What EF2 means. On the Enhanced Fujita scale, EF2 is considerable damage: roofs torn off well-built houses, mobile homes destroyed, large trees snapped or uprooted, consistent with estimated gusts of 111–135 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

The tornado touched down on county Route 7 in Pharsalia and produced EF1 damage to a few barns and some trees. The tornado traveled northeast approximately 8 miles before dissipating on Pigeon Hill Road in Pharsalia. Intensity for most of the path was estimated at EF1, however EF2 intensity was estimated along North Road and Center Road in Pharsalia. In those areas hundreds of large trees were snapped and uprooted leveling a dense forest. Over the hill a house trailer was lifted and demolished, a two story barn was demolished, a small pond had its water sucked out, and a jeep was moved several feet and hit with debris. Outbuildings were also destroyed.

The wider storm

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.

Began near Pharsalia (42.5510, -75.7730).
