212 FXUS61 KOKX 281753 AFDOKX Area Forecast Discussion National Weather Service New York NY 153 PM EDT Mon Jul 28 2025 .SYNOPSIS... High pressure builds into the area today and Tuesday, moving offshore Tuesday night. A cold front approaches Wednesday. The front moves through Wednesday night, with a frontal wave developing along it and tracking nearby through Thursday. High pressure builds in from the Great Lakes Friday into next weekend. && .NEAR TERM /THROUGH TONIGHT/... * Today will be the first day of what will be a 3 day heat wave for much of the region. * Heat Advisories remain in place today through Wednesday. Surface high pressure and upper level ridging builds into the area today. 850mb temperatures climb to 19C for parts of the area. This should result in surface temperatures reaching the middle and upper 90s across the NYC/NJ metro area, with lower to middle 90s across the remainder of the region. The only exception will be right along the coast across the far eastern sections of the region, where temperatures may only stay in the upper 80s. The combination of these temperatures and dew points once again rising into the middle to upper 60s and lower 70s, Heat index values should reach the middle and upper 90s to near 100. Otherwise, it will remain dry today, with mostly sunny skies. Dry conditions continue into tonight. Overnight temperatures wont fall much, with lows in the 70s. The warmest spots will be across the NYC/NJ metro area with upper 70s expected. && .SHORT TERM /TUESDAY THROUGH WEDNESDAY/... * Heat advisories remain in effect for Tuesday and Wednesday. Expect Heat index values to be in the middle and upper 90s to lower 100s. Surface high pressure and upper level ridging continues into Tuesday and Tuesday night. 850mb temperatures rise a couple more degrees, to around 21-22 C. Expect surface temperatures to be a few degrees warmer with highs in the mid to upper 90s, potentially hitting 100 across portions of Northeastern New Jersey. A couple of record high temperatures are possible. See the CLIMATE section for details. The higher temperatures Tuesday with similar dew points will result in heat indices of 95 to 104. A few locations may reach 105, however, with the limited areal coverage a Heat Warning is not expected to be needed. It appears that the ridging aloft will now continue into Wednesday afternoon. As a result, the heat and humidity should stick into Wednesday. Once again, we are looking at heat indices reaching the middle and upper 90s to lower 100s. Still feel that conditions will remain below extreme heat warning criteria. A cold front approaches late Wednesday. Showers and thunderstorms are possible Wednesday afternoon into Wednesday evening. Confidence not high with respect to the severe potential at this time, however, any storms that do occur will be capable of heavy downpours. && .LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/... Key Points: *Showers and thunderstorms accompany a cold frontal passage Wednesday night, and some of the thunderstorms could be strong to severe and produce locally heavy downpours that lead to flooding, mainly in urban and poor drainage areas. *Heat breaks behind the front on Thursday, but conditions remain unsettled with additional showers and thunderstorms likely as a wave of low pressure develops along the nearby front. *High pressure builds towards the area Friday and settles over the region this weekend, bringing drier, cooler conditions. && .AVIATION /18Z MONDAY THROUGH SATURDAY/... High pressure builds into the region today and into Tuesday. VFR thru the day at all terminals. N/NW around 10-12 kt will be overtaken by seabreezes at the coastal terminals this afternoon. Weak flow persists tonight, and general flow turns westerly Tuesday. ...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty... Timing of seabreezes (southerly winds) may be off by an hour or two. .OUTLOOK FOR 18Z TUESDAY THROUGH SATURDAY... Tuesday: VFR. Wednesday: Mainly VFR. A chance of showers and thunderstorms late in the day and at night. Wed Night thru Thursday: Showers with MVFR possible. Friday and Saturday: VFR. Detailed information, including hourly TAF wind component forecasts, can be found at: https:/www.weather.gov/zny/n90 && .MARINE... Conditions will remain below SCA levels through Wednesday. A cold front moves across the waters Wednesday night through Thursday. Increased winds behind the front could allow seas to build toward 5 ft on the ocean late this week, primarily Friday. && .HYDROLOGY... There are no hydrologic concerns through the day Wednesday. Locally heavy downpours are possible with a cold front and frontal wave Wednesday afternoon/evening and Thursday, but confidence in potential impacts remains low at this point. && .TIDES/COASTAL FLOODING... There is an overall low rip current risk for ocean beaches today and Tuesday with only 1 to 2 feet offshore wave heights and the absence of a wind wave contribution. && .CLIMATE...
