Between April 28 – May 1, 2017, a series of severe weather events affected the Central United States, producing life-threatening flooding and a major tornado outbreak. It formed out of a disturbance in the Southwestern United States on April 28, and caused significant impacts, including a heavy snowstorm in the Rockies, and other types of severe weather. Up to 3 feet (36 in) of snow fell on the cold side of the system, and up to a foot of rain fell in and around the central parts of the nation.

The most significant and damaging events of the storm unfolded late on April 29, when two large, long-tracked, and powerful wedge tornadoes struck areas near Canton, Texas, the strongest being an EF4. Together, the two tornadoes caused four deaths and many injuries.
