What forecasters said that day

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

NWS Buffalo, NY wrote its last area forecast discussion before this flash flood watch went out at Apr 4, 11:03 AM EDT, 20 minutes earlier.

Area forecast discussion, Apr 4, 11:03 AM EDT, 20 minutes before
Area Forecast Discussion
National Weather Service Buffalo NY
1103 AM EDT Wed Apr 4 2018

.SYNOPSIS...
Behind a cold front damaging winds will continue through the
afternoon hours, diminishing this evening. Weak surface high
pressure will then begin to build into the region tonight. Residual
snow showers will slowly diminish south and southeast of the lakes
tonight with fair and dry weather Thursday. A weak clipper system
will cross the Eastern Great Lakes Thursday night with some light
snow expected through Friday.

&&

.NEAR TERM /THROUGH TONIGHT/...
This late morning a deepening area of low pressure is now to the
north of Lake Ontario, with a cold front roughly just to the east of
I-81 and then southward. Winds have increased to warning criteria
this morning across much of WNY, and as cold air and stronger winds
aloft continue to build eastward expect damaging winds to increase
across the Finger Lakes and East of Lake Ontario.

Rain will end with the exit of the cold front across the North
Country around noontime. As the upper level low approaches scattered
rain rain/snow showers through the day will transition to all snow
by this evening.

...STRONG DAMAGING WINDS...

As the aforementioned low tracks north of Lake Ontario this
afternoon, strong isallobaric rises will occur. This coupled with
impressive lapse rates, ongoing cold air advection and daytime
mixing will allow for winds aloft (55 to 65 knots) to effectively
mix down to the surface. Winds areawide, especially during the
daytime will easily mix down to the surface with wind gusts of 55 to
60 mph. The strongest winds will likely be found along the lake
plains as winds will funnel up lake Erie with sustained winds of 35-
40 mph, with gusts near 65-70 mph. Expect winds to peak in the
afternoon and then diminish in early evening hours.

The other area of concern will be Lake Shore Flooding, a lakeshore
Flood Warning is in effect for Wayne, Northern Cayuga, Oswego and
Jefferson county on lake Ontario for high lake levels. Additionally,
strong winds funneling up lake Erie will likely lead to water rises
with lake waters peaking between 7-8 feet above low water datum. Of
additional concern is the remaining lake ice on lake Erie. With
strong winds the remain ice could be pushed inland onshore leading
to shoreline erosion, with southwest winds the ice may even be
pushed over the ice boom and into the Upper Niagara River resulting
in damage along the Upper Niagara River shoreline.

Temperatures will fall through the 30s today with strong cold air
advection behind the cold front.

Tonight, lake snows will slowly diminish overnight and winds will
subside into Thursday as surface high pressure builds into Western
and North Central New York. Lows overnight will drop into the 20s
areawide with teens inland across the higher terrain of the Western
Southern Tier and east of lake Ontario.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
On Thursday a weak bubble of high pressure and drier air will
build across our region from the Ohio Valley. In tandem with
strong early April diurnal influences...this will bring an end to
lingering scattered lake effect snow showers east and southeast
of the lakes...with only minor additional accumulations expected
from these. Otherwise it will be a much quieter but also cold
day...with afternoon highs mostly in the lower to mid 30s...or
some 15 degrees below normal.

The dry weather will then persist into Thursday evening...before
quickly giving way to a potent channelled shortwave and an attendant
developing clipper low rapidly diving southeastward from central
Canada/the Northern Plains states into the Great Lakes Region. This
system will bring a widespread general light snowfall to most areas
between later Thursday night and Friday morning...with this then
quickly diminishing from west to east Friday afternoon. Depending
upon the exact track of this system...a factor which still remains
in question given the continued fluctuations seen in most guidance...
enough warmer air could be drawn northward into our region during
the day Friday to allow the snow to end as a light/rain snow mix...
and there could also be another period of generally windy conditions
as well - though nothing like what will be seen from today's much
stronger system. In terms of snowfall accumulations...most areas
should see a general 1 to 3 inches of snow from the clipper...with
the bulk of these confined to the overnight hours of Thursday night...
and then to just the higher terrain and/or elevated/grassy surfaces
on Friday...when strong diurnal influences and increasingly marginal
surface temperatures will help to greatly limit accumulation potential.

In the wake of this system...some scattered lake and orographically-
driven snow showers will then linger across areas east and southeast
of the lakes Friday night with some minor additional accumulations
possible...otherwise conditions will be mainly dry with temperatures
falling back into the lower to mid 20s again as progressively colder
air once again overspreads our region in the wake of the clipper.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
As we move into this weekend...high pressure and colder/drier air will
gradually build eastward across the Great Lakes. With a lingering westerly
to west-northwesterly low level flow in place...some weak/scattered lake
effect snow showers will remain possible east and southeast of the lakes...
though with the fairly dry and only marginally cold enough environment
these will likely be mostly confined to the nighttime and early morning
hours...with diurnal influences tending to disrupt these the remainder
of the time. Otherwise...it will just be quiet and mainly dry with
temperatures remaining significantly below normal through the weekend.

Looking ahead to early next week...another upper level trough and
attendant low pressure system should approach and then cross our
region in the Monday-Tuesday time frame...though this being said the
medium range guidance suite remains all over the map with respect to
both its track and timing. With this in mind...have just broadbrushed
some mid-range chance PoPs and general rain/snow chances both days for
the time being...with the diurnal cycle the primary dictating factor
for ptype.

&&

.AVIATION /15Z WEDNESDAY THROUGH SUNDAY/...
Widespread rain, with IFR flight conditions, is exiting the
KART airfield this late morning...with just scattered
precipitation expected the remainder of the day. Otherwise
behind a cold front strong southwest to west winds will gust to
50-55 knots across the region. These winds will begin to subside
this evening.

Behind the front, flight conditions will be mainly MVFR today,
with lower conditions possible across higher terrain east of the
lakes due to snow showers.

Outlook...

Thursday...VFR, except local MVFR/IFR in lake effect snow showers
southeast of the lakes.
Friday...MVFR with a chance of rain and snow
showers.
Saturday...VFR, except local IFR in lake effect snow
showers southeast of the lakes.
Sunday...mainly VFR.
Monday...MVFR/VFR with a chance rain and snow.

&&

.MARINE...
Behind a sharp cold front winds will quickly ramp up to gale
force on the Lakes and Rivers. Additionally, Storm Warnings
have been issued for eastern lake Erie and the eastern open
waters of lake Ontario. Expect the strongest winds through the
afternoon hours before diminish as the storm system pulling
farther away to the east this evening and tonight.

Another strong low will pass just north of our region Friday, and
may bring another round of gales to the eastern Great Lakes.

&&

.TIDES/COASTAL FLOODING...
Deepening low pressure tracking just to the northwest of the
area today will bring a period of strong westerly winds to Lake
Ontario, which will result in an elevated risk of lake shore
flooding and erosion along the Lake Ontario shoreline from Wayne
to Jefferson counties. For this reason, a Lakeshore Flood
Warning has been issued for these areas.

On Lake Erie...a seiche/period of elevated lake levels will also
occur, with a lake shore flood warning now in effect. One
unusual concern is that with ice on the lake the seiche may push
this onshore which may cause damage to some shoreline locations.
