A powerful low pressure system formed on May 4th, pushing a strong cold front across eastern New York. A line of thunderstorms developed along this front in the afternoon and evening, resulting in widespread wind damage. Nearly 60,000 customers lost power as a result of the storms. Particularly intense damage occurred in the villages of Johnstown and Cambridge, the town of Hebron, and Saratoga National Historical Park, where dozens of trees were uprooted and snapped in concentrated swaths. Some of these trees fell onto cars and houses, resulting in property damage. The National Guard was deployed to assist with storm recovery in Washington County.
In the evening hours, strong non-thunderstorm winds developed behind the cold front, impacting portions of the southern Adirondacks. Winds gusted as high as 58 mph at Chestertown, and a few trees and limbs were downed.
