Thunderstorms that developed in an unstable air mass during the afternoon hours were enhanced by lake breezes. A thunderstorm over Chautauqua County produced downburst winds estimated near 60 mph that downed trees and power lines in Findley Lake. The heavy rain that accompanied the storm resulted in flash flooding. Route 426 was closed due to flooding. Elsewhere, thunderstorms produced hail up to one inch in Niagara Falls, Niagara County and just outside of North Osceola, Lewis County.
