Several bands of strong to severe thunderstorms developed along two north-south axes of low level confluence across central Pennsylvania into upstate New York. The storms produced large hail, damaging winds and intense short-duration rainfall from the mid afternoon hours through the late evening. The combination of the heavy rain, above normal soil moisture and high stream-flows resulted in significant localized flash flooding in Sullivan County which lasted into the overnight hours.
