NATIONAL WEATHER SERVICE NEW YORK NY
439 AM EST MON DEC 17 2012

.SYNOPSIS...
AS ONE AREA OF LOW PRESSURE TO OUR SOUTHEAST SHIFTS FARTHER OFFSHORE
TODAY...ANOTHER AREA OF LOW PRESSURE APPROACHES FROM THE WEST. THIS
LOW PRESSURE SYSTEM WILL PASS JUST TO OUR NORTH ON TUESDAY AND DRAG
A COLD FRONT ACROSS THE REGION. THIS LOW THEN TRACKS FROM NEAR
CAPE COD TUESDAY EVENING INTO THE CANADIAN MARITIMES BY WEDNESDAY
AFTERNOON. HIGH PRESSURE BUILDS DOWN FROM SOUTHEASTERN CANADA
WEDNESDAY NIGHT...THEN SLOWLY RETREATS TO THE NORTHEAST THURSDAY
AND THURSDAY NIGHT. A POTENT STORM SYSTEM MOVES INTO THE EASTERN
GREAT LAKES THURSDAY NIGHT...THEN TRACKS TO OUR NORTH
FRIDAY...DRAGGING ITS OCCLUDED FRONT THROUGH THE REGION. THIS LOW
THEN MEANDERS ACROSS NORTHERN NEW ENGLAND AND THE WESTERN CANADIAN
MARITIMES INTO SUNDAY.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
MAIN BATCH OF RAINFALL EXITS TO THE EAST EARLY THIS MORNING. BEHIND
IT...NOT AS MUCH MOISTURE...AND NOT A LOT OF LIFT TO HELP SQUEEZE
OUT MORE RAIN...BUT ENOUGH FOR A MENTION OF PATCHY FOG AND DRIZZLE.
IN SPITE OF A CLOUDY DAY...HIGH TEMPERATURES WILL AVERAGE ABOUT 5 TO
10 DEGREES ABOVE NORMAL.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM TUESDAY/...
LOW PRESSURE APPROACHING FROM THE WEST BRINGS MORE RAIN TO THE
FORECAST AREA TONIGHT. BY MIDNIGHT...IT SHOULD BE RAINING OVER MOST
OF THE AREA IF NOT ALL OF IT. RAIN WILL SPREAD GENERALLY WEST TO
EAST. WITH TEMPERATURES REMAINING ABOVE FREEZING...NO WINTRY
PRECIPITATION EXPECTED.

IT LOOKS LIKE THE CENTER OF THE LOW PRESSURE SYSTEM WILL BE PASSING
TO OUR NORTH ON TUESDAY. THIS WILL THEN RESULT IN A COLD FRONT
MOVING THROUGH THE REGION MAINLY DURING THE AFTERNOON. RAIN WILL
STILL BE LIKELY IN MOST SPOTS...THEN JUST A CHANCE OF AFTERNOON
SHOWERS. WINDS WILL INCREASE AS WELL...SO TURNING BREEZY FOR SOME
AREAS BY LATE. IT WILL BE A MILD DAY...WITH HIGH TEMPERATURES 10 TO
15 DEGREES ABOVE NORMAL.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...
GOOD OVERALL AGREEMENT BETWEEN THE MODELS IN THIS TIME FRAME...WITH
MINOR DIFFERENCES IN TRACK/TIMING...THAT ARE CLOSE ENOUGH TO BEST
HANDLE WITH A BLEND. USED A NAM/SREF/GFS/ECMWF BLEND TUESDAY
NIGHT-WEDNESDAY NIGHT...THEN A GFS/ECMWF BLEND THURSDAY-SUNDAY.

A CUTOFF LOW TRACKS TO OUR N TUESDAY NIGHT THEN SLOWLY MOVES EAST
INTO THE CANADIAN MARITIMES WEDNESDAY. EXPECT ANY LINGERING RAIN
SHOWERS TO TAPPER OFF FROM SW TO NE TUESDAY NIGHT...THEN WEDNESDAY
DRY W/ STRONG LOW LEVEL NW FLOW. GUSTY WINDS EXPECTED TUESDAY NIGHT
INTO WEDNESDAY...WITH 950-850 WINDS FORECAST 30-45 KT WITH LOW LEVEL
MIXING NEAR TO AT DRY ADIABATIC...ESPECIALLY DURING THE DAY ON
WEDNESDAY. FOR NOW APPEARS WINDS WILL BE SUB-ADVISORY.

DEEP LAYERED RIDGING BUILDS OVER THE TRI-STATE WEDNESDAY
NIGHT...THEN SLIDES TO OUR EAST THURSDAY. APPEARS TO BE SUFFICIENT
ISENTROPIC ASCENT BY THURSDAY AFTERNOON TO WARRANT CHANCE POPS OVER
NW 1/5 OF THE CWA.

A POTENT CUTOFF LOW TRACKS INTO THE EASTERN GREAT LAKES THURSDAY
NIGHT...THEN INTO EASTERN UPSTATE NY/SOUTHERN QUEBEC FRIDAY. THIS IS
A COMPROMISE BETWEEN THE SLIGHTLY SLOWER/FARTHER S ECMWF AND
SLIGHTLY FASTER/FARTHER N GFS.

