December 11
 * 1949 – A tornado outbreak impacted states along the Mississippi River. An F4 tornado killed 6 people and injured 30 in rural areas west of Poplar Bluff, Missouri. An F3 tornado struck Providence, Arkansas and passed north of Bradford, killing 4 people and injuring 11, with 3 deaths in a house that was carried 50 yards (about 50 m).
 * 1990 – A tornado, estimated at F4 intensity by Ted Fujita, struck Mobara, Chiba Prefecture, Japan, damaging 1,000 homes, of which 82 were destroyed, and injuring 60 people. One house was lifted off its foundation before disintegrating, and steel rods at a construction site were bent to the ground. Video analysis indicated wind speeds of 93 m/s 120 m above the ground. Fujita's rating would make this the only F4 tornado in record in Japan.
