Area forecast discussion, Jan 11, 6:54 AM EST, 3 hours 30 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
654 AM EST SAT JAN 11 2014

.SYNOPSIS...
A COLD FRONT WILL CROSS OUR REGION FROM THE WEST TODAY AND BE WELL
OFF THE CAROLINA COAST BY SUNDAY MORNING.  DRY HIGH PRESSURE WILL BE
IN CONTROL OF OUR WEATHER SUNDAY AND EARLY MONDAY.  SHOWERS WILL
RETURN MONDAY EVENING INTO TUESDAY MORNING AS A WEAK COLD FRONT
PASSES THROUGH.

&&

.NEAR TERM /THROUGH TONIGHT/...
AS OF 630 AM EST...THE LEAD AREA OF CONVECTION MOVING NWD OVER THE
SHALLOWING CAD LAYER HAS PRODUCED LOCAL ONE HALF TO THREE QUARTER
INCH PER HOUR RAINFALL RATES...AND ASSOCIATED MINOR FLOODING. THIS
REGION OF HEAVIER PRECIP WILL CONTINUE TO MOVE NE OVER THE NC
PIEDMONT THROUGH 8 AM. MEANWHILE...RADARS TO THE WEST ARE SHOWING
LINES OF HEAVY PRECIP AHEAD OF THE SFC FRONT MOVING RAPIDLY EWD
THROUGH TN. THIS SHOULD ALLOW THE HEAVY RAINFALL TO REFOCUS A BIT
BACK OVER THE SW MTNS IN UPSLOPE FLOW AND IMPROVING UPPER SUPPORT.
MEANWHILE...THE 850 MB JET HAS INCREASED TO 50 TO 60 KT AND AS
INDICATED ON VAD WIND PROFILES. WINDY CONDITIONS WILL THUS CONTINUE
OVER THE RIDGE TOPS THIS MORNING...WITH THE BEST SHEAR PROFILES
WORKING EAST THROUGH THE DAY. AS THE SHALLOW COLD WEDGE LAYER EAST
OF THE MTNS GETS PINCHED AND ERODES IN INCREASING SOUTHERLY BL
FLOW...ENOUGH OVERLAP OF SHEAR AND CAPE IN SRN/ERN SECTIONS WILL
OCCUR TO SUPPORT AN ISOLD SEVERE WEATHER THREAT. THIS IS MENTIONED
IN THE HWO IN LINE WITH THE SPC SLIGHT RISK AREA. SHERB VALUES
CONTINUE TO SHOW 1+ ALONG AND EAST OF INTERSTATE 77 BY 18Z.

THE COLD FRONT SHOULD MOVE EAST OF THE AREA 21Z TO 00Z JUST AS THE
DEEPER DPVA WITH THE UPPER WAVE SWINGS THROUGH ALONG WITH DRYING.
LAPSE RATES UNDER THE PASSING TROUGH ARE QUITE STEEP TONIGHT...BUT
PROFILES APPEAR TOO DRY FOR PRECIPITATION IN THE COLD ADVECTION
EXCEPT IN THE NC MOUNTAINS WHERE BRIEF NW FLOW MOISTURE WILL OCCUR.
ACCUMULATIONS LESS THAN AN INCH WILL BE POSSIBLE ALONG THE HIGHER
TERRAIN IN THE COLD ADVECTION TONIGHT.

&&

.SHORT TERM /SUNDAY THROUGH TUESDAY/...
AT 230 AM EST SATURDAY...MODELS REMAIN IN GOOD AGREEMENT WITH REGARD
TO OVERALL SYNOPTIC PATTERN AS THE SHORT TERM PERIOD INITIALIZES
SUNDAY MORNING.  DEEP UPPER TROF MOVING THROUGH THE REGION TODAY
WILL BE PUSHING OFFSHORE ALLOWING FOR HEIGHTS TO RISE ACROSS THE
SOUTHEAST.  DEEP LAYER RIDGING WILL STRENGTHEN AND SHIFT EASTWARD
ACROSS THE SOUTHERN APPALACHIANS DURING THE DAY ON SUNDAY ALLOWING
FOR SUNNY SKIES TO PREVAIL.  WINDS WILL SHIFT SOUTHWESTERLY THROUGH
THE DAY AS THE SURFACE RIDGE MIGRATES EASTWARD WHICH WILL SETUP WARM
RETURN FLOW FROM THE EASTERN GULF.  TEMPERATURES ON SUNDAY AND
MONDAY WILL BE GENERALLY ABOVE NORMAL FOR BOTH DAYTIME HIGHS AND
OVERNIGHT LOWS MONDAY MORNING.

MEANWHILE...ANOTHER UPPER LONGWAVE TROF WILL BE DIGGING OUT ACROSS
THE SOUTHERN PLAINS WHILE WARM ADVECTION RAMPS UP ACROSS THE
SOUTHEAST THROUGH THE DAY MONDAY.  A WEAK COLD FRONT WILL PUSH INTO
THE SOUTHERN APPALACHIANS MONDAY NIGHT WITH SHOWERS SPREADING ACROSS
THE AREA.  IN RESPONSE...POPS WILL INCREASE TO LIKELY LEVELS LATE IN
THE DAY MONDAY THROUGH THE OVERNIGHT HOURS OF TUESDAY MORNING BEFORE
DECREASING THROUGH LATE MORNING HOURS AS THE BOUNDARY PUSHES EAST.
BACK TO THE WEST ALONG THE HIGH TERRAIN...A FEW SNOW SHOWERS COULD
INITIATE AMONGST WEAK WESTERLY UPSLOPE FLOW AS LOW LEVEL MOISTURE
POOLS ALONG THE WESTWARD FACING SLOPES.  THEREFORE KEPT PREVIOUS
FORECAST MENTION OF CHANCES FOR SNOW SHOWERS WITH ACCUMULATIONS
REMAINING GENERALLY LESS THAN AN INCH ALONG THE HIGHER RIDGE TOPS.
CONFIDENCE IN THIS BRIEF UPSLOPE EVENT IS NOT ENTIRELY HIGH AS
MODELS SEEMS TO BE IN DISAGREEMENT WITH REGARDS TO THERMAL
PROFILES.  NAM/GFS HAVE COOLER SOLUTIONS WHILE THE ECMWF IS THE
WARMER OF THE THREE...THEREFORE LIMITED POPS TO LOW END CHANCE
LEVELS.  TEMPERATURES ON TUESDAY WILL NOT SUFFER IN THE WAKE OF THE
WEAK FROPA AS NEAR NORMAL HIGHS WILL PREVAIL.