HAVE THE POTENTIAL FOR SIGNIFICANT RAINFALL AND GUSTY WINDS FROM
THIS SYSTEM WITH 50-60 KT LOW LEVEL JET AHEAD OF IT THURSDAY NIGHT
INTO FRIDAY MORNING...AND POTENTIALLY INTO FRIDAY AFTERNOON OVER FAR
EASTERN ZONES.

IN THE WAKE OF THIS SYSTEM IS IT SLOWLY MEANDERS FROM NORTHERN NEW
ENGLAND FRIDAY NIGHT...ULTIMATELY TOWARDS NOVA SCOTIA BY LATE
SUNDAY...THE REGION WILL EXPERIENCE MUCH COLDER WEATHER WITH 850
TEMPERATURES FORECAST DOWN TO -10C BY SATURDAY AND CONTINUING
THROUGH SUNDAY WITH GUSTY WNW-NW WINDS. GIVEN PROXIMITY OF UPPER LOW
AND LAKE EFFECT TRAJECTORY/SET UP HAVE SLIGHT CHANCE POPS IN FRIDAY
NIGHT-SUNDAY...WITH MAINLY ISOLD SNOW SHOWERS ACROSS THE INTERIOR
AND ISOLD RAIN/SNOW SHOWERS NEAR THE COAST.

FOR TEMPERATURES TUESDAY NIGHT-SUNDAY...
FOR LOWS TUESDAY NIGHT USED A BLEND OF MAV/MET GUIDANCE WITH NAM
2-METER TEMPERATURES WITH VALUES 5-10 DEGREES ABOVE NORMAL. FOR
HIGHS WEDNESDAY USED A BLEND OF MAV/MET GUIDANCE WITH NAM 2-METER
TEMPERATURES AND A MIX DOWN FROM 900 HPA PER BUFKIT
SOUNDINGS...FORECASTING VALUES A LITTLE OVER 5 DEGREES ABOVE NORMAL.

USED A BLEND OF MEX/MEX ENSEMBLE MEAN/ECE GUIDANCE WITH NAM 2-METER
TEMPERATURES FOR LOWS WEDNESDAY NIGHT - WITH READINGS FORECAST
AROUND 5 DEGREES ABOVE NORMAL.

FORM THURSDAY-SUNDAY USED A BLEND OF MEX/MEX ENSEMBLE MEAN/ECE/HPC
GUIDANCE...WITH TEMPERATURES STARTING OUT AROUND 10 DEGREES ABOVE
NORMAL THURSDAY/THURSDAY NIGHT...AROUND 5 DEGREES ABOVE NORMAL
FRIDAY/FRIDAY NIGHT...NEAR NORMAL SATURDAY/SATURDAY NIGHT...THEN
BELOW NORMAL ON SUNDAY.

&&

.AVIATION /09Z MONDAY THROUGH FRIDAY/...
A WAVE OF LOW PRESSURE SOUTH OF LONG ISLAND MOVES WELL OFFSHORE
SOUTHEAST OF LONG ISLAND BY MORNING. WEAK RIDGE OF HIGH PRESSURE
THEN BUILDS IN FROM THE NORTH AND WEAKENS BY AFTERNOON AS THE NEXT
LOW PRESSURE SYSTEM APPROACHES FROM THE WEST.

NORTHEAST WINDS REMAIN GUSTY...UP TO 20 KT...ON LONG ISLAND...BUT
IT HAS COOLED ENOUGH ELSEWHERE TO KEEP THE GUSTS FROM MIXING DOWN.
SUSTAINED WINDS ALSO RANGING BETWEEN 10 AND 15 KT HERE AS WELL AT
AT KJFK/KLGA AND SHOULD CONTINUE THROUGH 12Z. GUIDANCE NOT
HANDLING THIS WELL...TOO WEAK. WINDS AND GUSTS SHOULD THEN
DECREASE AS THE PRES GRADIENT WEAKENS. ELSEWHERE WINDS WILL REMAIN
LESS THAN 10 KT.

IFR CONDS WILL PREVAIL. ORGANIZED RAIN IS SHIFTING TO THE E...SO
WOULD EXPECT CONDS TO LOWER ONCE STEADY RAIN ENDS. NOT SURE IF
VSBYS WILL DROP...WINDS MAY BE ENOUGH TO KEEP THEM MARGINAL
VFR...BUT EXPECT IFR/LIFR CIGS WITH -DZ. MARGINAL VFR VSBYS WITH
CEILINGS LIKELY REMAINING IFR BY MID MORNING...THERE IS A CHANCE BY
AFTERNOON THAT CEILINGS WILL BECOME MARGINAL VFR. CONFIDENCE IS
LOW ON CIGS FORECAST.

CONDITIONS LOWER ONCE AGAIN AFTER 18/00Z AS RAIN MOVES INTO THE
TERMINALS WITH IFR TO LIFR CEILINGS.
