On February 19–20, 1884, a large tornado outbreak occurred over the Southeastern United States, known as the Enigma tornado outbreak due to the uncertain number of total tornadoes and fatalities. Nonetheless, an inspection of newspaper reports and governmental studies published in the aftermath reveals successive, long-tracked tornado families striking Alabama, Georgia, Illinois, Indiana, Kentucky, Mississippi, North Carolina, South Carolina, Tennessee and Virginia, with an estimation of at least 51—and possibly 60 or more—tornadoes striking that Tuesday into Wednesday.

The majority of reported tornado activity was seen across Alabama, Georgia, South Carolina and North Carolina, which were all struck severely by multiple waves of tornado families. In the Southeast, the outbreak began during the late morning in Mississippi, preceded by severe thunderstorms in Louisiana. Shortly thereafter, the outbreak widened and intensified, progressing from Alabama to Virginia between noon and midnight. The outbreak also produced the deadliest individual tornado in North Carolina history, an F4 which swept through the Rockingham area, killing 23.

The following events were also reported:

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.

This was the first of a number of destructive North Carolina storms. Detailed coverage in a Wadesboro-based newspaper provides an unusually (by 19th-century standards) precise survey of the movement and damage produced by three of those storms in the southern Piedmont of North Carolina. This storm first formed in southeastern Union County, from a supercell that had produced significant damage in South Carolina earlier. Most of the path of this storm was in rural areas, with injuries and major damage along Beaverdam Creek, south of Marshville in Union County, and along Brown Creek in Anson County, northeast of Polkton.

Significant damage also occurred in and around the towns of Polkton and Ansonville, where structures in both towns were widely damaged, with homes and farm buildings destroyed south of Ansonville. A total of four people were killed: a pair in a "'mansion'" that was destroyed, and another pair in one of 28 homes that were wrecked on a plantation. Eyewitnesses in Polkton noted that the storm "crossed the railroad about a mile east of Polkton last night prostrating everything in its course. Could see the storm from Polkton by lightning, looked like a cloud of dense smoke and sounded like thunder. Hail stones measuring 2+1⁄2 in (6.4 cm) long, 1+1⁄2 in (3.8 cm) wide and 1 in (2.5 cm) thick fell."

Homes were also destroyed near Mangum in Richmond County and near Pekin in Montgomery County.

This storm was preceded and followed by a wide area of downburst damage – with scattered areas of damage to farms and small structures reported across a wide area of southern Cabarrus County, eastern Mecklenburg County (northeast of Mint Hill) and the Goose Creek area of northwestern Union County.
