The earliest tornado report came in around 3:51 p.m. local time of a tornado touching down approximately five miles southwest of Douglas, Wyoming. That trained spotter report then prompted the National Weather Service office to continue the tornado warning for an observed tornado. The final report of this storm came around 4:39 p.m. local time when law enforcement noted a tornado moving to the southeast.
