 Brief Description: EVENT NARRATIVE: At least 4 mobile homes and 1 foundation home were destroyed by a large tornado. Other homes and outbuildings sustained minor to moderate damage. Widespread tree and power line damage was also noted along its track, and some high tension lines were downed. This tornado is labeled #E3. Monetary damages were estimated. 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 long track tornado developed over far southeast Jefferson County, near the Red River, and continued northeast into Love County crossing through rural farmland north of Courtney, Rubottom and Oswalt. The tornado then crossed into Carter County, with sporadic damage noted in the sparsely populated areas in the southwest part of the county. The tornado appeared to reach its maximum width and intensity as it approached and moved through Lone Grove. The tornado destroyed or severely damaged numerous mobile homes, homes and businesses in and around Lone Grove. Numerous mobile homes were completely obliterated with few recognizable pieces left. EF4 damage was noted at two locations, one in Lone Grove and the other in the Majestic Hills area north of Ardmore. Numerous vehicles were rolled or thrown, some for considerable distances. Six of the fatalities occurred in mobile homes and one in a well-built home that sustained EF4 damage. The eighth fatality occurred when a truck driving south on Interstate 35 was hit by the tornado killing the driver. The tornado continued northeast, with major damage reported in the Majestic Hills addition and crossing Interstate-35 about a mile and a half north of the Prairie Valley Road exit. At least eight homes and a small private school were destroyed in the Majestic Hills neighborhood. It moved through rural areas of Northeast Carter County to the east of Springer. Approximately 46 people were injured, with 14 seriously injured. Eight people died in the Lone Grove area. At least 114 homes were damaged or destroyed, with at least 3500 losing power in and around Carter county. Debris from this tornado was picked up as far away as Sulphur. Monetary damage estimates were not available. EPISODE NARRATIVE: Thunderstorms developed early in the afternoon, from near the Lawton area, northeast toward the Oklahoma metro area. Thunderstorms became severe relatively quickly as they moved through Caddo and Grady counties, and began to show signs of rotation as they moved toward western Oklahoma City. One supercell thunderstorm spawned several tornadoes as it moved through western and northern Oklahoma. Sporadic damage was reported along its path, some of it significant as it moved through northern Oklahoma county and southern Logan county. Other supercells developed near the same areas of Caddo and Grady counties and moved northeast. Some locations received several rounds of very large hail through the afternoon. Later in the afternoon, a second area of thunderstorms developed over northern Texas. Several supercell thunderstorms developed and moved northeast toward the Red River. One supercell thunderstorm moved northeast over Clay county and northwest Montague county. A tornado developed as it moved into Jefferson county near the Red River. It continued northeast through western Love county and into Carter County. Significant damage was reported in and around the Lone Grove area and over the far north sides of Ardmore. There were eight fatalities in and around Lone Grove. The tornado crossed Interstate 35 and eventually crossed into southern Murray county. Wind damage was reported in Coal and Atoka counties. Minor injuries were reported with the Atoka county thunderstorms. Monetary damages were estimated.

 Brief Description: This nighttime tornado is the first of three Oklahoma tornadoes produced by a large supercell that moved across south central Oklahoma. The tornado moved east-southeast for six miles before dissipating. Several homes lost all or part of their roofs with several other homes receiving shingle damage. Four barns were damaged or destroyed. One pole barn had the poles, that were buried three feet deep, pulled out of the ground. A cinder block building also collapsed. Many trees and power lines were downed or damaged by the tornado. Two of the trees were over 100 years old. Three horses were also injured by the tornado. This was the first of three tornadic events in two days for Oklahoma. The other two events occurred on the afternoon of May 8 and on May 9, 2003 (see appropriate storm data). The five tornadoes that occurred in south central Oklahoma all happened after midnight with the strongest tornadoes producing F2 damage. One large supercell produced the three strongest tornadoes of the night.

 Brief Description: EVENT NARRATIVE: The thunderstorm that produced this tornado began near Breckenridge and Graham, TX. The storm moved northeast. A long-track tornado developed over far southeast Jefferson County, near the Red River. The tornado continued northeast into Love County crossing through rural farmland north of Courtney, Rubottom and Oswalt. Sporadic structural damage was noted in both Jefferson and Love counties, with tree damage also seen. The tornado then crossed into Carter County, where it did its most significant damage in and around the Lone Grove area. The tornado continued northeast, with major damage reported in the Majestic Hills addition and crossing Interstate-35 about a mile and a half north of the Prairie Valley Road exit. At least eight homes and a small private school were destroyed in the Majestic Hills neighborhood. It moved through rural areas of Northeast Carter County to the east of Springer. Approximately 46 people were injured, with 14 seriously injured. Eight people died in the Lone Grove area.

One supercell thunderstorm spawned several tornadoes as it moved through western and northern Oklahoma. Sporadic damage was reported along its path, some of it significant as it moved through northern Oklahoma county and southern Logan county. Other supercells developed near the same areas of Caddo and Grady counties and moved northeast. Some locations received several rounds of very large hail through the afternoon. Later in the afternoon, a second area of thunderstorms developed over northern Texas. Several supercell thunderstorms developed and moved northeast toward the Red River. One supercell thunderstorm moved northeast over Clay county and northwest Montague county. A tornado developed as it moved into Jefferson county near the Red River. It continued northeast through western Love county and into Carter County. Significant damage was reported in and around the Lone Grove area and over the far north sides of Ardmore. There were eight fatalities in and around Lone Grove. The tornado crossed Interstate 35 and eventually crossed into southern Murray county. Wind damage was reported in Coal and Atoka counties. Minor injuries were reported with the Atoka county thunderstorms. Monetary damages were estimated.

