AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RALEIGH NC
305 PM EDT SAT AUG 18 2012

.SYNOPSIS...
A WEAK COLD FRONT WILL STALL OVER EASTERN NORTH CAROLINA TONIGHT
AND SUNDAY.  AN AREA OF LOW PRESSURE WILL APPROACH FROM THE
SOUTHWEST LATE SUNDAY AND SUNDAY NIGHT.

&&

.NEAR TERM /THROUGH TONIGHT/...
AS OF 305 PM SATURDAY...

TONIGHT...SURFACE BOUNDARY DRIFTING SEWD ACROSS THE FORECAST AREA AT
2 PM. CONFLUENCE WEAK AT THIS TIME THOUGH APPROACH OF A MODEST
CONVECTIVELY INDUCED VORT MAX (CURRENTLY CROSSING UPSTATE SC) MAY
LEAD TO SOME LOW LEVEL ENHANCEMENT OVER THE SOUTHERN  PIEDMONT AND
SANDHILLS...LEADING TO SCATTERED CONVECTION THROUGH 7 PM. EXPECT
BEST COVERAGE TO OCCUR SE OF A LINE FROM ROCKINGHAM TO WILSON. NOT
TOO OVERLY CONCERNED ABOUT PROBABILITY OF SEVERE STORMS AT THIS TIME
THOUGH EFFECTIVE BULK SHEAR OF 40KTS OVER THE SOUTHERN COUNTIES (PER
SPC MESO-ANALYSIS) SUGGEST LIKELIHOOD OF ORGANIZED BROKEN BANDS OF
CONVECTION WITH STRONG...LOCALLY DAMAGING WINDS...POSSIBLE IN THE
STRONGER CELLS. OTHER CONVECTIVE PARAMETERS SUGGEST WEAK
PROBABILITIES FOR LARGE HAIL AND FREQUENT/EXCESSIVE LIGHTNING.

EXPECT BULK OF CONVECTIVE ACTIVITY TO DIMINISH/DISSIPATE WITHIN AN
HOUR OR TWO OF SUNSET WHILE SURFACE FRONT PREDICTED TO STALL TO
SOUTH OF OUR AREA LATE TONIGHT. MIN TEMPS 65 TO 70.

&&

.SHORT TERM /SUNDAY THROUGH TUESDAY NIGHT/...
AS OF 300 AM EDT SATURDAY...

SUNDAY AND SUNDAY NIGHT....A DEEPENING MID-UPPER LEVEL TROUGH
EXTENDING FROM THE GREAT LAKES SWD INTO THE TN VALLEY WILL BACK THE
MID-UPPER LEVEL FLOW OVER CENTRAL NC. THIS SW FLOW WILL TAP TROPICAL
MOISTURE AND ADVECT IT INTO CENTRAL NC. THE DEEP MOIST AIR MASS
COUPLED WITH A SERIES OF PERTURBATIONS IN THE SW FLOW ALOFT WILL
CAUSE EPISODES OF SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS
SUNDAY INTO EARLY MONDAY. SHORT RANGE MODEL GUIDANCE IN AVERAGE
AGREEMENT IN DEPICTING A MID LEVEL TROUGH APPROACHING/LIFTING ACROSS
CENTRAL NC SUNDAY AFTERNOON-EARLY EVENING. STALLED SURFACE BOUNDARY
PROJECTED TO WAVER BACK TO THE NW SUNDAY AS SURFACE LOW LIFTS NEWD
ALONG THE BOUNDARY. THIS SURFACE LOW MAY AID TO ENHANCE LOW LEVEL
HELICITY IN VICINITY OF THE FRONT (12Z GFS SUGGEST 150-180 M2/S2 IN
THE COASTAL PLAIN LATE SUNDAY)...LEADING TO STRONGER/BETTER
ORGANIZED UPDRAFTS AND A SLIGHTLY HEIGHTENED THREAT FOR SEVERE
STORMS WITH DAMAGING WINDS AND LARGE HAIL THE PRIMARY THREAT THOUGH
A NON-ZERO THREAT FOR TORNADIC STORMS WILL EXIST. PRIMARY DETERRENT
TO CONVECTIVE DEVELOPMENT WILL BE LACK OF LOW LEVEL
INSTABILITY...ESPECIALLY IF CLOUD COVERAGE EXTENSIVE AND THICK
ENOUGH TO LIMIT INSOLATION.

AS THIS MID LEVEL TROUGH EXITS THE REGION EARLY SUNDAY
EVENING...EXPECT A TEMPORARY LULL IN CONVECTIVE ACTIVITY. BOTH 00Z
ECMWF AND 12Z GFS HINT AT THE APPROACH OF ANOTHER MID LEVEL TROUGH
FROM THE SW LATE SUNDAY NIGHT WHICH SUGGEST POTENTIAL FOR SCATTERED
SHOWERS OVERSPREADING THE REGION FROM THE SW AFTER MIDNIGHT.

