AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
1037 PM EDT THU OCT 9 2025
SYNOPSIS
HIGH PRESSURE CONTINUES TO BUILD OVERNIGHT AND WILL THEN REMAIN
OVER THE AREA INTO THE START OF THE WEEKEND. LOW PRESSURE WILL
DEEPEN AND TRACK NORTH TOWARDS THE REGION ON SUNDAY. THE LOW
WILL THEN MEANDER NEAR THE REGION ON MONDAY, BEFORE HEADING OUT
TO SEA BY THE MIDDLE OF THE WEEK.
NEAR TERM /UNTIL 6 AM FRIDAY MORNING/
STRONG HIGH PRESSURE CONTINUES TO BUILD INTO THE AREA FROM THE
NORTHWEST OVERNIGHT, EVENTUALLY MOVING DIRECTLY OVERHEAD INTO
FRIDAY MORNING. CLEAR SKIES AND LIGHT WINDS WILL ALLOW FOR SOME
RADIATIONAL COOLING, ESPECIALLY FOR INLAND AREAS AWAY FROM THE
IMMEDIATE COASTLINE, AND THE PINE BARRENS OF LONG ISLAND. CAA
FROM THE NORTHERLY FLOW EARLIER THURSDAY, A DRIER AIRMASS, AND
A DECOUPLED BOUNDARY LAYER WILL ALLOW FOR SURFACE TEMPERATURES
TO DROP SIGNIFICANTLY BRINGING THE POTENTIAL FOR THE FIRST
FREEZE OF THE SEASON.
INLAND AREAS TO THE NORTH ARE EXPECTED TO FALL INTO THE LOWER 30S,
POSSIBLY EVEN SOME UPPER 20S. FREEZE WARNINGS CONTINUE FOR THESE
INLAND AREAS. CLOSER TO THE COAST, MIDDLE TO UPPER 30S ARE POSSIBLE,
WITH THE IMMEDIATE COASTLINE HAVING LOW TEMPERATURES INTO THE LOW TO
MIDDLE 40S, COURTESY OF OCEAN TEMPERATURES REMAINING IN THE 60S. ANY
COOLER SPOTS NOT ALONG THE IMMEDIATE COASTLINE MAY DEVELOP SOME
FROST TONIGHT, WITH FROST ADVISORY HEADLINES ISSUED FOR PORTIONS OF
SOUTHERN COASTAL CONNECTICUT AND INTERIOR PORTIONS OF NE NJ. THERE
IS ALSO A CHANCE FOR SOME FROST ACROSS THE LI PINE BARRENS WITH
TEMPERATURES AROUND 32 DEGREES, BUT NOT ENOUGH OF THE ZONE FOR ANY
HEADLINE.
SHORT TERM /6 AM FRIDAY MORNING THROUGH SATURDAY NIGHT/
HIGH PRESSURE THEN REMAINS IN CONTROL OF THE AREA FRIDAY AND
SATURDAY. GENERALLY CLEAR CONDITIONS FRIDAY WITH A GRADUALLY
SHIFTING WIND OUT OF THE SOUTHEAST WILL ALLOW FOR TEMPERATURES
TO CLIMB INTO THE LOWER 60S, STILL ABOUT 5 DEGREES BELOW
AVERAGE. THE SE COMPONENT TO THE WIND AS THE HIGH PRESSURE
CENTER SHIFTS EAST OF THE AREA WILL ALLOW LOWER LEVEL MOISTURE
TO ADVECT INTO THE AREA AND DEW POINTS TO INCREASE INTO THE LOW
40S. GIVEN THE INCREASE IN LOW LEVEL MOISTURE AND POTENTIALLY
SOME CLOUD COVER MOVING IN FRIDAY NIGHT, LOW TEMPERATURES ON
FRIDAY NIGHT WILL BE WARMER THAN THURSDAY NIGHT. LOWS FRIDAY
NIGHT WILL BE IN THE 40S AND 50S WITH WARMER SPOTS NEAR THE NYC
METRO AND ALONG THE IMMEDIATE COAST.
