In Middle Tennessee, the National Weather Service on Sunday confirmed an EF-2 tornado with maximum winds of 120 mph (193 kph) hit Clarksville on Saturday.

Montgomery County Sheriff's Office spokeswoman Sandra Brandon said at least four homes were destroyed and dozens of others were damaged, while 75 cars at a tire plant parking lot had their windows blown out or were tossed onto one other.

"To look at what I'm looking at and know we didn't lose anybody is just a miracle," Montgomery County Mayor Jim Durrett told The Leaf-Chronicle.

At Austin Peay State University in Clarksville, a teenage girl was hit by falling debris at a college basketball game after an apparent lightning strike knocked a hole in the arena's roof Saturday night. School director of marketing and digital media Kevin Young said the 15-year-old girl was taken to a hospital as a precaution. The extent of her injuries weren't immediately released.

The game between Austin Peay and Murray State was stopped with 5:49 left in the second half due to the leaky roof. Fans took shelter in nearby hallways and athletic offices before play resumed after a more than three hour delay.

Austin Peay President Alisa R. White said on Twitter that athletics department officials and physical plant workers "did a great job handling a big crowd and the elements in what could have been a much worse situation."Clarksville is about 48 miles (77 kilometers) northwest of Nashville, Tennessee.
