Synopsis
High pressure builds across the area tonight through Wednesday,
followed by the next low pressure system Wednesday into
Thursday. High pressure returns Friday into Saturday before
another low pressure system for Sunday.

Near term through tonight
Very subtle mid level short wave noted in deterministic 700 mb
forecasts and WV imagery is moving through, initiating
sprinkles across parts of the area. The wave should be through
the area by 00z, with all precipitation coming to an end.

Cold advection is already underway, with winds increasing and
temperatures decreasing. With strong cold advection expected to
continue with the building high, expect winds to continue
overnight. Temperatures will be a few degrees below
climatological normals, despite winds keeping low levels fairly
mixed.

Short term Tuesday through Tuesday night
Gusty winds gradually subside into Tuesday with deep layer
ridging building across the area. Temperatures will be
seasonably cold with the modified arctic air mass though,
mainly in the upper 20s to mid 30s.

High pressure is expected to move overhead Tuesday night. With
light winds and clear skies, radiational cooling will be
optimal. Trended on the colder side of guidance, with teens
across the interior and pine barrens of long island, with 20s
closer to the nyc metro.

Long term Wednesday through Monday
An active weather pattern will continue in the long term period with
two systems of concern. The first system is likely to occur late
Wednesday into Thursday and the second for the latter half of the
weekend.

The synoptic pattern for the first storm system is not favorable for
a significant winter storm across the region. The antecedent air
mass is the main ingredient to bring about a concern of front end
wintry precipitation before a wintry mix and then eventually rain.

High pressure gradually shifts from overhead Wednesday morning to
just along the new england coast Wednesday evening. The air will
initially be dry with dew points in the teens. Some concern that the
models are saturating this air mass too quickly due to the proximity
of the high pressure. Another factor of concern is deep layered
ridging aloft. The main shortwave trough and parent low is progged
to be located over the northern plains at 00z Thursday. The main
source of lift will be from warm advection frontogenesis and the
potential of secondary low pressure to develop somewhere along the
middle atlantic Wednesday evening. The 12z NAM appears to be too
aggressive in developing precip early Wednesday afternoon and has
therefore been discounted. Have followed a gfs ECMWF blend for
timing. Another factor to weigh in here is overall model performance
this winter has been subpar regarding similar ptype events, with too
much wintry precip forecast versus actual observations (the most
recent occurring last night into this morning).

This new forecast package shows the potential for snow to develop
for the Wednesday evening commute across the southern half of the
area. Its north and eastward progression will be determined by how
quickly it can overcome lingering dry air and surface and upper
ridging. The snow should overspread the rest of the region after 00z
Thursday. However, due to the unfavorable position of the high and
factors noted above, the snow should quickly transition to a wintry
mix and plain rain at the coast before midnight. This progression
will continue northward through early Thursday morning as warmer
air moves in both at the surface and aloft. Some lingering freezing
rain is possible across the NW interior if surface temperatures take
a bit longer to rise above freezing.

Have followed a conservative approach to snow sleet amounts with
generally 1-2 inches across the region, with lower amounts across
eastern long island and SE ct. A reasonable worst case scenario with
a snowier outcome is for 1-3 inches east and 3-4 inches from nyc on
west. Of note is the 12z ECMWF eps mean probability for greater than
3 inches is generally less than 30 percent. A tenth of an inch or
less of freezing rain is forecast across the interior. Overall
liquid equivalent amounts are around a half inch.

Conditions dry out on Thursday as the main low passes to our north.

A trailing cold front approaches during the day and temperatures
will surge to well above normal levels in the upper 40s to lower
50s. The cold front moves offshore Thursday night. High pressure
and seasonable temperatures return for Friday.

The overall synoptic pattern takes on a similar set up this weekend
with the next shortwave and low pressure amplifying well to our west
with deep layered ridging along the eastern seaboard. There once
again appears to be no favorable surface high to our north. This
makes it much less favorable for all frozen precip and more
favorable for liquid once lift and moisture increases late Saturday
into Sunday. The current suite of models and ensembles has the
highest probability of precip Saturday night into Sunday afternoon.

Temperatures should be near seasonable on Saturday and then possibly
warm above normal on Sunday with current expected track of the low
to our north.

Aviation 20z Monday through Saturday
High pressure builds in tonight.

Nw winds will increase into the evening with gusts developing,
mainly 20-30 kt, with the highest gusts for the city terminals
around 22z. Gusts will gradually subside late tonight.

Conditions are improving toVFR however, could see some bkn030 cigs
until 22z. Otherwise,VFR for the TAF period.
