Here is another interesting weather forecast animation from the Australian Bureau of Meteorology (BOM) which may be helpful for understanding the cyclic nature of the weather in the southern hemisphere

The interactive chart predicts surface pressure and rainfall for the next 7 days. It also gives a sense of the long term movements across the lower latitudes through Australia, New Zealand, Chile, Argentina and South Africa.
Clear skies are more likely when the centre of a high pressure system (marked H) is present with wide-spaced isobar lines.
Seeing these patterns has helped me to be more patient with the weather through understanding the inevitable cycle of these slow-moving systems and knowing that the next clear night is on its way (currently somewhere over the Indian Ocean, as the case may be).
