AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RALEIGH NC
300 PM EDT SUN JUL 31 2011

.SYNOPSIS...
AN UPPER DISTURBANCE WILL MOVE SOUTH ACROSS THE STATE LATE THIS
AFTERNOON AND EVENING. THIS DISTURBANCE WILL INTERACT WITH A WEAK
SURFACE BOUNDARY OVER CENTRAL NC...PRODUCING NUMEROUS SHOWERS AND
THUNDERSTORMS THROUGH TONIGHT. DRIER AIR WILL BUILD INTO THE AREA ON
MONDAY WITH MODERATING TEMPERATURES THROUGH THE WORK WEEK BEFORE A
WEAK FRONT APPROACHES THE STATE LATE WEDNESDAY.

&&

.NEAR TERM /THROUGH MONDAY NIGHT/...
AS OF 230 PM SUNDAY...
THIS AFTERNOON AND TONIGHT:
MID LEVEL SHORTWAVE VORT ENERGY EMBEDDED IN THE NWLY FLOW ON THE
SOUTHERN PERIPHERY OF THE ONTARIO SHORTWAVE TROUGH WILL MOVE
SOUTHEAST ACROSS THE NORTHEAST/NORTHERN MID-ATLANTIC REGION THIS
AFTERNOON AND EVENING. THE VORT BECOMES INCREASINGLY MORE CHANNELED
AS IT SAGS SOUTH INTO THE AREA WITH A 50 KT JET ACCOMPANYING THE
WEAK SHEAR AXIS. AT THE SURFACE...THE LACK OF APPRECIABLE HEIGHT
FALLS OVER THE SOUTHERN MID-ATLANTIC WILL ALLOW A SURFACE COLD FRONT
TO STALL NORTHERN VA/WV/KENTUCKY.

BLENDED TPW SHOWS A MOIST 2.0 TO 2.25" PWAT AIRMASS IN PLACE ACROSS
THE CAROLINAS...SOUTH OF THE STALLING OUT SURFACE FRONT ACROSS THE
VIRGINIAS...WITH A WEAK SFC CONVERGENCE TROUGH AXIS BISECTING THE
FORECAST AREA...LIKELY THE REMNANTS OF LAST NIGHTS CONVECTION.
CONVECTION COVERAGE HAS BLOSSOMED OVER THE PAST COUPLE OF HOURS
AS THE UPPER SHEAR AXIS APPROACHES...COMBINED WITH DAYTIME
HEATING AND RESULTANT DESTABILIZATION AS SPC MESOANALYSIS
SHOWING A 1000 TO 1500 JOULES OF MLCAPE ACROSS THE PIEDMONT...WITH
STRONG DESTABILIZATION OF 2000 TO 3000 JOULES ACROSS THE EXTREME
SOUTHEAST.

ANEMIC WIND FIELDS(BULK SHEAR <= 20KTS;0-3KM SHEAR <=10KTS)...WEAK
MID LEVEL LAPSE RATES AND LINGERING WARM TEMPERATURES ALOFT WILL
LIMIT SEVERE THREAT WITH AN ISOLATED WET MICROBURST OR TWO POSSIBLE.
INSTEAD THE MAIN THREAT WILL BE LOCALIZED FLOODING...ESPECIALLY IN
URBAN OR LOW-LYING AREAS FROM SLOW MOVING/TRAINING STORMS.

HEAVY SHOWERS AND STORMS COULD PERSIST WELL INTO THE OVERNIGHT
HOURS...WITH A CONTINUED THREAT OF MINOR FLOODING DURING THE EVENING
BEFORE DRIER AIR ALOFT BEGINS TO SPREAD IN FROM THE NORTHWEST AFTER
MIDNIGHT WITH THE PASSAGE OF THE MOIST MID-LEVEL SHEAR AXIS. WILL
GRADUALLY TAPER OFF POPS FROM NW TO SE...KEEPING A CHANCE OF POPS
ACROSS THE SOUTHEAST THROUGH DAYBREAK. WITH FRONT STALLING SOUTH OF
THE AREA AND WIDESPREAD CLOUDINESS....EXPECT ANOTHER WARM NIGHT WITH
RAIN COOLED LOWS MATCHING CLOSELY TO SFC DEWPOINTS. OVERNIGHT LOWS
IN THE LOWER TO MID 70S.

MONDAY AND MONDAY NIGHT:
MODELS ARE IN GOOD AGREEMENT WITH THE TIMING OF THE MOIST LOWER/MID
TROUGH PASSAGE MOVING SOUTHEAST OF THE AREA BY 15Z MONDAY. OUTSIDE
OF ISOLATED CONVECTION DEVELOPING ALONG NORTHERN/WESTERN THETA-E
GRADIENT ACROSS THE SANDHILLS...EXPECT PRECIP/CONVECTION TO BE OUT
OF THE AREA BY MIDDAY. WITH SKIES BECOMING PARTLY TO MOSTLY SUNNY
AND LITTLE AIRMASS CHANGE WITH THICKNESSES IN THE 1430 METER
RANGE...HIGHS SHOULD BE MOSTLY IN THE LOWER 90S.

