| Episode Narrative | An upper level trough over southern Canada combined with numerous surface boundaries to trigger evening severe thunderstorms across western North Dakota and eventually into south central North Dakota. Numerous reports of large hail were received across the west where initially isolated splitting storms developed. As the convection moved east into south central North Dakota, a quasi-linear storm structure developed and intensified as it moved across Oliver County and eventually into the Bismarck area. The storms weakened east of Bismarck shortly before midnight. |
| Event Narrative | The very large hail damaged a patrol car. |
