Overview
After widespread morning clouds and fog on Tuesday, September 19th, 2017, there were some questions as to when and where late afternoon and evening severe thunderstorms would form. As a frontal boundary moved into the Devils Lake to Jamestown corridor by late afternoon, storms began to form. These storms moved slowly eastward through the evening, producing isolated tornadoes, large hail, and strong winds. These storms weakened during the early morning hours of Wednesday, September 20th.Tornadoes:
