AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RALEIGH NC
254 PM EDT THU SEP 6 2012

.SYNOPSIS...
A WEAKENING COLD FRONT WILL DRIFT INTO CENTRAL NORTH CAROLINA THIS
AFTERNOON BEFORE BECOMING NEARLY STATIONARY TONIGHT. THE FRONT WILL
DISSIPATE FRIDAY. A STRONG COLD FRONT WILL APPROACH NORTH CAROLINA
SATURDAY. DRY AND COOLER CONDITIONS ARE EXPECTED IN THE WAKE OF THE
FRONT LATE SUNDAY THROUGH EARLY NEXT WEEK.

&&

.NEAR TERM /THROUGH FRIDAY NIGHT/...
AS OF 252 PM THURSDAY...

THROUGH TONIGHT:
SCATTERED SHOWERS AND THUNDERSTORMS HAVE DEVELOPED ACROSS CENTRAL NC
THIS AFTERNOON...MAINLY ALONG AND NORTH OF I-85...WHERE THE SURFACE
BOUNDARY IS LOCATED. THERE IS A CHANCE THAT AN ISOLATED SEVERE STORM
MAY DEVELOP...BUT FOR THE MOST PART EXPECT HEAVY RAIN WITH THIS
ROUND OF CONVECTION. MUCAPE VALUES THIS AFTERNOON ARE IN THE
1500-2000 J/KG RANGE...HOWEVER THERE IS LITTLE WIND SHEAR TO WORK
WITH. THE BEST LOW-LEVEL LAPSE RATES ARE ALONG THE NC COAST. THE
SURFACE TROUGH AND ASSOCIATE CONVECTION SHOULD SLOWLY MOVE SOUTH
THROUGH THE AREA THIS EVENING...SETTLING ALONG THE NC COAST LATER
TONIGHT/EARLY FRIDAY MORNING. HAVE INCREASED PRECIP CHANCES THIS
EVENING TO LIKELY ALONG THE NC/VA BORDER WHERE STORMS HAVE
DEVELOPED...AND KEPT LIKELY POPS IN THAT GENERAL VICINITY THROUGH
01Z. EXPECT IMPROVING CONDITIONS FROM NW TO SE AS NOCTURNAL
STABILIZATION OCCURS...AND SHOWERS TO BE LIMITED TO THE SOUTHEAST
ALONG THE SURFACE TROUGH FRIDAY MORNING. OVERNIGHT LOWS IN THE MID
60S NW TO NEAR 70 SE.

FRIDAY AND FRIDAY NIGHT:
THE SURFACE TROUGH IS EXPECTED TO STALL ALONG THE NC COAST THROUGH
FRIDAY...YIELDING A SLIGHT CHANCE FOR WIDELY SCATTERED SHOWERS AND
STORMS TO DEVELOP ACROSS THE EASTERN HALF OF THE AREA...WITH BEST
CHANCES FARTHER EAST. RIDGING TO THE WEST WILL LIKELY KEEP THE
WESTERN HALF OF THE AREA DRY FRIDAY AND FRIDAY NIGHT. THERE IS A
SLIGHT CHANCE FOR SOME SHOWERS TO DEVELOP ACROSS THE FAR NW BEFORE
SUNRISE SATURDAY AHEAD OF THE COLD FRONT APPROACHING THE AREA. HIGH
TEMPS IN THE UPPER 80S TO NEAR 90...WITH OVERNIGHT LOWS IN THE UPPER
60S TO LOW 70S FROM NW TO SE.

&&

.SHORT TERM /SATURDAY AND SATURDAY NIGHT/...
AS OF 245 PM THURSDAY...