 Brief Description: This is the second Oklahoma tornado of three that was produced by a supercell that moved across south central Oklahoma. This strong F2 tornado moved southeast and then turned more easterly before dissipating within Lake Murray State Park. A double-wide mobile home was destroyed by the tornado. A brick home lost two of its walls and the roof was removed. Four other homes were also heavily damaged with roofs removed and walls damaged. Two barns were also damaged. The tornado crossed Interstate 35 near mile marker 21. A tractor trailer was blown off the interstate just south of this location. The state park sustained some tree damage on the southwest side of Lake Murray. This was the first of three tornadic events in two days for Oklahoma. The other two events occurred on the afternoon of May 8 and on May 9, 2003 (see appropriate storm data). The five tornadoes that occurred in south central Oklahoma all happened after midnight with the strongest tornadoes producing F2 damage. One large supercell produced the three strongest tornadoes of the night.

 Brief Description: This description was taken almost entirely, and with minimal editing, from a damage survey conducted Monday May 26th (Memorial Day), the day after the tornado, by a National Weather Service meteorologist. This tornado, rated F2, began 5 miles east of Criner, or 7 miles west-southwest of downtown Purcell, in southern McClain County. The beginning time of this tornado is not entirely certain but is believed to be near or just after 16:00 CST. This tornado tracked just south of due east for 6 miles, ending about 4 miles northwest of Wayne or 4 miles south of downtown Purcell at around 16:24 CST. At its widest, the damage path was estimated to be 3/4 mile wide. Numerous power lines were downed, prompting the temporary closing of both Highways 24 and 74 for a time during the evening. At least 18 dwellings, including mobile homes and permanent dwellings, were destroyed or suffered major damage. This probably was a multiple-vortex tornado, at least in its latter stages, based on eyewitness reports. No one was killed or seriously injured by this tornado, but two minor injuries were reported. Damage began along a concentrated path from along Highway 24 around 3 miles south and 1 mile east of Woody Chapel (which is located at the intersection of Highways 39 and 24 about 3 miles south of Washington). Details are described below, highlighting six areas along the damage track. Along Hwy 24, 5 miles east of Criner, sheet metal was scattered over about a 1/4 to 1/2 mile path, apparently the remnants of a destroyed outbuilding. Several large trees were toppled or heavily damaged in this area. Damage was F1. Tree damage also was noted over a larger area 1 mile west of this location (or 3 miles south of Woody Chapel on Highway 24), along with a few pieces of sheet metal debris. Since damage in this area was more minor (small to medium size branches broken) and not concentrated, straight-line winds were considered the likely source. Also along Hwy 24, from Hwy 112 southward for about a mile, power lines were downed along a 1/4 to 1/2 mile stretch of the road. Considerable debris was found from fallen trees, metal outbuildings, etc. Damage was F1. About 1 mile east of Hwy 24 and 1 mile south of Hwy 112, a home was unroofed. Widespread but mostly minor tree damage was noted, with trees uprooted and/or branches snapped off. Aside from the home with the damaged roof, there were few if any other manmade structures in the area. Damage probably was F1, but an exact determination could not be made since the roof was being repaired at the time of the survey. On Emu Road, 1/2 to 1 mile south of Hwy 112 and 2 miles east of Hwy 24, one permanent home was destroyed. Numerous large trees were downed - some snapped off, and others uprooted. Several of the uprooted trees fell toward the northwest, others to the southwest. Damage was considered F2. At Highway 74 and Horse Road, (3.5 to 4.5 miles east of Hwy 24 and 1 mile south of Hwy 112), the worst damage and widest damage path (about 3/4 mile wide) were in this area. Power lines were downed along Hwy 74 for nearly a mile. Numerous large trees were snapped off or uprooted. In one area between the two roads, nearly every tree suffered some kind of significant damage. Two mobile homes were destroyed along Horse Road. One was blown east and landed across the street near a church. The other rolled three times and landed 50 to 100 feet northeast of its original location. Two women, a mother and daughter, were inside the second mobile home and were lucky to escape with only minor injuries. Metal outbuildings, satellite dishes, fences, and at least one pickup truck were destroyed - mostly by impacts from other blown objects. However, the church, which was brick, sustained only minor structural damage to the exterior, as the roof was intact and only a few shingles were missing. (Broken windows in the church led to more substantial damage on the interior as rain and wind entered the building.) Damage in this area was considered F2, but the fact that the church escaped with such minor damage to its exterior suggests either a lower rating or the possibility of a multiple-vortex tornado. At least one eyewitness indicated a second tornado. Although the entire damage track appeared consistent and more-or-less continuous, suggesting only one tornado, the eyewitness account and the observed gradients in damage intensity suggest that this probably was a multiple-vortex tornado, at least in its latter stages. From 1/4 to 1/2 mile east of Horse Road, a large home suffered major damage, with most of the second floor destroyed. Downed trees were widespread. Damage was rated F2. Another home