AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RALEIGH NC
235 PM EDT TUE AUG 16 2005

.SHORT TERM (TONIGHT THROUGH FRIDAY)...

THROUGH TONIGHT: AS EXPECTED... NUMEROUS STORMS HAVE DEVELOPED ON
THE HIGHER TERRAIN THIS AFTERNOON WITH MORE SCATTERED ACTIVITY IN
THE COASTAL PLAIN AND SANDHILLS ALONG THE WEAK SURFACE MOISTURE
CONVERGENCE AXIS & INSTABILITY GRADIENT. THE MOUNTAIN STORMS WILL
DROP INTO THE NORTHWEST PIEDMONT OVER THE NEXT FEW HOURS
NECESSITATING LIKELY POPS THERE THROUGH EARLY EVENING. DAMAGING WIND
GUSTS ARE POSSIBLE AS THE INITIALLY VERY WEAK WIND PROFILE IMPROVES
SOMEWHAT... AND STEEP LOW LEVEL LAPSE RATES ALONG WITH POTENTIAL LOW
LEVEL DRYING FROM THE INCREASING WSW WINDS COULD EXACERBATE
DOWNDRAFTS. THEN WITH THE MESOSCALE VORTICITY CENTER NOW CROSSING KY
ALONG THE SYNOPTIC FRONT EXPECTED TO TRACK ALONG THE NC/VA BORDER
TONIGHT ACCOMPANIED BY UPPER DIVERGENCE NOTED ON THE 345K SURFACE...
WILL EXTEND LIKELY POPS ACROSS THE REST OF THE NORTHERN & NORTHEAST
CWA OVERNIGHT. LOWS 71-75.

WED THROUGH FRI: WILL CARRY LIKELY POPS IN THE EAST THROUGH MIDDAY
WED WITH LOWER CHANCES ELSEWHERE... TAPERING OFF IN THE AFTERNOON AS
THE FRONT DROPS TO OUR SOUTH & MORE STABLE AIR WORKS INTO THE NORTH
WITH INCREASINGLY DIFFLUENT 850 MB FLOW. HIGHS 83-90 WED... BUT
CONFIDENCE IS NOT HIGH IN THESE NUMBERS AS THEY WILL DEPEND ON HOW
MUCH IF ANY CLEARING TAKES PLACE IN THE AFTERNOON. THE FRONT WILL
LIKELY HANG UP ALONG COASTAL NC ACROSS SC THU AS THE WEAK HIGH
PRESSURE AREA NOSES IN FROM THE NORTH... & WILL LEAVE JUST LOW
CHANCE POPS THU MAINLY ACROSS THE SOUTH WITH VARIABLY CLOUDY SKIES.
HIGHS 83-88. FORECAST GROWS MORE UNCERTAIN BY FRI WITH THE GFS
HANGING ONTO MUCH MORE SURFACE RIDGING DOWN THE EASTERN SLOPES. TEND
TO PREFER THE MILDER NAM SOLUTION WITH THE SURFACE FRONT DISSIPATING
AND A STRONGER MID LEVEL WAVE CROSSING THE GREAT LAKES TENDING TO
SHOVE THE PARENT HIGH OUT TO SEA... SINCE IT LOOKS LIKE THE GFSS
FEEDBACK CONTAMINATION CAUSES THIS WAVE TO LOSE DEFINITION THUS
KEEPING THE PARENT HIGH IN PLACE. WILL HAVE CHANCE POPS AND HIGHS IN
THE MID 80S TO NEAR 90.

&&

.LONG TERM (FRIDAY NIGHT THROUGH TUESDAY)...

MID LEVEL RIDGING APPEARS TO DOMINATE THE REGION FRI NIGHT THROUGH
SAT. THE ECMWF/GFS MODELS BOTH INDICATE THE FRONT WELL TO OUR SOUTH
WITH SURFACE HIGH PRESSURE AREA TRYING TO NOSE IN FROM THE NORTH...
HOWEVER SINCE THE GFS APPEARS TO BE OVERZEALOUS WITH ITS COOL
NOSE... WILL LEAN MORE TOWARD CLIMATOLOGY FOR MAXES... 86-91. THEN
SUN THROUGH MON... THE ANOMALOUS UPPER VORTEX TRACKING ACROSS
SOUTHEAST CANADA IS EXPECTED TO BE DEEP ENOUGH (ACCORDING TO THE
ECMWF/GFS) TO PUSH A FRONT SOUTHWARD INTO THE REGION... AND A
PREFRONTAL TROUGH OVER THE PIEDMONT IS LIKELY TO PRECEDE IT.
THEREFORE WILL RESUME POPS SUNDAY AFTERNOON THROUGH MONDAY. TEMPS A
BIT ABOVE NORMAL SUNDAY THEN HIGHS SHOULD DROP BACK NEAR OR A LITTLE
BELOW NORMAL MONDAY WITH EXPECTATIONS OF COPIOUS CLOUD COVER. TUE
FORECAST IS A WILD CARD WITH UNCERTAINTY AS TO HOW FAR SOUTHWARD THE
FRONT PUSHES... WITH ONLY A 1020 MB HIGH PUSHING SOUTHWESTWARD
BEHIND IT. THE GFS HAS BEEN TRENDING SLIGHTLY NORTH WITH THE FRONT
AND ASSOCIATED PRECIP. WITH SYNOPTIC SCALE FRONTAL PASSAGES SO RARE
IN NC THIS TIME OF YEAR... WILL HOLD THE FRONT ACROSS NC AND
CONTINUE CHANCE POPS TUE... PRIMARILY DURING THE AFTERNOON AND
EVENING... AND SLIGHTLY HIGHER ACROSS THE SOUTH & SOUTHEAST WHERE
ANY LEE DRYING EFFECTS FROM WESTERLY 850 MB WINDS WILL BE LESSENED.
HIGHS TUE 85-89.

&&

.AVIATION...

SHOWERS AND THUNDERSTORMS DEVELOPING ALONG THE BLUE RIDGE WILL MOVE
EAST INTO THE AREA...REACHING THE TRIAD BETWEEN 20 AND 22Z. THE
STORMS COULD PRODUCE STRONG WIND GUSTS...AND TAFS WILL MENTION A
TEMPO WITH IFR VIS/MVFR CIGS AND WIND GUSTS UP TO 30 KTS. RUC MODEL
SHOWS UPPER DIVERGENCE PERSISTING AND A VORTICITY CENTER MOVING EAST
ACROSS THE NORTHERN PIEDMONT THROUGH THE EVENING HOURS...SO STORMS
WILL LIKELY AFFECT RDU AND RWI BETWEEN 22Z AND 04Z. FAY MAY SEE AN
ISOLATED STORM BUT COVERAGE WILL BE GREATEST TO THE NORTH. AREAS
THAT RECEIVE RAIN ARE LIKELY TO HAVE IFR FOG OVERNIGHT. WINDS SHIFT
TO NORTH-NORTHEAST TOMORROW MORNING AS A SURFACE BOUNDARY MOVES INTO
THE AREA.
