The parent supercell that produced the two EF4 tornadoes, and eleven tornadoes in total, later became known as the 'Quad-State supercell'.

However, storm surveys found that the majority of the storm's path was comprised of two distinct EF4 tornadoes, with three short-lived and weak tornadoes in between them in northwestern Obion County, Tennessee. Įarly estimates suggested that the tornado family-identified by some media outlets as a 'Quad-State tornado', due to the storm's long track and similarity to the 219-mile (352 km) Tri-State tornado of 1925-may have cut a path of up to 250 miles (400 km) across the affected areas, making it the longest-tracked tornado in history. After crossing the Mississippi River into northwestern West Tennessee, that tornado dissipated, and a high-end EF4 tornado formed and moved through Western Kentucky, where the towns of Cayce, Mayfield, Benton, Princeton, Dawson Springs, and Bremen suffered severe to catastrophic damage. It crossed the Missouri Bootheel, causing additional damage and fatalities near Braggadocio and Hayti. The first notable tornado of the event began in northeastern Arkansas, near Jonesboro, before causing major damage in and near towns such as Monette and Leachville, Arkansas at EF4 intensity. The first of these supercells produced tornadoes that spanned across four Mid-South states. The most extreme impact was from a two long-track supercell thunderstorms that produced families of strong tornadoes.

The event developed as a trough progressed eastward across the United States, interacting with an unseasonably moist and unstable environment across the Mississippi Valley.

Evaluation of the Hurricane Research Division Doppler radar analysis software using synthetic data. The relationship between spatial variations in the structure of convective bursts and tropical cyclone intensification using airborne Doppler radar. A wavenumber-1 asymmetry arises, showing that in the downshear (upshear) quadrants of the TC, updrafts are more (less) frequent and deeper (shallower)… Rainband updrafts become deeper and stronger with increasing radius. The selected updrafts are then collectively analyzed by their frequency, radius, azimuthal location (relative to the 200–850 hPa environmental wind shear), structural characteristics, and secondary circulation (radial/vertical) flow pattern.

An automated algorithm is developed to identify the strongest rainband updrafts across 12 hurricane-strength TCs.
