The May 15–17, 2013 tornado outbreak was a small but intense and deadly tornado outbreak that produced several damaging tornadoes in northern Texas, south-central Oklahoma, northern Louisiana, and northern Alabama. In mid-May 2013, an upper-level shortwave trough tracked across the Southern Plains of the United States. An associated low-pressure area and atmospheric instability resulted in the formation of tornadoes across northern Texas and Oklahoma on May 15. Afterwards the storm system weakened as it tracked westward, though six additional tornadoes were reported in Texas, Louisiana, and Alabama in the two days following May 15. Over a period of nearly two days, the storm system produced 26 tornadoes in four states. The strongest of these was an EF4 tornado which struck Hood County, Texas on May 15. However, on May 16 and May 17 no tornadoes were confirmed to have been stronger than EF1 intensity. In addition to tornadoes, large hail was reported, peaking at 4 in (10 cm) in diameter near Mineral Wells, Texas on May 15.
The EF4 tornado in Hood County, Texas, accounted for all six deaths caused by the severe storms, making it the first deadly tornado event in Texas since the 2007 Piedras Negras-Eagle Pass tornadoes. An additional 63 people were injured, many of which were due to the same EF4 tornado. A second tornado, rated EF3, was similarly damaging and impacted areas southwest of Cleburne, Texas, injuring seven. Damage across the four states due to the storm system reached roughly $272 million in damage.
