Event narrative: Based on a tornado debris signature from the KEOX radar, a tornado touched down in a remote area near Barnes Creek south of CR 36. The tornado then tracked northeast, damaging several metal chicken coops on CR 36. The tornado next snapped a couple of trees on North CR 55. After crossing Oamon Pond Road, the tornado turned slightly to the right, snapping trees and significantly damaging an outbuilding on Childs Road. The largest concentration of damage occurred in a wooded area just southwest of CR 47 where numerous hardwood trees were snapped or uprooted. This is where the tornado reached its peak intensity of 105 mph, leaving a trail of debris across adjacent fields. The tornado then did significant damage to a barn on CR 57 where several smaller trees were also snapped. The tornado may then have briefly lifted before doing some damage on North CR 69. While debris signatures were still evident on radar, no damage was noted downstream from this point. Damage along most of the path was consistent with EF-1 damage.
Episode narrative: A mid-level shortwave trough moved across the northern Great Lakes with a belt of stronger flow moving through the southern Great Lakes.

Event narrative: The National Weather Service in Pittsburgh conducted a storm survey and concluded the damage was consistent with an EF-1 tornado.  Tornado damage began along Valley View Road in East Finley township.  An intermittent, and extremely narrow damage path continued along  Cracraft Road where an attached patio roof was taken off along with  part of the roof to the main residence. Additional snapped  or uprooted trees were observed further east along the  street at a neighboring residense. The most significant damage  occurred just past the midpoint of the tornado track, along the west  side of PA Route 221 where a cluster of approximately 30 pine trees  were all snapped near the base up to approximately 1/3rd of the way  up the trees, consistent with a high end EF1 rating. Additional  damage was noted along PA 18 to a township shed and outbuilding.  This was the end of the observed damage track, with beginning and  end concident with a well-defined gate-to-gate velocity couplet and  hook echo present from the Pittsburgh Doppler Radar. Length and  times of this tornado have been updated based on the additional  damage obtained since yesterday's initial survey. The very narrow  width to this tornado is further supported by video of the event  provided to the National Weather Service via social media.
Episode narrative: Tropical Storm Harold moved west across south Texas on the 22nd. An area of low pressure developed over the central Gulf of Mexico on the 21st.
