Episode Narrative A pre-frontal trough caused scattered severe thunderstorms to develop across Southeast New York, including a tornado in Orange County. Some of the storms produced very heavy rain which led to flash flooding in New York City.
Event Narrative Based on a damage survey conducted by the NWS Mount Holly New Jersey Office in conjunction with the Orange County Office of Emergency Management, along with evidence from Doppler Weather Radar and photographs, it was confirmed that an EF0 tornado struck Unionville. Dozens of trees and a multitude of large tree branches fell across streets, and upon several houses and cars. This tornado was produced by the same severe thunderstorm that produced an EF2 tornado in Wantage New Jersey just minutes earlier during the afternoon on July 29th.
