| Brief Description: Tornado that began in eastern Trego county, steadily moved northeast before dissipating north of Hays. The tornado hit several farms in rural Ellis county and slammed into sparsely populated Yocemento. After leaving Yocemento, the tornado tore through a feedyard and on across other parts of rural Ellis county. Fortunately, the tornado stayed just west and north of populated Hays where a high school football game was in progress. The tornado damaged or destroyed 10 homes, a grain elevator, many outbuildings, a tractor and a feedlot. During the weaker moments of the tornado, it moved a 14,000 pound tractor 30 yards. One modular constructed home on a concrete slab was completely destroyed with the remains carried 1/2 of a mile. A steel I-beam from a concrete building travelled several hundred yards, eventually crashing into a grain elevator. Three empty anhydrous ammonia tanks were moved causing a leak of a benign amount of vapour. An injury occurred to a male driving a tractor-trailer rig on Interstate 70. | |||||||||||

| Brief Description: This tornado entered Ellis county from Trego county at 440 PM and continued a a northeast and easterly track. It did speed up at the end of it's life and as is typical, decreased in size. Another tornado was video taped just north and west of this tornado (during the same time), but was just across the county line. A brick building (that was very sturdy) was destroyed and strewn for hundreds of yards into a field. "Huge" cottonwood trees were either uprooted or snapped off at about five feet. A 250 gallon oil tank was moved 1.5 miles and was found lodged into a grove of trees. | |||||||||||

| Brief Description: EVENT NARRATIVE: This tornado moved over a sparsely populated area but did EF2 damage to trees. It moved northwest towards the end of it's life cycle. EPISODE NARRATIVE: An anonymously strong upper level system allowed everything to come together at the surface to produced what is perhaps the biggest tornado outbreak to ever occur in the Dodge City CWA! Fifty-five tornadoes were documented during that afternoon and evening! Some of the tornadoes were very large and damaging. The character of the supercell thunderstorms that day had similarities to the storms that produced the Greensburg tornado a little over a year after. In fact there was one tornado that was just as large and perhaps could have been just as damaging that was headed towards the small Kiowa county town but fortunately turned and dissipated. | |||||||||||

| Brief Description: Initial touchdown occurred 1 mile southwest of Hoisington. The tornado rapidly achieved F3 intensity as it entered the west side of town. Moving northeast around 20 mph, the tornado intensified to F4 within 2-3 minutes. While crossing northwest Hoisington, the tornado inflicted a path about 2 miles long and about 2 blocks wide of almost complete destruction. Damage summary: 182 homes destroyed, 52 homes with major damage, 180 homes with minor to moderate damage, 12 businesses destroyed, tore the roof off the hospital, and severed power to most (if not all) areas on the northwest and north sides of town. As the tornado exited through the north side of town it weakened rapidly, inflicting F1-F2 damage as it approached Deception Creek which runs in a southeast to northwest manner 3 miles northeast of town. Once the tornado crossed the creek, it suddenly turned toward the northwest where it damaged two farmsteads shortly before dissipating. One man, 69 years of age, was killed when a minivan fell on him. There were 28 injuries of which 3 were critical. M69PH | |||||||||||

| Brief Description: A significant tornado (rated F2 based on damage survey) touched down 8 miles SW of Hill City near Road 220 and Road J at approximately 4:20 pm CDT. As the tornado continued northeast toward Road 260 and Road M it damaged two homes and destroyed a detached garage. One home suffered roof damage while another had part of the roof from the upper story removed. Significant and continuous tree and power pole damage was noted for one mile south of this location. Some of this damage was likely produced by an intense rear-flank downdraft accompanying the southern periphery of the tornado. As the tornado crossed Highway 283 approximately 3.5 miles south of Hill City, it caused structural damage to a hangar used as storage. A boat, a small four-wheeler and a camper were either heavily damaged or destroyed, with debris rolled or bounced between one-half and three-fourths of a mile. The tornado crossed the intersection of Road 290 and Road O producing tree damage. The tornado ultimately lifted about a half mile northeast of this location at approximately 4:48 pm CDT. | |||||||||||

| Brief Description: EVENT NARRATIVE: This was a large tornado that produced EF2 damage. It turned northwest towards the end of its life cycle but dissipated before reaching Arnold. Damage was done to trees, large power poles, a large tank, a barn and hay bales. EPISODE NARRATIVE: An anonymously strong upper level system allowed everything to come together at the surface to produced what is perhaps the biggest tornado outbreak to ever occur in the Dodge City CWA! Fifty-five tornadoes were documented during that afternoon and evening! Some of the tornadoes were very large and damaging. The character of the supercell thunderstorms that day had similarities to the storms that produced the Greensburg tornado a little over a year after. In fact there was one tornado that was just as large and perhaps could have been just as damaging that was headed towards the small Kiowa county town but fortunately turned and dissipated. | |||||||||||
