What the National Weather Service wrote

As a right-moving supercell approached the Eureka airport, it unleashed severe downdraft winds as reported by the AWOS sensor from the southwest direction for at least 12 minutes. The observer at the airport reported that one airplane flipped over, steel siding was torn off from a hanger, a telephone booth blew over, and an awning structure blew off.

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 Roosville (48.9671, -115.0810).
