An automated weather station on the far west side of Powell recorded a peak thunderstorm wind gust of 58.3 mph at 1708MST. The wind dropped a tree on North Douglas Street in Powell and stopped traffic for 30 minutes. Seven other toppled trees in an older section of town blocked streets for approximately three hours until city crews could clear the debris using chainsaws.
Nearly an inch of rain and a large amount of large hail fell in only 20 minutes around Powell, Wyoming. The result were numerous areas that were flooded, including streets, businesses and homes. The main damage was from water in basements and flooded roads.
This tornado formed 5 miles east/southeast of Powell and tracked eastward for 3.5 miles before exiting Park County about 8.5 miles east/southeast of Powell. This tornado continued in Big Horn County for another half mile, before dissipating at 1231 MST. This tornado formed over open country without damage, therefore it was rated as F0.
