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 Buffalo, NY wrote its last area forecast discussion before this gale warning went out at Sep 30, 7:38 AM EDT, 5 hours 49 minutes earlier.

Area forecast discussion, Sep 30, 7:38 AM EDT, 5 hours 49 minutes before
Area Forecast Discussion
National Weather Service Buffalo NY
738 AM EDT Wed Sep 30 2020

.SYNOPSIS...
Widespread rain will transition to lake effect rain east and
northeast of the Lakes this morning. Lake effect rain will continue
east and northeast of the Lakes through Friday. Cool weather
continues through the rest of the week.

&&

.NEAR TERM /THROUGH TONIGHT/...
Regional radar shows lake effect rain showers moving onshore
east of Lake Erie this morning. Brief heavy downpours are
expected through the morning commute. Lightning has been
observed over the Lake and briefly over the City of Buffalo
this morning. Can't rule out more lightning as more lake showers
stream into Metro Buffalo and the Northtowns this morning. A
band of light rain associated with a departing low pressure
system will track across eastern Lake Ontario and the North
Country this morning.

An upper level trough will settle across the Great Lakes and
Northeast through tonight. Strong, southwest flow will move into the
region while surface low pressure over southern New England deepens
and quickly moves into the Canadian Maritimes this morning. Cool air
with 850mb temperatures around +4 C will provide enough support for
lake induced rain showers today. Southwest flow along the long axis
of Lake Erie and deep layer moisture with equilibrium levels around
20k feet will allow lake showers to become organized northeast of
Lake Erie into this afternoon. Thunder will be possible through the
early afternoon. Localized rain amounts of 0.5 to 1.5 inches are
possible northeast of Lake Erie today. Very windy conditions are
expected today with gusts near 40 mph northeast of Lake Erie. These
strong winds will allow lake showers to move inland towards
Rochester Metro and eventually into the eastern Lake Ontario region.
Lake showers are also expected off Lake Ontario and into the Saint
Lawrence northern Tug Hill region. Localized amounts of up to a
quarter inch are expected across the northern Tug Hill region today.

Southwest winds will become more southerly by this evening as a
shortwave trough approaches from the western Great Lakes. Lake bands
will shift to the north in response to the wind shift leaving a
majority of the forecast area dry. This won't last long as the
shortwave trough coupled with upstream moisture causes widespread
showers to move across the region tonight. Winds will go back to
southwest and lake enhancement is expected northeast of the Lakes
overnight. Can't rule out thunder northeast of the Lakes this
evening.

Temperatures will reach the low 60s today and fall into the 40s
tonight.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
Lake effect to east of both Lake Erie and Lake Ontario will be
ongoing on Thursday morning, though coverage may be less than what
occurs tonight as area will be between shortwaves to enhance the
lake effect. Gradually ramped pops upward late Thursday especially
closer to Lake Erie with approach of stronger shortwave and a
secondary cold front. As winds back more southwest ahead of the
front, expect the lake effect to focus farther northeast of Lake
Erie maybe even as far north as northern Erie county into Niagara
County. More favorable environment with deeper moisture should
result in some thunder in the strongest part of the lake effect
bands.

Eventually, lake effect will become more energized off the eastern
end of Lake Ontario once the shortwave rotates across later evening
into the overnight hours Thursday night. Possible that with winds
even more backed than over Lake Erie, most of the activity will only
impact northern Jefferson county toward the St. Lawrence River
valley. Once the shortwave trough settles directly across Lake
Ontario, models still insisting a lake induced sfc low forms over
eastern section of Lake Ontario by daybreak Friday. Such a scenario
is plausible given the more than ample over-water instability (H85
temps +3c giving lake/air delta t/s 15c). Exactly where the low
develops is uncertain, but possible that lake effect would shut down
for southeast portion of Lake Ontario at least to start Friday
morning with offshore winds while it would be quite frisky and
widespread over rest of Lake Ontario due to the enhanced convergence
with the low.

Eventually, later Friday morning the low is forecast to shift east
off the lake and so would expect lake effect to expand along much of
Lake Ontario. The lake effect combined with daytime heating should
allow showers to expand all the way into the Finger Lakes. Back off
Lake Erie, passage of the front tied to the low will allow winds to
veer to more west/northwest, so the lake effect will eventually
settle more into Southern Erie county and the western Southern Tier.
By afternoon on Friday, behind the front, forecast soundings show
inversions and overall lake equilibrium levels lowering steadily
into Friday night. Thus, lake effect will become less in coverage
and will weaken in intensity across the board by Friday night. Even
so, expect some lake effect to persist on northwest flow over parts
of the Southern Tier and especially to southeast of Lake Ontario
into the Finger Lakes. Where skies can partially clear out later
Friday night away from these areas, could see temps drop into middle
30s.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
Broad upper level troughing will reside over the eastern third of
the country Saturday before a potent shortwave passes through the
trough for the later half of the weekend and first part of the work
week. Meanwhile down in the lower layers of the atmosphere, high
pressure will push in across the eastern Great Lakes and Northeast
Saturday into Saturday night which will promote some drier
conditions during this time. However, 0C temperatures at 850mb will
promote the continuance lake induced instability and thus lake
effect rain showers will be possible during this time especially to
southeast of Lake Ontario.

High pressure will continue to push east into the Northeast Sunday,
which will keep the majority of the day dry. Temps on Saturday
night could drop below freezing in favored cold spots if clouds
are thin enough. The next system associated with the aforementioned
potent shortwave aloft will make its way across the Central
Plains and into the eastern Great Lakes late Sunday and into
Monday. Expect chances for rain showers to increase from west to
east during Sunday night through Monday. Rain chances will
diminish from west to east Tuesday as the surface low pressure
system departs the eastern portions of the region.

Temperatures will remain below normal for most of the period before
returning to normal by Tuesday.

&&

.AVIATION /12Z WEDNESDAY THROUGH SUNDAY/...
Lake effect rain showers will stream into western NY this
morning. Mostly VFR cigs at the moment but MVFR cigs are
possible in lake showers. Brief heavy downpours are expected in
lake showers and can't rule out lightning near KBUF today. Low
clouds are present across the higher terrain this morning
resulting in IFR at KJHW. These clouds should mix out towards
mid morning.

Light rain with MVFR cigs will move through KART this morning.
Lake effect showers will approach the terminal today however
most of the activity will stay to the northwest through the
afternoon. Brief periods of MVFR and heavy downpours are
possible.

Very windy today with southwest wind gusts near 30 to 35kts.

Lake induced rain showers continue this evening with most of the
activity northeast of the Lakes.

Outlook...

Thursday and Friday...MVFR with a chance of showers.
Saturday...VFR/MVFR with a chance of showers.
Sunday...Mainly VFR. Chance of showers late.

&&

.MARINE...
Winds and waves will ramp up this morning and will remain high
through Thursday. High-end small craft advisories, with winds over
25 kts across much of the area and waves over 6 feet at the east
end of the lakes, remain in place as outlined below.

The much colder air mass flowing across the warmer waters of Lake
Erie and Ontario will result in the potential for waterspouts the
rest of the week.
