The tornado first touched down behind a house on Jurista Hill Road. The first signs of damage were to the top quarter of a pine tree which was twisted and bent over the tree itself. Continuing northeast, one large tree was uprooted with one smaller tree snapped. Another large tree was uprooted, and an 8 foot by 16 foot wooden shed rolled over for 30 yards. More tree branches were broken before the tornado moved toward a corn field, damaging a barn. After minor damage to small areas of the corn field, more trees were snapped and uprooted before the tornado lifted. The tornado passed right next to a two story house, with only a small section of the metal roof showing signs of uplifting.

A NWS storm survey confirmed a tornado touchdown at the Skyhaven Airport. The first signs of damage were to a metal roof which was peeled away from a farm outbuilding. Pieces of this roof were moved in a northeast direction for over 400 yards. There was limited damaged to trees, mainly consisting of small downed branches. Toward the edge of the airport, corn stalks were blown toward the northeast. On the other side of a grove of pine trees, pieces of the metal roof were blown back toward the west and southwest. Pieces of roof ended up toward the emergency operations center, about 1.21 miles from the building from which it was peeled. The tornado continued northeast to the edge of the runway before lifting up.
