| Brief Description: EVENT NARRATIVE: The tornado touched down and caused some damage to a barn and some trees limbs were partially torn off. As the tornado continued to move to the northeast more significant damage occurred. A house was damaged with the roof being torn off of a house with 2 exterior walls being blown out (EF2 damage). Two garages were also destroyed and a riding lawnmower was removed from the garage and moved 100 yards downstream. Three people took shelter from the tornado in the basement and were unharmed. EPISODE NARRATIVE: Severe thunderstorms developed during the afternoon and evening hours of May 10th, 2010, ahead of an approaching dry line and warm front. This dynamic environment coupled with an unstable airmass led to the development of thunderstorms to the west and south of Wichita, Kansas with tornado producing supercells moving across portions of South Central Kansas. Two supercells in particular produced significant damage across portions of Kingman, Sedgwick and Cowley counties with some of the damage classified as EF-2 damage by survey teams. | |||||||||||

| Brief Description: EVENT NARRATIVE: This 3/4 mile wide tornado produced EF3 damage and unfortunately claimed two lives. A husband and wife were parked on highway 54 approximately 2 1/4 miles east of Cairo. The tornado picked up their car and carried it approximately 1700 feet NNE into a wheat field (they were not discovered until the next morning at about 9 AM). The female occupant was ejected and was found 30 feet southwest of the wreckage. The male was still strapped in his seat. The car was nearly unrecognizable. A second vehicle (3/4 ton truck) was parked 20 yards behind the aforementioned car. It also went airborne briefly but got lodged on the north side ditch. The two male occupants received numerous cuts and bruises but were otherwise unhurt. They both claimed it was extremely cold immediately after crawling out of their vehicle with heavy vapor breath noticed. This tornado destroyed a home about a mile north and the collapsed east wall trapped a male in the bathtub where he had taken cover. Help was needed in lifting the wall off of him but he claimed he was not hurt. Other homes in the tornadoes path received minor to moderate damage. 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: EVENT NARRATIVE: This killer tornado formed just east of another large but dissipating tornado that was approaching Macksville. Unfortunately a law officer watching the dissipating tornado was unaware that this one was rapidly forming and could not get out of harms way. His car was thrown at least 1/4 of a mile and was found in a field. He died several days later from catastrophic injuries received in the crushed vehicle. EF3 damage was done to over a dozen farms, trees, machinery, vehicles, pivot irrigation sprinklers and power poles. EPISODE NARRATIVE: A destructive tornado, the first 5 rating on the new Enhanced-Fujita Scale and the first 5 classification since May 3, 1999 when an F5 tornado ripped through Moore, Oklahoma occurred on this day. There were 12 tornadoes during about a 4 hour period, one a little over 2 miles wide! Two of the tornadoes existed for over 1 hour as they churned up the ground, leveling homes and causing fatalities along their path. Miraculously, on 13 people perished, 11 in Greensburg - a miracle because over 90 percent of the town of Greensburg was literately wiped off the face of the earth. Another round of tornadoes occurred the following day across generally the same area. Nearly 250 pivot irrigation sprinklers were damaged or destroyed during the 2 day outbreak. Due to the number of sprinklers involved and the lack of replacements, some farmers would be out of service for over 1 year. | |||||||||||

| Brief Description: This very large tornado moved southeast across much of Pratt. Damage was rated a STRONG F2. There were 14 homes destroyed, 15 with major damage and 230 with minor damage. Over 50 Pivot sprinklers were damaged or destroyed. Despite the very heavy damage, there were no injuries thanks in part to adequate warnings. | |||||||||||

| Brief Description: EVENT NARRATIVE: This wedge tornado was occurring simultaneously to another large but smaller tornado (within several miles). Damage was done to houses, trees and pivot irrigation sprinklers. EPISODE NARRATIVE: Unbelievably, an outbreak of tornadoes, some very large in size, raked the earth in basically the same area as the day before when Greensburg was nearly completely leveled. Although some of the tornadoes were large and apparently very strong, there was no loss of life on this day. A National Weather Service assessment team was in an area about 30 minutes before a tornado moved through. They also saw one tornado during the storm survey of damage that was produced the day before. | |||||||||||
