| Area Forecast Discussion National Weather Service New York NY 729am EDT Monday September 14 2026 .WHAT HAS CHANGED... No significant changes were made to the forecast during this update. .KEY MESSAGES... 2) Dry and sunny conditions through midweek, with a gusty N/NW flow today. No hazardous weather expected. 3) Next chance of rain is Thursday into Friday with a cold frontal passage and then potentially again for the second half of the weekend. .KEY MESSAGE 1... With the frontal passage this morning, brief light showers are possible across eastern Long and eastern CT through the next hour or so. Behind the cold frontal passage, high pressure will build in and remain in control through midweek. Gusty winds are expected. There may be initial gusts with the cold front of around 20 kt and then with deep mixing 20-25 kt are possible during the afternoon. Went a few kt higher than much of the guidance given recent events of guidance under doing cold advection in a N/NW flow. Additionally, with mixing and the downslope flow, went higher than the NBM and closer to MOS with highs today. This gives highs in the mid to upper 70s for most. Drier air will also be filtering into the area, which will give the air a comfortable feel. Tonight looks to be ideal radiational cooling conditions for the interior. Along the coast a tighter pressure gradient in the NE flow will likely be enough to stop the Pine Barrens and other usually cooler locations from completely decoupling. Mid to upper 40s expected across the interior for lows tonight. .KEY MESSAGE 2... The next chance of rain looks to be with a cold frontal passage late Thursday into Friday which has trended drier. No impacts are expected at this time. A more widespread rainfall is possible the second half of this weekend with a frontal system moving in from the west. The guidance is not consistent on how it handles this system and Probability of Precipitation are capped around 30 percent at this time. Marine Gusty winds behind a cold front are expected this morning through the afternoon. Gusts will peak generally between 20 and 25 kt. Kept the SCA (Small Craft Advisory) for the eastern two ocean zones. If observed winds start coming in a bit higher there is potential for a SCA (Small Craft Advisory) to issued for other waters. Thereafter, winds and waves stay below SCA. Rip Currents... Low rip current risk today and Tuesday for all ocean beaches. Today, winds will be offshore with only a 2 ft S/SE swell. On Tuesday, the flow will be out of the east with an even weaker swell. RCMOS and local guidance were in agreement with a low risk. NOAA New York NY Office: Watches - Warnings - Advisories CT...None. NY...None. NJ...None. Marine Small Craft Advisory until 2pm EDT this afternoon for ANZ350- 353. |
