An early spring storm impacted central Wyoming during the afternoon hours of May 6th. A trough  sliding through the area moved a cold front across central Wyoming. This system decreased the stability of the air across central Wyoming, allowing thunderstorms to develop. 

In general, thunderstorms began to develop around 1pm, with stronger storms developing close to 2 pm. Some storms were quite strong, with one storm producing a weak tornado, and another producing large hail.

The Tornado

A strengthening thunderstorm was noted across Fremont county around 2 pm. Radar images began to show classic signatures demonstrating tornadic activity at around 2:05 pm. The first notification confirming a visual sighting of the tornado arrived around 2:10 pm, with another phone call received within 15 minutes for the same tornado. One spotter was able to obtain both still images, and a video of the tornado as it moved across Fremont county.
