362 FXUS61 KOKX 041436 AFDOKX Area Forecast Discussion National Weather Service New York NY 1036 AM EDT Fri Jul 4 2025 .SYNOPSIS... High pressure builds in Friday then centers over the area Friday night. The high passes offshore Saturday through Sunday while still remaining in control. Lows to our north and south kick high pressure far out to sea by Sunday night. A cold front approaches from the Great Lakes on Monday, passing slowly across the area Tuesday or even stalling in close proximity into midweek. && .NEAR TERM /THROUGH TONIGHT/... *Ideal conditions are expected for Independence Day celebrations. As a cold front continues to push offshore high pressure will build in from the Great Lakes today, centering itself over the area tonight. At the same time, an upper-level trough will push offshore in response to a ridge building in from the west. Overall, dry and sunny weather is expected today. We could not have asked for better weather for any Independence Day festivities and activities you may may have planned. Highs this afternoon will be in the low to mid-80s. This evening`s temperatures will drop back into the 70s under clear skies. Perfect for any planned outdoor celebrations. && .SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/... High pressure will push offshore by Saturday morning but remain in control through Sunday. Simultaneously, an upper-level ridge will continue to build and center itself over the area through this same time period. With sunny, dry conditions expected through the weekend from widespread subsidence, warmer temperatures will naturally follow in July. Highs Saturday will be in the mid/upper-80s followed by Sunday in the upper-80s to low-90s. Increased low level winds from a LLJ should lead to breezy conditions on Sunday into early Sunday night. Given the flow will be southerly, this may also aid in warmer temperatures and higher dewpoints on Sunday. Dewpoints Saturday in the upper-50s to low-60s increase into the mid/upper-60s on Sunday. This will make things feel a little muggier out on Sunday. Surface lows far to our north and south Sunday night along with a flattening ridge aloft will kick surface high pressure out to the east. Despite this, nothing passes close enough to kick off any sort of precipitation, so expecting conditions to remain dry through Sunday night. && .LONG TERM /MONDAY THROUGH THURSDAY/... The NBM was followed with no changes. Key Points: * A cold front approaches the region on Monday and moves across the area on Tuesday. The front eventually stalls south of the forecast area during the middle of the week. * Expect a period of unsettled weather with a chance of showers and thunderstorms each day. Monday appears to the the warmest day of the week with highs in the 80s and lower 90s. Highs for the remainder of the long term will be in the 80s. && .AVIATION /15Z FRIDAY THROUGH TUESDAY/... High pressure gradually builds into the region through the TAF period. VFR. NW winds will continue to increase into the afternoon 10-13 kt. Occasional gusts 17-20 kt are possible. Winds may back to the SW late afternoon/early evening from KJFK to Long Island terminals with potential sea breeze development. Winds become light once again tonight. ...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty... Occasional gusts up to 20 kt possible this afternoon. Wind direction may back to the SW at KJFK 20-22z with a late day sea breeze. .OUTLOOK FOR 12Z SATURDAY THROUGH TUESDAY... Saturday and Saturday night: VFR. Sunday: VFR. SSW gusts up to 20 kt possible Sunday afternoon. Monday-Tuesday: Mainly VFR. Chance of afternoon and evening showers and thunderstorms.

Sub-SCA conditions are expected on all waters Friday through Saturday night. Near-SCA gusts are expected on Sunday with seas on ocean waters climbing to 4 ft Sunday night. Conditions are expected to remain below SCA levels Monday and Tuesday. SCA conditions may return for the middle to end of next week with seas building to 5 ft or greater. && .HYDROLOGY... No widespread hydrologic impacts anticipated through the middle of next week. && .TIDES/COASTAL FLOODING... A lingering southerly swell of 2-3 ft 6-7s will produce mainly a low rip current risk on Friday, except for a moderate risk for the beaches from Smith Point to Montauk Point. A low rip current risk is expected for all beaches on Saturday. && .OKX WATCHES/WARNINGS/ADVISORIES... CT...None. NY...None. NJ...None.
