AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
541 PM EDT MON MAR 18 2013
.SYNOPSIS...
A COASTAL LOW DEVELOPS NEAR THE MID-ATLANTIC COAST TONIGHT AND
TRACKS JUST SOUTH OF LONG ISLAND TUESDAY. AS IT EXITS TOWARDS NEW
ENGLAND TUESDAY NIGHT...WEAK HIGH PRESSURE BUILDS IN BEHIND IT
THROUGH WEDNESDAY.
&&
.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
PCPN WILL SPREAD EAST ACROSS THE TRI STATE AREA TONIGHT. AS A WARM
NOSE ALOFT NEAR 800-850MB BUILDS...PCPN TYPE BECOMES MIXED.
PREFERRED THE COLDER SIDE OF GUIDANCE FOR SURFACE TEMPS...NOTING
DEWPOINTS STARTING OUT IN THE TEENS AND LOW 20S AND THE MAGNITUDE
OF WET-BULBING BASED ON THIS INITIAL DRYNESS. BASED ON THE
EXPECTED MAX TEMP IN THE WARM NOSE AND SURFACE TEMPS...PCPN STARTS
AS SNOW...BUT THEN THE SNOW MIXES WITH SLEET AT SOME POINT
EVERYWHERE. EVENTUALLY...FREEZING RAIN IS EXPECTED FOR MOST OF
CT...THE LOWER HUDSON AND ADJACENT PARTS OF NJ LATE THIS
EVENING/OVERNIGHT. A TRANSITION TO JUST PLAIN RAIN BEGINS NEAR
MIDNIGHT FOR THE CITY AND THE SOUTH COAST OF LONG ISLAND. THE RAIN
LINE THEN SHIFTS NORTH COURTESY OF AN ONSHORE EAST WIND...PUSHING
SLIGHTLY NORTH OF THE CITY BY DAYBREAK.
MODELS ARE IN FAIRLY GOOD AGREEMENT REGARDING THE FORECAST LIQUID
EQUIVALENT PRECIPITATION. BLENDED THE PREVIOUS FORECAST WITH HPC
AND RFC NUMBERS. SO FOR SNOW/SLEET TOTALS BEFORE THE CHANGEOVER TO
FREEZING RAIN AND RAIN...EXPECTING 2 INCHES OR LESS FOR ALL
COASTAL SECTIONS...AND MOSTLY 2 TO 5 INCHES INLAND...BUT UP TO 6
INCHES POSSIBLE FOR THE FAR NW FRINGES OF THE FORECAST AREA. ON
TOP OF THIS...UP TO A TENTH TO A QUARTER OF AN INCH OF ICE ACROSS
SPOTS THAT SEE FREEZING RAIN.
AS SUCH...WINTER WEATHER WARNINGS AND ADVISORIES REMAIN POSTED AS
THEY HAVE BEEN FOR THE COMBINATION OF ICE AND SNOW HAZARDS.
WINDS MAY GUSTS UPWARDS OF 35 TO 40 MPH TONIGHT AS A LOW LEVEL JET
PASSES THROUGH...BUT IT LOOKS LIKE WE'LL FALL SHORT OF ADVISORY
CRITERIA. THE TIME FRAME FOR THE HIGHEST GUSTS APPEARS TO BE A
COUPLE OF HOURS BEFORE AND AFTER MIDNIGHT. RAIN COULD BE HEAVY AT
TIMES DURING THE SAME TIME PERIOD...BUT NOTHING MORE THAN MINOR
FLOODING WOULD BE POSSIBLE. SEE THE HYDROLOGY SECTION BELOW FOR MORE
DETAILS.
&&
.SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/...
LOW PRESSURE CENTER PASSES NOT TOO FAR TO OUR SOUTH MID-MORNING INTO
EARLY AFTERNOON. PCPN CHANCES THEREFORE DROP DURING THE AFTERNOON
WITH THE DEPARTING STORM. THERMAL PROFILES SUPPORT THE CHANCE OF
SOME SNOW ACROSS THE NW ZONES RIGHT AS PCPN BEGINS TO END...SO NOT
LOOKING FOR ANY SIGNIFICANT ADDITIONAL SNOW/SLEET ACCUMULATIONS.
ICING WILL HOWEVER CONTINUE TO BE AN ISSUE PRIMARILY NORTH OF I-95
AND I-287 FOR AT LEAST PART OF THE MORNING COMMUTE. WARNINGS AND
ADVISORIES WILL REMAIN WITH AN EXPIRATION TIME OF 10AM...WHEN TEMPS
SHOULD BE ABOVE FREEZING FOR THESE NORTHERN ZONES. BUT BEFORE THIS
TIME...AN ADDITIONAL LIGHT ICE ACCUMULATION IS EXPECTED.
WITH THE EXCEPTION OF THE FAR NE ZONES WHERE A SLIGHT CHANCE OF
RAIN/SNOW SHOWERS WILL EXIST EARLY...DRY FOR TUESDAY NIGHT. A BLEND
OF THE MAV/NAM MOS LOOKED GOOD FOR LOWS.
