What the National Weather Service wrote

Public reports about 10 miles south of Pendleton, OR reported a thunderstorm that was producing hail between the sizes of 1 inch to 1.25 inches between 1700 PST and 1730 PST.

The wider storm

A potent upper level shortwave trough coupled with a cold front passage at the surface provided showery activity through most of the day. During the afternoon, these systems interacted with increasing instability, strong bulk shear, and upsloping into mountain areas allowed some of these showers to strengthen into strong thunderstorms that produced severe hail and a tornado.

Began near Sparks (45.5400, -118.8200).
