That was how Friday panned out in Liawenee, in Tasmania's Central Highlands when it recorded a new state low.

The tiny town, which had a population of three at the 2016 census, is known for its frigid conditions. But Friday? Well, Liawenee outdid itself.

At 6.01am on Friday, it was just -14.2 degrees, the Bureau of Meteorology said.

It provisionally represents the coldest temperature ever recorded in the state, topping the previous record seen 37 years ago.

It was on June 30 in 1983 that temperatures of -13 degrees were detected at Tarraleah Village, Butlers Gorge and Shannon, all in the state's Central Highlands.

BoM supervising meteorologist Simon Louis said the bureau's climatologists would be following quality control protocols to confirm that the Liawenee temperature was legitimate.

"We have spoken to [the climatologists] this morning and they have looked at it and they do think that it probably is a legitimate temperature," he said.

The freezing cold temperature was caused by the remnants of the cold air mass that saw Launceston blanketed in snow on Wednesday.

"The snow is still on the ground up at the Central Highlands and up around Great Lakes so that helps the temperature drop," Mr Louis said. "And we've also seen clear skies and very light winds overnight - that also just really helps that temperature drop down really quickly."

Mr Louis said that when the previous record was set in the '80s, there was no weather station at Liawenee.

"So it's possible on that day in 1983 it would have been colder at Liawenee," he said.

"One thing that is quite interesting with this particular minimum overnight last night was that Liawenee dropped down to -14.2 but at Casey Station in Antarctica it only got to -12. So it was actually colder in Liawenee than it would have been at least in Casey in Antarctica last night."

James Johns, who manages the Great Lake Hotel and the Great Lake General Store at Miena (about 13 kilometres south of Liawenee), said residents of the Central Highlands were accustomed to "layering", insulating themselves with thermal tops and bottoms to protect against the cold - which many of them had grown to embrace.

"Today, we woke up, it was beautiful, clear skies," he said. "Not a cloud in the sky, turquoise blue, sun belting down, Swan Bay was iced over, Shannon Lagoon was under about an inch of ice and there was half a metre of snow everywhere.

"It's just fantastic."
