Three states are experiencing a cold front bringing snow and low temperatures but experts have predicted where and when another arctic blast will hit.
A polar blast which brought heavy snow and temperatures as low as -8C to NSW and Victoria during the past 24 hours is set to be followed by another arctic cold front this weekend.
In NSW, Tamworth dropped to -2.6C this morning, its coldest September morning in nine years, while the Thredbo top station was -4.2C only a day after it measured -8C.
At Victoria’s Mt Baw Baw, which is currently 2C, some 28cm of snow has fallen in the past 36 hours.
Weatherzone’s Joel Pippard said the polar blast had frozen large part of NSW and Victoria.
A polar blast is when cold air comes straight from Antarctica in the south and does not have time to warm up.
Moisture from that front is currently trapped around the Snowy Mountains and great dividing ranges, causing severe cold weather and snow.
“This was a fairly strong polar blast, which are common during winter but less common in spring,” Mr Pippard told NCA NewsWire.
NSW residents woke to cold temperatures on Wednesday including numbers as low as 5C were in Broken Hill and 6C in Dubbo while most of Sydney is experiencing windy 11C.
Overnight, there was snow recorded on the ranges at Bathurst, Oberon and Guyra.
Bureau of Meteorology experts say NSW will warm up to above average temperatures on Thursday and Friday before dropping 10C on the weekend.
In Sydney, it will be 27C on Friday, then 21C on Saturday and 18C on Sunday.
“NSW is currently experiencing a cold front with temperatures more like winter than spring,” duty meteorologist Hugh McDowell told NCA NewsWire.
“We have seen some snow, only across southern ranges.
“The state will warm up for a couple of days before another cold front moves through later on Friday.
“Thursday and Friday will see temperatures about 4C to 6C above average but then it will drop to about 5C below average through the weekend.
“Sunday will be when bulk of the state cools down.”
However, that will pale in comparison to Victoria and Tasmania, which will both be hit by another polar blast.
Another cold front is expected to move in on Friday.
“There could be fairly decent snowfalls in the Victorian alps and the Tasmanian highlands,” Mr Pippard said.
“Southern Victoria should be pretty cold this weekend, as well as the eastern and northern coasts of Tasmania. It will also be quite windy in both states.”