immediately east of this location lost part of its roof. But farther east, near Interstate 35, several homes were undamaged and no significant damage could be found - except for a lone uprooted tree immediately west of the interstate. Summary of events of the afternoon and evening of May 25, 1997: Severe thunderstorms developed during the afternoon in central Oklahoma and spread into southern Oklahoma during the late afternoon and evening. In all, thirteen tornadoes were confirmed, including an F2 tornado that tracked for 6 miles through McClain County southwest of Purcell. Some minor injuries were reported with one of the tornadoes, but no fatalities or serious injuries occurred. Reports of 3-inch hail, severe straight-line winds, and lightning damage were also received. One particularly strong supercell storm tracked across central Oklahoma, reaching its maximum strength and producing 3 tornadoes and extensive straight-line wind damage over Grady and McClain Counties. What follows here is an excerpt from a damage survey conducted by a National Weather Service meteorologist on May 26th, the day after the storm. "A large severe thunderstorm moved through northern and central Grady County into central and southern McClain County during the late afternoon on Sunday, 25 May 1997. Several reports were received immediately after the storm indicating significant wind damage, especially in southern McClain County southwest of Purcell. There also were numerous confirmed tornado sightings by storm spotters, chasers, local emergency management officials, and local residents. Findings indicate that 3 tornadoes occurred in this area. Most of the damage, and all of the significant structural damage, resulted from the first two tornadoes. Widespread tree damage in some areas, especially in McClain County, was attributed to straight-line winds. The first tornado, rated F1, began 3 miles northeast of Tabler at 15:14 CST and tracked just south of due east for about 2.5 miles before dissipating 2.5 miles SSW of Middleberg at 15:24 CST. Structural damage was confined to a dairy farm near the beginning of the track; otherwise, this tornado remained over mostly open country. The second and more significant tornado, rated F2, began 5 miles east of Criner, or 7 miles WSW of downtown Purcell, in southern McClain County. The beginning time of this tornado is less certain but is believed to be near or just after 16:00 CST. This tornado also tracked just south of due east for 6 miles, ending about 4 miles NW of Wayne or 4 miles S of downtown Purcell at around 16:24 CST. Numerous power lines were downed, prompting the temporary closing of both Highways 24 and 74 for a time Sunday evening. At least 18 dwellings, including mobile homes and permanent dwellings, were destroyed or suffered major damage. This probably was a multiple-vortex tornado, at least in its latter stages, based on eyewitness reports. A third small tornado, rated F0, formed around 16:32 CST and lasted about one or two minutes. It damaged an outbuilding and a few trees 2 miles NNE of Wayne in Southern McClain County, about 4 miles east of where the second tornado ended. No one was killed or seriously injured by any of the tornadoes, but several minor injuries were reported. " The remaining 10 tornadoes were associated with other severe thunderstorms, mainly across central and southern Oklahoma. The strongest of these occurred south of Duncan in Stephens County at 17:36 CST. Spotter and damage reports rated this as an F1 tornado. The remaining 9 tornadoes were all rated F0 and resulted in little or no damage. In chronological order, these tornadoes occurred on the Caddo Comanche County line between Cyril and Fletcher (16:27CST), south of Maysville in Garvin County (17:28 CST), east of Joy in Murray County (18:07 CST), south of Stratford in Garvin County (18:13 CST), east of Roff in Pontotoc County (18:53 CST), northeast of Mill Creek in Johnston County (19:20 CST), west-northwest of Madill in Marshall County, (19:43 CST), north of Tupelo in Coal County (19:48 CST), and northwest of Newkirk in Kay County (21:10 CST). Severe straight-line winds were estimated at up to 80 mph (southwest of Fittstown in Pontotoc County). Wind damage from thunderstorm winds occurred north of Tabler in Grady County, southwest of Purcell in McClain County, in Wynnewood in Garvin County, west of Hardy in Kay County, and west of Antlers in Pushmataha County. Hail up to 3 inches in diameter fell south of Stratford in Garvin County, and lightning damage was reported south of Duncan in Stephens County. See preceding individual Storm Data entries for further details and additional reports.

 Brief Description: This strong F2 tornado is the final of three Oklahoma tornadoes produced by a supercell that moved across south central Oklahoma. The tornado was seen by spotters touching down approximately a mile east of the Carter-Marshall county line. The tornado then moved northeast before dissipating north of Antioch. The most significant damage was sustained in an area about three miles west of Antioch along Highway 70. A wood frame home lost its roof and two walls. Two barns also lost roofs in this area. A forty foot by one hundred foot barn south of Highway 70 was heavily damaged. Three tractors were also damaged. One of the tractors was hooked up to a hay baler and was moved 100 yards. This was the first of three tornadic events in two days for Oklahoma. The other two events occurred on the afternoon of May 8 and on May 9, 2003 (see appropriate storm data). The five tornadoes that occurred in south central Oklahoma all happened after midnight with the strongest tornadoes producing F2 damage. One large supercell produced the three strongest tornadoes of the night.

