The April 2022 North American storm complex affected much of the Rocky Mountains and the Midwestern United States with tornadoes, heavy snow, and gusty winds. The system in general first began impacting the Northwest on April 11, before moving eastward into the Rocky Mountains the following day. It was also responsible for producing a large severe weather outbreak of tornadoes and damaging straight-line wind in the Midwest and South while contributing to a powerful blizzard in the upper Midwest states of North and South Dakota.

In the upper Midwest, the system brought record-breaking snowfall and blizzard conditions to North and South Dakota and adjunct states, producing up to 3–4 feet (36–48 in) of snowfall and knocking power out to thousands and killing at least one person. The warm side of the system also knocked power out to thousands in the South and produced 74 tornadoes, with the strongest being rated EF3, and very large hail as well. One non-tornadic death was attributed to the severe weather in the South, while another non-tornadic death occurred in North Dakota when a blizzard hit the area.
