    Given the current EC and GFS runs this system could be very deadly for Gippsland... never mind the snow, I'm seeing some serious flooding potential here. Many parts of the region are already mud.

    Good point ice_man. 9am GFS centres the moisture more over the alps rather than over Gippsland. I'm still thinking 50-75mm is possible, especially with that SE aspect.
    I'm trying to recall, didn't we have a similar system in early June a few years back (IIRC falls of 150mm in Gippsland)? There was severe flooding then. 2007 I think.

    I think some sneaky snow for Victoria wednesday night into thursday is on the cards...
    Off the latest AXS-R charts
    the cold air has penetrated much further than on GFS

    22cms at top of Thredbo....as a prediction because this is what the thread is called. There is divergence as seen here and there amongst the various journeys into weather prediction for our snowy time of the year - on average. I would call this one a little ambivolent for a system where it could skirt.......hmmm, or dump.

    IMO the system looks better on GFS this afternoon. Freeze level perhaps 1400m.

    Re: Predictions: May 23rd - 27th

    Snow-forecast now have a total of 1cm for this system. How on earth do they go from 11cms in the morning to 1cm now. I suggest they are just a little wired.... and I ask how good are all these computer models if forecasting is so all over the place and often incorrect. I'll stick with more than snow-forecast!

    yr.no confirms the above update 20cm for Hotham and 25cm for Thredbo.

    Re: Predictions: May 23rd - 27th

    It looks as if as the inland low deepens and drops thru NSW, it will be fed some nice southerlies from the traling high. IMO, if the cold ppol associated with the low hangs tough and gets some help from a new injection of coldish air from the south, well geez, we all know what happens with deep lows, solid moisture and cold air.....Friday could be the bomb. Mid week next week could be interesting going of weather channel's (BOM) progged temps and precip.....

    Re: Predictions: May 23rd - 27th

    Pretty much everything is predicting a cold ending to the system IMO, so unless the snow is washed away literally as it falls, it should stay around as it freezes solid under the big high that follows. Hopefully there is enough of it to make it season opening though.

    Re: Predictions: May 23rd - 27th

    Today's progression of sat loops has shown a LOT of promise with the incoming fronts from the Southern Ocean. I've noticed over the years that the first in a series of fronts always dips away (heads SE) the second generally gets more penetration in to the Alps areas and the 3rd (and subsequent, if we're lucky) fronts smack right in to the Alps.

    Tonights sat loop (11pm) appears promising; the synoptic chart is damn near perfect, with a strong 1030 H cell well west of WA but shaped as a slanted ellipse rather than last year's bl00dy flat, heavily ridging types...and on the ABC weather tonight, mention was made of a trough currently developing over central NSW which is timed to meet up with the incoming southern front.

    So we have cold and moisture present, with the timing and alignment of the key players at this stage looking to meet.

    But there is always the development of a H at the last minute to truly fark things up, as we have all seen many times.

    If the current models are correct and the NSW BOM predicting likewise (for late this week), then surely we have to be looking at 15cm minimum out of this system?

    I'm going for 15-20cm by Sunday night. IMO.

    Concur Donza.
    EC has held firm (only the amount of precipitation has varied) while GFS can't make it's mind up. IMO shaping up as a 1600m+ system.

    Re: Predictions: May 23rd - 27th

    I'd agree with that. I reckon rain on Fri/Sat for Victoria, with snow on Sunday/Monday.

    NSW may get away with it and get more white stuff than wet stuff.

    Jane says hello
    FRIDAY and SATURDAY

    Freezing level lowering to about 1500 metres on Friday morning, then 1200 metres overnight. Rising to 1600 metres on Saturday afternoon.

    Snow, heavy at times, with 30 to 50 cm possible.

    Breaking to snow showers on Saturday afternoon.

    IMO going on the 9am GFS run, early Saturday isn't looking too bad.

    I'm not so convinced of the deluge on Friday (although it will be somewhat wet)

    Tails of lows that flip under and then back up are associated with high rainfall and higher temps.

    Projections are also for a contraction of cold air to the south over the weekend. Double Whammy.

    Re: Predictions: May 23rd - 27th

    Perhaps.
    IMO slightly cooler, but the bulk of the moisture now passing through bass strait.
    GFS still too variable for my liking to get a good feel for it.

    And so it begins.

    The weather nerds elsewhere are getting quite excited about this one. I suspect it will not be boring.

    IMO EC remains consistent.
    yr.no interpolates as 25cm10cm for Thredbo and 30cm10cm for Hotham. Potentially more at Buller if it's cold enough.

    Fark. I'm supposed to be working outdoors in Perisher all day Friday.

    Still could go either way at the moment (ie. rain/snow) but looking colder at the tail. Will pack the skis just in case.

    Saw a certain "expert" in another forum saying this could be one of the biggest events in half a century.
    Whilst i dont quite see that happening as you said claude its going to be an interesting event.
    One things is for sure, somewhere is going to get alot of rain, and its gonna be windy as hell

    Re: Predictions: May 23rd - 27th

    Where that bombing low develops will be the key to it. Understandably, the models are all a little different, we may well be guessing until we see the satellite pictures to confirm exactly what's going on.

    As someone pointed out earlier, looks a lot like a number of events from last year that left everyone frustrated. I don't read the models as well as many here, but 'the vibe' doesn't look good to me - too much north in it to start with, too much east in it to finish with.

    Re: Predictions: May 23rd - 27th

    IMO too warm for Baw Baw. I suspect this is a 1600m or above system.
    Potential to be very wet.
    Perhaps a little snow at the tail of the system.
