Event narrative (NOAA)
An isolated supercell thunderstorm developed a tornado three to four miles west of Highway 30. The tornado continued an eastward track and intensified rapidly over the mainly open fields. Numerous wooden power poles were snapped along County Road 121, along with several galvanized steel utility poles, which were bent 90 degrees at the base. Grass was scoured out of the ground in a wide swath approximately one third of a mile in width near the intersection of County Road 121 and Cattle drive. The observed tornado continued east into the Laramie Range near King Mountain Road.
