Temps to ‘plummet’ as winter is coming

It's time to fossick under the bed for you sweaters and scarfs - winter is coming.

A double whammy of cold fronts will sweep through south eastern Australian this week which will see "temperatures plummet", forecasters have warned.

Heavy bursts of rain, snow down to 1000 meters and severe frost are all on the cards.

The culprits are two fronts sweeping from west to east that will bring multiple bands of rain and snow, said Sky News Weather channel meteorologist Rob Sharpe.

"We'll be really feeling a taste of winter by the time we get to the end of the week," Mr Sharpe said.

The first band is currently in the Great Australian Bight and should reach Adelaide by Tuesday and then head into Victoria and finally parts of New South Wales on Wednesday.

That will bring some showers but it's just a precursor of the main event later in the week.

"Right behind the first front is a better event. This one is a cold front but there is also likely to be a low pressure system forming within it that will bring fairly decent rain even into parts of NSW," Mr Sharpe said.

In terms of snow, up to 5cm could fall in the Alps earlier in the week. But the second front could dump enough of the white stuff to reach 20cm deep by the weekend. That snow could fall on higher ground down to 1000m in Tasmania, Victoria, NSW and even the Central Ranges.

"The impact of the second front carries through to the temperatures which will plummet right across south east Australia with very chilly conditions by the time we get to Saturday," Mr Sharpe said.

Frosty conditions could also be a possibility on Saturday morning, with some of that severe in inland and higher areas of Tasmania, eastern Victoria, southern and eastern NSW and the ACT.