 Brief Description: A major severe weather outbreak occurred across western and central Oklahoma from the afternoon of the 4th through the early morning of the 5th, resulting in 19 tornadoes, straight-line wind damage, hail as large as baseballs, and significant flooding across portions of Lincoln and Noble Counties, where numerous costly bridges were destroyed. Thunderstorms first developed over northwest Oklahoma during the early and mid-afternoon where hail larger than golf balls was reported in Major and Woodward Counties. The first of 19 tornadoes occurred at 1425 CST in Woods County 11 miles south-southwest of Dacoma. A media storm chaser observed this multiple vortex tornado as it touched down in southeastern Woods County and traveled northeast into western Alfalfa County before dissipating 4 miles northwest of Carmen. Damage was first reported south of Dacoma where an old abandoned house was damaged and a barn and garage were destroyed. As the tornado moved into western Alfalfa County, an office building at Carmen Field Limited Partnership and a local gas plant were completely destroyed. A modular home adjacent to the gas plant also had most of its roof blown off. Numerous witnesses described this tornado (F2) as very large and was at least a quarter of a mile wide. The 2nd tornado, an F0, developed on the salt flats 5 miles southeast of Cherokee in Alfalfa County and was seen by an Alfalfa County Sheriff's Deputy. The 3rd tornado was witnessed by a state trooper touching down very close to Highway 11, 5 miles west of Medford in Grant County, and was on the ground for less than one minute with no known damage (F0). As the thunderstorms associated with these tornadoes moved east, additional thunderstorms began to intensify farther south. Near Mountain Park in Kiowa County, Baseball size hail destroyed numerous car windshields. A short while longer, at 1638 CST, the 4th tornado was captured on video by a reliable storm chaser 9 miles southwest of Watonga in Blaine County. This tornado touched down for only a few seconds in an open field with no known damage (F0). Several storage buildings at a Lowe's Department Store in Ponca City in Kay County, were blown over by winds estimated between 80-90 mph. The 5th tornado touched down 2.5 miles southwest of Watonga in Blaine County and crossed US-270/281 two miles south of Watonga. The tornado continued to the northeast and finally dissipated about 9 miles east-northeast of Watonga. At least three homes suffered significant damage, one of which had its roof completely removed (F2). The 6th tornado was seen by an Oklahoma Highway Patrol Officer 5 miles north of Medicine Park in Comanche County touching down briefly in an open field with no known damage (F0). The 7th tornado, an F1, touched down 6 miles southwest of Dover in Kingfisher County and traveled northeast for 7 miles, crossing Highway 81 near the Cimarron River, and dissipating 2 miles southeast of Dover. One haybarn was destroyed, while 1 residence and 5 barns were damaged. Numerous trees and power lines were also downed. The 8th tornado, an F0, touched down just west of the intersection of US-277 and SH-8, 1 mile north of Cyril in Caddo County, and moved east for one-half mile knocking down trees and power lines and causing minor roof damage in the extreme northeastern portion of Cyril. While straight-line winds damaged a roof at the Farmers Coop Association building, and a trailer home in Guthrie in Logan County at 1745 CST, the 9th tornado touched down at 1747 CST on or just south of Lake Carl Blackwell in Payne County, and was observed by numerous people in and near Stillwater. The tornado moved northeast over the lake, crossed into extreme southern Noble County, and over Lake McMurtry. Minor damage was reported in northern Payne County, however the worst damage occurred in southern Noble County as the tornado moved off of Lake McMurtry and severely damaged a mobile home (F1). The 10th tornado (F2) was witnessed by 3 firefighters 1 mile south of Highway 277 on Lake Burtshi Road 9 miles west-southwest of Ninnekah in Grady County, and was on the ground for 1.5 miles. One mobile home was disintegrated, while 2 others nearby were flipped over. Many well-structured homes sustained minor roof damage, and numerous trees were blown over, some onto homes and one onto an RV. A storage building was also destroyed. The 11th tornado, also an F2, touched down in Grady County, 4.5 miles north of Middleburg, damaging several mobile homes and outbuildings. One mobile home was completely destroyed in the Bridge Creek area while two others were blown over. Scattered tree damage continued for 5 miles into McClain county just to the southwest of the Newcastle city limits. Wind damage continued into the south part of Newcastle causing damage to trees and power lines. In addition to the tornado damage, straight-line winds overturned several tractor-trailers 7 miles south of Tuttle, also in Grady County, and destroyed a barn in Dibble in McClain County. Lightning also struck a house on Broadway in Norman in Cleveland County, causing a small fire at 1900 CST. The 12th tornado (F0) developed at 1926 CST 3 miles north of Newcastle in McClain County, and was observed by people from Norman, Moore and Newcastle. This tornado touched down just northeast of the intersection of I-44 and North 32nd Street north of Newcastle, and moved north into extreme western Cleveland County near SW 149th St. and Meridian Avenue, in southwest Oklahoma City. Damage was primarily to trees. The 13th tornado was one of the most destructive tornadoes of the outbreak, developing over the city of Moore in Cleveland County about 1/2 mile north of SW 19th Ave, just east of Santa Fe Ave. The tornado tracked almost due north at first, and then curved slightly east of north. Many homes lost all or parts of their roofs, leaving them uninhabitable, and one home lost a portion of an exterior wall. Sections of roofs were also torn off of a few warehouses as the tornado crossed Shields Ave. and then dissipated just west of I-35. The worst damage occurred along NW 12th Ave to the west of Janaway where F2 damage was observed. In