Area Forecast Discussion National Weather Service New York NY 121 AM EDT Mon Sep 27 2021

SYNOPSIS. High pressure south of the area continues to build in through Monday. A cold front moves through on Tuesday into Tuesday night. High pressure builds in and remains to the north and west of the area through at least the beginning of next weekend.

NEAR TERM /UNTIL 6 AM THIS MORNING/. The forecast is mostly on track. Just needed to adjust low temps downward by a few degrees in some spots based on latest trends.

High pressure moves south of the area tonight with slowly diminishing winds. Clear skies and cool conditions will be expected as a NW flow advected drier air into the region. Lows tonight will be in the lower 50s to locally upper 40s for the interior and Pine Barrens Region with areas along the immediate coast mostly 55-60.

SHORT TERM /6 AM THIS MORNING THROUGH 6 PM TUESDAY/. High pressure to the south will slide off the East Coast. A low pressure system in southern Canada drags a cold front across western NY which will begin to the approach the area from the west late in the afternoon. A tight pressure gradient between these two systems will result in a brisk W/SW flow tomorrow with sustained winds 15 to 20 mph and gusts locally up to 30 mph. Other than some gusty winds, conditions will be clear and dry with high temperatures in the middle to upper 70s and possibly low 80s in and around the NYC metro, about 5 to 10 degrees above average.

SW flow ahead of the approaching cold front will allow for a subtle increase in moisture for tomorrow night. This combined with gradually increasing cloud cover will prevent low temperatures from dropping as cool as the previous night. Lows will generally be in the upper 50s to middle 60s. There is a slight chance of showers late in the overnight, mainly after 2AM.

LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/. A cold front moves through the forecast area during the day Tuesday into Tuesday night. There continues to be some timing differences with the passage of the front. All the global models push it off shore by early Tuesday night, with the ECMWF a few hours slower than most other models. There is also uncertainty in the potential for the development of weak low pressure systems along the front, leading to possibly some briefly moderate rainfall. This is seen in both the ECMWF and the NAM. The GFS and Canadian both bring the front through with relatively little rain. In either case, the front is progressive enough and PWATS remain below 2" where flash flooding does not look to be a concern as of yet. There looks to be some surface instability ahead of the front, so kept the mention of isolated thunderstorms during the day Tuesday.

Thereafter, Canadian high pressure builds in from the northwest Wednesday, and remains to the north and west of the area into the beginning of next weekend. A weakening cutoff low over central Quebec will dive south Tuesday night into Wednesday and be situated somewhere over northern New England early Wednesday night. Although there remains uncertainty with models in regards to where the low will track thereafter, models agree with an upper level trough being over or just east the Northeast US into the beginning of next weekend. Model solutions diverge for the second half of the weekend in regards to a frontal system over the middle of the country, but in all solutions, high pressure remains in control across the northeast and mainly dry conditions are expected from Tuesday night through next weekend.

Seasonably cool temperatures are expected from Wednesday onward with high pressure remaining to our west and a persistent north to northwest flow. Highs will generally be in the 60s to around 70, with lows in the 40s and 50s.

AVIATION /05Z MONDAY THROUGH FRIDAY/. Southern high pressure gradually slides off the SE US coast today, with a cold front approaching tonight.

VFR through the TAF period.

SW winds 10 kt or less in the morning, increasing through the morning, and eventually at 15-20 kt with gusts around 25 kt in the aft/early eve. Gusty winds may persist through the eve push for south coastal terminals.

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

Timing of gusts onset early this afternoon and taper off this evening may be off by 1 to 2 hrs. Peak SW gusts to 25 kt likely late aft/early eve, a few gusts to 30 kt possible.

OUTLOOK FOR 06Z TUESDAY THROUGH FRIDAY. Late Tonight. VFR. SW winds subsiding to 5 to 10 kt after midnight. Tuesday. Mainly VFR, with brief MVFR possible in showers. An isolated thunderstorm possible afternoon into evening. Wednesday-Friday. VFR.

MARINE. Small Craft headlines remain up on the ocean waters through Monday for 5 ft seas. Winds are also expected to increase once again Monday late morning and afternoon out ahead of a cold front. Two things of note; 1: There will be a period where seas fall below SCA criteria tonight into Monday before increase once again during the day and 2: There is a chance that small craft advisories may need to be expanded to some of the non- ocean waters for Monday for gusts.

5 ft waves are expected on the ocean waters for Tuesday as a cold front moves through. However, they will slowly diminish through the day, coming below 5 ft by late Tuesday or early Tuesday night. Thereafter, winds and waves are forecast to remain below SCA criteria with high pressure building over the waters.

HYDROLOGY. No hydrologic impacts are expected through next Saturday.

TIDES/COASTAL FLOODING. On Monday, winds W-SW at 15 to 25 kt promote a high risk of rip currents. SE swells decrease slightly on Monday but will still be around 9 sec period. These factors point to the likelihood of a high risk of rip currents at the ocean beaches.

For Tuesday, despite a developing offshore flow, a high risk of rip currents is likely with 2 ft long period ese swells and residual 4 to 5 ft southerly winds waves.

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 PM EDT this evening for ANZ350- 353-355.
