Synopsis for the long island waters and new york harbor.. High pressure builds in from the west into Monday, then slowly slides offshore as hurricane maria slowly tracks north, then northeast off the southeastern and mid-atlantic coasts through Wednesday. Please refer to national hurricane center products for more details on maria. A cold front will approach from the west Wednesday night, then cross the area Thursday morning. High pressure then builds in behind the front.

area forecast discussion
national weather service new york ny
724 am edt Sun sep 24 2017

Synopsis
High pressure will prevail across the area through the first
half of the week. Meanwhile, hurricane maria is forecast to
track north and pass east of the carolinas on Wednesday before
getting kicked out to the east by an approaching cold front. The
front is forecast to move through the region Thursday, followed
by high pressure for the end of the week. Refer to the latest
advisories from the national hurricane center for the official
forecast on maria.

Near term until 6 pm this evening
Based on latest satellite imagery and observations, patchy fog
is limited to SE ct and eastern li. Any fog should dissipate
quickly with the onset of daytime heating.

Otherwise, another very warm day across the region with a good
chance of record highs being met at multiple locations, ranging
from the 80s at the coast to the lower 90s across the interior.

Readings were several degrees above MOS on Saturday and will
continue that trend. See the climate section below for records.

There is a high rip current risk at the ocean beaches through
this evening due to increasing southerly swells from maria.

Short term 6 pm this evening through 6 pm Monday
There is the potential for areas of fog to develop tonight. The
nam is very aggressive with the low-level moisture beneath the
inversion, while the GFS is drier. These are typical known
biases and with this being the first night of return flow
conditions, prefer to only go patchy in nature. Still though,
the longer days and a humid airmass could result in a more
widespread event.

Warm heights aloft with a anomalous upper high centered over
the area will continue the string of unseasonably warm days
into Monday. However, an onshore flow will knock highs down
several degrees. In addition, humidity levels will creep up as
well. Airmass will be too stable to support any convection.

Swells from distant hurricane maria will likely produce a
high rip current risk on Monday.

Long term Monday night through Saturday
The highly amplified upper air pattern across the lower 48
begins to break down this period as the upper trough lifts out
across the northern plains and into and into eastern canada by
Thursday. Additional pacific shortwave energy eventually gets
loaded into the backside of the trough at the end of the week.

A cold front passes through the area Thursday with a reinforcing
shot of cooler air on Friday and a return to seasonable
temperatures, if not below by the weekend.

Hurricane maria will track slowly north through the week. The
global models are in all good agreement with taking the system
east of the outer banks of north carolina Wednesday before
it gets kicked out to the east by the aforementioned upper
trough and associated cold front. Refer to the latest
advisories from the national hurricane center for the official
forecast on maria.

Warm heights aloft and subsidence will result in an unseasonably
warm conditions Tuesday and Wednesday. There continues to be a
low chance of showers Tuesday night through Thursday as
moisture works in ahead of maria and the upper ridge break down
with the approach of the upper trough and cold front. High
pressure builds in for next weekend. In addition, areas of fog
and lows clouds will become more likely Tuesday and Wednesday
mornings due to a prolonged east flow. Northerly winds return
behind the cold frontal passage on Thursday.

Due to long period swells from maria, there is likely to be a
high rip current risk through the week.

Aviation 12z Sunday through Thursday
High pressure builds in from the west into Monday morning.

Vfr through at least 6z. There is the potential for MVFR fog
outside of the city terminals after 6z. There is a chance of ifr
or lower conditions at kgon with a very low chance at
kisp khpn kbdr kswf as well late tonight.

Winds become n-ne at under 10 kt by mid morning at all
terminals except kswf, where this should occur by early
afternoon and at khpn (ongoing). Seabreezes are then expected
at all terminals but kswf, starting around midday at ct
terminals, early afternoon kjfk kisp and mid-late afternoon
elsewhere. Light and variable winds return at all terminals late
by early this evening.

Outlook for 12z Monday through Thursday
Monday Most likelyVFR. There is a low chance for MVFR-ifr
conditions at eastern terminals and kswf early Monday morning.

Monday night-Thursday MVFR or lower conditions and scattered
showers are possible.

Marine
Long period swells will produce seas of at least 5 feet (initially
over just southern portions) of the coastal ocean waters through at
least Thursday night. (except starting late this afternoon for the
coastal ocean waters W of fire island inlet). As a result now start
the small craft advisory for hazardous seas at 20z W of fire island
inlet (already ongoing east of there) and have extended the headline
in all 3 zones through the day on Monday.

A weak pressure gradient will remain over the waters through at
least Thursday, with winds around 10 kt or less through then. The
pressure gradient tightens Thursday night, and when coupled with
cold air advection, could result in winds Thursday night up to 15-
20kt with possibly some gusts of 25-30kt.

Hydrology
No hydrologic problems anticipated through the end of next week.

The following are record high temperatures for Sunday

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
