This extremely long-tracked F4 tornado began near Aden, littering I-64 with trees and overturning a truck before striking Barnhill, where 10 homes were destroyed and 10 others were damaged. The tornado then struck Albion, where a factory, homes, and other buildings were destroyed. The tornado then caused severe damage in the Browns area, where one woman was killed in her home. In the town of Mt. Carmel, the tornado ripped apart seventeen homes and severely damaged Wabash Valley College before crossing into Indiana. In Indiana, the tornado passed near Hazleton, Bowman, Petersburg, and Orrville, where a barn was destroyed. In Daviess County, Indiana, the tornado caused $10,000,000 in damage as it destroyed 10 homes and damaged 35 others.

A total of eleven people were injured by this tornado.[4]

A powerful F4 tornado developed west of Union and proceeded to enter that community from Gibson County. The tornado completely leveled one home, killing two occupants, and also blew another 30 feet (9.1 m) off its base. After passing through a wooded area, the tornado hit Petersburg, killing four people there. Upon entering the town limits, it leveled a nursing home plus an apartment complex and up to ten homes. Having now killed six people, the tornado was the deadliest to hit Indiana since the 1974 Super Outbreak.[3] It then struck the business district in downtown Petersburg and destroyed 19 businesses before going on to level 168 additional homes and damage an elementary school in Petersburg. The town became the hardest hit in Indiana on June 2, 1990.[2] The tornado destroyed half of Petersburg, including the home of the mayor. 60 others were injured by this tornado.[4][5]

A violent nighttime tornado began west of Bright, Indiana, with 50 homes destroyed in that area. Four of the homes were of brick construction, yet were completely leveled. The F4 tornado then continued to produce F4 damage in Ohio as it hit the communities of Harrison, Crosby Township, and New Baltimore. In Hamilton County alone, the tornado damaged 800–900 homes and 31 businesses plus three schools; of these, 32 homes were reported destroyed, some so completely that their foundations were left "practically barren".[3] Steel beams, 18 inches (1.5 ft) wide, 75 feet (23 m) long, and ⁵⁄₈ inch (0.052 ft) in thickness, were deformed and brought to ground level in Harrison. The tornado continued into the southern part of Fairfield and surrounding areas of Butler County, where 19 homes and four trailers were destroyed, with 58 homes, 22 trailers, and five apartment buildings damaged. The tornado continued into Warren County before dissipating near Mason. A total of 37 people were injured by this tornado.[3][4]
