Snow has settled in some of Hobart's suburbs after a flurry overnight, reaching down as low as 150 metres in the state's south, with more chilly nights on the way for Tasmania.
Luke Johnston from the Bureau of Meteorology said a burst of cold air came over Tasmania behind a cold front that crossed the state on Sunday, bringing south-south westerly winds.
He said the lowest temperature in the state was -6.5 degrees Celsius, recorded at the pinnacle of kunanyi/Mount Wellington, with an apparent temperature of -20C at midnight.
"[It is] a very cold outbreak for the state, with snow showers down to low levels — nearly sea level — with a few reports of snow flurries, so not settling, to about 20 metres above sea level in Howden," Mr Johnston said.
"For the rest of today we'll see the snow level gradually rise and shower activity, or snow shower activity, decrease throughout the day."
Hobart's expected maximum temperature today is 8C, which Mr Johnston said was "just about as cold as you can get for a day in Hobart".
"What we're left with for the rest of this week is a very cold but otherwise fine week, pretty much state wide.
Mr Johnston said the next few mornings would be "very, very cold for most of Tasmania, even for Tasmania, with widespread minimum temperatures between -2 and -4 degrees".
In Launceston, the mercury stayed above zero.
"Launceston got to around 2 degrees, which, believe it or not, is relatively warm for them for this kind of cold outbreak," Mr Johnston said.
"Launceston's going to get colder mornings throughout the next couple of days with about -3, -4 degrees expected."
Several warnings are in place, including a bushwalkers' weather alert and a road weather alert.
Ben Lomond Alpine Resort managing director Ben Mock said the mountain was covered in "perfect powder" for skiing.
In the state's north-west, Cradle Mountain Road — leading to the the tourist hotspot — has been closed due to hazardous ice and snow.
Mr Johnston said conditions would be hazardous on the state's roads, particularly for the next few mornings.
"It's very cold, the roads will be cold, there's some moisture around, the snow may melt but it will probably refreeze in places overnight causing patches of black ice to start popping up," he said.
Tasmania Police has issued specific warnings for several roads.
There is some relief in sight.
Mr Johnston said warmer winds from the north-east would flush away the cool air later in the week, with more mild temperatures expected on Sunday.
