Snow will continue to fall on parts of the ACT on Thursday but Canberra is likely to miss out.
Heavy rain falling in Victoria and northern NSW was unlikely to reach the ACT towards the end of the week, reducing the likelihood snow would fall in the city.
The Bureau of Meteorology has predicted continued snowfall for the Brindabellas and Mount Ginini on Thursday.
Meteorologist Helen Reid said the Brindabellas would have already collected a "nice white blanket".
"Down into the city itself, it is rare for snow to fall there," she said. "We're always hopeful, we've always got our fingers crossed.
"There could be more half-frozen rain but as for snow itself, it is looking less likely."
This week's cold front bought a dusting of snow to parts of the ACT's south on Wednesday, with conditions leading to closures in parts of the Namadgi National Park.
Snow was seen in elevated parts of the ACT such as the Brindabellas and Mount Ginini throughout the day.
Meanwhile, hail was seen in parts of Canberra's south including Fyshwick, Symonston and Hume.
It comes as falls were also spotted in areas across the border in NSW around Michelago and Nimmitabel, with some roads out of Jindabyne closed except for vehicles with snow chains.
The weather system has brought with it bumper falls for Thredbo and Perisher ski resorts ahead of the official start to the ski season this weekend, with several centimetres of snow being recorded.
Further falls are expected on Thursday.
Forecaster Helen Kirkup from the Bureau of Meteorology said the majority of snow from the weather system had fallen in areas to Canberra's north, such as towns in the central tablelands.
Ms Kirkup said while snow was more likely to be seen in the ACT around Mt Ginini and the Brindabellas, some falls could happen lower down on Thursday in the right circumstances.
"It is colder to the north of Canberra, but it's probably likely there will be some snow falling on Wednesday night into Thursday morning, but how low is uncertain," she said.
"There is a low chance of it falling in the suburbs. Mount Ainslie would be lucky to get something.
"Whether it's cold enough to see that snow, I'm not sure, but there is a low chance."
The forecast of snow and rain prompted the closure of several roads in the Namadgi National Park, along with the visitor centre.
Corin Road past the Corin Forest Mountain Resort will be closed due to the weather, leading to the closure of Square Rock, Corin Dam, Bulls Head, Mount Franklin and Mount Ginini.
Further closures in the area are a possibility if the weather deteriorates further.
The southern end of the Googong Foreshore will also be closed until at least Saturday.
ACT Environment Directorate executive Ian Walker said large parts of the national park had been closed for safety reasons.
"We are advising all Canberrans to avoid these areas as we see high amounts of rain and snow predicted over the coming days," Mr Walker said.
"Namadgi National Park is a part of the Australian alpine area, so visitors need to be aware that conditions can change and deteriorate very quickly.
"If you are travelling in or around ACT parks, please make sure you are prepared for a weather event."
A low of minus 1 is forecast on Thursday, with showers continuing, reaching a top of 10.
The weather system that's responsible for the wintry conditions is set to move out to sea late on Thursday or early on Friday.
