AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
800 PM EDT SAT APR 16 2011
.SYNOPSIS...
LOW PRESSURE WITH A COLD FRONT MOVES THROUGH TONIGHT. HIGH PRESSURE
THEN GRADUALLY BUILDS IN DURING SUNDAY. A STATIONARY FRONT WILL
REMAIN TO THE SOUTH OF THE REGION ON MONDAY AND TUESDAY BEFORE
MOVING THROUGH AS A WARM FRONT ON WEDNESDAY. THIS WILL BE FOLLOWED
BY A COLD FRONT WEDNESDAY NIGHT AS LOW PRESSURE MOVES THROUGH
SOUTHEASTERN CANADA.
&&
.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
MODERATE TO HEAVY RAIN HAS BEEN FALLING ACROSS NE NJ AND THE LOWER
HUDSON VALLEY THE LAST COUPLE OF HOURS WITH RAINFALL RATES OF
THREE TENTHS TO ONE-HALF INCH AN HOUR. THIS HAS NECESSITATED AT
FLOOD ADVISORY FOR THE NYC METRO AND LOWER HUDSON VALLEY. SEVERAL
SMALL STREAMS ALSO ON THE RISE IN NE NJ...SO WILL BE MONITORING
FOR A POTENTIAL AREAL FLOOD WARNING THE NEXT COUPLE OF HOURS
SHOULD THESE RAINFALL RATES CONTINUE. FLOOD WATCH REMAINS UP FOR
NE NJ...WITH MINOR NUISANCE FLOODING POSSIBLE ACROSS THE ENTIRE
FORECAST AREA TONIGHT.
RAIN WILL CONTINUE TO OVERSPREAD THE CWA TONIGHT. WITH THE CWA
JUST NORTHEAST OF THE THETA-E RIDGE AND STRONGER ISENTROPIC LIFT
MOVING IN...RAIN MAY BE HEAVY AT TIMES WITHIN A FEW HOURS EITHER
WAY OF AROUND MIDNIGHT. FORECAST CAPES NOT TO IMPRESSIVE FOR
THUNDER...HOWEVER BASED ON OBSERVATIONS...THUNDER STILL POSSIBLE
JUST TO THE NORTHEAST AND SOUTH OF WHAT COULD BE A TRIPLE
POINT/SECONDARY LOW MOVING THROUGH LATER TONIGHT. SOME UPPER
SUPPORT TOO WITH JET STREAK MOVING THROUGH. SO HAVE LEFT IN A
CHANCE OF THUNDER FOR MOST OF THE CWA. BEST CHANCES RIGHT AHEAD
AND ALONG THIS TRIPLE POINT AND COLD FRONT EXTENDING SOUTHWARD
FROM IT.
WIND ADVISORY BEING CONTINUED OVER NYC/LONG ISLAND/COASTAL CT/NE
NJ/SRN WESTCHESTER. NAM SEEMS TO BE HANDLING EVOLUTION OF CURRENT
SYSTEM VERY WELL...INCLUDING DEVELOPING TRIPLE POINT LOW...WITH
EXPECTED PRESSURE FALLS AHEAD OF IT...AND RESULTANT INCREASE IN LOW
LEVEL JET (ALSO WELL CAPTURED BY NAM)...COULD VERY WELL SEE
SUSTAINED AND WIND GUST CRITERIA BEING MET...ESPECIALLY OVER LONG
ISLAND. LEAST CONFIDENT ABOUT NJ PORTION OF ADVISORY...BUT NOT
CONFIDENT ENOUGH TO LOWER IT THERE. HAVE EXTENDED ADVISORY OVER SE
COASTAL CT AND SUFFOLK COUNTY THROUGH 10Z...AND REMAINDER THROUGH 7Z
REFLECTING NAM FRONTAL TIMING. ALSO WILL MONITOR INTERIOR SE CT FOR
POSSIBLE NEED TO EXPAND ADVISORY DEPENDING ON HOW MUCH OF FORECAST
55-60 KT 850 WINDS ACTUALLY MIX DOWN...WOULD NEED 70-75 PERCENT TO
REACH ADVISORY CRITERIA...AND WITH STRONG MARINE INFLUENCE...NOT
SURE IF THAT CAN BE ACHIEVED.
TEMPERATURES ACTUALLY RISE DURING THE NIGHT WITH A STRONG SOUTHERLY
FLOW.
