The wider storm

Relatively weak shear, less than 1500 J/kg MUCAPE, and deep layer shear less than 30 knots led to slow-moving storms with limited longevity. One stronger storm along a surface boundary west of the Missouri River dropped large hail up to quarter size across Gregory County.

Began near Delmont (43.3300, -98.2300).
