A longwave trough shifted east out of the Rockies and into the Central and Southern Plains during the day on March 27th, with the southwest flow ahead of the trough ejecting a series of upper level disturbances northeast across Northeast Texas, Southwest Arkansas, and Northwest Louisiana during the afternoon and evening. Meanwhile, a broad warm and moist sector had spread north across all of the Ark-La-Tex into Eastern Oklahoma and much of Arkansas ahead of this trough, with temperatures warming into the upper 70s and lower 80s areawide. This resulted in moderate instability developing as large scale forcing increased during the late afternoon through the evening hours, resulting in scattered to numerous shower and thunderstorm development across much of these areas. Increasing wind shear late in the afternoon also promoted the development of scattered severe thunderstorms over East Texas, Southwest Arkansas, and Northwest Louisiana, with various reports of damaging winds and large hail received. However, one lone supercell developed over Eastern Anderson County Texas, which produced multiple tornadoes along its track from Cherokee County northeast into Northwest Nacogdoches, Southern Rusk, and Southern Panola Counties, before eventually moving into Northern Desoto and Southeast Caddo Parishes in Northwest Louisiana. These storms eventually organized along a broken line as it pushed into North Louisiana, ahead of a cold front that shifted southeast into the area during the early morning hours of the 28th.

This is a continuation of the Southern Rusk County tornado. This tornado continued northeast towards Lake Murvaul, where it maintained EF1 intensity while snapping and uprooting numerous trees as it paralleled FM 1971. Upon reaching the lake, the tornado reached several residences along the shoreline where it increased in intensity as it snapped and uprooted more trees and damaged the shingles of many homes. By this time, the tornado had strengthened to an EF2, with estimated maximum winds of 115 mph. One person was injured at their residence on the shore of Lake Murvaul, while video of the tornado was recorded by a storm chaser as it crossed the lake. After downing trees which damaged several structures on the east shore of the lake, it weakened and produced more sporadic damage before lifting north-northwest of Gary City. A review of video, TDEM ground survey data, and Sentinel satellite data indicate that the tornado lifted for approximately 5 miles before it touched down again in Southern Panola County.

An EF2 tornado with estimated maximum winds near 125 mph touched down again from the same supercell thunderstorm that produced the tornado near and over Lake Murvaul in Southwest Panola County, with this tornado downing and uprooting about 10 hardwood and softwood trees along Highway 59 several miles south of Carthage. The tornado intensified as it tracked parallel to FM 2517 and ripped the roof off of a single family home. The tornado's damage path widened considerably as it moved between FM 2517 and County Road 405. Security footage from a local meat processing center in the Antioch community indicates that a multiple-vortex tornado developed as the storm continued and produced a wide swath of snapped trees north and south of FM 2517.
Along County Road 405, the multiple-vortex tornado continued to completely destroy 3 metal outbuildings and shift another single family home off of its foundation. At this same location, the tornado tossed an antique vehicle 50 yards and wrapped sheet metal around approximately 10 trees. The tornado continued to snap large softwood trees along County Road 407, and as it crossed FM 699, it caused major roof damage to a brick home near the intersection of County Road 407 and County Road 408. A single-wide manufactured home utilizing a pan anchorage system was pulled free from the anchors and destroyed, with some of the debris blown a couple of hundred yards into a field to the east.
Hundreds of trees were downed in an area along County Road 448. As the tornado crossed FM 31, a large outbuilding was destroyed, but portions of the wooden frame were anchored by bolts to the foundation and remained in place. In this same area, a large pine tree was uprooted and fell onto a single-wide manufactured home, killing a 46 year old woman with her husband suffering a head injury. Another tree fell onto a vehicle nearby and injured two additional people. The tornado continued northeast snapping and uprooting additional trees and it travelled north of FM 2517. It crossed County Road 470, County Road 471, and finally lifted just east of County Road 332.
