Series of cold fronts sends temperatures plunging
Systems will bring rain, wind and icy conditions

A series of relentless cold fronts will bring icy temperatures, rain, damaging wind gusts and even snow to Australia's southeast this week.

The first in four cold fronts arrived in southwest Western Australia on Sunday and delivered rain and wind gusts of over 120km/hour to the region.

Possible snowfalls between 10cm and 30cm are expected over the alpine regions, particularly in Victoria, with strong winds and rain to impact low-lying regions.

'Strong to damaging winds will be the main impact from this weather front,' the Bureau of Meteorology's Dean Narramore told Daily Mail Australia.

The forecaster said residents in coastal and elevated parts of South Australia, Victoria and southern NSW needed to remain vigilant amid powerful wind gusts.

'Those winds will be strong enough to bring down trees and powerlines and may cause property damage,' he said.

'A trampoline may go flying so tie down items.'

A stronger cold front is expected to arrive on Wednesday, which will bypass southwestern WA, but directly impact the southeast with cold, windy weather.

Snow could fall on Mount Lofty, just 25 minutes' drive from the Adelaide CBD.

'The airmass will likely be cold enough for snow in SA's Flinders Ranges later on Wednesday, should sufficient moisture make it that far north,' Weatherzone said.

The heaviest falls of snow will impact the alpine regions in NSW and Victoria where 20cm to 40cm are predicted, with snow falling at elevations as low as 800m.

Elevated areas like the NSW Central Tablelands can also expect snowfalls.

Areas east of the Great Dividing Range will be spared from the bleakest weather and Sydney should be cool but dry all week.

In the north of the country, a high-pressure system is dominating the weather patterns and making way for a clearer, dry week in much of Queensland.

Much of the area could be 'completely cloudless' for the week.
