Synopsis
As high pressure continues out to sea today, a warm front will
lift through the area, followed by a cold front Monday evening.

High pressure will return for the middle of next week. A frontal
system may affect the region Friday night into Saturday.

Near term through tonight
Upper level ridge axis will shift to the east today with sfc
high pres continuing to depart further into the atlantic.

Meanwhile, WAA also continues with a warm front approaching from
the south, which should lift north of the area this aftn. Hrrr
and rap have been signaling some isolated shower development
between 6am and noon or so for the last several model cycles,
which is likely associated with the warm fropa, so have added in
low chance pops during this time for much of the tri-state area.

Would expect them to weaken as they encounter more subsidence
as they move east.

Otherwise, after mostly cloudy skies this morning associated
with the warm front, should see a fairly decent amount of
sunshine under partly cloudy skies. Humidity levels will start
to increase as well. A southerly flow and cloud cover lingering
a bit longer to the east will keep highs at the coast ranging
from mid 60s to lower 70s while further inland mid 70s to lower
80s will be common.

A trough of low pres will develop across central pa va this
aftn with moderate instability and wind shear profiles
suggesting the potential for organization of scattered strong
to severe convection into a qlcs type structure. Indications are
that this activity would not reach areas well NW of nyc until
early evening (5-6pm, possibly a few hours later). There will be
a quick drop off in surface instability east of the hudson
river, as well as waning diurnal instability overall in the
evening. So, there is potential for a convective line, with main
threat of strong to locally damaging wind gusts, to approach
areas west of the hudson in the early evening, but expectation
would be for this convection to transition to elevated as it
approaches the coast. Cant rule out isolated strong wind gusts
making it into the nyc nj metro and ct lower hud border sun
evening, but intensity of storms should continue to diminish
into the evening as the stable layer deepens.

This feature along with some weak mid level energy will
likely be enough to trigger TSTM development with moderate
instability present and bulk shear increasing during the aftn.

While there is limited forcing locally, some of these storms may
make it into western portions of the forecast area late this
afternoon into the early evening as the sfc trough slides east.

A few could be strong with gusty winds being the main threat.

However the maritime airmass will quickly weaken the storms as
they move east into nyc LI and southern ct.

Showers and embedded elevated tstms will likely continue
through at least the first half of the overnight with the trough
sliding through accompanied by weak mid level vorts and a
40-50kt llj. Otherwise, a very mild and relatively humid night.

Potential for advection stratus fog across coastal areas tonight
with high dewpoint airmass overriding lower to mid 50 degree
waters. Lows around 60 coast, and mid 60s nyc nj metro and n&w.

Short term Monday through Monday night
Closed low developing over southern quebec on Monday will
gradually move east sending a cold front towards the area.

Despite the potential for moderate instability shear profiles
away from the coast, most of the shortwave energy will pass to
the north of the area and will probably arrive too late in the
day for widespread severe weather. Height falls aren't very
impressive until eve and the upper jet is lagging as well. The
amount of cloud cover from a potential fog stratus bank is
another limiting factor, especially across eastern areas.

Thus, while there could be some storms with the cold fropa, do
not anticipate much in the way of severe weather late mon
aftn eve. A drier airmass returns in the wake of the front mon
night.

Humidity levels will be more noticeable on Monday and while
there is bust potential on forecast temps (due to cloud cover)
think we should break out for a bit almost everywhere which will
allow temps to rise into the lower to mid 80s in nyc and areas
n and W and upper 60s to mid 70s closer to the coast, coolest
east where clouds will likely hang on longer.

Long term Tuesday through Saturday
High pressure builds in for Tuesday and into the middle of the
week. Dry weather conditions are expected with temperatures near
normal. Thursday through Saturday low rain chances are expected
as weak weather impulses impact the region with a thunderstorm
possible each afternoon. Temperatures will rise above normal
seasonal levels by the end of the week and into the weekend.

Aviation 08z Sunday through Thursday
The weather pattern features an approaching warm front today
which is forecast to move across late today into tonight.

MainlyVFR conditions are forecast through the TAF period but with
increasing chances of MVFR ifr late tonight. While not in the tafs,
isolated showers will be a possibility going into today with some
possible brief MVFR. There will be a round of rain showers that will
be greater coverage mainly during tonight. There will be a chance of
thunderstorms mainly during the early evening, highest to the north
and west of nyc terminals with just a slight chance of thunderstorms
to the east of nyc terminals.

Winds will be se-s 5-10 kts initially, then increasing to 10-15
kt this afternoon before slightly decreasing tonight. Expecting
gusts to develop late this morning and continue through the
early evening around 20 kt on average. Some llws will be
possible east of city terminals tonight with SW flow of around
40 kt at 2kft.

Outlook for 06z Monday through Thursday
Late tonight through Monday MVFR ifr possible at times,
with a chance of showers tstms. Patchy fog late tonight into
early Monday. S-sw gusts near 20 kt mainly during the day Monday.

Monday night-Tuesday A chance of MVFR ifr in showers and
thunderstorms east of nyc terminals Monday evening. Otherwise,
becomingVFR. Gusts subside Monday night. NW gusts near 25-30 kt
Tuesday. Gusts subside Tuesday night.

Wednesday MVFR possible. A slight chance of showers Wednesday
night.

Thursday MVFR possible. A slight chance of showers and
thunderstorms.

Marine
Conditions mainly below SCA today but could have wind gusts approach
25 kt on the ocean and some nearshore waters. Felt frequency of 25
kt would just be occasional so left SCA to when the ocean seas would
be reaching 5 ft for tonight. Conditions mainly on the ocean will be
meeting minimal SCA thresholds tonight with wind gusts mainly 15-20
kt. SCA issued for tonight into Monday with SCA on the ocean
(earlier start time of 22z west of moriches inlet and later start
time of 02z east of moriches inlet) with a continued southerly fetch
that will increase on Monday again as southerly winds increase to 15-
20 kt with gusts up to around 25 kt. This will keep elevated seas on
the ocean. The SCA ends at 22z Monday but may need to get extended
with subsequent forecasts.

Winds subside Monday night but the higher seas on the ocean will
probably remain, meeting minimal SCA criteria. For non-ocean waters,
conditions forecast to remain below SCA tonight through Monday
night. Ocean seas subside more on Tuesday with a NW flow picking up
to around 15 kt with gusts 25-30 kt, making for potential SCA across
all the local waters for this timeframe.

Conditions are forecast to be mainly below SCA late Tuesday
night through Thursday.

Hydrology
Widespread hydrologic impacts are not expected through next
Friday.

Tides coastal flooding
Tides continue to run astronomically high due to a full moon.

There is a low probability for localized minor coastal flooding
for western portions of the south shore bays of long island and
southwest ct shorelines during Sunday evenings high tides.

Equipment
Nyc NOAA weather radio station kwo35 (162.55 mhz) remains off
the air.

Okx watches warnings advisories
Ct... None.

Ny... None.

Nj... None.

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.
