AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
1048 AM EDT WED JUN 20 2012
.SYNOPSIS...
STRONG HIGH PRESSURE EXTENDING FROM THE OHIO VALLEY TO THE MID
ATLANTIC COAST WILL PROVIDE HOT AND HUMID CONDITIONS THROUGH
THURSDAY NIGHT. A COLD FRONT WILL APPROACH ON FRIDAY...AND MOVE
SLOWLY THROUGH FRIDAY AFTERNOON INTO FRIDAY NIGHT. LOW PRESSURE
WILL DEVELOP ALONG THE FRONT JUST EAST OF NEW ENGLAND ON
SATURDAY...WHILE WEAK HIGH PRESSURE BUILDS INTO THE AREA FOR THE
WEEKEND. A STRONG FRONTAL SYSTEM MAY AFFECT THE REGION MONDAY
INTO TUESDAY.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
REMAIN ON TRACK FOR THE FIRST OF TWO HOT...OPPRESSIVE DAYS ACROSS
THE TRI-STATE.
UPPER LEVEL RIDGING CONTINUES TO BUILD OVER THE REGION. WSW
BOUNDARY LAYER FLOW AROUND 10 KT WILL SERVE TO HELP DELAY
SEABREEZE PUSHING ONSHORE UNTIL LATE AFTERNOON...SO EVEN COASTAL
LOCATIONS WILL EXPERIENCE SOME HEAT...AND PLACES JUST INLAND WILL
NOT EXPERIENCE THE USUAL RELIEF FROM THE SEA BREEZE UNTIL LATE
AFTERNOON/EARLY EVENING.
BASED ON 12Z SOUNDINGS...12Z NAM 2-METER TEMPERATURES...AND 6Z MAV
GUIDANCE TRENDING TOWARDS WARMER 00Z MET GUIDANCE...HAVE GENERALLY
NUDGED UP HIGHS ABOUT A DEGREE. LATEST GUIDANCE ALSO SUGGESTS
DEWPOINTS THIS AFTERNOON WILL BE A DEGREE OR SO LOWER THAN
PREVIOUSLY FORECAST...SO STILL ON TRACK FOR HEAT ADVISORY CRITERIA
BEING MET FOR ALL BUT SUFFOLK COUNTY.
FOR NOW HAVE KEPT THE FORECAST DRY...BUT PAST FEW RUNS OF THE HRRR
ARE SUGGESTING THAT CONVECTION FORMS OVER THE HIGHER ELEVATIONS OF
NW CT/FAR WESTERN MA AND DRIFTS SE INTO CT ZONES. GIVEN EXPECTED
CAPES OF 2000-3000 J/KG EXPECT ANY CONVECTION WHICH WOULD MOVE
INTO THE CWA TO MAINTAIN ITSELF - WITH LOCALLY SEVERE STORMS
POSSIBLE. HOWEVER - GIVEN STRENGTH OF SUBSIDENCE UNDER THE RIDGE
AND A BIT OF A WARM BULGE IN THE SOUNDINGS FROM AROUND 800-700 HPA
NOT SURE IF THIS CAN BE OVERCOME FOR STORM FORMATION - HENCE
KEEPING THE FORECAST DRY AT THIS TIME. WILL CONTINUE TO MONITOR -
AND IF CHANCES FOR CONVECTIVE INITIATION INCREASE TO OUR NW -
WILL NEED TO ADD POPS ACROSS NORTHERN ZONES WITH THE NEXT UPDATE.
THERE IS A MODERATE RISK OF RIP CURRENTS AT OCEAN BEACHES TODAY.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM THURSDAY/...
UPPER LEVEL RIDGE AXIS MOVES INTO THE AREA IN THIS PERIOD WITHOUT
MUCH CHANGE IN AIR MASS. WARM TEMPS TONIGHT WITH A MODEL BLEND
YIELDING VALUES UPPER 60S TO LOWER 70S FOR MUCH OF THE AREA AND
MID 70S TO LOWER 80S NEAR THE CITY. THIS WILL BE FOLLOWED BY VERY
SIMILAR 850 MB TEMPS FOR THURSDAY BUT A WESTERLY FLOW THURSDAY
WILL ALLOW FOR DRIER AIR AND DEWPOINTS MORE IN THE MID TO UPPER
60S. HOWEVER...BETTER VERTICAL MIXING IS EXPECTED WITH MAX TEMPS A
FEW DEGREES HIGHER THAN ON WEDNESDAY. THEREFORE KEPT SAME
LOCATIONS IN HEAT ADVISORY WITH HEAT INDICES AROUND THE SAME
VALUES IN THE AFTERNOON. KEEPING WEATHER DRY FOR NOW AS DRIER LOW
LEVELS WILL BE A KEY INGREDIENT MISSING FOR ANY CONVECTIVE
DEVELOPMENT.
&&
.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
HEAT WILL GRADUALLY RELENT FRI INTO SAT AS A COLD FRONT APPROACHES
AND MOVES THROUGH.
