Low pressure over the Ohio Valley moved northeast and brought a strong cold front to the region. The thunderstorms that accompanied the cold front produced damaging winds which downed trees and power lines in Busti and Hinsdale in the southern tier and in Port Byron and Watson in the north central portions of the region.
The west to southwest winds following the cold front increased to 25 to 35 mph with gusts up to 70 mph. The strong winds downed trees and power lines. Between fifty and seventy-five thousand customers were without power across the region. In Lockport, the roof blew off of the Niagara County Parks and Recreation Office. Falling trees damaged homes in Salamanca, Niagara Falls, Cheektowaga, and Williamsville.
Along the Lake Erie Shore, the water levels at the eastern end of the lake fell several feet ahead of the storm, then quickly surged as the winds shifted with the passage of the cold front. The lake level rose over ten-and-a-half feet in a matter of hours, peaking at 9.93 feet at the lake level gage at Buffalo. The high winds and waves made for treacherous driving conditions along the Lake Erie shore roads and resulted in minor flooding along the Niagara River.
Specific high wind gusts recorded by ASOS and Schoolnet sites included: 69 mph at Buffalo (downtown); 67 mph at Buffalo (Airport); 65 mph at Hamburg; 62 mph at Lackawanna; 59 mph at Alfred; 58 mph at Elma; 55 mph at Watertown Airport; 52 mph at Rochester Airport; and 50 mph at Fulton Airport.
