The rain that battered areas of Queensland on Tuesday is edging its way into South Australia before it dives into the southeast.
The heavy falls are the result of a significant pool of cold air, which has now begun its journey towards the southeast after it stalled over the NT.
This cold pool is weakening as it moves, but has its track set for New South Wales and Victoria, with widespread rain preceding it.
The rain is still adding up over Queensland, with Birdsville seeing another 18mm to 9am yesterday.
This has been their highest two-day rainfall in November since records began 10 years ago.
This has also brought them 37mm more than their monthly average.
As the rain pushed into South Australia it brought 20mm to Hawker in the Mid North.
This came on top of the heavy rain they saw this past weekend, now making it the wettest month in nearly three years and 32 years for November.
It is the eastern parts of South Australia that will continue to see the heavy rain into early Thursday.
The rain also became heavy over western NSW and Victoria yesterday and will continue to spread east during Thursday.
Some areas could see their best rain since around March with up to 40mm expected.
