Snow could fall in the Blue Mountains from Wednesday with temperatures forecast to dip by as much as 10 degrees below average in parts of NSW by Thursday.
A cold front is sweeping east, bringing potential thunderstorms and small hail in the Central West, ahead of a cool air mass that originated near Antarctica, triggering a drop in temperatures from the Victorian border to Queensland.
Areas above 800 metres elevation could see snow on Wednesday and Thursday while wet snow, or flurries, could dust places as low as 500 metres.
Bureau of Meteorology meteorologist Melody Sturm said some areas that could see falls are Cooma, Canberra and Goulburn in the south; Orange, Oberon and the Blue Mountains in the central regions; and up to 20 centimetres over the Northern Tablelands, including Glen Innes and Guyra.
