The reason for more snowfall is lower than average temperatures in the alpine region than in previous years.

The average temperature in Perisher this month has been 4.4 degrees just 0.7 degrees above the long-term average.

This means snow could be seen as low as 700m, meaning parts of the Blue Mountains just outside of Sydney could see their first snow of the year.

The period of snow could last all the way until Wednesday as a low-pressure system will move over that part of the country.

It will also lead to a chilly weekend in Melbourne, with a top of just 12 degrees tomorrow and 13 degrees on Sunday.

Sydney will be a little bit warmer on the weekend, but the run of wet weather will continue early next week.

Up to 40mm of rain is set to hit the Harbour city on Monday, with a further 20mm on both Tuesday and Wednesday.
