This series of pictures was sent to me by Roger Smith of Hillsboro,
Oregon on April 30, 2005.  He got them from someone else.  If you are
the original photographer or know who that person may be, please
contact me at jh@oobleck.astro.cornell.edu.

The photos depict the development of several storms, including
tornadoes, over the great plains.
