Synopsis for the long island waters and new york harbor.. A warm front moves across the waters into this evening, followed late tonight by a cold front. High pressure returns Friday and Friday night, sliding south of long island Saturday. A frontal system will pass through the area waters late Saturday into Sunday then set up south of the region through Monday with a wave of low pressure passing through the area waters Monday night.

area forecast discussion

552 pm edt Thu may 23 2019

Synopsis
A warm front moves across the region into this evening,
followed later tonight by a cold front. The cold front will move
southeast of long island overnight. High pressure gradually
builds in from the north and west Friday and Friday night. High
pressure slides south of long island Saturday with a weak cold
front bringing showers Saturday night into early Sunday. High
pressure returns for memorial day followed by a warm front
Tuesday.

Near term until 6 am Friday morning
Updated to reflect expected precipitation trends and current dew
point trends. Previous discussion remains valid.

First round of convection is now largely over the ocean waters,
with rain across long island and connecticut. Clouds are
clearing again in its wake, allowing for additional diurnal
heating, though the window for increased surface-based heating
is limited as it's now late in the day. It's likely that more
favorable conditions will exist farther west of the forecast
area.

Regardless, water vapor imagery shows the next vorticity maximum
moving into central new york and pennsylvania. Convection
associated with this secondary wave has largely been shallow
thus far, and surface convergence appears to be limited where
the CU field is increasing, as flow as become more westerly. As
the cold front moves through later in the evening, surface
convergence will increase, and may allow for more additional,
deeper convective initiation development in response to the
forcing for ascent. Mid-level lapse rates upstream remain in the
6.5-7.0 c km range, which combined with the increasing deep
layer shear should be supportive of a few stronger updrafts and
possibly hail. By the time the convection reaches the forecast
area, it's likely that the loss of diurnal heating and the low
level warm advection will strengthen the existing inversion,
based around 850 mb, limiting a more widespread threat for
damaging winds, as storms will largely be elevated. The greatest
potential for any surface- based storms will be across the
lower hudson valley into northeastern nj, though this
instability will be waning given the time of day. As such, the
primary threats into the late evening will be hail and heavy
downpours if any storm can be sustained.

After that, overnight, expecting rapidly decreasing pops with
the cold front moving south of long island with surface flow
becoming more westerly.

Lows tonight are a narrow range from upper 50s to lower 60s
(consensus with greater weight for ecs) considering the
abundant clouds expected and increasing winds late tonight into
early Friday.

Short term 6 am Friday morning through Friday night
Ridging aloft will increase the subsidence so expecting dry
conditions Friday and Friday night along with minimal clouds.

At the surface, parent low pressure moves from near maine out
into the northern atlantic. Steep enough pressure gradient to
make for a breezy day across the region Friday with wind gusts
in the 30 to 35 mph range.

Backing of winds from low to mid levels in forecast soundings
shows cold air advection. Highs forecast on Friday mainly in the
lower 70s, relatively warmer at the coastline with the
downslope NW flow.

For Friday night, more of a spread for low temperatures, upper
40s to upper 50s. Winds decrease and without much clouds,
expecting more radiational cooling.

Long term Saturday through Thursday
High pressure builds from the great lakes Friday night before
sliding offshore late Saturday. This will lead to dry weather
and mild temperatures through Saturday. Lows Friday night will
be in the 50s.

With the high just to the south on Saturday high temperatures
will rise into the 70s, with cooler temperatures along the
coast. Southerly flow will advect in higher dew points, but in
general will be a nice afternoon with some increasing clouds
later in the day.

A weak cold front will approach Saturday night into Sunday.

This could bring a period of showers into early Sunday before
the front pushes offshore by Sunday afternoon.

Heights then rise behind the shortwave that drives the front
east with a ridge building behind for memorial day. That ridge
then becomes quite anomalous with a significant warming trend
likely into mid-week.

An approaching warm front may bring showers Tuesday followed by
dry weather Wednesday and another system on Thursday.

Aviation 22z Thursday through Tuesday
A warm frontal passes this evening and will quickly be followed
by a cold frontal passage tonight.

First round of showers thunderstorms has passed east of the city
terminals and has begun to weaken as it continues east. There
will be a lull in activity for the next few hours with a chance
of a redeveloping showers and storms this evening. Questionable
timing and coverage however and its possible they may be more
scattered. Any showers storms this evening will be capable of
producing brief MVFR ifr. Brief wind shifts to the w-nw may
occur with any storm, but will prevail out of the s-sw.

Otherwise, winds will be from the s-sw this evening with some
gusts to near 20kt. Winds become more W after midnight and then
eventually NW towards Friday morning. Winds on Friday will gust
to near 30kt for most TAF sites.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
