The last few days of the month produced a significant tornado outbreak sequence lasting about four days. The outbreak on March 29th primarily affected Arkansas and Mississippi, with an F3 tornado directly hitting [[Cabot, Arkansas]] including [[Cabot High School]] around the same time students were getting let out. Five people were killed from that tornado, none of which occurred at the high school. Another extremely long tracked F4 tornado occurred in central [[Mississippi]], which initially touched down about 15 miles southwest of [[Hazlehurst, Mississippi|Hazlehurst]], and ended north of [[Meridian, Mississippi|Meridian]]. The tornado tracked about 127 miles before it finally dissipated, and killed 3 people.

This page documents the tornadoes and tornado outbreaks of 1976, primarily in the United States. Most tornadoes form in the U.S., although some events may take place internationally. Tornado statistics for older years like this often appear significantly lower than modern years due to fewer reports or confirmed tornadoes.

A major outbreak shifted into mainly Illinois and Indiana. The strongest tornadoes occurred in Illinois, including an F4 tornado in Sadorus, but one F4 tornado came very close to Lafayette, Indiana. The Metro Detroit suburb of West Bloomfield Township, Michigan experienced an F4 tornado on March 20, it is to date the last tornado stronger than an F3 to strike the Metro Detroit area.[8] More activity continued onto March 21 when the system moved across Ohio, Michigan, and Pennsylvania.

Five people were killed from that tornado, none of which occurred at the high school. Another extremely long tracked F4 tornado occurred in central Mississippi, which initially touched down about 15 miles southwest of Hazlehurst, and ended north of Meridian. The tornado tracked about 127 miles before it finally dissipated, and killed 3 people.

On March 30, tornadoes started forming again, but mainly in Texas and Louisiana before entering into Mississippi yet again. Tornadoes also occurred in Michigan, including an F3 which killed a person in Logan Township, Ogemaw County, Michigan.

One of the largest and most violent tornadoes ever recorded in Iowa moved in between the cities of Ames and Boone during the afternoon. The tornado began southwest of the small town of Luther, Iowa a little before 3:30 pm and moved north northeast. The tornado strengthened and grew larger (at some points, more than a mile wide) as it approached US 30 just east of the intersection of IA 17. The tornado turned toward the north with the small hamlet of Jordan, Iowa in the path. A small satellite F3 tornado formed on the southwest side of the main tornado and moved around the back side and to the east of the tornado around 3:40 pm before merging back with the parent storm north of Jordan by 3:50 pm. The small hamlet of Jordan was raked by the half-mile wide F5 tornado, destroying nearly everything in its wake.

The parent tornado turned north-northwest before encountering outflow from a storm to its northwest, pushing it in an ESE direction. An anticyclonic tornado formed to the east of the parent tornado and it went to the north following the parent storm about two miles to its east. It too felt the downburst winds from the northwest and was pushed to the east as well. The parent tornado began to shrink and weaken as it approached the Boone and Story County line northwest of Ames, lifting about four miles west of Gilbert, Iowa at 4:15 pm, but the storm was not through yet.

The downburst winds that had pushed the tornado to the east were now rampaging the countryside in northern Story County around Gilbert northeastward to Story City, Iowa where more houses and farmsteads were damaged or destroyed by the strong straight line winds, although there were no deaths and only a few injuries. More than 60 homes, and over 300 farm buildings were hit and destroyed by the family of tornadoes and the downburst winds that followed.[1]

Theodore Fujita (creator of the Fujita Scale) said the damage was most likely the most severe and extreme he had ever examined and also one of the most rare, referring to the anticyclonic F3 tornado that accompanied and mimicked the F5 tornado from the parent storm.

At same time of the supercell that produced the Jordan tornado, another supercell formed, producing an F4 wedge tornado with a width of 800 yards (730 m) near Lemont, Illinois and causing two fatalities and 23 injuries. The outbreak as a whole killed two and injured 35.[12]
