Snow has fallen along the length of the Victorian and New South Wales ranges, affecting Castlemaine, the Blue Mountains and even Armidale. A powerful cold front crossed Australia's southeast yesterday and was followed closely by a trough with plenty of cold air and a bit of moisture. Yesterday afternoon the trough crossed VIC, with showers falling as snow around Trentham, Castlemaine and Mt Macedon before it dropped up to 20cm of snow on the major Victorian resorts. Overnight the trough continued moving north, increasing snowfalls at Thredbo and Perisher, which now have snow depths close to two metres overall. However, the bigger news is where the snow fell this morning. As the trough continued moving north it was starting to run out of moisture as usual, but the air was cold enough and wet enough to bring a covering of snow in Orange and Bathurst and flurries in Lithgow and Medlow Bath. In Blackheath the light snow turned to ice on the roads, leading to the closure of part of the Great Western Highway. The trough kept moving north just before sunrise with light snow falling on the Northern Tablelands in Guyra and Armidale. For Armidale this is the first snow of winter, after it missed out with all of the powerful cold fronts that winter has brought. Now the temperature is climbing again and any light snow that fell on the ground is nearly gone. Only the ski resorts and a few parts of the tablelands will have snow remaining by tomorrow. It will be at least a week and a half until snow falls on the NSW central or northern tablelands, and it could be even longer.
