Episode Narrative A deep upper-level trough sagged into the Pacific Northwest during the afternoon of October 5th. Stable rainfall was common through most of the morning and early afternoon over eastern Washington. During the early afternoon, a jet streak rounding the base of the trough coupled with cooling aloft, and brief thinning of the overcast skies on the eastern flank of the precipitation shield contributed to a rapid, very short-lived window of surface based instability and low-level wind shear over the Washington Palouse. This resulted in the development of two intense updrafts and formation of a pair of funnel clouds, one which briefly touched down over open wheat fields in northern Whitman County. There was no damage or injuries related to the tornado.
Event Narrative A farmer in northern Whitman County spotted two funnel clouds the afternoon of October 5th approximately thirteen miles northwest of Saint John. One funnel cloud briefly touched down over open wheat fields.
