| Brief Description: The following were destroyed: 15 farm dwellings and service buildings, 25 pieces of farm machinery and equipment, many miles of transmission line, with most of wheat a total loss. (This portion of narrative courtesy of USDA Flash Situation Report.) In addition, major damage to several homes along highway 49. One modular was completely removed from over a viewout basement. A teenage boy sought refuge under the staircase in the basement only to watch a car thrown overhead. He escaped unharmed. However, one woman wasn't so fortunate; the resident of a mobile home that was completely destroyed. The only recognizable parts were the steel girders that ran along the base of the home. She had sought refuge in the bathroom and was holding on to the commode. She was thrown several feet from the homestead and received several injuries. Fortunately, none were serious. | |||||||||||

| Brief Description: Considerable damage to two homesteads; the first being a sturdy brick home. All exterior walls ripped from the home, only leaving only the interior. Home owner ran down the stairs as the tornado hit and avoided injury. Further southeast, a modular home was completely removed from above a viewout basement. It was here that an amazing survival occurred. The homeowner sought refuge in a safe room in the basement and was unharmed, despite the fact a propane tank landed in the basement and began to leak. Breathing became difficult as fumes permeated the saferoom. At the same time, the saferoom began to flood, however the rising water levels dissipated the fumes. In addition, a semi-truck was thrown approximately 100 feet. | |||||||||||

| 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: The same tornado that initially touched down 4 miles north of Wellington in Central Sumner County, SKYWARN reports indicate the tornado crossed the Sumner/Sedgwick County line at 1930, 1 mile west of Peck. Moving northeast at 30 kts, the tornado hit Haysville at 1935, destroying a subdivision just southwest of the South Seneca-South 87th Street intersection where the first 2 fatalities occurred in a mobile home park when a woman and her grandson were killed while running for shelter. (A 6th fatality resulted when an elderly man died from his injuries at a Wichita hospital on May 23rd.) The tornado then moved north along South Seneca Avenue, entering the Haysville Central Business District at 1938. The 3rd fatality occurred at this point when an elderly man was killed in a mobile home at South 75th Street. At the South Seneca/South 71st Street intersection, most of the businesses were heavily damaged or destroyed. Damage summary for Haysville (damaged or destroyed): 150 homes, 27 businesses, 3 churches, 1 library, 4 historic buildings and 1 lodge. The tornado entered South Wichita at 1943 when it crossed South 55th Street. The tornado then veered slightly toward the northwest. At South 47th Street it reassumed a northeast track. Crossing MacArthur Avenue, the tornado leveled the Lakeshore and Pacesetter mobile home parks located just northeast of the South Seneca/MacArthur intersection where the 4th and 5th fatalities occurred, one at each mobile home park. At 1945, the tornado crossed the East Harry Street interchange on I-135 and continued to move northeast, lifting in the College Hill District in Northeast Wichita. Along this entire track, the tornado left a path of destruction 14 miles long and 1/4 to 1/2 mile wide. Damage summary for Sedgwick County: 8,480 buildings (all types) damaged or destroyed. Of these, 2,456 were at least 50% destroyed and 1,109 totally destroyed. M27MH, F43OU, M1OU, M83MH, M68MH, M78MH | |||||||||||

