| Area Forecast Discussion National Weather Service New York NY 143am EDT Monday May 11 2026 .WHAT HAS CHANGED... No significant changes. .KEY MESSAGES... 1) Showers likely across Long Island and SE CT overnight with isolated to scattered elsewhere. 2) Unsettled weather expected mid to late week with the highest probability of showers late Wednesday into Thursday. KEY MESSAGE 1... Cold front will pass through the area this evening. A weak wave should form along the front in advance of a 250 mb jet streak approaching from the Ohio Valley. The wave will pass to the south and east. Showers may become a bit more numerous, especially from across Long Island and then into southeast Connecticut. CAMs still support this scenario for likely Probability of Precipitation across these areas tonight into the early morning hours. The showers will largely be on the light side, although a few pockets of brief moderate rates are possible. Average Quantitative Precipitation Forecast is generally around a tenth of an inch or less. KEY MESSAGE 2... Low pressure and its associated mid level shortwave will dive SE into the Great Lakes region Tuesday night. This system will carve out a deeper mid-upper level trough over the eastern States mid to late week. The low pressure and its associated frontal system will likely impact the area late Wednesday into Thursday. Modeling has differed over the last few days with how quickly the mid-upper trough will move across the northeast. The trough may not completely push offshore until at some point on Friday. Unsettled conditions are expected by late Wednesday and continuing into Thursday. There is a chance these conditions may persist into Friday, depending on the timing of the upper trough. Showers with this system may arrive Wednesday afternoon, with the most likely time for organized showers Wednesday night into Thursday. Chances for showers could linger Thursday night into Friday. Consensus approach argues for rainfall of around one half inch, but localized amounts could be higher in any convection, late Wednesday into Thursday. Any rain beyond Thursday likely will be scattered and with light amounts. Marine A SCA (Small Craft Advisory) is in effect on the ocean through 2 am west of Moriches Inlet and to 8 am east of Moriches Inlet. Swells 5-6 ft are likely to continue during this time frame. Conditions will then remain below SCA (Small Craft Advisory) levels through early Wednesday. An approaching cold front will increase winds and build seas, bringing the next chance for 25 kt gusts and 5 ft seas on the ocean Wednesday afternoon into Wednesday night. Winds on the non-ocean may also reach 25 kt. These conditions could linger into early Thursday, but subside below SCA (Small Craft Advisory) to end the week. NOAA New York NY Office: Watches - Warnings - Advisories CT...None. NY...None. NJ...None. Marine Small Craft Advisory until 8am EDT this morning for ANZ350- 353. Small Craft Advisory until 6am EDT early this morning for ANZ355. |
