AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE RALEIGH NC
1030 AM EDT THU JUL 7 2005

.SHORT TERM (REST OF TODAY THROUGH TONIGHT)...
POTENTIAL FOR ACTIVE WEATHER THIS AFTERNOON ACROSS CENTRAL NC AS
SURFACE ANALYSIS DEPICTS WEAK SURFACE BOUNDARY STRETCHING FROM
SOUTHERN PIEDMONT NE INTO SE VA. AIRMASS SOUTH OF BOUNDARY HEATING
UP AND WILL RESULT IN MODERATELY UNSTABLE AIRMASS WITH POTENTIAL FOR
CAPE VALUES 2-3K J/KG. OTHER SEVERE PARAMETERS INDICATE CONDITIONS
FAVORABLE FOR LOW TOP SUPERCELL DEVELOPMENT AS BULK RICHARDSON
NUMBER IN THE MID/UPPER 30S AND LCL HOVERING JUST BELOW 3K FT. IN
ADDITION...SHOULD SEE ENHANCED LOW LEVEL SHEAR THIS AFTERNOON ALONG
AND NORTH OF BOUNDARY AS LOW PRESSURE AREA (ONCE T.S. CINDY) TRAVELS
NE OVER WESTERN SECTIONS THIS AFTERNOON/EARLY EVENING.

TORNADO WATCH OVER THE NRN THIRD OF AREA UNTIL 20Z. WATCH MAY NEED
TO BE EXTENDED FURTHER EAST LATER THIS AFTERNOON.

AS FAR AS SHORT TERM GRIDS...BUMPED MAX TEMPS UP A COUPLE OF
DEGREES...MORE SO SE...AS CLOUD COVER SLOW TO THICKEN/LOWER.

WILL MAINTAIN FFA AS IS FOR NOW AS 12Z U/A ANALYSIS DEPICTS CORE OF
850MB WINDS AIMED AT WESTERN PIEDMONT. PLUS DUAL JET STRUCTURE NOTED
AT 250MB...INCREASING/ENHANCING UPPER LEVEL DIVERGENCE.

.PREVIOUS DISCUSSION...
(ISSUED 640 AM EDT THU JUL 7 2005)

SHORT TERM (REST OF TODAY)...
AN UPDATE HAS BEEN ISSUED BECAUSE OF MORE BREAKS IN THE
CLOUDINESS... APPARENTLY DUE TO SUBSIDENCE TO THE EAST OF CINDY
REMNANTS... WITH EXPECTED INCREASE IN MAXIMUM TEMPERATURES AND DELAY
IN ARRIVAL OF SHOWERS AND TSTMS INTO THE AREA. -RFG

PREVIOUS DISCUSSION...
(ISSUED 220 AM EDT THU JUL 7 2005)

SHORT TERM (TODAY)...
TODAY-TNGT...CINDY REMNANTS CROSS THE AREA WITH THE LOW PRESSURE
CENTER RUNNING UP THE NC APPALACHIANS TODAY AND INTO WRN VA TNGT.
IT SHOULD BE AN ACTIVE WEATHER PERIOD WITH POTENTIAL FOR HEAVY RAIN
AND FLASH FLOODING IN THE WRN THIRD OF THE CWA AND SVR TSTMS IN THE
ERN 2/3RDS...ESPECIALLY SANDHILLS/COASTAL PLAIN FROM AROUND 15Z
THROUGH THIS AFTERNOON.  UPPER DIVERGENCE ON THE NORTH SIDE OF THE
LOW AND A DIFFLUENT 850-300 MB SHEAR VECTOR PATTERN FAVOR HEAVIEST
RAIN TO OUR WEST...BUT A PRE-EXISTING SFC BOUNDARY WILL PROVIDE AN
EASTERN EXTENSION TO THE THREAT OF HEAVY RAIN AND FLASH FLOODING
INTO OUR WESTERN PIEDMONT ZONES UNTIL EARLY TONIGHT.

