What forecasters said that day

The local office's own words before this coastal flood statement 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 coastal flood statement went out at Mar 31, 10:29 PM EDT, 2 minutes earlier.

Area forecast discussion, Mar 31, 10:29 PM EDT, 2 minutes before
Area Forecast Discussion
National Weather Service New York NY
1029 PM EDT Fri Mar 31 2017

.SYNOPSIS...
A low pressure system moves south of Long Island tonight and
east of the area Saturday into Saturday night. High pressure
builds to the west late Saturday afternoon through Sunday, and
moves offshore Monday. Another low pressure system will impact
the region Monday night and Tuesday. High pressure returns for
the mid week period, then another storm arrives late in the
week.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
Rain coverage over western zones continues to decrease, with
highest coverage now confined to LI and portions of srn CT.

Low pressure now east of DE. Winds remain gusty and will back to
the N/NE as the night progresses. With this persistent flow,
CWA temperatures were fairly uniform in the upper 30S to lower
40S. Temperatures will remain nearly steady overnight, and
thermal profiles were indicating all rain. After 06Z as the low
approaches south of eastern Long Island winds shift to the north
to northeast and some cold air begins to filter in at the lower
levels and some sleet will be possible inland, and as the
entire column cools snow will be possible toward Saturday
morning. Freezing precipitation is no longer expected. And with
just chances of snow and sleet removed the accumulations from
the forecast. Finally, the best instability will be to the south
and removed the mention of thunder.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH SATURDAY NIGHT/...
The upper low has opened and was tracking a little quicker than
previous thinking. Precipitation will be ending Saturday morning
west and late afternoon into early evening east. Again some
colder air will be wrapping into the low and mixed precipitation
will be possible. Weak ridging and increasing heights after 18s
moves east by 00Z. And may still be too slow to end the
precipitation.

Saturday night will be dry as high pressure builds to the west
and an upper northwest flow continues. Winds will be slow to
diminish and not expected to decouple Saturday night. Saturday
night lows will be fairly uniform, slightly higher in the NYC
metro.

&&

.LONG TERM /SUNDAY THROUGH FRIDAY/...
High pressure builds into the region on Sunday with its ridge axis
passing through Sunday night, then it drifts offshore on Monday. Dry
weather expected Sunday through Monday with the exception of a
chance of light overrunning rainfall moving into the far western
zones Monday afternoon. Went a little above guidance for Sunday's
highs based on mixing to 850mb and moderate downsloping winds. An
onshore flow and increasing clouds are then expected to hold highs 3
to 5 degrees below normal on Monday.

Models still agree that low pressure approaches from the west Monday
night with its center passing over or just south of us late Tuesday
into Tuesday night. An associated warm front is progged to remain to
our south, however a surface trough extends from the low center into
the CWA. This could be a focus for moisture convergence and a region
of possible heavy rainfall as a theta-e ridge and potentially a 50-
60kt jet at 850mb shift through during the day on Tuesday. Have gone
with PoPs increasing to likely across the area Monday night and have
kept them at likely through Tuesday before tapering off Tuesday
night.

High pressure builds back in for Wednesday with a return to dry
weather and near-normal high temperatures.

Models are coming into better agreement with the timing of a late-
week system that could impact the region. So far it's shaping up to
be a primary low moving through the Great Lakes Region with a triple
point or secondary low developing and moving in the vicinity of the
forecast area. Will cap PoPs at chance for now with the best overall
chances of rain being Thursday night into Friday.

&&

.AVIATION /03Z SATURDAY THROUGH WEDNESDAY/...
Low pressure moves south of the area tonight.

Rain becomes more intermittent and generally lighter overnight,
although moderate rain is possible from time to time. Ceilings
and visibilities should hover around IFR/MVFR, with possible
LIFR conditions late.

Slow improvement is expected Saturday, with a return to VFR possible
during the afternoon hours, less likely though eastern terminals.

Gusty easterly winds will back to the northeast overnight, then
north toward morning. Gusts may become less frequent for a time
overnight, but increase in frequency again Saturday, after
13-15z.

.OUTLOOK FOR 00Z SUNDAY THROUGH WEDNESDAY...
.Saturday Night-Monday...VFR.
.Monday night-Tuesday night...Sub-VFR possible in rain.
.Wednesday...Return to VFR.

.MARINE...
Low pressure tracks through the ocean waters overnight, and
then to the east Saturday and Saturday night. As the low deepens
overnight and tracks south of Long Island, winds and gusts will
be increasing. Gales all waters except NY Harbor. Gale force
gusts continue on the ocean through Saturday. NY Harbor looks
to be a little less with SCA conditions expected there and gusts
closer to 30 kt. This small craft advisory is in effect until
Saturday evening.

As the low moves east Saturday night winds are expected to
quickly diminish and fall below small craft Saturday evening.
However ocean sea will likely run high into Sunday morning.

Winds diminish on Sunday, however seas on the ocean are
expected to be up to 5 ft at least during the morning hours.
All waters will then be below advisory criteria by Sunday
night. A ridge of high pressure will then shift through the
waters during the night, then and onshore flow develops on the
backside of the high on Monday, but still weak enough to
maintain sub- SCA conds on all waters. A coastal storm is then
forecast to pass over or just south of the waters during
Tuesday afternoon/night. SCA conds expected on all waters
during this time. Gales are not out of the question either as a
low level jet of 50-60kt potentially passes through, but
confidence of gales is not high enough even for a mention in
the HWO at this time. The storm departs for Wednesday, however
a lingering swell could keep ocean seas above 5 ft through the
day.

&&

.HYDROLOGY...
An additional 1 inch is possible, mainly eastern locales.
Western portions of the CWA should observe improvement as the
bulk of the widespread heavier rain has ended.

Any rain that coincides with the time of high tide will
exacerbate roadway flooding in low-lying coastal communities.

Additional rainfall of an inch to two inches is likely Monday night
through Tuesday evening. This may result in at least minor
hydrologic impacts.

&&

.TIDES/COASTAL FLOODING...
An approaching low pressure system is expected to bring
widespread minor coastal flood impacts to vulnerable coastal
communities along lower NY/NJ harbor, southern bays of LI/NYC,
and western LI Sound during tonight's high tide cycle. This high
tide cycle starts late tonight. Locally moderate flooding is
possible along the southern bays of western LI. It is possible
gauges farther away from the larger bodies of water such as the
NY Harbor coastlines and the Peconic Bay could just touch minor
coastal flooding benchmarks during high tide late tonight.

Tidal departures of 1 to 1 1/2 ft are needed to reach minor
flood levels and 2 to 2 1/2 ft for moderate flood levels during
this time.

An onshore flow with a storm passing just to the south of the
forecast area has the potential to cause some minor coastal flooding
primarily over the south shore back bays of western Long Island for
the early morning and late day high tide cycles on Tuesday.
Confidence in flooding occurrence is not high due to uncertainty of
the storm track, strength, and timing in addition to astronomical
tides being relatively on the lower side as the first quarter moon
phase occurs on Monday.
