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.

After a nearly continuous path of straight-line wind damage across southwest and south-central Broome county, a survey team confirmed a tornado touch down just east of Interstate 81 in the town of Kirkwood.  The tornado path began on Burts Road, approximately 0.62 miles north-northwest of the Burts/Gorman Road intersection.  At this location, multiple hard and soft wood trees were snapped or uprooted.  Many fallen trees were oriented in a convergent pattern, which is consistent with tornadic damage.  The tornado path continued in a south-southeast manner before lifting.

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.

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.

Thunderstorm Wind in TIOGA, NEW YORK

Location: BARTON
Magnitude: 87.00 EG
Property damage: 25.00K
Crop damage: 0.00K
Reported by: NWS Storm Survey

Intense straight line or microburst winds from a thunderstorm struck just west of Route 34 about 4 miles north of the village of Waverly around 414 PM EDT. The high winds took part of the roof off an open pole barn near Route 34 and knocked down and snapped many trees and tree branches along its path to the east northeast toward north Barton. The winds were mainly between 60 and 80 mph, except on Madigan Road where maximum estimated winds were around 100 mph. Numerous large pine trees and a few hardwoods were snapped and a well constructed relatively new horse barn had its roof lifted off and thrown up to 150 yards downwind. The owner of the barn was inside the structure when the roof was lifted off and had both doors barred shut. The winds hit the barn on the side with no windows. It should be noted that the barn was made of metal siding as was the roof. The winds were strong enough to blow the doors out on the sides of the barn and tear the roof off, making it likely that winds were around 100 mph. The winds then continued up the hill to the east and weakened.
The total path length of the microburst wind damage was about 2.5 miles and the width of the damage was around 2 miles wide.
