What happened

The episode as NWS BYZ wrote it up.

An unstable southwest flow aloft was over the Billings Forecast Area. Large-scale ascent ahead of a midlevel trough tracked eastward across the northern Rockies. Thunderstorms developed over the mountains of southwest Montana and moved east onto the adjacent plains. Wind shear of around 50kts supported storm organization resulting in organized thunderstorm clusters and supercells, some of which produced large hail and severe outflow winds.

What forecasters said that day

The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Billings, MT wrote its last area forecast discussion before the first event at Jun 27, 12:12 PM MST, 17 minutes earlier.