total, 10 single-family residences were either destroyed or severely damaged; 8 multi-family buildings were severely damaged; and hundreds of other homes and businesses sustained minor damage. Damage estimates were near 2 million dollars. The 14th tornado touched down near EW 106 road and NS 346 Road 4 miles southeast of Meeker in Lincoln County, where light damage occurred to many trees. The tornado then moved northeast crossing EW 347 south of US 62. Damage was observed from just south of this intersection southward for about one mile. Just south of the intersection, trees were downed and a house received damage to the roof and porch. F2 damage occurred about 1/2 mile south of US 62, where three homes received significant roof damage, and an RV was pushed over onto its side. The tornado crossed US 62 with light damage to trees and minor damage to a house along the highway. The tornado likely dissipated just northeast of the intersection of US 62 and NS 347 Road. The 15th tornado, also an F2, developed a few minutes after the last tornado about 7 miles west of Prague. This tornado touched down near NS 348 road about 1/2 mile north of EW 106 Road where a mobile home received light damage. The tornado moved northeast crossing near the intersection of EW 105 Road and NS 349 Road, then grew in size and intensity before crossing US 62. A mobile home along US 62 just west of NS 350 Road was destroyed. The metal frame that supported the home and most of the contents was deposited northwest of the original location up to 150 yards. Other debris was thrown north-northeast across US 62. The tornado then continued northeast and damage was noted for 3/4 of a mile along NS 350 Road centered on US 62. Slight damage to trees and outbuildings was observed along NS 352 Road approximately 2 miles north of US 62. The tornado probably dissipated northeast of this point, although roads became inaccessibe due to flooding and made it difficult to determine the exact location. In addition, a 6 mile long swath of damaging straight-line winds accompanied this tornado from 6 miles west of Prague to 3 miles northwest of Prague, resulting in massive tree damage. Damaging straight-line winds were also responsible for blowing down trees and power lines in Shawnee in Pottowatomie County at 2010 CST, and for a wind gust of 64 mph at 2020 CST, 4 miles west-southwest of Guthrie in Logan County, measured by Oklahoma Mesonet. Another tornado, the 16th of the outbreak, developed at about the same time 6 miles northwest of Prague, and moved northeast for 7 miles before dissipating 7 miles north-northeast of Prague. This tornado, rated an F1, touched down at the intersection of EW 102 Road and NS 350 Road where outbuildings received moderate damage. Less than 1/4 of a mile away on EW 102 Road, a mobile home was lifted and thrown east about 100 yards, uprooting a power pole while airborne. The mobile home was destroyed upon impact. All 6 family members who took shelter inside an interior closet were injured. All injuries were minor, except for the father who suffered broken ribs, a cracked pelvis and head injuries. He stayed overnight in a nearby hospital and was released the next day. As the tornado continued east-northeast along NS 352 Road, south of the community of Wilzetta, an outbuilding was unroofed, minor damage occurred to a house roof, and trees were uprooted. Tree and power line damage continued to about 2 or 3 miles east of Wilzetta. The tornado then turned more to the northeast as it crossed SH 99 where a mobile home received minor damage, 3 outbuildings were destroyed, a few logs at a sawmill were tossed, and trees were downed. Scattered tree damage was observed to just southwest of the intersection of NS 357 Road and EW 99 Road where the tornado lifted. In addition to the tornadoes near Prague, straight-line winds were responsible for downing numerous trees and awnings of several businesses in downtown Prague. Farther south in Pottawatomie County, 2 tornadoes (Numbers 17 and 18 of the outbreak) embedded in larger swaths of damaging straight-line winds, developed near Shawnee. The first one touched down 3 miles northwest of Shawnee and remained on the ground for 3 miles before dissipating 3 miles north of Shawnee. A large swath of damaging straight-line winds approximately 1 mile wide and 4 miles long accompanied this F1 tornado as it moved across northern portions of Shawnee. Extensive tree damage occurred on a private golf course just west of Acme road. Minor damage also occurred to the roof of the clubhouse and to the roof-mounted air conditioning unit. Widespread tree and roof damage also occurred in a subdivision south of 45th St. and west of Kickapoo. In addition to a mobile home being destroyed near the east end of the damage path, which is believed to be the result of a tornado, many other mobile homes nearby received minor damage. In addition, 1 mile southeast of Dale in Pottowatomie County, numerous trees and signs were either destroyed or uprooted along Interstate 40; a shed was destroyed, and a barn was unroofed along Highway 102. Oklahoma Mesonet also measured a wind gust of 72 mph at 2055 CST, 3 miles north-northwest of Shawnee. The 2nd tornado, also an F1 and the 18th tornado of the outbreak, developed in or very close to the Shawnee business district, moved east for 2 miles, and was also accompanied by a large area of damaging straight-line winds. The exact damage resulting from the tornado was difficult to assess, but it is believed it was limited to fallen trees, downed power lines, and minor roof and structural damage to many homes. The area of straight-line wind damage was approximately 2.5 miles wide and 5 miles long, and occurred from the western side of Shawnee to the eastern side of Shawnee. Damage included widespread fallen trees in a suburban area north of Highland extending several blocks either side of Kickapoo, in the Woodland Park area, Boy Scout Park, and in the rural area along and south of Farrel Road between Harrison and Bryan. One tree fell on and heavily damaged the Beard House, a local landmark that was the first homestead built in Shawnee in 1895. An east-facing