AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE NEW YORK NY
253 PM EDT THU JUN 9 2011

.SYNOPSIS...
BERMUDA HIGH OVER THE ATLANTIC WILL CONTINUE TO BRING HOT AND HUMID
CONDITIONS ACROSS THE AREA. A COLD FRONT WILL MOVE THROUGH THE
REGION TONIGHT THROUGH FRIDAY MORNING. THIS FRONT WILL STALL SOUTH
OF THE AREA ON FRIDAY AS HIGH PRESSURE SLIDES TO OUR NORTH. THE
FRONT WILL RETURN NORTH AS A WARM FRONT LATE FRIDAY NIGHT THROUGH
SATURDAY...BEFORE A STRONGER COLD FRONT FROM THE WEST MOVES THROUGH
ON SUNDAY. HIGH PRESSURE WILL RETURN FOR EARLY NEXT WEEK.

&&

.NEAR TERM /UNTIL 10 PM THIS EVENING/...
SEVERE THUNDERSTORM WATCH #452 IN EFFECT FOR OUR ENTIRE FORECAST
AREA THROUGH 10 PM EDT FOR SEVERE THUNDERSTORMS WITH LARGE HAIL
AND DAMAGING WINDS.

ANOTHER HAZY...HOT AND HUMID DAY ON TAP FOR THE TRI-STATE AREA.
FLOW A BIT MORE WESTERLY...AND FOR NYC AND PARTS OF NE NJ...THIS
COULD MEAN MORE IN THE WAY OF MIXING...WHICH WOULD RESULT IN
SLIGHTLY LOWER SFC DEWPOINTS...BUT SLIGHTLY HIGHER MAX TEMPS DUE
TO THE SLIGHTLY DRYER ATMOSPHERE. SEA BREEZE SHOULD BE LIMITED TO
THE IMMEDIATE COAST...AS SFC WINDS SHOULD RANGE FROM 10-15 MPH.

MAX TEMPS 95-100 IN/AROUND NYC AND URBANIZED AREAS OF NE NJ WITH A
HEAT INDEX 98-102. OTHERWISE...HIGHS IN THE LOW TO MID 90S
ELSEWHERE AND IN THE UPPER 80S TO LOWER 90S ALONG THE IMMEDIATE
COAST. A FEW SPOTS INLAND COULD REACH THE UPPER 90S.

HEAT ADVISORY REMAINS UP FOR NYC AND MOST OF NE NJ THROUGH THIS
EVENING.

HIGHLY UNSTABLE AIRMASS DEVELOPS TODAY...AND CAPE VALUES
INCREASING TO 3000-5000 J/KG AND A LIFTED INDEX ANYWHERE FROM -5C
TO -8C. HOWEVER...WITH THE SFC LOW PASSING THROUGH NORTHERN NY AND
NORTHERN NEW ENGLAND...AND H5 SHORTWAVE PASSING NORTH OF THE
AREA...WILL HAVE TROUBLE FINDING A TRIGGERING MECHANISM FOR
CONVECTION THIS AFTERNOON AND INTO EARLY THIS EVENING. SHEAR
VALUES QUITE LOW. DUE TO THE INSTABILITY OVER THE REGION...ANY
STORMS THAT DEVELOP HAVE THE POTENTIAL TO BECOME SEVERE...AND THE
STORM PREDICTION CENTER HAS THE REGION IN A SLIGHT RISK FOR SEVERE
THUNDERSTORMS...BUT WITH THE BULK OF THE FORCING WELL NORTH OF THE
REGION...WILL ONLY CARRY CHANCE POPS.

&&

.SHORT TERM /10 PM THIS EVENING THROUGH 6 PM FRIDAY/...
SHOWERS AND THUNDERSTORMS TAPER OFF THROUGH THIS EVENING...AND
COLD FRONT SAGS SOUTH OF THE REGION BY LATE TONIGHT AND STALL
SOUTH OF THE REGION. WITH NORTHERLY WINDS AND A COOLER...LESS
HUMID AIRMASS BEGINS TO BUILD INTO THE REGION. LOW PRES DEVELOPS
OVER THE MID-ATLANTIC ON FRI...AND SOME DEVELOPING SHOWERS AND
THUNDERSTORMS WILL BEGIN TO PUSH EASTWARD TOWARDS WESTERN PORTIONS
OF THE FORECAST AREA. TEMPS ON FRI WILL STILL BE SEVERAL DEGREES
ABOVE NORMAL...TOPPING OFF IN THE MID-UPPER 80S IN/AROUND NYC AND
IN THE LOW TO MID 80S ELSEWHERE. HIGHS WILL BE IN THE 70S ALONG
THE COAST.

