Based on multiple storm chaser videos, ground contact was evident most of the way, but not always, as there were two or three occasions when ground circulation was not evident for one or two minutes. But some storm chaser video showed it to be entirely from the same parent circulation, hence one tornado. The tornado hit several farms. At one farm, both garage doors on either side of a house were buckled in, multiple trees were snapped or large branches broken. Two farm outbuildings had their garage doors blown out. Some shingles were also removed. Dozens of trees nearby were blown over. A small trailer was blown over 100 yards. Another farm had two small outbuildings that were destroyed and trees down or broken. The maximum wind speed was estimated at 90 mph.
