2015-06-16 · near East Thermopolis, Hot Springs, Wyoming

Event narrative

Two inch diameter hail fell in the Wind River Canyon knocking out windows in vehicles traveling State Highway 789.

Wider weather episode

A stalled frontal boundary remained near the Continental Divide on Tuesday, June 16. Thunderstorms erupted during the early afternoon as an upper level disturbance passed over the area and combined with the moist, upslope flow north of the boundary. The favorable wind profile enabled one thunderstorm to become a supercell as it moved east-southeast across Hot Springs and northern Fremont counties. The storm produced large hail which damaged car windows in the Wind River Canyon south of Thermopolis. The same storm also spawned a funnel cloud near Lost Cabin. Another storm developed in Natrona County and also produced large hail southwest of Casper.
