Hotham and Buller both recorded their lowest maximum December temperature since 2013 with 0.8 and 1.1 respectively. Monday is expected to be even colder with a top of zero forecast for both destinations.
Hotham photographer Chris Hocking said even more snow was expected overnight and could continue.
“We’re expecting up to 10 centimetres to fall tonight at Mt Hotham which is certainly a rare event at this time of year,” he said.
“Who knows, will we see a white Christmas for 2019? You just never know, but it would be special for a novelty factor.”
While uncommon, Mr Hocking said snowfall in summer wasn’t unheard of.
“In the High Country summer snow is a rare event, however from time to time the strong weather patterns from the Southern Ocean break through the normal cycle,” he said.
“I’ve seen it snow in every month of the year at Mt Hotham and Falls Creek.”
Melbourne also shivered through a cold, dreary start to summer, with the mercury topping just 16.8 and Melbourne Park with 2 millimetres of rainfall recorded since 9am.
Monday won’t be any warmer, with a top of 15 expected and the temperature isn’t predicted to rise above 20 until Thursday.
