The mesocyclone was rather large, even pulling in some of the precipitation from ahead of the storm. As the storm moved farther to the northeast, it nearly destroyed several farms before it plowed into the Luther Marsh, north of Grand Valley. East of the marsh, the storm weakened somewhat and the tornado narrowed in width. Upper-level winds were stretching out the storm causing a larger gap between the precipitation core and the tornado, thus making it even more visible to people in the storm's path. South of the tornado, it was warm, windy, and free of precipitation, with a spectacular view of the storm. The tornado damaged more homes and then crossed Highway 25, taking down several hydro transformers in one very bright power flash. The tornado now had a textbook-style appearance as a narrow wedge.
