Where the report was made, with tornadoes recorded within 15 miles over the years.

The wider storm

An upper-level low sagging down the Oregon Coastline was responsible for drawing moist, unstable air into its northwestern flank and ultimately across the lower Columbia Basin. A combination of surface heating and shortwave energy ejecting from the low triggered strong thunderstorms over northern Oregon which tracked through the lower Columbia Basin during the evening of July 19th. A thunderstorm that tracked over Royal City around 1800 PDT produced a brief funnel cloud.

Began near Royal City (46.8391, -119.5401).
