The nation's south-east is set for a mammoth drenching, with a persistent southerly trough causing windy weather, showers, coastal thunderstorms and chilly conditions for millions of Aussies.
Sky News Meteorologist Alison Osborne has warned 'thundery showers are here to stay' with continued wet weather forecast for vast swathes of the south-east.
From Tuesday morning onwards a low-pressure system is set to intensify, bringing another burst of wet weather across southern parts of Victoria, with flash flooding also expected.
Ms Osborne stressed that the system would bring a 'high risk of some thunder in the mix with those showers' on Tuesday afternoon, especially for those residing in Canberra, Sydney and Newcastle.
'I don't have the sunniest news for millions of Australians along the east coast as there's more wet weather on the way' Ms Osborne said.
The low-pressure system will bring particularly strong showers to the NSW coast and northern ranges from Wednesday through to the end of the week.
'That wet weather will push further north from Wednesday night onwards up into northern NSW, with the coastal fringe likely to be under some pretty persistent wet weather between now and Friday'.
On Thursday, wet weather will generally be 'limited to the coastal fringe' Ms Osborne stated.
Residents based along the coastal fringe of NSW should expect 50 to 100mm of rain between now and next Monday.
By the middle of the week, it will be Victoria's turn to bear the cold front, with many areas set to stubbornly remain in the mid-teens.
Canberra and Sydney will also be feeling the chill factor from Wednesday afternoon, with Thursday predicted to be the harbour city's coldest day in three months.
The southerly winds will maintain cooler than average temperatures across Tasmania from Wednesday onwards, with the system causing some of the coldest weather since October for much of the south-east.