&&
.SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/...
LINGERING CHANCE OF RAIN FOR THE EASTERN ZONES BY DAYBREAK ON SUNDAY
WITH THE COLD FRONT MOVING THROUGH. SOME CLEARING IN THE
MORNING...BUT WITH CYCLONIC FLOW ALOFT AND A WET SOIL...EXPECTING
SOME CU BUILDUP LATE MORNING/AFTERNOON. SHORTWAVE ALOFT MOVES
THROUGH IN THE AFTERNOON/EVENING HOURS. WILL PUT IN A CHANCE OF
SPRINKLES FOR THE AFTERNOON. MAV/NAM MOS BLEND LOOKED GOOD FOR HIGHS.
GUSTY WSW-W WINDS LIKELY SUNDAY...WITH HIGH LOW LEVEL LAPSE RATES
ALLOWING FOR MIXING DOWN OF MOST IF NOT ALL OF 30-40 KT 950 HPA
WINDS. IN ADDITION RELATIVE TIGHT PRESSURE GRADIENT BETWEEN
DEPARTING LOW AND HIGH BUILDING IN WILL PROMOTE RELATIVELY STRONG
SURFACE WINDS OF 15-25 MPH TO GO ALONG WITH GUSTS UP TO 35 MPH -
HIGHEST NYC METRO/LONG ISLAND/COASTAL CT.
CLEARING SKIES AND DIMINISHING WINDS THEN EXPECTED SUNDAY NIGHT.
&&
.LONG TERM /MONDAY THROUGH SATURDAY/...
A NEARLY ZONAL FLOW ACROSS THE LOWER 48 TO START THE PERIOD WILL
FEATURE YET ANOTHER PAC STORM SYSTEM WHICH AMPLIFIES TO THE LEE OF
THE ROCKIES EARLY NEXT WEEK...SENDING A DEEPENING SFC LOW NE FROM
THE MID MS VLY WED INTO EASTERN CAN ON THU. MUCH LIKE THE SYSTEM WE
ARE EXPERIENCING TODAY...THERE IS UNCERTAINTY HOW FAR NORTH THE WARM
FRONT WILL GET BEFORE THE TRAILING COLD FRONT PASSES LATE WED NIGHT.
FROM A SENSIBLE WEATHER STANDPOINT...WE ARE LOOKING AT AN UNSETTLED
PERIOD WITH OVERRUNNING RAINS BREAKING OUT LATE MON...ALBEIT
LIGHT...THEN A LIGHT TO MODERATE RAIN TUE INTO WED. IT APPEARS THE
BEST THERMAL FORCING WILL RESIDE TO THE NORTH OF THE AREA WITH THE
HEAVIER RAIN. THE 12Z GFS PROVIDES ONE-QUARTER TO ONE-HALF INCH OF
RAINFALL ON TUE...WHILE THE NAM IS NEARLY DRY AS IT PLACES THE WARM
FRONT NORTH OF THE AREA. THE GLOBAL MODEL ENSEMBLE SUPPORTS A WARM
FRONT SOUTH OF THE AREA TUE...EVENTUALLY PUSHING TO THE NORTH ON
WED. THE LATTER OF WHICH IS ALWAYS QUESTIONABLE AT THIS TIME OF YEAR
WITH THE COLD NEAR SHORE WATERS...AND UPPER SUPPORT PASSING TO THE
NW. THERE DOES APPEAR TO A BE STRONG SW PUSH JUST AHEAD OF THE FRONT
WED AFT/EVE.
ANY CONVECTION AND ALONG AND AHEAD OF FRONT IS DEPENDENT ON WHETHER
THE FORECAST AREA GETS INTO THE WARM SECTOR. PLUS...THE TIMING OF
THE COLD FRONTAL PASSAGE WED NIGHT ONLY SUPPORTS MARGINAL
INSTABILITY. RIGHT NOW...LOOKS LIKE A MODERATE SHEAR...LOW CAPE
EVENT. THUS...WILL REFRAIN FROM MENTIONING THUNDERSTORMS IN THE
FORECAST AND STICK WITH SHOWERS.
HIGH PRESSURE BRIEFLY FOLLOWS THU INTO FRI BEFORE ANOTHER PAC
FRONTAL SYSTEM APPROACHES NEXT WEEKEND.