HIGH PRESSURE REMAINS JUST NORTH OF THE AREA ON SATURDAY WITH A
DEVELOPING COASTAL LOW APPROACHING THE AREA FROM THE SOUTH.
THIS WILL ALLOW FOR INCREASED CLOUD COVER AND A GRADUALLY
INCREASING SE/E FLOW THROUGH THE DAY. HIGHS SATURDAY WILL BE IN
THE MIDDLE TO UPPER 60S TO NEAR 70. SOME SHOWERS MAY APPROACH
THE AREA FROM THE SOUTH TOWARD LATE AFTERNOON.
LONG TERM /SUNDAY THROUGH THURSDAY/
THE MAIN FOCUS CONTINUES TO BE ON THE STORM FOR SUN INTO EARLY
NEXT WEEK, WITH SIGNIFICANT CSTL IMPACTS POSSIBLE.
THE MODELS CONTINUE TO SUPPORT LOW PRES DEEPENING AND TRACKING NWD
TOWARDS THE REGION ON SUN, WHILE HIGH PRES REMAINS OVER ERN CANADA.
ALTHOUGH THERE ARE SOME TIMING, TRACK, AND STRENGTH CHALLENGES, THIS
PATTERN LENDS CONFIDENCE TO THE WIND FIELD DUE TO THE RELATIVE
POSITIONS OF THE HIGH AND LOW. AS A RESULT, ISSUED HIGH WIND AND
CSTL FLOOD WATCHES FOR THE AREA.
THE STRONGEST WINDS ARE STILL EXPECTED TO BE ACROSS SRN/ERN PORTIONS
OF THE CWA AND THIS IS WHERE THE WATCH HAS BEEN ISSUED. OTHER AREAS
WILL STILL BE WINDY, BUT LIKELY ADVY LVLS OR LOWER ATTM. IF THE
STORM TRACK TRENDS WWD, THIS WOULD EXPAND THE WIND FIELD WWD AS
WELL, BUT MAY LIMIT PEAK GUSTS IF THE LOW ENDS UP WEAKER. WILL
CONTINUE TO FCST A MAX GUST TO AROUND 60 MPH DURING THE PEAK OF THE
STORM BASED ON 50KT BL WINDS IN THE GFS. THIS SIGNAL HAS BEEN
PERSISTENT.
DID MAKE SOME CHANGES TO THE NBM, BLENDING IN THE HIGHER 06Z CONSALL
FOR WINDS SAT NGT THRU MON OVER LAND, AND MANUALLY INCREASING GUSTS
THERE ABV THE NBM AS WELL.
THE RAIN DEVELOPS FROM S TO N ON SUN. THE NAM HOWEVER IS COMPLETELY
DRY UNTIL EVE. STUCK WITH THE NBM WHICH IS CLOSER TO THE FASTER GFS
AS IT IS A BIT TOO FAR OUT TO HAVE CONFIDENCE IN THE SLOWER NAM.
RIGHT NOW THE WINDOW FOR THE HEAVIEST RAIN LOOKS TO BE SUN AFTN AND
EVE, ALTHOUGH THIS COULD CHANGE DUE TO THE EVENTUAL TRACK, TIMING,
AND INTENSITY OF THE SYS.
IT REMAINS WINDY ON MON, BUT THE GRADIENT RELAXES SO PEAK GUSTS ARE
NOT EXPECTED TO BE AS HIGH. STILL GUSTS AROUND 40 MPH VERY POSSIBLE.
IF THE LOW GETS CLOSE ENOUGH, LIGHTER WINDS COULD BE POSSIBLE WITH
THE STRONGEST FLOW GENERALLY ON THE PERIPHERY OF AN OCCLUDED LOW.
