What forecasters said that day

The local office's own words before this small craft advisory 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 small craft advisory went out at Apr 18, 9:27 AM EDT, 4 hours 51 minutes earlier.

Area forecast discussion, Apr 18, 9:27 AM EDT, 4 hours 51 minutes before
Area Forecast Discussion
National Weather Service Buffalo NY
927 AM EDT Wed Apr 18 2018

.SYNOPSIS...
A large upper-level trough will pinwheel across New England while
keeping a supply of cool air in place across the region through
Friday. Meanwhile a western wave will track from the Rockies to just
south of the Great Lakes while merging with the upper-level trough
tonight and Friday. Expect widespread light snow with minor
accumulations mainly over higher terrain. High pressure will build
across the region this weekend into early next week finally brining
drier weather and moderating temperatures.

&&

.NEAR TERM /THROUGH TONIGHT/...
A broad upper-level low pinwheeling across New England is
keeping a parade of shortwave troughs training across the
forecast area along with below average temperatures. This
morning, a shortwave trough can be seen in WV imagery moving
south across NYS, while generating a loosely organized area of
snow east of Lake Ontario. KTYX radar shows locally enhanced
returns over the Tug Hill, as the moist northwesterly flow
upslopes. Given this, the winter weather advisory in place for
the Tug Hill looks on track. Expect general accumulations of 3
to 5 inches over the higher terrain with locally up to 6 inches
possible, with this accumulation mainly coming through mid-day
with snow tapering off this afternoon. Lower elevations around
the Tug Hill will likely see much less snow accumulation, only
around an inch or two.

Behind this shortwave passage, snow will taper off today from west to
east, with snow ending east of Lake Ontario by this afternoon as a
subtle ridge axis crosses the forecast area. The mainly dry
afternoon with westerly winds in place will allow temperatures to
range from the low 40s downwind of the lakes, to the mid 40s in the
Genesee Valley and Northern Finger Lakes regions.

Tonight, a wave ejecting from the Rockies will track toward the
eastern Great Lakes while merging with the large upper-level low
over New England. The wave will phase just south of the forecast
area while the surface reflection tracks across PA. The result will
be a system largely cold enough to support snow, although a mix of
rain at precipitation onset cannot be ruled out. Enough warm air
aloft may reach near the PA state line in the far Southern Tier for
a brief wintry mix, however as the wave continues eastward the
column will cool enough to support all snow there as well. The
highest snowfall rates will be found across the Southern Tier near
this transition line, with a quarter to a half inch per hour briefly
possible tonight. Meanwhile snowfall will be much lighter for areas
just south of Lake Ontario, with only a tenth or two per hour
likely. The overall result will be an inch or less of accumulation
across the lake plains tonight, with 1 to 2 inches of snow expected
across the higher terrain of the Southern Tier east to the Finger
Lakes. Expect impacts and snowfall amounts to remain below winter
weather advisory criteria.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
Latest models continuing to trend toward a solution which tracks a
wave of low pressure just to the south of New York state to the
southern New England coast Thursday. The track of the low will keep
western New York on the cold side with nearly all the precipitation
falling as snow, at least during the morning hours, before diurnal
warming of the boundary layer allows for some rain to mix in. Most
of the accumulating snow will be during the morning with
temperatures near freezing. Could see additional accumulations of 1
to 3 inches across the higher terrain, but in general, a half to one
inch should cover the majority of western and north central New
York.

Lingering upper level trough and a cold cyclonic northwesterly flow
will help to produce additional snow showers Thursday night with
minor additional accumulations of an inch or two.

Chances for precipitation will lessen from west to east Friday into
Friday night as the axis of the upper level trough shifts east and
high pressure and drier air build into the region.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
Sprawling surface ridge over the Central Great Lakes will slowly
meander eastward and then overhead into early next week. Cool
conditions will persist with northerly cyclonic flow continuing on
the backside of the mid-level trough which will maintain below
normal high temperatures both Saturday and Sunday. A weak short wave
(Alberta Clipper)is forecast to drop southeast across Quebec Canada
and then into the Lower Great lakes late Saturday into Sunday. This
feature will help to maintain the mid-level trough and the cool but
dry northerly flow across the region through the weekend. Sunday
night, behind the passage of the latest short wave building 500mb
heights and the surface ridge moving overhead a significant warming
trend will initiate across the region Monday and then into Tuesday.

Expect a slow but gradual recovery of high temperatures over the
weekend. Saturday will be the coolest day of the period with highs
in the 40s. Sunday, expect L50s which for April is still below climo
(M/U 50s). Monday, highs will finally climb above normal with
temperatures expected in the U50s to near 60F and then L60s
everywhere Tuesday.

&&

.AVIATION /14Z WEDNESDAY THROUGH SUNDAY/...
Snow showers will focus on and near the Tug Hill east of Lake
Ontario through morning. Expect mainly MVFR Cigs across the
region except for IFR at JHW and over the Tug Hill in steadier
snow.

Snow showers will taper off today, with gradually improving
conditions during the day. By early evening, another weather system
will spread rain to mainly snow across the region and bring a return
to MVFR/IFR conditions.

Outlook...

Thursday...MVFR/IFR in rain or snow.
Friday...Mainly VFR with a chance of rain/snow showers.
Saturday...Mainly VFR.
Sunday...VFR.

&&

.MARINE...
A southwest to west wind will continue across the lakes this
morning, generally in the 15 to 25 knot range, before diminishing
from west to east this afternoon and evening. Tonight winds will
turn to the north while increasing into Thursday morning. Winds will
likely reach SCA levels on Thursday in northwesterly flow.

A period of more tranquil conditions will likely come this weekend
into early next week as high pressure moves over the lower Great
Lakes.
