| 22:56Z | EF1 | KPBZ | PA | Beaver | New Galilee | The National Weather Service in Pittsburgh conducted a storm|survey in far northern Beaver County just northeast of New Galilee.|The damage was confined along either side of Fairlane Boulevard / |State Route 351. Majority of the damage was hardwood and softwood |trees missing large branches. One softwood tree was uprooted, which |was the damage indicator that warranted the EF1 rating. One of the |large branches fell onto a detached garage causing damage to the |roof. The tornado lifted prior to reaching the intersection of State |Route 351 and Big Beaver Boulevard. |
| 23:03Z | EF1 | KPBZ | OH | Jefferson | Emerson | The National Weather Service conducted a survey off Township Road|102 just southwest of Mt. Pleasant, Ohio. The damage was confined|to hardwood and softwood trees. They were either snapped at the |trunk, missing large branches, or uprooted. There was a 100 year |old oak tree that was uprooted. The only structure damage was to a|house, which loss less than 20% of its shingles. |Estimated Maximum Wind Speed...100 mph.|Estimated damage cost was provided by the local emergency manager. |
| 23:06Z | EF1 | KPBZ | OH | Belmont | Lamira | The National Weather Service surveyed three touch down points in|Belmont county.

| 23:11Z | EF1 | KPBZ | PA | Beaver | Hazen | The National Weather Service in Pittsburgh conducted a storm survey |in far northeastern Beaver County in Franklin Township eastward to |Harmony Township, Butler County. The damage, much like previous ones |for this event, was regulated to hardwood and softwood trees. There |was no structure damage observed along the track. ||Damage initially started on American School Road then east along |North Camp Run Road. The most intense damage was recorded farther |down American School Road where at least 30 hardwood trees were |uprooted or had large branches blown down. As the tornado continued down |American School Road, downed softwood trees and hardwood trees snapped |at the trunk were observed. The tornado lifted as it crossed into |Butler County just beyond the intersection of American School Road |and Scott Ridge Road. |
| 23:15Z | EF1 | KPBZ | PA | Butler | Middle Lancaster | This is a continuation of the tornado track that began in Franklin Township, Beaver County.

| 23:30Z | EF2 | KPBZ | PA | Washington | Independence | A NWS damage survey confirmed that an EF-2 tornado, with winds|peaking near 130 MPH, tracked through western Washington County|on the evening of October 21, 2021. The length was over 15 miles|long and the width varies in some areas but the maximum was between 600 |to 700 yards. This tornado was associated with the same circulation |that initially produced a tornado in Jefferson County, Ohio earlier. ||Weak tornado damage was first noted along Brashears Run Road with|a few fallen trees. The storm rapidly intensified along Indian |Camp Rd, where a mobile home had roof damage and a well-structured|deck was ripped and tossed into the neighbors yard. Many trees |were snapped and uprooted as well. Damage in this area was |consistent with winds speeds of 90-95 MPH.||The tornado continued east towards Hopewell Township. Noted roads|that had tree and structure damage, associated with EF-1 damage, |were along Short Cut Road, Scenic Drive, Raccoon Run Road, Possum Hollow|Road, Old Trail Road, Jefferson Avenue, Park View Drive, and |Oakleaf Road.||Peak intensity was reached near Willow Road and Lowry|Lane where a two story home had a roof completely torn off and |tossed about 100 feet and a few portions of the walls collapsed. |With closer inspection, a few of the foundation blocks were |shifted on both sides of the house. Peak wind was near 130 MPH in |this region. A few hundred feet away a farm building was |completely destroyed. As the tornado crossed Lynn Portal Road and |advanced along White Lane, a solid brick home lost the roof and |the attached garage. ||The tornado started to weaken, but still continued to hold near |100 MPH winds, as it tracked across McCarrell Road, Western Ave, |and towards the outskirts of the city of Houston, PA. The tornado |appears to have dissipated near North Main Street and Pine Ave |north of Houston, PA.||At least $600,000 of damage was noted by PEMA to four different structures.|The total cost of destruction was estimated by the NWS Storm Surveyor. |
| 23:33Z | EF0 | KPBZ | PA | Butler | Mt Chestnut | A damage survey confirmed a discontinuous tornado path causing|sporadic tree damage of varying intensity as it tracked across|central Butler County. The most significant damage was noted|along Woodcrest Road, where numerous trees were snapped or|uprooted and flagpoles were bent over by the wind. Damage was|consistent with wind up to 80 mph. This tornado was part of a|radar-indicated circulation that began in Beaver County. |
