AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RALEIGH NC
ISSUED BY NATIONAL WEATHER SERVICE BLACKSBURG VA
126 PM EDT WED APR 27 2011

.SYNOPSIS...
SOUTHERLY FLOW WILL CONTINUE TO PUMP A WARM MOIST AIR MASS INTO THE
CAROLINAS TODAY AHEAD OF A COLD FRONT THAT WILL CROSS CENTRAL
NORTH CAROLINA ON THURSDAY.

&&

.NEAR TERM /THROUGH TONIGHT/...
AS OF 125 PM WEDNESDAY...

TORNADO WATCH 233 ISSUED FOR THE ENTIRE AREA UNTIL 8 PM TODAY.
NO OTHER CHANGES TO THE GRIDS EXCEPT ADDING DAMAGING WINDS/LARGE
HAIL POTENTIAL WITH ANY THUNDERSTORM.

PREV DISCUSSION...
SCATTERED SHOWERS HAVE DEVELOPED RAPIDLY ALONG THE I 95 CORRIDOR
THIS MORNING IN AN AREA OF LOW LEVEL MOISTURE CONVERGENCE THAT
SHOWS UP WELL ON THE SPC MESOSCALE ANALYSIS PAGE. THESE SHOWERS
ARE DEVELOPING DESPITE PLENTIFUL LOW CLOUDS ACROSS THE CWA AND
LITTLE HEATING. SHOWS HOW UNSTABLE AND WEAKLY CAPPED THE AIRMASS
IS DUE TO VERY MOIST CONDITIONS...WITH PWATS WELL ABOVE AVERAGE. I
HAVE INCREASED POPS THIS MORNING TO ACCOUNT FOR SCATTERED COVERAGE
IN THE EASTERN CWA...THEN ALSO INCREASED POPS THIS AFTERNOON SO
THAT ALL AREAS WILL HAVE SCATTERED COVERAGE OF THUNDERSTORMS.
STILL A THREAT FOR ISOLATED SEVERE THUNDERSTORMS LATE THIS
AFTERNOON...WITH MODIFIED GSO SOUNDING INDICATING A 1500 J/KG CAPE
LIKELY AND STRONG ENOUGH WIND FIELDS TO SUPPORT MULTICELL
CLUSTERS. DAMAGING WINDS WOULD BE THE MAIN THREAT...WITH LARGE
HAIL POSSIBLE IN THE STRONGEST STORMS. CURRENT HIGH RESOLUTION
MODELS ARE HINTING THAT THE NW PIEDMONT WILL HAVE THE BEST
COVERAGE LATE THIS AFTERNOON...BUT MODEL FIELDS HAVE LITTLE TO
FOCUS CONVECTION ON- WILL LIKELY BE ANY AREAS WITH EVEN WEAK LOW
LEVEL CONVERGENCE. WITH SUCH HIGH PWATS...ANY THUNDERSTORMS WILL
HAVE HEAVY DOWNPOURS...BUT SHOULD BE MOVING ALONG KEEPING HEAVY
DOWNPOURS BRIEF.

LOOKING AT THE MORNING THICKNESS FROM THE GSO SOUNDING...EVEN
PARTIAL SUNSHINE SUPPORTS THE CURRENT HIGH TEMP FCST OF MAINLY MID
80S...SO ONLY MINOR ADJUSTMENTS TO HOURLY TEMPS WERE MADE. HAD TO
RAISE DEWPOINTS A FEW DEGREES THOUGH. WILL BE A MUGGY AFTERNOON.

AS OF 305 AM WEDNESDAY...

