Episode Narrative Tornado Watch number 611 was issued in the early afternoon in anticipation of an increasing threat for thunderstorms across west and central North Dakota for the afternoon and evening hours of July 8th. Destabilization occurred behind a northward advecting warm front, where storms eventually developed across the south. Veering low level winds in the warm sector also created an environment conducive for tornado development. Numerous severe weather warnings were issued. Six tornadoes occurred during this event and all were rated EF0 as there were no damage reports.
Event Narrative Multiple public reports of a tornado were called in to the Dickinson 911 dispatch center. This tornado occurred south of Manning in the open country of Dunn County. No damage was reported. The same thunderstorm complex that produced this tornado in Dunn County produced tornadoes later in Mercer County. See Mercer County tornado entries.
