEVER...DRY WEATHER SHOULD
CONTINUE TO DOMINATE...ALLOWING THE FORECAST AREA TO CONTINUE
TO DRY OUT...THOUGH THERE MAY BE SOME QUESTION AS TO ACTUAL
TEMPERATURES. FOR NOW HAVE KEPT A BLEND WITH TEMPERATURES PRETTY
CLOSE TO SEASONAL NORMALS. MIGHT START SEEING SOME PRECIPITATION
CREEP BACK INTO THE AREA AT THE VERY END OF THE PERIOD BUT NOT
ENOUGH CONFIDENCE TO INCLUDE AT THIS TIME.

&&

.AVIATION /13Z WEDNESDAY THROUGH SUNDAY/...
AT KCLT...IFR THROUGH MID/LATE MORNING BEFORE SOME SLIGHT
IMPROVEMENT TO MVFR AS MIXING IMPROVES. AS THE WARM FRONT SHIFTS
NORTH...DEEPER MOISTURE AND INCREASING INSTABILITY WILL BE FAVORED
THUS TAF CONTINUES TO FEATURE TSRA BY WAY OF PROB30S THIS AFTERNOON.
IT IS POSSIBLE THAT THUNDER COULD OCCUR SOONER...THUS LATER
ADJUSTMENTS TO INCLUDE TEMPOS ARE PROBABLE.  ALL WX IS REMOVED
NLT THAN 06Z WITH CIGS LINGERING AT IFR/LIFR THROUGH PERIODS END.
WINDS WILL REMAIN SOUTHERLY THROUGH THIS TAF CYCLE WITH SOME
GUSTING POSSIBLE THIS AFTERNOON.

ELSEWHERE...MUCH THE SAME AS KCLT ABOVE FOR THE SC SITES AND
KAVL AS MOISTURE INCREASES YIELDING LOWERED CIGS/VISB WITH
SHRA SPREADING OVER THE AREA.  EXPECTING MVFR INITIALLY WITH
IFR CIGS/VISB BY MID/LATE MORNING FOR THESE LOCALES WITH SHRA
INCREASING IN COVERAGE.  CIGS ARE THEN FCST TO IMPROVE YET AGAIN TO
MVFR WITH SOME LINGERING SCT IFR STRATUS THIS AFTN...WITH THE TAF
CONTINUING TO HIGHLIGHT TSRA POTENTIAL THIS AFTN BY WAY OF VCTS
MENTION.  AS FOR KHKY...CONDITIONS WILL CONTINUE TO DETERIORATE
WITH TIME...HOWEVER DELAYED GIVEN PROXIMITY TO ENCROACHING DEEPER
MOISTURE AXIS AND ANY UPSTREAM SHRA.  LIKEWISE...TSRA POTENTIAL
WILL ALSO BE LESS AT KHKY THEREFORE NOT INCLUDED IN THIS TAF SET.
WINDS AT ALL SITES WILL REMAIN LIGHT/MODERATE AND SOUTHERLY THROUGH
THE PERIOD EXCEPT FOR AT KAVL WHERE A COLD FRONT WILL PASS LEADING
TO VEERED NW FLOW LATE IN THE TAF CYCLE.

OUTLOOK...DEEP LAYER MOISTURE WILL DECREASE ON THURSDAY AS A COLD
FRONT SWEEPS THROUGH THE AREA ALLOWING FOR THE RETURN OF COOL/DRY
HIGH PRESSURE AND THUS LOW CHANCES FOR RESTRICTIONS THROUGH THE
WEEKEND.

.HYDROLOGY...
SOME CHANGES TO FLOOD WATCH PLACEMENT WITH THIS FCST.  LOCALES
ACROSS NE GA AND UPSTATE SC REMAIN UNCHANGED WHILE THE WATCH WAS
EXPANDED NW TO INCLUDE THE ENTIRE NC PIEDMONT AS LATEST GUIDANCE
FAVORS A SHIFTED QPF MAXIMA ALONG THE QUASISTATIONARY FRONTAL AXIS.
FURTHERMORE...MUCH OF THE WESTERN EXTENT OF THE PREVIOUS WATCH
WAS REMOVED AS SAID MAXIMA REMAINS OUTSIDE OF THE MTNS.

STREAM LEVELS AROUND THE REGION ARE RUNNING QUITE HIGH GIVEN THE
RECENT RAINFALL. ALTHOUGH ADDITIONAL QPF GOING FORWARD MAY BE
LIMITED TO 1 TO 2 INCHES IN MANY AREAS...WET ANTECEDENT CONDITIONS
ALONG WITH POSSIBLY HIGHER RATES IN CONVECTION THIS AFTERNOON WILL
YIELD A RENEWED FLOODING THREAT.

DEEP MOISTURE WILL RETURN OVER THE STALLED FRONTAL BOUNDARY
TONIGHT...BRINGING PRECIPITABLE WATER ANOMALIES OF 2 TO 3+ STANDARD
DEVIATIONS ABOVE NORMAL TO THE REGION. THIS WILL INTERACT WITH MANY
AREAS WHERE 3 HOUR FLOOD GUIDANCE IS GENERALLY LESS THAN 2 INCHES.
