- Cloud base underside with chaotic cloud detail
- W902936Z
- A dark rain-free base fills the sky overhead, southeast of heavy rain with a severe storm. The chaotic cloud base underside surface has a strange greenish bright spot surrounded by lower cloud tags and scud. Here, sinking RFD air evaporates part of the cloud at the back (left side) of the main updraft and mesocyclone. The ragged base around it is a lowering disrupted by the downdraft.
