AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
726 AM EDT THU AUG 5 2010
.SYNOPSIS...
A HOT AND HUMID AIRMASS WILL DEPART TONIGHT WITH THE PASSAGE OF A
COLD FRONT. ANOTHER WEAK DISTURBANCE MAY IMPACT THE REGION ON
FRIDAY. OTHERWISE...CANADIAN HIGH PRESSURE WILL GRADUALLY BUILD
INTO THE REGION FOR THE WEEKEND.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
PRE-FRONTAL TROUGH ASSOCIATED SHOWERS AND THUNDERSTORMS EARLY
THIS MORNING WILL CONTINUE TO TRACK EAST. CLEARING IN ITS WAKE
SHOULD ALLOW FOR HOT AND HUMID CONDITIONS TO CONTINUE TODAY. SFC
DEWPOINTS WILL BE IN THE LOWER 70S AND HIGH TEMPS GENERALLY
CLIMBING INTO THE UPPER 80S TO AROUND 90...EXCEPT THE HOTTEST
TEMPS WILL OCCUR OVER NYC AND NE NJ. MAX TEMPS THERE WILL BE IN
THE MIDDLE TO UPPER 90S...RESULTING IN A HEAT INDEX RANGING FROM
95-100. HEAT ADVISORY CONTINUES THROUGH TODAY...ENDING AT 6
PM...WHEN THE HEAT INDEX IS EXPECTED TO DROP BELOW 95. AFTERNOON
CONVECTION COULD BRING AN EARLY END TO THE OPPRESSIVE HEAT.
COLD FRONT APPROACHES FROM THE WEST. WITH PWATS OVER 2"
THROUGHOUT...WILL KEEP THE MENTION OF HEAVY RAIN IN
THUNDERSTORMS. BASIN AVERAGES WILL GENERALLY RANGE FROM AROUND
1/4" TO 1/2"...BUT HEAVY DOWNPOURS COULD RESULT IN LOCAL RAINFALL
AMOUNTS OVER 1". LOCALIZED FLOODING...ESPECIALLY OF LOW-LYING AND
POOR DRAINAGE AREAS...IS POSSIBLE.
WILL BUMP UP POPS TO LIKELY FOR THE LATE AFTERNOON HOURS
THROUGHOUT WITH THE APPROACH AND PASSAGE OF THE COLD FRONT.
THERE IS A MODERATE RISK FOR RIP CURRENTS TODAY.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY/...
STORMS TAPER OFF THIS EVENING WITH LOSS OF DIURNAL HEATING AND
PASSAGE OF COLD FRONT AND JUST ABOUT ALL STORMS SHOULD BE OVER
AROUND MIDNIGHT TONIGHT. WITH A LIGHT NORTHERLY FLOW DEVELOPING...
ALONG WITH CLEARING SKIES AND LOW-LEVEL MOISTURE SLOW TO DEPART...
PATCHY FOG IS POSSIBLE AGAIN LATE TONIGHT...MAINLY IN OUTLYING
AREAS.
GENERALLY MOSTLY SUNNY SKIES ON TAP FOR FRI. UPPER TROUGH SLIDES
THROUGH THE REGION...POSSIBLY TOUCHING OFF SOME AFTERNOON SHOWERS
AND THUNDERSTORMS. WILL CARRY SLIGHT CHANCE...AS ONLY ISOLATED
STORMS EXPECTED ATTM. MUCH COOLER AND DRYER WITH HIGHS IN THE MID
TO UPPER 80S AND SFC DEWPOINTS DROPPING INTO THE 50S.
HIGH PRES MOVES OVERHEAD BY LATE SAT...MOVING OFFSHORE ON SUN.

H5 LOW WILL WEAKEN OVER ERN CANADA BY THE END OF THE WEEKEND WITH
AN UPPER LEVEL RIDGE BUILDING FROM THE GOMEX NWD INTO THE WRN
GREAT LAKES THROUGH THE MIDDLE OF NEXT WEEK.
OPERATIONAL MODELS AND ENSEMBLES ALL SUPPORT THIS PATTERN. THE
RESULT WILL BE INCREASING HEIGHTS SUN NIGHT WITH NW FLOW ALOFT
DEVELOPING MON. THIS SUPPORTS SEASONAL TEMPS AND THE FORECAST
FOLLOWS CLOSE TO THE MEN GUIDANCE. THE HEAT APPEARS IT WILL BE
SUPPRESSED SW OF THE CWA THROUGH THE PERIOD...WITH THE NRN EXTENT
REACHING INTO SRN PA/NJ BY WED.
POPS ARE 00Z GMOS MINUS 10 PERCENT TO ACCOUNT FOR THE MUCH DRIER
ECMWF SOLUTIONS. POPS ARE THEREFORE LIMITED TO SLIGHT CHANCE ON

CHOICE FOR THE TIMING OF THIS BOUNDARY. CHANCES WILL INCREASE
AFTER WED AS THE RIDGE BUILDS CLOSER AND THE RING OF FIRE
APPROACHES THE CWA.

MORNING...BUT 5-6SM IN HZ WILL LIKELY BE AN ISSUE THROUGH EARLY
AFTERNOON.
WILL HAVE CHANCE OF TSTMS AT KGON THROUGH AROUND 13Z. OTHERWISE...
WITH TROUGH HANGING OVER THE AREA AND APPROACHING COLD
FRONT...ADDITIONAL THUNDERSTORMS ARE POSSIBLE AT THE TERMINALS
AFTER MIDDAY TODAY. TOO MUCH UNCERTAINTY IN COVERAGE/LOCATION TO
INCLUDE EXPLICITLY AT THIS TIME. STRONG WINDS AND REDUCED VSBY IN
