The former talk show host who began his career as a weatherman is David Letterman. After graduating from college in 1969, Letterman worked as a weatherman for a local ABC affiliate in Indianapolis. During this time, he was known for his quirky and unconventional on-air antics, such as congratulating a tropical storm for being upgraded to a hurricane and predicting hailstones "the size of canned hams." This early experience allowed him to develop the unique comedic style that later defined his successful career in late-night television.
