AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
807 PM EDT WED JUL 4 2012

.SYNOPSIS...
A COLD FRONT WILL SLOWLY APPROACH FROM THE NORTHWEST THIS
EVENING...PRECEDED BY A TROUGH ACROSS THE AREA. THE FRONT WILL
CROSS THE AREA LATE TONIGHT. WEAK HIGH PRESSURE THEN BUILDS IN
THROUGH THURSDAY NIGHT. FAIR WEATHER ON FRIDAY WILL GIVE WAY TO
INCREASING HEAT AND A CHANCE OF THUNDERSTORMS SATURDAY. ADDITIONAL
STORMS MAY FIRE ON SUNDAY BEFORE A COOL FRONT EXITS LATE IN THE
DAY. THE PASSAGE OF THE FRONT WILL RESULT IN SEASONAL WEATHER
THROUGH THE BEGINNING OF NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
SCATTERED THUNDERSTORMS OVER SW CT AND JUST TO THE NW OF ORANGE
COUNTY SHOULD SURVIVE WITH THE GIVEN SBCAPES. WEAK FORCING FROM A
MID LEVEL SHORTWAVE APPARENTLY IS HELPING THESE STORMS TO DEVELOP. AN
UPPER JET STREAK PASSES TO THE NE LATER TONIGHT WITH THE CWA IN
AN UNFAVORABLE QUADRANT FOR DEEP SYNOPTIC LIFT. SCATTERED
THUNDERSTORMS MAINLY FOR THE WESTERN TWO-THIRDS OF THE CWA THIS
EVENING. HIGH CAPE VALUES IN THE HAIL GROWTH REGION WILL SUSTAIN A
CHANCE OF AT LEAST SMALL HAIL WITH SOME OF THESE STORMS ALONG WITH
STRONG WIND GUSTS. SPC HAS INCLUDED THE AREA WITHIN REGION OF
SLIGHT RISK FOR SEVERE THUNDERSTORMS FOR THIS EVENING. BY
MIDNIGHT...ATMOSPHERE SHOULD STABILIZE ENOUGH TO GO WITH A DRY
FORECAST OVERNIGHT.

A VERY MUGGY NIGHT IS IN STORE WITH DEW POINTS IN THE MID TO UPPER
60S. THE HEAT ADVISORY WILL REMAIN UP ACROSS NYC METRO AND
PORTIONS OF NE NJ THROUGH 8 PM.

OVERNIGHT LOWS WILL GENERALLY BE IN THE UPPER 60S TO LOWER
70S...WHICH IS SEVERAL DEGREES ABOVE NORMAL.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/...
HIGH PRESSURE AND NW FLOW WILL SEND A DRIER AIR MASS INTO THE
REGION ON THURSDAY...ALTHOUGH WITH THE OFFSHORE FLOW...HIGH
TEMPERATURES WILL ONLY BE SLIGHTLY COOLER. IN THE CASE OF COASTAL
LOCATIONS...IT ACTUALLY WILL BE SEVERAL DEGREES WARMER THAN WED.

MODELS ARE SLIGHTLY AT ODDS WITH THE MAGNITUDE OF THE CUTOFF LOW
THAT FORMS OFF THE COAST OF THE NOVA SCOTIA THU INTO THU NIGHT.
THE NAM IS A BIT DEEPER...SENDING THE FRONTAL BOUNDARY SOUTH
TOWARD THE MID ATLANTIC STATES. THE GFS IS WEAKER AND FARTHER
NORTH WITH THE BOUNDARY. IN EITHER CASE...SPLITTING THE DIFFERENCE
PRODUCES HIGHS IN THE UPPER 80S TO LOWER 90S. THE AIR MASS WILL
ALSO BE NOTICEABLY DRIER WITH DEW POINTS DROPPING INTO THE UPPER
50S IN THE AFTERNOON. THIS PRODUCES HEAT INDEX VALUES CLOSE TO IF
NOT LOWER THAN THE AMBIENT TEMPERATURE. THUS...THE HEAT ADVISORY
FOR NYC HAS BEEN CANCELLED FOR THU.

A DEEP-LAYERED NW FLOW WILL PROVIDE MAINLY CLEAR SKIES THU AND THU
NIGHT. LOW THU NIGHT WILL RETURN TO NEAR NORMAL LEVELS .

&&

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
DRY NW FLOW ALOFT SO DRY WEATHER FRI. SIGNIFICANT DIFFERENCES IN
MODEL HIGH TEMPS. THE NAM IS THE COLDEST OF THE MAJOR SOLNS.
SUPPRESSION OF HEIGHTS S OF THE MARITIMES SEEMS TO BE THE MAIN
FACTOR. FOR THIS REASON...HAVE SIDED CLOSE TO THE WARMER 00Z ECMWF
AND 12Z GFS DATA DUE TO BETTER GLOBAL MODELING.

NAM CONTINUES AS AN OUTLIER FOR SAT. THE 00Z ECMWF IS HOT WITH RAW
DATA YIELDING HIGHS AROUND 100 NERN NJ. HAVE CONTINUED WITH THE
WARMER GUIDANCE FROM THE ECMWF AND GFS. ALL MODELS BRING CONVECTION
INTO THE CWA IN THE AFTN AND EVE AHEAD OF A COOL FRONT. IF THE
ECMWF/GFS VERIFY...INSTABILITY WILL ALLOW FOR SVR CHANCES.

THE FRONT LAGS BEHIND AND DOESN/T PASS TIL SUN AFTN/EVE. FOR THIS
REASON...HAVE MAINTAINED SLIGHT CHANCES FOR TSTMS AND BOOSTED TEMPS
TOWARDS THE HIGH END GFS ENSEMBLE DATA WITH RESIDUAL LLVL HOT AIR
TRAPPED IN THE REGION.

IT APPEARS THINGS SETTLE DOWN MON AND BEYOND AS THE FRONT REMAINS
STALLED S OF THE CWA. THIS WOULD RESULT IN FAIR WEATHER AND SEASONAL
TEMPS...AND THE FCST FOLLOWS THIS THINKING.

&&

.AVIATION /00Z THURSDAY THROUGH MONDAY/...
A WEAK COLD FRONT PASSING THROUGH TONIGHT. HIGH PRESSURE BUILDS
IN THE WAKE OF THE FRONT. VFR CONDITIONS FOR THE PERIOD.

THERE REMAINS THE POSSIBILITY OF ISO TSRA THROUGH THIS EVENING.
HOWEVER...WITH LOW CONFIDENCE ON THE TIMING AND LOCATIONS OF
IMPACT...HAVE REFRAINED FROM MENTIONING IN NYC TERMINALS.

EXPECTATION IS FOR SCATTERED TSRA OVER THE MID-HUDSON VALLEY TO
WEAKEN OVER THE NEXT HOUR OR TWO AS THEY APPRAOCH THE CITY
TERMINALS. THERE IS ONLY A LOW PROBABILITY FOR THESE STORMS TO
ORGANIZE INTO A LINE AS THEY APPROACH THE NYC TERMINALS.

VFR AND GUSTY WNW WINDS EXPECTED TO DEVELOP BY LATE MORNING
THURSDAY AND CONTINUE THROUGH THE AFTERNOON. WINDS ARE EXPECTED TO
GENERALLY BE RIGHT OF 310 TRUE.
