One other tornado warning was issued within the area we were in for a comma-head on the north end of a squall line, and we did happen to be in a decent area to try and catch it. At near the same time a tornado was reported near Rolla, Oklahoma, we viewed what appeared to be a wall cloud with the comma head. However, we didn't see anything that resembled a tornado. A few minutes later, we were overtaken by the squall, and we gave up on it and decided to eat dinner at a nearby Pizza Hut.
