The episode as NWS BUF wrote it up.
Sunshine over the Finger Lakes on the brought sufficient sunshine to bring ample instability to a very moist air mass that was in place. The atmosphere was not highly sheared, however. Thunderstorms first developed east of Lake Ontario with some degree of rotation involved. The second round of storms was a line of convection that rolled in from Lake Erie during the early evening. Winds aloft were around 40 knots and with a linear structure, this resulted in localized gusts in the Lake Erie marine layer as well as some trees down in the Buffalo.

NWS Buffalo, NY wrote its last area forecast discussion before the first event at Aug 8, 8:47 AM EST, 4 hours 49 minutes earlier.
Area Forecast Discussion National Weather Service Buffalo NY 947 AM EDT Mon Aug 8 2022 .SYNOPSIS... A warm and humid airmass will remain over the region through tonight, then a passing cold front will usher in a cooler and less humid airmass. Showers and thunderstorms may produce heavy rainfall at times through tonight. Another cold front will move across the region on Thursday, bringing cooler and more comfortable weather through the weekend. && .NEAR TERM /THROUGH TONIGHT/... A weak shortwave/pre-frontal trough is responsible for showers across northern Ohio, and following its progression these will enter Western NY this morning before moving across Central NY late this afternoon. Scattered showers and possibly a thunderstorm across Western NY mid-morning through early afternoon. These will arrive before the southwesterly flow becomes established on Lake Erie, so lake shadowing will not keep Buffalo and much of the Niagara Frontier rain-free until later this afternoon. Expect an increase in areal coverage and intensity east of the Genesee Valley since the wave will arrive during peak diurnal heating with more instability in place. Precipitable water values around 2 inches will support locally heavy downpours. Forecast wind fields suggest at least limited wind shear which may support an isolated strong thunderstorm by the time storms move east of Lake Ontario. Also, with surface low pressure and a cold front remaining to our north, the region will remain in a hot and humid air mass for one more day. While it won't be quite as hot as yesterday, heat index values will still reach the mid to upper 90s in Wayne/Ontario/ Oswego/N Cayuga counties where a Heat Advisory is in place. Unlike the past few nights, the convection will NOT fade away with the setting sun. The front will slowly settle south across the area, which will maintain the potential for showers and thunderstorms tonight...along with the risk for tropical downpours. There also will be a decent amount of wind shear ahead of the cold front, however it will be nighttime with limited surface based instability in place. && .SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/... A cold front will be tracking south across western and north central NY Tuesday morning. Showers and possible thunderstorms will be ongoing Tuesday morning mainly south and east of Interstate 90 across western NY. Showers will also extend into the southern Tug Hill region. The front will slowly track south towards the New York/Pennsylvania border with showers tapering off from north to south through the afternoon. Highs will reach the mid to upper 70s. The front slows down and showers may linger along the NY/PA border thorugh the evening hours. Cooler and drier air will move into the region Tuesday night. Lows will fall to the upper 50s to low 60s. The cold front will move further south Wednesday. A shortwave trough will cross the eastern Great Lakes region and increasing clouds and a few showers are possible especially across north central NY. Highs will reach the upper 70s to low 80s Wednesday. High pressure will move into the region Wednesday night while another cold front approaches from the northwest. Shower chances increase across the Niagara Frontier late Wednesday night. Lows will fall into the mid to upper 50s. && .LONG TERM /THURSDAY THROUGH SUNDAY/... The pattern becomes amplified late in the week with a strong ridge building across the Rockies and a deepening trough across the Northeast. A cold front will track across the eastern Great Lakes region Thursday and increasing moisture and strong surface convergence will increase chances for showers along the front Thursday. Cold air advection will last through Thursday night with H85 temperatures falling to +7C overnight. Can't rule out some lake induced showers Thursday night into Friday mainly southeast of Lake Ontario. The upper level trough will sharpen overhead with the axis passing across the region Friday. Daytime heating with steep low level lapse rates may lead to some afternoon showers especially east of Lake Ontario. High pressure builds into the region Friday night. Surface high pressure dominates Saturday through Sunday with dry and comfortable weather. Temperatures will average in the mid to upper 70s for highs Thursday- Sunday. Friday will likely be the coolest day of the period with highs in the upper 60s across the higher terrain to the mid 70s across the lake plains. Lows will average in the 50s. && .AVIATION /14Z MONDAY THROUGH FRIDAY/... MVFR cigs will be common across the far western counties today with showers becoming likely along with the chance for thunderstorms. Cigs will lower to MVFR levels across the North country during the course of the afternoon with the Finger Lakes region (ie. KROC) being the last area to experience MVFR weather. A cold front will drop slowly southward across the region tonight. This is likely to produce showers with some thunderstorms with its passage. MVFR or lower flight conditions possible in thunderstorms. Lowering cigs following the wind shift, with IFR conditions developing at most locations between 08Z and 11Z. Outlook... Tuesday...VFR/MVFR with a chance of showers and thunderstorms, especially across the Southern Tier. Wednesday...Mainly VFR but with a chance of showers. Thursday and Friday...VFR. && .MARINE... A southwest wind will increase today, supporting small craft headlines for Lake Erie and the Upper Niagara River. Winds may drop off a bit early evening before picking up again right ahead of a cold front approaching from the north. Choppy but below headline conditions on Lake Ontario. Showers and thunderstorms may produce locally heavy rain and gusty winds today and tonight. Winds will shift to the northwest behind the front late tonight, but will only run 10 to 15 knots. Then high pressure will build on Tuesday and Wednesday with negligible wind and waves. && .BUF WATCHES/WARNINGS/ADVISORIES... NY...Heat Advisory until 6 PM EDT this evening for NYZ004>006-014. MARINE...Small Craft Advisory until 4 AM EDT Tuesday for LEZ020-040-041. && SYNOPSIS...Apffel NEAR TERM...Apffel/RSH SHORT TERM...HSK LONG TERM...HSK AVIATION...Apffel MARINE...Apffel