MODELS CONTINUE TO SHOW A SIGNIFICANT UPPER PV DISTURBANCE
DIVING SOUTHEAST ACROSS THE AREA MONDAY EVENING BETWEEN 00 TO 06Z.
HOWEVER MODELS DEPICT A FAIRLY DRY COLUMN...MAKING IT DIFFICULT TO
INCLUDE ANY POPS AT THIS TIME. LOWS MONDAY NIGHT 70 TO 75.

&&

.SHORT TERM /TUESDAY THROUGH WEDNESDAY/...
AS OF 300 PM SUNDAY...

THE LATEST GFS PROVIDES FOR MODERATELY STRONG SHORTWAVES MOVING
THROUGH CENTRAL NORTH CAROLINA IN THE NORTHWEST FLOW...AROUND THE
UPPER RIDGE...LATE TUESDAY NIGHT AND INTO WEDNESDAY. THESE WAVES MAY
BE A RESULT OF CONVECTIVE FEEDBACK...HOWEVER...THE NAM ALSO
FORECASTS A MODEST MID-LEVEL SHORTWAVE SKIRTING TO THE NORTH AND
NORTHEAST OF CENTRAL NORTH CAROLINA LATE TUESDAY NIGHT AND EARLY
WEDNESDAY. AFTER WHAT SHOULD BE A STABLE DAY TUESDAY...WITH NAM AND
GFS BUFR SOUNDINGS SHOWING AMPLE CIN UNDER A RELATIVELY DRY AIR MASS
AS PRECIPITABLE WATER VALUES ARE BELOW 2 INCHES...AND K INDICES ARE
LESS THAN 30...BOTH THE NAM AND THE GFS SUGGEST AN INCREASE IN AT
LEAST MID-LEVEL CLOUDS TUESDAY NIGHT INTO WEDNESDAY. MOISTURE
INCREASES TUESDAY NIGHT INTO WEDNESDAY ON BOTH MODELS...WITH A
GRADUAL INCREASE IN 850MB THETA-E ON THE NAM AND A MORE RAPID
INCREASE ON THE GFS...WITH PRECIPITABLE WATER VALUES ON THE LATTER
CLIMBING TO WELL OVER TWO INCHES BY 18Z WEDNESDAY. ENOUGH MOISTURE
IS PRESENT IN THE MID-LEVELS TO PRODUCE A SMALL CHANCE OF A SHOWER
OVERNIGHT TUESDAY AS THE LOW-LEVEL MOISTENS COINCIDENT WITH THE
APPROACH OF A MID-LEVEL WAVE.

ON WEDNESDAY...DESPITE THE STRENGTH OF THE MID-LEVEL WAVE ON THE
GFS...THAT MODEL AGREES WITH THE NAM THAT THE GREATEST INSTABILITY
SHOULD LIE MAINLY ALONG AND EAST OF U.S. 1. LIFTED INDICES ON THE
NAM ONLY SLIGHTLY FALL BELOW 0C...BUT THE GFS CAPE APPROACHES
1000J/KG TO THE SOUTH...AND THE NAM IS NEAR 500J/KG OVER THE SAME
AREA. BUFR SOUNDINGS SHOW THE BEST INSTABILITY OVER AND NEAR KFAY
AND KRWI...PARTICULARLY ON THE GFS...AND FOR THIS FORECAST WILL
INTRODUCE A SLIGHT CHANCE OF SHOWERS AND THUNDERSTORMS MAINLY ALONG
AND EAST OF A LINE FROM ABOUT WADESBORO TO ROANOKE RAPIDS.

GUIDANCE HAS TRENDED LOWER WITH HIGH TEMPERATURES FOR WEDNESDAY...
AND IF THE NAM AND GFS VERIFY WITH A GREATER DEGREE OF AT LEAST
MID-LEVEL CLOUDS...HIGHS WILL STRUGGLE TO APPROACH TRIPLE DIGITS IN
CENTRAL NORTH CAROLINA. HIGHER DEW POINTS WEDNESDAY...ESPECIALLY
OVER THE SANDHILLS AND SOUTHERN COASTAL PLAIN...COULD STILL RESULT
IN MAXIMUM APPARENT TEMPERATURES NEAR HEAT ADVISORY CRITERIA. HIGH
TEMPERATURES MAY ACTUALLY BE CLOSER TO 100 IN SOME LOCATIONS TUESDAY
WITH MORE SUN EXPECTED AND A DRIER AIR MASS OVERALL...ALTHOUGH ON
TUESDAY DEW POINTS SHOULD SHOW SOME MIXING DURING THE AFTERNOON.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
AS OF 300 PM SUNDAY...

