Meteorologists are warning that a "strong blast of Antarctic air is expected to send a shudder all over Victoria" on Melbourne Cup Day.
Next week, the southern states will be hit by severely low temperatures, strong winds, showers, and maybe tiny hail.
The "dynamic" low-pressure system that pounded Queensland, New South Wales, and Victoria is moving south towards Tasmania, but experts are warning of another weather catastrophe forming in Antarctica.

According to Weatherzone, the south-eastern states will be slammed by a "bitterly cold arctic blast," causing temperatures to plunge.
It will bring high gusts, rains, and maybe some hail - just in time for the Melbourne Cup, as per 9News.
"It's going to be a very chilly and occasionally rainy week," Weatherzone meteorologist Brett Dutschke said.
Temperatures will be five to six degrees cooler than usual for the time of year, much more characteristic of August.
The warning comes after a single weather event slammed Melbourne's north-east overnight night.
Flash flooding was produced by two hours of heavy rain at Lilydale, a neighborhood less than 50 kilometers from Melbourne's CBD.
The system resulted in around 200 calls for assistance and 11 flood rescues.
A local claimed he's never seen anything like the rapid floods. "Honestly, it was comparable to a battle zone; there was a mess everywhere," he told Today.
After a rainstorm, similar events played out in the NSW town of Cooma.
As the town flooded with shin-deep water, homes were separated and routes were restricted.
According to accounts, this is beginning to subside.
The low-pressure system that has caused the severe weather is now travelling south across Victoria and into Tasmania, where it is thought to be "deepening."
During the following 48 hours, the system will intensify wind and rain over Tasmania.
Weatherzone predicts 100 to 200 mm of rain in the state's east during the next two to three days.
A flood watch is also in effect for the North, North East, Derwent, and South East Catchments of the state.
Residents in Victoria could expect further rains over the next three days until the system dissipates.
The rainy weather is expected to cease soon, with the Bureau of Meteorology (BoM) indicating that La Nina will decrease in early 2023, with the Indian Ocean Dipole "rapidly withering" in late Spring.
The warning comes as extensive flooding in New South Wales and Victoria persists.
On Tuesday, Prime Minister Anthony Albanese said that 25,000 Australians have received Commonwealth relief funds as a result of the recent flood.
As of 6 a.m., 107 flood warnings were in effect in NSW, with 77 in Victoria.
Twenty and six of these are classified as emergencies.
"It's going to be a very chilly and occasionally rainy week," Weatherzone meteorologist Brett Dutschke said, as per news.com.au.
There will be enough rain in the run-up to the cold outbreak to make the track soft, if not heavy, and the grassy expanses of the Flemington lawn may mud in patches and swallow up high heels.
Top temperatures in Melbourne will only reach around 15 degrees on Tuesday, but breezy winds and showers will make it feel even colder, with similar conditions expected for Oaks Day on Thursday.
The polar blast will reach the southern states, bringing freezing temperatures to Melbourne.
Tasmanians will not be able to escape the unpleasant weather until long until next week, with rainy, windy, and chilly conditions predicted for the state until next Wednesday.
The feared weather system that caused torrential rain and deadly flooding will pass in the spring, but summer will bring new difficulties and unexpected projections.
As the negative Indian Ocean Dipole (IOD) in the west comes to an end, the La Nina weather phenomenon in the east will continue to produce damp weather over the Christmas season and beyond.
But, in order to grasp what this implies in terms of weather during the silly season, we must first define all of these meteorological occurrences.
Climate drivers are events induced by the waters surrounding us and the atmosphere above us, all of which have the potential to significantly influence the weather.
The IOD has minimal effect on the climate around us in neutral years, while negative years bring copious rains to the nations on the eastern side of the Indian Ocean and droughts to the west.
A positive IOD event has the opposite impact, increasing the likelihood of drought and, in severe circumstances, raging bushfires.
Consider the positive IOD event in 2019, when Australia saw one of its most destructive wildfire seasons on record.
