The New South Wales ranges will be painted white on Friday as snow showers push their way north. A low pressure system tracking across the state's south on Friday will draw a pool of cold air and moisture up from the Southern Ocean. Temperatures will be cold enough over the Northern Tablelands by Friday afternoon to turn rain into snow. Snowfalls are expected to reach as low as about 1200 metres on the Northern Tablelands and down to about 900 metres further south. Guyra would be a chance to see some snow. Towns in the Central Tablelands, including Orange, Bathurst, Mudgee, Oberon and Blaney are likely to receive snow, possibly a few centimetres worth during Friday night and Saturday morning. Further south, some of the main ski resorts will pick up 15-30cm of snow on Friday and another 5-15cm on Saturday. Cabramurra and Selwyn should see a few centimetres more than the their eastern neighbours. Looking ahead, the low will move east across the Tasman Sea on Saturday, allowing the air over New South Wales to gradually become warmer and drier from Sunday. After some fresh snow, Sunday will be the best day to visit the slopes, with mostly clear skies and light winds.
