Cold blast to sweep across parts of Australia, Melbourne expects coldest April day since 1960
A deep, polar low is forecast to sweep across parts of southeastern Australia over the next couple of days, bringing cold, wet, and windy conditions. Heavy rains are expected in some areas, while Melbourne could experience its coldest April day in 60 years.
A cold front is forming in the southern Indian Ocean, driven by a deep, polar low. It is set to bring cold, wet, and windy conditions– some of the most significant as Australia heads towards winter. The front will begin in Western Australia, but Perth will remain sunny through most of this week.
"Everything changes from Wednesday," Keris Arndt from the Bureau of Meteorology (BOM) said.
"In Victoria, we’ll see rain developing overnight on Tuesday and then spreading eastwards reaching Melbourne early afternoon on Wednesday, which will likely bring some thunderstorms before some really cold air moves over."
Tuesday expect showers in the west of #SouthAustralia tracking east ahead of a cold front. Wednesday more wet conditions with front & much cooler temps with potential for isolated thunderstorms and small hail in parts of agricultural areas.

The cold front expected to cross SE Australia this week should be preceded by a useful rain band (further to weekend rain over VIC). Conducive ocean temperatures are providing more atmospheric moisture for fronts to tap into than was seen in 2019. https://t.co/aR3QPOTGJ8 pic.twitter.com/Zjapsnhvi7

Up to 30 cm (12 inches) of snow is expected through the alpine regions of Canberra, Victoria, New South Wales, and Tasmania on April 30.
"As we head into Wednesday, we’ll start to see some significant prefrontal rain in areas where it’s desperately needed across the northern country of Victoria to the state’s northeast and then west of the divide in NSW," said Sky News meteorologist Alison Osborne,
Aside from rains and snow, hail is also in store for southeastern states, including Victoria, Wednesday onwards.

Earth behavior is normal over time. An obliquiti cycle ago we had the Laschamp event with the extinction of life that couldn’t adapt. The Neanderthal DNA with differences from our ancestors could not and disappeared from this globe. Follow the path over the Earth’s crust that the magnetic poles follow. Since the magnetic north pole passes over the LOMONOSOV ridge, I expect, as with the ALPHA ridge, that the average annual temperature will drop not only in Belgium but also in Australia. Climate change is a normal terrestrial phenomenon driven by geodynamics and the sun, but abused by IPCC lobby groups to push through their green politics
We live on a planet. An electrical sentient entity. But for the interference of humans, with their planes, ships and microwave technologies, there will be consequences for this “climate forcing”, and attempted manipulation of the weather. even selling it to the highest payer. I am quite able to accept that this Earth will behave as a planet will, cyclically, and naturally. Australia is complicit in the outcomes of their part in the global deliberate polluting, and energizing, or “microwaving” the stratosphere to exact a response. It is sickening to see the chemicals mixing above my head, and to then breathe the same mix , Always “scientists” no names, and wretched humans flying the mixing planes, and piloting ships in task force style to induce controlled weather, be it denial of rain, hazing of the sky , or the drawing in of excessive moisture, to the point of flooding. This has to stop. Then we will get decent climate change as the Earth returns to normal. Air clean, water clean, crops once again nutritious. The way it should be.
