A significant tornado outbreak impacted the South Central United States between October 20–22, 2019. Forecasters first identified the threat on October 16 as a large upper-level trough was expected to combine with an unstable atmosphere across Texas, Oklahoma, and Arkansas particularly. On the evening of October 20, discrete supercell thunderstorms developed across the Dallas–Fort Worth metroplex, contributing to several tornadoes. One of those tornadoes caused EF3 damage in the Dallas suburbs, becoming the costliest tornado event in Texas history, at $1.55 billion. A later squall line contributed to additional tornadoes and a widespread swath of damaging winds as the system tracked eastward.
