| Area Forecast Discussion National Weather Service New York NY 344pm EDT Tuesday May 26 2026 .WHAT HAS CHANGED... No significant changes. .KEY MESSAGES... 1) Another warm day on tap Wednesday, with a late day shower or thunderstorm possible. 2) Cooler for the end of the week with multiple disturbances dropping south across the Northeast. 3) Moderate risk of rip currents Wednesday. .KEY MESSAGE 1... An amplifying shortwave trough dropping south across eastern Canada will carve out an upper trough across the Northeast for the end of the week into the weekend. This will be preceded by a cold frontal passage Wednesday afternoon and early evening. Before that happens through, another warm day will be on tap for Wednesday with most locations away from the immediate shore getting up into the 80s. Highs are forecast to top out about 3 to 5 degrees warmer than Tuesday. There is some uncertainty in the temperature forecast due to a canopy of mid and high level clouds expected across the area. The latter is associated with moisture rounding the subtrop ridge over the western Atlantic. At the same time, height falls from the aforementioned upper trough will block much of the southern branch energy from advancing north, but there could be a few showers near or just southwest of NYC and LI toward daybreak Wednesday. Thus, the extent of cloud cover limiting daytime heating is in question. However, the spread in the NBM for highs on Wednesday has decreased the last 24h. Widely scattered convection is also a possibility Wednesday afternoon and evening as the cold front moves through the area. NBM still wants to keep it dry, but with marginal instability and modest deep-layer shear, have kept thunderstorms in the forecast. Storm Prediction Center has the area in a general thunderstorm outlook. Dry air in the mixed layer and a mid level cap are limiting factors. CAMs support limited coverage at this time. .KEY MESSAGE 2... Temperatures return closer to normal for the end of this week into early next week. Upper trough will remain across eastern Canada and the Northeast during this time. Multiple disturbances in the NW flow aloft will drop south across the area with a chance of showers and possibly a low- topped thunderstorm. The best chance looks to be Friday night into Saturday. While there are timing issues with these disturbances, widespread rain stays mainly north and east of the area. Eastern portions of CT and LI have chances of about 30 to 50 percent, but falling off to the west. This by no means will be washout. .KEY MESSAGE 3... Moderate risk of rip currents likely on Wednesday with residual 2-ft SE swell, and 2-ft S wind waves. Marine There is a chance for marginal SCA (Small Craft Advisory) conditions Saturday afternoon and night in a northerly flow. Best chance looks to be east of Moriches Inlet. Otherwise, expecting relatively quiet conditions. NOAA New York NY Office: Watches - Warnings - Advisories CT...None. NY...None. NJ...None. Marine None. |
