EXPLAINED: Why it will snow on Southern Downs tonight
IT takes more than negative temperatures and a lot of wishing to make it snow this far north.
According to Bureau of Meteorology forecaster Dean Narramore, it's a precise combination of atmospheric temperature and moisture levels that bring about snow.
"We need a combination of very cold air at the surface and through the depths of the atmosphere," Mr Narramore.
"We also need moisture, that means clouds and showers at the same time the cold air comes through."
HOW TO GET TO SOUTHERN DOWNS SNOW HOTSPOTS
Mr Narramore said it's rare for Queensland to see both variables combine.
"Normally, we get those really cold morning, but it's very dry," he said.
"It might be -5, but there's no moisture in the atmosphere."
Mr Narramore said last year's snow was an incredible stoke of lucky, with a freezing atmosphere combining with "a lot of moisture" to produce thick blankets of snow.
It's likely we'll get the minus atmosphere temperatures, but whether the moisture levels are strong enough for snow, we'll have to wait till tomorrow to find out.
