Australia’s eastern states are facing a gloomy end to the week, with a sweeping cold front forecast to bring “heavy falls” and cool temperatures.

Wet and windy conditions have lashed parts of South Australia, Tasmania and Victoria over the past few days, with New South Wales and parts of Queensland now in the firing line.

Sky News Weather Meteorologist Marina Neuman explained “unseasonably high” rain totals across the interior of SA looked set to continue, while widespread falls were forecast along parts of the east coast on Friday morning.

“Rainfall will continue for many,” she said.

“We’re seeing the potential for some high totals as well, just in the next coming hours, especially for Queensland, as well as across the alpines.

“Starting to see the better chance for rainfall across the eastern coastline, there’s heavy falls across Dubbo, as well as Orange.”

Colder temperatures are also in store for many areas as the front pushes through on Friday, with cool conditions forecast to stretch into the weekend.

SA locals should at least get a slight reprieve on Saturday, though, as a high pressure system slowly brings warmer and direr weather to the state.

The cold front’s arrival could spell disaster for skiers, potentially washing away much of the early season snow.

“We could be seeing totals from Thursday (to Friday) reaching at least 50 millimetres in the alpines just in that 24 hour period, which, despite the drop in temperature, could bring severe impacts to those snowfields,” Neuman explained.

“We’re unfortunately looking at the potential for all our accumulated snowfall, early on into the season, to really be washed away.”

Neuman added there was “a chance for some additional snowfall in the forecast”, but it would likely be limited to a few centimetres across the highest peaks.
