These images are of the funnel that dipped in and out of the wall cloud.      These images have only been darkened for definition sake.      These images are looking north at Cedar Bluffs NE, 1 mile south.      Note how close to the grain elevator the funnel is, i.e. height from ground.      Upon closer inspection of the first image here and our chase video, small amounts of dirt appear to be lifting into the air revealing a faint tornado.      Story Page      Wall Clouds
