Unlike the rest of the nation, winter is sticking around in Tasmania with some places seeing their coldest September nights in more than half a century. The last three nights have been unusually cold across much of the state as a cold airmass left behind by a cold front which brought snow as low as 200 metres earlier in the week combined with clear skies and light winds. In Hobart, the last three nights have averaged lows of 1.6 degrees, the city's coldest triplet of September nights since 1959. This also includes a bone-numbing 0.6 degrees on Friday morning, the coldest September night in as many years. In the Upper Derwent, Bushy park averaged almost -3 degrees over its last three nights, its coldest triplet of September nights in 51 years of records. This included -3.7 degrees on Friday morning, equaling the September record set in 2008. In the Midlands, Tunnack has averaged almost -5 degrees the last three nights, its coldest triplet of September nights since records began in 1997. Other places including Geeveston and Lake Leake also saw their coldest triplet of September nights since their records began 22 years ago. Another chilly night is likely tomorrow morning over some parts, however nights will become much warmer from Sunday as it becomes windier, cloudier and wetter.
