AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
707 PM EDT WED APR 10 2013
.SYNOPSIS...
A WEAK WAVE OF LOW PRESSURE WILL MOVE EAST ALONG A FRONT STALLED
TO THE SOUTH TONIGHT. THIS LOW WILL PULL THE FRONT FARTHER SOUTH
THURSDAY INTO THURSDAY EVENING. THE FRONT WILL THEN SLOWLY
APPROACH AGAIN AS A WARM FRONT LATE THURSDAY NIGHT. A FRONTAL
SYSTEM WILL MOVE THROUGH ON FRIDAY...THEN A COLD FRONT WILL PASS
THROUGH ON SATURDAY...WITH HIGH PRESSURE BUILDING OVER THE REGION
TO END THE WEEKEND. A WARM FRONT WILL APPROACH ON MONDAY... AND
MAY LINGER NEARBY INTO THE MIDDLE OF NEXT WEEK.
&&
.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
LINE OF TSTMS CURRENTLY TRACKING THROUGH THE WESTERN HALF OF THE
CWA...AND THAT LINE SHOULD WEAKEN AS IT CONTINUES TO TRACK EAST.
BEHIND THAT LINE IS A BREAK IN THE PRECIP...AS THERE IS ANOTHER
LINE OF TSTMS BACK OVER CENTRAL PA. HOWEVER...THOSE STORMS SHOULD
WEAKEN BEFORE THEY MAKE IT TO THE LOCAL AREA DUE TO THE LOSS OF
DIURNAL HEATING. ALTHOUGH THERE WILL BE A LOSS OF TSTMS...SHOWERS
WILL OVERSPREAD FROM WEST TO EAST. WILL BUMP UP POPS OVER EASTERN
ZONES IN RESPONSE.
AFTER MIDNIGHT...LOW LEVEL MOISTURE TRAPPED BENEATH FRONTAL
INVERSION WILL LEAD TO PATCHY LIGHT RAIN/DRIZZLE/FOG ESPECIALLY
IN COASTAL/EASTERN SECTIONS. LOWS TONIGHT ARE A GUIDANCE
BLEND...WITH 50-55 IN NYC METRO...AND MAINLY 45-50 ELSEWHERE.
&&
.SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/...
THE COOL MARITIME AIR REALLY COMES IN ON THURSDAY IN THE WAKE OF
THE BACK DOOR COLD FRONT..WITH TEMPS NOT RISING MUCH AND REMAINING
IN THE 50S. ONSHORE FLOW SUGGESTS AT LEAST THE CHC FOR LIGHT RAIN
OR DRIZZLE...THEN STEADIER RAIN SHOULD ARRIVE FROM LATE DAY THU
INTO THU NIGHT AS OVERRUNNING SETS UP AS THE FRONT RETURNS SLOWLY
BACK N AS A WARM FRONT. CHARACTERIZED PRECIP AS SHOWERY AFTER
MIDNIGHT THU NIGHT AS MID LEVEL STABILITY DECREASES.
TEMPS SHOULD DROP INTO THE UPPER 30S AND 40S VIA CAD NORTH OF
APPROACHING WARM FRONT AND INCREASING E FLOW...WHICH SHOULD GUST
AS HIGH AS 30 MPH LATE THU NIGHT ALONG THE COAST.
&&
.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
MODELS IN DECENT AGREEMENT WITH A BROAD UPPER LOW OVER EASTERN
CANADA SLIDING INTO THE NORTH ATLANTIC ON FRIDAY...WHILE AN INTENSE
CENTRAL PLAINS UPPER LOW LIFTS INTO THE GREAT LAKES. THIS WILL HAVE
A STRONG FRONTAL SYSTEM IMPACTING THE REGION ON FRIDAY.
SUBTLE DIFFERENCES CONTINUE WITH SURFACE FEATURES THIS APPROACHING
FRONTAL SYSTEM. IN GENERAL...EXPECTING PRIMARY LOW PRESSURE TO TRACK
ENE THROUGH THE GREAT LAKES...WHILE A TRIPLE POINT LOW DEVELOPS TO
OUR SW AND TRACKS NE...OVER OR JUST SOUTH OF THE AREA FRIDAY
AFT/EVE. LIGHT WAA PCPN IS EXPECTED TO BEGIN THURSDAY NIGHT...AND
THEN A PERIOD OF MODERATE TO HEAVY RAIN IS EXPECTED FRIDAY AS THE
BEST LIFT/ MOISTURE AXIS (50-60 KT LLJ / 2+ STD ABOVE NORMAL PWATS)
WORKS THROUGH THE REGION. EASTERLY 20 TO 30 MPH WINDS WITH GUSTS
INTO THE MID 30S LIKELY FRI MORNING ALONG THE COAST.
