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.
