Episode Narrative This event set up as another nice case of elevated convection. On the morning of the 20th, an area of surface low pressure was located near Mobridge, South Dakota, with a warm front arching to the southeast (down into eastern Nebraska).

Thunderstorms initially flared up near Crookston, MN, and moved northeast at 40 to 50 mph.
