 Brief Description: A storm spawning two separate tornadoes passed over southern Armstrong County, continuing eastward into Indiana County. The first tornado, an F0, touched down at approximately 2:45 PM EST just south of the town of Spring Church in Armstrong County. It traveled east about 3 miles before crossing into Indiana County approximately 1 mile east of Maysville at 2:52 PM EST. This tornado continued traveling to the east for another mile, finally dissipating near the community of Iselin at around 2:55 PM EST. The maximum estimated winds with this tornado were about 70 MPH. Damage from this first tornado included numerous trees which were toppled or snapped. A small steeple was toppled, and a swimming pool was destroyed. There were several trees toppled onto houses, and some houses suffered minor wind damage. A garage was damaged, and a house under construction was lifted off the foundation. The same storm produced another stronger tornado, an F2, which touched down in Indiana County approximately 6 miles southwest of the city of Indiana at 3:00 PM EST. This F2 traveled to the east across Center Township for approximately 5 miles, dissipating just south of Indiana at 3:06 PM EST. The estimated maximum winds were around 135 MPH. This F2 tornado produced a swath of damage as it traveled eastward across Indiana County. One house was totally destroyed, and debris from this house was blown downwind. In this same area, a car was turned over and trees were stripped of leaves. An adjacent house exhibited damage from hail or flying projectiles on several sides. The house immediately to the north of the destroyed house lost part of its east-facing roof. There were at least an additional 18 houses damaged (roofs, shingles, siding, etc.). Several garages and barns were either toppled or snapped. A large sign from a hotel was blown down onto a car sales lot. Two cars were crushed and 18 other vehicles were damaged. One moderate injury was reported with this tornado.

 Brief Description: A tornado touched down in Jefferson County and traveled southeast into northeast Indiana County, the tornado continued into the State Game Lands and exited Indiana County 4 miles north-north east of Glen Campbell and then entered Clearfield County. The tornado's path was 200 feet wide at its greatest width in Indiana County. Just some tree damage occurred in Jefferson County. The tornado strengthened and caused greater damage in Indiana County. Just east of Rossiter, the tornado tore the roof off of a barn. A child, playing outside, sought shelter in the barn. The roof lifted off and three of the four walls collapsed. The child was not injured. A horse that was inside the barn was sucked out and carried approximately 75 feet in the air into a field. The tornado traveled then traveled up a hill and significantly damaged one mobile home and destroyed a second. The second mobile home was carried at least 75 yards across a road and smashed against a row of trees. Three people were inside the mobile home and were injured, one critically. The tornado at this time was at it's strongest, at the upper end of F2. A nearby wood frame house was destroyed and dense areas of trees were felled or snapped. About a dozen homes sustained damage along the path, 5 were damaged extensively. Thirty pound cinder blocks from a garage were thrown approximately 300 yards up a nearby hill where a stronger suction vortex was noted. The tornado tracked into the State Game Lands and a 50 yard path of downed and twisted 100 to 150 foot trees was noted into the densely forested region.

 Brief Description: A severe thunderstorm produced a tornado that produced substantial damage in a residential area east-northeast of Latrobe along the foothills of the Chestnut Ridge. The tornado first touched down 1 mile west of Derry. The tornado completely destroyed a large tier of metal stadium bleachers at a high school football field and wrapped them against a utility pole. A nearby roof of a business was damaged and a mobile home was completely destroyed and a few mobile homes sustained damage. The tornado then tracked through a rural area, damaging some farm buildings and downing field corn. The tornado continued its rapid (estimated forward speed 50-60 miles per hour) northeast track and caused significant damage in a mobile home park in Derry. The tornado crossed Route 217 and downed trees across railroad tracks and then entered a residential area in Millwood. One frame house in Millwood was severely damaged and part of a room addition collapsed and trapped a resident, who was treated at the scene. A resident of a mobile home sustained minor injuries as well. Numerous trees were uprooted and large branches and power lines were downed along the track of the storm. One home along Route 217 had a branch embedded into the house siding. The tornado was estimated to have wind speeds of between 90 and 120 miles per hour, briefly attaining an F-2 rating on the Fujita Tornado Scale. All tolled, 7-8 mobile homes were destroyed (3 totally decimated), 10-12 sustained major damage, 15-18 sustained minor damage. One frame house was heavily damaged and about 10 sustained minor damage. One car was destroyed when a tree fell on it. Parked next to the auto was another car with two occupants that were not injured. About 10 other cars were damaged. An open-air church in Millwood was also heavily damaged. The tornado appeared to have dissipated as it entered the heavily wooded slopes of the Chestnut Ridge.
