EF1 tornado in Chemung County, New York

A tornado touched down and moved up and down over ridges and valleys for almost 14 miles. The first touch down was across Route 1 in North Chemung. The tornado moved east, eventually moving out of Chemung County into Tioga county just northwest of the Town of Lockwood. The majority of damage was to softwood and hardwood trees which were uprooted or snapped. Unlike the extensive straight-line wind damage found to the south of this track, this damage clearly had signs of circular motion in a very concentrated and narrow path. The damage path averaged about 200 yards wide. Some homes, garages and sheds were damaged by wind with trim or siding torn or shingles off roofs. Some homes had more significant damage from trees falling on them. One barn was completely destroyed.

On the afternoon of July 26th, a significant severe weather event impacted portions of the Binghamton, NY forecast area. By the late morning/early afternoon, a warm front had lifted north through the region placing much of the Binghamton forecast area in a moderately unstable airmass. Aloft, multiple approaching upper-level shortwave troughs approached the region from the central Great Lakes during the early afternoon hours which provided the initial forcing for thunderstorm development. Also, a punch of mid-level dry air helped create mid-level convective instability along with a favorable setup for strong damaging winds.
