Area Forecast Discussion
National Weather Service New York NY
1233 PM EST Thu Jan 16 2020
.SYNOPSIS...
Deepening low pressure system exits to the northeast allowing
for very gusty northerly winds locally through the evening.
Strong surface high then builds into northern New York state
later Thursday through Friday night. A complex frontal system
will impact the area Saturday and Saturday night. High pressure
will again build in early next week and settle over the area by
mid week.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Heights are falling and instability is increasing across the
forecast area. Upstream radar has significant coverage of rain
and snow showers. Isolated rain and snow showers have therefore
been included for the remainder of the day. Intensity is
uncertain, as low topped convection could encounter too much
shear. However, at least some 1/2sm snow is possible, especially
across the nwrn areas, as evidenced by obs at Monticello. With
the cold front now through the area, temperatures should now
fall through the day despite the deep mixing.
Otherwise, the main concern in the near term today will be the
northerly wind gusts up to 50 mph with sustained 20-30 mph. A
wind advisory is in effect for the entire forecast area from 9am
until 10pm this evening. Soundings near the city show a
boundary layer up to 800 mb with winds around 40-45kts. These
gusty winds have the potential to mix down to the surface owing
to relatively clear skies and diurnal heating.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/...
A few isolated rain or snow showers are not out of the
questions behind the front late in the afternoon towards the
early evening hour. Dry cold air with dew points in the single
digits rapidly pushes south into the forecast area by the late
evening. Temperatures overnight are expected to drop into the
low 20s. This cold air regime continues into the day. A +1040mb
over the Great Lakes high builds into the northern portion of
New York state throughout Friday. Brisk north wind though much
lighter than the previous day will aid in keeping ambient
temperatures right around freezing. One important note is that
the wind chill Friday could be in the teens for most of the
island, Lower Hudson Valley and Southern Connecticut.
&&
.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
Strong high pressure builds across the region into Friday night
with cold temperatures expected. Lows Friday night will be
mainly in the teens in outlying areas, to around 20 degrees in
towards the city.
High moves offshore Saturday as a low pressure system moves
towards the area from the Great Lakes. There are quite a few
details to note with this pending storm system. Due to the
progressive nature of the pattern along with the lack of a
negative AO and NAO, the models are not indicating a decent CAD
scenario. With the lack of cold air damming and with the low
system tracking to the west and north, a strong southerly flow
will be developing ahead of the low, and while cold air will
initially be in place, this is expected to change to rain in
most, if not the entire area. The main takeaway here with the
polar jet going right over the region by Saturday evening and
the 500 mb vorticity maximum going slightly north of the region,
the chance of an all snow scenario for much of the area is
unlikely. The biggest question is how quick can the deeper
moisture arrive and mix with the colder air before it can exit,
especially in the lower levels. With the onset of precipitation
and for the first few hours it precipitates temperatures should
hold nearly steady. Due to the fact that the departing high
pressure system is rather strong and there will be cold air in
place initially, precipitation is expected to begin as all snow
Saturday late morning into the early afternoon. The timing of
the main mandatory level features suggest precip / snow start
time on Saturday to be centered at or just before 18z as the 500
mb ridge passage takes place just before then, and the leading
edge of the 700 mb moisture starts to move over the region. It
will develop from west to east and with at least a few hours of
snow, then transitioning quickly to rain/snow, especially closer
to the coast, then all rain, from south to north by late
Saturday afternoon and through the evening. Across northern
sections the snow will take longer to transition to rain, and
across parts of Orange County the transition completely to all
rain may not occur. Therefore there is the possibility of
advisory level snowfall across these areas. Then by late
afternoon and evening temperatures should climb rather quickly,
especially for southern and eastern portions of the area. The
thinking is that highs on Saturday will be low to mid 30s inland
and upper 30s to around 40 elsewhere.
This system will be fast moving, and precipitation will be
ending overnight Saturday likely by 3-5z Sunday as the mid
levels dry out quickly. Only a few lingering flurries are
expected across the higher inland terrain as the low departs
Sunday. The main story then becomes the wind, as once again
there will be the potential for gusty winds into the day on
Sunday as the departing low deepens over the NW Atlantic. The
winds will then gradually come down into Monday with building
high pressure.
The long wave pattern basically undergoes a transition across
the CONUS by early next week. The global guidance is suggesting
a mean eastern US trough and western US ridge long wave pattern
until further notice. Canadian high pressure builds toward the
region behind the departing low and a prolonged period of below
normal temperatures is expected.
&&
.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
Strong arctic high pressure builds in from the west through
Friday morning as a deepening low pressure tracks well
offshore. The high settles over the terminals by Friday
evening.
Mainly VFR. A few flurries or snow showers cannot be ruled out
across the Lower Hudson Valley this afternoon. A brief shower
or sprinkle is possible this afternoon elsewhere.
Strong NW winds NW, 20 to 25 kt, gusting 35 to 40 kt through the
afternoon. NW winds will be around 310 true this afternoon and
early evening. The wind direction will trend to the right of 310
magnetic tonight. Gusts weaken a bit, but still should be 30-35
kt overnight. NW winds weaken further through Friday.

.OUTLOOK FOR 18Z FRIDAY THROUGH TUESDAY...
.Friday Afternoon...VFR. NW gusts 20-25kt, diminishing late
afternoon and evening..
.Saturday...IFR or lower with snow developing late
morning/afternoon. Snow changes to rain southeast to northwest
late afternoon into the evening, likely remaining snow well
northwest. 1-2 inches possible NYC/LI, 2-4 inches possible for
CT and Lower Hudson Valley Terminals.
.Sunday...VFR. W/NW G25-35kt.
.Monday-Tuesday...VFR.
&&
.MARINE...
Gale warning remains in effect for all waters. Strong south winds
rapidly transition to W-NW gales behind a surface boundary Thursday
morning. Winds gusts 40-45kts with seas 6-8 feet will be possible
over the ocean waters by the late afternoon. The Long Island
Sound could see gusts up to 40 mph with 4 ft waves.
Gale force gusts are expected to continue across all the waters
through mid morning Friday. For now the Gale Warning lasts until
Friday afternoon. SCA conditions should persist through the
remainder of the day with northwest winds relaxing along with seas
by the evening.
There will then be a brief period of below advisory conditions
before winds and seas increase late in the day Saturday, and
into Saturday night and Sunday as low pressure moving to the
north impacts the local waters. Gales will be likely on the
ocean waters, especially further east late Saturday night into
the first half of Sunday, with small craft conditions more
likely for the remainder of the waters. Conditions should
improve late Sunday through Monday, slowly falling below SCA
Monday afternoon into Monday night for the majority of the
coastal waters for the middle of the week as high pressure
builds across the area waters. Perhaps the eastern ocean waters
will maintain marginal SCA seas and wind gusts Monday night into
Tuesday with high pressure continuing to gradually build in
from the west.
