Small flurries of snow flirted with snow chasers on Monday, but the Bureau of Meteorology predicts Wednesday holds the best chance for a dusting of powder at Barrington Tops.
A warmer winter season has meant cold fronts have struggled to push their way further to the north, lessening the chances of snow at the World Heritage-listed rainforest.
Bureau meteorologist Helen Reid said Monday's flurries are hopefully just a teaser for what could come later in the week.
"We just need the timing of the colder air at the same time as there's some rainfall, so it all just needs to line up," Ms Reid said.
"We often get a cold, dry air through this part of the world, but to have some moisture associated with that is less common."
Ms Reid said a "light dusting" is probably more likely for Wednesday, but "who knows?"
"Wouldn't it be delightful if it all just cooled down that bit more and we actually get a nice little white blanket," she said.
"We haven't had much in the way of cold outbreaks this season, and so it is just exciting to consider that on Wednesday we might get a little bit of a flurry of snow."
Warm conditions and a stable ridge of high pressure has stopped most cold fronts heading further north this season, which means areas like the Northern Tablelands, Armidale, Tenterfield over to Queensland and Stanthorpe have also missed out on their usual dusting of snow.
Ms Reid said October could bring colder weather and with it some snow.
The temperature at Barrington Tops is expected to drop to 2 degrees overnight on Tuesday into the morning on Wednesday and hit a high of 7 degrees in the daytime.
If there is any snow, Ms Reid predicts it will be quite early in the morning, with clearer skies heading into Thursday.
