Synopsis
A high pressure ridge will extend southwest from new england
through Monday night, and weaken on Tuesday. Low pressure moving
northeast across the upper great lakes into ontario and quebec
will send a warm front toward the area Tuesday night, followed
by a cold frontal passage on Wednesday. High pressure will then
settle over the area for late this week, and start to weaken
Saturday night into Sunday.

Near term until 6 am this morning
Overnight is expected to remain dry. Forecast is generally on
track. Cloud coverage was slightly increased and temperatures as
well as dewpoints were slightly adjusted to better match
observed trends.

Short term 6 am this morning through 6 pm Tuesday
The position and strength of high pressure doesn't change much
during this period. Enough lower level moisture remains for partly
to mostly cloudy conditions, but since mid-levels will be drier
there's a better chance for more spots across the tri-state area to
see breaks of sunshine. Low chances for rainfall once again.

This will be mainly during the day and across the coastal
areas. Any rain will will light or in the form of drizzle due to
the dry mid-levels and weak lift. Highs in the 70s and lows in
the 60s.

There is a moderate risk of rip current development at the ocean
beaches on Monday.

Long term Tuesday night through Sunday
With the sfc ridge axis to the north and an approaching mid level
trough, there should be enough low level moisture to make Tue a
mostly cloudy day, with isolated scattered showers. Shower coverage
should increase going into Tue night as the warm front approaches,
with a few heavier showers and tstms possible late Tue night. This
should be quickly followed by cold frontal passage on Wed at least
for nyc metro and points west, but the front could progress slowly
enough to allow for instability to build over eastern ct long island
and spark another round of showers tstms mainly in the late morning
and early afternoon.

At any rate, expect conditions to dry out Wed night, with a stretch
of seasonably warm and comfortably humid days coming up for thu-sat,
with afternoon dewpoints in the 50s, and possibly even dipping into
the 40s in spots on thu.

The high begins to weaken going into Sat night Sunday, and some
showers may be possible during that time frame.

Aviation 06z Monday through Friday
A weak frontal boundary will remain stationary across the mid
atlantic states into Monday, while high pressure noses in from
the north. The high retreat Monday night as a warm front begins
to approach from the south.

Vfr, ceilings becoming MVFR after 09z, from the east to west, at
kgon, kisp, and kbdr. MVFR ceilings may move into the nyc metro
before 13z and indicated this with a tempo with only a chance
of this occurring. Uncertainty with the timing also, and
amendments will be possible before 12z.

Vfr after 12z Monday except MVFR remaining at kbdr, kisp, and
kgon. Here ceilings may briefly improve toVFR in the afternoon
before lowering once again. Amendments will be likely at these
terminals Monday.

An east to northeast flow is forecast through the TAF period
with winds increasing to 10 to 14 kt.

Outlook for 06z Tuesday through Thursday
Mon night MVFR with areas of drizzle and fog. Local ifr.

Tue BecomingVFR in the morning.

Tue night-wed Shower TSTM likely with MVFR conditions.

Thu-fri Vfr.

Marine
Sca remains in effect for the ocean waters through Monday afternoon.

There's a chance that advisory conditions may not be met Monday
morning, but with winds veering E at around 15 kt in the
afternoon, thinking is that if seas fall below 5 ft in the
morning, they could rise back to 5 ft by afternoon.

Additionally, gusts will be close to 25 kt in the afternoon.

Therefore, did not want to shorten the sca, but extended it
through the afternoon instead. It might even need to be extended
into the evening, but didn't have enough confidence to extend
it into another forecast period.

Ocean seas will likely build to SCA levels late Tue night into wed
as SW flow increases to around 20 kt. These elevated seas may linger
out east into Wed night.

Hydrology
No hydrologic impacts are expected through tue.

Showers tstms, some with heavy rain, may be possible Tue night into
wed morning with a passing frontal system. With pw increasing to
well over 2 inches, and deep layer SW flow indicative of potential
training of cells, there is at least potential for urban and poor
drainage flooding issues overnight from nyc north west, which may
linger into the Wed am rush. Flash flood potential is not out of the
question with low FFG values especially over NE nj, but does not
look widespread.

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

Okx watches warnings advisories
Ct... None.

Ny... None.

Nj... None.

Marine... Small craft advisory until 6 pm edt this evening for anz350-
353-355.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
