A Photo a Week Challenge: Unusual Clouds

I had not flown in almost eight years. Back in April, I made a trip to Houston where we had to fly around a huge weather system. The frothy stew of clouds in this capture were on the upper side of that system as our flight approached the airport. I got a series of captures of the sunrise and this storm on this early morning flight!
