Significant rainfall set to hit most states across Australia as mild autumn temperatures end

Australia’s mild autumn temperatures are set to come to an end over the course of this week as significant rain soaks large swathes of the country.  

A low pressure system sweeping over the east coast, Top End and southwest, will bring showers over coming days leading into the weekend.

The wet conditions could see Queensland hit with up to 100mm of rain, particularly in the southeast, while Darwin is forecast to be drenched in a dramatic end to the wet season.

Northern parts of New South Wales up to Bundaberg are tipped to be doused in 50 to 100mm of rain, with a wet weekend in store for Sydney and Brisbane. 

But other parts of the nation can expect warmer conditions as a large high pressure system ushers in calm weather, blue skies, sunshine, and mild autumn temperatures. 

Sky News meteorologist Rob Sharpe said over the past eight days ‘a bounty of heavy rain’ had seen around 500mm fall in Cairns. 

‘Showers will pick up from Wednesday and more so from Thursday,’ Mr Sharpe said, News.com.au reports.

‘Over the next eight days there will see consistent rain for the coastline of southeast Queensland and northeastern New South Wales. We’re talking about significant amounts of rainfall in those areas.’

On the other side of the country Perth’s unseasonably warm autumn weather will come to a sudden halt mid-week as the temperature plummets by up to 10 degrees.

On Thursday a cold front will sweep across the city with the following day’s temperatures only set to reach 24C with the chance of a storm.

Both days of the weekend will hover around the 20C mark, nine degrees lower than the mercury on Monday. 

While Canberra and much of the Australian Capital Territory is expected to be a frosty 1C on Tuesday and 2C on Thursday, there won’t be any rain to speak of in the region. 

A ‘dribble’ of rain is expected in Melbourne and Hobart – although the temperature is expected to be an agreeable 20C for the former and mid-teens for the latter across the weekend – while Adelaide can expect highs of 25C across the week.
