The episode as NWS PBZ wrote it up.
A line of mostly sub-severe thunderstorms preceded a cold front during the evening hours of July 1st. Only one instance of wind damage was noted in Armstrong County.

NWS Pittsburgh, PA wrote its last area forecast discussion before the first event at Jul 1, 8:57 PM EST, 18 minutes earlier.
Area Forecast Discussion National Weather Service Pittsburgh PA 957 PM EDT Fri Jul 1 2022 .SYNOPSIS... Showers and storms are possible until the passage of a cold front Saturday morning. Afterwards, expect a return to seasonable and dry conditions. && .NEAR TERM /UNTIL 6 AM SATURDAY MORNING/... A broken line of convection will move slowly to the east southeast ahead of an incoming cold front and along a passing shortwave trough. This feature will mainly generate heavier rain and lightning, with no wind threat as the gust front has advanced ahead of the line. The rest of the evening will be characterized by additional shortwaves moving through the upper trough slowly pushing the cold front southeast into Saturday morning. Enough moisture, residual elevated CAPE, and jet/cold front supported lift should be enough for scattered showers and an isolated thunderstorm, though the lack of any strong parameter hints at coverage remaining spotty. && .SHORT TERM /6 AM SATURDAY MORNING THROUGH SUNDAY NIGHT/... The front will pass through the Pittsburgh metro Saturday morning, move south, and exit the region by Saturday afternoon. This may allow the chance for some isolated showers and storms, primarily south of I-70 in PA and WV through the morning. Severe weather is not expected. Cold, dry air advection in northwest flow will leave the rest of the weekend pleasant. Some high clouds may linger for the weekend in the wake of the trough and ahead of a low that will pass to our south. Daytime highs and nighttime lows for the weekend will return to seasonable conditions, and no precipitation is expected as a high begins to build from the west. && .LONG TERM /MONDAY THROUGH FRIDAY/... A return to warm, moist advection in southwest flow will occur on Independence Day. At this time, ridging and a warm air cap seem likely to suppress convection, but conditions will be slightly warmer and muggier than the prior days. Next week will be characterized by rather persistent troughing over the northeast and ridging over the interior US. This is indicative of upper-level northwest flow, and lower-level, moist, southwest flow. At this time, it seems that most models indicate that this pattern will amplify throughout the week, leaving Pittsburgh downwind of the ridge axis. While this is synoptically favorable for drier conditions, the passage of a couple of shortwave troughs may incite a couple precipitation chances early-to-mid week, and again mid-to- late week. Because the region is located along an inflection point in the 500mb pattern, the position and strength of the developing ridge and adjacent trough will largely affect daily temperatures and precipitation chances, thus there is still some uncertainty in the long term forecast. && .AVIATION /02Z SATURDAY THROUGH WEDNESDAY/... After a general lull in convective activity this afternoon, more widespread showers and a few storms are expected later this evening into tonight as a cold front sinks southward across the region. Cigs will lower into the MVFR range at most terminals with increasing moisture and precipitation. MVFR ceilings may linger through sunrise, with improvement to VFR by midday Saturday. .Outlook... Mainly VFR conditions will then be expected from later Saturday through early next week. && .PBZ WATCHES/WARNINGS/ADVISORIES... PA...None. OH...None. WV...None. && SYNOPSIS... NEAR TERM...
