AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
351 PM EDT WED JUL 9 2014
.SYNOPSIS...
A COLD FRONT SWINGS THROUGH THE REGION TONIGHT...STALLING JUST TO
THE SOUTH ON THURSDAY. HIGH PRESSURE WILL BUILD OVER THE AREA
FOR THE FIRST HALF OF THE WEEKEND...THEN SLIDE OFFSHORE THROUGH
THE BEGINNING OF NEXT WEEK.
&&
.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
MAIN CONCERN FOR THE LATE AFTN THROUGH THIS EVENING WILL BE THE
DEVELOPMENT OF ISO-SCT STRONG-SVR TSTMS OUT AHEAD OF AN
APPROACHING COLD FRONT. INITIAL DEVELOPMENT ALREADY OCCURRING LATE
THIS AFTN ALONG PRE FRONTAL TROUGH AND ASSOCIATED WITH PASSING
VORT MAX. THOUGH NOT AS IMPRESSIVE AS PREVIOUS DAYS...STILL SEEING
SBCAPE VALUES PUSHING 1000 J/KG OVER INTERIOR REGIONS WHILE
STRONGER SHEAR VALUES BETWEEN 35-45 KTS CONTINUE.
HOWEVER...OVERALL EXPECTING BETTER DYNAMICAL FORCING WITH A
STRONGER FRONTAL BOUNDARY AT THE SFC AND THE PASSING SHORTWAVES
ALOFT. COVERAGE WILL INCREASE INTO THIS EVENING AS THE COLD FRONT
NEARS...THOUGH NOT EXPECTING MORE THAN SCT COVERAGE OVER INTERIOR
REGIONS. MAIN THREATS ASSOCIATED WITH THE STORMS WILL BE GUSTY-
DAMAGING WINDS...WITH POSSIBLE HAIL. ONSHORE FLOW TODAY KEEPING
A MORE STABLE AIRMASS IN PLACE AT THE COAST...SO EXPECTING MINIMAL
STRONG-SVR THREAT AND EVEN COVERAGE.
COLD FRONT FINALLY REACHES THE AREA AFTR 00Z...THEN PROGRESSES
THROUGH TONIGHT...EVENTUALLY STALLING JUST SOUTH OF LONG ISLAND BY
12Z THURS MORNING. WILL CONTINUE TO MENTION THE SLIGHT CHC POTENTIAL
FOR PCPN RIGHT ALONG THE FRONT. WEAK LOW PRESSURE FORMS ALONG THE
FRONT LATE TONIGHT...WITH THE MESO MODELS IN GOOD AGREEMENT OF PCPN
THEN MOVING TO THE NORTH FROM THE DELMARVA REGION. HOWEVER...THE
CONFIDENCE OF IT REACHING LONG ISLAND/NYC METRO ON THE LOWER END AND
WILL JUST HAVE CHC POPS OVER THE OCEAN WATERS.
COOLER AIR WILL BE SLOW TO MOVE IN...SO WILL HAVE ONE MORE NIGHT
OF SLIGHTLY ABOVE NORMAL TEMPS. SIDED MORE WITH A MET SOLUTION FOR TEMP/DEW
PT.
THERE IS A HIGH RISK FOR RIP CURRENT DEVELOPMENT ON ALL ATLANTIC
OCEAN BEACHES THROUGH THIS EVENING.
&&
.SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/...
AS THE MODELS HAVE BEEN SHOWING FOR THE PAST COUPLE OF DAYS...COLD
FRONT PUSHES SOUTH AND REMAINS STALLED JUST SOUTH OF LONG ISLAND.
MULTIPLE WEAK LOWS RIDE THE FRONT TOMORROW INTO TOMORROW NIGHT.
