Overview

On December 14, a cold low pressure trough over the Pacific Northwest generated showers and thunderstorms over the Portland CWA. A short wave (thought to be a gravity wave generated by a small offshore low that developed in the cold pool behind the main front) rotating through the trough increased convection southeast of Salem, OR shortly before noon. At 11:53 AM, a Severe Thunderstorm Warning was issued based on 88D radar signature combined with a report from the public of some downed trees. At 11:59 PM, the WFO received a report of a tornado touching down from the same convective cell and a Tornado warning was issued at 12:02 PM.
