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.

A supercell thunderstorm moved into southern Luzerne county at approximately 5:05 PM EDT from east-central Columbia county. As the storm entered the county, doppler radar indicated a tight cyclonic circulation contained within the storm's mid-levels. As the storm traveled east, numerous trees were downed or uprooted just south of Sybertsville in the township of Sugerloaf. Reports from local Emergency Management Officials indicate that all tree damage in this location was oriented in the same direction, consistent with straight line wind damage. As the storm traveled east, extensive tree damage occurred in Butler Township along east Foothills Drive, immediately east of Route 309. Again, downed trees were oriented all in the same direction, consistent with straight line wind damage with winds estimated between 90-100 mph. The storm then continued east where extensive damage occurred along main street just south of Freeland in western Foster Township. At this location, an outside storage building was destroyed. Debris from the building then traveled through the air and penetrated in several locations the roof of a 58 foot tall building. After hitting and destroying the building, additional damage occurred directly to the northeast where several trees were downed or uprooted. Downed trees were convergent in nature, consistent with a tornadic circulation moving over the area.
