Area Forecast Discussion
National Weather Service New York NY
305 AM EDT Mon Oct 6 2025

.SYNOPSIS...
High pressure over the area today will move to the east on
Tuesday. A cold front will then approach Tuesday night and
pass through early Wednesday, followed by high pressure through
late week/ Low pressure may pass south and east of Long Island
some time this weekend.

&&

.NEAR TERM /THROUGH TONIGHT/...
Patchy fog and low stratus was most evident on 11.2-3.9um
channel difference satellite imagery over SE CT, with perhaps
some valley fog across the interior and also across parts of
eastern Long Island. This should burn off fairly quickly after
sunrise, and expect temps to quickly respond under mostly sunny
skies, with high temps reaching the lower/mid 80s in most
places, and the 70s along coastal SE CT and the south shore of
Long Island, per blend of NBM 90th percentile and GFS/ECMWF MOS
guidance which have done better than straight NBM with recent
warmth. This also lines up fairly well with model fcst 925 mb
temps which look about 1 degree C cooler than those of
yesterday.

Low temps tonight should be fairly similar to those of Sunday
night, with lower 60s in NYC and surrounding suburbs, and in the
50s elsewhere. Some patchy fog is possible across the interior

&&

.SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/...
As the high weakens on Tue, S flow will increase ahead of an
approaching cold front, with increasing clouds as well
especially in the afternoon. High temps will reach the upper
70s/lower 80s one last time before a cooler regime sets in.

Showers with the front will move in Tue night, with the highest
PoP late Tue night into Wed morning just ahead of the front, and
can`t rule out some rumbles of thunder with fropa.
Shower chances continue mainly E of NYC going into Wed
afternoon, and except for perhaps some lingering showers out
east most precip should be over by Wed night. It will be cooler
on Wed, with daytime highs only in the upper 60s/lower 70s, then
lows mostly in the 40s as a somewhat brisk northerly flow
gusting up to 20-25 mph at times transports cooler air down into
the area.

&&

.LONG TERM /THURSDAY THROUGH SUNDAY/...
NBM was followed with no significant changes. Key Points:

* High pressure keeps the area dry through Saturday afternoon.
  High temperatures will be in the 60s from Thursday through
  Saturday.

* Coastal low pressure may bring rainfall Saturday night and
  Sunday.

&&

.AVIATION /06Z MONDAY THROUGH FRIDAY/...
High pressure remains in control through the TAF period.

Mainly VFR conditions are expected. The only exception will be
tempo to prevailing MVFR-IFR cigs and/or vsbys until 12-14z
mainly at KGON and KHPN, but possibly at KISP and KBDR as well.

A light SW flow will become S late this morning and early
afternoon with speeds at around 10 kt or less. Lighter SW
winds for tonight.

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

No unscheduled amendments expected.

.OUTLOOK FOR 06Z TUESDAY THROUGH FRIDAY...

Late tonight-Tuesday: VFR. MVFR-LIFR conditions possible for
outlying terminals possible late at night into early Tuesday
morning. SW winds G15-20kt Tuesday afternoon into evening.

Tuesday night-Wednesday: MVFR, possibly IFR at times, with
showers, ending Wednesday afternoon and evening. Slight chance
of a thunderstorm. VFR returns by Wednesday night. NW-N wind
gusts 15-20kt Wednesday afternoon into night.

Thursday-Friday: VFR.

.MARINE...
As S flow increases to 15-20 kt ahead of an approaching cold
front on Tue, ocean seas E of Fire Island Inlet may build to 5
ft Tue night into Wed. Post-frontal NW flow may gust to 20 kt
daytime Wed, then as winds veer N gusts should increase to 25-30
kt on all waters Wed night, with ocean seas 4-6 ft.

Minimal SCA cond are still likely on the ocean Thu morning with
gusts up to 25 kt and seas up to 5 ft, then winds and seas are
expected to be below criteria on all waters Thursday afternoon
through Saturday.

&&

.HYDROLOGY...
Rainfall with a frontal passage tue night into Wed could be as
much as 3/4 to 1 inch across Long Island and SE CT, and 1/2 to
3/4 inch north/west of there including NYC. No hydrologic issues
expected as this rainfall will be beneficial.