CURRENTLY WATER VAPOR AND INFRARED SATELLITE IMAGERY SHOWS ANY
REMAINING CONVECTION DYING OUT OVER THE COASTAL PLAIN OR MOVING OFF
OF THE NORTH CAROLINA COAST. SOME SCATTERED THUNDERSTORMS HAVE
DEVELOPED JUST EAST OF THE MOUNTAINS AND ARE MAKING PROGRESS TO THE
NORTHEAST. WILL EXPECT THE MAJORITY OF THESE STORMS TO REMAIN WEST
OF THE CWA UNTIL AT LEAST DAYBREAK BUT CANT RULE OUT A SHOWER OR
THUNDERSTORM ROAMING INTO THE TRIAD. MOST PLACES NOW SHROUDED OVER
IN MVFR STRATUS IN THE 1-2 KFT RANGE AND THEREFORE WILL GO WITH
RELATIVELY UNIFORM LOWS 65-67.

EXPECT SOUTHERLY FLOW TO CONTINUE TODAY AS CENTRAL NC REMAINS IN
BETWEEN THE SUBTROPICAL HIGH OFFSHORE AND THE APPROACHING FRONTAL
SYSTEM TO THE WEST. A SOMEWHAT DRIER DAY THAN YESTERDAY AS UPPER
LEVEL HEIGHT RISES WILL BRING IN MORE SUBSIDENT CONDITIONS...MAKING
IT HARDER TO SUSTAIN CONVECTION. WATER VAPOR TO THE WEST CURRENTLY
INDICATES A DRY ZONE FROM THE GULF COAST NORTHWARD THROUGH WESTERN
NEW YORK THAT IS EXPECTED TO PROPAGATE WESTWARD OVER THE AREA LATER
ON TODAY. THAT BEING SAID...WE ARE IN A SLIGHT RISK FOR SEVERE
STORMS AND INSTABILITY WILL NOT BE A PROBLEM IF SOMETHING DOES BREAK
THROUGH THE CAP AND MID LEVEL LAPSE RATES ARE DECENT. EXPECT CHANCES
FOR THUNDERSTORM ACTIVITY TO INCREASE AS THE DAY GOES ON AS HEATING
INCREASES AND OMEGA ALSO BEINGS TO IMPROVE AHEAD OF THE APPROACHING
SYSTEM. CONDITIONS WILL BE BETTER ACROSS THE WESTERN PIEDMONT
THEREFORE WILL GO WITH SCATTERED THUNDERSTORMS BY LATE AFTERNOON
VERSUS MORE ISOLATED IN THE EAST. EXPECT HIGHS 84-88 ACROSS THE
AREA. EXPECTING LOWS TOMORROW NIGHT INTO THURSDAY MORNING TO BE
HIGHER THAN TONIGHT AS CLOUD COVER INCREASES AS THE SYSTEM
APPROACHES...67-71.

&&

.SHORT TERM /THURSDAY THROUGH SATURDAY/...
AS OF 305 AM WEDNESDAY...

     SEVERE THUNDERSTORMS WITH DAMAGING WINDS AND ISOLATED TORNADOES
POSSIBLE THURSDAY INTO THURSDAY EVENING...

