In April 2020, various weather forecast offices of the National Weather Service confirmed 251 tornadoes in the United States, indicating significantly above-average activity for the month. Based on the 1991–2010 averaging period, 155 tornadoes occur across the country during April. While the first three months of a year commonly feature tornadic activity across the Southeastern United States in close proximity to the Gulf of Mexico, this risk area expands to include the U.S. Midwest and U.S. Southern Great Plains in April, maximized in the states of Texas and Oklahoma. This expansion comes as powerful winter-like systems overlap with an increasingly warm and humid airmass from the Gulf of Mexico.
