Sydney, Melbourne, Adelaide, Perth weather: Even more rain and ‘cold season tornado’ coming for one state

Australians will endure another arctic week with the possibility of a tornado in Western Australia as large parts of the country brace for submersion.

A low pressure system will move inland and towards south-west WA and the Pilbara region, with falls of between 15 and 40mm this week.

Perth will also experience heavy rain this week. 15mm of rain is expected on Wednesday, 25mm on Thursday, before skies clear on Saturday.

The arrival of a winter cold front will bring hail and the chance of a brief ‘cold season’ tornado to south-west WA, Weatherzone’s Anthony Sharwood said.

“Thursday and Friday morning, the core of cold air and low pressure center will cross the region and develop into a low,” he said.

‘Cut-off lows are low-pressure systems that have been cut off from the westerly winds that circulate across the globe south of Australia.

“As the low brings in the coldest air, scattered thunderstorms are possible in the southwest, while small hail is likely, and there is even the chance of a few brief tornadoes in the cold season.”

The Stirling Range, in Western Australia’s Great Southern region, may see light snow this week. The chance of a heavy snow shower is greatest on Friday morning.

Parts of central Queensland received more than a month’s worth of rain in 24 hours, with wet and wild conditions expected to continue this week.

In the 24 hours to 9am on Wednesday, falls of 30 to 60mm were recorded between Mackay and Townsville, with falls of 59.8mm at Mackay Airport.

The trough will continue to bring widespread rain to central Queensland on Wednesday and Thursday, with showers spreading into the north and southeast.