THE BIGGEST CHANGE TO THE SHORT TERM FORECAST IN THIS PACKAGE WILL
BE THE TIMING OF THE FRONTAL SYSTEM. BOTH 0Z RUNS OF THE GFS AND THE
NAM INDICATE A SLOWER FRONTAL PASSAGE...NOW APPROACHING THE TRIAD
CLOSER TO 12Z...CROSSING THE TRIANGLE BY 18Z AND HEADING OFF TO THE
EAST SOMETIME AFTER 00Z FRIDAY...MAKING THE DIURNAL TIMING MORE
IDEAL FOR THIS EVENT. MODEL SOUNDINGS STILL INDICATE STRONG VEERING
OF THE WIND IN THE LOWER LEVELS WHILE BACKING WITH HEIGHT SETTING UP
FAVORABLE CONDITIONS FOR DAMAGING WINDS AND ISOLATED TORNADOES.
INSTABILITY ON THURSDAY AFTERNOON WILL BE GREATEST TO THE
EAST...UPWARDS OF 1500 J/KG BY THURSDAY AFTERNOON. AS FAR AS SHEAR
PARAMETERS GO...THE BEST 0-6 KM SHEAR WILL BE IN THE WEST AS THE
SYSTEM CROSSES THE AREA...BUT THE 0-1 KM SHEAR WILL BE MORE HEAVILY
FAVORED IN THE EAST. EXPECT THIS TO BE A DAMAGING WIND QLCS EVENT
WITH SOME EMBEDDED TORNADOES POSSIBLE. EXPECT THE TORNADO THREAT TO
INCREASE FURTHER EAST AS THE 0-1 KM SHEAR INCREASES BUT GIVEN THE
50+ KNOT LOW-LEVEL JET AND THE STRONG VEERING OF THE WINDS IN THE
LOW LEVELS...CAN NOT RULE OUT THE TORNADO THREAT IN THE WEST EITHER.
ALTHOUGH THE HAIL THREAT IS NON-ZERO...SKINNY CAPE PROFILES WILL
MAKE THE SEVERE HAIL THREAT MORE UNLIKELY. TEMPERATURES A LITTLE
TRICKY FOR THURSDAY BASED ON THE TIMING OF THE FRONT AND HOW
CONVECTION PLAYS OUT...79-83. AFTER THE FRONTAL PASSAGE EXPECT WINDS
TO SHIFT AROUND TO NORTHWESTERLY AND COLD AIR ADVECTION TO ENSUE.
QUITE A BIT COOLER THURSDAY NIGHT...49 NORTHWEST TO 54 SOUTHEAST.
-ELLIS

FRIDAY:
MID/UPPER LEVEL TROUGH AXIS ALONG WITH A SECONDARY COLD FRONT IS
EXPECTED TO SWING THROUGH THE AREA ON FRIDAY. HOWEVER... WITH LACK
OF ANY SIGNIFICANT MOISTURE THROUGH THE COLUMN EXPECT WE WILL ONLY
SEE ANY INCREASE IN CLOUD COVER ON FRIDAY AFTERNOON... WITH SKIES
BECOMING CLEAR BY SUNSET WITH THE LOSS OF HEATING AN SUBSIDENCE
BEHIND THE EXITING TROUGH. WITH A DEEP DRY DRY SUB CLOUD LAYER
EXPECTED ALONG WITH A WEST TO WEST-NORTHWESTERLY DOWNSLOPE FLOW...
EXPECT WE WILL SEE HIGH TEMPS IN THE MID TO UPPER 70S ACROSS CENTRAL
NC. -BSD

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
AS OF 1255 PM WEDNESDAY...

GENERALLY FOLLOWING AN HPC SOLUTION HERE WHICH LEANS TOWARD A BLEND
OF THE GFS/ECMWF TO END THE WEEKEND THEN MORE OF AN ENSEMBLE
SOLUTION THEREAFTER.

SAT NIGHT INTO SUNDAY WILL SEE RIDGE OVER THE AREA SHIFTING EAST AS
NEXT STORM SYSTEM WORKS INTO THE CENTRAL U.S. WITH A SPLIT FLOW
REGIME WITH ONE STRONG SHORTWAVE MOVING SLOWLY EAST ACROSS THE UPPER
MIDWEST AND THE SRN STREAM WAVE WORKING INTO THE LOWER MISSOURI
VALLEY AND SRN PLAINS BY MONDAY. AHEAD OF THIS SYSTEM WE SHOULD BE
DRY WITH INCREASING HUMIDITIES...AND TEMPS AS HIGHS BY MONDAY WILL
BE IN THE LOWER TO MID 80S. AS THE SRLY FLOW INCREASES MONDAY AND
THE COLD FRONT PUSHES INTO THE TN/OHIO VALLEYS...THE CHANCE OF
AFTN/EVENING THUNDERSTORMS INCREASES...WITH A BETTER CHANCE ARRIVING
MON NIGHT AS THE FRONT PROGESSES INTO CENTRAL NORTH CAROLINA.

