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.

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.

An EF-1 tornado with maximum estimated winds around 105 mph touched down just west of Toledo Bend Reservoir in Eastern Shelby County Texas near Forest Service Road 126 and continued northeast crossing County Road 2789 and County Road 3184 just north of Forest Service Road 126A. The tornado continued east along Forest Service Road 126 before crossing Forest Service Road 132, and eventually over Toledo Bend Reservoir into Northwest Sabine Parish Louisiana. Numerous trees were snapped and uprooted along the tornado's path across the Sabine National Forest before crossing Toledo Bend Reservoir.

This is a continuation of the Shelby County EF-1 tornado that touched down just west of Toledo Bend Reservoir shortly before midnight on April 24th. This tornado moved across Toledo Bend Reservoir as a waterspout, and back onshore in Northwest Sabine Parish as a tornado, where it crossed Highway 191 just south of Highway 174 before turning more easterly crossing Golden Road, snapping and uprooting numerous trees along its path. The tornado tracked through the town of Converse where several trees were snapped and uprooted before crossing Highway 171 and Highway 174, and led to additional tree damage on Harrison Road, Cooper Lane, and Bolivar Road before moving into Southeast Desoto Parish. The maximum estimated winds from this tornado as it moved throughout Northwest Sabine Parish was 105 mph.||Approximately five homes reported major damage, while fifteen other homes suffered minor damage from the tornado. A church also suffered damage from this tornado as well.

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.

16 minutes of warning. NWS SHV issued a tornado warning for this county at 04:26 UTC, 16 minutes before the tornado touched down, in force until 05:00 UTC.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Marginal Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 00:53 UTC.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
