The episode as NWS BUF wrote it up.
A weak surface low tracked across western NY to the northeast of Lake Ontario from the afternoon to the late evening hours. Building instability and increased wind shear ahead of the low supported clusters of severe thunderstorms beginning late in the afternoon across the northern Finger Lakes. Additional northward moving severe storms that exhibited low-level rotation formed early in the evening in a narrow corridor from central New York to areas east of Lake Ontario. In addition to wind damage and large hail, two tornadoes occurred over northeast portions of Oswego County and southern portions of Lewis County during the evening. Eventually, storm surveys confirmed that one of these tornadoes near West Leyden New York to Turin New York tracked 16 miles with observed damage indicating peak winds up to of 140 mph or EF-3 strength. After the tornadic storms diminished, additional storms with very heavy rain tracked over portions of Oswego and Lewis counties from late evening into the overnight hours. These storms which trained over similar areas produced 3 to 4 inches of rain with multiple roads flooded and a few roads entirely washed out.

Area Forecast Discussion
National Weather Service Buffalo NY
229 PM EDT Mon Aug 7 2023
.SYNOPSIS...
Low pressure will track into the Lower Lakes today with another
round of showers and thunderstorms...some of which could produce
gusty winds, hail, and heavy rain. Additional showers and
storms will be possible tonight through Tuesday as the low
pressure system slowly moves through the region. Showers will
then taper off from west to east by Tuesday night as the low
moves off into New England. High pressure builds in Wednesday
with a brief return to quiet dry weather.
&&
.NEAR TERM /THROUGH TUESDAY/...
Current satellite and radar is showing a generally weak MCV
over far western NY, tracking northeast toward Lake Ontario.
With the system moving into the WNY area, showers and some
thunderstorms are starting to develop over the area. This will
continue through the evening as the system tracks across the
area along with its trailing convective boundaries. Mainly clear
conditions still from the Genesee Valley to the North Country
combined with peak daytime heating will make these areas most
favorable for strong to severe thunderstorms. Lining up with
most of the forecast area being in a 'Slight Risk' for severe
thunderstorms, except the far western NY area along the Canadian
and Lake Erie boundaries. Current temperatures across the area
vary from the mid-60s to low 70s for rain cooled areas, to the
low to upper 80s for areas not having seen any rain yet this
afternoon.
The main change will be how much sunshine has developed this morning
into the afternoon and how much more instability that will
contribute for the system crossing the area. Earlier KBUF, KIAG, and
KJHW sounding profiles only generate 500-1000 j/kg by this afternoon
into this evening, but with more sunshine than expected that number
should increase some, especially to the east with the clearing
coming during peak heating time. SPC guidance pushes CAPE values to
around 1250 J/kg this afternoon for eastern portions of the area.
Guidance still shows a jump in the low level wind field this
afternoon and decent 0-6 km shear of 30 to 40 knots. This is likely
the arrival of the convective wave moving across the area.
Additionally...there is no shortage of moisture to work with as PW
values will continue to hover in the 1.75 to 2.00 range. WPC has
place our area in a Marginal and Slight risk for excessive rainfall.
Given the soupy environment the potential exists for flash flooding.
Looking east...from the Genesee Valley into the North Country CAPE
values do improve to 1000 to 1500 j/kg and then especially southeast
of the region across PA this afternoon. This is where the potential
for severe weather is greater. SPC has highlighted all of our area
in a slight risk for severe storms with the main threats being gusty
winds, hail, and heavy rain. Afternoon highs in the low to mid 80s
expected for most of the area.
Tonight...showers and storms will continue to be possible but
will fade in coverage. As the low slowly churns east across the
Lower Lakes showers will then fill back in across western NY late
under WNW cyclonic flow as we head into Tuesday. Otherwise...a muggy
night is expected with lows in the mid to upper 60s.
Tuesday, showers will increase with daytime heating and the axis of
the trough crossing the area during the morning and afternoon.
Moisture values will decrease through the day, so any showers that
continue into the afternoon should be on the lighter side.
Temperatures on Tuesday will be in the low to mid 70s, with a few
mid to upper 60s possible for the higher terrain.
&&
.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/...
Low pressure centered over New England Tuesday night will pull east,
supporting wrap around moisture to linger across the North Country
and Saint Lawrence Valley. With the low pulling northeast of the
area, the lingering showers across the North Country will gradually
come to end throughout the night.
Surface high pressure over the southeastern United States will
expand its ridge across the area Wednesday and provide a break in
the wet weather.
The next upper level low will dive southeast across the Ontario
province Wednesday night and begin to pull northeast across the
Quebec province Thursday night. The passage of this upper level
feature will support a surface low to closely follow in its path.
However, its attendant cold front will pull east across the area
Thursday and Thursday night supporting another round of showers and
afternoon thunderstorms. Rainfall with some of these showers and
storms may be moderate to heavy at times as PWAT values are trending
between 1.50 and 1.75 inches. Guidance continues to support a
secondary surface low and potent shortwave to track south of the
area and along the front, increasing the rainfall amounts across the
Southern Tier. Showers will then taper off from west to east behind
the passing of the front Thursday night.
