Thunderstorms developed during the afternoon and evening hours as an inverted surface trough, extending from low pressure in western South Dakota, and a warm front, extending from far south central North Dakota into the James River Valley, moved through. The initial severe storms produced tornadoes in Logan County and in Stutsman County. Both tornadoes touched down in open fields and impacted no structures. Both were rated EFU (Unknown) by National Weather Service policy as there was no damage to evaluate. Hail then became the main threat with the largest hail of two inches in diameter falling near Woodworth. Later in the event strong thunderstorm winds and torrential rain became the main threats over the James River Valley. The city of Jamestown was hit by hail, high winds and three to five inches of rain, causing flash flooding. There was also flooding along Interstate 94 west of Jamestown, in Stutsman County. In Jamestown, streets and parking lots were flooded with several feet of water, stranding motorists. In and around the city of Marion, thunderstorm wind gusts estimated at 90 mph caused damage to the local elevator, dislodged two large grain bins, and caused home and tree damage.

The tornado touched down in an open field north of Burnstad and impacted no structures. There was no damage to evaluate. By National Weather Service policy the tornado is rated EFU (Unknown).

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Slight Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 16:42 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
