Entire country to be hit by tropical rain bomb with a month's worth of water to fall in just a few days

Rain is set to soak every Australian state over the next week - with some locations forecast to receive a month's worth of rainfall in just a few days.

A surge of tropical moisture is forecast to cause showers across the nation from the weekend until the end of next week, according to Weatherzone.

Rain and thunderstorms will increase over the north of Western Australia over Saturday and Sunday as this moisture feeds into a deepening area of low pressure.

'This wet and stormy weather will then spread over central Australia on Monday before forming a broad rainband that will drench southeastern and eastern Australia,' a Weatherzone spokesman said.

'Some areas in Western Australia and the Northern Territory that typically receive 20-50 mm of rain in September could pick up about 50-100 mm from this event.'

Some of the falls are expected to be concentrated over next Thursday and Friday.

Over the weekend, the Bureau of Meteorology has forecast several showers in southeast Queensland , as a low pressure trough moves off the east coast over Saturday.

Meteorologist Miriam Bradbury said the eastern and northern parts of the Sunshine State would experience a warm day as maximum temperatures climbed into the 30s - particularly around Townsville, Weipa, Mt Isa and Cairns.

Inland temperatures would be slightly below average, she said.

New South Wales is forecast to experience 'patchy' morning frost across parts of the South Western Slopes - with some showers likely around areas like Albury.

'Sydney is heading for a mostly sunny (day)... tops of 25C tomorrow,' Ms Bradbury said.

'Down in Canberra - 16C and partly cloudy.'

Another cold front would lead to continued showers and gusty winds in the country's southeast, mainly concentrated on the south Victorian coast.

Melbourne is set to experience showers, with maximum temperatures of 17C.

The bureau has forecast showers over the weekend for Adelaide, which will peak at temperatures of 17C and 19C over Saturday and Sunday respectively.

Those falls are expected to ease by Sunday.

Ms Bradbury said storms would persist in northern and inland Western Australia over the weekend, but drier conditions through the more southern districts.

Perth will remain sunny and not climb beyond a maximum temperature of 25C over Saturday.

In the Northern Territory, Ms Bradbury said there were chances of showers and thunderstorms across western parts of the Top End which could 'push into the Kimberley, Pilbara and northern interior of WA' as the pressure deepens.

The sweeping showers come as the Tasmanian ski town of Mt Mawson, an hour-and-a-half out of Hobart, was blanketed by snow over the past few days.

Peter Davis from the Southern Tasmanian Ski Association on Thursday announced the ski tow would run over the weekend after an estimated 20cm of snow fell overnight.
