AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
456 PM EDT TUE MAR 17 2015
.SYNOPSIS...
DEEPENING LOW PRESSURE EAST OF NEW ENGLAND THIS EVENING WILL LIFT
UP INTO THE CANADIAN MARITIMES OVER THE NEXT SEVERAL DAYS...WHILE
HIGH PRESSURE BUILDS EAST FROM THE UPPER MIDWEST. A COASTAL LOW
PRESSURE SYSTEM MAY IMPACT THE AREA FRIDAY INTO FRIDAY NIGHT...
FOLLOWED BY A COLD FRONTAL PASSAGE LATE SATURDAY. HIGH PRESSURE
BUILDS TOWARDS THE REGION FROM THE GREAT LAKES SUNDAY INTO EARLY
NEXT WEEK.
&&
.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
STRONG COLD ADVECTION AND A GUSTY NW FLOW WILL CONTINUE INTO THE
NIGHTTIME HOURS AS LOW PRESSURE RAPIDLY DEEPENS EAST OF NEW
ENGLAND AND HIGH PRESSURE BUILDS EAST FROM THE UPPER MIDWEST.
GUSTS UP TO 40 MPH THE FIRST PART OF THE EVENING WILL GRADUALLY
DIMINISH OVERNIGHT. THERE WILL ALSO BE SOME INSTABILITY CU THAT
SHOULD DISSIPATE AS WELL.
LOWS TONIGHT WILL BE WELL BELOW NORMAL...RANGING FROM UPPER TEENS
TO AROUND 20 INLAND...LOWER TO MID 20S AT THE COAST...EXCEPT MID
TO UPPER 20S IN THE NYC METRO. THIS IS ABOUT 10 DEGREES BELOW
NORMAL.
&&
.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/...
A NEGATIVELY TILTED UPPER TROF STRETCHING FROM HUDSON BAY SE INTO
NORTHERN NEW ENGLAND WILL ALLOW WINTER TO HOLD ON THROUGH THE END
OF THE WEEK WITH UNSEASONABLY COLD AIR. DAYTIME HIGHS ON WED WILL
BE MAINLY IN THE MID TO UPPER 30S...BUT LOWER 40S NYC METRO.
NORMAL HIGHS ARE ABOUT 45 TO 50.
IN ADDITION...A GUSTY NW FLOW WILL CONTINUE...BUT NOT QUITE AS
STRONG AS TUE. GUSTS UP TO 35 MPH ARE EXPECTED ALONG WITH A FEW
INSTABILITY CU.
SKIES CLEAR OUT WED NIGHT WITH LOWS IN THE TEENS TO LOWER 20S.
GUSTY NW WINDS AT THE ONSET WILL DIMINISH OVERNIGHT.
&&
.LONG TERM /THURSDAY THROUGH TUESDAY/...
NOT A TREMENDOUS AMOUNT OF AGREEMENT BETWEEN THE GFS AND ECMWF WITH
SOME DIFFERENCES FOR THE FIRST HALF OF THE LONG TERM PERIOD...BEFORE
THEIR SOLUTIONS DIVERGE QUITE DRAMATICALLY EARLY NEXT WEEK. WILL
LEAN TOWARD THE ECMWF FOR NOW...WITH A BETTER RUN TO RUN
CONSISTENCY...PARTICULARLY FOR THE LATTER PART OF THE FORECAST
PERIOD NEXT WEEK. HIGH PRESSURE WILL BUILD ACROSS THE AREA ON
THURSDAY AND CONTINUE TO DRIFT EAST THURSDAY NIGHT...AS A WAVE OF
LOW PRESSURE DEVELOPS OVER THE SOUTHEAST AND PUSHES TOWARD THE AREA
ON FRIDAY. THE MODELS DIFFER WITH THE TRACK OF THIS LOW ON
FRIDAY...WITH THE ECMWF JUST SOUTH AND EAST OF NEW YORK CITY AND
LONG ISLAND AND THE GFS MUCH FURTHER SOUTH AND EAST. EITHER
WAY...COLDER TEMPERATURES WILL BE IN PLACE AND IT APPEARS THAT WE
COULD SEE SOME SNOW AT THE ONSET...EVEN AT THE COAST. THE ECMWF
WOULD ALLOW WARMER AIR TO WRAP INTO THE REGION ALLOWING FOR A
CONVERSION TO A MIX OF SNOW AND RAIN...OR PERHAPS A COMPLETE
CHANGEOVER. MEANWHILE..THE GFS WILL KEEP US COLDER...BUT POTENTIALLY
TRACK THE LOW FAR ENOUGH SOUTH AND EAST TO KEEP THE MAIN AREA OF
PRECIPITATION FROM REACHING THE LOCAL AREA.
THEREAFTER...A GENERAL TROUGH ALOFT WILL KEEP SATURDAY COLD..CLOUDY
AND DAMP BEFORE A COLD FRONT APPROACHES AND PUSHES THROUGH ON
SUNDAY. HERE IS WHERE THE MODEL SOLUTIONS REALLY DIVERGE. THE GFS
WANTS TO DEVELOP A CLOSED LOW WITH THE NEXT WAVE OF ENERGY TRAVELING
DOWN THE BACKSIDE OF THE TROUGH NEAR THE MID-ATLANTIC COAST BY THE
MIDDLE OF NEXT WEEK. MEANWHILE...THE ECMWF KEEPS THE PATTERN
PROGRESSIVE. THE GFS SOLUTION IS A SIGNIFICANT CHANGE FROM PRIOR
RUNS...SO HAVE LEANED HEAVILY TOWARD THE ECMWF DUE TO ITS RUN TO RUN
CONSISTENCY. THIS CALLS FOR A STRONG AREA OF HIGH PRESSURE TO BUILD
INTO THE AREA BEHIND THE COLD FRONTAL PASSAGE ON SUNDAY AND REMAIN
IN CONTROL THROUGH THE MIDDLE OF NEXT WEEK.
TEMPERATURES WILL GENERALLY REMAIN BELOW NORMAL FOR VIRTUALLY ALL OF
THE FORECAST PERIOD. THE ONLY EXCEPTION MAY BE BRIEFLY ON SATURDAY
AS TEMPERATURES WARM UP PRIOR TO THE COLD FRONT ON SUNDAY.
&&
.AVIATION /21Z TUESDAY THROUGH SUNDAY/...