&&
.LONG TERM /FRIDAY THROUGH SUNDAY/...
Subtle upper level ridging Friday will support high pressure to
slide east across the Great Lakes and therefore provide a dry day
Friday and into Friday night.
The next upper level trough will slide across the Great Lakes Friday
night through Saturday, supporting a surface low and frontal
boundary to track across New York State and therefore expect showers
and diurnal thunderstorms Saturday. Showers will continue Sunday as
a cold front finishes crossing the ares.
As the low pulls northeast Monday, showers will taper off though
with the upper level troughing and cooler temperatures aloft some
diurnally driven showers and thunderstorms can not be ruled out.
Otherwise, temperatures throughout the end of the week and into the
start of the new work week will range within a few degrees of normal.
&&
.AVIATION /19Z MONDAY THROUGH SATURDAY/...
Mainly VFR CIG...with some MVFR/IFR across the higher terrain to
include KJHW. A brief break in the clouds will continue through late
afternoon for eastern areas. An MCV over WNY will track NE and will
bring a round of showers and storms this afternoon into the early
evening.These storms will have the potential to produce heavy rain
and gusty winds...with localized IFR/LIFR restrictions.
Tonight...showers and some thunderstorms will continue with MVFR to
IFR/LIFR CIGS across the higher terrain of the S.Tier and east of
Lake Ontario.
Tuesday, mainly MVFR/IFR conditions expected, with showers can be
expected especially over the higher spots. Some improvements later
in the day can be expected
Outlook...
Tuesday night...MVFR to VFR with showers ending.
Wednesday...VFR.
Thursday...VFR/MVFR with scattered showers and thunderstorms.
Friday...VFR.
Saturday...VFR/MVFR with showers possible
&&
.MARINE...
Winds will be 5 to 15 mph out of the SSE which will produce light to
moderate chop on the lakes. Low pressure will approach the lakes
this afternoon with increasing chances for showers and
thunderstorms. Some of the storms may produce strong gusty winds,
which could result in localized higher wave action.
Otherwise, winds will increase tonight and remain elevated
through Tuesday night as a wave of low pressure moves by the
lakes. Have issued a small craft advisory for strengthening
WNW winds on Lake Erie from 04Z through Tuesday. Additional
SCAs will likely be needed for Lake Ontario on Tuesday into
Tuesday night. These stronger winds and higher waves will also
likely result in another round of dangerous swimming conditions
in all or most of our nearshore waters Tuesday into Tuesday
night.

The National Weather Service in Buffalo used Sentinel-2 satellite|imagery and found tornadic damage in Lewis County. A damage scar |was found using difference techniques of satellite imagery. The |scar was found in a wooded area east of North Osceola Road in the |Town of Osceola. A damage survey could not be conducted due to |limited access into the wooded area. The tornado is thus rated|EF-Unknown.
Trees were downed on wires along North Osceola Road.
Multiple trees were downed.
The National Weather Service in Buffalo completed a storm survey in Lewis County for damage that is confirmed to be tornadic from Monday evening. Initial damage from the tornado occurred in the Town of Lewis to the west of West Leyden along Mud Lake Road that included uprooted and snapped hardwood trees, significant damage to two homes that included roof uplift and near total removal, a wall blowout of a garage, and the complete destruction and shift from the foundation of a barn. Damage in the initial portion of the track generally peaked at EF-2. The tornado then continued northward and crossed Fish Creek Road with damage to another home that removed the roof and caused significant damage in the walls of the second level of the home. It also did significant damage to a second barn and snapped many hardwood trees.
After moving north of Fish Creek Road, the tornado crossed a large swamp with evidence of full defoliation of a few hardwood trees in the swamp. Tornadic damage become less continuous north of this point without good road access to the track through swampy land. Convergent track damage again resumed well southwest of the Town of Turin, hitting the town water tower. The tornado then continued northward as it paralleled West Road. Continuous uprooting, snapping, and occasional defoliation of hard and softwood trees was evident for a long portion of the track until it reached Snow Ridge Ski Resort. Upon reaching Snow Ridge Ski Resort, tree damage increased to snapping of hardwood trees at the rootline and some defoliation. On the ski resort land, all of the chair lift metal cables failed, some chair lift structures were overturned or damaged, and the track of damage greatly widened as the storm continued north- |northeastward. The greatest damage along the entire track of the tornado was from Snow Ridge Ski Resort to the West Wind Motel in Turin. Several structures saw completed roof failures, interior wall failures, window failures, and a one multi-story building was shifted from its foundation with its entire roof removed. The tornado lifted after affecting the West Wind Motel with damage ceasing from this point as it crossed State Route 26.
Road was flooded due to heavy rain.
Parts of Highmarket Road were washed out.
A culvert was washed out and a road was closed due to flooding.
