667 FXUS61 KOKX 071140 AFDOKX Area Forecast Discussion National Weather Service New York NY 740 AM EDT Mon Sep 7 2026 .WHAT HAS CHANGED... No significant changes made since the previous update. && .KEY MESSAGES... 1) Conditions potentially meeting advisory or warning criteria on land are not expected through the forecast period. && .DISCUSSION... .KEY MESSAGE 1... High pressure will provide the area with dry conditions through most of the forecast period. The only chances of rain appear to be during late Wednesday night through Thursday evening as a cold front approaches and passes through. Highest chances would be during Thursday afternoon, but probabilities are still only around 40% during that time. Regarding thunderstorms, enough CAPE is progged for a chance of thunder Thursday afternoon and evening but not very supportive of severe wx. Shear would slowly diminish through the day, so that would work against severe wx chances. Will need to watch the trends in progged CAPE and shear as the day approaches. && .AVIATION /12Z MONDAY THROUGH FRIDAY/... High pressure builds in from the NW into tonight. VFR through the TAF period. Light N/NW flow to start the day, with speeds increasing into mid morning to around 10 kt. Gusts 15 to 20 kt possible from late morning into the afternoon before diminishing by 21Z, but they could also be more occasional. Clear skies prevail much of the day, with some high cirrus moving in tonight. NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty... Gusts may be more occasional this afternoon. .OUTLOOK FOR 12Z TUESDAY THROUGH FRIDAY... Tuesday: VFR. NW winds back SW by late day. Wednesday: Mainly VFR. SW gusts 20-25 kt and showers possible with MVFR at night. Thursday: Chance of MVFR or lower in SHRA. SW/W gusts around 20 kt possible. Friday...VFR. Detailed information, including hourly TAF wind component forecasts, can be found at: https:/www.weather.gov/zny/n90 && .MARINE... Winds and seas will remain below Small Craft Advisory criteria through Tuesday with high pressure over the waters. SW winds will then increase ahead of an approaching cold front. Wind gusts probably approach 25 kt on the ocean Wednesday afternoon and then spread to the rest of the nearshore waters Wednesday night. These winds will continue into Thursday, and there is a chance of gale force gusts late Wednesday night into Thursday morning east of Fire Island Inlet. Will continue to mention this potential in the HWO. Ocean seas build to 5-8 ft Wednesday night into Thursday, and there is a chance for waves on the LI sound to become 3-4 ft. Winds and seas gradually diminishing Thursday night into Friday. Rip Currents: A lack of significant wind or swell under building high pressure will lead to a low rip current risk today through Tuesday. && .OKX WATCHES/WARNINGS/ADVISORIES... CT...None. NY...None.
