What the National Weather Service wrote

On July 17, 2013, a multicellular thunderstorm developed a gustnado causing a roof to be torn off of a closed garage and thrown into a power pole. The power pole broke off leaving live wires on the ground. Another shed immediately downstream was torn apart and thrown across the yard. The path of the damage was about 200 yards long and 50 to 100 feet wide. A neighbor watching the event occur from a few feet away, reported swirling debris for at least 10 to 15 seconds.

The wider storm

A mid-level southwest 50 knot jet maximum combined with high moisture and very warm temperatures provided the prime environment for strong supercells. These cells brought both severe wind and hail.

Began near West Vly (46.1540, -113.0220).
