EF2 tornado in Moultrie County, Illinois

This tornado crossed from Shelby County into southern Moultrie County about 1 mile southwest of Gays at 9:54 PM CST. An agriculture services plant was significantly damaged west of Gays, with numerous buildings destroyed and 3 large tanker trucks flipped. The tornado continued northeastward and crossed into western Coles County just south of Western Avenue at 9:58 PM CST.

A deepening area of low pressure tracked from near Kansas City during the afternoon of December 10th to southern Lake Michigan by the pre-dawn hours of December 11th. An unseasonably warm and moist airmass surged northward ahead of the system, resulting in high temperatures reaching the lower to middle 60s across central Illinois. As the low and an associated vigorous short-wave trough interacted with the moderately unstable and highly sheared environment, several clusters of strong to severe thunderstorms developed during the late afternoon and evening of the 10th. Numerous rotating cells were observed, with a total of 6 tornadoes touching down across central Illinois. 5 of the tornadoes were rated EF-2, including one that injured a person just north of Herrick in Shelby County.
