It was so cold in the Northern Territory that students at Ross Park Primary School in Alice Springs got to see icicles forming on trees in the schoolyard.

Tasmania’s capital dropped to minus 0.2 degrees before 5am today, making it Hobart’s lowest temperature since 2013.

This morning was also their third coldest morning in the last 20 years.

While cold weather is a given in winter, the particularly chilly conditions this morning were due to a dry air boost in Tasmania and the NT.

The dry air allows temperatures to drop further before the condensation produces fog.

Dryness of air is measured by something called the ‘dew point,’ the temperature at which air must cool to cause condensation. Lower dew points allow for more overnight cooling.
