While Australia experienced its second driest May on record, about half of the country will experience rain during the first two weeks of June.
The onset of winter was marked by unusually warm temperatures across the country due to a broad high pressure system and northerly winds.
From Monday, however, a powerful cold front from the Great Australian Bight will cross Western Australia and move east.
The system will bring cold air to South Australia by the end of Wednesday, while cooler temperatures will hit Victoria, Tasmania and NSW later in the week.
The drop in temperatures will be accompanied by clouds, rain, storms and high winds making it feel even colder – with temperatures in Adelaide feeling 3 degrees cooler than forecasted temperatures on Thursday.

The high-pressure system moving up the west coast is followed by a trough that moves every week for the next three weeks and brings rain.
Weatherzone meteorologist James Rout told Daily Mail Australia that a number of weather systems are paving the way for rain in areas of south-west, south, south-east and east Australia over the next seven to 10 days.
“We have a high-pressure system, which is east of Australia, and what that does is pull moisture from the Coral Sea and the Tasman Sea, making it ready for rainfall,” Rout said.
“The system we currently have is a weak valley over the interior in the east of the country, which will bring some rain to Victoria on Monday and Tuesday.
“But the main rain bank system is a cold front expected in the middle of the week, which is currently in Western Australia.”
Mr Rout said the cold front is bringing showers and storms to the southern parts of Western Australia with widespread rainfall of between 20 to 30mm and 50 to 80mm of rain for areas around Perth.
Perth is forecast to receive up to 80mm of rain on Wednesday, with a particularly heavy downpour of 20 to 45mm on Monday and up to 35mm of rain on Tuesday.
Wednesday is also marked by intermittent showers that will ease towards the end of the week.

The two rainfall systems will drench much of South West, South, South East and East Australia over the next seven to 10 days
The sky will appear intermittently before another trough system moves through the southern and eastern parts of the country.
Light showers are expected in Adelaide early in the week but could develop into heavier downpours with 8mm to 25mm of rain forecast for Wednesday.
While Thursday could also bring possible showers with around 7mm of rain expected.
Mr Rout said inland NSW could be lashed by twice the amount of rain normally expected for the month of June.
“In the NSW, the system coming through Wednesday and Thursday could bring 20 to 40mm of rain, with more rainfall in smaller areas caused by thunderstorms,” Rout said.
‘Mean rainfall for June for inland NSW is 10 to 25mm. There will be at least a month of rain and possibly twice as much.’
About 15mm of rain on Monday and 20mm on Thursday is forecast for Parkes, Condobolin could see 25mm on Thursday and Cobar is expected to get 30mm on Monday and then another bought rain to 20mm on Thursday.
Sydney could receive one or two showers by Tuesday, with Thursday expected to be the wettest day.

Brisbane will also have to deal with a few showers in the coming days, which will disappear from Tuesday.
Hobart will remain dry on Sunday and Monday, but showers will fall from Tuesday, with up to 9mm of rain forecast for Thursday in the capital.
A few showers are forecast to pass over Melbourne on Tuesday and Wednesday, with heavier showers on Thursday.
Mr Rout said 60 to 80mm of rain is likely to fall in the high part of western Victoria, with more than 100mm of storms expected in some parts.
Monday should remain dry in Canberra with heavy downpours expected from the middle of the week.
Showers are forecast for Melbourne on Monday and Tuesday before the city is hit by up to 20mm of rain on Wednesday.
While parts of the country will be drenched in rain, the week will be sunny and dry in Darwin with temperatures reaching a balmy maximum of 32C.
A second, albeit weaker, cold front will arrive over the course of Saturday and Sunday, bringing a fresh burst of cold air across the country.
Despite the cold weather systems, Mr Rout said temperatures will remain well above the June average as moist air from the Coral Sea floods the country.
