What happened

The episode as NWS BGM wrote it up.

A front from southern New England to near Washington D.C Sunday morning the 25th moved slowly west, to a position from just north of New England, south-southwest across the Adirondacks through central New York and then down the spine of the Appalachians by Monday morning the 26th. Tropical moisture moved westward and engulfed nearly all of New York State and most of northern and eastern Pennsylvania by Monday morning. This resulted in a widespread area of moderate to heavy rain across all of central New York and northeast Pennsylvania including the Poconos and Catskills by Monday morning the 26th. The heaviest rain occurred in the Poconos and Catskills where rainfall amounts totaled between 1.5 and 4 inches by 8 am EDT Monday. In Sullivan County, 2 to 4 inches of rain fell by Monday morning, which saturated soils. Another round of heavy rain showers and thunderstorms moved back into the northern part of the county during the day Monday the 26th. This additional heavy rainfall caused flash flooding in Youngsville closing Route 52. There were many streams overflowing their banks in and around Youngsville Monday afternoon and evening.
