All this information will change as it becomes available. Here in Midwest City, OK, we had winds of 70-80 miles per hour with hail varying from pea sized to golf ball sized hail. Some minor damage to vegatation was noted as well as a few dents in cars due to the hail.

I have decided to add a sixth tornado per further investigation above on Friday, May 27, 2011. Also, wind speeds were added to the 3rd, 4th and 5th tornadoes as the surveys are becoming finalized. On June 10, 2011, I had added information on five more tornadoes, here numbered 7, 8, 9, 10 and 11 on this. I adjusted the path length of the second tornado. At first tornadoes 7 and 2 were thought to be one tornado, but later surveys shown it to be 2 tornadoes, not one.

  1. I was happy to find this info here. I am a survivor of Tornado two. Our area was northwest of Peidmont-or actually S.E. of Cashion. It wiped out our whole neighborhood and even killed some people. Its still shocking how powerful that tornado was

    1. I still can’t believe the damage that tornado did. A high school in Guthrie, where a nephew of mine graduated, was wiped out. A friend of mine from Piedmont lived about a mile from where it passed near there. I am glad that you made it through. And I agree with you wholeheartedly, still shocking to know how powerful that storm was. I am glad you made it through and hope the road to recovery is a quick one!
