		Brief Description: EVENT NARRATIVE: This segment is the first of six segments of this long-track tornado. A tornado developed just northeast of Westville and moved rapidly northeastward damaging a home, tossing or rolling four vehicles, snapping at least 13 large power poles, and snapping or uprooting large trees. Estimated maximum wind based on this damage was 125 mph. This tornado continued into Washington County, Arkansas. EPISODE NARRATIVE: Unseasonably warm and moist air spread into eastern Oklahoma ahead of a cold front. Scattered thunderstorms developed in the late evening and early morning hours ahead of the cold front as a weak upper level disturbance passed through the region. Large hail and damaging wind gusts occurred with some of these storms. Another round of storms developed on the cold front as it moved into eastern Oklahoma a few hours before sunrise. Weak to moderate instability combined with very strong low level wind shear created an environment that supported supercell thunderstorm structures. Several supercells developed resulting in large hail and damaging wind gusts in the hours just before and after sunrise on the 31st. One of these supercells produced a long-track, strong tornado that began in Adair County, Oklahoma, and moved into Washington County, Arkansas, where it killed four people in and near the town of Cincinnati.

		Brief Description: EVENT NARRATIVE: This segment is the second of six segments of this long-track tornado. The tornado moved into Washington County snapping numerous trees as it approached the town of Cincinnati. In Cincinnati, the tornado destroyed several permanent homes, destroyed the volunteer fire station, destroyed a mobile home, damaged several other permanent homes, snapped or uprooted numerous trees, snapped numerous power poles, and destroyed barns and outbuildings. Two people were killed in the mobile home that was destroyed and a third person was killed either in or near a barn while he was tending to his cattle. At least seven injuries also occurred. The tornado was about 300 yards wide when it went through town. The maximum estimated wind speed in the tornado based on this damage was 140 mph. The tornado continued to move rapidly northeastward and widened to about 500 yards northeast of Cincinnati. Several permanent homes were severely damaged, several mobile homes were destroyed, at least four chicken houses were destroyed, outbuildings were destroyed, numerous trees were snapped or uprooted, and power poles were snapped. A woman in one of the mobile homes that was destroyed was transported to a hospital with serious injuries. She later died from those injuries on January 4th. The tornado continued into Benton County, Arkansas. EPISODE NARRATIVE: Unseasonably warm and moist air spread into northwestern Arkansas ahead of a cold front. Scattered thunderstorms developed in the late evening and early morning hours ahead of the cold front as a weak upper level disturbance passed through the region. Large hail and damaging wind gusts occurred with some of those storms. Another round of storms developed on the cold front over eastern Oklahoma as it pushed into the area. Weak to moderate instability combined with very strong low level wind shear created an environment that supported supercell thunderstorm structures. Several supercells developed resulting in large hail and damaging wind gusts in the hours just before and after sunrise on the 31st. One of these supercells produced a long-track, strong tornado that killed four people in and near the town of Cincinnati in Washington County. Debris was transported by the tornado into northern Benton County and was reported in Bella Vista and Pea Ridge. The Northwest Arkansas Regional Airport (XNA) was closed for three hours to remove the debris from the flight line. Another supercell produced a short-lived, weak tornado in Carroll County that moved into Missouri.

		Brief Description: A strong tornado, rated an F3, touched down in far western Cherokee County, possibly as a waterspout on Fort Gibson Lake. The tornado moved south onshore and through the rural Amber Hills housing area, crossing OK Hwy 51, and lifting after tracking through much of the Sequoyah State Park. In the Amber Hills and Hammer Hill Road areas, a total of 68 homes sustained some form of damage. Of that, 17 single family dwellings and 13 mobile homes were destroyed. Eight single family dwellings sustained major damage and 11 others had minor damage. One mobile home sustained minor damage. Fourteen other single family dwellings and four other mobile homes were affected. In one of the destroyed mobile homes, an elderly man and woman were inside. The woman was killed immediately, and the man was seriously injured, dying one week later in a hospital of tornado-related complications. This becomes eastern Oklahoma's first killer tornado since the April 1994 Catoosa tornado. Across OK Hwy 51 in Sequoyah State Park, between 400 and 500 trees were lost to the tornado. The carport at the park manager's residence was destroyed, and an RV was turned on its side. Fortunately, most Memorial Day campers had cleared out, therefore there were no injuries in the park. F69MH, M69MH 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.

