Area Forecast Discussion
National Weather Service New York NY
723 PM EST Mon Mar 1 2021
.SYNOPSIS...
An Arctic front will pass this evening, producing windy and
cold conditions through Tuesday. High pressure will then
dominate through the week. Low pressure will pass well to the
southeast on Sunday, while high pressure returns on Monday.
&&
.NEAR TERM /THROUGH TUESDAY/...
Per 00Z obs, the Arctic front is just entering NW sections of
the CWA, so stronger winds should hold off until later this
evening after its passage. Stray flurries have already made it
as far SE as NYC, so will continue to mention iso-sct flurries
as well.
The wind advy was still warranted based on the latest progs.
There should be an initial surge of winds with the front tngt,
then perhaps a slight slackening early in the mrng before they
pick up again by 14Z. The NAM in particular keeps 50-55 kt H85
winds in til late aftn. With a deeply mixed atmosphere, the wind
advy was extended a few hours to 4 pm.
Dry wx on Tue with PW around a tenth of an inch.
The NBM was used for low/high temps tngt and Tue, with minor
adjustments. Wind chills tngt will drop into the single digits
for LI and NYC, and will dip blw zero in spots north of there.
Wind chills on Tue will not get out of the teens and lower 20s.
&&
.SHORT TERM /TUESDAY NIGHT/...
A mid lvl wave passes N of the region Tue ngt. Any snow with
this is progged to remain across VT and upstate NY. Dry wx is
expected for the CWA. Winds aloft decrease, and the loss of
diurnal heating will further allow for sfc winds and gusts to
diminish. There could be enough mixing to prevent ideal
radiational cooling. In addition, some mid and high lvl
cloudiness is suggested in the time heights. As a result, the
NBM was used for temps, which more closely resembled the NAM MOS
as opposed to the much colder GFS MOS.
&&
.LONG TERM /WEDNESDAY THROUGH MONDAY/...
A deep closed low aloft will retrograde slowly W across eastern
Canada through the end of the week, while upper ridging persists
from the Rockies into central Canada. Quasi-zonal flow aloft
over the eastern states to start will send sfc low pressure well
to the south on Wed, then become more amplified through Sat,
sending Canadian high pressure with dry and progressively colder
air into the region on a brisk NW flow. Mild temps with highs
from the mid 40s to mid 50s on Wed will only reach the lower/mid
40s on Thu and the 30s on Fri. Weak return flow as a lobe of
the sfc high breaks off and sets up just off the coast should
bring slight moderation for Sat, with highs in the upper 30s and
lower 40s.
The closed low across Canada should begin to weaken beginning
Sat, allowing the ridge to the west to slowly build eastward to
the Plains states, while a Pacific disturbance undercuts the
ridge and enters the base of the longwave trough, with sfc low
pressure developing in the Gulf of Mexico on Sat and then
passing well to the SE on Sunday, though perhaps not as far SE
as model forecasts. Given the dominance of the trough and the
position of the ridge to the west, do not expect this low to
get very close to the coast, and only 1 out of 51 12Z EPS
members showed precip getting to the coast. Allowed a little
extra wiggle room for the low to cut in more closely than the op
and ensemble forecasts as is often the case in this scenario,
but even still that would only warrant slight chance PoP on
Sunday for Long Island and SE CT. At any rate, windy and
continued cold wx expected in the wake of this departing sys on
Mon, with highs only in the 30s.
&&
.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
A cold front moves through the terminals this evening. High
pressure then builds to the west through Tuesday morning and
slides to the south Tuesday afternoon.
VFR conditions through the overnight and on Tuesday.
NW winds 15-20 kt with gusts 30-35 kt through the early evening
increase to 25-30 kt gusting around 40kt. Occasional gusts as high
as 45 kt possible late this evening and overnight. Winds and gusts
begin to diminish Tuesday morning and may be a few kt higher than
currently forecast.
...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...
NW wind gusts may be briefly near 45 kt tonight. Wind gusts Tuesday
morning may be a few kt higher than currently forecast, possibly
near 40 kt especially in the morning.
.OUTLOOK FOR 00Z TUESDAY THROUGH SATURDAY...
.Tuesday night...VFR. Diminishing NW winds 10-15kt after 03Z.
.Wednesday through Saturday...VFR. NW winds gusting 20-30kt possible
Thu.

.MARINE...
Strongest winds and higher seas are holding off til cold fropa
later this evening, still gale warning remains in effect for all
waters. There could be a few isold gusts to storm force,
particularly the ern zones. Some areas of light freezing spray
are possible overnight and Tue as well. Low tides should
approach blowout lvls during the times of low tide Tue mrng.
The guidance indicated lvls would be marginal, so an advy was
not issued attm. The gales diminish Tue ngt, with a SCA likely
needed for most areas for the rest of the ngt, and for the
eastern ocean waters on Wed.
SCA conds likely for most if not all the waters from late day
Thu into Fri night or early Sat morning as NW flow increases
with a reinforcing shot of colder air. Can't totally rule out
gales on the outer ocean waters, but frequent gusts up to 30 kt
appear more likely attm.
