Tornadoes in the U.S. state of Illinois are common, with 3,214 tornadoes occurring within state boundaries since 1950. These tornadoes have collectively resulted in 235 deaths.[ improper synthesis? ]
Illinois' climate is relatively average, and is only ideal for the formation of tornadoes in certain parts of the year, especially February, March and May. Warm air from the Southern United States can reach up into the Southern Illinois, resulting in tornadic storms. Illinois' proximity to Lake Michigan also results in cold air moving toward the Ohio Valley, creating the "hot-cold" effect seen in the traditional Tornado Alley. Illinois has had large tornado outbreaks in the past, the most notable being the tornado outbreak sequence of December 18–20, 1957.
Illinois is vulnerable to tornadoes with an average of 35 occurring annually, which puts much of the state at around 5 tornadoes per 10,000 square miles (30,000 km2) annually. [1] Peak tornado activity occurs between February and May, but storms can and have produced tornadoes in the winter.

A widespread, destructive, and deadly tornado outbreak sequence affected the Southeastern United States from April 28 to May 2, 1953, producing 24 tornadoes, including five violent F4 tornadoes. The deadliest event of the sequence was an F4 tornado family that ravaged Robins Air Force Base in Warner Robins, Georgia, on April 30, killing at least 18 people and injuring 300 or more others. On May 1, a pair of F4 tornadoes also struck Alabama, causing a combined nine deaths and 15 injuries. Additionally, another violent tornado struck rural Tennessee after midnight on May 2, killing four people and injuring eight. Additionally, two intense tornadoes impacted Greater San Antonio, Texas, on April 28, killing three people and injuring 20 altogether. In all, 36 people were killed, 361 others were injured, and total damages reached $26.713 million (1953 USD). There were additional casualties from non-tornadic events as well, including a washout which caused a train derailment that injured 10.
A large, weeklong tornado outbreak sequence of 73 tornadoes occurred on May 3–9, 1961, impacting areas from Utah to the East Coast of the United States. Overall, the outbreak sequence caused 23 fatalities, 126 injuries, and $42.205 million in damages.

All documented significant tornadoes were instead given unofficial ratings by tornado experts like Thomas P. Grazulis.
