On March 28, 1920, a large outbreak of at least 37 tornadoes, 31 of which were significant, took place across the Midwestern and Southern United States. The tornadoes left at least 153 dead and at least 1,215 injured. Many communities and farmers alike were caught off-guard as the storms moved to the northeast at speeds that reached over 60 mph. Most of the fatalities occurred in Georgia (37), Ohio (28), and Indiana (21), while the other states had lesser totals. Little is known about many of the specific tornadoes that occurred, and the list below is only partial. Unusually, the outbreak featured a significant tornado—of F2 or greater status—over Lake Michigan; this was one of only three such occurrences in April or March in more than a century, the other two having taken place on April 3, 1956.

Severe thunderstorms began developing in Missouri during the early morning hours. The storms moved quickly to the northeast towards Chicago, Illinois. The first tornado injured five people 35 mi southeast of Springfield, Missouri, in Douglas County.

Background
For the residents of the Great Lakes region and Ohio Valley areas, the only source of weather information was the rather vague forecasts that were issued in the local newspaper the day before or by word of mouth. The use of the word "tornado" was strictly prohibited in public weather forecasting until the 1950s because of the fear and panic it might cause. This policy would come under-fire in the years to come especially after the Tri-State tornado in 1925 that stands today as the deadliest tornado in American history.

On the morning of March 28, a deep low-pressure center positioned itself near Sioux City, Iowa, with a reported pressure of 28.96 inHg. Ahead of the low, temperatures over a broad expanse ranged from 20 to 25 F above average, indicating a robust warm sector. Around noon CST (18:00 UTC), temperatures ranged from 60 F in Chicago, Illinois, to 77 F in Montgomery, Alabama, with brisk low-level winds ranging from the southeast to south-southeast. These winds allowed a warm, moist air mass to advect northward from the Gulf of Mexico to the Great Lakes. A strong elevated mixed layer (EML) was present over portions of the warm sector. Meanwhile, a pronounced, eastward-shifting convergence zone, characterised by shifting low-level winds, helped promote the development of vigorous thunderstorms. Observations from Springfield, Illinois, and other weather stations, taken in the wake of the convergence zone, indicated anomalously low relative humidity, suggestive of a strong dry line.

Confirmed tornadoes
Prior to 1990, there is a likely undercount of tornadoes, particularly E/F0–1, with reports of weaker tornadoes becoming more common as population increased. A sharp increase in the annual average E/F0–1 count by approximately 200 tornadoes was noted upon the implementation of NEXRAD Doppler weather radar in 1990–1991. 1974 marked the first year where significant tornado (E/F2+) counts became homogenous with contemporary values, attributed to the consistent implementation of Fujita scale assessments. Numerous discrepancies on the details of tornadoes in this outbreak exist between sources. The total count of tornadoes and ratings differs from various agencies accordingly. The list below documents information from the most contemporary official sources alongside assessments from tornado historian Thomas P. Grazulis.

La Fox–Elgin, Illinois
Just before the noon hour, severe thunderstorms began forming 50 mi west of downtown Chicago. The first storm started to spawn killer tornadoes in DeKalb and then Kane counties, starting at 1:05 p.m. CDT. Upon touching down, the tornadoes then moved northeast at about 50 mi/h. The tornado in Kane County apparently first formed about 1 + 1/2 mi southeast of La Fox and moved northeast, later passing directly through downtown Elgin. Initially, the tornado destroyed numerous barns and a farmhouse, killing four cows. As it neared the southern outskirts of Elgin, it then wrecked another home, tossing about a baby and killing its father.

Observers occasionally reported a well-defined funnel cloud along the 300 to 880 yd path as the tornado continued into the business district of Elgin, destroying or damaging many structures. It destroyed six businesses, damaged many others, and also "partially wrecked" three churches. An opera house was wrecked as well, and the roofs of two churches sagged. A married couple died as the rear of a theater collapsed, four more—possibly three—as a brick church tower fell, and one additional as part of a façade caved in. Church services had been dismissed only two minutes earlier, saving the lives of parishioners and preventing more deaths in Elgin.

