A pair of cold fronts coming from the south pole will bring freezing weather to eastern Australia over the weekend – with snow expected in some parts.
A pair of Antarctic cold fronts will bring subzero temperatures and snow to parts of NSW this weekend.
Sydney will experience a dramatic 10 degree drop in just a few days, with Friday’s 30C weather giving way to temperatures in the low 20s by Monday.
On the NSW south coast, temperatures will drop in two stages as the cold fronts succeed each other.
Friday’s temperatures between 22 and 25 degrees will drop to around 20 degrees by Saturday, and then down to a low of 17 on Sunday.
Not far from the coast, the Canberra region will be much colder, with Saturday morning temperatures of around 5C before the mercury will be expected to hover around the zero mark by Monday.
“The really cold weather will come by Monday or Tuesday, that’s because the cold front brings cooler air, and the wind needs to settle down before it gets really chilly,” the Bureau of Meteorology’s Jiwon Park explained.
Unlike the capital, the coast will be buoyed by unseasonably warm water temperatures.
“The south coast will remain a bit warmer because of the influence of the water,” Mr Park said.
“We are seeing sea surface temperatures remaining slightly warmer than usual.”
In fact, with the ocean temperature remaining around the mid-20s around Batemans Bay, and a few degrees cooler at Merimbula, south coast residents who want to stay warm may want to hit the surf.
The places where the polar conditions will really be felt include the alpine region, Monaro, the ACT, the southern tablelands and parts of the central tablelands like the town of Oberon.
“In parts of those areas we may see temperatures dropping down to below zero degrees during the early part of next week,” Mr Park said.
“There might even be some snow in some parts.”
In the Southern Alps, the snow level could drop below 1200 metres above sea level.
Where it doesn’t snow, the next few days are expected to be drier overall then the beginning of the week, Mr Park said.
“We’ve been under the influence of a moist easterly, and with the passage of the consecutive cold fronts from Friday to Sunday, there’ll be a replacement of that moist easterly by a cooler and drier southerly wind,” he said.
“It will be very dry.”
