What happened

The episode as NWS BIS wrote it up.

In the mid-evening hours of Monday, June 21st, Severe Thunderstorm Watch 375 was issued for ongoing severe thunderstorms over eastern Montana advecting east into western North Dakota, and in anticipation of further convective development and intensification across west and central North Dakota into the early morning hours of Tuesday, June 22nd.

Strengthening low level warm air advection along a northward surging warm front, combined with divergent flow aloft ahead of an approaching mid level short wave trough, were the key ingredients for severe convection. Multiple severe thunderstorm warnings were issued, along with several flood advisories for excessive rainfall. Four reports of large hail and numerous reports of severe thunderstorm wind gusts were received.
