AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
221 PM EDT TUE JUL 13 2010
.SYNOPSIS...
A WEAK TROUGH OF LOW PRESSURE WILL REMAIN IN THE VICINITY TODAY. LOW
PRESSURE THEN FORMS ALONG THIS TROUGH...AND PUSHES THROUGH THE
REGION TONIGHT INTO EARLY WEDNESDAY MORNING. THE LOW DEPARTS TO THE
NORTHEAST LATER IN THE DAY ON WEDNESDAY AS AN UPPER LEVEL
DISTURBANCE MOVES THROUGH. HIGH PRESSURE THEN BUILDS IN THURSDAY
INTO FRIDAY.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
CONVECTION BLOSSOMING AND APPROACHING THE CITY. FORECAST UPDATED
AGAIN TO RAMP UP RAINFALL AMOUNTS. 1-3 INCHES POSSIBLE IN THE
HEAVIEST ACTIVITY.
THERE IS A MODERATE RISK FOR RIP CURRENTS ALONG THE ATLANTIC
SHORES TODAY INTO THIS EVENING.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY/...
H5 TROUGH AND ASSOCIATED SHORTWAVE APPROACH FROM THE WEST TONIGHT.
ASSOCIATED WEAK LOW CENTER EXPECTED TO MOVE FROM THE MID ATLANTIC
THROUGH THE CWA DURING THIS TIME. FORCING FROM THE SURFACE LOW AND
FROM ALOFT WILL BRING OUR BEST OVERALL CHANCES OF RAINFALL.
AGAIN...SOME THUNDERSTORMS WITH HEAVY RAINFALL ARE POSSIBLE. PLEASE
SEE HYDROLOGY SECTION FOR MORE DETAILS.
LOW CENTER DEPARTS TO THE NORTHEAST EARLY WEDNESDAY MORNING WITH THE
TRAILING H5 TROUGH AXIS PASSING THROUGH LATE IN THE DAY TO EARLY
EVENING HOURS. LINGERING SHOWERS IN ASSOCIATION WITH THE SURFACE LOW
LIKELY FOR EASTERNMOST ZONES. OTHERWISE...CHC POPS WITH THE H5
TROUGH AXIS. ENOUGH SUNSHINE WITH AN OFFSHORE FLOW IN THE AFTERNOON
SHOULD ALLOW HIGHS FROM THE MID 80S TO LOW 90S. DEW POINTS SHOULD BE
ABLE TO MIX OUT AND DROPS A FEW DEGREES DURING THE AFTERNOON...BUT
IT WILL STILL BE A BIT MUGGY.
HIGH PRESSURE KEEPS THURSDAY DRY WITH MOSTLY SUNNY SKIES. FORECAST
H8 TEMPERATURES WOULD ALLOW FOR HIGHS IN THE LOW-MID 90S AWAY FROM
ONSHORE FLOW...HOWEVER WITH THE ONSHORE FLOW...DEWPOINTS PROBABLY
DON'T MIX OUT AS MUCH VS. WEDNESDAY. HEAT INDICES THEREFORE MAY
REACH AT LEAST 95 IN THE CITY.
COLD FRONT BEGINS TO MAKE A SLOW APPROACH FROM THE NORTHWEST. SLIGHT
CHANCE TO CHANCE POPS FOR SHOWERS AND THUNDERSTORMS FRIDAY
AFTERNOON. TEMPS ALOFT MODERATE FROM THURSDAY AND SUGGEST HIGHS IN
THE MID-UPPER 90S FOR URBANIZED NE NJ. HEAT INDICES IN THE CITY
WOULD ONCE AGAIN BE AT 95 OR ABOVE...SO THIS WILL NEED TO BE
MONITORED AS THE POTENTIAL FOR 2 DAYS IN A ROW OF 95+ HEAT INDICES
COULD HAPPEN.
&&
.LONG TERM /FRIDAY NIGHT THROUGH MONDAY/...
COLD FRONT EXPECTED TO PASS THROUGH SAT INTO SAT NIGHT. MODERATE
INSTABILITY WITH DAYTIME HIGHS AROUND 90 AND HIGH DEW POINTS IN THE
LOWER 70S WILL SET THE STAGE FOR AT LEAST SCT CONVECTION ALONG AND
AHEAD OF THE FRONTAL SYSTEM. THE ONE LIMITING FACTOR MAY BE A
CAPPING INVERSION WITH 85H TEMPS NEAR 20C...HOWEVER THE TROPICAL
NATURE OF THE AIR MASS SUPPORTS LOW LCL/LFC VALUES. THUS...HEAVY
DOWNPOURS LIKELY WITH ANY CONVECTION THAT DOES DEVELOP.
CONDITIONS DRY OUT BEHIND THE FRONT SUN INTO MON WITH LESS
HUMIDITY...BUT STILL FEW DEGREES ABOVE NORMAL WITH HIGHS IN THE MID
TO UPPER 80S...SLIGHTLY COOLER THOUGH ALONG THE SHORE.
&&
.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
LARGE AREA OF HEAVY RAIN WITH EMBEDDED THUNDERSTORMS IMPACTING NY
TRACON AIRSPACE. THE BACK EDGE OF THIS PRECIP IS MOVING THROUGH
KEWR/KTEB AT TIME...AND WILL CLEAR OUT OF THE JFK/LGA/HPN
TERMINALS WITHIN THE HOUR.
SOME UNCERTAINTY ON TIMING OF SHOWERS OVERNIGHT...AS WELL AS MVFR
CONDITIONS DUE TO FOG.

.MARINE...
HIGH PRES OVER THE AREA WILL WEAKEN TODAY AS A FRONTAL BOUNDARY
APPROACHES FROM THE NW AND LOW PRES DEVELOPS NEAR THE DELMARVA
PENINSULA. THE LOW WILL TRACK NE TONIGHT PASSING OVER THE WATERS
TONIGHT...THEN LIFTS INTO THE GULF OF MAINE ON WED.
CONDITIONS ARE EXPECTED TO REMAIN BELOW ADVISORY LEVELS THROUGH MOST
OF TONIGHT...BUT WAVEWATCH HAS BEEN INDICATING A WAVE PACKAGE OF 5-6
FT AT THE OFFSHORE BUOYS FOR THE LAST 24 HOURS. OBS UPSTREAM (OFF
THE CAROLINA COAST) INDICATE SEAS CURRENTLY AT 5 FT. A LONG
SOUTHERLY FETCH TODAY AND TONIGHT MAKES HIGH SEAS POSSIBLE LATE
TONIGHT...BUT MORE LIKELY ON WED. AFTER COLLABORATION WITH
SURROUNDING OFFICES...HAVE DECIDED TO HOLD OFF ON ISSUING A THIRD
PERIOD SCA FOR SEAS ON THE OCEAN SINCE IT IS DEPENDENT ON A SWELL
PACKAGE AND THESE ARE VERY TRICKY TO FORECAST. SEAS DIMINISH FROM W
TO E WED NIGHT. THE REST OF THE WATERS WILL REMAIN BELOW SCA LEVELS.
HIGH PRES BRIEFLY BUILDS BACK IN WED NIGHT WITH A WARM FRONT LIFTING
NORTH OF THE AREA ON THU...FOLLOWED BY A SLOW MOVING COLD FRONT THIS
WEEKEND. TRANQUIL CONDITIONS RETURN TO THE WATERS THU THROUGH SAT.