TEMPS WILL BE NEAR OR SLIGHTLY BELOW NORMAL MON INTO TUE WITH
OVERRUNNING CLOUDS/RAIN...THEN A POSSIBLE WARMUP WED ACROSS THE
INTERIOR PENDING THE WARM FRONTAL PASSAGE. HIGHS AROUND 70 WED AFT
INLAND...BUT ONLY IN THE 50S AT THE COAST DUE TO THE ONSHORE FLOW.
THE WEEK FINISHES OUT SLIGHTLY BELOW NORMAL BEHIND THE COLD FRONTAL
PASSAGE WED NIGHT.
&&
.AVIATION /00Z SUNDAY THROUGH THURSDAY/...
LOW PRESSURE WAS OVER THE GREAT LAKES WITH ANOTHER LOW THROUGH
CENTRAL VIRGINIA ON AN OCCLUDED FRONT WILL CROSS THE AREA LATE
TONIGHT.
A LOW LEVEL JET OF 60 TO 70 KT WILL RESULT IN WIND SHEAR 1500 TO
2000 FT...ENDING WEST TO EAST 07Z TO 10Z.
GUSTY SURFACE WINDS FROM THE SOUTHEAST...110 TO 140...AHEAD OF THE
FRONTAL SYSTEM WILL VEER TO THE SOUTHWEST...210 TO 230...BEHIND
THE FRONTAL SYSTEM. THERE COULD BE A BRIEF LULL IN THE WINDS FROM
10Z TO 13Z BEFORE INCREASING AND BECOMING GUSTY ONCE AGAIN...WITH
GUSTS TO 30 TO 35 KT DURING THE DAY SUNDAY.
IFR CEILINGS AND VISIBILITIES DEVELOPING AS MODERATE TO HEAVY RAIN
MOVES INTO THE AREA. NOT EXPECTING LIFR CONDITIONS...BUT CANNOT
BE RULED OUT COMPLETELY. SOME ISOLATED THUNDERSTORMS ARE IN THE
VICINITY OF THE NYC METRO TERMINALS AND WILL INCLUDE VCTS UNTIL
03Z. CHANCES FOR THUNDER AT THE OTHER TERMINALS IN MINIMAL AND
WILL NOT INCLUDE AT THIS TIME.
WITH THE WIND SHIFT VISIBILITIES AND CEILINGS WILL BE IMPROVING.
OUTLOOK FOR 00Z MONDAY THROUGH THURSDAY...
SUNDAY NIGHT...VFR WITH GUSTY WESTERLY WIND...DIMINISHING LATE.
MONDAY...VFR.
MONDAY NIGHT-WEDNESDAY...PERIODS OF SUB-VFR POSSIBLE IN SHOWERS
AND NIGHTTIME LOW STRATUS/FOG. GUSTY WINDS/LLWS POSSIBLE
WEDNESDAY.
WEDNESDAY NIGHT...PERIODS OF SUB-VFR POSSIBLE IN SHOWERS.
GUSTY WINDS/LLWS POSSIBLE. THUNDER ALSO POSSIBLE AHEAD OF A COLD
FRONT.
THURSDAY...VFR...WITH GUSTY NORTHWESTERLY WINDS.
&&
.MARINE...
GALE CONDITIONS ALL WATERS TONIGHT...COULD SEE SOME OCCASIONAL GUSTS
TO STORM FORCE OVERNIGHT OVER THE COASTAL OCEAN WATERS AS THE CORE
OF THE LOW LEVEL JET TRACKS OVERHEAD. SEAS BUILD TO 7 TO 13 FT ON
THE OCEAN IN RESPONSE TO THE STRONG WINDS AND TO 3 TO 6 FT ON THE
SOUND.
HAVE EXTENDED THE GALE WARNING ON THE COASTAL OCEAN WATERS EAST OF
MORICHES INLET THRU 21Z SUNDAY AS GALE GUSTS LIKELY TO CONTINUE
THROUGH MOST OF THE DAY. SCA CONDITIONS EXPECTED ELSEWHERE
SUNDAY...AND LIKELY ON ALL WATERS SUNDAY NIGHT WITH CONTINUED 25-30
KT GUSTS.
SUB-SCA CONDITIONS DEVELOP ON MON WITH A DIMINISHING WESTERLY FLOW.
