The O'Neill, Nebraska tornadic supercell began to develop at 2125 UTC 09 JUN 03 along the NE/SD border. The supercell tracked east/southeast. I viewed three seperate tornadoes from this cell, one of which was near a 1/2 mile wide. Pictures of the tornadoes and damage will follow in the next few weeks.
