Here's an occasional fun thing to do:
I've been using ISS overflights during daytime to get a more up-to-date and detailed idea of local cloud conditions, particularly when an astro 'event' is on that night (eg. tonight's eclipse!).
The ISS HD experiment has multiple external cameras (forward, down & rearward views) which alternate on a timer (scroll down).

By checking 'all passes' for ISS on HA, you can determine suitable overflights.
This one happened (over SA) around 15:20 today.

The screen-grab below shows Eyre, Yorkes & Fleurieu peninsulas, and the Coorong coastline & Kangaroo Island are also visible.
As you can see, there ain't much cloud around!
SkippySky is useful - but this is for real (& real-time)! BoM is good, but much lower resolution satellite images.
So, tonight's eclipse is pretty much in the clear for SA folk!
