| Brief Description: A warm frontal boundary interacted with a complex of showers and thunderstorms to form a tornado on the southern flank of the precipitation. Touchdown was along Adamsville Road near Route 35. The roof was ripped off a home, 2 mobile homes were destroyed, along with a pole barn. The tornado then struck both rest areas on Route 35. The rest building on the north side of the highway was severely damaged. At least 2 tractor trailers were flipped over, while others parked in the lot, were damaged. Another mobile home near the rest stop was destroyed. Proceeding just east to Dewey Road, the tornado wiped a modular home off its foundation. A trailer was destroyed at the corner of Kerr and Viney Roads. Down Kerr Road, a home had its roof removed and a mobile home was moved off its foundation.