&&

.LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/...
MODEL CONSENSUS HAS THE FRONT STALLING TO OUR SOUTH FRIDAY NIGHT
WITH THROUGH SATURDAY WITH HIGH PRESSURE TRYING TO BUILD IN FROM
THE NORTH. LOW PRESSURE MEANWHILE MOVES THROUGH THE GREAT LAKES
REGION. KEPT IN SLIGHT CHANCE TO CHANCE POPS WITH MOISTURE STREAMING
IN FROM THE WEST. ENOUGH ELEVATED INSTABILITY FOR A SLIGHT CHANCE OF
A THUNDERSTORM MAINLY ACROSS THE WESTERN ZONES...WHERE POPS ARE
GENERALLY HIGHER.

THE BOUNDARY TO THE SOUTH ADVANCES NORTHWARD AS A WARM FRONT
SATURDAY NIGHT...WITH MODELS BRINGING IT AT LEAST PARTIALLY THROUGH
THE CWA DURING SUNDAY MORNING. A WEAK LOW OR TRIPLE POINT MAY FORM
AND PASS RIGHT OVER US IN THE PROCESS. AN OVERALL BETTER CHANCE OF
RAINFALL WITH AGAIN A CHANCE OF A THUNDERSTORM SATURDAY NIGHT AND
SUNDAY...BUT WILL CAP POPS AT HIGHER-END CHANCE FOR NOW.

THE STORM SYSTEM THEN SHIFTS EAST SUNDAY NIGHT AND MONDAY WITH LAST
CHANCES OF RAINFALL POSSIBLY BEFORE SUNRISE ON MONDAY...BUT WILL
KEEP LOW-END POPS MONDAY MORNING TO ACCOUNT FOR SOME UNCERTAINTY IN
THE TIMING OF THE SYSTEM. HIGH PRESSURE THEN LIKELY KEEPS US DRY
THROUGH WEDNESDAY.

&&

.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
A COLD FRONT WILL MOVE THROUGH THE REGION FROM THE WEST THIS EVENING.

SHOWERS/TSTMS HAVE BEGUN TO DEVELOP OVER CENTRAL PA AND SRN NY
STATE. BASED ON RADAR EXTRAPOLATION OF THESE STORMS...ADDED TSTMS
TO TAFS FM 20-22Z OVER KEWR/KTEB/KSWF AND 21-23Z FOR KJFK/KLGA/KHPN...THEN
LATER FOR TERMINALS E OF NYC. TSTMS MAY INCLUDE PERIODS OF HEAVY
RAIN...GUSTY WINDS AND HAIL. AMENDMENTS THIS AFTERNOON WILL FINE-
TUNE TIMING AND THESE FEATURES. CB GROUPS INCLUDED IN TAFS AFTER
THE INITIAL BATCH OF TSTMS...AND REDEVELOPMENT IS POSSIBLE BEFORE
THE COLD FRONT MOVES THROUGH THE REGION.

IN TERMS OF WINDS...SEA BREEZE HAS DEVELOPED OVER COASTAL
TERMINALS WITH S FLOW...AND GENERAL SW FLOW HAS DEVELOPED INLAND.
GUSTS WILL BE LIKELY THIS AFTERNOON AS WINDS ALOFT INCREASE. THIS
GENERAL FLOW MAY BE DISRUPTED AS TIMES BY OUTFLOW BOUNDARIES FROM
DISTANT TSTMS WITH WIND DIRECTIONS CHANGING QUICKLY OR BECOMING VARIABLE.

COLD FRONT MOVES TONIGHT...WITH VFR CONDITIONS PREVAILING AND
WINDS BECOMING NW.
