450 FXUS61 KOKX 081550 AFDOKX Area Forecast Discussion National Weather Service New York NY 1150 AM EDT Wed Oct 8 2025 .SYNOPSIS... A cold front moves east of the area this afternoon. A large dome of high pressure will then build in from tonight into Thursday, settle over the area Thursday night into Friday, then begin to move east on Saturday. A coastal storm could impact the area from Sunday into Monday. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... With FROPA already taken place across much of the area, and the front clearing ern sections towards midday, look for the rain to essentially shut off with the passage of the front for eastern sections, with only a couple of lingering showers early this afternoon even after cold fropa mainly across eastern LI and E So. CT. Skies clear quickly thereafter, with a NW-N wind essentially gusting to 20-25 mph, with a few occasional gusts approaching 30 mph in a few locations. Temps this afternoon will not be nearly as warm as recent days, with highs in the upper 60s/lower 70s. The most noticeably change is with dew point readings into the 50s, and even some dew points into 40s towards and just after sundown. && .SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY NIGHT/... Expect winds to diminish only somewhat tonight, which should limit extent of radiational cooling even under clear skies. Low temps tonight should range from around 50 in/near NYC to the 40s most elsewhere, and reaching the upper 30s in parts of Orange County. Highs on Thu will be the coolest of the season thus far, with highs only in the upper 50s/lower 60s. As the high settles over the area Thu night, clear skies and diminishing winds will promote strong radiational cooling, with low temps in the 40s only in the NYC metro area, with 30s most elsewhere, and sub freezing temperatures across much of the interior where a freeze watch is not in effect, and across parts of the Long Island Pine Barrens. Temps moderate somewhat Fri into Fri night, with highs 60-65 and lows mostly in the 40s to lower 50s, with a few upper 30s in some of the interior valleys. && .LONG TERM /SATURDAY THROUGH TUESDAY/... Key Points: * High pressure will move east on Saturday. * Potential is increasing for a coastal storm to impact the area from Sunday into Monday with strong winds, coastal flooding, and some heavy rainfall. * Temps will be close to mid October norms. Model guidance is trending toward the idea of low pressure developing off the SE coast on Sat moving NNE to a position off the Mid Atlantic coast early next week. Earlier model forecasts had shown an upper ridge developing atop the storm over the Northeast and shunting it more to the south, which would have dealt more of a glancing blow to the area with some gusty winds and little to no rainfall, but they have now trended away from that and toward the idea of a nrn stream closed low digging SE through the upper Great Lakes and OH Valley, preventing upper ridging from shunting the storm south, pulling the storm NNE and even stalling it off the Mid Atlantic coast on Mon as the two systems phase aloft. This increases the potential for strong winds and periods of heavy rain Sunday night into Mon, especially closer to the coast. Reasonable worst case scenarios attm are for winds reaching advy criteria with gusts over 45 mph over a good portion of the area, perhaps closer to warning criteria with gusts closer to 60 mph across eastern Long Island, and 1-2 inches of rain. See the Tides/Coastal Flooding section below for possible coastal impacts. && .AVIATION /15Z WEDNESDAY THROUGH SUNDAY/... High pressure builds in behind a departing cold front. Brief MVFR/IFR the next couple of hours, otherwise VFR as showers come to an end and skies clear form west to east. W-NW winds bcmg NNW by early afternoon. Gusts 20-25kt through this afternoon, with the gusts lingering into this evening for some terminals. ...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty... End time of gusts may be off by a couple of hours tonight for KEWR and KTEB, and there is a chance that gusts are only occasional at most overnight for KLGA and KJFK. .OUTLOOK FOR 12Z THURSDAY THROUGH SUNDAY... Thursday: VFR. N gusts around 20 kt, mainly in the morning. Friday-Saturday: VFR. Sunday: Chance of MVFR or lower in rain. NE gusts 25-35kt. Detailed information, including hourly TAF wind component forecasts, can be found at: https:/www.weather.gov/zny/n90 && .MARINE... SCA expanded to include the central/ern sound where nearshore obs on the CT coast were gusting over 25 kt. SCA continues today for the ocean and south shore bays, with gusts up to 25 kt and ocean seas as high as 5-6 ft. Post-frontal N flow should bring SCA cond to all waters tonight, with gusts 25-30 kt and ocean seas remaining at 5-6 ft. These conditions should last into Thu morning on the ocean. A coastal storm has potential to bring sustained gale force winds and gusts to storm force on the ocean, and gale force gusts elsewhere. Seas could build to 15-20 ft on the ocean, 8-12 ft on the Sound waters E of Orient Point, 5-10 ft at the NY Harbor entrance, and 5-6 ft on the central Long Island Sound. && .HYDROLOGY... Despite the potential for more rain with a coastal storm early next week, there are no hydrologic concerns attm as dry antecedent conditions have prevailed. && .TIDES/COASTAL FLOODING... N flow should limit water levels somewhat on Thu, but as winds turn E on Fri minor flooding looks possible for these areas and also for Newark Bay. Potential for a coastal storm capable of producing widespread moderate flooding and beach erosion on Sunday/Monday has increased, via the combo of high astronomical tides associated with yesterday`s full moon, and surge generated by strong NE flow. && .OKX WATCHES/WARNINGS/ADVISORIES...
