    It's a late bloomer. EC showing it stronger on today's 00z run.
    Maybe a 5-10cm, with some a bit of wet stuff ahead of it IMO

    It actually looks like it has a very cold backend. Perhaps ~500m snow levels in Victoria IMO. Important to help cement the base back down for a while, and prolong the corn harvest.

    Certainly looks cold on this run (Hotham 1650m). If the temps stay there and the moisture bumps up a touch towards the end threre will be some nice dry freshies to be had...

    Zooing Out, waiting for EC to run this again.

    Ec looking much better than GFS. Its kind of modelling a return of negative SAM.

    12Z run puts more cold air into the mix. EC a little colder than GFS. Even the Canuck is into it!
    Problem is cold air is looking somewhat dry and the ridge is ushering it through quite quickly.
    5-10cm for Southern resorts IMO.
    Looking better than last Friday’s mess though.

    EC


    GFS

    GFS posting some viciously cold temps over southern Tas on Saturday arvo.
    Snow to a coupla hundred metres above sea level, on paper. Coupled instability it's gonna be interesting Saturday arvo in the Apple Isle.

    The progression is developing each model run @ GFS.

    [​IMG]

    Although still a bit stronger front on EC.

    [​IMG]

    Zooming out EC has 3 or 4 Nodes in the LWT.

    Does the AAO in positive phase partly spin up the various nodes forming around the pole, and then as the phase moves to negative they are unleashed into the Southern Ocean?

    Will be interesting to see the long range forecasts for the final weeks as come into view. Sure looks like we will get a final burst of minty.

    Saturday drive down looking better all the time for this coming weekend. Sunday and Monday look to deliver one more burst of winter fun.

    Like the look of this one for southern and mountain vic.
    The purple line pushes up really high and then looks to leave 528 thickness through south vic on sat!
    IMO
    Chance of a flurry through the higher strezleckis I reckon ❄️

    Yeah I can concur with this opinion. Last week of Sept and first week of Oct could feature a bit of a last hoot.

    Latest EC looks like 500-600m for Southern VIC, maybe isolated falls down to 400m.

    Snow to 200m for west and south tassey and 300m for north west tassey! That’s cold!
    Thinking southern vic could see possibly that 4-500m snow level imo

    Interesting to see BoM go all-in yesterday PM (8-20mm for Saturday) then scale it right-back this eve (1-5mm), back to near where they were yesterday AM. A sign of low confidence IMO.

    TBH can't see where it's derived. Every model I've looked atfor the last 3 days has 5-10mm for Perisher/Thredbo.

    Yes. No. Kinda.
    A strong positive AAO phase means contracted, yet strengthened cicumpolar (Westerly) winds. Put a 'strong phase' in Spring after the perpetuation of a strong negative phase and it often means an increase in up-welling of warm circumpolar currents (the presence of +ve SSTAs).
    +ve SSTAs are a good place to start for convection and generally more precip/humidity but as AAO variability is largely driven by the Polar Vortex & ENSO it doesn't directly correlate to a swing back to negative at this time of year.

    IMO 5mm rain followed by 5cm snow - or something in-between depending on elevation ...

    Quite a big system.

    20 cm is quite possible in some places IMO. Windy but.

    Cold, yes, but I suspect it dries off quick, and perhaps most of the moisture is on the change.

    Something like this. Not much in it, as @Claude Cat said above.
    Snow in very weird places, could be interesting. Grampians, Ballarat, Otway, Strzeleckis. Maybe something for SA around Mt Gambier?

    IMO looks impressive but the reality is that it's too cold for a big dump but it will be nice for a spring slide if you can hide from the wind

    Strong lifting for the initial onset, with ideal vapour transfer at the 700hPa level- but available moisture/ mixing ratios take a dive soon therafter . GFS various parameter overview would have me guessing more than EC- perhaps 10- 15 cm.
