Area Forecast Discussion
National Weather Service New York NY
1220 AM EST Thu Mar 2 2017
.SYNOPSIS...
Deepening low pressure tracks along the Canadian and New England
border and into the Canadian maritimes through Thursday with an
associated cold front moving through the tri state region
tonight. High pressure builds to the west Thursday night. A
weak Alberta Clipper low will pass to the south on Friday,
followed by strong high pressure building from the west this
weekend. The high will pass east Monday into Tuesday while a
series of warm fronts pass to the north. A cold front will pass
through Tuesday night, followed by high pressure on Wednesday.
&&
.NEAR TERM /UNTIL 6 AM THIS MORNING/...
The approaching cold front is expected to move through southeast
NY and northern NJ around 06Z, then slowly move east through the
remainder of the forecast area, departing eastern CT and Long
Island around 08-09Z. There remains a slight chance of showers
along the front despite an overall downward trend of intensity
and coverage. Although there's an occasional gust noted around
05Z, current obs show the strongest gusts generally lagging an
hour or two behind the front. Expect stronger winds to develop
across the area between 08-11Z. Strong cold advection,
subsidence and a lingering low-level jet will allow stronger
winds to mix to the surface today, with potential for gusts of
40 to 50 MPH. Wind advisory conditions are on track for today.
&&
.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM FRIDAY/...
The higher winds will be moving to the east Thursday afternoon
and cold advection weakens somewhat. Gusts are expected to
diminish late Thursday afternoon and into the evening, with
gusts below advisory levels. So ending the advisory at 22Z still
seems reasonable.
After 06Z Friday winds and gusts diminish as deep layer ridge
builds toward the area. Winds decouple and skies will be nearly
clear. With a cold airmass in place temperatures will drop
quickly late Thursday night, and may be near to below normal
levels.
&&
.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
Friday: Global models were better initialized with respect to the
upstream mid level energy associated with the Alberta Clipper that
will pass just south on Friday. The 12Z NAM was initialized too far
north and carries a good deal of its forcing too far north into
Friday, while the 15Z SREF mean was in between the global models and
the NAM. With these ideas in mind have gone with GFS/ECMWF/SREF
blend for Friday, with chance PoP and a most likely scenario of a
coating to an inch of accumulation, more so for NYC/Long Island and
points south. Higher PWPF percentiles suggest potential for 1-2
inches of accumulation, so this will still have to be watched. At
any rate the Friday morning and evening commutes should be spared
direct impacts. High temps look to be in the mid/upper 30s, perhaps
reaching 40 after snow ends Fri afternoon and before strong cold
advection kicks in.
The clipper will reinforce the cold air already in place, with lows
falling to the teens and 20s Fri/Sat night, and highs only 30-35 on
Sat.
A moderating trend will take place thereafter, though perhaps not
quite as fast as global models originally suggested, with highs
reaching 40-45 on Sunday and 50-55 on Sunday. With a couple of warm
fronts passing to the NW during this time, should see plenty of mid
level clouds if not low clouds NW of NYC.
Temps should warm up once again to well above avg on Tue ahead of an
approaching cold front, with highs at least in the 50s, and possibly
lower 60s with enough sunshine per 00Z ECMWF. After cold fropa late
Tue night temps will cool somewhat, but still remain above average,
with highs either side of 50.
&&
.AVIATION /05Z THURSDAY THROUGH MONDAY/...
VFR through the TAF period. A cold front moves across the terminals
early this morning with deepening low pressure tracking into the
Canadian Maritimes through today.
SW winds to begin the TAF period will veer to the W behind the front
and then WNW after sunrise. Speeds will increase through the early
morning hours with gusts 30-35 kt, especially after 09z. Gusts may
be a bit weaker away from the city terminals. A peak gust around 40
kt cannot be ruled from about 09z through day break.
Winds continue to increase during the day. Sustained speeds 20 to 25
kt expected with gusts ranging from 35-40 kt into the early
afternoon. Sustained speeds and gusts will gradually weaken late in
the afternoon and evening. Wind direction may be near or just left
of 310 magnetic through the day.
.OUTLOOK FOR 06Z FRIDAY THROUGH MONDAY...
.Thursday Night...VFR. WNW winds diminishing.
.Friday...MVFR/IFR possible with a chance of light snow. NW winds
G20-25KT.
.Saturday...VFR. NW G20-25KT.
.Sunday...VFR. Chance of rain. SW winds G20KT.
.Monday...VFR.
&&
.MARINE...
Deepening low pressure tracking along the Canadian and New
England border will bring a cold front across the forecast
waters from late this evening into late tonight, and likely be
east of the waters by 08-09Z.
Persistent southwesterly flow has allowed seas to build higher
than previously forecast, so have adjusted the forecast to
reflect these trends. Observations show winds have been gusting
anywhere from 35-39 kt across the ocean waters in advance of the
front, so have replaced the Small Craft Advisory with a Gale
Warning. Gale conditions still anticipated on the sound for
today.
Strong cold air advection behind the cold front and low level
winds at 700 to 850 MB to around 50 KT will mix down to the
water surface and gale gusts are likely Thursday into late
Thursday afternoon. A gale warning remains in effect for
Thursday. As both cold advection and low level winds weaken late
Thursday afternoon winds quickly subside with a brief period of
small craft gusts possible, then winds and seas will be below
small craft later Thursday evening and Thursday night.
After an Alberta clipper low passes to the southeast on Friday, NW
flow should increase to gale force on the ocean and to SCA levels
elsewhere, and last into Sat night.
As high pressure builds in on Sunday, SCA conds to start should
diminish from W-E through the day, with quite conds on all water
from Sunday night through Tue.
