A fast moving upper level shortwave passed through the area during the afternoon hours on Friday, June 30th, 2017. With a warm and muggy air mass in place, this shortwave sparked off numerous strong to severe thunderstorms, especially across the Mohawk Valley, Saratoga Region and Capital Region. The severe storms produced two EF-1 tornadoes in Fulton and Herkimer counties, as well as knocked down numerous trees and power lines across the region. There was also one report of large hail in Saratoga county.  One of the storms also caused four injuries in Schodack, where a fireworks display tent collapsed due to thunderstorm winds.  At least 1500 people lost power as a result of the thunderstorms.
