SYNOPSIS
A weak surface trough will be in place through Tuesday as upper level disturbances move across. A cold front will approach from the west on Wednesday, and move through late Wednesday night into Thursday morning. High pressure will then follow for late week, and should remain nearby into the upcoming weekend.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/
Convection associated with an incoming shortwave trough has generally resided north and west of the forecast area with a few having made it into Orange County in the Lower Hudson Valley. Latest CAMs support the current activity staying to the north and west. However, cannot rule out something isolated farther east overnight with the passage of the shortwave.

Low temps will be near 80 in NYC, and in the 70s elsewhere.
Some patchy fog may be possible late across areas impacted by earlier tstms.

SHORT TERM /6 AM TUESDAY MORNING THROUGH WEDNESDAY NIGHT/
Heat advy continues into Tue for most of the area. Temps should be a tad warmer but dewpoints a little lower, and this should yield heat index values similar to those of today. There is a chance for afternoon/evening tstms as a mid level shortwave trough moves through. SPC slight risk includes areas NW of NYC, with a marginal risk for the rest of the CWA, as these will be ample instability and vertical shear to support organized cells and line segments capable of producing strong wind gusts.

Another very warm/humid night expected for Tue night, with lows again near 80 in NYC and in the mid/upper 70s most elsewhere.

Extended heat advy into Wed for areas with fcst high temps near or above 90 and heat index values 95 or more (most of wrn sections of Long Island/S CT on west). Uncertainty on meeting criteria is higher for areas to the east, where high temps will only be in the mid/upper 80s but where dewpoints could be higher.

Another round of strong to locally severe convection expected for Wed afternoon and high ahead of the approaching cold front.
Front should enter the area late at night, with low temps from the upper 60s to mid 70s.

LONG TERM /THURSDAY THROUGH SUNDAY/
The main story for the long term will be relief from the high heat and humidity that currently persists over the region.

Key Points:

* A cold front will continue working offshore on Thursday. A few showers, possibly a thunderstorm may linger nearby in the morning with dry conditions becoming likely in the afternoon and evening.

* Daytime temperatures will return to near seasonable levels Thursday and Friday with dew points falling into the lower and middle 60s, potentially upper 50s in spots.

* A slight moderating temperature trend is possible for the upcoming weekend, but highs will still be in the middle to upper 80s with dew points in the 60s.

* Mainly dry conditions should persist into the upcoming weekend.

Upper level trough will continue over the region on Thursday with the cold front pushing offshore. The deep moisture axis and main area of forcing follows, but there could be some lingering showers in the morning, especially closer to the coast. A thunderstorm is possible, but instability will be diminishing as the front pushes further offshore. Model trends continue supporting the end of any showers Thursday afternoon and have trended PoPs lower than the latest deterministic NBM.

The upper trough axis will likely swing across the area Thursday night into Friday morning. Broad troughing will then persist aloft into the start of the weekend, with a more amplified trough passage late in the weekend. The main uncertainty will be how much moisture will be able to return to the region. Forcing continues to look weak, but there is a signal for a weak surface trough or front nearby which could be a mechanism for convection. The deepest moisture and more organized forcing stays largely north. Will continue to keep the forecast dry through the weekend/next Monday, which is in line with the latest model consensus.

AVIATION /03Z TUESDAY THROUGH SATURDAY/
A series of troughs will moves across the area through Tuesday night.

This is mainly a VFR forecast outside of any potential convective complexes working in from the west the next couple of nights.
The first of which is is now looking like it will stay mainly north and west of the terminal overnight. Brief IFR possible at KGON overnight.

Winds mostly SW/S 5-10kt to start, veering to the W/SW overnight with the passage of a surface trough. Winds increase to 10-15kt G20kt on Tuesday. KJFK likely to be sustained around 20 kt late Tuesday afternoon. Expect winds to diminish and veer to the W/SW again Tuesday night following another potential convective complex.

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

A few gust to 25 kt possible Tuesday afternoon.

Amendments likely for timing of showers and thunderstorms Tuesday afternoon/evening.

OUTLOOK FOR 00Z WEDNESDAY THROUGH SATURDAY...

Tuesday Night: A chance of evening showers and thunderstorms, mainly from NYC metro on NW.

Wednesday: VFR to start. MVFR or lower in showers and thunderstorms late afternoon into the evening, with a chance of showers and thunderstorms late at night.

Thursday: Mainly VFR. Chance of showers and thunderstorms.

Friday and Saturday: VFR.

MARINE
A period of SCA conditions is possible, mainly on the ocean, Tuesday night into Wednesday night with increased southerly flow ahead of an approaching cold front. Lingering 5-6 ft seas are possible on Thursday before seas subside into the end of the week.

HYDROLOGY
With a humid air mass in place, any thunderstorms that develop through Wed night will have the potential to produce downpours capable of causing at least minor urban and poor drainage flooding.

No hydrologic impacts are anticipated Thursday through the upcoming weekend.

TIDES/COASTAL FLOODING
There is a moderate rip current risk on the ocean beaches into this evening and then again on Tuesday due to 3-4 ft S swell of 6-8s and S winds 10-15 kt. Seas increase on Wednesday to 5 ft which supports a high rip current risk.
