What happened

The episode as NWS BIS wrote it up.

During the early to mid evening hours of Wednesday, June 30th, Severe Thunderstorm Watch number 434 was issued for southwest and west central North Dakota in anticipation of strong to severe thunderstorms over southeastern Montana advecting northeast into North Dakota. These thunderstorms were associated with a weak mid level wave lifting northeast into the Northern Plains. The watch was later expanding to include north central North Dakota as a nocturnal low level jet developed and intensified across the Dakotas, helping to sustain severe convection into the early morning hours of Thursday, July 1st.

Several additional severe thunderstorm warnings were issued early Thursday morning. Several reports of severe thunderstorm wind gusts and two reports of large hail were received.

Please see the storm data entry for June 30th for additional reports related to this episode.