THE CONFIGURATION OF THE UPPER AIR PATTERN AND FRONT SUGGESTS
POTENTIAL FOR A LINEAR STORM ORGANIZATION...AND SVR POTENTIAL WITH
WIND GUSTS. ALSO...WEAK WAVE OF LOW PRESSURE MOVING ALONG THE FRONT
MONDAY NIGHT COULD BACK THE LOW LVL FLOW ENOUGH TO INCREASE HELICITY
LEADING TO POTENTIAL TORNADIC THREAT. STILL EARLY TO CALL IT...BUT
SEEMS WE COULD BE LOOKING AT SOME SVR WX POTENTIAL IN THE MON-TUE
TIME FRAME...ALTHOUGH IF MAIN LINE COMES IN AT NIGHT...THIS MAY
LIMIT THE THREAT.

SHOULD SEE THINGS GETTING DRIER/COOLER BY MIDWEEK PER ENSEMBLE
SOLUTION...AS HIGH PRESSURE WORKS IN FROM THE WEST. A SLOWER ECWMF
SOLUTION WOULD DELAY THIS BY ANOTHER DAY AS IT TAKES ON A NEG TILT
TO THE UPPER TROUGH HANGING THE SFC FRONT UP ACROSS ERN NC.

&&

.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
AS OF 730 AM WEDNESDAY...

LOW STRATUS... MVFR AT KGSO/KINT AND IFR AT KFAY/KRDU/KRWI... IS
EXPECTED TO GRADUALLY LIFT THIS MORNING WITH DAYTIME HEATING... WITH
VFR CONDITIONS EXPECTED ACROSS ALL OF CENTRAL NC BY EARLY AFTERNOON.
IN ADDITION TO THE LOW STRATUS ISOLATED TO SCATTERED SHOWERS WILL BE
POSSIBLE ACROSS THE EASTERN TAF SITES THIS MORNING IN THE MOIST
SOUTHERLY FLOW. SOUTH TO SOUTHWESTERLY WINDS ARE EXPECTED TO
INCREASE THIS MORNING INTO THE AFTERNOON AS A STRONG COLD FRONT
APPROACHES THE REGION FROM THE WEST. THIS WILL RESULT IN SUSTAINED
WINDS IN THE 15 TO 20 MPH RANGE TODAY INTO TONIGHT... WITH WINDS
GUSTS OF UP TO 30 MPH POSSIBLE. IN ADDITION... WITH A WARM MOIST
ATMOSPHERE IN PLACE EXPECT WE WILL SEE AT LEAST ISOLATED SHOWERS AND
STORMS AGAIN LATER THIS AFTERNOON. THUS... HAVE INCLUDED CB IN THE
TAFS FOR THIS AFTERNOON. ANY SHOWER AND THUNDERSTORM ACTIVITY IS
EXPECTED TO DISSIPATE WITH THE LOSS OF DAYTIME HEATING.

THE AFOREMENTIONED COLD FRONT IS EXPECTED TO MOVE THROUGH CENTRAL NC
THURSDAY MORNING INTO THE AFTERNOON. LOW STRATUS/SUB VFR CIGS WILL
BE POSSIBLE AGAIN ON WEDNESDAY NIGHT AHEAD OF THE FRONT... AND WITH
ANY SHOWERS AND STORMS ACCOMPANYING THE FRONT (ALONG WITH REDUCED
VISBYS WITH ANY CONVECTION). BREEZY WESTERLY WINDS ARE EXPECTED ON
THURSDAY... WITH WINDS DECREASING LATE ON THURSDAY EVENING AS HIGH
PRESSURE BEGINS TO BUILD INTO THE AREA. VFR CONDITIONS ARE EXPECTED
TO RETURN BY THURSDAY EVENING AND CONTINUE THROUGH AT LEAST SATURDAY
EVENING.