POTENTIAL FOR MARGINAL SCA SEAS ON THE OCEAN TUE WITH A DEVELOPING
EASTERLY FLOW NORTH OF A WARM FRONT. SOME UNCERTAINTY EXISTS WITH
THE LOCATION OF THE WARM FRONT...BUT THINKING IS THAT A WARM FRONT
REMAINS SOUTH OF THE OCEAN WATERS TUE INTO WED MORNING. THIS WOULD
PLACE THE WATERS IN A PROLONGED PERIOD OF EASTERLY FLOW. THE WARM
FRONT THEN PASSES TO THE NORTH WED AFT...FOLLOWED BY A MODERATE SW
FLOW AND EVENTUALLY A W FLOW ON THU BEHIND THE TRAILING COLD FRONT.
MARGINAL SCA SEAS FORECAST TUE-WED ON THE OCEAN WATERS PRIOR TO THE
COLD FRONTAL PASSAGE. BEST CHANCE FOR SCA WINDS WILL BE ON THU IN
THE COLD ADVECTION AND W/NW FLOW BEHIND THE FRONT. SEAS ON THE
EASTERN OCEAN WATERS MAY RAMP UP TO 6 TO 7 FT ON THU.
UNDERCUT WAVEWATCH 1 TO 3 FT ON THU. SEAS APPEAR TO BE OVERDONE IN
THE WESTERLY FLOW.
&&
.HYDROLOGY...
RAINFALL THROUGH TONIGHT EXPECTED TO RANGE GENERALLY FROM AROUND
THREE QUARTERS OF AN INCH ACROSS EASTERN ZONES TO NEARLY 2 INCHES
ACROSS THE WESTERNMOST SECTIONS OF THE CWA. FLOOD WATCH REMAINS
UP FOR NE NJ BASED ON FLASH FLOOD GUIDANCE VALUES FOR 6 AND 12
HOUR QPF VALUES. WITHIN THE WATCH AREA...MINOR URBAN/POOR DRAINAGE
AREAS AND FLOOD PRONE AREAS ALONG SMALL STREAMS AND RIVERS WOULD
BE THE MOST LIKELY IMPACTS. ELSEWHERE...THERE IS ONLY JUST A
CHANCE FOR MAINLY URBANIZED/POOR DRAINAGE FLOODING.
A FLOOD WARNING HOWEVER REMAINS IN EFFECT FOR SPOTS ALONG THE
CONNECTICUT RIVER. PLEASE SEE WWW.WEATHER.GOV/NYC FOR MORE
INFORMATION.
POTENTIAL FOR AROUND ONE-HALF INCH OF RAINFALL TUE INTO WED NIGHT.
HIGHER AMOUNTS POSSIBLE IN ANY CONVECTION ALONG AND AHEAD OF COLD
FRONT WED NIGHT. THUNDERSTORM COVERAGE LOOKS TO BE ISOLATED AT THIS
TIME.
&&
.TIDES/COASTAL FLOODING...
HAVE DOWNGRADED COASTAL FLOOD WARNING TO AN ADVISORY FOR MAINLY
EASTERN PARTS OF LONG ISLAND SOUND AND EASTERN PARTS OF THE THE
ATLANTIC SHORES...MAINLY DUE TO ALL GUIDANCE SUGGESTING THAT
MODERATE THRESHOLDS WILL BE TOUGH TO REACH. THE GUIDANCE MAY INDEED
BE FORECASTING THE SURGE TO BE TOO LOW DUE TO A STRONG SE WIND THIS
EVENING...BUT KEPT THE WARNING UP WHERE GUIDANCE WAS COMING UP JUST
SHORT OR AROUND MODERATE COASTAL FLOODING THRESHOLDS.
TIDAL DEPARTURES OF 1 1/2 FT ARE NEEDED FOR MINOR COASTAL
FLOODING...AND THESE THRESHOLDS SHOULD BE MET. AROUND 2 FT
DEPARTURES WILL BE NEEDED FOR MODERATE COASTAL FLOODING.
WAVES AT THE OFFSHORE BUOYS (44065/44025/44017) OF 10-13 FT SUPPORT
6-9 FT BREAKING WAVES AT ATLANTIC BEACHES TONIGHT. AS A RESULT HAVE
ISSUED A HIGH SURF ADVISORY FOR THE APPLICABLE ZONES...WILL
EMPHASIZE THE POTENTIAL FOR WASHOVER AND MINOR TO MODERATE BEACH
EROSION.
