Eighty mph winds toppled four trees southwest of Henry.
High pressure over the Atlantic provided an easterly flow which pumped in plenty of moisture from the ocean. An upper-level low remained nearly stationary over the region, triggering showers and thunderstorms. With light winds aloft showers and thunderstorms were slow to move. Showers and thunderstorms produced locally heavy amounts of rain in a short period of time and this lead to an isolated flash flood event in northern Virginia.