A GREATER PROPORTION OF THE OPERATIONAL MODELS AND ENSEMBLE MEANS
ARE POINTING TOWARDS THE TRIPLE POINT LOW TRACKING JUST SOUTH/OR
OVER FAR SOUTHERN PORTIONS OF THE REGION. THIS WOULD RESULT IN
MAINLY A STRATIFORM RAIN EVENT WITH SHORTWAVE ENERGY/MARGINAL
INSTABILITY ALOFT PRESENTING AN ISOLATED ELEVATED TSTM RISK. VARIOUS
ENSEMBLE MEMBERS ARE STILL SIGNALING A TRACK SLIGHTLY FARTHER NORTH
ACROSS THE REGION THOUGH...WHICH WOULD ALLOW FOR AT LEAST SOUTHERN
PORTIONS OF THE REGION TO GET WARM SECTORED. THIS WOULD RESULT IN
MORE CONVECTIVE RAINS AND INCREASE THE THREAT FOR STRONGER LOW TOP
CONVECTION WORKING INTO THESE PORTIONS OF THE REGION.
WITH GREATER CONSENSUS OVER THE PAST FEW DAYS ON THE FURTHER SOUTH
TRACK...WILL MAINTAIN FORECAST CONTINUITY OF WARMER TEMPS AND
ISOLATED TSTM THREAT RELEGATED TO SOUTHERN ZONES. THESE AREAS WILL
HAVE THE BEST CHANCE OF GETTING WARM SECTORED OR BEING MARGINALLY
UNSTABLE ALOFT ON THE COOL SIDE. WHILE NORTHERN
ZONES LINGER ON THE COOL SIDE OF THE FRONT WITH PRIMARILY
STRATIFORM RAIN.
SEE COASTAL FLOOD AND HYDROLOGY SECTION FOR DETAILS ON THE
RESPECTIVE MINOR FLOODING CONCERNS.
THE SHORTWAVE AXIS AND TRIPLE PT LOW/OCCLUDED FRONT GRADUALLY PUSH
EAST FRIDAY NIGHT...WITH DRYING CONDS IN ITS WAKE.
MODELS COMING INTO BETTER AGREEMENT WITH THE EVOLUTION OF THE GREAT
LAKES UPPER LOW THIS WEEKEND AS IT DRIFTS NE THROUGH SE CANADA.
OVERALL APPEARS THAT DRY WEATHER AND SLIGHTLY BELOW SEASONABLE
WEATHER IS EXPECTED FOR THE WEEKEND. A SHORTWAVE TROUGH/COLD FRONT
APPROACH LATE SAT. THIS WILL LIKELY BRING SOME INSTABILITY CU AND
EVEN SOME ISOLATED SHOWERS. DRIER CONDS ARE LIKELY ON SUNDAY AS HIGH
PRES BUILDS IN FROM THE WEST...WITH BREEZY AND COOL CONDS IN THE
WAKE OF THE COLD FRONT.
MODELS ARE SIGNALING AN ACTIVE SPRING PATTERN WITH A ZONAL TO WEAK
RIDGED UPPER PATTERN FOR EARLY NEXT WEEK. THIS IS A LOW CONFIDENCE
FORECAST IN TERMS OF POPS AND TEMPS AT THIS POINT...WHICH WILL BE
BASED ON POSITION OF A STATIONARY BOUNDARY AND TIMING OF WAVES
TRACKING EAST ALONG IT.
&&
.AVIATION /23Z WEDNESDAY THROUGH MONDAY/...
A FRONTAL BOUNDARY REMAINS IN THE VICINITY WITH WEAK WAVES OF LOW
PRESSURE RIDING ALONG IT INTO THIS EVENING. THE FRONT MOVES
SLIGHTLY SOUTH TONIGHT INTO THURSDAY AS WEAK HIGH PRESSURE BUILDS
IN FROM THE NORTH AND WEST.
VFR BUT CONDITIONS DETERIORATE WITH ONSET OF SHRA/TSRA MAINLY
BETWEEN 23-03Z. MVFR TO LOCALIZED IFR WILL BE POSSIBLE AS WELL AS
GUSTY WINDS OF 30 KT. A FEW SHOWERS COULD LINGER BEYOND INTO
OVERNIGHT. GUSTS COULD BE POSSIBLY HIGHER. TIMING OF TSRA COULD VARY
BY 1-2 HOURS.
