Area forecast discussion, Jun 17, 7:53 PM EDT, 1 hour 21 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON NC
753 PM EDT WED JUN 17 2015

.SYNOPSIS...
HIGH HEAT AND HUMIDITY WILL PERSIST THROUGH THE WEEKEND AND INTO
NEXT WEEK AS WELL. A HEAT ADVISORY REMAINS IS IN EFFECT FOR ALL
BUT THE BEACHES TODAY. SHOWERS AND THUNDERSTORMS WILL BE ON THE
INCREASE...BECOMING SCATTERED FRIDAY INTO THE WEEKEND. BERMUDA
HIGH PRESSURE WILL REMAIN IN PLACE OFFSHORE...WHILE THE PIEDMONT
TROUGH BECOMES MORE ESTABLISHED IN THE DAYS AHEAD.

&&

.NEAR TERM /THROUGH TONIGHT/...
AS OF 700 PM WEDNESDAY...ANOTHER HOT AND HUMID DAY COMING TO AN
END...BUT A STEAMY NIGHT IS ONCE AGAIN IN THE FORECAST.

SEVERAL FEATURES AT PLAY THIS EVENING TO PRODUCE THE LOCAL WEATHER.
MASSIVE UPPER RIDGE REMAINS ACROSS THE SOUTHEAST...ALTHOUGH IT HAS
BEEN SHUNTED AT LEAST SUBTLY TO THE SOUTH BY A COLD/STATIONARY
FRONT CURRENTLY DRAPED FROM THE OUTER BANKS NW THROUGH WV AND INTO
THE OH VLY. A WEAK SURFACE TROUGH REMAINS ACROSS THE SW TIER OF THE
ILM CWA...WHILE THE SEA BREEZE BOUNDARY ONCE AGAIN PUSHES TOWARDS I-
95...QUITE RARE TO HAVE IT THIS FAR WEST BY MID-JUNE...AND IS A
CLEAR SIGN OF THE IMPRESSIVENESS OF THE LOCAL AIRMASS.

SEA BREEZE BOUNDARY AS WELL AS THE SURFACE TROUGH WILL CONTINUE TO
BE A FOCUS FOR SCATTERED TSTMS FOR THE NEXT FEW HOURS...BUT WITHOUT
ANY SIGNIFICANT UPPER SUPPORT EXPECT ACTIVITY TO WANE WITH LOSS OF
DIURNAL HEATING. THE SURFACE FRONT SHOULD RETREAT TO THE NE TONIGHT
AS THE RIDGE BEGINS TO RE-ASSERT ITSELF LATE...AND THIS WILL ALLOW
WINDS TO ONCE AGAIN BECOME PREDOMINANTLY SW...AND KEEP MIN TEMPS
WELL ABOVE NORMAL. HAVE SIDED MORE WITH THE WARMER MAV NUMBERS...AND
LOWS TONIGHT WILL RANGE FROM 75-80...WARMEST ON THE BRUNSWICK COUNTY
BEACHES.

HIGH-RES GUIDANCE HAS BEEN BACK-AND-FORTH BRINGING A CLUSTER OF
TSTMS FROM VA DOWN ACROSS THE NORTHERN ZONES OF THE ILM CWA. WHILE
THIS SETUP IS FAVORABLE FOR SUCH DEVELOPMENT...ANY CONVECTION SHOULD
FOLLOW THE RETREATING FRONT...AND EXPECT BEST TSTM CHANCES OVERNIGHT
TO REMAIN WELL NE OF THE CWA...AND HAVE DROPPED POP TO SILENT ACROSS
THE AREA AFTER MIDNIGHT.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
AS OF 300 PM WEDNESDAY...THOUGH WE WILL SEE A SLIGHT RELIEF IN
HEAT IN THE SHORT TERM...OVERALL HOT AND HUMID WEATHER WILL
CONTINUE WITH A GRADUAL INCREASING CHANCE FOR ISOLATED TO
SCATTERED SHOWERS AND THUNDERSTORMS THURSDAY AND FRIDAY.

RIDGE OF HIGH PRESSURE WILL IN PLACE ACROSS THE SOUTHEAST ON
THURSDAY...SHIFTING JUST SOUTH OF OUR AREA FRIDAY INTO SATURDAY.
OUR MAIN FOCUS THROUGH THE FORECAST PERIOD WILL BE ON THE REMNANTS
OF TROPICAL STORM BILL ROUNDING THE OUTSKIRTS OF THE HIGH UP INTO
THE OHIO VALLEY AND A SHORT WAVE TROUGH SETTING UP CAMP ACROSS
NORTH CAROLINA...DEEPENING INTO A SFC LOW ON FRIDAY. THIS FEATURE
ALONG WITH THE SEABREEZE...INCREASING MOISTURE AND INCREASING
INSTABILITY WILL ALLOW FOR ISOLATED SHOWERS AND THUNDERSTORMS ON
THURSDAY...BECOMING SCATTERED ON FRIDAY. SOUTHWEST FLOW WILL
PERSIST WITH FLOW ALOFT BECOMING MORE WESTERLY.

