In the afternoon hours of June 27, 1955, a multiple-vortex tornado moved through the communities of Henry, Morrill, Scottsbluff and Minatare, all located in the state of Nebraska.

[7] For approximately 3 miles (4.8 km) to the east of Henry, the tornado produced no discernible ground damage, before deroofing a farmhouse as it moved into a valley.

The tornado exhibited abrupt changes in direction as it neared the town of Scottsbluff, where it turned to the south and curved east several times.

[13] It tracked over rural areas for the majority of its life, although it directly hit one housing project containing seventeen units; both fatalities recorded from the tornado took place at this location.

[14] The tornado destroyed a total of 146 structures and injured 40 others,[15] along a 40 mi (64 km) path spanning around two hours on the ground.

[23] Northeast of Scottsbluff, near the end of the tornado's path, cycloidal debris marks were documented in aerial shots after the event.