cinder block wall of a warehouse was blown outward in the vicinty of Minnesota and Pennsylvania Streets, and structural damage occurred to many buildings in downtown Shawnee, including toppled brick walls and broken windows. The combination of widespread straight-line wind damage and a tornado resulted in major damage over a very large area. The 19th and last tornado of the outbreak touched down 5 miles west-northwest of Little, near the intersection of EW 114 Road and NS 351 Road in northwestern Pottowatomie County, where minor tree damage was observed. The tornado, an F3, then increased in size to approximately a 1/2 mile wide as it moved northeast. As it crossed NS 351 Road and then EW 113 Road, a number of outbuildings were heavily damaged, and trees were snapped. Three mobile homes received light damage near the north edge of the path, and 3 other homes received light damage to shingles. The tornado crossed Interstate 40 blowing over a truck which was carrying hazardous materials. The tornado then continued northeast unroofing a mobile home, causing damage to trees and destroying a number of outbuilding before crossing the North Canadian River into northeast Pottawatomie County. Along EW 110 Road, significant tree damage was observed, and a barn was partially unroofed. The community of Center View near the intersection of SH 99 and EW 109 Road was then hard hit with most of the damage south and east of this intersection. From the debris pattern, the center of the tornado crossed Highway 99 one-half mile south of EW 109 Road. A house along Highway 99 was unroofed and lost most of its exterior walls. Three homes suffered major damage along EW 109 Road. Two other homes suffered significant damage. As the tornado continued moving northeast another home suffered significant roof damage, and the south facing brick wall was buckled. The garage was destroyed. Steel and cinder block from the garage were impaled in a tree. There was also significant damage to large trees. Farther northeast, damage to a roof was noted, and a large number of power lines were downed along NS 357 Road near the intersection of EW 108 Road. One outbuilding was damaged, and light damage was observed in trees just south of EW 107 Road. In total, at least 60 homes or businesses were damaged. Major flooding developed across Noble, Lincoln, and Payne Counties shortly after midnight on the 5th. Red Rock Creek and Black Bear Creek near Red Rock in Payne County, overflowed their banks between Highway 77 and Interstate 35 washing away several small bridges. Damage was estimated at 200 thousand dollars. Six to seven inches of rain fell across a large portion of Lincoln County. At least 3 bridges were washed away by the floods including 1 bridge 1 mile east of Kendrick, and dozens of roads suffered erosion damage. Creeks also overflowed their banks in Stroud, Davenport, and Agra. At least 500 thousand dollars in damage resulted. Between 4 and 5 inches of rain fell across Payne County forcing the Cu Chee Creek to overflow its banks, flooding many roads in Cushing and Stillwater.

 Brief Description: A major severe weather outbreak occurred across western and central Oklahoma from the afternoon of the 4th through the early morning of the 5th, resulting in 19 tornadoes, straight-line wind damage, hail as large as baseballs, and significant flooding across portions of Lincoln and Noble Counties, where numerous costly bridges were destroyed. Thunderstorms first developed over northwest Oklahoma during the early and mid-afternoon where hail larger than golf balls was reported in Major and Woodward Counties. The first of 19 tornadoes occurred at 1425 CST in Woods County 11 miles south-southwest of Dacoma. A media storm chaser observed this multiple vortex tornado as it touched down in southeastern Woods County and traveled northeast into western Alfalfa County before dissipating 4 miles northwest of Carmen. Damage was first reported south of Dacoma where an old abandoned house was damaged and a barn and garage were destroyed. As the tornado moved into western Alfalfa County, an office building at Carmen Field Limited Partnership and a local gas plant were completely destroyed. A modular home adjacent to the gas plant also had most of its roof blown off. Numerous witnesses described this tornado (F2) as very large and was at least a quarter of a mile wide. The 2nd tornado, an F0, developed on the salt flats 5 miles southeast of Cherokee in Alfalfa County and was seen by an Alfalfa County Sheriff's Deputy. The 3rd tornado was witnessed by a state trooper touching down very close to Highway 11, 5 miles west of Medford in Grant County, and was on the ground for less than one minute with no known damage (F0). As the thunderstorms associated with these tornadoes moved east, additional thunderstorms began to intensify farther south. Near Mountain Park in Kiowa County, Baseball size hail destroyed numerous car windshields. A short while longer, at 1638 CST, the 4th tornado was captured on video by a reliable storm chaser 9 miles southwest of Watonga in Blaine County. This tornado touched down for only a few seconds in an open field with no known damage (F0). Several storage buildings at a Lowe's Department Store in Ponca City in Kay County, were blown over by winds estimated between 80-90 mph. The 5th tornado touched down 2.5 miles southwest of Watonga in Blaine County and crossed US-270/281 two miles south of Watonga. The tornado continued to the northeast and finally dissipated about 9 miles east-northeast of Watonga. At least three homes suffered significant damage, one of which had its roof completely removed (F2). The 6th tornado was seen by an Oklahoma Highway Patrol Officer 5 miles north of Medicine Park in Comanche County touching down briefly in an open field with no known damage (F0). The 7th tornado, an F1, touched down 6 miles southwest of Dover in Kingfisher County and traveled northeast for 7 miles, crossing Highway 81 near the Cimarron River, and dissipating 2 miles southeast of Dover. One haybarn was destroyed, while 1 residence and 5 barns were damaged. Numerous trees and power lines were also downed. The 8th