An F1 tornado with maximum winds estimated at around 90 MPH briefly touched down and knocked out a 55 foot wide by 30 foot high hole in the southeast corner of a cinder block warehouse. Several witnesses reported seeing the tornado lift back into the cloud just after it knocked out the wall. Cinder blocks were blown out roughly 25 to 30 feet to the east from the building. The cell continued moving to the southeast with no other damage reported.
