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.
The Tornado outbreak of November 1992, sometimes referred to as The Widespread Outbreak, was a devastating, three-day outbreak of tornadoes that struck the Eastern and Midwestern United States on November 21–23. This exceptionally long-lived and geographically large outbreak produced 95 tornadoes over a 41-hour period, making it one of the longest-lasting and largest outbreaks ever recorded in the US, and published studies of the outbreak have indicated the possibility of even more tornadoes. There were 26 fatalities, 641 injuries, and over $300 million in damage.
This page documents notable tornadoes and tornado outbreaks worldwide in 2001. Strong and destructive tornadoes form most frequently in the United States, Bangladesh, and Eastern India, but they can occur almost anywhere under the right conditions. Tornadoes also develop occasionally in southern Canada during the Northern Hemisphere's summer and somewhat regularly at other times of the year across Europe, Asia, and Australia. Tornadic events are often accompanied with other forms of severe weather, including strong thunderstorms, strong winds, and hail.

A widespread and deadly tornado outbreak affected the Great Plains, Mississippi Valley, and Southeast between March 12–15, 1953. At least 23 tornadoes were confirmed with the strongest one reaching F4 intensity and striking O'Brien, Texas on Friday the 13th. Overall, 21 people were killed, 72 others were injured, and damages were estimated at $6.835 million (1953 USD). There were additional casualties from non-tornadic events as well.

Two additional fatalities also occurred due to flooding and lightning.
