There is a visible difference between high clouds, which are shown in white, and medium and low clouds, which are yellow. The active zone of the unstable warm front with thunderstorms is easy to discern in combination with the flashes from strokes of lightning. At 09:00 UTC the first flashes are seen over Poland and they very quickly extend to the eastern parts of Germany.
