Despite a forecast run of freezing mornings until Friday, Canberra's weather during the coming week is expected to be fairly stable, and close to the July averages of about zero degrees in the morning, and about 11 to 12 degrees during the day. Last year, Canberra started July with a run of seven consecutive nights below minus 4 degrees, between July 3 and 9. But Bureau of Meteorology forecaster Magdalena Galos-Lorrenc said Canberra's coldest night this week would probably be a rather balmy minus 3 degrees, during a week of cool nights but slightly warmer-than-average days.

"Looking at the next week, this high pressure system from the Bight is moving eastwards, which means by Tuesday evening the high pressure centre will be somewhere between Victoria and NSW," she said. "Ahead we've got a few clear and pretty cold nights, at least here in Canberra."

Ms Galos-Lorrenc said Monday night and Tuesday morning were expected be the coldest of the week as the high pressure system moves over, with possible frost and fog.

The cool wind during the weekend brought some snow to the southern and western reaches of the territory. Mount Franklin Road was closed on Sunday due to overnight snow, and Territory and Municipal Services urged Canberrans to stick to established snow recreation areas.

"Residents wanting to experience the snow first-hand are strongly encouraged to consider visiting an established snow recreation area, such as Corin Forest, rather than informal areas accessed by Brindabella Road and Boboyan Road," TAMS said. There was good snowfall at the NSW ski resorts in the Snowy Mountains during the first weekend of the ACT school holidays.

Thredbo recorded about 60 centimetres of snow from Friday morning until to Sunday evening. The resort opened an additional 10 runs on Sunday, and hoped to open more lifts and terrain on Monday.

Perisher received 37 centimetres of snow during the seven days to Sunday, a boost to snow depths which were recorded at about 28 centimetres last Thursday.
