A violent two-day weather event in June 2026 triggered 66 tornadoes across 13 states.
In short: Over June 21–22, 2026, the United States faced a severe weather siege. A massive tornado outbreak and a 700-mile-long derecho combined to cause widespread destruction, power outages, and flooding. From Kansas to the Ohio Valley, the atmosphere turned volatile, leaving a trail of damage that reshaped local landscapes.
The event began on June 21, 2026, with an early morning EF2 tornado near Wichita, Kansas, which destroyed a mobile home and caused the first fatality. As the day progressed, the Storm Prediction Center monitored a complex setup involving a Mesoscale Convective System (MCS) and a Mesoscale Convective Vortex (MCV). These systems, fueled by moderate instability and strong deep-layer wind shear, moved across the Midwest. By the afternoon, supercells developed along an outflow boundary in Illinois and Indiana, producing numerous tornadoes, including a low-end EF3 that tracked over 15 miles near Dix, Illinois, killing two people.
On June 22, the focus shifted as a powerful derecho—a long-lived, widespread windstorm—traversed from Colorado through Oklahoma. This derecho stretched over 700 miles and produced wind gusts reaching 102 mph near Hinton, Oklahoma. The storm system caused significant infrastructure damage, including the derailment of a BNSF train between Woodward and Mooreland, where 160 shipping containers were blown off the tracks. In Oklahoma, Governor Kevin Stitt declared a state of emergency for several counties to facilitate recovery efforts after the storm downed nearly 100 power poles and left over 83,000 customers without electricity.
Beyond the wind damage, the system triggered significant flash flooding across the country. In Poinsett County, Arkansas, rainfall reached up to 8 inches in a few hours, while Lexington, Kentucky, saw residential flooding that required water rescues. The event even impacted international events, causing the first weather delay in World Cup history during a match in Philadelphia. By the time the systems dissipated, 66 tornadoes had been recorded across 13 states, resulting in three deaths and seven injuries, alongside millions of dollars in damages to homes, businesses, and public infrastructure.
