.WHAT HAS CHANGED...
Probabilities for snow Sunday into early Monday have increased.

.KEY MESSAGES...
1.) Confidence increasing in a winter storm Sunday into Monday.

2.) A prolonged period of below freezing temperatures is expected
beginning Friday night and continuing through the middle of next
week.

.DISCUSSION...
.KEY MESSAGE 1...
Continued good agreement among the deterministic and AI models
regarding a winter storm impacting the area Sunday into Monday.
Longwave pattern continues the trend of greater phasing between
northern and southern stream energy, helping to steer low
pressure closer to us compared to the depictions of 24+ hours
ago. 12z Weds suite consensus would have a low pressure center
passing near or just south of the 40N/70W benchmark Sunday
night. An inverted trough connected to a weaker low center to
our northwest may then shift through on Monday, which could
result in higher chances of lingering snow than currently in the
forecast for Monday.

It`s still too early for any specifics on amounts as changes in
the upper pattern and resulting storm track will impact
amounts, and with the potential start time of the event still 4
days away, there`s still plenty of time for trends to be
continued or disrupted. Changes in the potential liquid
equivalent amounts, warm air intrusion from a closer storm
approach, and the placement of a potential coupled jet structure
and other sources of enhanced lift, are among factors will
influence snowfall amounts. Something which at least is more
certain are cold temperatures (teens to mid 20s) through the
event, and this is something that would contribute to higher
snow to liquid equivalent ratios. The latest NBM probability for
greater than 6 inches of snow has now increased to 80-90
percent across the entire forecast area. The potential exists
for the snow to be drier and powdery based on the arctic air
mass in place, but these details will be worked out as the event
draws closer.

The bottom line here is that an impactful winter storm is
increasingly likely Sunday into Monday. The storm track, timing,
and snow amount details will be in better focus over the next
few days.


.KEY MESSAGE 2...
Return flow around an offshore area of high pressure will help
lift a weak warm front through the area tonight. This will allow
temperatures to remain nearly steady or slowly rise overnight
before peaking in the low to mid 40s Thursday afternoon. The
warm frontal passage may be enough to spark a few rain or snow
showers late this afternoon into tonight. Any precipitation will
be light, with any snowfall accumulations limited to a few
tenths of an inch.

The brief reprieve from the cold ends quickly as a cold front
crosses the area Thursday evening. This front will usher in a
colder airmass for Friday, with highs only rising to around 30
inland and just a few degrees above freezing near the coast.

A reinforcing shot of cold air arrives Friday night as another
cold front crosses the area. Under cold air advection,
temperatures Friday night will drop into the lower single digits
across typically cooler locations to around 10 across the New
York City metro. These temperatures combined with 10-15 mph
winds will result in wind chills ranging from 0 to -10, which
may eventually warrant cold weather headlines.

After near advisory-level wind chills early Saturday morning,
the afternoon remains in a frigid airmass. Records for the
lowest maximum temperature could be tied or broken for some of
the local climate sites on Saturday. See the climate section
below for the current records. High temperatures each day from
Sunday through Wednesday are expected to be mainly in the 20s
with lows in teens to single digits. Wind chills could approach
advisory thresholds Monday night into Tuesday morning.

.AVIATION /03Z THURSDAY THROUGH MONDAY/...
A cold front approaches tonight. A cold front moves through
Thursday evening.

Mainly VFR through the TAF period. A stray snow and/or rain
shower is possible, mainly for KHPN, KBDR, and KGON.

SW winds 5-10 kt this evening for most terminals. KJFK will see
5-15 kt, with gusts 20-25 kt through around 04Z expected at
coastal terminals this afternoon and evening. Other coastal
terminals such as KBDR, KGON, and KISP may see sustained winds
near 15 kt or gusts 20-25 kt through 02Z, when gusts end or
become more occasional. However, there is a chance that gusts
continue for these locations through the night. SW winds
continue early Thursday morning and increase to around 10-15kt
with gusts around 25-30 kt.

LLWS is more likely now and has been added to the TAFs. Winds at
2 kft are expected to be 40 to 50 kt out of the SW. This will
occur through 07-09Z.

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

LLWS is more likely now and has been added to the TAFs through
07-09Z. If any precipitation does occur, it will likely be
light enough to not cause vsby impacts.

.OUTLOOK FOR 00Z FRIDAY THROUGH MONDAY...

Thursday night: VFR. W winds 5-10 kt, gusts diminishing through
the night.

Friday: VFR. W winds becoming NW gusts 20-25 kt in the
afternoon.

Saturday: VFR.

Saturday night into Monday: Snow becoming likely with IFR and
N-NE G20kt. Snow ending late Monday.

.MARINE...
Winds will increase through the afternoon, with gusts to 25kt
expected on the ocean waters, the Great South Bay, and the
eastern Long Island Sound by late afternoon. A Small Craft
Advisory remains in effect for these areas. Elsewhere, winds
will remain sub SCA-criteria, with gusts to around 20 kt
expected.

SCA conditions will continue on the ocean waters through the
day on Thursday, and may expand over the non-ocean waters for a
period late Thursday morning into Thursday afternoon. Winds
should then briefly subside on all waters early Friday morning
before increasing again Friday afternoon in association with a
cold frontal passage.

Relatively tranquil conditions are expected Saturday through
Saturday night with seas subsiding on a weakening NW to N flow.
Low pressure then brings a chance of gales across most, if not
all, waters for at least Sunday into Sunday night and possibly
lingering into Monday.