As the tornado left downtown Elgin, it destroyed numerous trees along with 25 homes and damaged 200 other residences. Shortly thereafter, the tornado probably dissipated, only to redevelop into a new tornado. Both isolated tornado and widespread downburst damage was reported as far as Wauconda, killing more than 38 cattle, damaging farmsteads, and destroying many buildings, including at least two more barns. According to the Monthly Weather Review, the tornado may have traveled 30 mi before dissipating. It was the first tornado of the outbreak to cause deaths and to kill more than five people.

Bellwood–Maywood–Melrose Park–Dunning, Illinois
Roughly 15 minutes after the Elgin tornado formed, a violent F4 tornado family tore through Will and Cook counties, producing a 53 mi path through the Bellwood–Maywood area. The tornado first destroyed a 90 ft chimney, 12 or more barns, two frame schools, and five homes as it passed from Channahon to Troy and thence to Lockport. Many large oak trees were prostrated as well, and 17 people were injured, some severely, while losses totaled $500,000. The tornado skipped thereafter, possibly dissipating and redeveloping into a second tornado, as it caused minor damage in the Romeoville area. Afterward, the tornado was not seen for some time.

Upon reaching the Bellwood–Maywood area, the parent storm probably generated a second tornado, which produced a continuous swath of damage that extended to Lake Michigan, killing 20 people and leveling many homes. At first the tornado wrecked 20 homes in the Bellwood–Maywood area, claiming four lives and injuring three other people. The tornado was deadliest at Melrose Park, where 10 of the deaths alone occurred At Melrose Park the Sacred Heart Catholic Church and Convent was leveled, and a 1 t bell from the church was found 100 ft distant. Besides the church, a brick school and approximately 50 homes were destroyed or severely damaged.

The tornado then continued over less-populated areas, killing six more people in the community of Dunning. 18 people were injured, dozens of trees uprooted, and a few churches damaged at Wilmette before the tornado passed over Lake Michigan. In all, the tornado partially or completely destroyed 413 homes and injured about 300 people.

Susanna–Red Ridge–Agricola–Camp Hill, Alabama/West Point, Georgia
This violent, long-tracked tornado first developed southeast of Eclectic between 4:00–4:45 p.m. CDT, but most likely around 3:45 p.m. CDT according to Thomas P. Grazulis. Near Eclectic the tornado unroofed outhouses, felled trees, and partly damaged a building at a school. After striking Red Hill, the tornado caused 17 or more deaths while destroying 60 homes of both small and large stature in Alabama, mainly near Susanna, Red Ridge, and Agricola. Additionally, many rural outbuildings were obliterated. A short distance east of Camp Hill the tornado unroofed several barns and wrecked tenant houses. As many as 15 of the deaths occurred in or near Camp Hill, and 50 people were left destitute there; a number of severe injuries were documented. Beyond this settlement damage was less severe and no additional deaths were reported in Alabama. Afterward, the tornado crossed into Georgia, causing nine deaths and 40 injuries in West Point, where four square blocks incurred damage. In all, 40 homes were destroyed in Georgia.

Ossian–Townley, Indiana/Brunersburg–Swanton–Raab Corners, Ohio
The tornadoes that struck the western counties of Darke, Defiance, Mercer, Paulding, and Van Wert in Ohio on March 28, 1920, originated in the Hoosier State, quickly moving across the state line into Ohio.

The first of the tornadoes began in Indiana around 6:15 p.m. EDT. Probably part of a tornado family, it touched down near the Wells County community of Ossian. Increasing rapidly in size and intensity, the tornado was reported by eyewitnesses to have resembled a very large, low-hanging mass of turbulent clouds that resembled boiling pot of oatmeal. This may have accounted for the deaths and injuries of so many farmers within its path, since many farmers were usually accustomed to taking shelter during dangerous weather situations. The tornado caused nine deaths on farms outside Ossian, leveling entire farmsteads. The tornado then destroyed nearly every building at Townley. Four people died there as the entire town was devastated. The powerful tornado subsequently hit Edgerton before entering Ohio. In Indiana the tornado destroyed numerous farms, leveled at least 100 buildings, killed 13 people, and left behind $1,000,000 in damage (1920 USD) in the state. It later became the first of three tornadoes to move into Ohio, this time from Allen County, Indiana.

