Report relayed from storm chaser to KAKE TV, who transmitted the report to NWS-Topeka. An HP-supercell thunderstorm tracked across southern Anderson Couty the evening of the 28th. The supercell thunderstorm produced a tornado that touched down just east of the city of Colony.
The tornado moved northeast and was on the ground for nearly 9 1/2 miles. It lifted around 5 miles east of Welda. The average width of the tornado was 250 yards. Ultimately, over 40 structures were damaged but remarkably no injuries occurred. Most structures reported minor damage. However, numerous trees were toppled and outbuildings destroyed. Power lines were downed resulting in power loss to a number of southeast Anderson county residents. At least one barn was destroyed and several homes received significant structural damage. Windows were blown out of a number of homes as well as cars. The most significant damage occurred to a large span metal horse arena. This arena had steel girders and concrete footings. It was lifted out of the ground and destroyed. Horsemen in the arena at the time the tornado approached found safety in a small interior room and were uninjured. However, a horse and rider who remained in the arena were both thrown 100 feet into a field. But neither the horse nor the rider was seriously injured. Another horse had a steel pipe driven through its head but was not killed. The resident of this property lost his billfold to the tornadic wind. However, in the clean-up the next day, he found his billfold in a bird's nest nearby. An elderly lady who was very deaf was asleep in her house when it was hit by the tornado. The house received significant damage. But she was unhurt and had no idea what happened until a neighbor found her later and explained her house had been hit. The Garnett police chief was racing south behind the storm in his patrol car and nearly lost control when he came upon 3 to 4 inches of solid ice (hail) on the road. Reports indicated that a large amount of hail had fallen along a parallel path 3 to 5 miles north of the tornado. At one farmstead, a railroad car used as a storage shed was pushed off its foundation and rolled three times along the ground, smashing cattle panels and fences. The tornado was rated EF-1.
