Episode Narrative The combination of an unstable atmosphere and converging wind boundaries over Lincoln County spawned four tornadoes, as well as large hail and flash flooding. This activity spread into northern Whitman County as well. The tornadoes were observed in a 25 minute period between Wilbur and Creston near Highway 2. All four tornadoes were non-supercell tornadoes and rated EF0. All four tornadoes remained over wheat fields and thus resulted in no property damage. Meanwhile, a severe thunderstorm produced quarter sized hail three miles west-southwest of Sprague. Heavy rain also fell with the storms over Lincoln and northern Whitman County. On Highway 23, about five miles northwest of Sprague, water covered portions of the highway between mile posts 48 and 53. In northern Whitman County, mud and debris washed onto roads near Ewen, Colfax, and St. John.
