Grey nomads travelling in the east have seen temperatures plunge this week, and many have taken the hint and are charting an unexpectedly early course for the north.
The Bureau of Meteorology says a very strong and slow-moving high-pressure system is sitting in the Great Australian Bight at the moment and that’s dominating Australia’s weather pattern.
The air around a high-pressure system spins anticlockwise and, in the east, the wind is being drawn from sub-Antarctic regions of the Southern Ocean. According to the ABC this means it is blowing from the southwest, directing cold air across Tasmania, Victoria, NSW and even Queensland.
That flow, which comes in the wake of a series of cold fronts now east of Australia, has reportedly kept the southeast chilled for days, with snow falling as low down as 500 metres in Victoria and 300 metres in Tasmania on Wednesday.
So, it’s doonas and heaters time for those hardy travellers caught out by the cold snap.
A high-pressure system generally means sunny, settled weather, so most of Australia will be dry and clear.
