The following events were reported: Tornado. These occurred near station USW00013739, approximately 32.5659 km away, between 2021-07-29 18:04:00 and 2021-07-29 18:12:00.Thankfully, no injuries or fatalities were reported. No significant property or crop damage was reported. Episode Narrative: A strong shortwave trough moved east-southeastward out of the Great Lakes region on July 29. An associated, strengthening surface low also tracked out of the Great Lakes and into upstate New York. A warm front associated with this low moved through most of New Jersey and eastern Pennsylvania during the late morning and early afternoon hours. This front, combined with the remains of widespread convection to the west from the previous overnight and morning hours, brought significant cloud cover to the eastern mid-Atlantic for much of the day on the 29th. This was mainly in the form of mid and high level cloud cover, however, and temperatures still warmed to near seasonal levels behind the warm front, allowing moderate to strong instability to build. Meanwhile, the robust surface and upper level disturbances approaching the region brought both strong forcing and unseasonably strong wind shear. By mid-afternoon, an unusually favorable convective environment existed over eastern Pennsylvania and New Jersey.||The result of this environment was a rare tornado outbreak across the area. Initially, during the mid-afternoon hours, mixed convective modes over east-central Pennsylvania produced a couple instances of damaging wind and brief tornadoes as storms attempted to overcome cloud cover and some light stratiform rain in the area. With time, as storms moved into better instability and a less contaminated environment over far eastern Pennsylvania and New Jersey, they took on more supercellular structures. Multiple cyclic supercells would go on to produce several tornadoes, three of them strong (EF2+) over eastern Pennsylvania and New Jersey. Convection persisted past the sunset hour with little to no loss in intensity due to the strong forcing. The only thing that put an end to the outbreak was the coastline, as storms moved offshore towards 9 to 10PM local time. Even offshore, one supercell continued to exhibit strong rotation and likely produced a strong waterspout for tens of miles over the Atlantic.||Fortunately, and miraculously, no serious injuries or loss of life occurred as a result of this outbreak. With the passage of a cold front late on the evening of the 29th, cooler, drier, and much less active weather would grace the region for several days as clean-up efforts began. A strong shortwave trough moved east-southeastward out of the Great Lakes region on July 29. Event Narrative: An EF3 tornado better known for its impacts it Bucks County, PA began briefly in Philadelphia County, PA. The tornado touched down near Southampton Road, Kelvin Avenue, and Trevose Road where it uprooted and blew down large limbs from a |few softwood and hardwood trees. The tornado then moved into Bucks County, with trees uprooted at the county line. The tornado which began in Philadelphia County crossed into Bucks County, where it would produce the majority of its impacts. After crossing the county line, the tornado continued between Trevose Road and Peyton Street |where additional tree damage occurred before crossing Lukens |Street. The tornado then very briefly crossed back into |Philadelphia County at the northern tip of Poquessing Valley Park |where a few trees were uprooted. The tornado then crossed back |into Trevose in Bucks County where it caused some minor cosmetic |damage to some homes in the Beechwood Estates neighborhood and |blew down several sections of vinyl fencing. Several small trees |were also snapped or uprooted in and just south and east of the |residential neighborhood.||As the tornado approached Somerton Road, it began intensifying |and widening substantially as it moved into the Metropolitan |Industrial Center. Numerous softwood and hardwood trees were |snapped or uprooted in the SUEZ Water Company property southwest |of and along Somerton Road. Five wooden power poles were snapped |near the ground along Somerton Road as well at the northern end of|the SUEZ property. All seven warehouse buildings in the |industrial complex northeast of Somerton Road sustained at least |minor damage, with the most significant occurring to the Northtec |building. Numerous roof mounted HVAC units were shifted or blown |off of a few of the buildings in the industrial complex. Open bay |doors in the western- most building caused a non-load bearing |interior wall to collapse. A sedan was lifted and flipped over in |the Northtec parking lot and a steel flag pole bearing a flag |flattened completely to the ground. The Northtec building |sustained substantial structural damage where large sections of |roofing material were removed. Additionally, numerous exterior |paneling was blown off, garage bay doors were blown out, a few |windows were blown out, and at least two large HVAC units were |blown off of the building. Numerous softwood and hardwood trees |were uprooted or snapped in the industrial complex and immediately|adjacent areas.