EF1 tornado in Chenango County, New York

A tornado path began about 3 miles to the northwest of Columbus, NY off Barnard Road. Damage was primarily to trees which were uprooted and snapped. The upper story of a two story horse barn was torn off. This was the only structure identified that was damaged by the tornado. Debris and trees were blown to the left of the path. The remaining damage was to trees along the 0.9 mile path. The tornado weakened to EF0 after the first mile then strengthened back briefly to EF1 after crossing Kelly Road. The tornado then weakened again to EF0 and lifted after crossing Pope Hill Road before reaching the Madison county line.

A significant severe weather outbreak developed across central New York as a storm system moved east from the Great Lakes. First, showers and thunderstorms developed early in the evening on the 27th, as an upper level disturbance approached the region. Two of the more significant storms included one supercell that produced a tornado in Steuben county, and a bowing line segment that caused tree and structural damage across Steuben, Chemung and Schuyler counties. Elsewhere across central New York, storms caused scattered wind damage and heavy rain.

After a brief break in the late evening, mini super cells developed overnight ahead of a cold front. Several tornadoes and severe thunderstorms developed between about 1:30 a.m. and 6 a.m., with many reports of damage. Most of the tornadoes were EF1 and EF2. Significant flash flooding also transpired during the overnight hours.
