List of United States tornadoes from May to July 2020

This page documents confirmed tornadoes from May to July 2020 via various weather forecast offices of the National Weather Service. Based on the 1991–2010 averaging period, 276 tornadoes occur across the United States throughout May, 243 in June, and 143 in July. The climatological peak for tornadic activity in the country, May features a risk area that is concentrated throughout the U.S. Great Plains, especially in the states of Texas, Oklahoma, and Kansas. This is a shift from earlier months where the highest concentration of tornadoes is focused around the U.S. Gulf Coast. Historical data shows a substantial drop in the number of violent (EF4+) tornadoes in May versus April, likely due to the loss of the amplified winter jet stream, and perhaps as a result of tornadoes tracking over more sparsely populated areas. However, intense tornadoes are still possible in any month of the year. Tornado activity in June typically shifts more north and west across the Plains, especially Northern Colorado and the Texas Panhandle. Tornado activity in July normally affects the Northern Plains and the Great Lakes.

With only 126 verified tornadoes, May 2020 turned out to be one of the least active months on record. No moderate- or high-risk outlooks were issued by the Storm Prediction Center throughout the month, a first since archives of outlooks began in 2002. June was even less active, with only 91 confirmed tornadoes. In addition, no EF2+ tornado was confirmed during June, this first time this had occurred since records began 1950. However, July saw its first violent tornado since 2004. June and July also saw several tornadoes coming from tropical cyclones.
