Severe weather in the South and Midwest regions of the U.S. caused multiple tornadoes late Friday, December 11, into early Saturday, December 12, 2021. The tornadoes tore through Kentucky, Illinois, Indiana, Mississippi, Missouri, Ohio, Tennessee and Arkansas, killing at least 100 people. One of the hardest hit areas was Mayfield, Kentucky, where a candle factory was severely damaged. More than 100 tornado warnings were issued Friday before midnight, the most warnings ever for any day in December. One storm cell was tracked on radar for approximately four hours through parts of four states and for more than 250 miles; it could end up being the longest continuous tornado in history once verified.
