EF0 Tornado — Marion, Oregon

2018-10-29 · near Jefferson, Marion, Oregon

Event narrative

There was damage to multiple small shrubby trees just north of the railroad track along Libby Ln. There was also a sign knocked over at the NW corner of Libby Ln and Jefferson-Marion Rd, but whether or not it was caused by a tornado could not be determined. The tornado was likely on the ground for one minute or less.

Wider weather episode

A cold front which moved through on October 27th brought a much cooler air mass in aloft, which destabilized the atmosphere enough for thunderstorm development across the area on the 28th and 29th. There was enough vertical shear in the environment for a few of theses vigorous showers and thunderstorms to start to rotate, three of which went on to produce tornadoes.
