Here is a splitting storm near Lubbock, viewed looking west. Note the distant updraft base (looks like a separate wall cloud, but isn't) of the right mover. The left mover had a brief and weak landspout on it. (Barely visible in this picture) |

Now we are northwest of the right (south) mover. Note the rain "foot" off to our east. |
View back towards the northeast of main updraft, which was dying a ghastly death. |
