Queensland is set for another soaking on Saturday, with some parts of the state expecting some heavy downpours before the weather systems moves out to sea.
A large trough has lingered over Proserpine down to parts of northern New South Wales and is expected to remain over Queensland’s south-east until late at night.
Areas between the Sunshine Coast and Rockhampton could see some heavy rainfall.
Wet weather is expected as far inland as Roma and Toowoomba.
The trough is forecast to slowly shift away by Sunday morning.
Sky News meteorologist Marina Neuman said some high totals are expected.
“What we’re looking at and what we are expecting in terms of total rainfall (over seven days) the potential for about 50 millimetres,” she said.
“That’s going to be from Roma to Toowoomba, the Gold Coast, and then all the way up to Rockhampton. We’re also seeing Port Macquarie with the chance for even 30mms there. So some decent totals are expected from this system before it finally clears out.”
Meanwhile a cold front is set to cross over the southern half of Western Australia on Saturday, bringing showers throughout the day from Albany up to Carnarvon.
It is expected to clear by Sunday, however, a second system is on the way.
Neuman said dry conditions are forecast but heavy rainfall is set to begin by Monday.
“We’re looking at widespread rainfall, dramatic drop in temperature, some strong winds as this very large low pressure system and associated trough push in,” she said.
“And this is expected to be a several-day system, so not only for Monday, but taking us into Tuesday morning and potentially even lasting into Wednesday.”
Perth, Bunbury, Busselton and surrounding areas can expect heavy falls.
Most parts of WA are expecting 50mm of total rainfall in seven days, while up to 100mms is forecast along the coast from Busselton to south of Geraldton.
It is also set to be a cold Saturday morning for millions of residents in parts of New South Wales, the Australian Capital Territory, Victoria, Tasmania and South Australia.
Wangaratta in Victoria is set to be -1C, while Orange and Wagga Wagga in NSW is forecast to be 1C and 2C, respectively. Canberrans are set to shiver through 1C.
A frost warning is also in place for parts of the four states and territory.
While it will be even colder on Sunday, the first official day of winter, with Australia’s capital and Orange at 0C, while Wagga will be 1C and Wangaratta -2C.
Neuman also warned of an extreme winter for parts of the country, pointing in particular to the north-eastern half of Victoria and portions of NSW such as the alpine.
“Looking at an 80 per cent chance for an extreme winter that means temperatures below average so very likely that we see those very temperatures continue as we head into the official start of winter,”the Sky News meteorologist added.
