What forecasters said that day

The local office's own words before this gale warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS New York, NY wrote its last area forecast discussion before this gale warning went out at Nov 29, 12:47 AM EST, 2 hours 25 minutes earlier.

Area forecast discussion, Nov 29, 12:47 AM EST, 2 hours 25 minutes before
Area Forecast Discussion
National Weather Service New York NY
1247 AM EST Sun Nov 29 2020

.SYNOPSIS...
High pressure slides south of the area through Sunday.
Deepening low pressure brings unsettled weather Monday into
Tuesday. The low lifts up into southeast Canada on Wednesday
with high pressure returning for the end of the week. Another
strong low pressure may impact the area next Saturday.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
The forecast is mostly on track with minor edits made to some of
the hourly weather elements.

High pressure builds in from the southwest. A clear sky and
relaxing wind will provide for a fairly decent radiational
cooling night, especially in areas where the wind can become
calm for any period of time. This will more likely occur away
from the coastline.

Lows tonight will be generally in the 30s with lowest values to
the north and northwest and warmest temperatures around the NYC
metro where temps may not get out of the low 40s. Any spots
where the wind can become calm can drop into the upper 20s.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM MONDAY/...
High pressure slides to our south through the day providing for
clear skies and dry conditions with light W to SE winds. High
temperatures will be slightly above average by about 5 degrees,
generally in the middle 50s.

By Sunday night, high pressure shifts offshore allowing for the
winds to become more southerly. This will begin to advect
moisture into the region overnight as skies become progressively
cloudier ahead of an approaching low pressure. Some scattered
showers may develop after Midnight and before 6 AM Monday ahead
of the primary area of precipitation associated with the
deepening low. Lows on Sunday night will be slightly above
average, generally in the low to middle 40s with come areas to
the north dropping into the upper 30s.

&&

.LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
A deepening low pressure tracking from the Middle Atlantic into
Upstate NY will bring impactful weather to the region Monday into
Monday night. There is also growing potential that unsettled
conditions continue across the region on Tuesday as a secondary low
develops near or just west of the region.

The greatest impacts are likely to occur Monday into Monday evening.
The models continue to come into better agreement, although there is
still many variables that forecaster confidence remains low. Large
scale forcing along with a subtropical moisture feed will bring
overspread rain across the region from SW to NE Monday morning. The
rain will become moderate to heavy Monday afternoon into early
Monday evening. Overrunning rain ahead of the systems warm front is
likely in the afternoon. As the triple point nears, the
precipitation may become more convective. Have added slight chance
of thunder as soundings are indicating enough elevated instability
that a few lightning strikes cannot be ruled out. The middle level
dry slot is then progged to quickly overspread from west to east,
possibly starting as early as sundown across western zones, then
spreading east during the remainder of the evening. This has been
consistently shown on all model guidance, just the timing has
fluctuated a bit. Even with a few hours timing difference, the most
widespread rain should taper off from west to east in the evening,
with the most significant coverage in the evening across eastern
Long Island and southeast Connecticut. The deep moisture plume and
large scale forcing shifts well offshore Monday night. Forecast
rainfall amounts range from 1.5 to 2 inches, with locally higher
amounts possible. Minor flooding is the main threat with this
rainfall.

Strong, possibly damaging winds are still possible Monday afternoon
and evening. However, forecast confidence in seeing winds exceeding
high wind criteria is low at this time. A strong low level jet is
still progged by the NAM with winds 65-75 kt between 925 mb and 850
mb. The core of these winds mainly moves over Long Island and
southeast Connecticut. The GFS has also come into a bit better
agreement with the LLJ. The strongest surface winds still look to
occur over Long Island and southeast Connecticut. The latest
thinking is for sustained winds 25 to 30 mph with gusts 45 to 55 mph
over these areas Monday afternoon and early evening. Winds will be
weaker across the northwest interior being further from the low
level jet and warmest air. In the NYC metro, sustained winds 20-25
mph with gusts 30 to 40 mph are forecast. Any deeper convection may
be able to bring some higher winds down to the surface, but it
should be noted there is an inversion indicated in model soundings
below the strongest low level winds. This inversion could prevent
these higher winds from mixing down. A wind advisory will likely be
needed for Long Island and southeast Connecticut in subsequent
forecasts. The timing of the strongest winds looks to be about 19z
to about 22z as the low level jet quickly shifts to our east. Winds
Monday night into Tuesday morning look much lower except for the
Forks and far southeast Connecticut where gusts up to 35 mph may be
possible into early Tuesday morning due to a stronger pressure
gradient.

