AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEWPORT/MOREHEAD CITY NC
406 PM EDT SUN JUN 19 2011

.SYNOPSIS...
A COLD FRONT WILL SINK S ACROSS THE REGION TONIGHT THEN WEAKEN AND
SLOWLY RETURN N AS A WARM FRONT ON MON. A TROUGH WILL DEVELOP
INLAND WITH WEAK HIGH PRES OFFSHORE TUES THRU THURS.

&&

.NEAR TERM /THROUGH TONIGHT/...
AS OF 405 PM SUNDAY...SMALL CLUSTER OF SHOWERS AND TSTMS HAS
WORKED FROM DUPLIN COUNTY TO OFF THE CARTERET COUNTY COAST OVER
THE PAST HOUR AND A HALF. ADDITIONAL SHOWERS HAVE REDEVELOPED IN
THIS SAME AREA IN AXIS OF HIGHER CAPES. REMAINDER OF ACTIVITY IS
TO THE SOUTH OVER EXTREME SOUTHEASTERN NORTH CAROLINA AND
NORTHEAST SOUTH CAROLINA IN AREA OF HIGHER CAPE AND MORE FAVORABLE LI
VALUES. ONE FACTOR IN KEEPING WIDESPREAD CONVECTIVE INITIATION
DOWN OVER OUR CWA THUS FAR IS WESTERLY SURFACE FLOW AND A DEEP
WESTERLY LAYER WITH RELATIVELY LOW DEWPOINTS IN THE LOWER AND
MIDDLE 60S OVER INLAND AREAS. NAM...HRR AND NSSL WRF ARE SHOW
INCREASED ACTIVITY LATER THIS EVENING THRU AFTER MIDNIGHT AS
REMNANTS OF CONVECTIVE COMPLEX OVER THE MOUNTAINS OF NC WORKS EAST
INTO A MORE UNSTABLE AIRMASS. HAVE HIGH CHANCE 40 TO 50 PCT POPS
OVER MOST OF THE CWA THRU THE OVERNIGHT HOURS...TAPERING TO LOW
CHC ALONG THE OUTER BANKS/SOUTHERN COAST COUNTIES. STILL CANNOT
RULE OUT AN ISOLATED STRONG TO SEVERE STORM OR TWO GIVEN HIGH
VALUES OF WINDEX (58 KNOTS) AND RESPECTABLE SHEAR VALUES. ANOTHER
WARM MUGGY NIGHT ON TAP WITH MINS IN THE 72 TO 79 DEGREE RANGE.

&&

.SHORT TERM /MONDAY/...
AS OF 405 PM SUNDAY...FRONTAL BOUNDARY TO MOVE TO NEAR THE
CENTRAL SECTIONS OF OUR CWA BY EARLY MONDAY BEFORE DISSIPATING.
MEANWHILE BOTH THE GFS AND NAM BRING WAVE OF LOW PRESSURE ALONG
THE BOUNDARY JUST NORTH OF THE CWA MONDAY AFTERNOON AND OFFSHORE
BY LATE IN THE DAY. THIS WILL SERVE TO INCREASE WINDS...ESPECIALLY
OVER THE NORTHERN SECTIONS OF THE CWA AND WILL LEAD TO TEMPS THAT
ARE A FEW DEGREES COOLER THAN TODAY. GFS SHOWS EASTERN NORTH
CAROLINA IN AN AREA OF WEAK NEGATIVE VORTICITY ADVECTION AND
SUBSIDENCE WHILE THE NAM12 DOES SHOW AND MID-LEVEL VORTMAX
SWINGING ACROSS THE CENTRAL CWA DURING THE AFTERNOON. DEEP
NORTHWESTERLY FLOW PER FORECAST SOUNDINGS SHOULD KEEP THE SEA
BREEZE CLOSER TO THE COAST AND THINK CONVECTION CHANCES WILL BE
MINIMAL WITH ONLY 20 PCT POPS FORECASTED AT THIS TIME.

&&

.LONG TERM /MONDAY NIGHT THROUGH SUNDAY/...
AS OF 3 PM SUN...EXITING SFC LOW PRES WILL BRING DRIER AND COOLER AIR
INTO E NC FOR MON NIGHT AS WINDS TURN NORTHERLY. 850MB THERMAL
GRADIENT WILL BE LEFT BEHIND ACROSS WRN CWA AND COMBINED WEAK
SHORTWAVE ACTIVITY IN NW FLOW MAY BE ENOUGH FOR SOME ELEVATED
CONVECTION THROUGH MON NIGHT. SFC HIGH QUICKLY TRANSLATES EASTWARD
TUE WITH RETURN FLOW ENSUING. SMALL CHANCE FOR CONVECTION ONCE
AGAIN MAINLY INLAND COUNTIES DUE TO SEA BREEZE PROPAGATION IN
COMBO WITH MORE POTENTIAL NW FLOW SHORTWAVE ACTIVITY.

