Wider weather episode
A surface low was east of the area with two associated surface boundaries draped across the area. By late afternoon the two boundaries began to merge with thunderstorm development in central to northern Iowa. Instability was modest, but concentrated in the lower three km of the atmosphere, which allowed for enough stretching to support a brief tornado.
