Sunday is expected to be the coldest day yet this year; temperatures are tipped to max out at 8 degrees.

While snow was forecast to fall above 800 metres on Saturday, and above 600 metres on Sunday, that was revised to above 1000 metres on Sunday.

That meant suburbs in Canberra missed out.

However alpine areas of the ACT copped a dusting and Corin Forest gained a few centimetres overnight.

While there wasn't enough snow on its toboggan run to open its formal snowplay area, the resort said there was plenty around its lodge for people to enjoy for free.

The Brindabella Range also received an icing, as did parts of the Namadgi National Park, including the Stockyard Spur walking trail.

The resorts south of Canberra were more fortunate. Perisher received five centimetres overnight and Thredbo received 15 centimetres.

A Bureau of Meteorology meteorologist said the cold snap was driven by a high pressure system from the west, and there was the possibility of more snow on Monday in areas above 1100 metres.

From Tuesday, this high pressure system coupled with a low pressure system moving east would bring showers along the NSW coast as well as the adjacent ranges, but it would be "just showers, not snow".

Canberra would dry out from Wednesday, with partly cloudy days and top temperatures of 13 - just above the average maximum for June - for the rest of the week.

The minimum temperature will be 2 degrees on Monday and Tuesday, just above the average minimum for this time of year of 1 degree. However that will dip to 0 from Wednesday onwards.

This weekend was not the first time is has snowed in the Canberra region this winter.

The Namadgi National Park was blanketed more than a month ago, although the low for May was 12.3 degrees at the airport.