&&
.LONG TERM /WEDNESDAY THROUGH MONDAY/...
HIGH PRESSURE BUILDS TO THE SOUTH OF THE AREA ON WEDNESDAY...WHILE
LOW PRESSURE PUSHES NORTHEAST INTO THE CANADIAN MARITIMES. LOW
PRESSURE THEN PASSES OFFSHORE TO THE SOUTHEAST OF THE AREA ON
THURSDAY. HIGH PRESSURE THEN BUILDS INTO THE REGION THROUGH THE
WEEKEND.
.LONG TERM /WEDNESDAY THROUGH MONDAY/...
THE LONG TERM WILL BE CHARACTERIZED BY CONTINUED BELOW NORMAL
TEMPERATURES AND A FEW CHANCES FOR LIGHT WINTRY PRECIP...AS THE
UPPER LOW TO OUR NORTH AND BROAD TROUGH ACROSS THE NORTHEAST US
SLOWLY TRANSLATE EAST THROUGH THE END OF THE WEEK AND INTO THE
WEEKEND.
WEDNESDAY WILL SEE DRYING CONDITIONS BEHIND THE DEPARTING LOW
PRESSURE SYSTEM. TEMPERATURES WILL BE COLD FOR THIS TIME OF
YEAR...ESPECIALLY CONSIDERING 850HPA TEMPS WILL BE AROUND -8 TO -11
C. WITH THE COLD W/NW FLOW ACROSS THE AREA...IT IS POSSIBLE SOME
INTERIOR SECTIONS MAY SEE A FEW FLURRIES CONSIDERING THE GOOD LOW
LEVEL LAPSE RATES.
THE 18/12Z ECMWF AND GFS BOTH SHOW A SHORTWAVE ROTATING AROUND THE
UPPER LOW ON WEDNESDAY NIGHT INTO THURSDAY...AND PASSING OFF THE
MID-ATLANTIC COAST. AS A RESULT...SURFACE CYCLOGENESIS TAKES PLACE
WELL OFFSHORE TO OUR EAST. HOWEVER...THERE LOOKS TO BE ENOUGH OF AN
INFLUENCE TO BRING LOW END CHANCES FOR SOME LIGHT RAIN AND/OR SNOW.
1000-850MB THICKNESSES SUPPORT SNOW...SO GENERALLY SHOW ALL SNOW AT
NIGHT...AND MORE MIXING WITH RAIN DURING THE DAY...CONSIDERING THE
TIME OF YEAR AND SUN ANGLE. NONETHELESS...PRECIP AMOUNTS LOOK TO BE
LIGHT.
WITH RELATIVELY WEAK WAVES CONTINUING TO ROTATE AROUND THE MAIN
UPPER LOW THROUGH THE FIRST HALF OF THE WEEKEND...FRIDAY AND
SATURDAY LOOK TO REMAIN COOL WITH THE POTENTIAL FOR SOME FLURRIES OR
SPRINKLES PRIMARILY DURING THE DAY ACROSS INTERIOR SECTIONS.
A GREAT DEAL OF UNCERTAINTY THEN EXISTS AMONGST THE GLOBAL GUIDANCE
WITH A STRONG WAVE / CLOSED LOW PROPAGATING ACROSS THE CENTRAL AND
EASTERN US THIS WEEKEND...RESULTING IN CYCLOGENESIS OFF THE EASTERN
SEABOARD LATE THIS WEEKEND INTO EARLY NEXT WEEK. WENT WITH SLIGHT
POPS TO ACCOUNT FOR THE POSSIBILITY OF A MORE AMPLIFIED / LESS
PROGRESSIVE WAVE IMPACTING THE REGION. WIDE SPECTRUM OF OUTCOMES AT
THIS TIME.
&&
.AVIATION /22Z MONDAY THROUGH SATURDAY/...
LOW PRESSURE WILL APPROACH FROM THE SOUTHWEST THIS EVENING INTO
TONIGHT.
CIGS ARE LOWERING AND THICKENING AS LOW LEVEL MOISTURE CONTINUES TO
INCREASE. LIGHT SNOW IS EXPECTED TO DEVELOP BETWEEN 20Z AND 22Z.
EASTERLY WINDS WILL CONTINUE TO INCREASE WITH OCCASIONAL GUSTS LATE
THIS AFTERNOON. THE GUSTS WILL BECOME MORE FREQUENT THIS EVENING AS
THE GRADIENT TIGHTENS. IFR CONDITIONS SHOULD DEVELOP AROUND OR AFTER
00Z AS SNOW BECOMES MORE STEADY.
IFR/LIFR CONDITIONS EXPECTED TONIGHT. PRECIPITATIONS IS EXPECTED
TO START AS SNOW EVERYWHERE BEFORE CHANGING OVER TO A MIXED
PRECIP...THEN TO ALL RAIN. NYC METRO TERMINALS SHOULD CHANGE TO
MIXED PRECIP AFTER 02Z AND ALL RAIN BY MIDNIGHT...KHPN CHANGING TO
A MIX AFTER MIDNIGHT AND THEN RAIN BY DAYBREAK...KBDR/KGON CHANGES
TO MIXED PRECIP AND THEN ALL RAIN FROM ABOUT 05Z-08Z...AND KSWF
CHANGING TO FREEZING RAIN AFTER ABOUT 09Z TUE.
