 Brief Description: EVENT NARRATIVE: A tornado began in southeastern Arkansas County, northeast of Arkansas Post. Initially, the tornado was weak and its track was mostly over open farm land. The porch of an old mobile home, being used as a hunting camp, was torn off. The tornado soon moved into the White River National Wildlife Refuge and intensified greatly. The U.S. Fish and Wildlife Service estimated that 1750 acres of timber were destroyed within the refuge. Most of these old-growth trees were snapped off. Three families were camping at Jacks Bay in the refuge. No one was injured, but the campers were unable to exit the refuge because Jacks Bay Road, the only road out of that section of the refuge, was blocked by fallen trees. It took several hours for county, state, and federal crews to reopen the road. Altogether, they had to cut trees off 2537 feet of roadway. A few of the falling trees knocked down power lines. The tornado crossed the White River, into Phillips County, east-northeast of Weber. This tornado was destined to be one for the record books. The total path length in Arkansas and Phillips counties was by far the longest tornado track ever recorded in Arkansas during the month of July. Also, it was only the eighth tornado in Arkansas history to achieve a rating of F2/EF2 in the month of July. EPISODE NARRATIVE: During the morning of the 30th, a large cluster of thunderstorms known as a Mesoscale Convective System (MCS) moved into Arkansas from the southwest. The MCS weakened, leaving behind a Mesoscale Convective Vortex (MCV) or small area of circulation aloft. During the afternoon, this MCV helped to trigger new storms and a few tornadoes.

Most of the damage in the city was along and a few blocks to the north of 22nd Street (Arkansas Highway 130). The tornado then passed through the southern part of the Country Club Estates area and moved out across farmsteads, finally taking a turn toward the southeast and ending northeast of Almyra. Altogether, some 800 homes were damaged, along with 82 businesses, and approximately 750 vehicles. Two schools, a community college's training center, a nursing home, and a sports complex were also damaged. Six people had to be rescued after the building housing a dollar store collapsed, trapping the people inside. About 3800 customers lost electric service in the Stuttgart area, and about 2000 customers were without telephone service. Seventy-five animals were treated for minor injuries at Stuttgart's animal shelter. EPISODE NARRATIVE: A cold front moved through Arkansas on the 9th, but the front then stalled and moved back to the north as a warm front on the 10th. Severe storms developed north of the front during the afternoon, with tornadoes developing closer to the front during the early evening hours.
