- Overview of thunderhead structure. This boiling thunderhead to the east stands above shaded strips of middle cloud in bright evening light. The sharp light-dark lowered edge at the base is where the main updraft rises to the left before turning right and blowing downwind aloft. Perspective compresses the view, making it tricky to separate elements of the scene.
