| 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 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. | |||||||||||

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 developed 4 miles west of Short, OK, moving northeast to about 7 miles southwest of Fayetteville, AR. This tornado reached its peak strength as an F3 tornado as it clipped extreme southeast Adair County, OK. This tornado then clipped extreme northwest Crawford County, passing through an unpopulated, forested area in the Ozark National Forest. An aerial survey by NWS personnel just west of the Oklahoma/Arkansas state line west of Natural Dam revealed that every tree in a hardwood forest was completely leveled. Property damage listed with this entry reflects tree damage sustained in Crawford 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. | |||||||||||