THE GFS IS STARTING TO SUGGEST THIS POSSIBILITY, BUT THE ECMWF HAS
COME IN SOLIDLY S, KEEPING THE AREA IN A STRONG E/NE FLOW.
THE STORM WEAKENS AND PULLS AWAY ON TUE, SO LESSENING RAIN CHANCES
AND DECREASING WINDS, ALTHOUGH PROBABLY STILL BREEZY AT THE COASTS.
NO CHANGES TO THE NBM WED AND THU.
AVIATION /03Z FRIDAY THROUGH TUESDAY/
VFR AS HIGH PRESSURE SETTLES ACROSS THE AREA EARLY FRIDAY, AND
THEN MOVES SLOWLY EAST INTO FRIDAY AFTERNOON.
NNE WIND CONTINUES OVERNIGHT 5 TO LESS THAN 10 KT, WITH LIGHT
AND VARIABLE CONDITIONS AT A FEW LOCATIONS. WINDS WILL THEN
BECOME E/SE TOWARDS LATE FRIDAY MORNING, AND SE FRIDAY
AFTERNOON, WITH WEAK SOUTHERLY SEA BREEZES POSSIBLE.

MARINE
WINDS AND SEAS CONTINUE TO SUBSIDE OVERNIGHT AS HIGH PRESSURE
MOVES OVERHEAD. SUB-SCA CONDITIONS ARE EXPECTED THROUGH SATURDAY
AFTERNOON.
WINDS INCREASE SAT NGT, PARTICULARLY ON THE OCEAN, AHEAD OF
DEVELOPING LOW PRES. A GALE WATCH HAS BEEN ISSUED FOR THE OCEAN.
WINDS INCREASE TO POSSIBLY STORM FORCE FOR SUN AND SUN NGT. A STORM
WATCH HAS BEEN ISSUED FOR ALL WATERS EXCEPT THE HARBOR, WHERE A GALE
WATCH WAS ISSUED. ALL AREAS SHOULD BE CLOSE TO GALE ON MON. SEAS
LIKELY TO PEAK AROUND 20FT ON THE OCEAN WITH THE SYS. WINDS AND SEAS
SUBSIDE FURTHER MON NGT AND TUE AS THE LOW WEAKENS AND BEGINS TO
TRACK AWAY FROM THE REGION.
HYDROLOGY
WIDESPREAD RAIN IS EXPECTED SUNDAY INTO MONDAY. AVERAGE AMOUNTS
OF 1 TO 2 INCHES ARE POSSIBLE. HOWEVER, NO SIGNIFICANT
HYDROLOGIC IMPACTS ARE EXPECTED WITH THIS BEING A LONG DURATION
RAINFALL AND RECENT DRY CONDITIONS.
TIDES/COASTAL FLOODING
TOTAL WATER LEVELS ARE EXPECTED TO APPROACH AND POSSIBLY JUST
MEET MINOR COASTAL FLOOD BENCHMARKS FRIDAY MORNING'S HIGH TIDE
CYCLE FOR THE NASSAU COUNTY SOUTH SHORE BAYS AND S FAIRFIELD.
IMPACTS SHOULD BE MINIMAL.
THE POTENTIAL REMAINS FOR WIDESPREAD MODERATE TO LOCALLY MAJOR
COASTAL FLOODING AND BEACH EROSION SUNDAY AND MONDAY, VIA THE
COMBO OF HIGH ASTRONOMICAL TIDES AND SURGE GENERATED BY STRONG
NE FLOW. BREAKING WAVES AROUND 10 FT POSSIBLE BASED ON 20+ FT
SEAS OFFSHORE. ALTHOUGH EXACT IMPACTS WILL BE DEPENDENT ON THE
EVENTUAL TRACK AND INTENSITY OF A DEEP LOW TRACKING TOWARD THE
REGION, CONFIDENCE IN THE EVENT WAS HIGH ENOUGH TO WARRANT THE
ISSUANCE OF A WATCH FOR THE ENTIRE COAST.
