Sydney, Melbourne, Brisbane, Perth, weather: When rain will end

Millions of Aussies are bracing for another wet week as more heavy rain and storms smash the east coast a few days from summer.

Most of Australia's capital cities will cop a soaking in the coming days as rain and storms, which have lingered around much of Queensland for the last week, push south again, extending across the Bass Strait into Tasmania.

Sydney and Canberra will see the most rain, with up to 70mm forecast for Tuesday and Wednesday.

Those in Brisbane, Melbourne and Adelaide will also need their umbrellas.

On the other side of the country, Western Australia's record-breaking heatwave is over, and we will see cooler temperatures for much of the week and some welcomed rainfall in the state's far south.

The rain and storms, which stretched almost the entire 4,000 km-long east coast last week, are due to a slow-moving weather pattern exacerbated by rising atmospheric moisture.

'The low pressure trough which eastern Australia has been stuck in for the last week still has a bit to go,' Weatherzone meteorologist Brett Dutschke told Daily Mail Australia.

'It will be at least a week until the next long dry spell comes along.

'I wouldn't be surprised if the rain hangs around for another week-and-half.'

'Most capital cities will see a mixed bag this week in terms of warmth, dryness and west  

Here's the weather forecast in your capital city this week.

Brisbane

The Queensland capital is in for a wet Tuesday with up to 15mm forecast and a few more showers on Wednesday.

There's also a possible chance of a thunderstorm on both days before a brief reprieve from the wet.

Conditions will remain throughout the week and will reach a high of 35C on Thursday.

'It will be warm and dry later in the ahead ahead of more storms from Friday onwards,' Mr Dutschke said.

Brisbane will see a wet start to summer, with 20mm predicted for Saturday and another 9mm for Sunday.

Sydney

Sydneysiders should enjoy Monday's brief reprieve from the rain before a midweek deluge develops.

The harbour city will cop a 30mm drenching on Tuesday, followed by another 35mm on Wednesday, with the chance of a thunderstorm on both days.

'There will be heavy bursts of rain, but conditions will remain humid,' Mr Dutschke said.

The rain and humidity will ease from Thursday.

Maximum temperatures will remain in the mid-20s, and a medium chance of showers this weekend.

'Hobart is in for dry and cool start to the week but there's fair chance of some rain later in the week,' Mr Dutschke said.

'Friday looks like the wettest day.'

The weekend will be cool, cloudy and overcast at this stage with a top of 19C forecast.

Perth 

West Australians have welcomed a cool reprieve from a week-long heatwave of 40C-plus temperatures blasting the state for the seven days.

Most of WA will miss out on most of the deluge smashing the other side of the country.

'There some chance of showers in Perth on Tuesday and Wednesday but most of the rain will be in the far south-west,' Mr Dutschke said.

Temperatures in Perth will remain in the mid-20s before conditions warm up later in the week for the start of summer, reaching a high of 33C on Friday.

Darwin 

The Top End's yearly wet season of high humidity, monsoonal rains and storms is in full swing.

Monday shapes to up to be the driest day of the week with only a slight chance of a shower later in the day.

'There's a chance of showers and storms in Darwin every day this week,' Mr Dutschke said.

'At this stage, it's not looking any wetter than it is at this time of the year.'

Conditions will remain sticky and humid with maximum daily highs of 33-34C.