FCST BECOMES MORE CERTAIN FOR TUE NIGHT THROUGH THUR...AS UPR
RIDGE BUILDS AND 850 MB TEMPS SOAR TO ABOVE 20C. WED APPEARS TO BE
THE WARMEST DAY IN THE EXTENDED PERIOD WITH INLAND LOCALES
IN THE MID TO UPPER 90S. IN ADDITION...RH VALUES WILL BE ON THE
INC AS DEEP SOUTHERLY FLOW IN PROGRESS. HEAT INDICES WILL NEAR 105
FOR MANY AREAS AWAY FROM THE COAST.

MED/LONG RANGE MODELS IN DECENT AGREEMENT ON SYNOPTIC PATTERN FOR
THUR/FRI. LARGE UPR TROUGH WILL SWING THROUGH THE GREAT LAKES
REGION...PUSHING A SFC FRONT SOUTH THROUGH THE OHIO VALLEY/MID
ATLANTIC REGION. FRONT WILL WEAKEN BY THE TIME IT REACHES THE NC
COAST...THOUGH MAY BE ENOUGH TO GENERATE A FEW STORMS IN
CONJUNCTION WITH SEA BREEZE. LEFT SLIGHT CHANCE POPS IN FOR THIS
PERIOD. BOUNDARY LOOKS TO STALL OUT FOR THE WEEKEND WITH WITH
SMALL CHANCES FOR THUNDER CONTINUING.

&&

.AVIATION /19Z SUNDAY THROUGH FRIDAY/...
AS OF 405 PM SUNDAY...GENERALLY ANTICIPATE VFR CONDITIONS THRU
THE NEXT 24 HOURS. COULD HAVE BRIEF REDUCTIONS IN CEILINGS/VSBY
LATER TONIGHT IN ANY STORMS THAT DO DEVELOP...AND DURING THE
MORNING HOURS MONDAY IN AREAS THAT RECEIVE PRECIP.

/LONG TERM MON NIGHT THROUGH FRI/...
AS OF 320 PM SUN...MAINLY VFR CONDITIONS THOUGH COULD BE SOME
ISOLATED THUNDERSTORMS MON NIGHT AND TUE. DRY CONDITIONS EXPECTED
WED AND THUR BEFORE A WEAK COLD FRONT MOVES IN FOR FRI THROUGH THE
WEEKEND BRINGING ANOTHER SMALL CHANCE FOR THUNDERSTORMS.

&&

.MARINE...
/SHORT TERM TONIGHT AND MONDAY/...
AS OF 405 PM SUNDAY...HAVE ISSUED A SMALL CRAFT ADVISORY FOR ALL
COASTAL WATERS. AREAS SOUTH OF HATTERAS WILL BEGIN LATER TONIGHT
AS SOUTHWEST WINDS INCREASE THEN WILL SHIFT TO THE NORTHERN WATERS
MONDAY AS SURFACE LOW PRESSURE MOVES JUST NORTH OF THE AREA AND
WINDS/SEAS INCREASE ON THE BACK SIDE OF THE LOW MONDAY AFTERNOON
AND EVENING. HAVE TRENDED TOWARD WAVEWATCH AS LOCAL SWAN HAS
TRENDED A TAD HIGH THE PAST FEW DAYS. SEAS SHOULD PEAK AT 6 TO 8
FEET BY LATE MONDAY INTO MONDAY NIGHT.

/LONG TERM MON NIGHT THROUGH FRI/...
AS OF 330 PM SUN...SFC LOW OFFSHORE WILL CONTINUE PULLING AWAY
FROM THE WATERS. NW WINDS WILL VEER N AND GRADUALLY DIMINISH
THROUGH MON EVENING. HOWEVER...SEAS WILL BE SLOWER TO SUBSIDE AND
SCA CONDITIONS WILL LINGER INTO EARLY TUE MORNING...ESP ACROSS THE
CENTRAL AND NORTHERN WATERS.

HIGH PRES WILL TRANSLATE EASTWARD AND OFF THE COAST BY TUE...WITH
WINDS VEERING SE TUE AFTERNOON AS RETURN FLOW ENSUES. WINDS VEER
FURTHER TO SW LATE TUE NIGHT AND INC TO THE 10 TO 15 KT RANGE. THE
SW FLOW WILL CONTINUE THROUGH THE REST OF THE WEEK IN THIS
RANGE...THOUGH AS UPR TROUGH AND COLD FRONT APPROACH ON THUR...
SCA CONDITIONS MAY DEVELOP ACROSS PORTIONS OF THE WATERS FOR THUR
NIGHT.
