Severe Thunderstorm Warning 117, NWS Wilmington, NC

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON NC
1011 AM EST TUE NOV 12 2002

COLD FRONT OVER WESTERN SECTIONS OF THE CAROLINAS TO MOVE EAST TODAY
AS AN UPPER TROUGH GIVES IT A PUSH.  WE WILL LIKELY SEE THE FRONT
JUMP INTO A TROUGH IN THE COASTAL PLAIN THIS AFTERNOON AFTER LOW
PRESSURE OVER SOUTH CAROLINA MOVES TO THE NORTH.  EXPECT SHOWERS AND
STORMS TO CONTINUE THIS AFTERNOON.  DUE TO LIMITED INSTABILITY IN
PARCELS BELOW H9 OR SO...SEVERE WEATHER POTENTIAL LOOKS LIMITED.
HOWEVER...ISOLATED SEVERE IS NOT TOTALLY OUT OF THE QUESTION OVER
THE COASTAL COUNTIES WHERE A LITTLE INSOLATION AND HIGHER SURFACE
DEWPOINTS COULD ALLOW SURFACE BASED CONVECTION TO INITIATE.
TEMPERATURES WOULD NEED TO GET TO THE HIGH END OF CURRENT FORECAST
RANGES FOR THIS TO OCCUR.

ALL IN ALL...THE CURRENT PUBLIC FORECAST LOOKS TO BE IN GOOD SHAPE.
NO UPDATE PLANNED AT THIS TIME.

CWF:  HINT OF SFC LOW OVER SC...MAINTAINING SE GRADIENT ACROSS MY
AREA THIS MORNING.  TWO AREAS OF STRONG TSRA TO AFFECT THE WATERS
THRU LATE MORNING...ADDRESSED IN MWSILM.

WILL INITIALIZE SE TO S AND HIT THE CONVECTION A LITTLE HARDER.  NOT
SURE WE WILL REACH SCA WINDS IN SW FLOW THIS AFTERNOON...BUT WITH
ADVISORY ALREADY FLYING WILL NOT TAKE IT DOWN.  SEAS RUNNING 6 FT AT
FPSN7 ANYWAY.  NO SIG CHANGES BEYOND THE FIRST PERIOD.

.ILM...
NC...SMALL CRAFT ADVISORY AMZ250-252.
SC...SMALL CRAFT ADVISORY AMZ254-256.

---------------------PREVIOUS DISCUSSION 325 AM----------------------
SEVERE THUNDERSTORMS ACROSS COASTAL WATERS AT TIME.

WEAK WAVE OF LOW PRESSURE OVER NORTHEAST GULF OF MEXICO WILL BE
ENERGIZED BY JET MAXIMA APPROACHING FROM NORTHWEST. THIS WAVE WILL
MOVE NORTHEAST ALONG STALLED FRONTAL BOUNDARY ACROSS WESTERN
CAROLINAS.

AREA IS UNDER SLIGHT RISK FOR SEVERE THUNDERSTORMS TODAY.
INSTABILITY WILL BE ON THE INCREASE TODAY WITH APPROACH OF LOW
PRESSURE. MID LEVEL WINDS S TO SW 60+ KT. H8 WINDS MAX OUT AT 35 TO
40 KT.

WIND PROFILE FAIRLY UNI-DIRECTIONAL AND SO MAIN SEVERE THREAT
SHOULD BE DAMAGING WINDS LATE AFTERNOON AND THIS EVENING.
HOWEVER...VOD CONSIDERABLY LOWER THAN YESTERDAY AND SO MAY SEE SOME
HAILERS WITH LOWER WET BULB ZEROS.

HEAVY RAIN POTENTIAL WITH PRECIPITABLE WATERS 1.5+ INCHES.
CONVECTION WILL BE MOVING ALONG AT 35+ KT TODAY BUT MAY SEE SOME
TRAINING. HEAVIEST RAIN LIKELY TO LIFT TO NORTHEAST...BUT WELL WEST
OF AREA THIS AFTERNOON AND EVENING.

AS LOW PRESSURE MOVES BY...COLD FRONT WILL FINALLY MOVE ACROSS AREA
AND OFF THE COAST 02Z TO 05Z. STILL...UPPER TROUGH WILL NOT CLEAR
COAST UNTIL LATE ON WEDNESDAY AND SO INCLUDED THREAT FOR SHOWERS ON
WEDNESDAY.

HIGH PRESSURE AND SOME WEDGING EVIDENT LATE IN WEEK AND EARLY
WEEKEND. GFS INDICATING THE DEVELOPMENT OF A COASTAL TROUGH. ANOTHER
COLD FRONT SWEEPS OFF THE COAST SATURDAY NIGHT OR SUNDAY AS AN
AREA OF LOW PRESSURE DEVELOPS OFF THE SOUTHEAST ATLANTIC COAST AND
STRENGTHENS AS IT MOVES NORTH (PER GFS). HAVE ADDED POPS FOR THE
WEEKEND.

MARINE: MARINE: WILL CONTINUE SCA ALL WATERS. ETA THE MODEL OF
CHOICE WITH REGARDS TO COLD FRONT PASSAGE. WINDS EXPECTED TO PICK UP
TO SCA LEVELS BY AFTERNOON AS THE 35-40 KT LOW LEVEL JET CROSSES THE
REGION. SHOWERS/TSTMS WILL ALSO AID IN BRINGING SOME OF THESE HIGHER
WINDS DOWN TO THE SFC. WILL VEER WINDS NW BEHIND THE FRONT
TONIGHT...AND CONTINUE 20-25 KT WINDS THROUGH WED NIGHT WITH STRONG
CAA OVER THE WATERS.
