Icy blast results in snow in two states with more on the way

Parts of New South Wales and Victoria have woken up under a blanket of snow as an Antarctic blast sweeps across the two states despite winter supposedly coming to an end.

Snow has fallen in regional Victoria and the NSW and ACT border overnight with more forecast for the NSW Central West later today.

Weatherzone reported snow fell 300 metres above sea level in Tasmania, 500 metres above sea level in Victoria, and 700 metres above sea level in southern NSW.

"Some super cold air has enabled snow to fall to much lower levels," Weatherzone said.

Snow is forecast for Orange and Oberon, in the NSW Central West, this afternoon with the freezing temperatures also expected to reach areas of Wollondilly tonight.

But in good news for ski enthusiasts, a fresh 20 centimetres of snow coated the Snowy Mountains overnight.

Meanwhile in Canberra, temperatures dropped five degrees in less than an hour this morning.

Snow is forecast in ACT areas 700 metres above sea level.

Weatherzone said a flurry of snow in Canberra isn't "out of the question".

Christie Johnson from the Bureau of Meteorology said the cold front had moved through Victoria, Tasmania and South Australia and on to NSW today.

Weather warnings for damaging winds have been cancelled, but not before gusts of 100km/hr were recorded through the Victorian alps.

"As that front moves through north-east NSW today we could see thunderstorms develop, and some of those do have the potential to become severe and produce damaging wind gusts and large hail," Johnson said.

"There is a lot of cold air behind this front so there are warnings out for Tasmania, a road weather alert for icy roads and also a bushwalkers alert for low-level snow, and of course lots of floods warnings as well."

So far the flood warnings are "mostly minor to moderate" but Johnson urged people in affected areas to keep an eye on updates.

The cold front isn't expected to linger but will clear NSW today and is expected to develop into a low-pressure system off the coast, bringing some extra coastal rainfall tonight and early tomorrow.

"But it will clear away tomorrow pretty quickly, and then we have some pretty nice weather coming for the end of the week and for the weekend," Johnson said.