||A cellphone tower adjacent to the industrial complex had all of |the antennas blown off, but the tower itself did not collapse. |Southeast of the industrial complex, minor cosmetic damage |occurred to some homes along Carter Road in a residential |neighborhood. Tree damage associated with the tornado occurred |along Carter Road and Sussex Road north of Buckfield Terrace. This|was the area where the tornado circulation reached its widest |extent of around three tenths of a mile. As the tornado neared and|crossed the Pennsylvania Turnpike (I- 276), an overhead roadway |information sign was blown off and a portion of it landed |downstream nearly a half mile away. Just north of the turnpike, |minor cosmetic damage occurred to a hotel building where a tree |was also uprooted in the parking lot. A large billboard was blown |over just north of the turnpike and south of Street Road. A small |utility building nearby had its roof blown off. The northern- most|extent of the damage occurred on the Toscana 52 restaurant |property where the tornado blew down some chain link fencing and |uprooted a few small trees in the parking lot.||The tornado continued east-northeastward across Street Road |toward the Faulkner car dealership complex where it began |intensifying and somewhat narrowing its path of damage. The four |dealership showrooms sustained significant damage where most |windows were blown out and at least some roofing material was |blown off. The most significant damage occurred to the Buick/GMC |showroom where most of the roofing material was blown off, all |windows and doors were blown out, and exterior walls exhibited |fracturing due to stress from the wind. Roof HVAC units of this |building were tossed into the parking lot behind the building. All|of the dealership signs near the main road were destroyed. Scores|of new and used vehicles sustained significant damage from flying|debris or from being pushed or tossed trough the air.||The tornado continued toward the dealership's main service garage|where the most significant damage occurred. The southwestern |portion of the building was destroyed with most exterior walls |collapsing completely and all roofing material blown off. Interior|walls mostly remained standing. Roof HVAC units were tossed off |of the building with one unit landing nearly 200 yards downstream |of the building. Damage sustained to the building decreased |somewhat toward the eastern end of it where portions of the |exterior walls were damaged and almost all garage bay doors were |blown out. The wind rushing through the garage area carried |debris, car parts, and tools well away from the structure |downstream. Some vehicles near the main garage building were |completely destroyed from large pieces of flying debris or from |being tossed and dropped back onto the ground. A small pickup |truck was crushed from a collapsed exterior wall. Five people |reportedly sustained minor injuries at the dealership complex.||The tornado continued east-northeast toward the Weisser Homes |mobile home park and into an area of trees which sustained |significant damage. Most tree canopies and limbs were completely |stripped from the still standing or snapped trunks of hardwood |trees in this area. A large storage container filled with car |parts from the service garage parking lot upstream was lofted into|the air and dropped into this area of trees. An uninhabited |mobile home model was lifted and completely destroyed at the |mobile home park. Another double-wide mobile home had a large |portion of its roof blown off. Several other mobile home sustained|varying degrees of damage as well. A large amount of various |debris from the dealership complex landed in this mobile home |park. Numerous softwood and hardwood trees near and just |downstream of this area were snapped or uprooted along Old Lincoln|Highway.||At this stage, the tornado damage path narrowed considerably and |intensity weakened significantly as it crossed Old Lincoln Highway|and moved toward the Lowe's and Walmart shopping centers on Route|1. The tornado passed over these shopping centers, but no |structural damage was noted to these structures. Numerous small |trees were snapped and uprooted in the large parking lot area and |line of trees just north of the Bensalem turnpike interchange. |Some exit ramp signs were blown down in the interchange area.||The tornado damage became somewhat discontinuous as it continued |east-southeast into Bensalem across Route 1 and toward a |residential neighborhood. Several homes in the neighborhood |sustained loss of some roofing material and other cosmetic damage |in addition to some tree damage. The tornado continued across |Rockhill Road and along Richlieu Road toward the Christian Life |Center where several trees were snapped or uprooted. The church's |steeple had some paneling blown off, but the steeple itself was |not damaged otherwise. The tornado continued weakening as it |crossed Galloway Road then dissipated in the Bensalem Township |Community Park where some minor tree damage occurred.||No known serious injuries or fatalities occurred from this |tornado. A brief tornado occurred in the Bustleton section of Northeast |Philadelphia. Damage was first observed near Grant Ave at the |Grant Gardens apartment complex, where some minor loss of roofing|material was noted and debris was tossed in a chaotic manner |consistent with tornadic winds. The tornado moved east-southeast |across Roosevelt Blvd. Continued minor structural damage was noted|along a narrow path, mainly consisting of sporadic losses of |siding and insulation. Minor tree damage was also noted. One |building also had ceiling tiles pulled downward with insulation |removed in a car park area, a strong indicator of tornadic |pressure gradient forces. Near Blue Glass Rd, a couple of slightly|larger trees had their trunks snapped, and winds of around 80 mph|likely occurred in that area. The damage path ended near there, |however, after a track length of only around half a mile. Radar |data indicates this was an anticyclonic tornado.
