What happened
The episode as NWS CYS wrote it up.
Cloudy skies began to clear by early afternoon across the area. Meanwhile an upper level trough of low pressure was situated over western Wyoming, providing lift for thunderstorms to form across the eastern part of the state. As the ground warmed from the sunny skies, the environment became more unstable allowing thunderstorms to form by mid afternoon.
