Mountains are the
     Lamborghini of weather --
  from gray and dismal to
    gloriously sunny 
       and back again
           in record time. 
 It may rain and the droplets
   burn off before noon,
     leaving no trace of 
        the gloom.
  One day may feel
    multiple ways before 
      the sun goes down.

The human mind isn't
   built for such whiplash
      emotional experience.
