The 1983 season saw a relatively average number of tornadoes, but just four "violent" tornadoes (all F4, no F5's) and the number killed by tornadoes was lower than average at just 34, and no tornado killed more than three people. Two notable outbreaks took place in May, but it was generally a much less destructive tornado season, particularly in the main tornado alley, which saw no tornadoes stronger than F3.
