What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS New York, NY wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 4, 4:07 PM EDT, 26 minutes earlier.

Area forecast discussion, Jul 4, 4:07 PM EDT, 26 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
407 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/...
ISOLATED CONVECTION FINALLY BREAKING OUT ACROSS THE LOWER HUDSON
VALLEY AS A MID LEVEL CAPPING INVERSION IS OVERCOME BY DAYTIME
HEATING. CURRENT THINKING IT THAT COVERAGE WILL BE WIDELY SCT
THROUGH THIS EVENING AS A WEAK TROUGH PROGRESSES SE ACROSS THE
AREA AHEAD OF COLD FRONT DROPPING SE ACROSS THE GREAT LAKES. THE
LATTER OF WHICH WILL PASS THROUGH LATE TONIGHT AND USHER IN A
DRIER AIR MASS TOWARD MORNING.

AN UPPER JET STREAK PASSES TO THE NE TONIGHT AND SHOULD LIMIT THE
CONVECTION FROM BECOMING ORGANIZED. THE HRRR MODEL DOES SHOW SOME
CONSOLIDATION OF THESE AIR MASS THUNDERSTORMS ALONG THE PRE-
FRONTAL TROUGH THROUGH 00Z...DROPPING A LINE ACROSS THE NYC
METRO. THIS WILL NEED TO BE CLOSELY WATCHED...BUT SEEMS LIKE AN
OUTLIER AT THIS TIME.

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.

A MODERATE RISK OF RIP CURRENTS CONTINUES AT ATLANTIC OCEAN
BEACHES THROUGH THIS EVENING.

&&

.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 /20Z WEDNESDAY THROUGH MONDAY/...
A WEAK TROUGH PERSISTS THIS AFTERNOON...WITH A COLD FRONT PASSING
THROUGH TONIGHT. HIGH PRESSURE BUILDS IN THE WAKE OF THE FRONT. VFR
CONDITIONS FOR THE PERIOD.

A TROUGH REMAINS IN PLACE JUST WEST OF THE CITY TERMINALS...PRODUCING
A SWLY FLOW TO THE EAST...AND A WLY TO WNWLY FLOW TO THE WEST.
WINDS GENERALLY AROUND 10 KTS...WITH A FEW GUSTS IN THE COASTAL
TAF SITES. THE SEA BREEZE PASSAGE AT KJFK AND KISP WILL KEEP WINDS
MORE SLY FOR THE AFTN.

THERE REMAINS THE POSSIBILITY OF ISO TO SCT TSTORM LATE THIS AFTN
AFTER 20Z. HOWEVER...WITH LOW CONFIDENCE ON THE TIMING AND
LOCATIONS OF IMPACT...HAVE REFRAINED FROM MENTIONING IN TAFS. BEST
CHC FOR ANY DEVELOPMENT WILL BE ALONG THE SURFACE TROUGH EXTENDING
THROUGH THE CITY AND NE NJ.
