Area Forecast Discussion
National Weather Service New York NY
639 AM EST Mon Dec 25 2017
.SYNOPSIS...
Low pressure deepens rapidly off the New England coast, then
tracks into the Canadian Maritimes today. Arctic high pressure
builds into the region tonight and for the mid to late week
period. A storm system will be possible for the end of the week
into the weekend.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Heavier band moving through, with back edge noted. A changeover
to snow has occurred across western half of the CWA, with
eastern LI and SE CT still warm enough for rain.
Band of heavier snow will quickly produce an inch or two of snow
accums, but will be brief.
By late morning, any lingering wintry precip departs to the
northeast, with partly sunny skies expected this afternoon.
Once this low/inverted trough passes, expect an abrupt wind
shift to the west, and a sharp increase in speeds. Wind
advisories remain in effect for the entire area, and gusts 45 to
55 mph are expected by mid to late morning into the afternoon.
Temps should remain nearly steady from early morning readings,
with highs in the mid to upper 30s, to near 40 near the coast.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM TUESDAY/...
Dry but cold weather will prevail as the storm pulls away and
cold high pressure builds to the west. Gusty winds begin to
diminish tonight, but winds still remain gusty tonight and
Tuesday as the pressure gradient remains fairly tight.
This will add to the chill with lows in the teens and 20s
tonight, and highs only in the upper 20s to around 30 Tuesday
under partly cloudy skies.
&&
.LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...
Models continue in good agreement with a deep polar trough over
the CONUS through the period, but still with subtle differences
in how exactly the polar low over Hudson's Bay and associated
heart of arctic airmass shifts/expands east for mid to late
week. This model spread increases for the weekend.
Main story for mid week into the weekend will be the frigid
temps as pieces of the polar upper low near Hudson's Bay
extend/break off eastward through Ontario and Quebec and arctic
high pressure builds southeastward from the central Canada.
This will begin an extended period (Wed thru Fri) of daytime
highs not getting much above the lower to mid 20s, and overnight
lows in the teens and single digits. These frigid conditions
may continue right through the weekend into early next week.
Cold of this duration and magnitude will incrementally increase
the potential for frozen/burst pipes, space heating related
mishaps and other cold weather impacts through the week.
Finally in terms of precip, will have to watch interaction
between polar jet and PAC energy for Tue Night/Wed time period
as a few model members still signaling potential for a quick
moving low brushing the region. Thereafter, models continue to
signal potential for a late week/weekend winter storm, but as
would be expected at this time frame there is quite a bit of run
to run and model to model inconsistency in the details.
Ultimately, this storm evolution will depend on the nature of
polar low energy swinging towards the NE/Mid Atlantic, and its
interaction with PAC jet energy.
&&
.AVIATION /12Z MONDAY THROUGH FRIDAY/...
Low pressure intensifies as it moves up the coast today,
creating windy conditions in its wake. Early this morning, a
rain/snow mix will quickly pass to the east, with conditions
improving to VFR by around 14-16Z.
Thereafter, WNW winds will quickly strengthen into the
afternoon, with sustained speeds around 20-30 kt and G35-45 kt,
strongest near the coast. Gusty winds continue into tonight,
with speeds gradually decreasing.

.MARINE...
SCA-level seas will quickly build today as winds rapidly strengthen
behind a frontal passage. Expect gale-force winds on all waters, and
storm-force east of Moriches Inlet across the ocean waters,
with the strongest winds expected through the early afternoon.
Overall, gusts in the 40 to 50 kt range will prevail, with the
potential of gusts to around 55 kt over the far eastern ocean
waters. Winds then begin to diminish as the storm pulls further
away tonight. Gales may continue at least across the eastern
waters into tonight, depending on the timing of the low.
Winds will remain strong into Tuesday, albeit weaker than the
previous day, with at least SCA conditions continuing on the waters.
Winds and seas then gradually diminish into Tuesday night as high
pressure builds across the area.
Winds may briefly strengthen into mid week depending on the
development of a coastal low that will pass to the east. Otherwise,
the next chance for SCA conditions may be by late week as low
pressure deepens up the coast.
