Further to our discussion about rainfall in southern SA over the coming months initiated by Farm Weather
, we didn't get around to including moisture from the Indian Ocean. Here's some BOM info I found released a couple of days ago.

"Wetter autumn favoured for much of northern and eastern Australia
"National Seasonal Rainfall Outlook: probabilities for Autumn 2012, issued 22nd February 2012
Wetter autumn favoured for much of northern and eastern Australia
The national outlook for March to May 2012 shows the following:
large parts of northern and eastern Australia more likely to have a wetter season
southwest WA, southern Victoria and Tasmania more likely to have a drier season
At this time of year, the outlook model has low skill outside the tropics and southwest WA; we advise caution using this output.
This outlook is mostly due to warmer than normal waters over the Indian Ocean; cooler Pacific waters associated with La Niņa have had a lesser impact."
There's plenty more including colored maps and probabilities, which I have not had the time to come to grips with.

Adelaide has hit 38.9 C already. This has the makings of a 3 day mini heat wave for some of us.
