A surface trough developing in a hot and humid airmass ahead of an approaching cold front resulted in the development of widely scattered showers and thunderstorms on the afternoon of August 7th. By evening, these showers and storms merged over New York City and Long Island, resulting in isolated reports of flash flooding. Rainfall totals ranged from around one inch in parts of New York City to 1-3 inches across much of Nassau and western Suffolk County.