TEMPS SUNDAY DEPENDENT UPON THICKNESS OF CLOUD COVERAGE. SOLID
OVERCAST WILL LEAD TO MAX TEMPS 3-4 DEGREES COOLER THAN CURRENTLY
FORECAST. BASED ON EXPECTATIONS OF PARTIAL BREAKS AND CONVECTION
HOLDING OFF UNTIL EARLY-MID AFTERNOON...EXPECT MAX TEMPS NEAR 80 NW
TO THE MID 80S EAST. MIN TEMPS SUNDAY NIGHT IN THE MID-UPPER 60S.
-WSS

MONDAY THROUGH TUESDAY NIGHT:
S/W ENERGY CURRENTLY ACROSS THE CENTRAL AND NORTHERN PLAINS IS
DIVING SOUTH/SOUTHEASTWARD DOWN THE BACKSIDE OF THE EASTERN U.S.
TROUGH. THIS WILL HELP TO DEEPEN THE TROUGH ALOFT AND INCREASE
SOUTH/SOUTHWESTERLY FLOW ALOFT ACROSS OUR AREA FOR MONDAY AND
TUESDAY... WITH THE RIGHT ENTRANCE REGION OF THE ASSOCIATED UPPER
JET PROVIDING LARGE SCALE ASCENT ACROSS OUR AREA. HAVE TRENDED THIS
PART OF THE FORECAST TOWARDS A BLEND OF THE 12Z GFS/00Z ECMWF...
WHICH IS SIMILAR TO THE 00Z ECENS MEAN AND CLUSTERED NEAR MIDDLE OF
THE MODEL GUIDANCE WRT THE STRENGTH AND TIMING OF THE H5 TROUGH.
HOWEVER... FINER DETAILS SUCH AS PLACEMENT OF THE FRONT AND TIMING
OF INDIVIDUAL S/W ENERGY AND ASSOCIATED SURFACES WAVES REMAINS IN
QUESTION... AS TO BE EXPECTED 3-4 DAYS OUT. EXPECT THE SURFACE FRONT
DURING THIS TIMEFRAME TO BE GENERALLY LOCATED ACROSS THE EASTERN
HALF OF THE AREA... WAVERING FROM TIME TO TIME AS SURFACE WAVES
TRACK ALONG IT. AS IT APPEARS NOW... THE BEST CHANCE FOR SHOWERS AND
STORMS DURING THIS TIME FRAME WILL BE ON MONDAY... WITH ANOTHER GOOD
CHANCE TUESDAY AFTERNOON. THUS... WILL GO WITH HIGH CHANCE POPS NW
TO LIKELY POPS SE/E. MODELS SHOW A DOWNWARD TREND IN POPS FOR THE
MONDAY NIGHT PERIOD AS THE SURFACE WAVE ASSOCIATED WITH MONDAYS
DISTURANCES LIFTS OFF TO THE NORTHEAST... ALONG WITH NOCTURNAL
STABILIZATION. HOWEVER... WITH PW'S NEAR 2 INCHES ACROSS THE EAST
AND STILL A DEEP SOUTH/SOUTHWESTERLY FLOW ACROSS THE REGION WILL
CONTINUE TO HOLD ONTO CHANCE POPS ACROSS MOST OF THE CWA FOR MONDAY
NIGHT. FOR TUESDAY... UNCERTAINTY CONTINUES WITH REGARD TO S/W
IMPULSES TRACKING ACROSS THE AREA... COUPLED WITH THE L/W TROUGH
BEGINNING TO WEAKEN SOME. FOR NOW WILL GO WITH SLIGHT CHANCE POPS
FAR NW TO SOLID/HIGH CHANCE POPS EAST/SOUTHEAST. HIGH TEMPS BOTH
DAYS WILL BE TRICKY AS WELL. FOR NOW HAVE LOWERED HIGHS JUST A
BIT... WITH AROUND 80 EXPECTED NORTHWEST TO THE MID 80S EAST. LOWS
ARE EXPECTED TO RANGE FROM THE LOWER 60S NW TO UPPER 60S SE.

WITH REGARD TO THE SEVERE THREAT... DEEP LAYER SHEAR IS EXPECTED TO
INCREASE AT TIMES TO AROUND 35 TO 50 KTS... ESPECIALLY ON
MONDAY/MONDAY AFTERNOON.  HOWEVER... INSTABILITY IS EXPECTED TO BE
WEAK TO VERY MODEST AT BEST... WITH GENERALLY POOR LAPSE RATES
THANKS TO THE RATHER MOIST AIR MASS. GIVEN THIS ALONG WITH THE
UNCERTAINTY OF TIMING THE INDIVIDUAL S/W AND ACTUAL PLACEMENT OF
THE FRONT... AM NOT VERY CONFIDENT ON WHEN/IF ANY SEVERE THREAT WILL
EXIST. HOWEVER... IF WE ARE ABLE TO GENERATE ENOUGH INSTABILITY
COUPLED WITH A DISTURBANCE MOVING THROUGH DURING PEAK HEATING THEN
WE COULD SEE A LEAST SOME ISOLATED SEVERE STORMS... WITH PRECIP
LOADED DOWNBURST THE MAIN THREAT. THOUGH... WITH A FRONT IN THE AREA
WITH WAVES OF LOW PRESSURE TRACKING ALONG IT COUPLED WITH THE
INCREASE FLOW ALOFT AND PEAK HEATING WE COULD CONCEIVABLE HAVE A
VERY SMALL THREAT FOR A WEAK/BRIEF TORNADO (BEST SMALL CHANCE ACROSS
THE COASTAL PLAIN). HOWEVER... THE MAIN THREAT TO LIFE AND PROPERTY
APPEARS IT WILL LIKELY BE FROM LOCALIZED FLASH FLOODING...
ESPECIALLY IN URBAN AREAS ACROSS THE EASTERN HALF OF THE AREA.  -BSD

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
AS OF 305 PM SATURDAY...