SE-S WINDS BECOME MORE NORTHERLY TONIGHT AND BACK EASTERLY ON
THURSDAY. WIND SPEED AROUND 10 KT OR LESS. MVFR CONDITIONS WILL
PERSIST WITH IFR POSSIBLE AT TIMES ON THURSDAY IN LIGHT
RAIN/DRIZZLE.

QUIET WINDS/SEAS THROUGH THU AS WEAK LOW PRESSURE MOVES ACROSS.
CANNOT TOTALLY RULE OUT OCEAN SEAS OUT EAST REACHING 5 FT AT SOME
POINT LATE TONIGHT OR EARLY THU MORNING...BUT CONFIDENCE TOO LOW
TO WARRANT SCA. SHOWERS/TSTMS WILL MOVE ACROSS THE WATERS THIS
EVENING...AND THEN SHOWERS ARE EXPECTED AFTER MIDNIGHT.
CONFIDENCE HIGHER IN INCREASING E FLOW THU NIGHT BETWEEN WARM
FRONT TO THE SOUTH AND INLAND HIGH PRESSURE OVER NEW ENGLAND...
WITH GALES LOOKING LIKELY ENOUGH FOR LATE THU NIGHT INTO FRI
MORNING TO WARRANT GALE WATCH. SCA CONDS ARE LIKELY TO DEVELOP ON
THE HARBOR/SOUND/BAYS AT THAT TIME AS WELL...WITH SEAS BUILDING
TOWARD 10 FT ON THE OCEAN...AND 3-5 FT ON LONG ISLAND SOUND.
THEREAFTER THERE IS SOME SOME UNCERTAINTY ON THE TRACK OF TRIPLE
POINT LOW PRESSURE AND WARM FRONT ON FRIDAY...WHICH WOULD AFFECT
WHERE/WHEN WINDS SHIFT TO THE SOUTH AND WHEN THERE MIGHT BE A
LULL. WARM ADVECTION FOG BECOMES A POSSIBILITY FOR AREAS THAT
GET WARM SECTORED...PARTICULARLY THE OCEAN WATERS.
SUB SCA CONDS EXPECTED FRI NIGHT INTO THE WEEKEND AS HIGH PRESSURE
BEGINS TO BUILD IN THE WAKE OF THE DEPARTING FRONTAL SYSTEM.
SOUTHERLY SWELLS WILL LIKELY KEEP OCEAN SEAS SCA UNTIL
SAT NIGHT/SUNDAY.
&&
.HYDROLOGY...
SHOWERS AND SCT TSTMS THIS EVENING COULD BRING BASIN AVG QPF OF
1/4 TO 1/2 INCH. LOCALLY HIGHER AMTS CLOSER TO 1 INCH COULD OCCUR
MAINLY OVER NE NJ.
SIGNIFICANT RAINFALL OF 1 TO 1 1/2 INCHES IS EXPECTED ON AVERAGE ON
FRIDAY. MINOR URBAN AND POOR DRAINAGE PONDING IS LIKELY. BASED ON
AROUND 2 INCH FFG IN 6-12 HR ACROSS NE NJ...THERE IS SMALL CHANCE
FOR FLASHY SMALL STREAM FLOODING THERE. MMEFS ENSEMBLE RIVER
GUIDANCE DOES NOT INDICATE WE REACH MINOR FLOOD THRESHOLDS FOR
ANY OF OUR FORECAST POINTS.
&&
.TIDES/COASTAL FLOODING...
THE COASTAL FLOOD THREAT REMAINS LOW FOR THE FRIDAY MORNING HIGH
TIDE. STORM SURGE OF AROUND 2 TO 2 1/2 FT WOULD BE NEEDED FOR
MINOR COASTAL FLOODING DURING THE FRI MORNING/EARLY AFTERNOON HIGH
TIDE. WORST CASE SCENARIO WOULD BE IF BORDERLINE GALE EASTERLY
WINDS CONTINUE THROUGH THE TIME OF HIGH TIDE FRI
MORNING/AFTERNOON...THREATENING SOME LOCALIZED MINOR FLOODING
ACROSS VULNERABLE LOW LYING AREAS OF THE WESTERN SOUTH SHORE
BAYS...WESTERN LONG ISLAND SOUND...AND PECONIC BAY.
