Australian Forecast – A Couple More Top-Ups Coming Up
Published early Wednesday, 17th September 2025
Yesterday, Tuesday, was not a great day. Along with strong winds, we copped a heap of rain, a whole 90mm of it at Perisher Valley’s weather station. The front has now pushed through, and colder air has arrived with about 5cm of fresh snowfall on Perisher’s snow stake at the time of writing. Reggae and the crew will have all the details in their morning reports, so check them out.
The snow showers will clear up this morning (Wednesday) as high pressure moves in for a mint day on Thursday. It’ll turn wet and windy again on Friday before the next front brings another cold change that night, and 5-15cm of refills throughout Saturday. Snow showers will turn wet down low on Sunday as temperatures and snow levels climb ahead of another cold change and fresh snowfall arriving that night.
Wednesday 17th September
Snow showers clear in the morning, leaving partly cloudy skies. Strong west-to-northwest winds gradually abate.
Thursday 18th September
Sunny, apart from a bit of cloud in Victoria, along with northwest winds.
Friday 19th September
A front spreads showers eastwards over Victoria during the morning and New South Wales in the afternoon while northwest winds strengthen, reaching gale force in exposed areas. There’ll be heavier rain at night with possible thunderstorms before a strong, cold westerly change turns it to snow overnight.
Saturday 20th September
Fresh powder refills throughout the day as snow showers continue to fall to low levels. About 5-15cm is expected. Strong, cold westerly winds gradually abate.
Sunday 21st September
Snow showers turn wet at low and mid elevations as snow levels gradually climb throughout the day. There’ll be heavier widespread rain and high-level snow at night as the next front hits. Westerly winds turn northwest.
Extended Forecast
The front that hits Sunday night will bring about a cold change and a top-up of snow on Monday, September 22nd. Another storm system is possible during the latter part of next week, but it’s still too early to make any big snow calls as models aren’t well aligned.
That’s all from me today, folks. I’m sending out these forecasts every Monday, Wednesday and Friday throughout the season. Have a great couple of days, and I’ll see you back here on Friday.
