EF1 tornado in De Soto Parish, Louisiana

This is a continuation of the Northwest Sabine Parish tornado. This EF-1 tornado began to weaken as it entered Southeast Desoto Parish, with maximum estimated winds around 95 mph. It snapped and uprooted several trees near the Pelican community, where a tree fell on a vehicle on Highway 175 just south of the Highway 483 intersection, resulting in an injury to the female driver in the vehicle. The tornado continued its northeast movement to Highway 177 north of Parish Road 507 snapping and uprooting several more trees before finally lifting. In all, this long track tornado from Eastern Shelby County Texas through Northwest Sabine and Southeast Desoto Parishes in Northwest Louisiana remained on the ground for 32.1 miles before finally lifting.

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. Other isolated supercells developed near and south of the warm front which spawned tornadoes across Northern Caddo Parish and Central La Salle Parish in Northern Louisiana, with other severe thunderstorms producing damaging winds across portions of Northcentral Louisiana as well, before the storms exited the region around daybreak on the 25th.
