.DISCUSSION...
.KEY MESSAGE 1...
One last round of Cold Weather Advisories is in effect for
Orange and Putnam Counties tonight into Monday morning where
wind chills tonight may drop to -10 to -15 degrees.

Persistent cold conditions will continue through this week with
temperatures remaining well below average, generally by 5-10
degrees. Temperatures increase slightly through this week with
highs each day remaining generally in the middle to upper 20s
inland and low 30s near the coast. While there may be a few days
where temperatures hit 32 or 33 along the coast, largely the
entire area should generally remain below freezing through the
week.

Lows each night will be generally in the teens along the coast
through the week and single digits to low teens for the inland
areas. Despite the persistent cold, wind chill values should
remain high enough to not warrant any cold weather headlines
through at least Friday.

.KEY MESSAGE 2...
A cold front is forecast to move across the forecast area late
Friday into Saturday. This front is expected to bring a chance of
light snow or snow showers, along with a re-enforcing shot of cold
air. High temperatures over the weekend will only reach the teens
and lower 20s, with lows overnight in the single digits. A few
locations may even see temperatures fall below 0. Winds are expected
to increase behind this front. With gusty winds and the colder
temperatures, can not rule out cold weather headlines for the
weekend.

.KEY MESSAGE 3...
Astronomical levels are still high with recent full moon. Surge
forecast to increase tonight into early Monday but NW flow will
be a negative offset to this, with total water levels near the
same levels as experienced today as a result.

Total water levels observed with earlier high tide cycle were
less than forecast. With NW gusty flow continuing through much
of tonight and redeveloping Monday, thinking here that surge
forecasts will end up being on the lower side with primary
offshore flow.

The only places that reached minor coastal flood benchmarks were
a few sites in the South Shore Bays and these areas are in
coastal flood statement for Monday morning. This includes
Southern Queens and Southern Nassau.

Isolated minor coastal impacts are expected Monday morning
within the South Shore Bays but will be less probable for other
shorelines with water levels forecast to fall short of minor
coastal flood benchmarks.

.AVIATION /03Z MONDAY THROUGH FRIDAY/...
Strong low pressure well offshore continues to track northeast
into the Northern Atlantic through Monday as high pressure
gradually builds in from the west.

VFR.

A NNW flow continues through the forecast period. Gusts 18-24 kt
remain at the terminals into late tonight, ending 06Z/07Z, with
the exception of KSWF where gusts are not expected. There is a
chance that occasional gusts continue an hour or 2 later than
forecast. Gusts to around 20 kt develop 14Z/15Z Monday, and may
be more occasional before ending Monday afternoon.


 NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...

Occasional gusts could continue an hour or 2 longer than
forecast tonight.

Gusts start and end time could be 1-2 hours off from TAF, and
gusts may be more occasional.


.OUTLOOK FOR 00Z TUESDAY THROUGH FRIDAY...

Monday night-Thursday: VFR.

Friday: MVFR or lower with a chance of snow.

.MARINE...
Northerly winds slowly diminish tonight. A Gale Warning remains
in effect for the ocean waters into the first half of tonight.
For the non-ocean waters a SCA has replaced the Gale Warning
that had expired, and continues through tonight, and possibly
into a part of Monday morning. Advisory conditions remain on the
ocean late tonight through at least some of Monday night, and a
SCA will be needed once the Gale Warning expires.

A weak pressure gradient will result in relatively tranquil
conditions through the mid-week period. Low pressure is expected
to pass south of the waters on Wednesday, however conditions
right now are forecast to remain below SCA conditions. Another
chance for SCA conditions come late in the week or next weekend
with the passage of a cold front.
