Area Forecast Discussion
National Weather Service New York NY
137 PM EST Fri Nov 14 2025
.SYNOPSIS...
High pressure builds over the region this evening and remains
tonight. The high pushes offshore Saturday. A warm front slowly
approaches Saturday and pushes through Saturday night, followed
quickly by a cold front Sunday morning. The departing low moves
into eastern Canada Sunday into Sunday night. High pressure
builds in from the west Monday into Tuesday and settles nearby
into Thursday. A frontal system may then impact the region
Thursday night into Friday.
&&
.NEAR TERM /THROUGH TONIGHT/...
An upper ridge builds toward the area tonight with a surface
high also building over the area between two low pressure
systems. Skies become mostly clear to clear with diminishing
winds, which may become near calm by late tonight. Temperatures
fall below freezing inland, and into the mid and upper 30s along
the coast and across metropolitan NYC. With winds becoming near
calm lows may be a degree or two lower. Widespread frost is
likely inland, with areas along the coast. The growing season
remains across southern Nassau county, however, did not issue a
frost advisory as conditions will be marginal, with areal
extent, temperatures, and sort duration of areas of frost.
&&
.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
An upper ridge builds over the area Saturday and weakens late
in the day as the surface high moves offshore. A rather strong
warm front will approach from the southwest Saturday night, and
strong low level warm advection sets up early in the evening.
Low temperatures will most likely occur during the evening with
a non diurnal temperature rising through the overnight as the
warm front approaches and then quickly lifts north toward Sunday
morning, 09Z to 12Z. With strong isentropic lift along the warm
front showers will become likely late day and more into
Saturday evening and night. The region will only be warm
sectored briefly as a cold front quickly follows as the
associated low tracks north of the region. Again, temperatures
will be semi non diurnal Sunday as highs will occur early in the
day and hold steady into the early afternoon before falling as
the colder air moves into the region. Did not mention any
thunder with the cold front as any CAPE will be limited and
brief, and shallowly elevated. Carried minimum probabilities or
precipitation into Sunday morning across the eastern portion of
the region, however, with the quick movement of the low and cold
front precipitation may be over before Sunday morning. West /
Northwest winds in the wake of the cold front develop Sunday and
continue into Sunday night, and will likely remain below Wind
Advisory levels. There may be a few gusts approaching 40kt late
morning into the early afternoon as the strongest cold
advection moves through with the strongest pressure rises.
&&
.LONG TERM /MONDAY THROUGH FRIDAY/...
Key points:
* Breezy conditions are expected to begin the period on Monday,
followed by gradually diminishing winds Monday night into Tuesday.
* High temperatures below normal through Wednesday, moderating to
near normal for Thursday and Friday.
* Likely dry through at least Thursday afternoon with rain chances
for Thursday night and Friday. Too early to have any confidence
regarding impacts.
Relatively high confidence forecast through Thursday. Uncertainty
increases Thursday night into Friday surrounding the track and
timing of low pressure that would appear to pass to our north at
some point late this week. Did not stray from NBM during this
period. NBM is reasonably close to AI GEFS and AI EPS regarding
track and timing as implied by NBM wind fields. With that said, it
appears that the global deterministic models may have just started
converging on a solution with a slower timing of the system and its
potential impacts.
&&
.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
Low pressure exits north across the Canadian Maritimes today,
while high pressure gradually builds in from the southwest.
VFR. A few sprinkles or flurries could make their way into the
area late this afternoon/early evening, particularly for
terminals in the lower Hudson Valley and southern Connecticut,
but restrictions are not expected.
WNW-NW flow has thus far underperformed slightly than forecast.
Now expecting winds around 10 kt with a few near 15 kt while
gusts have been reigned in, mainly peaking around 20 kt. Winds
will fall off quickly this evening, veering more NW/NNW at
night. Flow backs SW late Saturday morning into early afternoon
as speeds remain at or under 10 kt until the evening, before
they begin to climb again.
...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...
Gusts may be more occasional through midday.
Timing of frequent gusts developing could be off 1-2 hours.
.OUTLOOK FOR 18Z SATURDAY THROUGH WEDNESDAY...
Saturday Night: MVFR or lower w/ rain.
Sunday: MVFR or lower in rain to start, improving to VFR by the
afternoon. W winds 10-15 G20-25kt late morning/afternoon.
Monday: VFR. W-WNW winds 15-20G25-30kt.
Tuesday: VFR.
Wednesday: VFR.

.MARINE...
A Small Craft Advisory remains on the ocean waters through this
afternoon as westerly wind gusts continue behind departing low
pressure, and as high pressure builds in from the southwest.
Also, seas are marginally near 5 feet east of Moriches Inlet.
With the high building in conditions will fall below advisory by
late in the day. Then conditions remain below advisory levels
until Saturday night as the high moves offshore and a frontal
system approaches from the Great Lakes region. Wind gusts will
reach SCA levels on all the waters during Saturday night, and
once the current advisory ends a SCA will likely be issued for
all the waters for Saturday night. Wind gusts continue to
increase into Sunday morning as winds become westerly behind a
cold front that quickly sweeps across the forecast waters. Gusts
will be at gale force across all the waters Sunday through
Sunday night and a Gale Watch has been issued.
Gales will still be possible on all waters through Monday before
eventually diminishing below advisory thresholds Monday night into
Tuesday morning. Sub-advisory conditions then prevail through the
rest of the forecast period with a high pressure ridge over the
area.
