133 FXUS61 KOKX 160840 AFDOKX Area Forecast Discussion National Weather Service New York NY 440 AM EDT Thu Oct 16 2025 .SYNOPSIS... High pressure builds into the area through the end of the week and will remain in control through the weekend. A fast moving cold front passes through the area Sunday night into Monday. Weak high pressure then briefly follows before another frontal system potentially impacts the area for the middle of next week. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... High pres near the Great Lakes and low pres over the Atlc will produce cool and breezy wx today with most areas staying in the 50s. Wind chills this mrng in the 30s and 40s. Some mid clouds early, then sunny with deep subsidence. Based on model time heights, wind gusts in the 20-30 mph range seem reasonable, with perhaps a few higher peak gusts due to deep mixing. && .SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY/... High pres builds ewd tngt, but the gradient still should keep winds going for most if not all of the cwa overnight. This will serve to limit frost potential and allow for more homogeneous low temps. Any spots that do decouple will likely see temps blw the NBM numbers. Increasing heights on Fri, and with deep mixing on NW flow, temps should be a few degrees warmer than Thu. With a somewhat dirty ridge building in from the W, should see some high clouds. Winds diminishing in the aftn as the pres grad relaxes. Better radiational cooling cond Fri ngt with light to calm winds. Main limiting factor could be high clouds over the area. Because of these, stuck with the NBM which is too mild for frost advy criteria anywhere. Some patchy frost may be possible in the normally colder sheltered spots. There could also be some patchy fog in the river valleys. Some thicker mid and high clouds on Sat filtering some of the sunshine, but temps should be even warmer nonetheless as the thermal ridge begins to build in from the W. No rain with the next sys still well to the W of the region. && .LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/... The fcst thinking is on track and the NBM was followed. Key Messages: * A progressive upper low tracking across the Great Lakes sends a cold front and showers across the area Sunday night into Monday. * Sunday looks to be the warmest day ahead of the cold front with highs in the upper 60s to lower 70s, which is about 3 to 5 degrees abv normal. Expect readings closer to normal for the remainder of the period. * Another frontal system approaches for the middle of next week. Upper air pattern pointing toward the development of a longwave trough across the east. && .AVIATION /09Z THURSDAY THROUGH MONDAY/... High pressure continues to gradually builds into the region through the TAF period. VFR conditions throughout. Winds will remain northerly through the forecast. Sustained winds around 10 kt until daybreak. Gusts return around 12z-13Z this morning, peaking around 25-30 kt while sustained winds peak around 15-20 kt. Winds gradually subside into the evening and overnight Thursday night. ...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty... An occasional gust higher than forecast can not be ruled out. .OUTLOOK FOR 06Z FRIDAY THROUGH MONDAY... Thursday night: VFR. Winds N G15-25kt. Friday-Saturday: VFR. Sunday and Sunday night: VFR during the day. Possible sub VFR conditions develop Sunday night in showers. Monday: Sub VFR in SHRA early, with possible improvement to VFR during the afternoon. Detailed information, including hourly TAF wind component forecasts, can be found at: https:/www.weather.gov/zny/n90 && .MARINE... NW flow thru Fri with a SCA for all waters today, lasting thru tngt on the ocean. The SCA may need to be extended on the remaining waters thru tngt. Winds and seas decrease subside on Fri. A SCA may be needed, for all or part of the day, particularly on the ocean. Winds and seas blw SCA lcls on Sat, then return flow ahead of a frontal sys may bring winds and seas to SCA lvls for Sun. A SCA will likely be needed behind the sys for Sun ngt and Mon. && .HYDROLOGY... No hydrologic impacts expected thru early next week. && .TIDES/COASTAL FLOODING... N flow gradually relaxes on Friday. Tide levels to reach close to minor thresholds for the most vulnerable spots along the Fairfield CT coastline and along the back bays of S Nassau/SW Suffolk. This may all be dependent on how quickly the N flow relaxes as the offshore flow could mitigate water levels from reaching minor thresholds. With a strengthening S flow and building seas Sunday into Monday, there is a chance that some tidal piling and elevated astronomical tides associated with the new moon of the 20th may lead to some spotty minor coastal flooding in these same areas. && .OKX WATCHES/WARNINGS/ADVISORIES... CT...None. NY...None. NJ...None. MARINE...Small Craft Advisory until 11 PM EDT this evening for ANZ331- 332-340-345. Small Craft Advisory until 11 PM EDT this evening for ANZ335- 338.
