In all my years of landscape photography I had never seen a natural formation of clouds like this.. It has the look of some sort of explosion. We have had some strange weather here following the passage of Tropical Storm Beryl; lots of dark low lying clouds but nothing like this. The good news is, the sun won out and by sunset most of the cloud bank was gone but for a while it had the look of Armageddon . Have a great weekend and thanks for the look.
