The April 1956 tornado outbreak was a large, deadly tornado outbreak that affected the Great Plains, parts of the South, and the upper Midwest in the contiguous United States. Occurring from April 2–3, 1956, the outbreak produced 47 tornadoes, including an F5 tornado that devastated the Hudsonville and Standale, Michigan areas in the U.S. state of Michigan on April 3. It was one of three tornadoes to move across southwest Lower Michigan on that day. A fourth tornado struck north of the Manistee area. The Hudsonville-Standale tornado killed 18 and injured 340. In addition to confirmed tornadoes, there were several unconfirmed but possible tornadoes. An F2 may have hit east of Ogdensburg, Wisconsin, destroying a general store and a rural school. Nine barns were damaged or destroyed as well. A tornado may have also overturned two buildings and uprooted trees near Pana, Illinois. In addition to a confirmed F2 tornado near Topeka, Indiana, two other unconfirmed tornadoes may have hit northwest of LaGrange and at Emma, destroying or damaging numerous buildings, including a home and a barn that were blown down, and throwing (but not injuring) two people from a horse and buggy.
Tuesday, April 3, 1956, was a warm and humid day across most of the Midwestern U.S., the Great Lakes and the Ohio Valley. Temperatures in the areas affected by the worst of the outbreak were well into the 70s°F, approaching 80 °F with high dew points. A low pressure system with a strong cold front located across the western Great Lakes was moving to the northeast. The front was already responsible for deadly tornadoes in Oklahoma and Kansas on April 2 in which seven people were killed by the storms. Early on the afternoon of April 3, thunderstorms were already starting to form across Wisconsin, Illinois and Iowa, with the first deadly tornado reported in Wisconsin. A powerful F4 tornado struck the town of Berlin, Wisconsin, in which seven people were killed and a large portion of Berlin destroyed. Prior to the arrival of the storms in the Midwest, schools had closed earlier than usual due to the threat of severe weather.
