I really like those ideas.
So, my Compel based on drawing power from the storm might be something like: "Since drew down power from the thunderstorm last week to cast your binding spell against a powerful demon, the rage of the storm has left it's mark on you. Normally, what Jake said wouldn't have phased you in the slightest, but today, you lose your temper and lash out at him for his foolish attitude toward something so serious."
Yeah, I really like that.
Or maybe the next time there is a thunderstorm, the connection you had established works in reverse and the storm somehow draws power from you. A Compel that takes efficacy away from a spell or two during the session.
