The Blue Mountains are set to become white tonight as the snow level continues to lower over the New South Wales ranges. Cloud has been widespread across the state today, keeping temperatures very low, even for July. Most locations across the Central Tablelands district were between three and seven degree below the monthly average. Bathurst, for example, only saw the mercury reach six today, the hilliest day in a year. In fact, a day this cold only happens once or twice a year in Bathurst. Rain has also been a factor, working in concert with the cloud to prevent any real heating. However, falls have stayed fairly light. Snow is now looking to become a reality, with the snow level even dipping below 1000 metres as the coldest upper air passes overhead during the early hours of the morning. Already there have been reports of sleet at Sunny Corner. Avid winter photographers should get ready for blanket of snow in the more elevated regions of the Blue Mountains. Cloud should clear during the morning, allowing snowfalls to melt, so perhaps the early the photo, the better.
