Weather event in the United States

A deadly tornado outbreak devastated parts of Louisiana and Tennessee on February 11–13, 1950. The outbreak covered about a day and a half and produced numerous tornadoes, mostly from East Texas to the lower Mississippi Valley, with activity concentrated in Texas and Louisiana. Most of the deaths occurred in Louisiana and Tennessee, where tornadoes killed 25 and 9 people, respectively. Several long-lived tornado families struck the Red River region of northwestern Louisiana, especially the Shreveport–Bossier City area. One of the tornadoes attained violent intensity, F4, on the Fujita scale and caused eight deaths, including six at the Shreveport Holding and Reconsignment Depot near Barksdale Air Force Base. It remains one of the top ten deadliest tornadoes on record in the state of Louisiana, in tenth place. Also in Louisiana, two other destructive tornadoes on parallel paths killed 16. Seven additional deaths occurred across the border in East Texas. Nine people died in a tornado in western Tennessee as well. In all, the entire outbreak killed at least 41 people and left 228 injured. Also, several long-tracked tornadoes recorded in the outbreak likely contained more, shorter-lived tornadoes.
Confirmed tornadoes.
Prior to 1990, there is a likely undercount of tornadoes, particularly E/F0–1, with reports of weaker tornadoes becoming more common as population increased. A sharp increase in the annual average E/F0–1 count by approximately 200 tornadoes was noted upon the implementation of NEXRAD Doppler weather radar in 1990–1991. 1974 marked the first year where significant tornado (E/F2+) counts became homogenous with contemporary values, attributed to the consistent implementation of Fujita scale assessments. Numerous discrepancies on the details of tornadoes in this outbreak exist between sources. The total count of tornadoes and ratings differs from various agencies accordingly. The list below documents information from the most contemporary official sources alongside assessments from tornado historian Thomas P. Grazulis.
Non-tornadic effects.
A severe thunderstorm generated strong winds just east of Pushmataha, Choctaw County, Alabama, at 6:00 p.m. EST (00:00 UTC) on February 13. The winds felled trees and damaged a trio of homes, one of which was leveled. Almost 18 hours previous barns and a few homes were damaged by strong winds at Marietta, Cass County, Texas. A day earlier hail and wind caused negligible damage to property in and near Winnsboro, Louisiana, as well.
