The 1967 tornado season was very active with numerous large, destructive, and deadly outbreaks taking place. In fact, the only months not to have tornado-related fatalities were February and November, although both saw numerous injuries. The deadliest outbreak occurred in April while the biggest one occurred in September. The month of December was incredibly active as well, producing an unusually high 61 tornadoes with 60 of them stemming from three large outbreaks that occurred during the month. This remains one of the most-active December's on record.

The most significant tornado outbreak of 1967 struck the Midwestern United States, killing 58 people, all in Illinois, and injuring 1,118. The deadliest tornado of the outbreak was an F4 tornado that devastated the south side of Chicago and surrounding suburbs, killing 33 and injuring 500. ^[5] The worst damage from this tornado was in Oak Lawn and Hometown, where many buildings were leveled. ^[14] As the tornado struck during the Friday evening rush hour, many of the deaths were in cars that the tornado picked up and tossed at red traffic lights. Several children were killed when a skating rink was destroyed, while others died in the collapse of a super market and the destruction of trailers. ^{[5] [14]} The other major killer of the outbreak was an F4 tornado that devastated the south and southeastern portions of Belvidere, Illinois, killing 24 people and injuring 450.

Outside Belvidere, the tornado leveled farms, but without any loss of life. One school bus was torn in half south of Harvard, but all on board took refuge in a ditch. The other killer storm of the day was an F4 tornado or tornado family that killed one and injured 100 as it struck Elgin, Lake Zurich, and Barrington Hills, Illinois. Homes were leveled at the latter location. ^[5] A tornado family with a maximum rating of F4 traveled for 59 miles (95 km) across Linn, Macon and, Knox Counties in Missouri, but missed every town along its path, destroying homes and barns.
