| Episode Narrative | Easterly low-level wind flow brought moisture into Fremont and Natrona counties following passage of a weak cold front. Southwest flow aloft helped to move thunderstorms off the higher terrain of the Wind River Range and into the moisture laden air in the Wind River Basin. Favorable wind shear profiles led to the development of a few tornadoes and large hail from mid afternoon to early evening. |
| Event Narrative | A tornado was observed near Sand Mesa Road in northern Fremont County. Several power poles were toppled as the tornado traveled northeast toward a rural ranch before dissipating. |