FOR THU NIGHT...EXPECT VERY WARM CONDITIONS...WITH LOWS NEAR OR JUST
UNDER 80 IN MIDTOWN NYC...IN THE 70S MOST ELSEWHERE...AND UPPER 60S
IN SOME SPOTS WELL INLAND AND ACROSS ERN LONG ISLAND/CT. A MID LEVEL
VORTICITY MAXIMUM ROTATING ALL THE WAY AROUND THE UPPER HIGH FROM
ITS CURRENT POSITION OVER NORTH CAROLINA COULD SPARK A LATE NIGHT
TSTM...SO FCST CARRIES SLIGHT CHANCE POP.
FOR FRI...EXPECT A BETTER CHANCE OF TSTMS VIA DAYTIME
HEATING/INSTABILITY...APPROACHING MID LEVEL SHORTWAVE...AND EITHER
THE APPROACHING COLD FRONT OR A PRE-FRONTAL TROUGH. MAV/MET FORECAST
OF LIKELY POP FROM NYC WEST LOOKS TOO HIGH...EXPECT MORE SCATTERED
COVERAGE BEGINNING NORTH/WEST OF NYC AND THEN MOVING DOWN TOWARD THE
COAST. INSTABILITY AND BULK SHEAR NOT RUNNING VERY HIGH...SO EXPECT
ONLY AN ISOLD SEVERE THREAT. HIGHS DESPITE PARTIAL SUNSHINE SHOULD
RUN 90-95 IN NYC METRO...MOST OF LONG ISLAND AND THE INTERIOR
VALLEYS...WITH 80S IN THE HIGHER ELEVATIONS AND ALONG IMMEDIATE
SOUTH FACING COASTLINES.
MODELS ARE STILL IN DECENT AGREEMENT WITH THE COLD FRONT ONLY SLOWLY
SLIDING EAST OF THE AREA BY SAT MORNING AS THE SHORTWAVE AXIS
APPROACHES...SO CONVECTION MAY LINGER ACROSS EASTERN SECTIONS WELL
INTO FRI NIGHT. HIGH TEMPS ON SAT COULD STILL FLIRT WITH 90 IN NYC
AND URBAN NE NJ.
SHORTWAVE AXIS SLIDES EAST THROUGH THE REGION ON SATURDAY.
INSTABILITY CU AND A LINGERING SHOWER OR TSTM POSSIBLE ACROSS
EASTERN SECTIONS SATURDAY AFTERNOON.
OTHERWISE MEAN TROUGHING EXPECTED INTO EARLY NEXT WEEK...WITH
MODELS COMING INTO GOOD AGREEMENT WITH ANOMALOUSLY STRONG UPPER
LOW SWINGING FROM THE GREAT LAKES INTO THE NORTHEAST FOR MONDAY
INTO TUESDAY. AS A RESULT CONFIDENCE IS INCREASING ON AN UNUSUALLY
STRONG FRONTAL SYSTEM/SURFACE LOW AFFECTING THE REGION MONDAY INTO
TUESDAY.
&&
.AVIATION /15Z WEDNESDAY THROUGH SUNDAY/...
HIGH PRESSURE WILL REMAIN ACROSS THE TERMINALS THROUGH THE FORECAST
PERIOD. A SURFACE TROUGH DEVELOPS ALONG THE COAST BY LATE MORNING.
THE DEVELOPMENT OF THE TROUGH WILL AFFECT WIND DIRECTIONS ESPECIALLY
ALONG THE IMMEDIATE COAST. SEA BREEZE INFLUENCE IS ALSO POSSIBLE AT
KJFK AND KISP.

.MARINE...
MINOR CHANGES THIS UPDATE BASED ON LATEST TRENDS IN OBSERVATIONS
AND GUIDANCE. FORECAST APPEARS ON TRACK.
WINDS AND SEAS WILL REMAIN BELOW SCA LEVELS THROUGH THURSDAY
AFTERNOON. A SOUTHERLY LOW LEVEL JET ON THE OCEAN WATERS JUST S
OF NYC EARLY THU EVENING COULD GUST AS HIGH AS 20 KT...AND TSTMS
WITH AN APPROACHING COLD FRONT COULD POSE A THREAT FRI
AFTERNOON/NIGHT. OTHERWISE...SUB SCA CONDITIONS WILL
PREVAIL...WITH PREVAILING WINDS 15 KT OR LESS...AND MAX SEAS BELOW
5 FT.
&&
.HYDROLOGY...
MOSTLY DRY CONDITIONS EXPECTED THROUGH THURSDAY AFTERNOON. BASIN
AVG QPF FRI INTO FRI NIGHT SHOULD RUN FROM 1/4 TO 1/2 INCH.
WHILE PRECIPITABLE WATER VALUES WILL RUN FROM 1.5-1.75 INCHES ON
FRI...PRECIP EFFICIENCY WILL BE ONLY ABOUT AN INCH...AND TSTM
COVERAGE AHEAD OF AN APPROACHING COLD FRONT SHOULD BE SCT AT
MOST...SO EXPECT ONLY ISOLD POOR DRAINAGE FLOODING.