| 23:41Z | EF0 | KPBZ | PA | Allegheny | Emsworth | A damage survey confirmed that a brief tornado occurred in and|near the Mount Nebo Pointe shopping center. Damage at the Target|store included broken glass in the entry doors (which were sucked|outward by the wind), as well as damage to a sign on the west-|facing side of the store. Minor tree damage and tall grass|blowdown was noted on the eastern side of the shopping center and|tree damage was noted at the base of the hill on the western|side. The circulation lifted very soon after as it reached a|small gully to the east. Damage indicators were consistent with a|maximum wind speed of 70 MPH during this brief event. |
| 23:47Z | EF1 | KPBZ | PA | Allegheny | Allison Park | A damage survey confirmed that a tornado tracked across the|southern portion of Hampton Township, PA. This tornado was|associated with the same circulation that initially produced a|brief tornado earlier in Mount Nebo. Damage was first noted in the|area of Auld and Forest Avenues, in the form of light structural|damage to homes. The tornado strengthened on Linden Drive, with|several snapped hardwood and softwood trees, as well as the|uplift of a roof. Damage in this area was consistent with wind|speeds of 90 to 95 MPH. Snapped and uprooted trees were seen as|the tornado continued across Parkview Lane and then to Duncan|Avenue. Farther east, in the Church Hill area, snapped and|uprooted trees were observed, with one large tree on a house on|Cole Avenue, and some other minor structural damage where Cole|intersects with Miller Avenue as well as Cella Lane, representing|a rough tornado track width of 200 yards. The tornado weakened|considerably after it crossed Route 8 and into Bryant, before|causing more damage in the vicinity of Middle Road. Widespread|snapped hardwood trees were seen between John Giel Drive and|Green Valley Drive, and a cinder-block outbuilding was destroyed,|with debris being blown downwind 1/4 mile. Damage here was|consistent with 100 to 105 MPH wind. Tree damage continued ENE|into Hartwood Acres Park and then to Dorseyville Road, where the|damage path finally ended as the tornado dissipated. NWS|Pittsburgh is grateful to Hampton Township and Allegheny County|EMA for their assistance with this damage survey.||Damage cost was estimated using information from the local emergency manager. |
| 23:58Z | EF1 | KPBZ | PA | Washington | Gale | The National Weather Service conducted a survey off E Finley Dr in|Washington County. The damage path was oriented west-to-east near|a road that consisted of farms and residences. Damage consisted |of several snapped and uprooted hardwood trees, roof damage to a |shed, and a completely destroyed barn. Estimated Maximum Wind Speed...100 mph. |
| 23:59Z | EF1 | KPBZ | PA | Washington | Pleasant Grove | A NWS damage survey, conducted both by ground and aerial drone, |confirmed that an EF-1 tornado, with speeds ranging between 80 and|90 mph, tracked through eastern portions of East Finley township |on the evening of October 21, 2021. The tornado initially touched |down on open farmland approximately 0.4 miles west of Quaker Ridge|road, where drone footage discovered damage to several trees |along opposing tree lines, with a distinct scouring pattern |observed in the open pasture between them. The tornado continued |eastward through wooded area, producing the most significant |damage to a cluster of trees along Quaker Ridge Road adjacent to |the parking area for Pennsylvania State Games lands. At least 10 |mature trees of up to 8 inches in diameter were snapped anywhere |from 1/4 to 3/4 of the way up the trunk line. The tornado |continued east across Quaker Ridge road into the woodlands for |another 100 ft, producing lesser tree damage until dissipating. |This damage is coincident with a strong radar signature from both |the NWS Pittsburgh and Pittsburgh International Airport Doppler |radars. A thorough survey of the area several miles west and east |of this tornado yielded no additional damage. |
| 00:07Z | EF1 | KPBZ | PA | Washington | Thomas | A NWS damage survey confirmed that an EF-1 tornado, with winds|speeds ranging between 90 to 95 MPH, tracked through portions of|Peters Township in Washington County on the evening of October|21, 2021. The length was 1.5 miles and the width in some areas|was about 100 to 200 yards. This tornado was associated with the same |circulation that initially produced an EF-1 tornado in Jefferson |County, OH and an EF-2 in Hopewell Township a few miles to the |west. ||A few broken branches were noted along Thomas Road near|Peters Lake Park. However, the tornado quickly intensified as it|cross Hill Place Road. Trees were uprooted and snapped in the|vicinity of Springdale Road and Sunrise Lane. A number of new and|well-structured brick homes had window damage, a garage blown|out, shingle damage, and trees snapped. The tornado weakened and|dissipated just west of Bower Hill Road.||A detailed review by PEMA noted damage to 4 homes on Hill Place Road, |5 homes on Sunrise Road, 5 homes on Springdale Road, 1 home on |Buckingham Drive, and 2 homes on Sienna Trail. |||Damage cost was estimated by NWS Storm Surveyor. |
