Last night a low pressure system, accompanied by a trough, passed over NSW.
I observed what looked like summer lightning, an occurrence that sees the sky lit by sheets of lightning without clouds...discharges atmospheric as charges balance out.
Then the clouds rolled in.
They were slow moving and, initially, undetectable in a starry sky.
The following shot with stars visible...

Then the show got started.
The next shot of cloud that rolled in.

It was multi layered, with many cloud forms present at many levels.
The real dark ones on the RHS foreground were very low and very dense.
Quite ominous in their slow roll across the land.
The next day was sunny to start with, though a smaller second trough passed over around 8am giving some rain and this nice double rainbow.
