EF1 tornado in Bossier Parish, Louisiana

A weak EF-1 tornado with estimated maximum winds near 88 mph was spawned during the evening hours of June 23, 2026, from a quasi-linear convective line segment passing through and near the community of Plain Dealing. A vast majority of the damage was to trees with many hardwood and softwood trees being uprooted along the path. Sporadic softwood tree snaps throughout the assessed path of nearly 5 miles long garnered the peak wind speed of 88 mph for the tornado. Many power lines were downed in the path of the tornado, but the survey team determined that most of this occurrence was due to trees and tree limbs falling on the lines. It is also important to note that there were other sporadic instances of tree damage throughout northern Bossier Parish was due to the severe line of thunderstorms moving through during the evening, but the assessed tornado damage featured much more concentrated damage along a path.

A stationary front extended along the Red River Valley of Northeast Texas, Southeast Oklahoma, and into extreme Southwest Arkansas and North Louisiana during the morning hours of June 23rd, which focused areas of repeated showers and thunderstorms as an upper level disturbance shifted east-southeast atop the front. A very warm and moist air mass resided near and south of the front, which contributed to increased storm intensity and rain rates with areas of heavy rainfall falling over extreme Northeast Texas and North Louisiana during the morning. Widespread rainfall amounts of 2-10+ inches fell over portions of North Louisiana during the morning, contributing to areas of flash flooding. Isolated severe thunderstorms also developed over these areas during the evening through the morning hours on the 24th, with renewed flash flooding with additional rainfall amounts of 2-4+ inches falling. These storms also spawned an isolated tornado near Plain Dealing during the evening of the 23rd.