LATEST FORECAST TRENDS CONTINUE TO INDICATE POTENTIAL FOR HEAT
ADVISORY ON THURSDAY...WITH APPARENT TEMPERATURES 103 TO 105. AS FOR
FRIDAY...EXPECT CONDITIONS TO FALL JUST BELOW HEAT ADVISORY
CRITERIA...THOUGH HEAT INDICES WILL STILL BE IN UPPER 90S ALONG THE
IMMEDIATE COAST TO LOWER 100S INLAND.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
AS OF 300 PM WEDNESDAY...A WEAK MID LEVEL TROUGH...THE REMNANTS OF
TROPICAL STORM BILL WILL MOVE ACROSS THE REGION SATURDAY AND
SUNDAY LEAVING A WEAK NORTHWEST FLOW IN ITS WAKE. BY THE END OF
THE PERIOD MID LEVEL HIGH PRESSURE BUILDS BACK IN WITH THE
CENTER...A LITTLE WEST OF THIS WEEKS POSITION CLOSER TO TENNESSEE
AND MISSISSIPPI. TEMPERATURES WILL CONTINUE TO BE WELL ABOVE
NORMAL AND INCREASING MORESO TOWARD THE END OF THE PERIOD. THE
LATEST MEX NUMBERS ARE QUITE DAUNTING WITH THREE STRAIGHT DAYS OF
TRIPLE DIGITS IN LUMBERTON AND FLORENCE. COASTAL AREAS ARE IN THE
MIDDLE TO UPPER 90S. POPS...BEYOND GOOD CHANCE SATURDAY ARE AROUND
OR BELOW CLIMATOLOGY MAINLY ON A DIURNAL BASIS THE REMAINDER OF
THE PERIOD. WITH THE POSITION OF THE MID LEVEL RIDGE A LITTLE
FURTHER WEST THE RING OF FIRE OR MESOSCALE CONVECTIVE SYSTEMS
COULD BECOME MORE OF A PLAYER FOR THE AREA. GUIDANCE NOT REALLY
SHOWING THAT AT THIS POINT HOWEVER.

&&

.AVIATION /00Z THURSDAY THROUGH MONDAY/...
AS OF 00Z...HIGH CONFIDENCE OF VFR THIS TAF VALID PERIOD. ISOLD
SHRA/TSRA THIS EVNG SHOULD DISSIPATE OVER THE NEXT FEW HOURS...BUT
ACTIVITY COULD CONTINUE N OF KLBT/KILM OVERNIGHT. THIS ACTIVITY
WILL PRODUCE OUTFLOW BOUNDARYS...SOME OF WHICH COULD MOVE S INTO
THE NORTHERN TERMINALS POSSIBLY PRODUCING ISOLD SHRA IN THE
OVERNIGHT HOURS BUT CONFIDENCE IS LOW. OVERALL EXPECT SE-S WINDS
THIS EVENING TO BECOME SW OVERNIGHT EXCEPT LGT/VRBL AT KLBT. BY
DAYBREAK EXPECT SW-W WINDS. WINDS WILL BE SW-W BECOMING S-SSW AT
THE COASTAL TERMINALS AND SW AT THE INLAND TERMINALS BY LATE
MORNING AND EARLY AFTERNOON. ISOLD SHRA/TSRA EXPECTED BY LATE AFTN
BUT WILL NOT ADDRESS IN TAFS ATTM.

EXTENDED OUTLOOK...CHANCE OF SHOWERS/THUNDERSTORMS EACH DAY WITH
MAINLY VFR. LESSER CHANCES SUNDAY AND MONDAY.

&&

.MARINE...
NEAR TERM /THROUGH TONIGHT/...
AS OF 700 PM WEDNESDAY...VERY WEAK COLD FRONT WHICH HAD TURNED WINDS
TO THE E/NE FROM FRYING PAN SHOALS AND NE...HAS RETREATED THIS
EVE...SO WINDS HAVE RETURNED TO THE SE AT THE LOCAL BUOYS. THIS
TREND WILL CONTINUE OVERNIGHT AS THE BERMUDA HIGH REMAINS ENTRENCHED
ACROSS THE AREA...AND WINDS WILL SLOWLY TURN TO THE SW. GRADIENT
WILL BECOME WEAKER OVERNIGHT...SO SPEEDS ARE EXPECTED TO DROP TO
AROUND 10 KTS...MAINTAINING SEAS OF 2-3 FT WITH A LOW-AMPLITUDE SE
SWELL AND WEAK SW WIND CHOP COMPRISING THE SPECTRUM.

SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
AS OF 300 PM WEDNESDAY...WITH UPPER RIDGE THURSDAY AND DEVELOPING
SFC TROUGH/LOW ON FRIDAY...SOUTHWEST FLOW WILL CONTINUE WITH
SUSTAINED WINDS AROUND 15 KTS AND GUSTS TO NEAR 20 KTS...BECOMING
MORE SOUTHERLY IN THE AFTERNOON HOURS. AS FOR SEAS...EXPECT MAINLY 2
TO 4 FTERS...WITH LONG PERIOD SWELL BEING OVERCOME BY WIND WAVES
INTO FRIDAY.

LONG TERM /SATURDAY THROUGH MONDAY/...
AS OF 300 PM WEDNESDAY...SOUTHWEST WINDS OF 10-15 KNOTS WILL PREVAIL
ACROSS THE WATERS THROUGH THE PERIOD. FROM SUNDAY AFTERNOON UNTIL
MONDAY MORNING WINDS GET A BUMP WITH THE ENHANCEMENT OF THE PIEDMONT
TROUGH. THE INCREASE IN WINDS SEEMS TO BE EVER CHANGING REGARDING
TIMING SO CONFIDENCE IS NOT HIGH. REGARDLESS WINDS INCREASE TO 15-20
KNOTS WHILE DROPPING BACK LATER MONDAY. STANDARD MOSTLY WIND DRIVEN
SEAS WITH THESE WINDS WITH 2-3 FEET INCREASING TO 2-4 FEET AT TIMES
WITH THE HIGHER WINDS.
