A powerful blast of cold air from Antarctica has plunged much of the country into winter-like chill, but warmer weather is on the way later this week.
This weather system has brought below-average temperatures to Tasmania, Victoria, New South Wales, South Australia and Queensland.
“Right now, we have a high pressure system that’s basically blocking all that cold air over Australia and circulating it,” he explained. Weather zone meteorologist Maryam Al-Ansari.
‘And that’s why we’re seeing such cold temperatures right now.
‘High pressure systems generally mean the air is super stable, we don’t have those clouds at night that can insulate the Earth from moving all of its daytime heat.
‘So we have very cold nights and we wake up to frost.’

The cold front is due to Antarctic air from last week being trapped in a high pressure system, which causes it to circulate across most of the country (weather map in the image)
Sydney is set to remain cold for the next two days. On Tuesday morning, the city recorded temperatures of 9.3°C, while in outer suburbs such as Campbelltown temperatures dropped to just 3°C.
The mercury will rise on Thursday, creating ideal conditions for forest fires.
“Right now, we’re starting to see winds pick up as high pressure moves eastward; that movement will start to bring heat from central Australia.”
“We have an extreme fire danger rating,” Ms. Al-Ansari said.
“We are expecting temperatures of between 20°C and 25°C on Thursday and that will be accompanied by an increase in wind speeds as well.”
Melbourne has been warmer than other east coast cities due to its cloud cover combined with northerly winds, but could experience some scattered showers.
The high pressure system will reach Brisbane today, creating strong winds along the coast.
However, temperatures are expected to rise and possibly reach 30°C on Sunday.
“We’ll see more cloud cover and it will be 2°C cooler than average for this time of year, but temperatures look set to rise over the weekend,” Al-Ansari said.
But cold weather has hit Tasmania, with Tuesday morning’s 8.7C feeling like 1C due to “quite intense” wind gusts over Tasmania.

While other cities will begin to warm up over the next two days, Canberra will remain cold. A new cold front arriving on Thursday will push temperatures even lower.
On Tuesday morning, temperatures in Canberra dropped to a freezing -2.4°C, and on Wednesday morning they are expected to be around 0°C.
Perth is experiencing higher than average temperatures, but they are expected to drop next week.
Meanwhile, Darwin continues its typical tropical weather pattern ahead of the rainy season, with temperatures reaching over 30°C this week.