		Brief Description: EVENT NARRATIVE: This segment is the sixth of six segments of this long-track tornado. The tornado overturned a box truck on Highway 412, injuring its driver, severely damaged a couple permanent homes, severely damaged a mobile home, snapped or uprooted numerous trees, and snapped numerous power poles. The maximum estimated wind speed in this segment of the tornado based on this damage was 125 mph. EPISODE NARRATIVE: Unseasonably warm and moist air spread into northwestern Arkansas ahead of a cold front. Scattered thunderstorms developed in the late evening and early morning hours ahead of the cold front as a weak upper level disturbance passed through the region. Large hail and damaging wind gusts occurred with some of those storms. Another round of storms developed on the cold front over eastern Oklahoma as it pushed into the area. Weak to moderate instability combined with very strong low level wind shear created an environment that supported supercell thunderstorm structures. Several supercells developed resulting in large hail and damaging wind gusts in the hours just before and after sunrise on the 31st. One of these supercells produced a long-track, strong tornado that killed four people in and near the town of Cincinnati in Washington County. Debris was transported by the tornado into northern Benton County and was reported in Bella Vista and Pea Ridge. The Northwest Arkansas Regional Airport (XNA) was closed for three hours to remove the debris from the flight line. Another supercell produced a short-lived, weak tornado in Carroll County that moved into Missouri.

		Brief Description: EVENT NARRATIVE: This tornado developed at 1620 cst in northeastern Craig County and continued into Ottawa County. The tornado moved rapidly eastward toward the town of Picher where it destroyed about 200 homes, killed six people, and injured another 150 people at about 540 pm. Damage in and around Picher was rated EF-4 on the Enhanced Fujita Scale. The tornado began moving more southeasterly near Picher and struck the north side of Quapaw. While this tornado was beginning to weaken east of Quapaw, the supercell produced another tornado a few miles east-northeast of Quapaw that merged with this tornado just east of I-44. After the merger of the two tornadoes, a single tornadic circulation reintensified and became about a mile wide for several miles before moving into Newton County MO. 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 4 miles west of Short, OK, and tracked 39 miles to a point about 7 miles southwest of Fayetteville, AR. Along the way, this tornado passed through portions of four counties but mainly affected sparsely-populated areas. It reached its peak strength as an F3 tornado in extreme southeast Adair County, OK, but mainly caused F2 damage in Washington County, AR. Fortunately, this tornado lifted before it reached heavily-populated Fayetteville. The tornado's first real property damage took place at a property between the Hogeye and Strickland communities, where the tornado peeled off the roof to a home, shattered windows, uprooted trees, destroyed two barns, and wiped a porch off of its stone foundation. Numerous trees were blown down along County Roads 212 and 214. Only a few miles away in the Cove Creek community, south of Prarie Grove, the tornado blew off a home's roof, demolished an enclosed garage, and destroyed a barn. A flagpole was bent almost in half, and a road sign ended up wrapped around a mailbox. The tornado uprooted a 200-year old walnut tree which then fell onto a pickup truck. About a half-dozen other oak and cedar trees on one property dating back at least 150 years were snapped or uprooted. The Washington County Judge's Office supplied a picture of a church near Cove Creek that was moved off of its foundation. Several poultry buildings along the tornado's path were also damaged. The property damage listed in this entry is for just that damage sustained in Washington County, while the F-rating reflects the tornado's peak strength in Adair County, OK. Summary of events for May 4 1999: Following a record tornado outbreak in Oklahoma on May 3-4, a significant severe weather outbreak affected northwest Arkansas on the morning and afternoon of May 4 as a vigorous upper level system continued to move slowly east. While there were many individual storms in the area on May 4, the most outstanding storm of the day was a supercell thunderstorm that spawned a tornado in Sequoyah County, OK, which then moved northeast for 39 miles to near Fayetteville. Other storms produced damaging winds and large hail.

		Brief Description: EVENT NARRATIVE: This tornado is an extension of the Ottawa County, Oklahoma tornado. A National Weather Service storm survey revealed that an EF-4 tornado crossed into Missouri just north of Iris Road, and tracked east southeast all the way across Newton County to just north of Fairview. Several people were killed in automobiles, including a firefighter who was storm spotting, as the tornado briefly reached EF4 intensity near the intersection of Highway 43 and Iris Road. One vehicle at this location was thrown 5/8s of a mile. The tornado then extended to a mile wide and EF3 intensity as it tracked across the intersection of Highway 86 and BB. Many of the 14 fatalities and 200 injuries occurred from just west of Highway 43 to Highway 86. The communities of Granby and Newtonia were also directly impacted from this tornado. EPISODE NARRATIVE: Three tornadoes were spawned from supercell thunderstorms that developed over southeast Kansas. These storms quickly moved into southwest Missouri causing devestating damage to homes, businesses, and trees in Newton, Barry, and Jasper counties. One tornado, with an intensity that ranged from EF-4 to EF-1, killed 15 people as it tracked through Newton and Barry counties, while another tornado killed one person in Jasper County.

		Brief Description: A significant long-track tornado first touched down in Sequoyah County 4 miles west of Short, moving northeast for 39 miles to a point about 7 miles southwest of Fayetteville, AR. This tornado clipped the extreme southeast portion of Adair County as the tornado reached its peak strength as an F3 tornado. Fortunately, the tornado travelled across an unpopulated portion of Adair County. However, an aerial survey by NWS personnel over extreme southeast Adair County revealed that every tree in a hardwood forest was completely leveled. 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.
