SYNOPSIS. A cold front approaches tonight and passes through Tuesday afternoon into evening. This will be followed by high pressure on Wednesday. Another cold front will move through Wednesday night into Thursday. High pressure will then build in and remain to the north and west through the weekend. A frontal system will approach late Sunday into the beginning of next week.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/. Increased cloud cover over the next few hours based on the latest obs and trends. Otherwise, only minor changes made with this update, mainly hourly temperatures.

Partly to mostly cloudy with a shower possible toward sunrise, mainly north and west of the city. Lows tonight should range from the upper 50s in the interior valleys to the mid 60s in NYC. Somewhat breezy at the coast before midnight, but winds should slowly subside as a low level jet weakens and shifts east.

SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/. Showers/tstms expected with the cold frontal approach/passage, mainly in the afternoon/early evening with peak heating/instability. A few storms, mainly in NE NJ, in/around NYC, and across western Long Island, could be on the strong side, with gusty winds and small hail, given MLCAPE increasing to around 1000 J/kg and mid level flow 30-35 kt with unidirectional shear via deep layer WSW-W flow.

For temps on Tue, went 1-2 deg above highest MOS guidance numbers, with highs again reaching 80 in NE NJ, and the mid/upper 70s elsewhere. A drying N flow after cold fropa should drop temps to the mid 40s well inland, and to the mid 50s in/around NYC and along the coast.

LONG TERM /WEDNESDAY THROUGH MONDAY/. High pressure will build in at the surface Wednesday morning as a northwest flow sets up behind the cold front. In the upper levels, a cut of low will head south from southern Quebec and be situated near the Gulf of Maine by midday Thursday. During this time frame, another surface cold front looks to move through the area Wednesday night into Thursday morning. There is little moisture to work with, and all that will accompany the frontal passage is just a minor wind shift. However, a vorticity max spins around the west side of the upper low, and with the cold pool aloft and surface heating, there may be enough instability for some isolated showers late Wednesday night into Thursday.

Any showers will end after sunset Thursday evening, and the upper low quickly pulls away from the region Thursday night. Canadian high pressure continues to build in at the surface through Friday, with the axis of the upper level trough to our east.

Thereafter, high pressure at the surface settles over the area or just to our southwest as a frontal system develops over the Plains states and slowly moves east through the weekend, with the flow aloft becoming more zonal. There is a great deal of uncertainty, especially for the second half of the weekend into the beginning of next week in regards to placement of any fronts and low pressure systems

A persistent northwest flow will mean seasonably cool temperatures for this time period. Highs will generally be in the 60s to around 70s with lows in the 40s and 50s.

AVIATION /02Z TUESDAY THROUGH SATURDAY/. A cold front approaches tonight and moves through the terminals Tuesday.

VFR through the TAF period. There may be scattered showers after around 10-14Z Tuesday. Better chances of showers and a low chance of thunder starting mid-afternoon.

SW winds 10 to 15 kt with occasional gusts around 20 kt early on, slowly diminishing through the night - eventually W to SW 5 to 10 kt overnight.

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

Occasional gusts up to around 20 kt possible until 04z.

OUTLOOK FOR 00Z WEDNESDAY THROUGH SATURDAY. Tuesday night. Showers possible east of the city terminals early on, otherwise VFR. Wednesday-Thursday. VFR. Slight chance of showers east of the NYC metro terminals Wednesday night and Thursday. Friday through Saturday. VFR.

Detailed information, including hourly TAF wind component forecasts, can be found at: https:/www.weather.gov/zny/n90

MARINE. Low level jet over the eastern waters should be on a weakening trend and shifting east from this point on. Will leave Gale Warning up east of Fire Island Inlet for the time being, but will probably be able to cancel and replace with a SCA before the night is through. Seas on the ocean range 5-8 ft.

SCA otherwise in place for all other waters except NY Harbor and western Sound for at least a portion of tonight.

SCA conds (mainly lingering 5+ ft seas) expected Tue morning mainly E of Fire Island inlet.

After cold fropa, N winds may gust up to 25 kt late Tue night into early Wed morning, with ocean seas on the outer eastern waters approaching 5 ft.

Generally sub SCA conditions expected thereafter through Saturday. Ocean seas could build to 5 ft on the ocean Sat night.

HYDROLOGY. No hydrologic impacts are expected through next Saturday.

TIDES/COASTAL FLOODING. For Tuesday, despite a developing offshore flow, a high risk of rip currents is likely with 2-ft long period ESE swells and residual 4-5 ft southerly wind waves.

For Wednesday, an offshore flow continues. Any residual waves diminish to 2-4 ft and will come out of the northeast, which is not a favorable direction. However, 1 ft waves with a long period (13 sec) out of the SE are expected, leading to a moderate risk of rip currents.

OKX WATCHES/WARNINGS/ADVISORIES. CT . None. NY . High Rip Current Risk through Tuesday evening for NYZ075-080- 081-178-179. NJ . None. MARINE . Small Craft Advisory until 2 AM EDT Tuesday for ANZ331-332-340- 345. Small Craft Advisory until noon EDT Tuesday for ANZ355. Gale Warning until 6 AM EDT Tuesday for ANZ350-353.
