EF1 Tornado — Oneida, New York

2025-06-22 · near Lairdsville, Oneida, New York

Event narrative

A pre-dawn line of severe thunderstorms dropped south across the county. Rotation occurred in a kink in the line of storms, generating an EF1 tornado from just south of Westmoreland, through the western edge of the Hamilton College Campus, to near

Clinton. Numerous trees were uprooted or snapped, and a farm sustained significant damage to its silo and outbuildings. Debris from the farm was lofted at least 1000 feet across the field, with some of it impaling the ground as debris missiles. While there was this focused corridor of convergent enhanced EF1 tornado damage, other scattered tree damage could be found throughout the area associated with damaging winds up to 70 mph from the line of severe storms.

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.
