What happened

The episode as NWS BIS wrote it up.

In the mid afternoon hours of Monday July 2nd, Tornado Watch 473 was issued in anticipation of severe thunderstorms developing ahead of an incoming short wave impulse and along a stalled boundary over northwest North Dakota. Later that evening, Severe Thunderstorm Watch 475 was issued over much of west and central North Dakota as a MCS (Mesoscale Convective System) developed in eastern Montana and approached western North Dakota. Severe Thunderstorm Watch 476 was then issued early Tuesday morning of the 3rd to include the remainder of west and central North Dakota as the bowing linear MCS continued to move across the state. Numerous severe thunderstorm warnings were issued during this period. A few reports of large hail and several reports of severe thunderstorm wind gusts were received during the evening hours of the 2nd through the early morning hours of the 3rd.
