In short: Between April 23 and 28, 2026, a massive multi-day weather event unleashed 119 tornadoes across the central United States. From violent EF4 storms in Oklahoma to destructive hail in Missouri, the sequence caused widespread structural devastation, power outages, and significant economic loss, marking a period of intense atmospheric instability.

The outbreak sequence began on April 23, 2026, driven by a strongly unstable air mass across northern Oklahoma. As a capping inversion weakened, explosive convective development occurred, spawning discrete supercells. One particularly violent, long-lived EF4 tornado struck near Enid, Garfield County, that evening. This storm, which prompted a tornado emergency, maintained a persistent mesocyclone and exhibited cyclic characteristics. It tracked 9.5 miles over 37 minutes, reaching a maximum width of 600 yards. Researchers later estimated its peak winds may have exceeded the EF5 threshold, with some models suggesting speeds between 200 and 220 mph.

The severe weather continued through late April, with moderate risks issued for Oklahoma, Texas, Missouri, and Illinois. On April 25, a high-end EF2 tornado in Runaway Bay, Texas, killed one person and caused approximately $5 million in damages. By April 28, the focus shifted to North Texas and Missouri. In Mineral Wells, Texas, an EF3 tornado destroyed 132 buildings, including World War II-era warehouses, causing $2.3 million in damage. Simultaneously, a prolific hailstorm in Missouri produced stones up to 4.75 inches in diameter, shattering windows and totaling vehicles across a 123-mile path, likely becoming the costliest hailstorm in the city's history.

In total, the six-day sequence resulted in 119 confirmed tornadoes and at least 21 injuries. While the tornadic activity caused one death, two additional fatalities were attributed to non-tornadic impacts, including a tree falling on a man in Michigan. The event strained regional infrastructure, leaving thousands without power and requiring extensive search and rescue operations. The complexity of the atmospheric setup—involving both stationary and moving extratropical cyclones—highlights the volatile nature of spring weather patterns in the central United States, where moisture, lapse rates, and wind shear frequently converge to create high-impact events.
