What happened
The episode as NWS BGM wrote it up.
An upper level atmospheric disturbance moved out of the Ohio Valley and produced scattered lines of thunderstorms from western New York into Pennsylvania during the evening. A severe thunderstorm developed on the southern edge of one of these lines of showers that was moving through north central Pennsylvania. This storm began rotating shortly after it developed north of Williamsport and dropped a tornado over northeast Lycoming county. The tornado then tracked northeast through Sullivan and into Bradford county shortly before 8 pm EDT. This weak tornado uprooted several dozen large trees and some powerlines in Overton Township as it moved over the ridgetops. Trees blocked county roads for several hours stranding some neighborhoods until the following morning. On Cahill Road, trees smashed into an unoccupied summer cabin, causing minor damage to the roof and a back porch.
