Severe Thunderstorm Warning 81, NWS Wilmington, NC

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON NC
950 AM EDT FRI JUN 20 2008

.SYNOPSIS...
A WEAK TROF OF LOW PRESSURE WILL PERSIST ACROSS THE EASTERN
CAROLINAS INTO TONIGHT. A FRONTAL BOUNDARY WILL APPROACH FROM THE
WEST LATE SATURDAY AND STALL ACROSS THE AREA SUNDAY THROUGH MONDAY
OF NEXT WEEK BEFORE FINALLY BEING PUSHED OFF THE COAST AND OFFSHORE
ON TUESDAY. HIGH PRESSURE WILL BUILD BACK INTO THE AREA LATE TUESDAY
INTO THURSDAY.

&&

.NEAR TERM /THROUGH TONIGHT/...
AS OF 10 AM FRIDAY...
RAISED POPS TO LOW CHC RANGE TODAY...30S MOST AREAS. CU DEVEL
EARLIER THAN USUAL...INLAND ALONG REMNANT SFC TROUGH AND ALSO EVEN
ALONG SEABREEZE BRUNSWICK HORRY GTOWN. MHX 12Z RAOB CONTINUES TO
SHOW VERY STEEP MID AND LOW LVL LAPSE RATES...10C/KM IN SOME LAYERS.
DEWPOINTS MUCH HIGHER THAN YDY ALTHOUGH RAOB SHOWS PRETTY DECENT
HYDROLAPSE LAPSE RATES. THIS MAY ALLOW DEWPOINTS TO FALL A BIT
INLAND WITH MIXING BUT ALONG THE COAST THE SEABREEZE SHOULD
COMPENSATE. 12Z GUIDANCE MAY ALLOW FOR SOME POP REFINEMENT. TEMPS ET
AL LOOK GOOD.

&&

.SHORT TERM / SATURDAY THROUGH SUNDAY NIGHT/...
AS OF 3 AM FRIDAY...PERSISTENT MID TO UPPER TROUGH CONTINUES TO
HOLD ON OVER THE EASTERN CONUS THROUGH THE SHORT TERM PERIOD. BY SAT
AFTN...MODELS SHOWING A MORE SUBSTANTIAL INCREASE IN MOISTURE IN
AN INCREASING SOUTHERLY FLOW. FAIRLY SIGNIFICANT SHORTWAVE SHOULD
TRACK ACROSS THE CAROLINAS SAT NIGHT. THE COMBINATION OF DEEP
LAYERED MOISTURE PRESENT AND DECENT MID TO UPPER LEVEL SUPPORT
SHOULD PRODUCE FAIRLY DECENT COVERAGE OF SHWRS/TSTMS SAT AFTN INTO
SAT NIGHT AND AGAIN ON SUNDAY. BEST DEEP LAYER MOISTURE AND LIFT
WILL OCCUR LATE SAT THROUGH SUNDAY...BUT INCREASING SW WINDS AT LOW
LEVELS WILL TAKE PLACE ON SUNDAY WITH BETTER JET DYNAMICS. THEREFORE
UNSETTLED WEATHER WILL CONTINUE THROUGH THE ENTIRE SHORT TERM PERIOD
AND BEYOND. PCP WATER VALUES INCREASE TO AROUND 2 INCHES BY SAT AFTN
AND REMAIN THIS HIGH THROUGH THE REMAINDER OF THE SHORT TERM PERIOD.
KEPT WITH HIGH END CHC POPS SAT AFTN AND INCREASED TO LIKELY BY
SUN...BUT WILL PROBABLY END UP IN THE CATEGORICAL RANGE IF MODEL
PERSISTENCE HOLDS THROUGH NEXT RUN.

&&

.LONG TERM /MONDAY THROUGH FRIDAY/...
AS OF 3 AM FRIDAY...LOOKS LIKE UNSETTLED WEATHER WILL CONTINUE
THROUGH THE FIRST HALF OF THE EXTENDED PERIOD AS MID TO UPPER LEVEL
TROUGH HANGS ON ACROSS THE EASTERN CONUS. GFS SHOWS TROUGH DIGGING
ACROSS THE EAST WITH CUTOFF ALMOST FORMING OVER THE MID ATLANTIC
STATES BEFORE FINALLY MOVING OFF THE EAST COAST BY EARLY WEDNESDAY.
MID TO UPPER LEVEL FLOW BECOMES FLATTER ACROSS THE SOUTHEAST WED
INTO THURS WITH RIDGE TRYING TO BUILD IN BY THE END OF THE WEEK AS
HEIGHTS RISE THROUGH MOST OF THE LATTER HALF OF THE EXTENDED. WILL
SEE SOME DRYING IN THE MID TO UPPER LEVELS AS EARLY AS TUES MORNING
BUT MORE SUBSTANTIAL DRYING THROUGH THE COLUMN COMES TUES AFTN INTO
WED AS PCP WATER VALUES DROP TO LESS THAN AN INCH IN A DEEP NW FLOW
AS HIGH PRESSURE BUILDS IN. THEREFORE PCP CHANCES WILL DECREASE
HEADING INTO MID WEEK. LOOKS LIKE DRIEST DAY WILL BE LATE TUES INTO
WED WITH AN INCREASING CHC OF MAINLY SEA BREEZE INITIATED SHOWERS BY
LATER IN THE WEEK. TEMPERATURES SHOULD BE NEAR CLIMATOLOGY EARLY
TRENDING UP A BIT AS THE MID LEVEL RIDGE FLATTENS AND BUILDS EARLY
TO MID WEEK NEXT WEEK.

