While Canberra started the week with a top temperature of just 12 degrees and rain on Monday, the cold weather really took hold in the higher regions, with snow falling at Perisher Resort and parts of Namadji National Park.
The Bureau of Meteorology's Sean Carson said 26 millimetres of rain fell in the ACT in the 24 hours to 9am Monday, before a further 12 millimetres of rain during the afternoon.
Easterly winds peaked at 44km/h shortly after midday.

Remembrance Day commemorations at the Australian War Memorial on Monday morning were marred by persistent rain, leading many speakers and those laying wreaths to use umbrellas throughout the service.
An ACT Policing spokeswoman confirmed there were no major accidents during the morning or evening peaks, and complimented drivers for being ''cautious and responsible''.
Mr Carson said snow fell in the highest parts of the Brindabellas and the Snowy Mountains.

''It's less likely, but we do get snowfall occasionally in the ACT in November,'' he said. ''But after a couple of 30 degree days back-to-back last week, it's a hell of a change to only make it to 12 degrees.''
In the Namadgi National Park, Mount Franklin Road was closed at lunchtime at the Mount Franklin visitors' shelter after 30 centimetres of snow fell across 24 hours. The visitors' shelter is 1600 metres above sea level.
National Parks and Catchments regional manager Brett McNamara said he had never experienced a shift from heat to cold of such magnitude in so little time.
''I've been with the parks service for 23 years and in my experience I've never been at a fire [standby] in one week and had snow the next,'' Mr McNamara said.
He said there was further snow at the visitors' centre after lunch on Monday.
The temperature at Perisher Resort reached one degree on Monday. About 35 centimetres of snow fell, leaving a thick cover.
Thredbo Village had a peak of 3 degrees and recorded 12 millimetres of rain. Showers were expected to fall as snow above 1700 metres on Tuesday.
The temperature in Canberra is predicted to reach 19 degrees on Tuesday, and isolated thunderstorms are expected to bring up to 15 millimetres of rain.
The temperature is tipped to peak at 20 degrees on Wednesday, with isolated showers and thunderstorms in the morning.
Mostly sunny conditions are forecast for Thursday, with a top of 22 degrees.
Showers should return on Friday and are tipped to continue during the weekend.
