This page documents all tornadoes confirmed by various weather forecast offices of the National Weather Service in the United States from May through June 2026. Tornado counts are considered preliminary until final publication in the database of the National Centers for Environmental Information. Based on the 1991–2020 average, about 265 tornadoes occur in the United States in May, and 212 tornadoes occur in June. Activity spreads northward and westward in May, with the maxima moving into the Midwest and the Great Plains as the springtime jet stream patterns tend to occur farther north. Tornado activity slowly begins to dwindle in the Southeast while the potential for activity also increases in the Northeast.
