| Brief Description: An F2 tornado destroyed one single family dwelling, while another single family dwelling received major damage. Summary of events for the evening of June 8 and the early morning of June 9 1998: A classic southern plains severe weather event shaped up on the afternoon and evening of June 8 as a number of isolated severe thunderstorms developed over central Oklahoma to the east of a dryline. The first severe thunderstorm to affect eastern Oklahoma scraped the northwestern part of Osage County, causing a report of a severe thunderstorm gust. This storm quickly died as it entered Kansas. A second more serious severe thunderstorm formed west of Oklahoma City and tracked all the way to the Arkansas state line south of Fort Smith, traversing Pittsburg, Haskell, and Le Flore Counties. This storm travelled east along an instability axis and a warm front. From a radar perspective, this storm was impressive in that it kept a classic, well-defined hook on its entire journey across southeast Oklahoma. From a human perspective, this storm was impressive in that it produced ten tornadoes in southeast Oklahoma, hail as large as golfballs, damaging thunderstorm winds, and torrential flooding rains. A third cluster of severe thunderstorms developed over Creek County and moved east across Okmulgee, Muskogee, Cherokee, and Adair Counties before weakening as it entered Arkansas. These storms slowed their movement across Muskogee County and regeneration along the southwest flank of the storms caused torrential rainfalls that dumped nearly three inches of rain in northern Muskogee, southern Cherokee, southern Adair, and northern Sequoyah Counties. In addition to flooding rains, these storms produced hail as large as nickels and damaging thunderstorm winds. | |||||||||||

| Brief Description: EVENT NARRATIVE: This tornado continued from Pittsburg County. As it moved into Latimer County, the tornado destroyed a double-wide mobile home, severely damaged another home and barn, and rolled an F350 pickup truck about 50 yards. Numerous trees were snapped or uprooted as the tornado approached Yanush. In Yanush, about 50 homes were damaged, eight of those were destroyed along with one business. Numerous sheds, barns, and outbuildings were destroyed. Numerous trees and power lines were blown down. EPISODE NARRATIVE: Elevated severe thunderstorms containing large hail developed north of a warm front that was moving slowly northward across eastern Oklahoma and west central Arkansas during the morning and early afternoon of the 10th. Another round of severe thunderstorms developed late in the afternoon as a dry line approached the area from the west. Extreme instability and strong vertical wind shear resulted in the development of long-lived supercell thunderstorms that moved across eastern Oklahoma and northwestern Arkansas during the late afternoon and evening. Several of these supercells became tornadic and a few produced long-lived damaging tornadoes. One such supercell developed and moved along the Oklahoma-Kansas border and then into southwestern Missouri. This storm produced a tornado in northeastern Craig County OK that remained on the ground for 29 miles in Oklahoma, continued for about 31 miles in Newton County MO, and finally dissipated about 15 miles into Barry County MO. It produced EF-4 damage in several locations, including Picher, a small town in north-central Ottawa County OK. Twenty-one fatalities, over 350 injuries, and an estimated $60 million in property damage resulted from this tornado in Oklahoma and Missouri. Six of the fatalities and about 150 injuries occurred in Picher OK. Other strong tornadoes developed and moved across portions of Pittsburg and Latimer Counties. A EF-2 tornado was on the ground for about eight miles west of McAlester, damaging numerous homes in its path. Another EF-2 tornado developed southwest of Hartshorne in Pittsburg County and moved 19 miles before dissipating just east of Yanush in Latimer County. Four injuries resulted from that tornado and numerous homes were severely damaged or destroyed. | |||||||||||

