Synopsis for massachusetts and rhode island coastal waters.. Low pressure steering nw towards the great lakes region out ahead of which near gale force S winds will yield increased wave and surf action along with showers and Thunderstorms. Bermuda high builds back into the waters Monday through Thursday resulting in dominant S tropical flow. This prior to a sweeping cold front on Friday.

Synopsis
A potent storm will move up the coast and impact the area,
especially late tonight as the associated low pressure center
passes to the west. A frontal boundary will remain west of the
region through much of the week, with an extended period of
unsettled weather with the chance of showers and thunderstorms
each day.

Near term until 6 am this morning
Latest hrrr brings a strong wind core with gusts 50-60 kt up to
the south shore of nyc and nassau. So a wind advy continues for
western coastal sections for tonight based on that guidance,
along with GFS lamp guidance forecasting advy criteria sustained
winds to 30 kt at bridgeport ct, and close to advy criteria at
kjfk. If latest runs of hrrr are correct there is still a chance
that the advy for the south shore harbor and ocean locations
may have to be upgraded to a high wind warning, especially if
winds take on a more SE vs E component.

Next concern is rainfall. Operational ECMWF hrrr have been
forecasting heavy rain bands capable of producing a quick 2-3
inches of rain either just west of or straddling our NE nj
counties, also additional similar rain bands run through parts
of western long island, the lower hudson valley, and SW ct. Have
higher confidence in the location of the westernmost band but
not those farther east, and since their coverage is not
widespread and href probabilities of 2+ inches of rain was
greatest just west of our area, opted against issuing a flash
flood watch. Depending on where these bands set up, will most
likely have to issue minor flood advisories, but will still have
to watch nyc closely for greater impacts to urban
infrastructure and possible flash flood warnings to address any
direct impact of that magnitude.

As these rain bands ride up into long island and southern ct,
combo of strong 0-1 km shear SRH and sfc-based instability with
sbcape approaching 1000 j kg may be enough to help produce low-
topped tstms capable of producing localized damaging winds or
a brief tornado.

A high rip current risk continues for the ocean waters.

Short term 6 am this morning through 6 pm Monday
By daybreak on Sunday, the heaviest rain should lift mainly
into eastern ct long island. As tropical moisture continues to
stream northward, chances for showers and isolated thunderstorms
increase into the afternoon and at night.

Temperatures will be near normal or a few degrees below average.

A high risk of rip currents is expected for Sunday.

Long term Monday night through Saturday
Unsettled weather expected for the much of the long term period.

An upper level trough and surface front remain nearly stalled west
of the CWA as an atlantic ridge remains offshore.

Periods of showers and thunderstorms will remain likely through at
least the first part of Monday night, especially west of nyc. Pops
then lower on Tuesday and Tuesday night as the upper ridge pushes
back to the west. There does remain some uncertainty with this
feature and kept probabilities across the eastern zones slight
chance and kept chance probabilities to the west of nyc.

An upper level low moving across central canada on Wednesday slides
into the great lakes region by Thursday night. This will push the
trough and front closer to the region, with pops increasing once
again through this period. Its nearly impossible this far out to
time any showers and or thunderstorms and will keep at least some
50% chance pops in the forecast. The trough and front cross the
region during the Thursday night Friday morning timeframe with drier
weather expected for Friday. There may still be some lingering
precipitation, so will continue to maintain some low chance pops.

A tropical like airmass will remain in place next week with highs
each day in the 80s and lows mostly lower to mid 70s. Humidity
levels remain uncomfortable with dew points in the lower to mid 70s.

Aviation 06z Sunday through Thursday
A warm front moves into the terminals late in the overnight and
lifts to the north Sunday. The low with the front will weaken
and track into the eastern great lakes region on Sunday.

Easterly winds and gusts will increase, with sustained speeds
around 20-25 kt, and occasionally as high as 30 kt, with gusts
increasing up to 35 kt and some locally higher gusts at times.

The highest winds and gusts are expected at the coast terminals,
especially kjfk and kisp terminals. Llws will be present for
coastal terminals with a e-se 50-60kt flow at 2kft overnight into
early Sunday morning.

Mainly ifr conditions expected overnight with the rain shower
activity. There will be some locally sub-ifr conditions at
times. Isolated thunderstorms remain in the forecast, with tempo
groups from 06-08z for city terminals and khpn and more in the
07-10z range to the east. MVFR expected on Sunday with showers
becoming less coverage.VFR conditions are even possible
especially Sunday afternoon.

Outlook for 00z Monday through Thursday
Sunday night Mostly MVFR with a chance of ifr in shra and
isolated tstms.

Monday-Thursday MVFRVFR with periods of shra and a chance
of tstms. S gusts 20-25 kt.

Marine
Gale warning remains up for all waters tonight as the coastal
storm works its way up the coast, with sustained winds 25-35 kt
and gusts 35-45 kt expected. There is a chance that winds on the
western ocean waters and new york harbor may be quite a bit
stronger than this, and that this warning may have to be
upgraded to a storm warning. Will be watching coastal obs
along off the DELMARVA and jersey shore for guidance on this
potential.

Gales should subside Sunday morning as a strong southerly llj
shifts east of those waters, with elevated seas continuing.

Winds will remain below SCA levels on the forecast waters
Sunday night through Wednesday. However, with a prolonged
southerly flow and southerly swells, ocean seas will remain at
sca levels through Tuesday. Seas may briefly fall below 5 ft
Tuesday night into Wednesday, but SCA seas then return for
Wednesday night and Thursday.

Hydrology
Rainfall of 1-2 inches is likely in most areas from late tonight
into Sunday morning. Locally higher amounts are possible,
especially in any heavier or more persistent rain bands. Minor
urban and poor drainage flooding looks to be the main threat.

A flash flood threat does exist, but not at high enough
probability to warrant issuance of flash flood watches. This may
change as the coastal storm works its way closer to the area and
radar obs lend confidence on exact location of heavier rain
bands overnight.

A prolonged period of unsettled weather is expected through the
upcoming week, with the chance of showers and thunderstorms
each day. The focus of higher rainfall amounts are expected
along a frontal boundary setting up inland.

Tides coastal flooding
While astronomical tides remain low with the full moon still a
week off, strong e-se winds should result in surge of 2-3 feet,
high enough to yield brief minor coastal flooding in some
locations in around the ny bight, including the south shore of
staten island and the back bays of southern nyc and southern
nassau. The south shore of staten island may be more susceptible
to flooding as strong E winds and shape of the coastline pile up
water in raritan bay. A coastal flood statement has been issued
for the overnight early Sunday morning high tide cycle along the
south shore from nyc to southern nassau county.

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