THERE COULD BE SOME SLUSHY RUNWAY SNOW ACCUMULATION OF LESS THAN
AN INCH AT THE NYC METRO TERMINALS...AN INCH OR TWO AT
KHPN/KBDR/KGON...AND 4-6 INCHES OF ACCUMULATION AT KSWF. SOME ICE
IS ALSO EXPECTED AT THE HUDSON VALLEY TERMINALS LATE
TONIGHT...UP TO 1/10 AN INCH AT KHPN AND UP TO 1/4 INCH AT KSWF.
RAIN AND/OR DRIZZLE IS EXPECTED TO CONTINUE TUESDAY MORNING.
NY METRO ENHANCED AVIATION WEATHER SUPPORT...

.MARINE...
SMALL CRAFT ADVISORY HAS EXPIRED AND WINDS WILL CONTINUE TO
INCREASE TO GALE FORCE THIS EVENING. GALE WARNING NOW IN EFFECT
AND WILL BE IN EFFECT THROUGH EARLY TUESDAY MORNING.
GALES SHOULD END BY AROUND DAYBREAK TOMORROW...WITH A GOOD CHANCE
OF SCA CONDITIONS BEFORE RAMPING BACK UP TO THE POTENTIAL OF GALE
FORCE WINDS AGAIN TUESDAY NIGHT AS A WEST WIND INCREASES. THE TIME
GAP BETWEEN GALE FORCE WINDS IS TOO LARGE TO CARRY THROUGH 3
PERIODS...SO THE CURRENT GALE WARNING WILL REMAIN THROUGH ONLY
TONIGHT. THE NEXT SHIFT WILL THEN LIKELY NEED TO DETERMINE
APPROPRIATE HEADLINES FOR TUESDAY AND TUESDAY NIGHT.
WINDS WILL SLOWLY DIMINISH WEDNESDAY INTO WEDNESDAY NIGHT...LIKELY
FALLING BELOW SCA CRITERIA LATE IN THE EVENING. HOWEVER...SEAS WILL
REMAIN ELEVATED...UP TO 7 FT ON OCEAN WATERS...THROUGH WEDNESDAY
NIGHT...BEFORE FALLING BELOW 5 FT EARLY THURSDAY. SCA WINDS AND SEAS
WILL POSSIBLY RETURN THURSDAY NIGHT INTO FRIDAY...AS LOW PRESSURE
DEVELOPS TO THE EAST.
&&
.HYDROLOGY...
1 TO 1.50 INCHES OF LIQUID EQUIVALENT IS EXPECTED THROUGH TUESDAY
EVENING. SOME POCKETS OF MINOR URBAN FLOODING MAY BE POSSIBLE. THE
MOST LIKELY TIME THAT THIS WOULD OCCUR WOULD BE LATE THIS EVENING
INTO THE FIRST HALF OF THE OVERNIGHT HOURS.
NO SIGNIFICANT PRECIPITATION IS THEN FORECAST THROUGH THE END OF
THE WEEK.
&&
.TIDES/COASTAL FLOODING...
AROUND 2 TO 3 FT OF SURGE IS NEEDED TO REACH MINOR COASTAL
FLOODING AND AROUND 3 TO 4.5 FT SURGE FOR MODERATE COASTAL FLOODING
FOR HIGH TIDE CYCLE LATE TONIGHT. FORECAST MODELS CONTINUE TO
SHOW AROUND 1 FT OF SURGE FOR SOUTH SHORE AND OCEAN FACING
LOCATIONS INCLUDING THE BATTERY WITH AROUND 1 TO 1.5 FT SURGE ACROSS
WESTERN LONG ISLAND SOUND FOR LATE TONIGHT.
FOR THE TUESDAY AFTERNOON-EARLY EVENING HIGH TIDE CYCLE...AROUND
2.5 TO 3.5 FT OF SURGE IS NEEDED TO REACH MINOR COASTAL FLOODING
AND 3.5 TO 5 FT SURGE TO REACH MODERATE COASTAL FLOODING. FORECAST
SURGE IS ONLY AROUND 0.5 TO 0.75 FT.
THEREFORE...EXPECTING WATER LEVELS TO STAY BELOW MINOR COASTAL
BENCHMARKS EVEN TAKING INTO ACCOUNT NEGATIVE BIAS WITH SURGE MODELS.
ASTRONOMICALLY WE ARE APPROACHING HALF MOON PHASE SO WATER LEVELS
ARE LOWER AND WE WOULD NEED MORE SURGE TO REACH MINOR COASTAL
FLOODING AS A RESULT. THIS WILL CONTINUE TO NEED MONITORING TO
VERIFY WATER LEVELS TODAY AND THIS EVENING TO SEE IF THERE IS ANY
POSITIVE TREND TO SUBSEQUENT SURGE FORECASTS.