THE SFC BOUNDARY WILL ALSO ENHANCE LOW LEVEL SHEAR AND HELICITY AND
BOTH GFS AND NAM HAVE SHOWN GOOD CORRELATION WITH CURRENT ACTIVE
CONVECTIVE BAND IN N GA AND MAX MID LEVEL THETA-E LAPSE/ DRY
INTRUSION. MODELS...ESP HIGHER RES NAM...DEPICT 2-3 OF THESE
INTRUSIONS TO THE E OF THE CINDY LOW AND INTO OUR SANDHILLS AND
COASTAL PLAIN ZONES BY THIS AFTERNOON.  THIS LEADS TO AN ENHANCED
RISK OF SUPERCELLS AND ISOLATED TORNADOES IN THE AREA.

HIGHS NEAR 80 IN THE TRIAD TO NEAR 90 IN THE SE TIER.  HIGH DEWPOINT
AIR AND RESIDUAL LOW CLOUDS SHOULD KEEP TEMPERATURES UP WITH MINS OF
69-74 OVERNIGHT.

FRI-FRI NGT...A SURFACE TROUGH AND UPPER SHEAR ZONE REMAIN OVER THE
PIEDMONT IN THE WAKE OF THE CINDY LOW. MODEL SOUNDINGS SHOW SOME
MIDLEVEL SUBSIDENCE WARMING AND DRYING...BUT STILL SUFFICIENT
INSTABILITY AND WITH CONFLUENT SURFACE FLOW...SCATTERED TSTMS SHOULD
RESULT WITH HEATING DURING THE DAY...LINGERING INTO THE EARLY NIGHT
AS THE GFS SHOWS ENHANCED DIVERGENCE AND OMEGA WITH A TRANSIENT
PERTURBATION IN THE NRN STREAM.  HIGHS 87-93. LOWS 69-73.

SAT-SAT NGT...GFS/UKMET/ECMWF SHOW DENNIS TO THE WEST OF CUBA SAT
AND AN UPPER RIDGE BRIDGING FROM THE ATLANTIC TO THE MID MS VLY
ACROSS NC.  A WEAK SFC TROUGH IN THE COASTAL PLAIN MAY RESULT IN
ISOLATED TSTMS...OTRW SUBSIDENCE ALOFT SHOULD HINDER DEEP
CONVECTION. ABOVE NORMAL TEMPERATURES ARE LIKELY.  HIGHS 89-94. LOWS
70-75. -RFG

LONG TERM (SUNDAY THROUGH WEDNESDAY)...
BEYOND SATURDAY AND INTO THE EARLY PART OF THE NEXT WORK WEEK...
CENTRAL NORTH CAROLINA IS IN UPPER RIDGING BETWEEN THE UPPER LOW OFF
THE NORTHEAST COAST AND THE CURRENT FORECAST TRACK OF DENNIS.  HOW
DENNIS EVENTUALLY TRACKS WILL...OF COURSE...HAVE IMPLICATIONS ON THE
LONG TERM CENTRAL NORTH CAROLINA FORECAST.  AT THIS POINT...A
CONSERVATIVE APPROACH IS BEST WITH JUST SLIGHT CHANCES FOR SHOWERS
IN THE GRIDDED FORECASTS TUESDAY AND WEDNESDAY. -DJF

AVIATION...
EARLY PORTIONS OF THE TAFS WILL DEAL WITH A SLOWLY LOWERING
ALTOSTRATUS DECK AS THE REMNANTS OF CINDY LIFT UP THE SPINE OF THE
APPALACHIANS. RAIN SHIELD WILL REACH GSO/INT AREA IN THE MID
MORNING...ALTHOUGH A FEW LIGHT SPITS ARE POSSIBLE EARLIER OUT OF THE
MID DECK. INSTABILITY WILL BE STRONGER IN THE EAST THIS AFTERNOON
DUE TO MID LEVEL DRY AIR AND FILTERED INSOLATION WHICH WILL ALLOW
TEMPS TO HIT THE UPPER 80S. CONDITIONS WILL REMAIN VFR OUTSIDE OF
HEAVIER SHOWERS TODAY...AND LOWER TO MVFR AFTER 00Z. WINDS WILL BE
FROM THE EASTERLY QUADRANT TODAY...NORTHEAST SHIFTING TO SOUTHEAST
IN THE AFTERNOON...AT SPEEDS 10 KNOTS OR BELOW AS THE LOW FILLS.