After moving through Paulding County, the tornado alternately lifted and dipped to the ground, possibly even reforming as a separate tornado, as it moved into the Brunersburg area, near Defiance. Here several homes and a small store were destroyed and six people lost their lives. The violent tornado then moved northeast into Henry and Fulton counties, tearing through the town of Swanton, and causing major damage. Many factories, shops, and homes were completely demolished. According to the Toledo Blade newspaper, the central business district sustained very heavy damage along Main Street, extending into nearby residential areas, where the damage became more intense. This damage brought out many thieves who looted local businesses and houses that had been hit by the tornado. Continuing on, the tornado then caused isolated damage to farms and trees as it passed into rural areas.

Increasing in size as it moved into northwest Lucas County, the tornado produced increasingly severe damage, as buildings and homes were swept clean of their foundations, before leveling the entire community of Raab Corners, also called Raabs, Rab's Corners, or Rabb's Corner, in Lucas County. Farmhouses and other buildings were leveled as the violent, 1/2 mi tornado moved towards Raab Corners. The residents of Raab Corners were largely unaware of the impending danger as they celebrated Palm Sunday services at the Immaculate Conception and St. Mary's Churches that evening. Just after 8:00 p.m. EDT rain and small hail started to come down in torrents. As the power went out churchgoers lighted kerosene lamps to illuminate the interior of their buildings, and to continue their Palm Sunday services, when the winds began to increase followed by large hail that shattered all the windows. Around 8:15 p.m. EDT, a solid black wall of swirling clouds proceeded to engulf Raab Corners, destroying everything in its path and killing four people. Local residents decided not to rebuild the town, moving to nearby communities in Michigan and Ohio. Today, only an intersection remains at once was the main four corners.

West Liberty–Geneva–Ceylon, Indiana/Van Wert, Ohio
This tornado developed in east-central Indiana and crossed into Mercer and Van Wert counties in Ohio. Upon touching down in Indiana, the tornado severely impacted West Liberty, Indiana (seven deaths), located north-northwest of Portland, before leveling homes between Geneva and Ceylon. In this area, the tornado partially stripped chickens of their feathers—a common phenomenon known as moulting—and swept many buildings away, some of whose floors it dislodged slightly. Thereafter, it leveled farms and killed three people in neighboring Ohio. In this area, the tornado was very intense and may have even reached F5 intensity, being one of the strongest tornadoes recorded this day. After exiting Adams County, Indiana, this large tornado moved towards the far northwestern part of Mercer County in west-central Ohio, again destroying nearly everything in its path. As the tornado moved on into Van Wert County, three more people died and many would be injured as the storm moved to the south of Van Wert. Some of this same area was hit by another F4 tornado on November 10, 2002.

Fenton, Michigan
The third and final F4 tornado in Michigan this day touched down west-northwest of Fenton at about 7:30 p.m. EDT, shortly before "8 o' clock," though one estimate suggested a time of 6:00 p.m. EDT. The tornado first destroyed a barn, a farmhouse, and a school as it moved northeast. It then struck a cement plant and demolished a smokestack and destroyed the steel-framed kiln room, reportedly warping and twisting the steel bars "so badly...that it is probable that the enclosure will have to be rebuilt." Total losses reached $100,000 at the plant. Afterward, the intensifying tornado leveled farm buildings and killed two horses and several other livestock; it left cows unharmed but pinned under debris. Crossing Long Lake, later renamed Lake Fenton, the F4 tornado then struck and completely leveled about 30 lakeside summer homes, many of them large and well-built structures worth $3,000–$6,000 to build at the time. Intense winds lifted boats up to 300 ft from their moorings and carried entire homes several hundred feet from their foundations. In the summer, according to the Fenton Independent, there would have been "hundreds of people camping at the lake. Should the accident have occurred at that time there would have been hundreds of deaths." In all, the powerful tornado killed four people and damaged or destroyed 35 buildings near Fenton. One of the deaths occurred in an overturned car, among the earliest tornado-related deaths in an automobile; the earliest known such death was probably on May 19, 1918, in Iowa.
