Episode Narrative A strong cold front and upper level disturbance moved across the central and eastern counties in the Billings County Warning Area during the late afternoon and evening hours of the 13th. Several thunderstorms developed across Northern Stillwater and Sweet Grass Counties before evolving into Supercell thunderstorms over Northern Yellowstone County. These thunderstorms then merged into a squall line across Eastern Yellowstone County and Treasure County before moving across Rosebud, Custer and Fallon Counties. Very large hail and damaging winds accompanied these thunderstorms with widespread damage reported across these areas.
