Brace for the 'Antarctic blob': Coldest day of the year is set to hit the east coast with Sydney directly in the firing line - here's how long it will last
- New South Wales and Canberra will bear the brunt of the chilling temperatures
- Strong gusts of wind in excess of 90km/h will make it feel colder than it really is
- Sydney's maximum temperature will reach a mere 16C with a minimum of 8C
- Snow will fall in places just 500m above sea level for the first time in 15 years
Parts of Australia will shiver through the coldest day of the year as a deep low-pressure trough batters the east coast with wild winds and chilly temperatures.
The trough has developed over south-east New South Wales during the past 24 hours, extending into the Southern Ocean, and is likely to persist until Monday.
Weatherzone's Ben Domensino described the system as an 'Antarctic blob' that will drop snow across swathes of ACT and the NSW Central and Southern Tablelands.

Sydney's maximum temperature will reach a mere 16C with a minimum of 8C on Saturday and winds of up to 40km/h

Jane Golding from the Bureau of Meteorology (BOM) said the 'unusual weather event' will send temperatures plummeting to 10C below average on Saturday.
'This could be the coldest day with the windchill factor we've seen all year,' Ms Golding said.
'Over the next few days we're expecting that system to really bring some high winds, some really cold temperatures and also some snow to quite low levels here in New South Wales that we don't normally see.
'We've already seen the start of that with some pretty gusty winds develop over a lot of NSW, those winds kicked up some dust over western NSW.'

Temperatures will plummet to a freezing 5C at Goulburn, Katoomba, Canberra and Orange, but the strong winds will make it feel more like -3C to -5C (pictured: Thredbo)
