This picture was taken on the first day of my US road trip. As I had to buy some food, I parked the car near a supermarket and took a few shots of the sky. The clouds were moving fast and looked like they were painted by hand. A few minutes later when I returned from the supermarket, there was heavy rain and thunder and the sky was turned into an even gray surface.
