A surface cold front and very strong mid-level disturbance moved across a highly unstable air mass across all of New York during the late afternoon and evening of July 8th. The low level jet stream was unusually strong and got entrained into the thunderstorms, thus producing scattered to widespread wind damage across Northern New York, especially St. Lawrence county. Much of the wind damage was tree and utility line damage but also some structural damage due to fallen trees. Some wind damage was estimated at 70 mph or greater.
