    No, it's certainly possible. I just don't like betting the house on a cold pool and where it might go! :)

    Does ACCESS-R stand for ACCESS-Rain ?

    Line ball but it looks okay with respect to shape. Just needs the uppers to find there marbles. Clears nicely on Monday.

    Need to book in another main range BC trip.

    Perhaps I was being a little flippant, and didn't make my point clear

    I am talking about Perisher, because that is what I follow. I understand they use EC. The modelling got the general trends correct, ie predicting fronts etc. However, there is no doubt in my mind that the computerised predictions for perisher, which use the EC data, this year have had problems with the callibration. Their models have consistently predicted temperatures 1-2 colder than other models, which often has resulted in predictions of snow when it seemed improbable and more likely to be rain. Others on the forum have commented on the same thing this year. Not sure why that is the case, but it has been quite a consistent trend.

    As I said, I only follow perisher, so I don't know if this is just perisher, or a problem with other oz resorts as well.

    YR has several "Perisher" forecast points:
    Village at 1719m
    Mt Perisher 1930m
    Back Perisher 2000m
    I'm not sure which one you're using, but I'd expect the Village would be more representative of the resort as a whole.
    Certainly it can show negative temperature values for Mt Perisher/Back Perisher where it's zero or +ve at the village.

    I really don't see much chance of snow until Saturday afternoon / evening. IMO

    I generally look at the village level for Perisher but don't think the snow icon is very accurate till the temps shown with it are at -2c and below.

    So this all looks very marginal IMO. May get some love above 1800m from saturday morning so Mt P could do all right and help kick Eyre T bar area later into spring. IMO

    As Danny Archer said, the "Vibe left this place long ago" haha

    But it will be back! All swings and roundabouts in this thing we call weather.

    Sat Pic indicates that the Low has some cooler temps (spinning over Western SA) but I cant see the cold core lasting long enough to reach the Alps. Especially with the Pineapple Trough leading it.

    Have to agree. Mt P should do ok later tomorrow and hold on into mid Sept.

    Consensus with the GFS on the pool. Appears small on the plots,but as the crow flies its a large circumference.

    How much moisture is left by this stage? This looks very late Saturday to Sunday morning. Looks pretty dry to me IMO

    The cut off vort looks loaded with moisture CC on the plot, air sounding samples @the 2nd-3rd will give a more information.

    EC has 40 knot southerlies and 2C @850mb. Uppers 'aint fantastic but IMO we'll see snow in the resorts before it completely dries out around midday. If that happens 10-15cm in the resorts, if not ~5cm Saturday night/Sunday morning.

    jeffx, you know that I love your work but chasing the wandering cold is fraught with disappointment.

    Yes, it delivers when it hits but 1 in 13 bro.

    The devils elixir!

    What I like about the polar view is the lack of blocking/strengthening high in the Indian Ocean, what I am not so keen about is the significant warming of inland WA/sustenance of the inland Highs over central Aus. Hello spring.

    @The Fallen, thankyou and yeah true. i also like the trends with the steady lowering of the temps.

    @POW_hungry, Yeah that broad scale change has been showing on models now for a few weeks,the Indian monsoon
    is also retreating earlier than usual. Could be a early start wet season over the top-end this year.

    Can confirm It's been snowing at Hotham for about an hour. Pretty heavy with big flakes but only sticking to metal. Still a bit damp for anything else
