AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE NEW YORK NY
1116 PM EDT WED MAR 31 2010
.SYNOPSIS...
LOW PRESSURE WILL TRACK WELL TO THE EAST...ALLOWING HIGH PRESSURE TO
BUILD IN THROUGH SATURDAY. A WEAK COLD FRONT CROSSES THE AREA
ON SUNDAY...FOLLOWED BY HIGH PRESSURE EARLY NEXT WEEK. A STORM
SYSTEM APPROACHES FROM THE WEST MID WEEK.
&&
.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
DRY WEATHER TONIGHT AS LOW PRES MOVES FURTHER OUT TO SEA AND A
RIDGE OF HIGH PRES BUILDS IN. GRADUAL CLEARING OVERNIGHT FROM WEST
TO EAST WITH LIGHTENING WINDS. FOLLOWED A MAV/MET/LAV BLEND FOR
TEMP TRENDS.
&&
.SHORT TERM /6 AM THURSDAY MORNING THROUGH SATURDAY/...
AREA WILL BE SANDWICHED BETWEEN WESTERN TROUGH THAT WILL TRAVERSE
ACROSS ROCKIES AND THROUGH THE MID WEST...AND CUTOFF LOW OVER THE
ATLANTIC. RIDGE BUILDS ACROSS THE EASTERN SEABOARD AS IT GETS
SQUEEZED IN TIME. MODELS ARE IN GENERAL AGREEMENT WITH MAJOR
FEATURES THROUGH THIS TIME FRAME WITH SFC HIGH PRESSURE BUILDING
OVER THE AREA INITIALLY...THEN PASSING JUST TO THE EAST RESULTING
IN PERSISTENT ONSHORE FLOW. AS MENTIONED...HEIGHTS RISE ALOFT AS
RIDGE BUILDS BETWEEN TWO SYSTEMS. WARMER WEATHER THE
RESULT...MAINLY ACROSS THE INTERIOR AWAY FROM ANY WATER
INFLUENCES. SHOULD BE A SHARP GRADIENT IN TEMPS FROM NW ZONES AND
ERN LI THROUGH SATURDAY. FOLLOWED A MOS BLEND...BUT LEANED TOWARD
WARMER MAVS FOR DAYTIME HIGHS. INCREASE S/SE FLOW HAS ME CONCERNED
ON SATURDAY...AS COOLER AIR SHOULD EVEN PENETRATE FAR INTERIOR ZONES.
OTHERWISE...DRY THROUGH THE PERIOD WITH PLENTY OF SUNSHINE. WILL
NEED TO KEEP AN EYE ON ANY NIGHTTIME MARINE STRATUS...ESPECIALLY
FRIDAY AND SATURDAY AS ONSHORE FLOW PERSISTS...AND COOLER AND
PROGRESSIVELY MORE MOIST AIR GETS TRAPPED UNDERNEATH STRENGTHENING
INVERSION.
&&
.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
MILD WX IS SHAPING UP FOR MOST OF THIS PERIOD...FIRST VIA AN EXITING
UPPER RIDGE OVER THE AREA...THEN VIA ZONAL FLOW MON-TUE IN ITS
WAKE...AND ANOTHER BUILDING UPPER RIDGE BY MID WEEK AHEAD OF A STORM
SYSTEM IN THE PLAINS STATES. PRETTY CLEAR SIGNAL FOR LOW STRATUS
EXISTS SAT NIGHT INTO SUN MORNING..WITH ONSHORE FLOW OFF THE COLD
OCEAN AND WAA JUST OFF THE DECK SHARPENING A LOW LEVEL INVERSION...
BUT THEN WITH SOME AFTERNOON CLEARING TEMPS SHOULD RISE INTO THE
LOWER AND MID 70S INLAND...AND REMAIN IN THE 60S NEAR SOUTH FACING
SHORELINES.
A WEAK COLD FRONT WILL PASS THROUGH DURING SUNDAY AFTERNOON AND
EARLY EVENING...WITH ONLY SLIGHT CHANCE POP AT BEST MAINLY FROM NYC
NORTH/WEST AS GFS FORECASTS SOME SFC-BASED INSTABILITY AHEAD OF THE
FRONT. POST-FRONTAL DOWNSLOPE FLOW SHOULD MAKE MON NEARLY AS
MILD...EVEN IN COASTAL SECTIONS BEFORE AN AFTERNOON SEA BREEZE TAKES
HOLD. SLIGHTLY COOLER ON TUE...WITH HIGHS IN THE 60S TO NEAR 70 WITH
SOUTHERLY FLOW...ALSO INCREASING CLOUDS AND SLIGHT CHANCE POP AHEAD
OF AN APPROACHING WARM FRONT...THEN CHANCE POP TUE NIGHT AS THE
FRONT MOVES THROUGH.
HAVE FORECAST AREA TO GET INTO THE WARM SECTOR ON WED...WITH TEMPS
IN THE 70S INLAND AND 60S AT THE COAST AS UPPER RIDGE BUILDS OVER
THE AREA AHEAD OF A STORM SYSTEM IN THE PLAINS. THE 00Z ECMWF... THE
MAIN PIECE OF MEDIUM RANGE GUIDANCE IN CONFLICT WITH THIS IDEA...
