Victoria and southern NSW are experiencing their coldest days of the spell today.
Eastern parts of the country are expected to shiver throughout tomorrow.
“Chilly mornings will take hold into the weekend as this polar airmass slowly dissipates and high pressure brings clearer skies and lighter winds,” Weatherzone meteorologist Felix Levesque said.
The polar blast brought snow to some parts of Victoria today including Mount Macedon, Mount Kaye, Mount Buangor, Mount Elizabeth, Mount William and Mount Stanley.
“Due to high winds, airport operations may be affected throughout the day,” a spokesperson for Sydney Airport said.
“We recommend passengers check the status of their flight with their airline before travelling to the airport and we thank passengers for their patience and understanding.”
