Thunderstorm Wind — Delaware, New York

2025-06-22 · near Youngs, Delaware, New York

Event narrative

Strong thunderstorm winds knocked down multiple trees and wires on NY 357 which closed all lanes.

Wider weather episode

A mesoscale convective system (MCS) dropped southward across Central NY from eastern Ontario, moving into an environment with plenty of moisture and instability during the early morning hours. This complex of thunderstorms started to bow out and produced widespread damaging wind gusts and heavy rain. A couple of small kinks along the leading edge of the line of storms did result in two EF-1 tornadoes spinning up before daybreak in Oneida County. Unfortunately one of the tornadoes resulted in 3 fatalities in Clark Mills, NY.
