AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON NC
232 PM EDT THU JUL 5 2012

.SYNOPSIS...
BERMUDA HIGH PRESSURE OFFSHORE AND THE PIEDMONT TROUGH INLAND WILL
PREVAIL THROUGH MUCH OF THE FORECAST PERIOD...BRINGING HOT AND HUMID
CONDITIONS WITH ISOLATED THUNDERSTORMS EACH AFTERNOON AND EVENING.
AN UPPER RIDGE OVER THE AREA WILL SLOWLY WEAKEN NEXT WEEK...BRINGING
DAYTIME TEMPERATURES CLOSER TO NORMAL FOR JULY.

&&

.NEAR TERM /THROUGH TONIGHT/...
AS OF 130 PM THURSDAY...HEAT ADVISORY CONTINUES WITH HEAT AND
HUMIDITY COMBINING TO PRODUCE HEAT INDEX VALUES UP TO 107 DEGREES.
WITH STRONG UPPER RIDGE TO OUR WEST THE H5 HEIGHTS REMAIN UP
AROUND 590 DEM AND 850 TEMPS WILL BE JUST OVER 20C. THE WESTERLY
LOW LEVEL FLOW ALSO HELPING TO PRODUCE EXCESSIVE HEAT ACROSS AREA
WHILE SW FLOW OF MOIST AIR HELPS TO KEEP DEWPOINT TEMPS UP AROUND
70. THE ACTUAL TEMPS WILL REACH BETWEEN 95 AND 100 THIS AFTERNOON.
THE HEAT INDEX SHOULD HOLD JUST BELOW 105 DEG ALONG A SLIVER OF
COASTAL NORTH CAROLINA DUE TO THE SEABREEZE CIRCULATION. A HEAT
ADVISORY WILL BE IN EFFECT FOR MOST OF THE AREA UNTIL 9 PM THIS
EVENING.

LOCAL AREA REMAINS ON EASTERN PERIPHERY OF THE STRONG RIDGE TO
THE WEST. THIS WILL ALLOW ANY PERTURBATIONS AND ASSOCIATED ORGANIZED
CONVECTION TOPPING THE RIDGE TO MAKE A RUN FOR THE CAROLINAS. ANOTHER
MORE POTENT PERTURBATION WILL RIDE DOWN FROM THE NORTH THROUGH
TONIGHT BUT MOST OF THE ASSOCIATED ENERGY WILL REMAIN WEST OF
LOCAL AREA WITH COASTAL SECTIONS REMAINING IN SUBSIDENCE THROUGH
MUCH OF THE DAY. THE SEABREEZE AND PIEDMONT TROUGH WILL PROVIDE
SOME ADDED LOW LEVEL FORCING AND CONVERGENCE...ALLOWING ISOLATED
CONVECTION TO POP WITH STRONG HEATING. THE HRRR SHOWED CONVECTION
FLARING ALONG SEA BREEZE BOUNDARY THROUGH THIS LATE THIS
AFTERNOON. GIVEN THE MID LEVEL DRY AIR AND SUBSIDENCE WILL KEEP
STORMS ISOLATED THROUGH THIS EVENING. THE LOW LEVEL FLOW WILL BACK
TO A MORE NORTHERLY DIRECTION PRODUCING A NORTHERLY STEERING FLOW. THEREFORE
ANY SHOWERS THAT DEVELOP WILL MOVE VERY SLOWLY SOUTH.

LATEST NAM SHOWS SHORTWAVE RIDING DOWN THROUGH WESTERN CAROLINAS
COULD AFFECT MAINLY WESTERN COUNTIES OF LOCAL CWA LATER THIS
EVENING INTO OVERNIGHT HOURS. WILL KEEP SLIGHT CHC POPS IN
FORECAST OVERNIGHT.

TEMPS WILL BE SLOW TO DROP TONIGHT WITH NOCTURNAL SOUTHWEST
JET. NAM WINDS JUST ABOVE THE SURFACE WILL BE UP NEAR 25K KTS.
EXPECT ATMOSPHERE TO DECOUPLE ALLOWING SURFACE WINDS TO DROP BUT
THIS SHOULD HAVE SOME AFFECT ON THE TEMPS OVERNIGHT. OVERALL WARM
AND HUMID AIR MASS IN PLACE WITH TEMPS HOLDING ABOVE 80 THROUGH
MOST OF THE EVENING AND FALLING INTO THE UPPER 70S MOST PLACES BY
DAYBREAK.

