Partly Cloudy On a Planet You Don't Live On

My 11-year-old daughter and I were trying to understand a science article for Arizona's amazing Large Binocular Telescope.  The story was about Arizona scientists looking at a planet  a bazillion miles away:  Non-equilibrium Chemistry Patch Clouds Model.   What does that mean she asks.   Before I could answer (as if I could) she said:  "I get it!   Partly cloudy today on a planet you don't live on...with a chance of rain!"
