For the first time this winter, there is the potential for snow to fall along the non-Alpine Tablelands of New South Wales later today and tonight, according to weatherzone.com.au.
A pool of cold air in the upper atmosphere, currently situated near the South Australian/Victorian border, is expected to track across inland New South Wales today before reaching the ranges tonight.
This cold pool is likely to cause temperatures to drop further across the region, leading to the potential for snow to fall along the Southern and Central Tablelands, possibly even extending up to the Northern Tablelands.
"This week, we have seen some extremely low overnight and early morning temperatures over New South Wales, but these have been accompanied by clear skies, and dry air, so no snow has fallen," weatherzone.com.au meteorologist Matt Pearce said.
"Tonight, the cold pool of air will coincide with high levels of moisture, so we are looking at a good chance of snow falling on higher ground, possibly even including the upper Blue Mountains."
Meanwhile, a thick blanket of cloud is keeping daytime temperatures down today across the state. By 11:30am, the temperature in Sydney had only struggled to 10.5 degrees. As the cloud is not expected to break up this afternoon, the city will potentially be looking at a maximum below the forecast 15.
If the city does not exceed 13 degrees, it will be the coldest day in Sydney since 22nd August 2008, when the mercury struggled to just 11.9.
"The current spell of chilly weather will ease over the weekend as milder air spreads across southern Australia. However, we are still looking at temperatures hovering around the 17 or 18 mark right through next week," Pearce said.