The low is associated with a southern stream wave that lifts north
ahead of a deepening northern stream shortwave that eventually
becomes an anomalous longwave upper trough. The northern stream
shortwave is now becoming better sampled by the RAOB network in
North America. The trends in the models have slowed its timing a
bit, with amplification occurring Monday night. Potent vorticity
maxima are progged to round the base of the trough with height falls
occurring over the area by Tuesday morning. A stronger jet streak
develops across the southeast coast Tuesday morning, with the
northeast in the region of stronger divergence aloft and in the left
exit of the jet. A secondary low may develop near or over the area
Tuesday morning and then eventually get captured by the longwave
trough Tuesday night. Several members of the GEFS and the CMC now
show this scenario, with the ECMWF beginning to trend this way. What
this means in terms of sensible weather is still a bit uncertain due
to the deepest moisture plume getting pushed east Monday night. The
height falls and cold pocket aloft along with the secondary low
should be enough to develop showers on Tuesday. The main uncertainty
is with coverage and have held PoPs at chance for now. If the system
can pull back some deeper moisture, then coverage of precipitation
will be more widespread especially for eastern parts of the area.
Breezy conditions will likely continue regardless, especially in the
afternoon and evening Tuesday as the low lifts northward.

The system becomes vertically stacked Tuesday night into Wednesday
and lifts into southeast Canada. Colder and breezy conditions are
indicated for Wednesday as the region remains under cyclonic flow
aloft. High pressure builds for the end of the week. However, the
synoptic pattern remains highly anomalous and amplified. Models
continue to show potential for another low pressure to develop
across the southeast at the end of the week, possibly deepening
rapidly as it lifts across the northeast next Saturday. Confidence
is low at this time, but will continue to monitor model trends over
the coming days.

&&

.AVIATION /06Z SUNDAY THROUGH THURSDAY/...

.MARINE...
Sub SCA conditions through Sunday as high pressure overhead
allows for clear conditions and light W/SW winds.

A gale watch has been issued for all waters Monday through the
first half of Monday night. Winds increase Monday morning and
should reach gale force on all waters. There is a low chance of
a storm force gust, mainly on the ocean waters. However, a low
level inversion will likely prevent any of the significantly
higher winds aloft from mixing down. Will not mention the storm
force gust potential in the HWO at this time due to it being a
very low probability. Seas on the ocean build Monday morning,
becoming 10 to 14 ft by Monday night. Seas on central and
eastern Long Island Sound could also build to 3 to 5 ft in the
afternoon and evening. Winds will weaken from west to east
Monday night, and could even fall below SCA levels briefly. SCA
winds then return on Tuesday on all waters and may remain on the
ocean on Wednesday and Thursday. Ocean seas will remain high
Tuesday into Wednesday, subsiding close to 5 ft on Thursday.

.HYDROLOGY...
1.5 to 2 inches of rainfall is forecast Monday into Monday night.
Locally higher amounts cannot be ruled out. The heaviest rain is
likely to occur Monday afternoon and early evening. This rain may
produce minor urban flooding where the heaviest rain occurs.

Showers are possible on Tuesday with no hydrologic impacts expected
at this time.

&&

.TIDES/COASTAL FLOODING...
Minor to locally moderate beach erosion along with overwash appears
likely along the oceanfront Monday afternoon through Tuesday.

Tide levels on Monday will respond quickly to strong onshore flow
and freshwater input due to heavy rain. Fortunately, the highest
surge is still forecast to occur either mid cycle or during the
lower of the two daily high tides (evening high tide). Isolated
minor coastal flooding impacts are expected with the high tides
Monday evening along south facing coastlines of NY Harbor, the south
shore of western Long Island, and western Long Island Sound.

Continued onshore flow into Tuesday could present a more widespread
minor flood threat with the Tuesday morning high tide cycle due to
tidal piling.
