With warmer-than-average temperatures, December 2018 brought slight snowfall and a historic late-season severe weather outbreak to Illinois.
On Dec. 1, the National Weather Service confirmed 29 tornadoes in Illinois, an event that is considered the largest December tornado outbreak in state history, according to Brian Kerschner, a spokesman for the state climatologist office at the U. of I.’s Illinois State Water Survey. The second-largest number of tornadoes in December was 21 in 1957.
