Area Forecast Discussion
National Weather Service New York NY
723 PM EDT Mon Sep 8 2025

.SYNOPSIS...
High pressure stays in control through at least Tuesday. An 
offshore wave of low pressure may come close enough to impact 
the area on Wednesday. High pressure settles in for the second 
half of the week and into the weekend. A cold front likely 
slides through Sunday night, followed by Canadian high pressure 
early next week.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
High pressure continues to build in tonight with primarily 
clear skies expected. This will allow for efficient radiational 
cooling for the first half of the night. Then developing 
offshore low pressure will lead to increasing E/NE winds from a 
pressure gradient for the second half of the night. This will 
hamper radiational cooling in areas east and south. Overall 
expecting lows to be in the mid/low 50s across the southern 
half/coastal parts of the area. Then lows may dip int the 
mid/upper 40s for northern interior sections.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH WEDNESDAY NIGHT/...
High pressure remains in control on Tuesday, but weakens its 
influence Tuesday night as it pushes more north, giving way to a
nearby coastal wave of low pressure. Dry conditions are 
expected Tuesday. Tuesday morning will be mostly sunny with 
cloud cover gradually increasing south to north through the 
afternoon and into Tuesday night.

Then on Wednesday, showers are possible for southern and 
eastern portions of the CWA, with the highest chances on eastern
Long Island. This is in response to the nearby wave of low 
pressure. THis rainfall is expected to taper west to east 
Wednesday night as high pressure builds back in from the west. 

Cool weather persists through this period with highs in the 
70s. Lows will be a bit warmer than whats expected tonight given
more cloud cover and wind, mainly 50s.

&&

.LONG TERM /THURSDAY THROUGH MONDAY/...
A large dome of high pressure will be in control for the second
half of the week and into the weekend. The high will then 
weaken on Sunday with a cold front swinging through for the tail
end of the weekend, likely during Sunday night. At this time 
little in terms of sensible weather is expected with the this 
front, although there seems to be a good amount of spread at 500
mb with the global deterministic models. Stayed largely with 
the NBM throughout the period, even for late Sunday into Sunday 
night. Although slight chance or low end chance PoPs may be 
warranted for Sunday night have held off including it for now. 
So no changes in terms of sensible weather throughout the period
with this package. Overall near seasonable temperatures and 
predominantly dry.

&&

.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
High pressure prevails through the TAF period.

VFR.

Light SE winds early this evening, with weakening seas breezes,
become light NE to light and variable by late evening. Winds 
become more easterly Tuesday morning and increase to near 15 kt
along the coast. Gusts also possible along the coast Tuesday
morning into the afternoon, 17 to 22 kt. Uncertain on frequency
of gusts, and may be more occasional.

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

E to NE gusts late Tuesday morning into the late afternoon may
be more occasional, especially at KEWR and KTEB. 

.OUTLOOK FOR 00Z WEDNESDAY THROUGH SATURDAY...

Tuesday night: VFR. Chance of MVFR late at night at KISP and
KGON with showers.

Wednesday: Potential for MVFR in -SHRA, mainly east of NYC 
terminals. Otherwise, mainly VFR.
 
Thursday-Saturday: VFR.

.MARINE...
A Small Craft Advisory is issued for the ocean waters Tuesday 
through Wednesday due to building 5 to 6 ft seas. Through that time, 
wind gusts likely stay under 25 kt, but isolated 25 kt gusts can not 
be ruled out.

Sub-advisory conditions are expected for Thursday through Saturday 
with mainly 3 to 4 ft seas on the ocean.

&&

.HYDROLOGY...
There are no hydrologic concerns through the entire forecast
period.

&&

.TIDES/COASTAL FLOODING...
SE swells at around 8 seconds along with an increasing E wind wave 
will result in a high rip current risk by Tuesday afternoon. The 
high risk should continue into Wednesday with similar conditions in 
place.

Minor coastal flood benchmarks will begin to be approached during 
times of high tide beginning on Tuesday. Coastal flood statements 
have been issued for the SW CT and So Westchester coastal zones for 
the early afternoon high tide cycle, and the Nassau south shore bays 
for the Tuesday evening cycle. It appears that water levels will 
fall short of minor thresholds for So. Nassau Tuesday morning, but 
could reach minor benchmarks for the evening cycle. There will be a 
continued risk of minor coastal flood benchmarks being reached for 
the late morning / early afternoon high tides on both Wednesday and 
Thursday, and minor coastal flood benchmarks may be reached for 
portions of Staten Island and So. Queens in subsequent cycles.
