Storm Data Entry

McClain

This tornado developed just north of State Highway 9 and just west of Santa Fe Avenue where tree damage was noted. The tornado moved east damaging a business and destroying a shed along Highway 9. The tornado turned southeast crossing Highway 9 and passed near the Riverwind Casino and Hotel along with strong winds on the south flank of the tornado. Trees were snapped just west of the casino. At the casino, two air conditioner units were displaced from their pedestal on the roof of the building, which allowed rain inside the structure. Some roof facade damage was also noted at the casino. Just south at the adjacent hotel, strong winds created some roof facade and siding damage (see adjacent Thunderstorm Wind Entry).

The tornado crossed Interstate 35 and damaged businesses and destroyed at least one shed between the interstate and the Canadian River before moving into inaccessible areas near the river and crossing into Cleveland County south of Norman.

Cleveland

The tornado moved into Cleveland County in inaccessible areas along the Canadian River and generally remained south of the neighborhoods in south Norman south of Highway 9. Some tree and fence damage was observed at the southern end of South Canadian Trails which is where the tornado is believed to have dissipated.
