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

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: A significant long-track tornado first touched down in Sequoyah County 4 miles west of Short, travelling northeast for 39 miles to a point about 7 miles southwest of Fayetteville, AR. This tornado eventually reached its peak as an F3 tornado in extreme southeast Adair County. In Sequoyah County, this tornado travelled across a sparsely-populated part of the county, causing mostly tree damage. Property damage listed with this entry is just for the portion of the tornado in Sequoyah County, while the F-rating reflects the peak strength of the tornado in Adair County. Summary of events for May 3-4 1999: Following a week-long blocking weather pattern, a strong upper level trough finally moved out of the southwestern U.S. Interactions with a dryline in western Oklahoma and a slow-moving cold front brought the largest tornado outbreak in Oklahoma history from the afternoon of May 3 through the afternoon of May 4. Most notable was the F5 tornado that moved through southern parts of the Oklahoma City metro area. While the loss of life and the heaviest property damage was limited to central Oklahoma, eastern Oklahoma got into the act with a significant number of tornadoes. While there were dozens of individual storms on May 3 and 4, there are two storms in eastern Oklahoma that stand out as outstanding. The first outstanding storm moved northeast along the I-44 corridor on the evening of May 3, causing F3 damage to Stroud in Lincoln County. The storm went on to cause significant F1 damage in Sapulpa and southwestern portions of the city of Tulsa and millions of dollars in damage. The second outstanding storm got its start in southeast Oklahoma well south of McAlester. This storm moved northeast across Pushmataha, Latimer, Haskell, LeFlore and Sequoyah Counties, producing several damaging tornadoes along the way. The final tornado touched down in Sequoyah County and tracked 39 miles to near Fayetteville, AR, producing F3 damage in an unpopulated forest in Adair County. Following a very wet April that saturated area grounds, another slow-moving weather system made flash flooding another serious problem to deal with as most rainfall quickly ran off into creeks, streams and mainstem rivers. One flash flood in Vinita caused millions of dollars in damage following the flooding of dozens of homes. | |||||||||||