LOOKS TOO STRONG IN ITS DEVELOPMENT OF LOW PRESSURE PASSING WELL TO
THE NORTH DURING MID WEEK...WHICH WOULD MAINTAIN MID LEVEL
CONFLUENCE OVER NEW ENGLAND AND AN EXTENSION OF SFC RIDGING BUILDING
SE FROM QUEBEC...KEEPING THE FRONT JUST TO THE SW...AND SO HAVE
SIDED WITH WARMER GUIDANCE.
&&
.AVIATION /01Z THURSDAY THROUGH MONDAY/...
LOW PRESSURE OVER THE WESTERN ATLANTIC WILL CONTINUE TO MOVE OUT
TO SEA TONIGHT AS A RIDGE OF HIGH PRES BUILDS IN FROM THE WEST.
FORECAST IS A LITTLE BIT OF A CHALLENGE TONIGHT AS MODEL GUIDANCE
KEEPS LOW LEVEL MOISTURE ACROSS THE AREA FOR A GOOD PART OF THE
NIGHT. HIGH MVFR TO LOW VFR CIGS REMAIN EAST OF NYC TERMS AND THE
POTENTIAL REMAINS FOR LOWERING CIGS OVERNIGHT. HOWEVER...MODEL
GUIDANCE ALSO INDICATES A DECREASE IN MOISTURE LEVELS AS THE NIGHT
WEARS ON...SO COULD END UP SCT INSTEAD OF BKN. HAVE KEPT NYC TERMS
VFR THROUGH THE NIGHT...BUT THERE IS A CHC THEY DO LOWER TO MVFR.
LIGHT NORTHERLY WINDS (LESS THAN 10 KT) OVERNIGHT...COULD LEAD TO
SOME PATCHY FOG (MVFR) WITH RESIDUAL GROUND MOISTURE. SEABREEZES
EXPECTED AT ALL COASTAL TERMINALS THU...TIMING MAY BE OFF A FEW
HOURS.
ANY LINGERING MVFR WILL IMPROVE TO VFR BY 12-14Z.

.MARINE...
WEAKENING LOW PRESSURE WILL CONTINUE TO MOVE OUT TO SEA TONIGHT. SEAS
ON ANZ355 REMAIN BETWEEN 5 AND 7 FT DUE TO A CONTINUING SE SWELL.
HAVE EXTENDED THE SCA HERE THROUGH THE NIGHT (IN LINE WITH
REMAINING OCEAN ZONES)...ALTHOUGH THEY MAY SUBSIDE BEFORE THEN.
RETURN FLOW COMMENCES LATER THURSDAY THROUGH SATURDAY AS HIGH
PRESSURE PASSES EAST OF THE WATERS.
WHILE FRIDAY INTO THE SATURDAY MAY BE GREAT ON LAND...MARINE
STRATUS AND FOG COULD BE A CONCERN...ESPECIALLY IN THE EARLY
MORNING HOURS.
QUIET FROM SAT NIGHT-MON NIGHT...WITH S-SW FLOW BEFORE A COLD
FRONTAL PASSAGE SUNDAY EVENING...FOLLOWED BY W FLOW LATER SUNDAY
NIGHT INTO MON AS WEAK HIGH PRESSURE BUILDS IN.
&&
.HYDROLOGY...
AS WATER LEVELS ACROSS THE YANTIC RIVER BASIN CONTINUE TO
RECEDE...THE WARNING WAS DROPPED THIS AFTERNOON. THERE STILL IS A
GOOD AMOUNT OF RESIDUAL FLOODING ACROSS THE AREA AS A FEW RIVERS AND
STREAMS CONTINUE TO RISE AS A RESULT OF RUNOFF FROM THE HEAVY RAINS
FOR THE PAST TWO DAYS. THE AREA FLOOD WARNING ACROSS NEW LONDON WILL
CONTINUE THROUGH TONIGHT OR EVEN THROUGH THURSDAY MORNING.
WITH DRY WEATHER EXPECTED THE REMAINDER OF THE WEEK...RIVERS AND
STREAMS WILL CONTINUE TO RECEDE.
&&
.TIDES/COASTAL FLOODING...
ANOMALIES ARE EXPECTED TO RUN AROUND 1/2 A FOOT ABOVE NORMAL
TONIGHT. VERY SMALL DEPARTURES ARE NEEDED TO REACH MINOR COASTAL
FLOODING BENCHMARKS...UNDER A FOOT...DUE TO HIGH ASTRONOMICAL TIDES.
DO FEEL LOCATIONS ALONG THE SOUTH SHORE BAYS OF LONG ISLAND AND THE
WESTERN PORTION OF THE LONG ISLAND SOUND WILL APPROACH MINOR CSTL
FLOODING BENCHMARKS. HOWEVER...I ONLY EXPECT A FEW LOCATIONS TOUCH OR
GO JUST OVER THESE BENCHMARKS. A COASTAL FLOOD STATEMENT HAS BEEN
ISSUED TO ADDRESS THIS FOR THE NEXT HIGH TIDE CYCLE.