&&

.LONG TERM /TUESDAY NIGHT THROUGH FRIDAY/...
AS OF 215 AM SAT...THE MEDIUM RANGE MODELS HAVE DIFFERENCES IN
TIMING OF SYSTEMS. AT 00Z WED...THEY ARE IN FAIRLY GOOD AGREEMENT
BUT THEN DIFFER QUITE A LOT LATER IN THE WEEK. A STRONG SHORTWAVE
WILL DROP DOWN FROM THE OHIO AND TENNESSEE VALLEYS TUESDAY EVENING
REACHING THE NC MTNS BY 06Z WED. THICKNESSES PLUG RAPIDLY LATE
TUESDAY NIGHT WITH THE AXIS OF THE TROUGH REACHING OUR AREA WED
MORNING. PRESSURE GRADIENT GREATEST IN THE 12Z TO 18Z TIME WHICH
WILL LEAD TO THE GREATER WIND SPEEDS. LOW LEVEL WIND WILL BE
WESTERLY AT 00Z AHEAD OF THE SHORTWAVE AND THEN SWITCH TO NW AT
SPEEDS OF 15 TO 25KTS AT 850MB THROUGH WED MORNING. CONTINUED NW
INTO WED EVENING BUT 10 TO 20KT WIND AT 850MB. THE STRENGTH OF THE
SHORTWAVE WILL CONTRIBUTE TO SOME LIGHT PRECIP MAKING ITS WAY ACROSS
THE NC FOOTHILLS AND PIEDMONT...BUT WILL BE LIMITED DUE TO
DOWNSLOPE. SNOW RATES ARE GREATEST WED MORNING AND THEN TAPER OFF
AND END WED EVENING.

HIGH PRESSURE BUILDS IN FROM THE WEST WED NIGHT THROUGH THURSDAY
NIGHT. THERE IS ANOTHER STRONG SHORTWAVE REACHING OUR REGION ON
FRIDAY BUT MOISTURE SEEMS QUITE LIMITED. THE GFS IS MUCH MORE
PROGRESSIVE WITH THIS SHORTWAVE AS IT REACHES THE NC MTNS 12Z FRIDAY
WITH AXIS OVER OUR AREA AT 18Z FRIDAY THEN MOVING IT OFF THE EAST
COAST FRIDAY EVENING. THE ECMWF HAS IT REACHING THE NC MTNS AT 18Z
FRIDAY WITH AXIS OF TROUGH GETTING TO US AT 18Z SATURDAY.

TEMPERATURES WILL BE 5 TO 10 DEGREES BELOW NORMAL THROUGH THE MEDIUM
RANGE PERIOD.

&&

.AVIATION /12Z SATURDAY THROUGH WEDNESDAY/...
AT KCLT...LLWS WILL PERSIST THROUGH THE MORNING HOURS AS A STOUT 50
TO 60 KT 850 MB JET MOVES IN ATOP A SHALLOWING COLD WEDGE BOUNDARY
LAYER. WILL NEED TEMPO THUNDER FOR A COUPLE HOURS THIS
MORNING...THEN A RETURN TO CATEGORICAL THUNDER AFTER 17Z WITH THE
MAIN PRE/FRONTAL BAND. CONDITIONS MAY VARY AT TIMES...BUT EXPECT
MOSTLY IFR TO LIFR CONDITIONS UNTIL FROPA. SRLY WINDS WILL BECOME
INCREASINGLY GUSTY THROUGH 21Z AND THEN SHIFT SHARPLY WEST THEN NW
WITH FROPA.

ELSEWHERE...TEMPO MORNING TSTMS WILL GIVE WAY TO BRIEFLY WEAKER
SHOWERS AND THEN ANOTHER ROUND OF FRONTAL TSTMS THROUGH MIDDAY.
EXPECT MAINLY LIFR TO IFR CONDITIONS THROUGHOUT. WILL CONTINUE THE
LLWS MENTION THROUGH THE MORNING AT MOST SITES GIVEN THE STOUT SRLY
JET JUST ABOVE THE COOL STABLE SFC LAYER. SRLY FLOW WILL INCREASE
UNTIL FROPA 17Z TO 20Z...WITH A SHARP SHIFT TO W THEN NW THIS AFTN.
EXPECT CLEARING EAST OF THE MTNS THROUGH TONIGHT...WITH LINGERING NW
FLOW MOISTURE FLIRTING WITH KAVL.

OUTLOOK...DRY HIGH PRES WILL RETURN SUNDAY INTO MONDAY. SWIFTLY
MOVING LOW PRESSURE SYSTEMS MAY THEN BRING UNSETTLED CONDITIONS BACK
INTO THE REGION FROM THE WEST TUE INTO WED.
