The episode as NWS BUF wrote it up.
Most of the area was in the warm sector dry slot during the morning hours. Storms developed along a pre-frontal trough around midday and moved east across the area. The axis of greatest instability as the pre-frontal trough moved through the region was the Southern Tier to Northern Finger Lakes and North Country. The lowest severe weather risk was across the Niagara Frontier including the Buffalo metro area due to lake shadowing. Precipitable water values increased to near 2 inches, with dew points approaching 70 degrees ahead of the storms. This also made the risk for heavy rainfall in any thunderstorms a concern. Storms did produce high rainfall rates, but they were moving at a fast enough pace that the overall flooding threat was limited. There were a few discrete cells that formed east of Lake Ontario around midday that produced some wind damage in Lewis County. Meanwhile, the main line of storms associated with the pre-frontal trough initiated along a line stretching from Lake Ontario southwest across Lake Erie into eastern Ohio. This line of storms just took off from there with bowing segments and some supercellular development occurring basically across the entire area.

Area Forecast Discussion
National Weather Service Buffalo NY
156 PM EDT Mon Jun 21 2021
.SYNOPSIS...
Very unsettled weather this afternoon and evening will give way to
notably cooler and less humid conditions in the wake of a cold front
for Tuesday and Wednesday. The upcoming spell of fair dry weather
will persist through much of the work week before fairly widespread
showers for the upcoming weekend.
&&
.NEAR TERM /THROUGH TUESDAY NIGHT/...
...SEVERE THUNDERSTORM WATCH IN EFFECT THROUGH 8 PM...
Warm and unstable environment ahead of an approaching cold front
will support fairly widespread thunderstorm development during the
remainder of the afternoon into this evening. While all of western
and north central New York is in a severe thunderstorm watch until 8
PM...the greatest risk for severe weather will be across the
Southern Tier...Genesee valley and Finger Lakes region. The main
severe weather threat will be damaging straight line winds.
The showers and thunderstorms will drop off from west to east
tonight in the wake of a strong cold frontal passage. Notably cooler
and less humid air will charge into the region overnight with temps
averaging 10 to 15 deg f lower than those from last (Sun) night.
Mins will range from the 40s in the Srn Tier and on the Tug to 50-55
elsewhere.
Unseasonably cool air will be in place across our region on Tuesday
with H85 temps in the vcnty of +2c. Any breaks in the cloud cover
will just yield to 'self destruct sunshine' during the early
afternoon...then true clearing will become established as drier air
below H7 mixes during the mid and late afternoon. Highs will only be
int he low to mid 60s...with some of the higher terrain not breaking
out of the 50s. These readings will be 10 to 15 degrees below normal
during the highest sun angles of the year.
Fair chilly weather can be expected Tuesday night as high pressure
will pass to our south. Mins will be in the 40s away from the lakes...
with some 30s possible in the colder Srn Tier valleys.
&&
.SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/...
Wednesday, surface high pressure slowly drifts to our south and then
off the Northeast coast Wednesday night. A weak shortwave looks to
pass over southern Lake Ontario sometime Wednesday morning, which
may bring enough of a small uptick in moisture to bring a couple of
weak pop-up showers to the area. Given that this feature looks
fairly muted and the airmass over the region will be mostly dry,
have added only slight chance PoPs for southern Lake Ontario
Wednesday morning. Otherwise, a gradual warming trend will return as
southwesterly flow develops on the northwestern peripheral of the
high. Highs will reach the low to mid 70s Wednesday, with mid 60s up
on the Tug Hill.
High pressure and weak upper level ridging continues to pull away
from the New England coast Thursday as dry conditions persist. With
the region closer to the western edge of the surface high,
strengthening southerly flow will allow the warming trend to continue.
Highs across the area will generally settle in the mid to upper
70s, with mid 80s across the Lake Plains owed to weak downslope
flow off the higher terrain. Shower chances will slowly increase
from west to east in the second half of Thursday night ahead of
a trough axis stemming from a closed low over Georgian Bay, though
the vast majority of the night should remain dry. Increasing warm
air advection, cloud cover, and continued downslope flow will help
moderate overnight temperatures in some areas. Lows will dip into
the mid to low 60s on the lower terrain south of the lakes, with
mid 50s elsewhere.
&&
.LONG TERM /FRIDAY THROUGH SUNDAY/...
The next upper level trough will drop across the Great Lakes and the
Northeast Friday through Monday, all the while a few shortwaves will
also rotate through. As it stands currently, the ridge exiting east
aloft Friday will keep the majority of the area dry. However, a cold
front associated with the upper level trough aloft over the Great
Lakes will continue to cross the Great Lakes before entering Western
New York late Friday night into Saturday. Thus, expect showers and
thunderstorms to sweep across the area from west to east overnight
Friday through Saturday. Model guidances continue to progress the
trough and frontal zone slowly with its moisture being fed from the
Gulf of Mexico due to the southwesterly winds. This will bring the
much needed rain to the area.
Looking further ahead, model guidance packages continue to push
through a few more shortwaves while the trough is overhead. As such,
chances for rain and thunderstorms will continue through the
remainder of the weekend and into the start of the new work week.
&&
.AVIATION /18Z MONDAY THROUGH SATURDAY/...
While VFR conditions will be in place for the majority of the region
this afternoon and evening...the main concern will be an increasing
coverage of strong to potentially severe thunderstorm activity. Sites
that pick up any of these storms will experience a 30-90 minute period
of MVFR weather.
Tonight...generally VFR weather will give way to MVFR cigs. This will
especially be the case across the higher terrain of the srn Tier
and Finger Lakes where MVFR cigs will be possible at anytime after
00z.
Fairly widespread MVFR cigs at the start of Tuesday will slowly
improve to VFR for the afternoon.
Outlook...
Wednesday and Thursday...VFR.
Friday...VFR. A chance of showers.
Saturday...VFR to MVFR with showers becoming likely.
&&
.MARINE...
South to southwest winds will increase ahead of a cold front today,
especially on Lake Erie. Small Craft headlines are outlined below.

winds, hail and frequent lightning.

Thunderstorms will develop this afternoon and will move across the area through early evening. Across the Niagara Frontier, including the Buffalo metro area, scattered storms will bring a lower but still some risk for severe weather. This will primarily be between 1 and 4 p.m. There's a greater risk for severe weather across the Western Southern Tier, Genesee Valley, Western Finger Lakes, and eastern Lake Ontario regions. The greatest risk for severe weather at these locations will be between 2 and 6 p.m. Damaging winds will be the primary threat associated with these thunderstorms. Large hail is also possible, in addition to brief torrential rainfall and dangerous cloud to ground lightning. If you have outdoor plans this afternoon into early this evening, keep a close eye on forecasts and warnings. Have a plan to move to a sturdy shelter if threatening weather approaches your location.
