Synopsis
Low pressure will persist to the west early this week, while
offshore high pressure builds slowly westward. An associated
frontal boundary will remain to the west through much of the
week, with an extended period of unsettled weather with the
chance of showers and thunderstorms each day. A prolonged period
of southerly flow will also result in high humidity.

Near term until 6 am Monday morning
Seeing only widely sct showers on radar at most mainly N of nyc.

While air mass does have sfc-based instability, most of that
instability is above h8, so without an organized source of lift
coverage should be limited through the rest of the daylight hrs.

Do expect that to change tonight, especially out east, as
heights rise aloft over the western atlantic and push rain
band and associated mid level forcing back westward from the
atlantic. It will remain very muggy with temps and dewpoints
in the 70s.

A high risk of rip currents continues at the ocean beaches today
due to large breaking waves of 4-7 ft in the surf zone.

Short term 6 am Monday morning through Monday night
An unsettled pattern will be in place the next few days as the
region remains sandwiched between a deep upper trough over the
eastern us and downstream high pressure stationed offshore and
building slowly westward. This setup will result in deep
tropical moisture and uncomfortably high dewpoints.

Periods of showers and thunderstorms are expected into Monday
night. Main areas of activity should be across eastern ct long
island, also from nyc north west, during Monday afternoon, where
instability looks to be maximized at least into early afternoon,
and as multiple bands of enhanced mid level cyclonic vorticity
pivot counterclockwise around the offshore upper high to
provide some lift.

Precip chances should start to diminish later Mon afternoon into
mon night as the offshore high continues to build westward.

Temperatures will be near seasonable but with very muggy conditions.

A high risk of rip currents will continue on Monday.

Long term Tuesday through Sunday
An unsettled pattern is expected to continue with an omega block in
place, keeping a large scale upper ridge over the southwestern us
and western atlantic, and a large scale upper trough between. As a
result, broad southwest flow will continue to advect moisture into
our region, while both large scale forcing for ascent and a series
of short waves maintain a chance of rain through at least late week.

Although thunderstorms will be possible, the largely tropical air
mass and weak, wet adiabatic lapse rates may act to temper more
widespread coverage. Regardless, periods of heavy rainfall will be
likely, though the timing and placement of these showers will be
uncertain for any given day. There is some indication that a cold
front may approach or even move through by late week, but with
little change in the large scale pattern expect a quick return to
unsettled weather.

Daytime temperatures will remain a few degrees below climatological
normals due to cloud cover and onshore flow, while overnight
temperatures will be above normal. Humidity levels will remain
uncomfortable with dew points in the lower to mid 70s.

Aviation 20z Sunday through Friday
The area remains between the low pressure to the west and high
pressure to the east.

Mainly MVFR ceilings for the remainder of the afternoon.

Isolated showers into this evening as well. Coverage for showers
increases tonight and Monday, so included in forecast (although
it will not rain continuously). Cannot rule out thunder, but
not included in the forecast due to isolated coverage
anticipated.

MVFR ifr conditions expected tonight, with perhaps some
improvement Monday. However, mainly subVFR is expected through
the period.

Se winds persist through the period, with gusts more frequent
for the remainder of the afternoon, and again Monday.

Outlook for 18z Monday through Friday
Monday afternoon-Thursday MVFRVFR with periods of shra and
a chance of tstms. S gusts 20-25 kt during the day.

Friday MVFRVFR in possible showers thunderstorms, with
lighter winds.

Marine
Sca continues for the ocean waters, with 10-ft seas at the
coastal buoys, and the the great south bay where S winds have
been gusting up to 25 kt.

Winds may increase slightly into tonight on the ocean, with
some gusts up to 25 kt as well, and could again approach 25 kt
on the great south bay Mon late morning and afternoon.

Prolonged, steady onshore flow should allow ocean seas to
continue at or above 5 ft into late week. Additionally, a
period of sca-level gusts may be possible on all waters
Wednesday into Thursday as the pressure gradient strengthens
between high pressure to the east, and low pressure to the west.

Hydrology
An unsettled period of weather continues into late week, with
several inches of rainfall possible. The main threat will be
minor urban and poor draining flooding, though isolated flash
flooding may be possible in any heavier showers and
thunderstorms that develop.

Equipment
Nyc NOAA weather radio station kwo-35 (162.55 mhz) remains off
the air for an extended period of time.

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.
