Yi Jing

It's a bit of a cloudy day, warm but cloudy and I was bored having watched all the re-runs of Rocky & Bullwinkle so I got out my three I Ching coins and threw them six times, and recorded the number of heads and tails The question I wanted answered was "Am I going to have a successful career?"
adding up my score I got "expect rain."
I'm confused by this answer, can anyone suggest interpretations that would be easier for me understand?
