"Out of the blue" is evolved form of an old idiom "a bolt out of the blue" or "a bolt from the blue". A bolt out of the blue also means something unexpected, like the occurrence of a bolt of lightning on a clear blue sunny sky. Whenever a situation arrives suddenly, we call it as "out of the blue" just as a lightening struck a clear sky and disappears quickly. Hence, we use this phrase to describe a "sudden situation". However, with the passage of time "a bolt out of the blue" changed to a shorter form as "out of the blue".
