What happened

The episode as NWS BGM wrote it up.

Tropical moisture continued to stream northward into eastern Pennsylvania ahead of a frontal system which slowly moved westward into the eastern Great Lakes by Tuesday morning the 27th. This tropical moisture developed a batch of heavy showers and thunderstorms across much of eastern Pennsylvania late Monday evening the 26th through Tuesday morning the 27th. Up to 2 inches of rain fell in the Tunkhannock area by Tuesday. This rain fell on saturated ground from previous rains that occurred Sunday and Monday leading to flash flooding in the Tunkhannock area. Several roads were reported to be washed out Tuesday morning. The rain tapered off for a few hours Tuesday morning allowing the waters to recede temporarily.
