I always wanted to watch how weather changes in GWX but always had little of patience, since I'm always in TC till some action comes

Today I was sailing through Kiel canal in bad weather but I was lucky to stop TC just after the rain stopped and sky started to look brighter. I though wow never seen such sky like that before..

But after some couple of minutes, the sky cleared like an eye blink. Clouds just vanished without any fade out or smthng..
