What the reports say
Written by National Weather Service staff at the time of the event · public domain
This tornado that was well documented by a storm chaser, was visibly much stronger than the damage that was done. A couple of irrigation sprinklers were damaged but had the tornado encountered trees or buildings, it appears the damage could had been at least EF3. The tornado initially moved south/southwest, then curved south and finally southeast and east before dissipating. For July this was a significant tornado and supercell thunderstorm.
