The episode as NWS BUF wrote it up.
Clusters of thunderstorms formed during the afternoon. An interesting aspect was that the storm motion has storms moving from east to west due to the counterclockwise flow around an upper low over the Middle Atlantic States. A few clusters of storms increased in intensity and produced isolated damaging wind gusts with some trees down, especially across Ontario County. Torrential rain also occurred with the slow-moving storms.
The local office's own words before the first event, 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 the first event at Aug 16, 1:20 PM EST, 20 minutes earlier.
Area Forecast Discussion National Weather Service Buffalo NY 220 PM EDT Tue Aug 16 2022 .SYNOPSIS... A large upper level storm over the region will keep a fair amount of clouds in place into Thursday while maintaining the opportunity for some needed rainfall. Most of the showers and scattered thunderstorms will be experienced during this afternoon and again Wednesday afternoon. Along with the return of sun filled skies on Friday...temperatures will climb well above normal into the low to mid 80s. && .NEAR TERM /THROUGH WEDNESDAY NIGHT/... A large upper level storm system centered over Pennsylvania and New York late today will SLOWLY drift east to New England tonight and Wednesday...as twin vortices will orbit about its center. This system will maintain a wealth of clouds across our forecast area in the process...while H85 temps of 12c and H5 temps of -15c will keep the environment conditionally unstable. This instability is being showcased this afternoon with convection over the Genesee valley...where despite the lack of any shear...tall but near vertical...slow moving convection is producing torrential downpours along with some pea sized hail. This and...any other afternoon convection...will die off late this afternoon and evening but will become re-established across the region Wednesday midday and afternoon. The mainly diurnally driven shower/storm activity will then once again give way to rair weather Wednesday night. Max temperatures will average a a little below normal for the remainder of the afternoon...as well as on Wednesday...while overnight lows will be right near normal mid August levels. && .SHORT TERM /THURSDAY THROUGH THURSDAY NIGHT/... The aforementioned upper level closed low over New England will meet up with a coastal low Thursday, where by Thursday night both features will become vertically stacked. This being said, the lower Great Lakes region will remain of the backside of the low pressure system which will produce a marginal lake response as winds back more north-northwest Wednesday night into Thursday and therefore kept the slight chance and chance for lake effect rain showers Wednesday night into Thursday. Additionally, later on Thursday diurnally driven showers/thunderstorms will be possible once again. Thursday night, the stacked low pressure system will continue to progress north into the Canadian Maritimes allowing for some upper level ridging and surface high pressure to spill across the Great Lakes. With the incoming ridging and surface high pressure, expect mostly dry conditions Thursday night. && .LONG TERM /FRIDAY THROUGH MONDAY/... Another potent shortwave trough will dive south from the Canadian Prairies and into the Upper Midwest Friday. Similar to the low pressure system earlier in the work week, this feature will closely follow suit by closing off and slowing down its progression across the Upper Mississippi Valley through the first couple of days of the weekend. On the bright side, the slowing progression of the trough will support ridging, surface high pressure and consequently a period of dry weather across the region Friday through most of the day Saturday. As of 00Z model guidance packages arrive, the weakening upper level low is progged to track east late Saturday and Saturday night which would support a chance for some scattered showers Saturday night, mainly across Western New York. Then increasing moisture along with diurnal heating will support better chances for showers and thunderstorms Sunday afternoon, though the best opportunity for showers and storms will arrive as the system nears the area at the start of the next work week. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/... While VFR conditions will be found at most of the TAF sites through this forecast period...a large upper level storm system will help to support scattered convection this afternoon and again on Wednesday (mainly after 16z). MVFR conditions could be found in the vcnty of any convection. Another time period to watch will be late tonight when some IFR criteria stratus and fog could develop across the Southern Tier. Should this develop...it would likely give way to VFR conditons by 14z. Outlook... Thursday...Mainly VFR. Chance of showers and isolated thunderstorms with local/brief flight restrictions. Friday and Saturday...VFR. Sunday...VFR, but with deteriorating conditions later in the day. && .MARINE... High pressure will remain anchored over Quebec through Wednesday, with general low pressure over the southeast states and along the east coast. This will maintain an extended period of northeast winds on Lake Ontario and Lake Erie. Sustained wind speeds will generally be 10-13 knots, producing a light chop at times. As we advance through tonight...H85 temps of 12c will combine with a convective depth of nearly 25kft to establish a minimal chance for waterspouts. Any shower activity over the lakes late tonight into Wednesday should be closely watched for possible waterspouts. && .BUF WATCHES/WARNINGS/ADVISORIES... NY...None.
