Survey Summary:
A tornado tracked for nearly four miles over approximately 21
minutes, leaving a path of significant damage. The event began
around 5:55 PM CDT when the tornado touched down in an open field
between 168th and 169th Streets, just to the west of 442nd Avenue.
The tornado initially tracked to the east, and by about 6:02 PM,
it crossed 442nd Avenue. The tornado then turned and started
tracking south. The core of the tornado passed about 150 yards to
the west of a farmstead, but at approximately 6:03 PM, the tornado
was close enough to the farm to start causing significant damage.
In fact, video evidence shows debris being lofted into the air
before the tornado made its closest approach. The main residence
was completely destroyed. An attached garage was dislodged and
swept clean from its cement foundation; however, a vehicle in the
driveway did not move. The remainder of the house lost its entire
roof and many exterior walls, though interior walls remained
standing. One outbuilding was completely destroyed, and many
others sustained significant damage. Along the southern edge of
the property, a line of nine grain bins was completely swept away.
The residents were not home at the time of the tornado, but a
beloved horse was killed. At 6:06 PM, the tornado crossed 169th
Street and continued south through cropland. Aerial photos
revealed that between 169th and 170th Streets, the tornado ripped
through several rows of erosion shelterbelt trees. Trees in the
path were void of branches, snapped at their bases, and in some
spots, reduced to nothing more than stubs. Continuing south, the
tornado crossed 170th Street at around 6:11 PM, and continued
across a lake and more cropland, eventually crossing 171st Street.
By approximately 6:16 PM, the tornado weakened and dissipated
just north of 172nd Street, bringing its 21-minute duration to an
end.
