1967 St. Louis tornado outbreak


An extremely rare winter outbreak of 30 tornadoes broke out across the Midwest on January 24, 1967 with 13 of them in Iowa, nine in Missouri, seven in Illinois, and one in Wisconsin. The lone F3 tornado in Wisconsin was also the northern-most January tornado ever recorded in the United States at the time. This would later happen again on January 7, 2008, when several tornadoes hit Southeastern Wisconsin. This outbreak is also possibly the farthest north a tornado outbreak has occurred in the winter.
The tornadoes broke ahead of a deep storm system with several temperature records were broken in the Midwest on this day. One of the most notable tornadoes struck St. Louis County, Missouri at F4 intensity, killing three and injuring 216.
