EF1 tornado in Warren County, Mississippi

A tornado began near the airport along Warrenton Lane, where some large branches were snapped. The tornado quickly intensified as it moved southeast and snapped and uprooted trees. It was most intense near Burnt House Road, where there was widespread tree damage and a large tree fell on a house. Numerous hardwood trees had snapped trunks and were uprooted. The tornado continued to snap and uproot trees along Funches Road near Drayton Road. There was also significant tree damage along Fisher Ferry Road and Fonsylvania Road. The tornado continued to track southeast and snapped and uprooted trees along an unnamed Warren County Road just south of Halls Ferry before it dissipated in wooded area. Wind gusts were estimated at 110 mph at the strongest. A tornadic debris signature was observed on radar with this tornado.

During the afternoon and evening of June 15th, an upper-level disturbance triggered a cluster of thunderstorms along a stationary front boundary around the Texas and Oklahoma border. These storms intensified and grew upscale into an intense mesoscale convective system (MCS) as they moved east-southeast along an axis of increased moisture and strong instability that extended toward the Central Gulf Coast. As the MCS moved into western Mississippi with a bow and arrow structure, it exhibited an unusually intense rear-inflow jet with velocities as high as 80 to 100 mph descending to around 1,000 feet above the ground, as viewed by the KDGX NEXRAD site. A wide swath of significant severe wind gusts at the surface caused widespread wind damage including snapped and uprooted trees, downed tree limbs and power lines, and damage to homes and other structures. Surveys of the wind damage indicated that peak wind gusts of 90 to 100 mph likely occurred in the most intense portions of the line. Over 240,000 power outages resulted in portions of the area and many continued for several days following these and other storms that occurred during the middle of June. Two embedded EF-1 tornadoes occurred with the squall line. There was one fatality in Madison County due to the straight line winds, and several other injuries were due to fallen trees across the state. Later in the evening, additional severe thunderstorms produced hail up to the size of grapefruits and caused scattered wind damage.
