    Looks like some good rain for the East Coast of Tassie which relies on these sort of systems for decent rain.

    Yeah, just hope the centre of the broad complex low stays to your north for that onshore flow.

    Such a slow-moving stationary cutoff low is unusual. But delivered big time in early May.

    The snot at the back end of this is gonna fil the main range in nicely.

    BOM 4:20 update are hedging their bets between rain and snow. Perisher says just rain while Thredbo and Hotham say Snow. What is it guys?

    Snow or rain. Heavy falls possible

    So, why can’t BOM Vic do this for Victoria?

    What possibly could they not know in HQ Mel that allows it to be so in NSW? C’mon BOM!

    They just put it in the regional forecasts, as opposed the location forecasts.

    Fair enough but it’s not the same MC?
    One neat alpine chart with snow probabilities at 3 heights? Per day?

    yr.no updatre is still just the 6am update redone at 11:33am - should update to next new version in an hour or so.

    looks like a wet sheep dog that got lost from the west side of the hill. Porridge in June - how good is that!

    To be fair, on paper Buller and the Western Alpine actually looks not to bad on paper above 1700m for early Saturday.
    There's some intensity in those falls and although it doesn't leave Buller with a lot vertical snow gain these intense falls could put snot in village early IMO.

    EC Ensembles 24 hrs rainfall total to Sunday 10am Local.

    A good indicator is that the predom falls are on the Western/NW slopes of the Alps, indicative of low level moisture, which is typically (in Aus) not fit for DGZ/snowfall development.
    Still looking like a 5-10cm gain in the resorts (1700-1900m vert)

    Heaps hard to forecast.
    ACCESS eyeballing getting towards dump amounts.
    GFS and CMC with a reasonable mid-tier system for June.
    And EC lucky to have a dusting for Perisher.

    There’s been anecdotal evidence from some people within the forecasting community that ACCESS-G seems to have a general habit of overcooking precip. It also seems to be quite aggressive with some cutoffs.
    Will be interesting to see whether this will also be the case with this time... or whether this system will be an exception to that.

    We like personification of our weather models round here.
    AXSG is that drunk uncle mumbling angrily at the end of the table. However occasionally he finds a subject he knows about.

    Though his behavior has improved.

    I hope he's on the ball this time.

    Seems inline with EC & AXS-C (snow accumulation above 1900m, until late Saturday arvo, night IMO).

    Same with the rest of the ACCESS suite IMHO.
    It does best in the biggest systems, and overcooks what should be small top-ups at certain occasions.

    This Dump (Period) is a base filler. The next dump next week (14 Days) at 18Z Mon GFS looks like the mint for eary season pow.

    A tinge of purle showing for the main range Tuesday morning.

    Not just a tinge.
    You got a ~50-60cm dump.


    Now if that isn’t a base filler, I don’t know what is.

    The difference between that and CMC/EC is so polarising that it’s almost ridiculous. Almost.

    I am so confused by this, and enthralled, I'm up to Hotham end of next week for the weekend I'm just hoping this thing comes off and nukes the place...still sounds like it could go either way this close to the event too this is an absolute thriller!

    Of course it's also worth bearing in mind how wet or dry the falling snow will be depending on the lower atmospheric temp profile considering its big effect on snowfall accumulations on the particular model maps which use the assumed 10:1 standard snow to liquid ratio rather than model-derived ratios.

    I reckon above 1700/1800m will be good to go. But doesn’t leave a lot for Vic.

    Wet snow = build a base. I’d be happy with any snow.

    Hopefully a Perisher system. Looking at the satellite image, there’s a lot of something coming.

    Surprised that the BOM is yet to publish any warnings for NSW? Thought that there would have been at least a sheep graziers alert this close to tomorrow given the forecast. I guess it’s coming with their next update .

    Normally one would think a three headed low with embedded troughs is a recipe for a dump, but I'm no expert here.
