| Brief Description: EVENT NARRATIVE: This segment is the third of six segments of this long-track tornado. The tornado severely damaged a couple permanent homes, destroyed a mobile home, destroyed barns, snapped or uprooted numerous trees, and snapped power poles in this portion of Benton County. Two injuries occurred in the mobile home that was destroyed on Winwood Ranch Road. The maximum estimated wind speed based on this damage was 130 mph. The tornado continued into Washington 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 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: 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. | |||||||||||

| 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.

| 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: A tornado touched down just before 830 pm just south of Highway 76/86 between Exeter and Ridgley. Initial damage was limited to chicken houses and grain bins which suffered sporadic damage. The tornado quickly intensified as it crossed the Highway and moved north across a residence. Extensive damage occurred to the property including two storage buildings swept clean of their foundations, a dump truck flipped almost 30 feet, and the loss of the residence's roof. Nearly a dozen other vehicles suffered collateral damage, along with numerous trees stripped or uprooted. Three individuals were injured as their vehicle was flipped over. The tornado tracked for approximately four miles north of Exeter, causing significant damage to at least three additional residences. Numerous outbuildings were also destroyed along with hundreds of trees that were uprooted. The tornado reached a width of over one quarter of a mile at peak intensity, before dissipating just north of Highway CC. The damage assessment would place this tornado at the high end of an F2 rating on the fujita scale...with winds approaching 150 mph. | |||||||||||
