.WHAT HAS CHANGED...
There have been no changes to headlines.

.KEY MESSAGES...
1) Blizzard conditions gradually winding down into this evening.
2) A passing warm front will bring some light snow and rain on
Wednesday. A stronger low passing close by will bring additional
wintry precip Thursday into Thursday night.

.DISCUSSION...
.KEY MESSAGE 1...
The intense coastal low that has brought several feet of
snowfall to portions of the area today continues to pull
northeast this afternoon and into tonight. Given the tight
pressure gradient remaining in place, strong winds may continue
to result in Blizzard conditions through early this evening,
mainly from the potential of blowing snow reducing visibilities
to less than one quarter of a mile.
Widespread snowfall is generally weakening over the area with a
few residual snowbands bringing a more moderate to locally heavy
snowfall over the next several hours. Generally an inch or less
of additional snowfall is expected but upwards of 2-3
additional inches will remain locally possible under any more
persistent snowband.
As the system winds down, the wind will also continually taper
through the evening and overnight. Gusts of 35-50 mph remain
possible, especially along the coast through this evening. Winds
weaken substantially by midnight so that gusts will be closer to
20-35 mph. Wind continues to decrease into Tuesday morning.
.KEY MESSAGE 2...
As a clipper low passes to the north on Wednesday, an associated
warm front should bring some light snow and rain on Wed. Accumulations
should be on the light side, ranging from less than an inch
across Long Island, to around an inch in NYC and along the CT
coastline, to 1-2 inches north/west of there.
A stronger low moving from the OH valley to the lower Great Lakes on
Thu could bring more wintry precip. NBM thermal profiles were mainly
supportive of snow and/or rain. Any snow amts should be light,
no more than an inch or two of snow most places and a light
glaze of ice inland NW of NYC. Either way advisories could be
needed for parts of the interior north/west of I-287 in NJ/NY
and along the I-84 corridor in CT.
High temperatures Tuesday range from the upper 20s to lower 30s,
then trend closer to normal the rest of the week. This will allow
for gradual snow melt each day, and with mostly sub-freezing
temperatures at night into early morning, subsequent re-freeze of
snow melt.
&&
.AVIATION /18Z MONDAY THROUGH SATURDAY/...
Deepening low pressure continues to lift to the northeast
through the TAF period.
Conditions are starting to improve as snow bands across the
area continue to dissipate. There still continue to be some
snow bands that could produce a brief period of 1/4sm through
the next hour or two. Otherwise, expect to the snow to end from
west to east this afternoon and evening. Improvements to MVFR
likely by afternoon.
In addition, with the gusty winds across the region, expect
areas of blowing snow through the day today.
NE winds 25-35 kt with gusts 35-40 kt expected early this
afternoon, then winds will gradually diminish through the
evening and overnight.
...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...
Amendment is possible for changing flight categories this
afternoon.
.OUTLOOK FOR 18Z MONDAY THROUGH FRIDAY...
Tuesday: VFR. NW winds gust 20-25kt.
Tuesday Night-Wednesday: MVFR possible with chance of light
snow Tuesday night, then rain/snow mix Wednesday.
Thursday: MVFR or lower. Rain/snow mix possible near coast with
snow possible inland.
Friday: Mainly VFR.

.MARINE...
A major winter storm continues to impact the waters through this
evening.
A Storm Warning remains in effect for all waters except the NY
Harbor and Western LIS where a Gale Warning is in effect.
Strong winds with gusts of 35-50 kt will continue to gradually
dissipate this evening and overnight. Seas of 10-15 feet will
fairly quickly diminish overnight so that by Tuesday morning,
ocean seas should be 5-7 feet.
As Storm Warning conditions drop this evening, additional
headlines will need to be issued as conditions step down.
SCA conditions linger into Tue morning on the ern Sound and
Peconic/Gardiners bays, with NW flow still gusting up to 25 kt, and
on the ocean for gusts up to 30 kt for seas 6-8 ft. Some 5-6 ft seas
should linger on the ocean into early Tue evening.
An extended period of SCA cond then likely on the ocean from Wed
into Fri as a series of frontal systems pass through, mainly for
hazardous seas. SW flow 20-25 kt expected on the ocean with warm
frontal approaches daytime Wed and again Thu night.
