Synopsis
Low pressure moves well southeast of the area tonight. A weak
cold front slowly approaches from the west through Tuesday then
moves through late Wednesday afternoon into the evening hours.

High pressure then briefly builds back for Thursday. A couple of
cold fronts follow for Friday night and Saturday.

Near term until 6 am Tuesday morning
Early update because of marine changes. Otherwise, the fcst was
on track with no major changes made. The earlier vorticity
maximums ahead of a broad upper low have moved offshore, ending
steadier rain across the area. Subsidence aloft observed on wv
imagery should act to maintain if not strengthen the low level
inversion. Given the continued onshore flow trapping moisture
beneath the inversion, periods of drizzle and patchy fog will
likely persist through the night. Cloud cover and onshore flow
will moderate temperatures overnight keeping values close to
climatological normals.

Short term 6 am Tuesday morning through Tuesday night
Fog and drizzle will likely continue through the morning,
particularly closer to the coast as onshore flow persists
beneath a low-level inversion. Although the low-level cloud deck
may lift some, clearing appears unlikely and as such any
instability ahead of the approaching system will remain
elevated. Shower chances will increase through the day from west
to east ahead of a convectively enhanced vorticity maximum. Any
thunderstorm chance will be greatest to the north and west of
the city, but thereafter the marine influence may gradually
decrease ongoing activity leading to mainly showers overnight.

At the moment instability appears weak, but if a stronger cell
can develop to the north and west of the city, given
strengthening deep-layer wind shear, small hail will be
possible. Onshore flow leads to lowering clouds and the
development of occasional drizzle and patchy fog once again,
outside of any steadier rain associated with the aforementioned
vorticity maximum. Similar to Monday, high temperatures will be
below normal while lows will be closer to climatological
normals.

There is a moderate risk of rip currents at atlantic facing
beaches on Tuesday.

Long term Wednesday through Monday
A cold front approaches on Wednesday and is forecast to move through
the area late in the day to early evening hours. Lift ahead of the
front, plus upward motion from a shortwave and possibly a coupled
jet structure aloft are expected to produce scattered showers during
this period. Capes are forecast to be high enough for some
thunderstorms, some of which could produce strong gusts with 0-6km
shear around 50 kt. High temperatures near normal.

Zonal flow aloft and weak surface ridging should keep us dry on
Thursday along with high temperatures once again near normal.

The timing of the next cold front is still uncertain as a closed
500mb low drifts across southern quebec Friday into Saturday. Looks
like the main cold front would pass through sometime on Saturday
with a weak front or pre-frontal trough shifting through the
region Friday evening. Will go with isolated to scattered showers
and thunderstorms from Friday afternoon through Saturday for now.

Some uncertainty in the weather pattern continues into Sunday and
Monday, owing to differences among the models regarding the
magnitude of upper and surface ridging to our west behind the
departing upper low over the canadian maritimes. Prefer the
drier more ridging solution of gfs, so will go with dry conditions
on Sunday. Then with an upper trough axis moving closer on Monday,
isolated showers and thunderstorms with the cold pool aloft.

Aviation 03z Tuesday through Saturday
Weak high pressure over the area will slowly give way to a
frontal system approaching from the west the next couple of
days.

This will keep the area under an easterly flow with low clouds,
fog, and a chance of light rain or drizzle.

Widespread MVFR conditions lower to ifr overnight, and then
gradually improve after daybreak. There is some uncertainty
though with ceilings and visibilities overnight as some of the
guidance indicates several hours ofVFR conditions as the low-
level ridge strengthens over the area with drier air working in
at the low levels. Confidence in this scenario is increasing,
but mainly for the terminals east of nyc.

Mainly MVFR on Wednesday with a chance of an afternoon shower
or thunderstorm from nyc metro nw.

E SE winds overnight at 5 kt or less, then ramping up to 7-12
kt Tuesday afternoon.

Outlook for 00z Wednesday through Saturday
Tuesday night Low clouds with ifr conditions. Chance of
showers, possibly a thunderstorm.

Wednesday and Wednesday night Ifr to start, improving toVFR
by afternoon. Chance of showers and possibly a thunderstorm in
the afternoon evening hours.

Thursday Vfr.

Friday and Saturday Chance of showers and thunderstorms with
MVFR or lower conds.

Marine
The SCA was converted to a SCA for seas, and extended thru the
overnight with waves running about 5-6 ft, a ft abv wavewatch.

A relaxed pressure gradient over the region from Tuesday into
Friday morning should keep winds over the local waters below
advisory criteria. The pressure gradient then tightens, and
combined wind waves and swell could build seas to 5 ft on the
ocean by late in the day Friday, which could then linger through
Saturday. Non-ocean waters should remain below SCA criteria
during this period.

Hydrology
No significant widespread hydrologic impacts are expected
through the week.

Tides coastal flooding
Water levels may approach minor coastal flood benchmarks with
the high tide cycle tonight, mainly for the southern bays of
nassau nyc.

Okx watches warnings advisories
Ct... None.

Ny... None.

Nj... None.

Marine... Small craft advisory for hazardous seas until 6 am edt Tuesday