WITH THE CONSENSUS OF THE LONG-TERM GUIDANCE SHOWING THE UPPER RIDGE
CENTERED IN VICINITY OF ARKANSAS...AND EXTENDING EAST INTO NORTH
CAROLINA...THE PRIMARY CONCERN AT LEAST THROUGH THURSDAY...AND
POSSIBLY EVEN INTO FRIDAY...WILL BE THE HOT AND HUMID CONDITIONS.
1000-850MB THICKNESSES EXTEND AS HIGH AS 1450-1455M...WHICH WOULD
AGAIN PUT CENTRAL NORTH CAROLINA SOLIDLY IN THE POTENTIAL FOR HIGH
TEMPERATURES IN THE MID 90S TO JUST ABOVE 100 DEGREES. THICKNESSES
ARE FORECAST TO FALL SLIGHTLY FRIDAY COMPARED TO WEDNESDAY AND
THURSDAY. PRECIPITABLE WATER VALUES SHOULD ALSO BE IN VICINITY OF
TWO INCHES...AND DESPITE THE RIDGE OVERHEAD...IN A SYNOPIC REGIME
JUST SOUTH OF A SURFACE FRONTAL ZONE AS HIGH PRESSURE TRIES TO NOSE
SOUTH FROM THE LOWER GREAT LAKES...AT LEAST ISOLATED THUNDERSTORMS
WILL BE POSSIBLE THURSDAY.

THE RIDGE STARTS TO RETREAT WEST LATE IN THE WEEK...AND THIS SHOULD
RESULT IN GRADUALLY INCREASING DIFFLUENCE ALOFT AS AN UPPER TROUGH
DEEPENS SOMEWHAT OVER THE ATLANTIC SEABOARD. GFS ENSEMBLE MOS
SUGGESTS INCREASING CHANCES FOR SHOWERS AND THUNDERSTORMS DURING
LATE WEEK AND INTO THE WEEKEND...WHICH SEEMS REASONABLE CURRENTLY
BASED ON THE UPPER PATTERN...LINGERING MOISTURE...AND SURFACE
TROUGHINESS FORECAST OVER CENTRAL NORTH CAROLINA. COARSE MODEL
SOUNDINGS FROM THE GFS AND ECMWF AGREE WITH THE MOS ENSEMBLE POPS
THAT THE HIGHEST CHANCES FOR RAIN CURRENTLY IN THE FORECAST WILL BE
SATURDAY...WITH SOME EVIDENCE SUGGESTING CENTRAL NORTH CAROLINA
COULD START TO DRY SOME FROM THE NORTHWEST ON DAY SEVEN. FOR NOW...
WILL FORECAST THE HIGHEST CHANCES FRIDAY MAINLY ALONG AND NORTH OF
U.S. 64 CLOSER TO THE FRONTAL ZONE...AND SCATTERED THUNDERSTORMS
THROUGHOUT CENTRAL NORTH CAROLINA SATURDAY. WILL CONTINUE CHANCES
FOR SHOWERS AND THUNDERSTORMS SUNDAY...WITH THE HIGHER CHANCES THEN
MAINLY SOUTH OF A LINE FROM KIXA TO KVUJ. SINCE THERE WILL BE MORE
CLOUDS ANTICIPATED OVER THE WEEKEND ALONG WITH A MORE UNSETTLED AIR
MASS...HIGH TEMPERATURES SHOULD BE A FEW DEGREES COOLER OVER THE
WEEKEND COMPARED TO VALUES THAT ARE ANTICIPATED WITH MORE RIDGING
OVERHEAD. THIS IS SUPPORTED BY THE GFS MOS ENSEMBLES AND MOS TRENDS.

&&

.AVIATION /18Z SUNDAY THROUGH SATURDAY/...
AS OF 140 PM SUNDAY...
SHOWERS AND THUNDERSTORMS WILL BECOME NUMEROUS ACROSS THE AREA THIS
AFTERNOON THROUGH LATE THIS EVENING AS AN UPPER DISTURBANCE SAGS
SOUTH THROUGH THE AREA. HEAVY RAIN WILL CAUSE PERIODS OF IFR TO MVFR
RESTRICTIONS WILL BE POSSIBLE WITH ANY STRONG STORM.

CONVECTION WILL DIMINISH FROM THE NORTHWEST IN THE TRIAD AREA BY
AROUND MIDNIGHT...WITH LINGERING CONVECTION IN THE EAST THROUGH
SUNRISE BEFORE THE DEEP MOISTURE AXIS AND UPPER DISTURBANCE MOVE
SOUTHEAST OF THE AREA. MVFR TO IFR CONDITIONS WITH AREAS OF FOG ARE
POSSIBLE OVERNIGHT AFTER THE RAIN ENDS...ESPECIALLY ACROSS NORTHERN
TAF SITES WHERE CLEARING COULD OCCUR. OTHERWISE...VFR CONDITIONS
EXPECTED ON MONDAY.

BEYOND THE 24 HOUR TAF PERIOD:
CENTRAL NC WILL REMAIN ON THE EASTERN PERIPHERY OF THE DRY/HOT AIR
RIDGE OVER THE CENTRAL US. THIS WILL SUPPORT PREDOMINATELY VFR
CONDITIONS WITH ISOLATED AFTERNOON STORMS POSSIBLE THROUGH LATE IN
THE WORK WEEK. RAIN CHANCES SHOULD INCREASE ON SATURDAY WITH THE
APPROACH OF AN UPPER LEVEL WAVE FROM THE WEST.

&&
