Over the next 7 days, the bulk of rain will be focussed on southern Australia as two weather systems move through.
By next Thursday night, broad areas across the south are likely to see between 25-50 mm, with higher totals along parts of the south coast.
The first weather system is a band of rain associated with a cold front and surface trough. On Friday, widespread rain is forecast in north-west and south-east Western Australia. Rain extends into South Australia from Friday afternoon, before sweeping over Victoria, Tasmania and southern New South Wales this weekend.
Moderate rainfall totals are possible, particularly over the Eyre and Yorke peninsulas, western Tasmania and north-east Victoria.
Temperatures will drop behind the cold front, however as this system has a link to humid tropical air, widespread cold temperatures are not expected. For example, on Sunday, Adelaide is forecast to drop to 17°C and Melbourne to 15°C, both of which are above average temperatures for June.
The second weather system is a cut-off low pressure system and trough that will develop over the Bight from next Monday. Scattered showers and thunderstorms are forecast across southern Western Australia, South Australia, Victoria and Tasmania during the first half of the week. These will extend to the east coast in the second half of the week.
Exact rainfall totals will depend on how this cut-off low moves; there is still some variation between the computer models.
