caption_attribution_description: English: Map of confirmed tornadoes and tornado warnings issued by the National Weather Service from October 20 through October 23, 2019, over the southeastern United States and tornadoes confirmed and surveyed by the National Weather Service. Map produced in QGIS with border outlines from the United States Census Bureau. National Weather Service warning outlines available from the Iowa Environmental Mesonet and tornado data available from the National Weather Service.
context_page_description: The tornado outbreak of October 20–22, 2019 was a significant severe weather event across the South Central United States. 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.
