Those sunset pics are incredible, you guys do such a wonderful job out in the field!
Back at home I snapped a few pics of a storm, and I must say I've never seen structure as good since I started observing, although it pales in comparison to some of the stuff that others post.
Taken on the 9th Jan, looking towards the west of Wagga Wagga.
I've never seen a real wall cloud before, but this feature looks similar to ones that I have seen in pictures. Not sure if it's just some scud or actually anything significant.
