232 FXUS61 KOKX 241121 AFDOKX Area Forecast Discussion National Weather Service New York NY 721 AM EDT Wed Jun 24 2026 .WHAT HAS CHANGED... No significant changes made. && .KEY MESSAGES... 1. Unsettled weather returns late Thursday through Saturday. Severe and flash flooding impacts are not anticipated at this time. 2. Hotter temperatures probable for next week. Too early for high confidence regrading potential heat impacts. && .DISCUSSION... .KEY MESSAGE 1... Weak low pressure over the Great Lakes on Thursday tracks east and passes to our north on Friday. This will send a warm front through the area Thursday night, followed by a cold front most likely during Friday night. A wave of low pressure along the cold front then passes to our south on Saturday. Showers possible as early as late day/early evening Thursday, but most likely during Thursday night and once again during Friday night into early Saturday. CAPE and shear profiles are not supportive of severe weather during the entire period, but perhaps there`s some strong wind gust potential in anything the manages to push in from the west by sunset Thursday. Strong gusts are also possible in any thunderstorms Friday afternoon/early evening. No strong signals yet for flash flooding during the period. PWATs forecast to increase Friday night into Saturday. Models generally keep the deepest moisture not too far to our south, so trends regarding how far south the cold front sags during this period need to be monitored. The aforementioned wave of low pressure along the front could end up farther north and increase the flooding potential. .KEY MESSAGE 2... Models generally agree with a longwave ridge building to our west during Tuesday. Just how close the ridge axis gets to us before breaking down is in question. Given progged global model and LREF 850mb temps, along with uncertainty regarding any potential convection spilling over the ridge into our area, agree with WPCs downward adjustment from NBM for Tuesday`s high temperatures. Temperatures combined with dewpoints would likely fall short of any advisory thresholds, but given the uncertainty of an event 7 days away, trends will need to be watched, especially for later on in the week when the heat may build further. && .AVIATION /12Z WEDNESDAY THROUGH SUNDAY/... Low pressure located to our south will pass east of the area as it exits through today. High pressure gradually builds into the area through the TAF period. VFR through the TAF period. NW winds around 10 kt this morning. Wind directions will become more westerly by the afternoon and early evening. Some may may briefly go WSW. Tonight, winds diminish to 5 kt or less, becoming northerly again. Tomorrow, winds increase to 10 kt from a southerly direction. ...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty... Amendments not expected. .OUTLOOK FOR 12Z THURSDAY THROUGH SUNDAY... Thursday: Mainly VFR. MVFR or lower possible at night with increasing chances of showers, becoming likely late north and west of NYC. A chance of thunderstorms. S wind gusts 15-20 kt afternoon into eve. Friday-Saturday: MVFR or lower possible with showers at times. A chance of thunderstorms. Sunday: VFR.
