NATIONAL WEATHER SERVICE NEW YORK NY

SYNOPSIS
HIGH PRESSURE MOVING OFF THE MID ATLANTIC COAST LATE TODAY WILL
SLIDE EAST TONIGHT INTO TUESDAY. A WARM FRONT WILL THEN LIFT
NORTH THROUGH THE WATERS TUESDAY NIGHT, FOLLOWED BY A COLD FRONT
WEDNESDAY NIGHT. THE AREA WILL THEN REMAIN IN BETWEEN STRONG
LOW PRESSURE TO THE NORTH AND STRONG HIGH PRESSURE TO THE SOUTH
AND WEST FROM THANKSGIVING DAY THROUGH EARLY SATURDAY. THE HIGH
WILL BUILD IN FOR MUCH OF THE WEEKEND. A COLD FRONT MAY IMPACT
THE AREA TOWARD THE END OF THE WEEKEND INTO EARLY NEXT WEEK.
NEAR TERM /THROUGH TONIGHT/
A 1025 SFC HIGH OVER THE MID ATLANTIC WILL SLIDE OFF THE COAST
TONIGHT, WHILE ITS TRAILING UPPER LEVEL RIDGE APPROACHES. BKN
HIGH/MID LEVEL CLOUDS ALREADY SPILLING OVER THE UPPER RIDGE AXIS
OVER WRN PA AND THE OH VALLEY WILL MOVE IN ESPECIALLY LATE
THIS EVENING AND OVERNIGHT. ALONG WITH DIMINISHING WINDS AND
MOSTLY CLEAR SKIES BEFORE THEY ARRIVE, TEMPS IN MANY AREAS MAY
BOTTOM OUT AROUND OR SHORTLY AFTER MIDNIGHT, THEN LEVEL OFF
OVERNIGHT. LOWS ARE A COLDER GFS/NAM MOS BLEND, RANGING FROM
25-30 WELL INLAND AND ACROSS THE LONG ISLAND PINE BARRENS, TO
NEAR 40 IN NYC.
SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/
THE UPPER RIDGE SHOULD PASS EAST EARLY TUE AM, FOLLOWED BY A
MID LEVEL SHORTWAVE TROUGH APPROACHING FROM THE OH VALLEY. LIGHT
OVERRUNNING RAINFALL AHEAD OF THE TROUGH AND A LEADING WARM
FRONT SHOULD ARRIVE BY LATE DAY FROM THE NYC METRO AREA WEST,
THEN OVERSPREAD THE REST OF THE AREA TUE EVENING. A PERIOD OF
MODERATE RAINFALL EXPECTED AS A 50-KT S-SW LLJ TRANSPORTS
MOISTURE AND PROVIDES LIFT/CONVERGENCE AND SOME MEAGER
INSTABILITY MOSTLY BELOW THE FREEZING LEVEL. BECAUSE THE
INSTABILITY WILL BE LIMITED TO LOWER LEVELS, HAVE REMOVED
MENTION OF THUNDER THOUGH THERE COULD STILL BE A CONVECTIVE
ASPECT TO THE PRECIP AT ITS PEAK VIA SOME MEAGER H8-5
INSTABILITY.
SHOWERY PRECIP SHOULD CONTINUE AT TIMES IN THE WARM SECTOR WED
INTO WED EVENING, THEN AS VERTICALLY STACKED LOW PRESSURE CROSSES
THE UPPER GREAT LAKES, A TRAILING COLD FRONT WILL MOVE ACROSS
LATE WED NIGHT, WITH PRECIP ENDING AND W WINDS PICKING UP.
TEMPS DAYTIME TUE WILL RISE INTO THE LOWER/MID 50S, THEN ONLY
FALL BACK SLIGHTLY INTO THE 40S TUE NIGHT. HIGHS IN THE WARM
SECTOR ON WED SHOULD REACH THE LOWER 60S IN MANY SPOTS BEFORE
SHARPLY FALLING OFF LATE WED NIGHT TO THE 30S AND LOWER 40S
AFTER COLD FROPA.
LONG TERM /THURSDAY THROUGH SUNDAY/
KEY POINTS:
* WINDY CONDITIONS LOOKING MORE LIKELY THANKSGIVING DAY THROUGH
FRIDAY. POSSIBILITY FOR WIND GUSTS 30-35 MPH THANKSGIVING DAY,
AND 35-40 MPH WITH ISOLATED GUSTS UP TO 45 MPH ON FRIDAY.

THROUGH SATURDAY WITH HIGHS IN THE LOWER/MID 40S AND WIND
CHILLS IN THE 30S.
* MAINLY DRY THROUGH THIS PERIOD, WITH CHANCES OF RAIN TOWARD THE
END OF THE WEEKEND INTO EARLY NEXT WEEK.
A LARGE ANOMALOUS UPPER LEVEL LOW AND TROUGH CONTINUE TO
APPROACH THE AREA ON THURSDAY. AT THE SURFACE, STRONG LOW
PRESSURE WILL BE PASSING TO OUR NORTH WHILE STRONG HIGH PRESSURE
SETS UP TO OUR SOUTHWEST. THIS PLACES THE AREA IN A TIGHT
PRESSURE GRADIENT AND WILL BRING WINDY CONDITIONS THURSDAY
THROUGH FRIDAY. PEAK WINDS ARE EXPECTED ON FRIDAY WHEN DEEP
MIXING WILL ALLOW FOR WIDESPREAD GUSTS UP TO 35-40 MPH. THE NBM
90TH PERCENTILE WAS USED FOR GUSTS AS THE NBM HAS BEEN
UNDER-DOING WINDS IN THESE DEEP MIXING W-NW FLOW REGIMES. THE
FORECAST MAY CONTINUE TO TREND UP. AT THIS TIME ADVISORY LEVEL
GUSTS ARE EXPECTED TO BE ISOLATED.
HIGH PRESSURE EVENTUALLY BUILDS IN AND SHOULD BE IN CONTROL MUCH
OF THE WEEKEND. THERE IS SOME DISAGREEMENT IN TIMING OF WHEN
THE HIGH WILL BE CENTERED OVER US. IF THE LATEST GFS ENDS UP
BEING RIGHT, THE SATURDAY NIGHT LOW TEMPERATURE FORECAST WILL
END UP TRENDING DOWN AND WE MAY SEE SOME UPPER TEENS ACROSS THE
INTERIOR.
A COLD FRONT APPROACHES LATE IN THE PERIOD AND COULD BRING SOME
RAIN TO END THE WEEKEND AND START NEXT WEEK. STUCK WITH NBM
POP FOR NOW, BUT TIMING WILL BE REFINED AS WE GET CLOSER.
