| Brief Description: A F3 tornado touched down northwest of Fairfax and traveled northeast across rural areas of Osage county before dissipating just west of Bowring. The one community it did effect was Little Chief. Oil tanks southwest of Little Chief were taken off their foundation and rolled a quarter of a mile. In Little Chief a RV was destroyed and there was considerable tree damage. In a field not far from Little Chief seven cattle were killed. Along Highway 60 to the northeast of Little Chief a house and garage were completely swept from their foundation. At the same location a barn was destroyed and three horses were killed. Further to the northeast as the tornado entered the Tall Grass Prairie Preserve, it produced additional significant tree damage. Throughout the path of the tornado up to 30 power poles were blown down causing power outages across a significant part of Osage county. The F3 damage was classified at two locations: the first was near where the cattle were killed--this was the only location that showed the scouring of grasses along the path; the second location was in the western sections of the Tall Grass Prairie Reserve where an Oak Forest was heavily damaged. Although the one house was swept off its foundation, it was clear that this house's anchoring failed prematurely. On this property there were several examples, especially with vegetation, that hinted that this stretch of the tornado track was probably less than F3 intensity. | |||||||||||

| Brief Description: The tornado started moving NE before becoming influenced by the outflow of the storm and darted back to the SE. The tornado ripped the roof off one home and blew out two walls and a roof of another. However, the tornado took dead aim on one home about 3.5 miles SE of Mulvane and completely removed it from it's foundation. Two inhabitants were under the staircase in the basement and escaped with only minor injuries. | |||||||||||

| 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: 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. | |||||||||||
