| Episode Narrative | Clearing skies in the afternoon allowed sufficient heating to generate severe thunderstorms across western Wyoming. Instability was enhanced in moist southwest flow ahead of slow moving low pressure in California. |
| Event Narrative | 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. |
