What forecasters said that day

The local office's own words before this storm warning 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 storm warning went out at Apr 4, 3:19 AM EDT, 55 minutes earlier.

Area forecast discussion, Apr 4, 3:19 AM EDT, 55 minutes before
Area Forecast Discussion
National Weather Service Buffalo NY
319 AM EDT Wed Apr 4 2018

.SYNOPSIS...
A cold front will cross the region as low pressure tracks past the
Lower Great Lakes bringing with it strong winds and colder
temperatures with rain changing to snow showers on Wednesday.
Weak surface high pressure will then build into the region
Wednesday night. Residiual snow showers will diminsh south and
southeast of the lakes Thursday with fair and dry weather. A
weak clipper system will cross the Eastern Great Lakes Thursday
night with some light snow expected through Friday.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Low pressure across western Lake Erie will track across
southern Ontario province through Wednesday. This will result in
rain, strong winds, and even some thunderstorms.

Late this evening, there was mainly scattered showers across
the area, with fairly limited areal coverage. Radar shows
steadier rain just to the west, with some thunderstorms embedded
in this. This will continue to move to the east, spreading into
western New York overnight. There will continue to be some
thunderstorms, which will mainly be due to elevated instability
shown by best LI's or MUCAPE in model guidance.

High Winds...We will expand the high wind warning to now include all
counties. Strong isallobaric rises behind the cold front of 6 to 7
mb/3 hrs...coupled with strong lapse rates, cold air advection and
daytime mixing to the base of a 55 to 65 knot LLJ will generate
damaging westerly winds across the region. Strongest winds will
be across the flat lake plain where winds blowing off Lake Erie
could reach sustained speeds of 35 to 40 mph, with gusts near
65 mph. In addition winds will gust near 65 mph through the SLV
which will lie closest to the isallobaric couplet around the
surface low. Winds across the higher terrain will also reach
damaging speeds, with the daytime mixing easily transporting
gusts 55 to 60 mph down to the ridge tops. Expect damaging gusts
to peak in the afternoon...diminish late afternoon and early
evening with the setting of the sun/lowering mixing heights and
the surface low pressure pulling farther to the east and
relaxing the pressure gradient.

Lake Shore Flooding...Have expanded the lakeshore flood warning to
now include Lake Erie. A strong easterly wind today and this evening
will push lake waters westward...to be pushed back eastward tomorrow
morning on a strong southwest to westerly flow. Lake Erie waters
will likely peak over 8 feet above low water datum. The remaining
Lake Erie ice should pose no problems to rising water heights...and
in fact may become a problem along the lakeshore line and Niagara
River. The remaining ice may bring erosion along the Lake Erie
shoreline, with the southwest winds possibly pushing ice over the
ice boom and into the Upper Niagara River resulting in damage along
the Upper Niagara River shoreline. A lake shore flood warning
remains for the eastern waters of Lake Ontario owing to high lake
levels.

Temperatures tonight will rise through the evening and early
morning...into the upper 40s to mid 50s. A sharp cold front will
quickly return these temperatures into the 30s tomorrow.
Consensus 850mb temperatures are forecast to fall below
-10C Wednesday afternoon, supporting mainly snow showers despite the
 April calender date. This may result in some light snow
 accumulation across the ridges east of Lake Ontario and Erie
 through early Wednesday evening.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY/...
The strong winds are expected to gradually diminish from west to
east Wednesday night as wind fields aloft weaken, and we lose the
mixing effects of daytime heating. A wedge of colder air will
continue to deepen Wednesday night within a west northwest flow,
bringing a brief transition back to a lake effect regime. Snow
showers east-southeast of the lakes will bring some minor
accumulations.

High pressure sliding across the Ohio Valley Thursday will provide a
quieter weather day with only some lingering lake effect snow
showers east of the lakes, gradually falling apart due to strong
early April diurnal influences.

A potent shortwave will drop out of central Canada and become
absorbed into a more zonal flow pattern over the Northern Plains
Thursday night. This will quickly carry the wave into the Upper
Great Lakes and to the lower Great Lakes by Friday morning, with a
surface low quickly deepening as it is carried into southern
Ontario. This system will bring the likelihood of some light snow to
all areas later Thursday night and Friday, though the bulk of any
accumulations from this will likely remain 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 rather marginal surface temperatures will greatly limit
accumulation potential.

Temperatures through the period will average much below normal with
daytime highs averaging in the 30s and nighttime lows mainly in the
20s.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
A longwave trough persists across the Great Lakes region Saturday
and Sunday. Northwest flow behind an exiting clipper system will
bring below normal temperatures and the chance for lake effect snow
showers through the weekend. High pressure will approach the eastern
Great Lakes Saturday and Sunday and subsidence and lack of synoptic
moisture will limit any significant development of lake effect bands
Saturday-Sunday. High temperatures will reach the mid to upper 30s
for the weekend and no impact to snow accumulation is expected.

High pressure will move overhead Sunday night into Monday and any
lingering snow showers will taper off. A brief relief to the below
normal temperatures is expected Monday as winds become southerly
ahead of the next area of low pressure. Model guidance is depicting
a potent shortwave trough to drop south into the Mid-West Monday
morning while deepening low pressure moves into the Ohio Valley.
Warm air advection will likely bring rain or snow to the region
Monday night-Tuesday.

&&

.AVIATION /07Z WEDNESDAY THROUGH SUNDAY/...
Regional radars show a large area of mainly light/moderate rain
moving across the forecast area. This is produceing mainly MVFR/VFR
CIGS with a few locations in the heavier precipitation briefly
producing IFR CIGS/VSBYS. Otherwise, as low pressure over London
Ontario Canada slowly track northeast past the Lower Great Lakes it
will send its cold front across the region with surface winds
picking up in intensity following the frontal passage early
Wednesday morning. Gusts to 45 knots are expected across the lake
plains during the day Wednesday.

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

Outlook...

Wednesday night and Thursday...VFR, except local 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.

&&

.MARINE...
A strong cold front will cross the Eastern Great Lakes early
Wednesday morning. Winds will quickly increase behind the front to
gale force on the Lakes, and the Upper Niagara River and Saint
Lawrence River. A small craft will be in place for the Lower Niagara
River. Strongest winds through the afternoon and evening will begin
to diminish with the storm system pulling farther away to the east.

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 on Wednesday 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.
