What happened

The episode as NWS BGM wrote it up.

A strong low pressure system tracked northeast from Kentucky to western New York state during the daylight hours on Thursday the 16th. A large fetch of Gulf and Atlantic moisture was pulled northward ahead of the cold front, which produced a squall line of thunderstorms with very heavy rainfall. This line of thunderstorms produced 45 to 74 mph winds across a large part of central NY. Additionally, the squall line spawned an F1 tornado north of Elmira, NY. As the squall line moved east, late in the afternoon of the 16th, it slowed down and stalled for a time. Areas from Owego and Binghamton, NY, north and east through Ithaca, Cortland and Norwich, NY, to Oneida county in the western Mohawk Valley and the northern Catskills saw the brunt of the heavy rainfall from this slow moving line of storms. 1.5 to 4 inches of rain fell in just 3 hours causing significant flash flooding over many of these areas. Many hillsides and creeks turned into raging torrents, causing mudslides and debris flows that cascaded into more populated valley areas. In the urban valley regions, the flash flood reports were numerous with road washouts, highway closings, and some parking lots that were entirely flooded, ruining many cars. A mudslide on Interstate 88 outside of Port Crane, NY caused a multi-car pile up. The flash flooding evolved into a minor to moderate river flood event mainly on the Susquehanna River and its tributaries in New York from Thursday night the 16th until Saturday the 18th.