tornado, an F0, touched down just west of the intersection of US-277 and SH-8, 1 mile north of Cyril in Caddo County, and moved east for one-half mile knocking down trees and power lines and causing minor roof damage in the extreme northeastern portion of Cyril. While straight-line winds damaged a roof at the Farmers Coop Association building, and a trailer home in Guthrie in Logan County at 1745 CST, the 9th tornado touched down at 1747 CST on or just south of Lake Carl Blackwell in Payne County, and was observed by numerous people in and near Stillwater. The tornado moved northeast over the lake, crossed into extreme southern Noble County, and over Lake McMurtry. Minor damage was reported in northern Payne County, however the worst damage occurred in southern Noble County as the tornado moved off of Lake McMurtry and severely damaged a mobile home (F1). The 10th tornado (F2) was witnessed by 3 firefighters 1 mile south of Highway 277 on Lake Burtshi Road 9 miles west-southwest of Ninnekah in Grady County, and was on the ground for 1.5 miles. One mobile home was disintegrated, while 2 others nearby were flipped over. Many well-structured homes sustained minor roof damage, and numerous trees were blown over, some onto homes and one onto an RV. A storage building was also destroyed. The 11th tornado, also an F2, touched down in Grady County, 4.5 miles north of Middleburg, damaging several mobile homes and outbuildings. One mobile home was completely destroyed in the Bridge Creek area while two others were blown over. Scattered tree damage continued for 5 miles into McClain county just to the southwest of the Newcastle city limits. Wind damage continued into the south part of Newcastle causing damage to trees and power lines. In addition to the tornado damage, straight-line winds overturned several tractor-trailers 7 miles south of Tuttle, also in Grady County, and destroyed a barn in Dibble in McClain County. Lightning also struck a house on Broadway in Norman in Cleveland County, causing a small fire at 1900 CST. The 12th tornado (F0) developed at 1926 CST 3 miles north of Newcastle in McClain County, and was observed by people from Norman, Moore and Newcastle. This tornado touched down just northeast of the intersection of I-44 and North 32nd Street north of Newcastle, and moved north into extreme western Cleveland County near SW 149th St. and Meridian Avenue, in southwest Oklahoma City. Damage was primarily to trees. The 13th tornado was one of the most destructive tornadoes of the outbreak, developing over the city of Moore in Cleveland County about 1/2 mile north of SW 19th Ave, just east of Santa Fe Ave. The tornado tracked almost due north at first, and then curved slightly east of north. Many homes lost all or parts of their roofs, leaving them uninhabitable, and one home lost a portion of an exterior wall. Sections of roofs were also torn off of a few warehouses as the tornado crossed Shields Ave. and then dissipated just west of I-35. The worst damage occurred along NW 12th Ave to the west of Janaway where F2 damage was observed. In total, 10 single-family residences were either destroyed or severely damaged; 8 multi-family buildings were severely damaged; and hundreds of other homes and businesses sustained minor damage. Damage estimates were near 2 million dollars. The 14th tornado touched down near EW 106 road and NS 346 Road 4 miles southeast of Meeker in Lincoln County, where light damage occurred to many trees. The tornado then moved northeast crossing EW 347 south of US 62. Damage was observed from just south of this intersection southward for about one mile. Just south of the intersection, trees were downed and a house received damage to the roof and porch. F2 damage occurred about 1/2 mile south of US 62, where three homes received significant roof damage, and an RV was pushed over onto its side. The tornado crossed US 62 with light damage to trees and minor damage to a house along the highway. The tornado likely dissipated just northeast of the intersection of US 62 and NS 347 Road. The 15th tornado, also an F2, developed a few minutes after the last tornado about 7 miles west of Prague. This tornado touched down near NS 348 road about 1/2 mile north of EW 106 Road where a mobile home received light damage. The tornado moved northeast crossing near the intersection of EW 105 Road and NS 349 Road, then grew in size and intensity before crossing US 62. A mobile home along US 62 just west of NS 350 Road was destroyed. The metal frame that supported the home and most of the contents was deposited northwest of the original location up to 150 yards. Other debris was thrown north-northeast across US 62. The tornado then continued northeast and damage was noted for 3/4 of a mile along NS 350 Road centered on US 62. Slight damage to trees and outbuildings was observed along NS 352 Road approximately 2 miles north of US 62. The tornado probably dissipated northeast of this point, although roads became inaccessibe due to flooding and made it difficult to determine the exact location. In addition, a 6 mile long swath of damaging straight-line winds accompanied this tornado from 6 miles west of Prague to 3 miles northwest of Prague, resulting in massive tree damage. Damaging straight-line winds were also responsible for blowing down trees and power lines in Shawnee in Pottowatomie County at 2010 CST, and for a wind gust of 64 mph at 2020 CST, 4 miles west-southwest of Guthrie in Logan County, measured by Oklahoma Mesonet. Another tornado, the 16th of the outbreak, developed at about the same time 6 miles northwest of Prague, and moved northeast for 7 miles before dissipating 7 miles north-northeast of Prague. This tornado, rated an F1, touched down at the intersection of EW 102 Road and NS 350 Road where outbuildings received moderate damage. Less than 1/4 of a mile away on EW 102 Road, a mobile home was lifted and thrown east about 100 yards, uprooting a power pole while airborne. The mobile home was destroyed upon impact. All 6 family members who took shelter inside an interior closet were injured. All injuries were minor, except for the father who suffered broken ribs, a