The ski resorts closest to Canberra could receive up to 20 centimetres of snow this weekend.

But it gets better: perfect snowmaking conditions are forecast for next week too.

Sunrise at Perisher on Thursday morning.

Weatherzone senior meteorologist Rob Sharpe said the weather systems currently moving over the mountains meant they were looking at peak snowfall on Sunday.

"So it's a complex low pressure system that has been moving across southern Australia, so with that there was a front and a few troughs that moved across the ranges. They moved through from Monday," Mr Sharpe said.
