Episode Narrative A strong closed upper level low pressure system advanced east across Central Texas during the evening hours of April 24th, which helped to mix a warm front north into portions of Deep East Texas and Northcentral Louisiana. As a result, warm, moist, and unstable air began to build north along and south of the front, as steepening lapse rates aloft spread east along the axis of increasing large scale forcing ahead of the low. This resulted in an increase in scattered to numerous showers and thunderstorms near and south of the warm front from the late evening hours of the 24th through the early morning hours of the 25th across East Texas and North Louisiana. Coupled with the strong wind shear present across the expanding warm sector, several supercell thunderstorms developed, with one supercell spawning six separate tornadoes from San Augustine Texas northeast to Eastern Union Parish Louisiana, directly impacting the cities of San Augustine Texas and Ruston Louisiana along its 150+ mile track across the NWS Shreveport County Warning Area. In fact, this supercell spawned another tornado across Northwest Morehouse and Southern Ashley County Arkansas, to complete its nearly 180 mile track before dissipating. Additional showers and thunderstorms developed farther north of the warm front along the I-20 corridor of East Texas, with locally heavy rainfall of 3-6+ inches resulting in areas of flash flooding across Southwest and Central Smith County.
Event Narrative An EF-2 tornado with maximum estimated winds of 130 mph first touched down along County Road 1277 where it uprooted and snapped numerous trees as it paralleled the road. It then widened and moved across Cedar Road where extensive tree damage led to structural damage to 54 structures in a neighborhood. As it continued, it ripped the awning off of a gas station and snapped the electrical transmission tower of a sub-station near the intersection of Highway 96 and Highway 21. A laundromat and several additional structures saw extensive damage as the tornado moved across the northern side of Downtown San Augustine. After tearing through the northern part of the city, it continued to uproot and snap trees nearby along County Road 353 before lifting just prior to the Shelby County line.
Initial assessments found that around 150 homes and about 10 businesses were damaged from this tornado across San Augustine County.
