Here are some photos and a timelapse of a developing MCS. There are some shots missing in the video, since I had other things to do, so I haven´t noticed that the camera is full.
First some pictures, and then the video. :)
A brief supercell.
And a developing MCS.
And now the timelapse. The lightning was pretty good, but you can´t see that in the video, because of its speed. :)