| Brief Description: An F2 tornado touched down in Polk County and traveled approximately 20 miles before it lifted. Even though the tornado was not on the ground continuously, it still managed to cause extensive damage to several towns along its path. The tornado initially touched down approximately 2.50 miles west of Cove, along Highway 4. The storm passed through Cove where it damaged and destroyed several homes and businesses. The tornado then struck the Hatfield area where it destroyed or damaged a number of homes. The tornado continued moving northeastward and struck the southwest part of Mena. In Mena, a large number of homes and businesses sustained damage. Most of the buildings that were struck were either destroyed or received major damage. Eleven people in Mena were treated for minor injuries. A local park in Mena lost a number of large trees. Some of these trees were over 100 years old. A number of buildings in Mena were damaged as a result of trees falling on the structures. The tornado finally lifted about three miles northeast of Mena, in the community of Hillcrest, where it destroyed a few mobile homes and damaged several others. Initial estimates placed the damage at over $6 million. | |||||||||||

| Brief Description: EVENT NARRATIVE: A tornado began to the west-southwest of Mena, then tracked through the northwest side of Mena. According to the Polk County Judge, 165 houses were destroyed, 701 houses had major damage, and more than 11,000 trees were blown down. The Polk County Courthouse, county jail, Mena City Hall, and the police and fire departments were damaged in downtown Mena, as were several businesses. Mena Middle School, also located downtown, was structurally damaged beyond repair. A nursing home was also damaged. Most of the city lost electricity. The tornado then tracked to the northeast, badly damaging several industrial buildings. There was considerable roof damage at Rich Mountain Community College, and lesser damage to the hospital. As the tornado continued to the northeast, a tractor dealership was destroyed. A number of rural residences and farms were damaged as the tornado moved out into rural Polk County. North of Ink, damage was noted along Polk 74 and Polk 71; these same areas had been damaged by a tornado on October 6, 2008. Three fatalities occurred on the northwest side of Mena. One was a woman at a Masonic Lodge, and the others were a man and woman at separate residences. EPISODE NARRATIVE: Low pressure aloft approached from the west and collided with moisture and instability. Thunderstorms developed in eastern Oklahoma during the afternoon, then became more numerous as they entered western Arkansas during the evening. The storms brought a few tornadoes and numerous hailstorms to Arkansas during the evening hours. | |||||||||||

| Brief Description: EVENT NARRATIVE: The tornado continued into Pushmataha county before lifting 2.75 miles WSW of Adel. In Atoka County, three houses were damaged. The roof was removed and some of the exterior walls on one well-built home were collapsed. Numerous trees were uprooted or snapped above the ground. Monetary damage were estimated. EPISODE NARRATIVE: A powerful storm system strengthened over the central Plains during the day on Saturday, drawing rich gulf moisture north into eastern Oklahoma. A surface low pressure developed with a trailing cold front that moved quickly through western Oklahoma, and a dry line extending to the east of the cold front. Isolated severe thunderstorms developed near Hughes county early in the afternoon, with large hail reported in a few locations. Later in the afternoon, supercells over eastern Oklahoma expanded southwest. One supercell developed over far eastern Atoka county, producing a tornado near Daisy and large hail. Damage was reported with the tornado, but there were no injuries. Monetary damages were estimated. | |||||||||||

| Brief Description: The F3 tornado described here was the second of two tornadoes to touch down in the Checotah area on the evening of June 1. Both tornadoes were spawned from the same parent thunderstorm. Even though this tornado had a stronger F-rating than the first, it caused less widespread damage since it travelled through a less densely populated area. The second tornado touched down on the southeast side of Checotah near I-40 and Grapevine Road at 650 PM CDT. The tornado travelled southeast for 4.5 miles and then lifted at 706 PM CDT. Damage assessments in Checotah combined the effects of the first and second tornadoes. For details of the damage assessment, see the third paragraph of the narrative for the Tornado entry immediately preceding this entry. This tornado, the second of the two, was rated an F3 based based on the near-complete destruction of a farm house 3 to 4 miles southeast of Checotah. Summary of events for the afternoon and evening of June 1 1999: A cold front moving in from the northwest moved into an extremely unstable air mass on the afternoon of June 1. Along the front, an isolated supercell thunderstorm developed around the Pryor/Locust Grove area and then moved in a slow and unusual south-southwest direction. This storm produced very large hail in addition to several strong tornadoes. This storm also produced eastern Oklahoma's first killer tornado in at least half of a decade. | |||||||||||