AS A FAIRLY DEEP UPPER LEVEL TROUGH AND ASSOCIATED SURFACE COLD
FRONT APPROACH AND MOVE THROUGH THE AREA THIS WEEKEND...DECENT RAIN
CHANCES WILL RETURN TO THE REGION FOR SATURDAY. THERE ARE STILL SOME
MINOR TIMING ISSUES...BUT MODELS ARE IN GENERAL AGREEMENT WITH THE
COLD FRONT MOVING THROUGH THE AREA LATE SATURDAY INTO SUNDAY.
THEREFORE...WILL SHOW INCREASING PRECIP CHANCES FROM WEST TO EAST
SATURDAY INTO SATURDAY NIGHT AS A PREFRONTAL TROUGH INTERACTS WITH A
VERY MOIST AIR MASS (PWATS EXCEEDING 2 INCHES)...WITH PRECIP ENDING
FROM WEST TO EAST OVERNIGHT...BRINGING MOSTLY DRY CONDITIONS TO THE
FORECAST AREA BY SUNDAY MORNING. EVEN THOUGH THE BEST FORCING IS
PROGGED TO REMAIN NORTH OF THE AREA...BULK SHEAR OVER OUR AREA IS
EXPECTED TO BE ON THE ORDER OF 30-40 KNOTS AND WEAK TO MODERATE
INSTABILITY IS EXPECTED TO DEVELOP DURING THE AFTERNOON HOURS. THE
MAIN ISSUE WITH REGARD TO A SEVERE THREAT WILL BE THE ULTIMATE
TIMING OF THE PRECIP AS THE NAM BRINGS IN THE MAIN LINE DURING PEAK
HEATING AND THE SLIGHTLY SLOWER GFS AND ECMWF SHOW THE MAIN BAND OF
SHOWERS AND THUNDERSTORMS COMING THROUGH DURING THE EVENING HOURS.
NEVERTHELESS...WILL CONTINUE TO MAKE MENTION OF A FEW STRONG TO
SEVERE STORMS WITH THE PRIMARY THREAT OF DAMAGING WIND IN THE HWO.
ONE LAST DAY OF ABOVE NORMAL TEMPS ARE EXPECTED BEFORE THE FRONT
MOVES THROUGH...WITH HIGH TEMPS GENERALLY IN THE MID/UPPER 80S TO
NEAR 90 DEGREES. OVERNIGHT LOWS WILL DEPEND ON HOW QUICKLY THE
PRECIP MOVES OUT AND SOME DRIER AIR IS ABLE TO FILTER INTO THE
REGION...BUT FOR NOW WILL TREND LOWS FROM THE LOW 60S (MAYBE EVEN A
FEW UPPER 50S) ACROSS THE NORTHWEST TO MID/UPPER 60S FURTHER SOUTH
AND EAST.

&&

.LONG TERM /SUNDAY THROUGH THURSDAY/...
AS OF 245 PM THURSDAY...

FAIR WEATHER CONDITIONS ARE EXPECTED FOR THE ENTIRE LONG TERM PERIOD
AS HIGH PRESSURE BOTH AT THE SURFACE AND ALOFT MOVE IN BEHIND THE
STRONG UPPER TROUGH/SURFACE COLD FRONT. THIS WILL RESULT IN A
PROLONGED PERIOD OF DRY...MUCH COOLER AND LESS HUMID CONDITIONS
THROUGH AT LEAST THE MIDDLE OF NEXT WEEK AND MORE FALL-LIKE
TEMPERATURES WILL PREVAIL...WITH HIGHS EXPECTED TO BE IN THE UPPER
70S TO LOWER 80S...AND OVERNIGHT LOWS IN THE UPPER 50S TO NEAR 60
DEGREES.

&&

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

24-HR TAF PERIOD:
SCATTERED SHOWERS AND THUNDERSTORMS HAVE DEVELOPED OVER THE AREA
OVER THE PAST HOUR OR SO. STORMS ARE POSSIBLE AT ALL TAF SITES...
THOUGH PRIMARILY AT THE GSO/RDU/RWI TERMINALS BETWEEN 18Z THIS
AFTERNOON AND 03Z FRIDAY. WITH THE EXCEPTION OF WHERE ISOLATED TO
SCATTERED SHOWERS AND THUNDERSTORMS DEVELOP...EXPECT MAINLY VFR
CONDITIONS THIS AFTERNOON. LIGHT WINDS AND CLEARING SKIES OVERNIGHT
EXPECT SUB-VFR FOG TO DEVELOP BETWEEN 06Z AND 12Z FRIDAY. EXPECT VFR
CONDITIONS AFTER SUNRISE FRIDAY THROUGH THE END OF THE TAF PERIOD.

LOOKING AHEAD:
ASIDE FROM A LOW PROBABILITY OF ISOLD CONVECTION AT THE FAY/RWI TAF
SITES FRIDAY AFTERNOON...EXPECT VFR CONDITIONS TO PREVAIL. MVFR/IFR
CEILINGS WILL BE POSSIBLE BY SUNRISE SATURDAY MORNING AS SOUTHERLY
LOW-LEVEL FLOW STRENGTHENS AHEAD OF AN APPROACHING FRONT. ADVERSE
AVIATION CONDITIONS WITH WIDESPREAD SHOWERS AND THUNDERSTORMS ARE
EXPECTED SATURDAY AFTERNOON INTO SUNDAY MORNING AS A DEEP UPPER
LEVEL TROUGH AND ASSOCIATED COLD FRONT PROGRESS EAST THROUGH THE
CAROLINAS. EXPECT DRY/VFR CONDITIONS TO RETURN IN THE WAKE OF THE
FRONT SUNDAY AFTERNOON THROUGH EARLY NEXT WEEK AS HIGH PRESSURE
BUILDS OVER THE REGION. -VINCENT
