After a week of late summer warmth and humidity, a cold front crossed the region. The front sparked showers and thunderstorms with its passage. Several of the thunderstorms produced large hail and damaging winds with the large hail mainly across the southern tier and the damaging wind gusts across the north country.  Hail, up to 1.75 inch in diameter, was reported in Jamestown, Bemus Point, Lakewood, Jordan, Red Creek, Marion and Oswego. The thunderstorms winds downed trees and power lines. At the Chautauqua Lake Yacht Club in Lakewood, several boats were flipped in addition to the down limbs and wires. In several locations, downed trees made roads impassable.
