Cloud giant's castle

The clouds reflected the sunset this evening, painting the neighborhood in a golden light.  Seems like good real estate for a group of cloud giants.  Which brings up this question: Do you incorporate weather phenomena into your games--not just how rain might affect missile fire in combat, but things like thunderstorms, lightning, etc., or even just signs and portents like rainbows or halos around the moon or sun?

P.S. Don't forget, if you attend the South Texas Mini-Con, you have a chance to view great sunsets like this!  Mark your calendars for August 18.
