A chilly winter blast will sweep across Australia this week as winds from the Antarctic, snow and several bands of rain wreak havoc.
A cold change is heading towards Australia from south-east from Tasmania, and will move into NSW in the coming days.
On the other side of the country, Perth will receive its heaviest rainfall this year as a slow-moving low pressure system brings totals potentially exceeding 85mm over Tuesday and Wednesday.
The extreme conditions in the first week of winter comes after Australia enjoyed its fourth warmest autumn on record.
The south-western regions of Western Australia will a cop a soaking after a relatively dry start to 2025 with below-average rainfall in its capital.
Bureau of Meteorology senior meteorologist Angus Hines told Daily Mail Australia thunderstorms presented the main threat to south-western WA.
‘(We’ve just) had the first band of what will probably be a few different bands of showers and storms between now and Wednesday,’ he said.
‘Parts of western WA will see a good few storms out over the water, which are headed towards Perth over the next few hours.
‘Then that’s going to become quite a common pattern between now and Wednesday.
Perth is forecast to cop its highest rainfall this year as several rain bands approach WA
Perth is set to receive its heaviest rainfall this year with more than 85mm expected in the coming days
‘They’ll likely see bands of showers embedded with a few storms, and then in between those bands, it’ll probably brighten up again and the sun will come out, and then another band will roll through.’
There is a chance that thunderstorms could develop into severe thunderstorms with damaging wind gusts or extra heavy rainfall which could produce flooding in coastal areas.
‘That risk is there for well the next few hours, as this first band goes through that it come back on Tuesday with another another spell of showers and storms,’ Mr Hines said.
West Australians will see the system start to weaken by Thursday.
‘There might be a few lighter showers lingering, but the venom will have been sucked out of this weather system,’ he said.
Some bands of rain may reach as far north as the Pilbara, bringing unseasonal showers to the area, but in a diminished capacity.
Elsewhere across Australia, a cold change is making its way towards the south-east mainland.
‘(That) has been slowly crossing Tasmania and on Tuesday morning, that’ll move across Victoria and about the southern half of South Australia,’ Mr Hines said.
‘Then on Tuesday night and into Wednesday, that’ll move up through through NSW.’
Light rainfall was expected across many regions of Australia, but is expected to ease in the ease over the week
A cold change is heading towards Australia south-east from Tasmania , which will move into NSW later this week
The cold front will likely bring rain and a little snow to the higher peaks of Tasmania.
‘As the slightly cooler air kicks in on Tuesday, we could certainly see some snow falling across both the Tasmanian mountains and then eventually, a little bit later on tomorrow, Victoria and southern NSW mountains,’ Mr Hines said.
The chance of rain will ease over the week, however, the frosty air is expected to stick around for several days, with plummeting overnight temperatures expected.
Meteorologists expect rainfall totals to be minor, in good news for the rain-battered regions of the NSW north coast, which are only now starting to recover from the damage of the recent flooding.
‘Sometimes fronts can bring really vigorous and punchy sort of rain and storms and big accumulations of snow,’ Mr Hines said.
‘But this one is only bringing pretty minor rainfall totals really. There will be a bit of rain with it today and tomorrow as it moves northwards, but certainly nothing significant and not likely to be heavy rain or flooding.’
‘So it’s just going to be the snow and the cold air will be more of the notable effects of this front.’
The cold ‘pool’ is expected to hang over south-east NSW and Victoria, which could mean at least two days of snow for the alpine regions over the June long weekend.
The cold systems will, however, drop snow atop the southeastern alpine regions in Tasmania, Victoria, the ACT and New South Wales
Western Australia’s south-west will a cop a soaking this week after a dry start to 2025
Snow can be expected at lower levels as the coldest air of the front arrives, about 900m on the mainland and 600m of elevation in Tasmania.
The bureau issued a warning to graziers in areas of the NSW Snowy Mountains on Tuesday, warning the chilly conditions could cause the loss of lambs.
Marine wind warnings are also in place for much of the NSW coastline.
A second cold front will approach south-eastern Australia closer to the weekend.
That system is expected to bring snow to the highest areas of the Australian Alps on Saturday, just in time for the long weekend.
Cold air systems are expected to dispense snow to Australia’s highest regions, including the Snowy Mountains (above)
Another, more significant mass of cold air will hit the same regions on Sunday into Monday.
