| Area Forecast Discussion National Weather Service New York NY 1047pm EDT Thu April 2 2026 .WHAT HAS CHANGED... No significant changes. .KEY MESSAGES... 1. Potential dense fog late tonight into Friday morning mainly for coastal areas. 2. Showers on Sunday could produce local downpours that would lead to brief nuisance flooding at most. .KEY MESSAGE 1... Warm front advances from the south late tonight. Associated lift ahead of the front with shallow moisture could produce light rain and drizzle. Fog will then become more likely late tonight into Fri morning with the wind flow turning more SE and warmer dewpoints advect over colder sea surface temps. Confidence is not high regarding how low the surface visibility will be reduced as well as actual onset of lowest vsbys, however some guidance suggests there could be areas to widespread instances where the visibility falls close to 1/4 mile. No advisories planned at the moment, but this will have to be monitored. Highest chances of dense fog will be toward the coast. .KEY MESSAGE 2... Heigheights aloft fall by the latter half of the weekend as ridging shifts offshore ahead of digging trough into the Eastern US. Surface low pressure deepens as it drives through the Great Lakes, with attendant fronts lifting toward the region, bringing the next widespread rainfall. Warm front approaches Saturday, with a few showers possible, before another round arrives ahead of the cold front on Sunday. A few embedded thunderstorms can't be entirely ruled out with the activity, but instability will be lacking, so not anticipating a local severe weather threat. Global guidance progs PW up to 1.5 inches though, toward the top of climo this time of year, so sufficient moisture to tap into that could translate into localized downpours ahead of the boundary. Impacts likely limited to the possibility of some minor urban and poor drainage flooding at most, mainly Sunday afternoon. Overall, Quantitative Precipitation Forecast is light given the progressive nature of the system, averaging at or under a quarter of an inch. Cold air advection kicks in behind the front, and the milder air mass in place over the weekend will be replaced by a more seasonable one, with afternoon temperatures likely in the 40s and 50s for most through mid next week. Marine Ocean seas continue to run 6-9 ft which is 1-2 ft above NWPS forecast, highest west due to persistent ENE flow up to 20 kt with some gusts 25-30 kt. With this in mind, it now appears that any lull daytime Fri will be brief and that seas will build back to 5-6 ft by late Fri afternoon into Fri night or early Sat morning as winds shift S after warm frontal passage and increase to near 20 kt. Dense fog may be possible late tonight into Fri morning as a warm front approaches. Chose not to issue the advy until timing of onset of lower visibilities becomes clearer. SCA (Small Craft Advisory) cond are also likely Sat night through Sunday as a frontal system moves through, with gusts 25-30 kt and ocean seas 7-10 ft likely. Potential for gales on the ocean looks low due to a strong sfc-based inversion and LLJ only 50-55 kt. The LLJ strengthens to our east Sunday afternoon so any gales are more likely to our east. Ocean seas then likely linger above 5 ft through at least the first half of Monday. NOAA New York NY Office: Watches - Warnings - Advisories CT...None. NY...None. NJ...None. Marine Small Craft Advisory until 6am EDT Saturday for ANZ350-353- 355. |
