The best you can do in Australia.

Still no guarantees, but I am kind of resigning myself to the idea that it will probably get above freezing for a while, thus leading toward a period of low quality snow or a changeover to rain. But a weaker surface low would help toward minimizing the duration of above freezing temps and how far above freezing it goes.

And the top of the ski area only gets 60-70" of snow annually?

Right..if extrapolated I assume would come south but also weaker

Not that it's something to take to the bank given it's the 84 hr NAM, but the surface low is way weaker than the 18z Euro was at 90 hrs.