| Brief Description: EVENT NARRATIVE: This is the Kay County portion of tornado #A2. The tornado crossed into Kay County from Grant County and continued to produce significant damage. One home was destroyed and another significantly damaged between the Grant County line and U.S. Highway 177. After the tornado crossed US-177, an anchored mobile home was destroyed and blown to the east, and a tri-level home was destroyed with the top floor blown about 50 yards northeast into some trees, and the ground floor pivoted and was displaced to the northwest exposing the basement where one minor injury occurred. The tornado continued to produce significant tree damage as it moved east-northeast, and blew semi trucks over along Interstate 35 at the Kansas state line. This tornado crossed into Sumner County Kansas. See documentation from the NWS Wichita KS for additional information. EPISODE NARRATIVE: A significant outbreak of severe thunderstorms and tornadoes affected a large part of northern, central, and southern Oklahoma. Tornadoes were most numerous across central and southern Oklahoma, with significant damage occurring over many areas. Severe thunderstorms erupted by mid afternoon across northern and western Oklahoma. Given the potent combination of ingredients in place, storms began to produce tornadoes quickly after initiation. Storm motions of 50 to 60 mph were common. During the mid afternoon hours, severe weather was confined to northern Oklahoma. It was there a long track supercell storm produced tornadoes near the Kansas border - including one rated EF3 - from near Wakita to north of Braman. The capping inversion that had delayed thunderstorm development into central Oklahoma weakened, allowing for explosive supercell development along the dry line along and west of the Interstate 35 corridor. Rapid development and intensification was common with the late afternoon storms, with storms becoming tornadic within a very short time after initiation. This round of storms would directly impact a large part of the Oklahoma City metro area at rush hour, and posed a significant threat to the area. The first tornado in this area occurred in Canadian County. During the next several hours, tornadoes were clustered around the metro area, and at times there were multiple significant damaging tornadoes occurring simultaneously. Several of the tornadoes had long tracks. Damage from the tornadoes was substantial, with numerous structures, vehicles, trees and power poles/lines significantly damaged or destroyed. One of the more intense tornadoes moved across Lake Thunderbird east of Norman destroying numerous boats. More storms developed across southwest and south central Oklahoma, and also quickly became tornadic. By 9 pm, 35 tornadoes had been reported. While the loss of three lives was tragic, the casualties could have been much higher given the storm's fast motions, their intensity, the time of day and the areas impacted. While exact monetary damage figures were not available, it is estimated that losses were in excess of $595 million. At least 450 sustained injuries, most of them minor. Unfortunately three people lost their lives. Note: The large number of injuries and tornadoes made it difficult to associate injuries with specific tornadoes. Injury numbers were included when we had confidence in the numbers. Note: The complex nature of storm evolutions and interactions made the job of classifying tornadoes difficult. This represents our best scientific assessment based on ground and aerial surveys, data from multiple radars, photographic and video evidence and anecdotal information. | |||||||||||

| Brief Description: EVENT NARRATIVE: This is the Grant County portion of tornado #A2. This tornado developed as a multiple-vortex tornado along State Highway 11 southwest of Wakita. The tornado initially moved east and southeast continuing to affect State Highway 11 before beginning an east-northeast movement across Grant County. The tornado was a large and occasionally multiple-vortex tornado as it moved northwest and north of Medford and was embedded within a larger scale circulation that was strong enough to produce damage along a wide area around the tornado path. The tornado caused significant structural damage about 5 miles northwest of Medford and 5 miles east of Renfrow, and many areas of tree and power pole damage. This tornado moved into Kay County. EPISODE NARRATIVE: A significant outbreak of severe thunderstorms and tornadoes affected a large part of northern, central, and southern Oklahoma. Tornadoes were most numerous across central and southern Oklahoma, with significant damage occurring over many areas. Severe thunderstorms erupted by mid afternoon across northern and western Oklahoma. Given the potent combination of ingredients in place, storms began to produce tornadoes quickly after initiation. Storm motions of 50 to 60 mph were common. During the mid afternoon hours, severe weather was confined to northern Oklahoma. It was there a long track supercell storm produced tornadoes near the Kansas border - including one rated EF3 - from near Wakita to north of Braman. The capping inversion that had delayed thunderstorm development into central Oklahoma weakened, allowing for explosive supercell development along the dry line along and west of the Interstate 35 corridor. Rapid development and intensification was common with the late afternoon storms, with storms becoming tornadic within a very short time after initiation. This round of storms would directly impact a large part of the Oklahoma City metro area at rush hour, and posed a significant threat to the area. The first tornado in this area occurred in Canadian County. During the next several hours, tornadoes were clustered around the metro area, and at times there were multiple significant damaging tornadoes occurring simultaneously. Several of the tornadoes had long tracks. Damage from the tornadoes was substantial, with numerous structures, vehicles, trees and power poles/lines significantly damaged or destroyed. One of the more intense tornadoes moved across Lake Thunderbird east of Norman destroying numerous boats. More storms developed across southwest and south central Oklahoma, and also quickly became tornadic. By 9 pm, 35 tornadoes had been reported. While the loss of three lives was tragic, the casualties could have been much higher given the storm's fast motions, their intensity, the time of day and the areas impacted. While exact monetary damage figures were not available, it is estimated that losses were in excess of $595 million. At least 450 sustained injuries, most of them minor. Unfortunately three people lost their lives. Note: The large number of injuries and tornadoes made it difficult to associate injuries with specific tornadoes. Injury numbers were included when we had confidence in the numbers. Note: The complex nature of storm evolutions and interactions made the job of classifying tornadoes difficult. This represents our best scientific assessment based on ground and aerial surveys, data from multiple radars, photographic and video evidence and anecdotal information. | |||||||||||
