Sydney, Melbourne, Brisbane weather: Heavy rain to batter the country as cold front moves in - what the forecast looks like in your city

Heavy rain is set to batter large swathes of Australia as a series of weather systems usher in cool and wet conditions for parts of the country. 

A low pressure system is forecast to develop off the coast of Perth on Tuesday, bringing with it a band of rain set to fall across the south west of Western Australia. 

A cold front is also forecast to bring showers across parts of NSW, South Australia, Victoria and Tasmania, with even some snow about the high mountain peaks. 

Showers and thunderstorms will develop over Western Australia's western districts before spreading further south and east between Tuesday and Thursday. 

Total rainfall in the west and south west of the state are expected to remain in the single digits. 

However, some areas of the far south west seeing accumulated totals ranging between 15 to 50mm by the end of the week.

Weatherzone Meteorologist Ben Domensino said the wet weather is a welcome change for the state after enduring its driest seven-month period on record.  

'While there won’t be enough rain to completely eradicate the rainfall deficits from the past seven months, the wet weather will be a welcome change for the parched landscape,' Mr Domensino said. 

Mr Domensino explained there was uncertainty regarding the resulting rainfall over the eastern parts of Australia but most forecast models agree heavy rain will affect parts of NSW and Queensland.

'There is some uncertainty regarding the position of the upper-level low and the resulting rainfall towards the end of the week,' Mr Domensino said. 

'Weather patterns like this can cause several hundred millimetres of rain along the NSW coast and adjacent ranges. 

'Most forecast models agree that heavy rain will affect parts of eastern NSW, with potential for substantial falls in southern Queensland, and in western and central NSW as well.'

Mr Domenisco advised rainfall forecasts for individual locations may vary during the week, while severe weather warnings would be issued as heavy rain days approach.
