Area Forecast Discussion
National Weather Service New York NY
940 AM EST Wed Nov 26 2025

.SYNOPSIS...
A cold front approaches today and moves across the area tonight.
The region will then remain between strong low pressure to the
north and high pressure well southwest for the remainder of the
week. High pressure settles over the area on Saturday before
moving offshore on Sunday. A cold front moves across the area
Sunday night into Monday.

&&

.NEAR TERM /THROUGH TONIGHT/...
A warm front will remain just north or over the area into the
afternoon. A cold front will follow tonight.

Low clouds and some patchy fog will be the main story for the
rest of the daytime. A few showers are also possible, especially
late day into the evening as the cold front moves across the
area.

Otherwise, it will remain mild with temperatures in the mid to
upper 50s. Some locations could reach the lower 60s near the
coast this afternoon.

Much colder and drier air returns late tonight behind the cold
front. Strong cold advection will increase boundary layer mixing
with westerly gusts 20-30 mph possible early in the morning.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
Key points

* Winds of near 20 mph with gusts near 35 to 40 mph forecast for
  Thanksgiving. High temperatures Thanksgiving mainly low to mid 40s
  but wind chills stay in the 30s.

* Winds of near 25 mph with gusts near 40 to 45 mph forecast for
  Friday. There is still some model indication of near 50 mph
  wind gusts being possible. High temperatures Friday mainly in
  the upper 30s to lower 40s with wind chills staying mostly in
  the 20s to lower 30s.

The key points with the short term will be gusty winds and with the
higher winds, cold temperatures as well as wind chills. No
measurable precipitation is expected during the timeframe of
Thanksgiving through Friday night. There could be a few light
rain/snow showers with strong mid level vorticity maximum
pushing across on Friday. A much colder airmass will be across
the region during the short term.

Mid and upper level trough move into the region Thanksgiving into
Friday with upper level jet moving south of the region. The mid and
upper level flow become less amplified Friday night with that
flattening of the flow, returning to nearly zonal. At the surface,
parent low pressure moves eastward within Quebec. High pressure
remains well south and west of the region. Model guidance indicates
slight rising pressure magnitude of the parent low and lowering of
the high pressure magnitude. Still a steep pressure gradient is
expected but the peak wind gusts are still a forecast parameter with
associated low confidence. Maintained continuity with previous
forecast, showing how Friday will be tighter pressure gradient and
higher winds and gusts compared to Thursday.

Deep vertical mixing is still expected Friday to around 7 to
8kft. While NBM is indicating very low probabilities of wind
gusts exceeding 45 mph, the NBM has recently under-predicted
wind gusts and still exhibits this bias for parts of the Central
US with their current system, which will actually be the same
system that passes to the north of the local area towards the
end of this week. GFS BUFKIT and NAM BUFKIT both show top of
mixed layer for a few locations with winds near 40-45 kt and the
GFS BUFKIT has been showing this a few times with multiple
model runs for Friday. On a westerly flow, efficient vertical
mixing and winds near the top of the mixed layer can more easily
be brought down to the surface.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
NBM followed with some slight adjustments to temperature Sunday
night. Previous discussion follows.

Key Point:

* Mainly dry through at least the first half of this period,
  with confidence increasing in rain late in the weekend into
  early next week.

The high builds in on Saturday and passes overhead Saturday evening.
A cold front then approaches the area and will bring the next
chances of rain late Sunday into the start of next week.

&&

.AVIATION /15Z WEDNESDAY THROUGH SUNDAY/...The remainder of the showers associated with the current frontal
system through tonight is forecast to result near a half inch or
less of rain. No hydrologic problems are expected with this and
thereafter for the rest of the forecast period.A warm front,
currently across western New Jersey and into the Lower Hudson
Valley moves slowly to the north through this afternoon, and is
then followed by a cold front passing through this evening into
late tonight.

MVFR/IFR cigs and vsbys persist through the day, with a chance
of LIFR at time into early afternoon, will gradually becoming
VFR this evening, though the timing of the category changes
remain uncertain due to the timing of the cold front. Much of
the day should be dry with a few scattered showers possible,
especially for coastal areas. A heavier downpour is possible
with the cold frontal passage, with the best chance between
23Z-03Z.

A S/SW flow around 10kt through the day is expected. Some
variability in wind direction is possible this morning,
especially away from the coast. Winds shift to the W and become
gusty once again late tonight behind the frontal passage. Gusts
tonight around 25-30kt possible.

 ...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...

Amendments likely for changing flight categories through the day.

Low confidence for changing flight category timing.

.OUTLOOK FOR 12Z THURSDAY THROUGH SUNDAY...

Thursday: VFR. W flow 15-20 kt with gusts 25-35 kt.

Friday: VFR. WNW flow 15-25 kt with gusts 30-40 kt.

Saturday: VFR. NW flow with gusts 15-20 kt.

Sunday: Chance of MVFR or lower and rain.

.MARINE...
SCA remains in effect for the ocean waters through Thursday
with gale watch remaining in effect for the ocean waters
thereafter for Thursday night through Friday. SCA conditions are
then likely on the non-ocean waters this evening through
Thursday night. Gales are then possible Thursday night into
Friday on the ocean and on Friday on the non-ocean waters. The
Gale watches remain in effect.

Note some gale force winds are possible immediately behind the
cold front tonight and during the day Thursday but just
occasional in frequency.

Gale force winds forecast on all waters Friday will gradually trend
down to SCA levels Friday night.

SCA conditions then likely linger through the first half of Saturday
before dropping below SCA criteria. The next shot at SCA looks to be
early next week with the passage of a cold front.