cracked pelvis and head injuries. He stayed overnight in a nearby hospital and was released the next day. As the tornado continued east-northeast along NS 352 Road, south of the community of Wilzetta, an outbuilding was unroofed, minor damage occurred to a house roof, and trees were uprooted. Tree and power line damage continued to about 2 or 3 miles east of Wilzetta. The tornado then turned more to the northeast as it crossed SH 99 where a mobile home received minor damage, 3 outbuildings were destroyed, a few logs at a sawmill were tossed, and trees were downed. Scattered tree damage was observed to just southwest of the intersection of NS 357 Road and EW 99 Road where the tornado lifted. In addition to the tornadoes near Prague, straight-line winds were responsible for downing numerous trees and awnings of several businesses in downtown Prague. Farther south in Pottawatomie County, 2 tornadoes (Numbers 17 and 18 of the outbreak) embedded in larger swaths of damaging straight-line winds, developed near Shawnee. The first one touched down 3 miles northwest of Shawnee and remained on the ground for 3 miles before dissipating 3 miles north of Shawnee. A large swath of damaging straight-line winds approximately 1 mile wide and 4 miles long accompanied this F1 tornado as it moved across northern portions of Shawnee. Extensive tree damage occurred on a private golf course just west of Acme road. Minor damage also occurred to the roof of the clubhouse and to the roof-mounted air conditioning unit. Widespread tree and roof damage also occurred in a subdivision south of 45th St. and west of Kickapoo. In addition to a mobile home being destroyed near the east end of the damage path, which is believed to be the result of a tornado, many other mobile homes nearby received minor damage. In addition, 1 mile southeast of Dale in Pottowatomie County, numerous trees and signs were either destroyed or uprooted along Interstate 40; a shed was destroyed, and a barn was unroofed along Highway 102. Oklahoma Mesonet also measured a wind gust of 72 mph at 2055 CST, 3 miles north-northwest of Shawnee. The 2nd tornado, also an F1 and the 18th tornado of the outbreak, developed in or very close to the Shawnee business district, moved east for 2 miles, and was also accompanied by a large area of damaging straight-line winds. The exact damage resulting from the tornado was difficult to assess, but it is believed it was limited to fallen trees, downed power lines, and minor roof and structural damage to many homes. The area of straight-line wind damage was approximately 2.5 miles wide and 5 miles long, and occurred from the western side of Shawnee to the eastern side of Shawnee. Damage included widespread fallen trees in a suburban area north of Highland extending several blocks either side of Kickapoo, in the Woodland Park area, Boy Scout Park, and in the rural area along and south of Farrel Road between Harrison and Bryan. One tree fell on and heavily damaged the Beard House, a local landmark that was the first homestead built in Shawnee in 1895. An east-facing cinder block wall of a warehouse was blown outward in the vicinty of Minnesota and Pennsylvania Streets, and structural damage occurred to many buildings in downtown Shawnee, including toppled brick walls and broken windows. The combination of widespread straight-line wind damage and a tornado resulted in major damage over a very large area. The 19th and last tornado of the outbreak touched down 5 miles west-northwest of Little, near the intersection of EW 114 Road and NS 351 Road in northwestern Pottowatomie County, where minor tree damage was observed. The tornado, an F3, then increased in size to approximately a 1/2 mile wide as it moved northeast. As it crossed NS 351 Road and then EW 113 Road, a number of outbuildings were heavily damaged, and trees were snapped. Three mobile homes received light damage near the north edge of the path, and 3 other homes received light damage to shingles. The tornado crossed Interstate 40 blowing over a truck which was carrying hazardous materials. The tornado then continued northeast unroofing a mobile home, causing damage to trees and destroying a number of outbuilding before crossing the North Canadian River into northeast Pottawatomie County. Along EW 110 Road, significant tree damage was observed, and a barn was partially unroofed. The community of Center View near the intersection of SH 99 and EW 109 Road was then hard hit with most of the damage south and east of this intersection. From the debris pattern, the center of the tornado crossed Highway 99 one-half mile south of EW 109 Road. A house along Highway 99 was unroofed and lost most of its exterior walls. Three homes suffered major damage along EW 109 Road. Two other homes suffered significant damage. As the tornado continued moving northeast another home suffered significant roof damage, and the south facing brick wall was buckled. The garage was destroyed. Steel and cinder block from the garage were impaled in a tree. There was also significant damage to large trees. Farther northeast, damage to a roof was noted, and a large number of power lines were downed along NS 357 Road near the intersection of EW 108 Road. One outbuilding was damaged, and light damage was observed in trees just south of EW 107 Road. In total, at least 60 homes or businesses were damaged. Major flooding developed across Noble, Lincoln, and Payne Counties shortly after midnight on the 5th. Red Rock Creek and Black Bear Creek near Red Rock in Payne County, overflowed their banks between Highway 77 and Interstate 35 washing away several small bridges. Damage was estimated at 200 thousand dollars. Six to seven inches of rain fell across a large portion of Lincoln County. At least 3 bridges were washed away by the floods including 1 bridge 1 mile east of Kendrick, and dozens of roads suffered erosion damage. Creeks also overflowed their banks in Stroud, Davenport, and Agra. At least 500 thousand dollars in damage resulted. Between 4 and 5 inches of rain fell across Payne County forcing the Cu Chee Creek to overflow its banks, flooding many roads in Cushing and Stillwater.