&&

.AVIATION /12Z FRIDAY THROUGH MONDAY/...
VIA 11-3.9 MICRON SAT IMAGERY...THE OUTLINE OF THE SFC TROF IS
EASILY IDENTIFIABLE AT THE MOMENT. THIS BOUNDARY WILL CONTINUE TO BE
A FOCUS FOR CONVECTION. UPPER IMPULSE CURRENTLY PASSING NORTH OF THE
AREA...IS AIDING IN FIRING ISOLATED CONVECTION ACROSS NORTHEAST
PORTIONS OF NORTH CAROLINA. MODEL SOUNDINGS INDICATE A POSSIBLE CAP
AROUND 600 MB THIS AFTERNOON AND EVENING THAT COULD PUT A DAMPER ON
CONVECTION. AS A RESULT...WILL CONTINUE WITH VICINITY TSRA ACROSS
ALL TERMINALS FOR THE TIME BEING. THE INITIAL S WIND FCST FOR
TERMINALS...ESPECIALLY THE COASTAL TERMINALS...WILL BE ENHANCED BY
THE RESULTANT WIND/SEA BREEZE THIS AFTERNOON AND EARLY EVENING. AREA
TERMINALS WILL LIKELY OBSERVE DIURNAL CU CEILINGS OF 4K FT OR
HIER...WITH COASTAL TERMINALS GOING SCT OR SKC AS THE SEA BREEZE
PROGRESSES SOMEWHAT INLAND.

OUTLOOK SATURDAY THROUGH MONDAY...IFR CONDITIONS OR WORSE FROM
SCATTERED TO POSSIBLY WIDESPREAD CONVECTION LATE SATURDAY INTO
MONDAY. THIS A RESULT OF A STALLED FRONTAL BOUNDARY THAT IS PROGGED
TO LIE ACROSS THE EASTERN CAROLINAS.

&&

.MARINE...
NEAR TERM /THROUGH TONIGHT/...
AS OF 3 AM FRIDAY...BASICALLY 2 WX FEATURES 2 AFFECT THE AREA TODAY
INTO TONIGHT. RATHER WEAK SFC TROF ORIENTED NE-SW ACROSS THE EASTERN
CAROLINAS...AND WEAK HIGH PRESSURE RIDGING ACROSS THE WATERS FROM
JUST OFFSHORE. TO CLARIFY...THE HIGH OFFSHORE IS NOT THE
BERMUDA-TYPE. THE SFC PRESSURE PATTERN TO YIELD A SW TO S WIND
DIRECTION...WITH POSSIBLY A SE WIND DIRECTION ACROSS THE EXTREME
SOUTHERN PORTIONS TONIGHT. THE SFC PRESSURE GRADIENT TO REMAIN
RATHER RELAXED WITH THE SEA BREEZE CIRCULATION TO PROVIDE ADDED WIND
SPEEDS THIS AFTN AND EVENG. LOW LEVEL JET IN THE 950MB LEVEL TO
DEVELOP AROUND SUNSET BUT MAINLY AFFECT LAND AREAS OF THE CAROLINAS
THROUGH 6 AM SATURDAY. SEAS WILL HANG AROUND 2 FT...WITH SOME 3
FOOTERS FROM THE DAILY SEA BREEZE POSSIBLE LATE THIS AFTERNOON AND
EVENING. 1 TO 2 FOOT 8-9 SECOND ESE GROUND SWELL IS BECOMING MORE
EVIDENT WITHIN THE TOTAL SEAS. HOWEVER...ONCE THE SEA BREEZE
CIRCULATION COMMENCES...WIND DRIVEN WAVES DOMINATE TOTAL SEAS.

SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
AS OF 3 AM FRIDAY...PERSISTENT SOUTHERLY FLOW THROUGH SAT WILL
PRODUCE AN INCREASE IN SEAS THROUGH MOST OF THE SHORT TERM PERIOD.
SEAS WILL START OUT IN THE 2 TO 3 FT RANGE...BUT WILL BUILD THROUGH
SAT NIGHT INTO THE 3 TO 5 FT RANGE. SHOULD REMAIN JUST BELOW SCA
CRITERIA THROUGH THE SHORT TERM PERIOD. PEAK IN SEAS SHOULD OCCUR ON
SUN WITH SOUTHERLY WINDS IN THE 10 TO 15 KT RANGE.

LONG TERM /MONDAY THROUGH TUESDAY/...
AS OF 3 AM FRIDAY...BY MON GRADIENT WEAKENS AND SEAS BEGIN TO DROP
OFF BACK DOWN TO 2 TO 3 FT. WESTERLY FLOW DEVELOPS LATER MONDAY INTO
