Area Forecast Discussion National Weather Service New York NY 744 AM EDT Sat Sep 18 2021

SYNOPSIS. Tropical Storm Odette well offshore will track northeast across the western Atlantic today. Meanwhile, a weakening cold front will pass through the area tonight. Strong high pressure builds in Sunday through Monday, then gradually works offshore through midweek ahead of an approaching cold front. The front is forecast to move across the region Wednesday night into Thursday. High pressure may return at the end of the week.

NEAR TERM /THROUGH TONIGHT/. No changes with this update.

Latest low cloud/fog satellite imagery along with surface observations continue to show widespread low clouds across the area. There is some patchy fog as well inland. Improvement is forecast later this morning with the onset of daytime heating which will allow the clouds to lift and dissipate.

Thereafter, looking for a partly to mostly sunny day as a cold front approaches from the northwest. The circulation between Odette offshore and weakening high across New England will allow for a gradual wind shift to the W/NW ahead of the cold front late this afternoon. Thus, weak convergence along the cold front coupled with marginal instability and weak shear should only result in isolated showers or thunderstorms this afternoon into early this evening. The cold front passes offshore before midnight.

Much of the area will get into the lower 80s with the NYC metro possibly getting as high as the mid 80s.

Behind the cold front tonight, NW flow will filter in some drier, cooler air, with lows in the upper 50s inland, and the 60s along the coast. This is still on the unseasonably warm side.

SHORT TERM /SUNDAY THROUGH MONDAY/. High pressure builds across the region this period with temperatures returning to seasonable levels by Monday. Conditions will also remain dry with plenty of sun.

N winds on Sunday will gradually veer around to the NE Sunday night and then southeast on Monday as the high works to the New England coast.

LONG TERM /MONDAY NIGHT THROUGH FRIDAY/. No significant changes in the long term for this update.

Global models are in fairly good agreement as to the general pattern in the long term. Strong high pressure to the NE of the area in the beginning of the week allows for generally clear skies and dry conditions through midweek. By late Tuesday, the high slides east allowing for a primarily S/SE flow which will bring some moisture back into the area. Meanwhile, a potent trough approaches the area from the west.

This produces a large surface low pressure system and strong cold front that is poised to move through sometime in the middle of the week. Timing of the frontal passage is in slightly better agreement with models generally slowing down the frontal passage to sometime on Thursday. That being said, there will still be a chance for showers late Wednesday with moist southerly flow over the area ahead of the front. Instability looks to be too weak to include the mention of thunder at this time. High pressure looks to move in in the wake of the front, but how quickly the front pushes out of the area is a bit uncertain as the ECMWF and CMC occlude a low to our west and slow the progression of the front over the area.

High temperatures will generally be about average through much of the long term with temperatures in the low to middle 70s each day. Friday looks to be the coolest day with high temperatures in the upper 60s and maybe low 70s, but this will depend on if the front passes by Thursday night.

Low temperatures each night follow a similar trend through the long term with lows in the middle 50s to low 60s Monday night through Wednesday night. Behind the front, drying air and flow off the continent will allow for lows dropping into the low 50s (and possible upper 40s) for the Interior to low 60s for the coastline.

AVIATION /12Z SATURDAY THROUGH WEDNESDAY/. Tropical Storm Odette well east of the Delmarva will move farther northeast well out into the Western Atlantic through the TAF period. A weak front approaches the area from the northwest this afternoon with the low chance of SHRA. Did not include in the TAFs as probability is too low.

Low stratus remains for much of the eastern portion of the area with MVFR and IFR ceilings lingering for the next several hours. The NYC terminals are already VFR as stratus has scattered out. Outlying terminals become VFR through 15Z and remaining VFR through the TAF period.

N winds 5-10kt eventually become more NW or W this afternoon, with possible brief weak sea breeze development mid to late afternoon for some terminals (JFK, BDR, GON). Winds shift back N tonight.

. Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty .

Amendments possible for timing of improving categories this AM and the presence of any showers this afternoon. Some uncertainty in development and inland extent of sea breeze.

OUTLOOK FOR 12Z SUNDAY THROUGH WEDNESDAY. Sun. VFR with NNW flow. Mon-Tue. MVFR possible at times, especially in the mrng. Wed. MVFR or lower possible as a strong cold front approaches.

MARINE. Tropical Storm Odette will continue to track well north and east away from the waters through the weekend. See the National Hurricane Center for the latest information on Odette.

Long period E/SE swells from the low will likely keep seas on on the oceans waters at 5-6 ft through the first half of the night, possibly lingering into Sunday morning. Winds on the backside of Odette will generally be northerly into Sunday and below SCA criteria.

High pressure building over the waters Sunday through early next week will lead to conditions below Small Craft Levels. Winds and seas will build ahead of an approaching cold front Wednesday night into Thursday. Conditions at this time should stay below SCA levels until at least Thursday afternoon.

HYDROLOGY. No hydrologic impacts are expected through Tuesday. A frontal system will then bring rainfall to the region late Wednesday into Thursday. It is too early at this time for specific rainfall amounts due to some uncertainty with the evolution of the system.

TIDES/COASTAL FLOODING. There is a high risk of rip currents through this evening for the ocean beaches due to a continued SE swell of 5 to 6 ft. The swell subsides on Sunday, but there will be a moderate risk of rip currents.

In addition, the combination of the SE swells and an approaching full moon could bring waters levels close to minor coastal flood benchmarks during the evening high tide cycles tonight and Sunday. The south shore back bays of Nassau would be most susceptible due to piling of water from the swells. Right now, water levels are forecast to remain just below.

OKX WATCHES/WARNINGS/ADVISORIES. CT . None. NY . High Rip Current Risk through this evening for NYZ075-080-081- 178-179. NJ . None. MARINE . Small Craft Advisory until 6 AM EDT Sunday for ANZ350-353-355.
