It was cold as ice
HEATHCOTE might not be in the running for any silverware in the football or netball department, but the town can lay claim to being the coldest place in the Macedon Ranges this year.
Macedon Ranges Weather (MRW) recorded an overnight low of -6.2C in Heathcote on August 29 – beating the previous regional low in 2018 of -5.1C recorded near Ashbourne on July 14 – while Castlemaine came in second at -5.4C and Lancefield clocked -4.9C to finish third.
Eighteen automatic weather stations, including the Bureau of Meteorology’s station at Redesdale, went below -4C that morning, with Heathcote reporting the record low at a private online weather station on Wright St.
The air temperatures were recorded on automatic weather stations at a height of 1.5-2 metres and, according to an MRW spokeswoman, an unusually cold night was predicted in advance. ‘‘We knew that the atmosphere was ripe for extreme overnight lows, as a low in the Tasman was sending cold upper air into Victoria which would combine with a high pressure system and a cloudless night,’’ she said.
The Bureau of Meteorology’s senior climatologist, Blair Trewin, said while it was unusual to have such a cold snap so late in the year there were a couple of reasons.
‘‘One is that the basic underlying air mass is pretty cold,’’ he said. ‘‘But also because we had clear skies over Melbourne and light winds – that meant it was pretty well set up for overnight cooling.’’
