| Episode Narrative | In the mid afternoon hours of Monday, July 12th, Severe Thunderstorm Watch number 461 was issued for far western North Dakota. This was in anticipation of thunderstorms developing ahead of a potent short wave trough advecting northeast across the central Rockies and into the Northern High Plains region. Ahead of this feature, strong moisture advection combined with steep lapse rates and strengthening vertical shear parameters to create a favorable atmosphere for organized storms. Severe Thunderstorm Watch number 463 was issued later Monday evening to include all of west and portions of central North Dakota, as ongoing severe thunderstorms over western North Dakota were expected to continue and advect to the east along and ahead of a frontal boundary stretched across the western Dakotas. Several severe thunderstorm and tornado warnings were issued. Several reports of large hail, two reports of severe thunderstorm winds, and one confirmed tornado occurred during this episode. |
