What the National Weather Service wrote
Trained spotters reported a brief (10-second) tornado touchdown just east of the town of Chugwater. The tornado remained over open country. Confirmed by official NWS Storm Survey.
The wider storm
An intense, long-lived supercell initially developed near the town of Chugwater over the higher terrain of the central Laramie Range around 3:00 PM on 6/23, tracking to the east-southeast across southern Platte and Goshen Counties through approximately 7:00 PM. A small, terrain-driven area of low pressure and resultant cyclonic flow resulted in moisture pooling and backed, easterly near-surface flow near the track of the storm which resulted in a favorable environment for tornadoes. The cyclic supercell produced 5 separate confirmed tornadoes, most notably including an EF-2 tornado which developed near the town of Hawk Springs. A swath of large hail up to two inches in diameter also occurred with this storm. A separate storm over far northwestern Converse County also produced a brief tornado that afternoon. A second round of strong to severe thunderstorms impacted Platte and Goshen Counties later in the day.
Began near Chugwater (41.7745, -104.7474).