OVERALL...EXPECTING DRIER AIR TO MOVE IN. BUT THERE MIGHT BE JUST
ENOUGH MOISTURE LEFT IN THE ATMO COMBINING WITH DECENT FORCING
ASSOCIATED WITH THE FRONT IN THE VICINITY AT THE SFC AND PASSING
SHORTWAVES ROUNDING THE BASE OF THE UPPER LVL TROUGH TO GENERATE AN
ISO SHOWER OR EVEN TSTM IN THE AFTN. WILL KEEP SLIGHT CHC WORDING IN
FOR NOW DURING THE PERIOD...WITH A GOOD CHC OF MOST OF THE REGION
REMAINING DRY THOUGH.
TEMPS FINALLY DROP DOWN TO NEAR NORMAL...USING A GENERAL BLEND OF
MET/MAV GUIDANCE.
THERE IS A MODERATE RISK OF RIP CURRENT DEVELOPMENT ALONG ALL OF
THE ATLANTIC OCEAN BEACHES.
&&
.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
MODEL CONSENSUS IS THAT THE FRONT WILL BE OFFSHORE BY FRI
MRNG...WITH DRY WX ACROSS THE CWA. THERE WILL BE PCPN GENERATED
ALONG THE FRONT...AND THE PROGS ARE FAIRLY CLOSE TO THE SHORE...SO
THE EXACT SPEED WILL NEED TO BE WATCHED AS ANY SLOWDOWN COULD RESULT
IN RAIN AT LEAST FRI MRNG. HIPRES THEN BUILD INTO THE REGION LATE
FRI THRU SAT. ALTHOUGH THE GFS AND ECMWF SUGGEST SOME ISOLD
SHRA/TSTMS SAT ALONG THE CWA PERIPHERY...HAVE SIDED CLOSER TO THE
NAM WHICH KEEPS THE CONVECTIVELY FAVORABLE INSTABILITY FURTHER W.
THE SHORES WILL BE DRY REGARDLESS...WITH THE MAIN UNCERTAINTY ACROSS
THE WRN INTERIOR. THE HIGH DRIFTS OFFSHORE SUN AND SETTLES OVER THE
ATLANTIC THRU THE BEGINNING OF NEXT WEEK. AFTN AND EVE TSTMS
POSSIBLE ON SUN...ESPECIALLY INTERIOR...AS RETURN FLOW INCREASES
MOISTURE AND INSTABILITY. A STRONG CLOSED H5 LOW THEN DROPS INTO THE
UPR GREAT LAKES MON AND TUE. SINGLE DIGIT H85 TEMPS WITH THIS ACROSS
NRN MN INTO THE UP. THE SW FLOW AHEAD OF THE LOW WILL PUMP WARM
HUMID AIR INTO THE REGION FOR MON AND TUE. THIS SETUP WILL HAVE THE
POTENTIAL TO PRODUCE A SVR OUTBREAK AT SOME POINT MON-TUE.
&&
.AVIATION /20Z WEDNESDAY THROUGH MONDAY/...
COLD FRONT CONTINUES TO WORK ITS WAY INTO THE REGION FROM THE
WEST...AND WILL MOVE ACROSS THE TERMINALS AFTER MIDNIGHT TONIGHT.
TSTMS DEVELOPING TO THE WEST. KSWF WILL BE MOST IMPACTED THROUGH
00Z...AND THEN MAIN TIMING FOR TSTMS AT
KJFK/KLGA/KEWR/KTEB/KSWF/KHPN WILL BE FROM 00-06Z THURSDAY. DUE TO
THE SCATTERED NATURE OF THE CONVECTION...WILL LEAVE OUT OF TAFS FOR
NOW...AND WILL SEND AMDS TO THE TAFS AS STORMS DEVELOP AND CAN
PINPOINT IMPACTS TO TERMINALS.
OTHERWISE...MAINLY VFR. SW FLOW...TURNING S AT COASTAL TERMINALS
BEHIND THE SEA BREEZE. WINDS MAINLY 10-15 KT THROUGH THIS EVENING.
WINDS BECOME SW 4-8 KT THIS EVENING. AFTER COLD FRONT MOVES ACROSS
THE TERMINALS...WINDS SHIFT TO THE N.