&&

.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
AS OF 3 AM THURSDAY...DEEP DRY AIR AND WEAK SUBSIDENCE IN PLACE
UNDER EASTERN EXTENSION OF PLAINS 5H RIDGE WILL MINIMIZE PRECIP
CHANCES DURING THE PERIOD. FRI LOOKS THE BETTER OF THE 2 DAYS AS FAR
AS CONVECTION GOES...ESPECIALLY ALONG THE PIEDMONT TROUGH AND SEA
BREEZE. THERE IS PLENTY OF INSTABILITY...MLCAPE FRI AFTERNOON
APPROACHES 3K J/KG AND LAPSE RATES AROUND -8 C/KM...BUT THE
PRESENCE OF DEEP DRY AIR WILL LIKELY KEEP COVERAGE LIMITED TO
ISOLATED AT BEST. MOS NUMBERS HAVE BEEN TRENDING DOWN AND GIVEN THE
LACK OF CONVECTION THE PAST FEW DAYS SEE NO REASON TO CARRY A POP
HIGHER THAN SLIGHT CHANCE FRI AFTERNOON. SAT WILL BE MUCH THE SAME
AS FRI...THOUGH THE COLUMN WILL BE A LITTLE DRIER. PRECIPITABLE
WATER VALUES DROP FROM 1.7 FRI TO 1.5 SAT. ALSO WARMING ALOFT...AS
SUBSIDENCE STRENGTHENS...WILL LEAD TO A DECREASE IN OVERALL
INSTABILITY. CAPE VALUES DROP BELOW 2K J/KG ACROSS MUCH OF THE AREA.
STILL CARRY A SLIGHT CHANCE POP FOR SAT AFTERNOON...WITH BOTH THE
SEA BREEZE AND THE PIEDMONT TROUGH POSSIBLE TRIGGER MECHANISMS...BUT
NOW HAVE A SHORTER PERIOD OF LOW SLIGHT CHANCE POP SAT AFTERNOON.

LOW LEVEL WEST TO SOUTHWEST FLOW UNDER NORTH TO NORTHEAST FLOW ALOFT
WILL HELP KEEP THE SEA BREEZE PINNED CLOSER TO THE COAST. 850 TEMPS
IN THE LOWER 20C RANGE COMBINED WITH LIMITED INLAND PENETRATION OF
SEA BREEZE...ESPECIALLY SAT...SHOULD SEE WIDESPREAD HIGHS IN THE MID
TO UPPER 90S WITH TRIPLE DIGITS POSSIBLE. LOWS WILL BE IN THE MID
70S. HEAT INDEX VALUES ARE FORECAST TO BE 105-109 DURING EACH
AFTERNOON. THIS WOULD REQUIRING HEAT ADVISORIES FOR BOTH DAYS.

&&

.LONG TERM /SUNDAY THROUGH THURSDAY/...
AS OF 3 AM THURSDAY...MEDIUM RANGE GUIDANCE SHOWS THE EASTERN
EXTENSION OF THE 5H RIDGE BREAKING DOWN LATE SUN. THIS PROBABLY
HAPPENS TO LATE FOR ANY SIGNIFICANT PRECIP FOR THE END OF THE
WEEKEND...HENCE SLIGHT CHANCE...BUT IT DOES BRING ABOUT A CHANGE TO
THE PATTERN ALOFT EARLY NEXT WEEK. A SERIES OF SHORTWAVE TROUGHS
WILL HELP DRIVE 5H TROUGH AXIS FARTHER AND FARTHER SOUTH. 00Z GFS
HAS COME IN FASTER THAN THE CANADIAN OR ECMWF SOLUTIONS...POSSIBLY
DUE TO ITS PROPENSITY TO OVER AMPLIFY SHORTWAVES. THUS FAVORED THE
SLOWER SOUTHWARD PUSH OF THE 5H TROUGH SEEN IN THE ECMWF/CANADIAN
SOLUTIONS. ACCOMPANYING THE 5H TROUGH AS IT HEADS SOUTH IS A COLD
FRONT AND DEEP MOISTURE. INITIALLY DEEPER MOISTURE IS MAINLY
ASSOCIATED WITH THE SURFACE BOUNDARY. ONCE THE 5H TROUGH SETS UP
WEST OF THE AREA...LATER TUE...DEEP SOUTHWEST FLOW WILL TAP INTO
GULF MOISTURE.  PRECIPITABLE WATER VALUES JUMP FROM 1.8 TO OVER 2
INCHES LATE TUE AND WED. BASED ON THE DELAYED TIMING HAVE TRIMMED
BACK THE MON POP TO 40 WITH 40 TO 50 FOR TUE AND 40 FOR WED. ANY
PASSING SHORTWAVES WOULD LEAD TO AN INCREASE IN PRECIP COVERAGE AND
INTENSITY...BUT TIMING THESE FEATURES SEVERAL DAYS OUT IS NOT
FEASIBLE. TEMPERATURES ABOVE CLIMO SUN WITH A GRADUAL DOWNWARD TREND
IN BOTH HIGHS AND LOWS THROUGH THE PERIOD. HIGHS END UP BELOW CLIMO
TUE/WED WITH LOWS FALLING BACK TO CLIMO AT THE END OF THE PERIOD.

