A strong upper level trough of low pressure extending from the Intermountain West into the Four Corners Region energized the southwest flow aloft across the Southern Plains during much of the day on May 8th, with a strong low level jet sustaining a mesoscale convective complex (MCS) across much of Oklahoma into Northcentral Texas south into the Texas Hill Country. While these storms gradually weakened after daybreak as a cold pool from these storms propagated southeast into the region, additional upper level disturbances ahead of this trough interacted with ample moisture and instability near this cold pool to intensify these showers and thunderstorms, some of which became severe with damaging winds as they moved across portions of East Texas, Southwest Arkansas, and North Louisiana. Strong low level shear was also present within the moderately unstable air mass, with discrete supercell thunderstorms developing across extreme East Texas and North Louisiana. This resulted in eleven reports of tornadoes across Northern Louisiana before the storms gradually weakened during the evening. However, locally heavy rainfall from the stronger storms persisted across portions of North Louisiana during the evening through the overnight/early morning hours of the 9th.

An EF-1 tornado with maximum estimated winds near 110 mph touched down near the Charles H. Garrett Community Center in the extreme southern portions of the city of Jonesboro where it damaged a small portion of the roof. It then crossed Highway 167 and snapped/uprooted trees along the highway and damaged a metal building where the column anchorage failed. Several more trees were snapped and uprooted along the path as it crossed Firetower Road, Highway 147, Rome Road, and Holiday Lane. The tornado then lifted after crossing Highway 4.

An EF-1 tornado with maximum estimated winds near 100 mph briefly touched down just west of Highway 167, where it snapped and uprooted approximately 15 trees as it crossed Highway 167 and then quickly lifted.

An EF-1 tornado with maximum estimated winds near 110 mph that was embedded within a squall line touched down on Poda Road where several trees were snapped. The tornado continued east, crossing Dewberry Road and Northstar Lane where numerous trees were snapped and uprooted. The tornado then crossed Caney Lake Reservoir and into Jimmie Davis State Park, where it snapped and uprooted numerous hardwood and softwood trees. Some of the trees fell into multiple campers and approximately three-fourths of the cabins in the park. The tornado lifted as it exited the north end of the State Park.

An EF-1 tornado with maximum estimated winds near 110 mph touched down in the community of Clay near Homer Sisemore Road, where it snapped and uprooted numerous trees, ripped the roof off of a small outbuilding, completely destroyed a shed, and ripped shingles off of the roof of a single family home. The tornado continued northeast, crossing Bonnie Blue Lane and tracking along Highway 167, snapping additional trees before entering extreme Southeast Lincoln Parish.

This is a continuation of the Lincoln Parish EF-1 tornado. This tornado weakened slightly as it crossed Riser Road back into Jackson Parish, with maximum estimated winds around 105 mph as it continued northeast across extreme Northwest Jackson Parish. Numerous trees were snapped and uprooted as the tornado tracked northeast across and along Edmiston Road before lifting on Countyline Road near its intersection of Edmiston Road.

25 minutes of warning. NWS SHV issued a tornado warning for this county at 22:17 UTC, 25 minutes before the tornado touched down, in force until 23:00 UTC.

The county was under a tornado watch, issued at 21:03 UTC and running to 00:20 UTC.

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 Enhanced Risk, with a 0.10 chance of a tornado within 25 miles. The outlook in force was issued at 19:56 UTC.

17 more were confirmed in the United States that day.

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.
