A weak shortwave trough shifted east across East Texas and North Louisiana during the morning hours of April 28th, where large scale forcing contributed to the development of showers and thunderstorms over East Texas, Southwest Arkansas, and North Louisiana. Cold air aloft associated with this trough resulted in steep lapse rates such that isolated severe thunderstorms developed over portions of East Texas and Southwest Arkansas throughout the morning and afternoon, where instances of large hail were reported. These storms diminished during the late afternoon, but a deepening upper level trough sweeping southeast across Oklahoma and Arkansas reinforced a cold front southeast across the Southern Plains and Ozarks region, where a complex of showers and thunderstorms developed by mid and late afternoon over these areas and quickly progressed southeast into the Four State Region. Despite the showers and thunderstorms that affected the area earlier in the day, instability remained adequate especially over East Texas, Southeast Oklahoma, and adjacent sections of Southwest Arkansas. As large scale forcing increased ahead of the trough, thus tapping into this unstable air, a squall line progressed southeast through all of the region during the late evening through the early morning hours on April 29th, producing widespread reports of damaging winds and large hail. A couple of isolated tornadoes also touched down across McCurtain County Oklahoma, with one tornado remaining on the ground from Eastern McCurtain County into Northcentral Sevier County Arkansas. These storms exited Southwest Arkansas during the early morning hours of April 29th.

This is the continuation of the Eastern McCurtain County EF-2 tornado. This tornado snapped and uprooted numerous trees along Kellum Road in Northwest Sevier County, and continued to touch down intermittently several times as it tracked southeast. It touched down again along Bellah Mine Road as it crossed DeQueen Lake, with additional trees snapped and uprooted along Story Creek Road and DeQueen Lake Road. Minor metal roof damage to a garage of a home also occurred in this area. The damage swath broadened as the tornado approached Highway 71, when it crossed Crosstrails Road, damaging the roofs of two chicken houses while uprooting and snapping numerous trees. The tornado continued on to cross Highway 71 where numerous trees were snapped, a single-wide mobile home was rolled and destroyed, and the roof of a farm building was partially damaged. The tornado snapped approximately ten more trees before lifting just south of Highway 71/371 several miles east of DeQueen just east of the intersection of Farm to Market Road. Although the tornado will be rated an EF-2 with estimated maximum winds near 125 mph, found in Eastern McCurtain County Oklahoma, the tornadic damage in North-central Sevier County was estimated to be EF-1, with estimated maximum winds up to 105 mph. The total tornado path length from Eastern McCurtain County Oklahoma into North-central Sevier County Arkansas was near 20 miles.
