(Rozet Wyoming) Video shot by Rozet resident Tiffany Humes, shows a possible tornado west of town on Sunday. This is possibly the storm that caused the damage in the Freedom Hills area of Gillette on Sunday evening. The video shows what appears to be a twister moving northeast. No word from the National Weather Service that would confirm this as a tornado, or on the strength of the storm.
EDIT: Confirmation now from NOAA and The National Weather Service out of Rapid City SD, that the storm was indeed a tornado.
