The April 7, 2020 tornado outbreak, known locally as Tornado Tuesday, was the first significant tornado outbreak of the year 2020. Between 6:42 AM and 11:04 PM, 42 tornadoes touched down across central and eastern Illinois and central Indiana, resulting in 29 fatalities. The outbreak was produced by an oblong cell line which began to form in the late afternoon of April 6. By the morning of April 7, over a dozen supercells had developed, many of which stalled over eastern Illinois and western Indiana for several hours. The most significant tornado of the outbreak was a long-tracked, high-end EF4 which impacted the city of Anderson, Indiana, resulting in 21 fatalities. A large, multiple-vortex EF2 tornado was responsible for an additional 6 fatalities in the town of Palmer, Illinois.
