More chilly temps forecast after low snow

·2-min read

Southeast Australia is in for more chilly temperatures this week, as a high-pressure system strengthens and Tasmania is hit with snow in low-lying areas.

A strong cold front over the weekend pushed snow levels down to about 300m around Hobart early on Monday morning.

Snow settled as low as about 150m above sea level for brief periods on Monday, with flurries also at sea level in southern parts of Tasmania.

Hobart recorded its coldest day since August 2016 on Monday, with a maximum of 7.3C, the Bureau of Meteorology said.

Kunanyi/Mount Wellington reached minus 3.9C, the coldest maximum it has had since August 2005.

City of Hobart bushland manager John Fisher said it felt like minus 20C on the mountain on Monday when cutting winds were factored in.

"It's so close ... the mountain looks fantastic, it's got white snow on it (and people say), 'Let's go up and have a look'," he told AAP.

"When they get up there, it's a completely different world."

Mr Fisher and his team conduct daily inspections to assess conditions on the mountain, but were hampered on Monday mainly by a thick layer of ice on the road.

They reopened the mountain to the Springs on Tuesday morning, and were monitoring ice on the roads to determine how far it should be opened on Wednesday.

No fresh snow was forecast for the rest of the week, but what was already there would take days to melt away, the bureau said.

Snow would probably remain at levels above about 1200m until at least Friday.

A bureau road alert to drivers to be wary of icy roads remained in place on Tuesday for the North-West Coast, Central North, North-East, western, Central Plateau, Midlands, East Coast, upper Derwent Valley and South-East forecast districts.

"The real focus now is road conditions," bureau meteorologist Luke Johnston said.

"There's a lot of elevated roads in Tassie that have either had or still have snow on them, so limiting transport around the state."

He said there was always plenty of black ice about.

Snow levels were expected to hover down to about 800m into early Tuesday more broadly across Australia's southeast.

Minimum temperatures across large parts of Tasmania and Victoria, as well as areas of NSW and eastern South Australia, were forecast to drop between 4C and 8C below average from Tuesday.

Meteorologists were expecting widespread frost, with severe frost possible across some inland areas.

Hobart was forecast to have the chance of morning frosts until Friday, with Launceston expected to see frosts through to Thursday.

The bureau said temperatures were likely to drop below minus 2C in some inland areas.

"These very cold nights may even extend towards central Australia by Wednesday and Thursday morning as well," senior forecaster Miriam Bradbury said.
