540 FXUS61 KOKX 071807 CCA AFDOKX Area Forecast Discussion...CORRECTED National Weather Service New York NY 207 PM 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 /18Z MONDAY THROUGH SATURDAY/... High pressure builds in from the NW through Tuesday. VFR through the TAF period. NW-N winds 10kt or less will gradually back to a more westerly flow toward evening. There is a chance winds take on a more southerly component at KJFK late, but confidence is too low to mention in the TAF. Light W winds this evening will veer back to the NW tonight, then increase to 7-10kt after 12Z. ...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty... A few gusts 15-18kt this afternoon. .OUTLOOK FOR 18Z TUESDAY THROUGH SATURDAY... Tuesday Afternoon: VFR. NW winds back to SW-S by late day. Wednesday: Mainly VFR. SW gusts 20-25 kt and showers possible with MVFR late at night. Thursday: Chance of MVFR or lower in SHRA. SW/ gusts around 20 kt possible. Friday and Saturday...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.