&&

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
AS OF 18Z...MOST OF THE MODELS ARE NOT TOO ENTHUSED ABOUT CONVECTION
THIS AFTERNOON...THE EXCEPTION BEING THE NSSL WRF SHOWING A COMPLEX OF
STORMS DROPPING SOUTHEAST INTO THE REGION THIS AFTERNOON. FEEL THIS
MAY BE A BIT OVERDONE...WENT WITH VCTS IN THE TAFS. COULD NOT RULE
OUT A GOOD THUNDERSTORM...BEST CHANCE AT THE INLAND TERMINALS.
CONTINUED SOUTHWEST FLOW...A BIT GUSTY ALONG THE COAST.
TONIGHT...ISOLATED CONVECTION WILL BE WANING...WITH MID AND HIGH
CLOUD DEBRIS. CHANCE OF BRIEF MVFR FOG AROUND SUNRISE. LIGHT
SOUTHWEST FLOW...INCREASING WITH DAYTIME HEATING AND SUBSEQUENT
MIXING FRIDAY MORNING.

EXTENDED OUTLOOK...A CHANCE OF ISOLATED THUNDERSTORMS THROUGH THE
WEEKEND...POSSIBLY BECOMING MORE NUMEROUS MONDAY AND TUESDAY.
OTHERWISE EXPECT VFR.

&&

.MARINE...
NEAR TERM /THROUGH TONIGHT/...
AS OF 130 PM THURSDAY...SOUTHWEST FLOW BETWEEN BERMUDA HIGH AND
PIEDMONT TROUGH OVER INLAND CAROLINAS WILL CONTINUE THROUGH
TONIGHT. NAM CONTINUES TO SHOW NOCTURNAL JET UP TO 25 KTS OVER THE
COASTAL WATERS OVERNIGHT. THE 975 MB WINDS ARE COMING IN CLOSE TO
35 KTS. OVERALL WILL SEE ENHANCED SEA BREEZE FLOW DIMINISH NEAR
SHORE THROUGH THIS EVENING BUT THIS JET ACROSS THE WATERS WILL
KEEP WINDS UP OVERNIGHT. SOUTHWEST WINDS 15 TO 20 KTS WILL KEEP
SEAS AROUND 3 TO 4 FT ACROSS MUCH OF THE WATERS THROUGH TONIGHT AND
COULD SPIKE AS HIGH AS 5 FT IN OUTERMOST WATERS.

SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
AS OF 3 AM THURSDAY...BERMUDA HIGH AND PIEDMONT TROUGH WILL PRODUCE
THE TYPICAL SUMMER TIME SOUTHWEST FLOW OVER THE WATERS. SPEEDS WILL
RUN 10 TO 15 KT THROUGH THE PERIOD WITH A MARGINAL INCREASE EACH
AFTERNOON AS SEA BREEZE DEVELOPS AND PIEDMONT TROUGH BECOMES MORE
DEFINED. SEAS 2 TO 4 FT THROUGH THE PERIOD...A MIX OF THE DOMINANT
SOUTH TO SOUTHWEST WIND WAVE AND WEAK SOUTHEAST SWELL.

LONG TERM /SUNDAY THROUGH MONDAY/...
AS OF 3 AM THURSDAY...SOUTHWEST FLOW CONTINUES WITH WATERS BETWEEN
BERMUDA HIGH AND PIEDMONT TROUGH. GRADIENT BECOMES PINCHED SUN WITH
WINDS A SOLID 15 TO 20 KT. GRADIENT RELAXES SLIGHTLY FOR MON BUT
SPEEDS WILL STAY A SOLID 15 KT. WILL ONCE AGAIN SEE A SLIGHT
INCREASE IN SPEEDS EACH AFTERNOON AS SEA BREEZE DEVELOPS AND
PIEDMONT TROUGH BECOMES MORE DEFINED. INCREASED SPEEDS AND PROLONGED
PERIOD OF SOUTHWEST FETCH WILL RESULT IN A SLIGHT BUMP IN SPEEDS
DURING THE PERIOD. SEAS 3 TO 4 FT BUILD TO 3 TO 5 FT LATE EACH
DAY...MAINLY MADE UP OF SHORT PERIOD SOUTHWEST WIND WAVE. SCEC WILL
BE POSSIBLE EACH AFTERNOON.
