Late during the evening of June 15th, regional radar analysis showed several clusters of severe thunderstorms ongoing along the middle Red River Valley into Northeast Texas. The eastern-most cluster displayed signs of cold pool intensification and developed a bowing structure. Observational trends farther downstream favored a continued motion along the instability gradient to the southeast through midnight into the early morning hours on June 16th. Given that the background wind fields and buoyancy were still quite strong, the threat of damaging winds upwards of 75+ mph and large hail increased as the complex moved into far Northeast Texas and Northwest Louisiana just after midnight.
Farther west near the Red River, additional storm development occurred along the trailing outflow. Less organized than the eastern cluster, individual storms, including a few supercells, eventually evolved and remained semi-discrete for a few hours. Given the more cellular nature, large hail was a threat initially with the amount of instability upwards of 5000 J/kg and 60 knots of effective shear. A greater risk of damaging winds gradually evolved as storms remained organized and grew upscale overnight.
As a result, large hail up to 2+ inches in diameter eventually occurred in some storms followed by an intense bow echo, resulting in widespread severe winds and even some hurricane-force gusts, setting the stage for initiating a derecho-type event across much of Northeast Texas and North Louisiana. In addition, an isolated tornado also occurred near the Texas/Louisiana state line on the south flank of the extreme derecho winds.

Property damage: 50.00K
Crop damage: 0.00K
Reported by: NWS Storm Survey

A strong line of thunderstorms moved through East Texas and Northwest Louisiana during the early morning hours on June 16th. As it moved through East Texas and into the Shreveport metro area, the storm begin to take on a bow shape, indicating that the system would likely produce strong straight line winds. As the storm reached near the Texas/Louisiana state line from Panola County into southwest Caddo Parish, it produced a brief EF-1 tornado with maximum wind gusts of 110 mph, a path width of nearly 850 yards, and path length of nearly two miles in far eastern Panola County.
With a storm already producing widespread straight-line wind damage, it became difficult to determine what was tornadic and what was straight-line winds. It was determined that the tornado touched down to the west of County Road 322 in Panola County where a large tree fell onto a single family home. The tornado then moved to the southeast across the Texas/Louisiana state line into extreme Southwest Caddo Parish.
