In the late afternoon of Thursday, July 10th, Tornado Watch 678 was issued for much of the Bismarck County Warning Area in anticipation of severe thunderstorms with tornado potential developing along a warm frontal boundary that stretched across central North Dakota. An upper level trough was also advecting into the region resulting in cooling temperatures aloft and eroding the afternoon cap. Numerous severe thunderstorm warnings and several tornado warnings were issued. Multiple reports of large hail and two tornado reports were received across south central North Dakota during the late afternoon and early evening hours.