MID/UPPER LEVEL TROUGH IS EXPECTED TO WEAKEN... WITH THE MAIN TROUGH
AXIS SHIFTING TO THE EAST OF CENTRAL NC MIDWEEK INTO NEXT WEEKEND.
AT THE SURFACE THE WEAKENING BOUNDARY IS EXPECTED TO REMAIN NEAR THE
COAST WHILE DISSIPATING. THIS WILL RESULT IN A WEAK SURFACE PRESSURE
PATTERN ACROSS THE AREA... UNTIL SURFACE HIGH PRESSURE TO THE NORTH
OF THE REGION SHIFTS OFFSHORE NEXT WEEKEND RESULTING IN AN IMPROVING
SOUTHERLY LOW LEVEL FLOW. GIVEN AN EXPECTED LACK OF UPPER LEVEL
FORCING AND ONLY WEAK TO VERY MODEST AFTERNOON INSTABILITY AND WEAK
SURFACE PATTERN WILL CONTINUE ONLY A MENTION OF SLIGHT CHANCE POPS
FOR EACH AFTERNOON. EXPECT AFTERNOON HIGH TEMPS TO GENERALLY RANGE
FROM THE LOWER TO MID 80S... WITH SOME UPPER 80S POSSIBLE LATE IN
THE LATE WEEK/WEEKEND TIMEFRAME ACROSS THE SOUTHEAST. EXPECT
OVERNIGHT LOWS TO GENERALLY BE IN THE MID TO UPPER 60S.

&&

.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
AS OF 145 PM SATURDAY...

A WEAK COLD FRONT BISECTING THE PIEDMONT SW-NE WILL DRIFT SEWD
ACROSS THE SANDHILLS AND COASTAL PLAIN THIS AFTERNOON. THIS BOUNDARY
INTERACTING WITH THE MOIST AND SLIGHTLY UNSTABLE AIR MASS AT THE
SURFACE WILL INITIATE AND SUSTAIN SCATTERED CONVECTION THIS
AFTERNOON THROUGH EARLY THIS EVENING. IN VICINITY OF THE SHOWERS AND
THUNDERSTORMS EXPECT INSTANCES OF MVFR CONDITIONS ALONG WITH WIND
GUSTS NEAR 30KTS. AWAY FROM THE SHOWERS AND STORMS...EXPECT VFR
CONDITIONS. FOR NOW...WILL HAVE VCSH AT MOST OF THE TAFS THROUGH 23Z
BUT AMEND TO TEMPO OR PREDOMINATE ONCE CONVECTION DEVELOPS AND
TRENDS ARE NOTED.

THE FRONT WILL STALL EAST OF KFAY AND KRWI TONIGHT AND SUNDAY.
PLENTIFUL NEAR SURFACE MOISTURE TONIGHT SHOULD ALLOW AREAS OF LOW
CLOUDS AND FOG TO DEVELOP AFTER MIDNIGHT...POSSIBLY LEADING TO
IFR/LIFR CONDITIONS. FOG/CLOUDS EXPECTED TO LIFT BY 14Z SUNDAY.

A BATCH OF SHOWERS AND T-STORMS SHOULD AFFECT CENTRAL NC LATE SUNDAY
AND SUNDAY NIGHT AS AN AREA OF LOW PRESSURE TRAVELS NEWD ALONG THE
STALLED SURFACE BOUNDARY. THE ADVERSE AVIATION CONDITIONS ARE MORE
LIKELY NEAR KFAY...KRWI AND POSSIBLY KRDU THAN AT THE TRIAD
TERMINALS. AFTER 06Z MONDAY...AREAS OF LOW CLOUDS AND FOG WILL
LIKELY DEVELOP...LEADING TO IFR/LIFR CONDITIONS THAT MAY PERSIST TIL
14Z MONDAY. IN ADDITION...ANOTHER AREA OF LOW PRESSURE WILL APPROACH
FROM THE SOUTHWEST EARLY MONDAY MORNING...POSSIBLY SPREADING SHOWERS
BACK INTO CENTRAL NC PRIOR TO DAYBREAK.

AT THIS TIME...THE UPPER LEVEL TROUGH RESPONSIBLE FOR THE UNSETTLED
WEATHER PATTERN IS EXPECTED TO LIFT NWD TUESDAY-THURSDAY. THIS
SUGGEST A GRADUAL IMPROVEMENT (IE FEWER SHOWERS AND T-STORMS) DURING
THE LATER HALF OF THE FORECAST PERIOD.