PRESSURE BUILDS FROM THE WEST WEDNESDAY.

.MARINE...
GALE WARNING REMAINS IN EFFECT FOR ALL WATERS THROUGH THE EARLY
MORNING HOURS WED. SCA CONDITIONS WILL THEN FOLLOW THROUGH THE
FIRST HALF OF WED NIGHT. THE STRONG NW FLOW IS DUE TO DEEPENING
LOW PRESSURE OVER THE CANADIAN MARITIMES COMBINED WITH STRONG HIGH
PRESSURE BUILDING EAST FROM THE MID SECTION OF THE COUNTRY.
HIGH PRESSURE WILL INITIALLY BE OVER THE AREA ON THURSDAY BEFORE
GIVING WAY TO A DEVELOPING LOW PRESSURE SYSTEM ON FRIDAY AND FRIDAY
NIGHT. WINDS AND SEAS WILL INCREASE AS A RESULT...BUT SHOULD STAY
BELOW SCA CRITERIA. A COLD FRONT WILL PUSH ACROSS THE AREA ON
SUNDAY AND SHOULD RESULT IN WINDS AND SEAS NEAR SCA CRITERIA ON THE
OCEAN WATERS LATE THIS WEEKEND AND THE START OF NEXT WEEK.
&&
.HYDROLOGY...
THE POTENTIAL EXISTS FOR 1/2 TO 1 INCH OF LIQUID EQUIVALENT ON
FRIDAY INTO FRIDAY NIGHT. SOME OF THIS MAY FALL IN THE FROZEN STATE
AT THE ONSET...ESPECIALLY ACROSS INLAND SECTIONS.
RECENT INCREASED FLOW ON RIVERS/STREAMS...PARTICULARLY ACROSS THE
LOWER HUDSON VALLEY AND SOUTHERN CT...COUPLED WITH MILD
TEMPERATURES...MAY CAUSE ICE BREAKUP/MOVEMENT INTO EARLY THIS

ICE JAM FLOODING IS UNPREDICTABLE AND SUDDEN...SO INTERESTS ALONG
ICE COVERED RIVERS SHOULD MONITOR NWS FORECASTS FOR THE LATEST
INFORMATION.
