    Think you are short-changing yourself. Think myself this low maybe a loose cannon.

    Gut feel.. This low is 1400-1600m porridge.
    Though the rates around the midnight to dawn period are encouraging for lower numbers..
    However the tail is warm.

    Unless you are Canadian
    And I'm warming to them.
    There is some logical consistent progression.
    And I'll be brutally honest. They picked it last system

    The 12zEC ens master was still holding serve. loose cannon. Deterministic mslp run away from its own ens.

    I kind of get more turned on by the 138 hrs & GFS. Better winds for swell generation and snot.

    ICON and CMC are sitting on the fence as the Canadian and German does not have an independent mind to pick through the ensembles, they leave that to the Yank.

    18Z precip wet one forecast for the eastern seaboard. What you would expect with a forecasted low in the region.

    Still a decent spread with where it will be and drift to off the coast. It's really more about what this feature will do to the coastline. And the possible flooding in some area's that may come with it. I leave it @that now and just watch. Likely a rough ride for some.

    Can I just say, that so many of the charts in here are out the date range. It's making it very difficult for the lay person, to understand what is actually happening on the 24th and 25th of July. <Relayed to me by a confused fellow forum member>

    Yeah, the time window has grown over the last week as multiple systems seem to be somewhat intertwining, it believe we are now looking from the 25th through to the about the 29th as 2 events flow through.

    Can I, as a simple befuddled lay person who likes gaining weather/snow info from these threads, make a suggestion to all you learned weather folk? While your charts and interpretations of the models are very much appreciated, you may as well be talking Swahili unless you add a very short and simple analysis for the amateurs such as me (eg "snow to 1400m", or "sucks big time - bring your raincoat" etc) - so far I'm getting the sense that there's nothing in this system snow-wise for the Snowy Mountains.

    Haha I don't mind it, I'm not a meteorologist but I can pick out the main points from the comments and that's good enough for me. If you other laypeople can find a good weather school where we can all learn more stuff from the basics through to more advanced stuff I'll join in! (not sure this is the place for that though)

    My posts are not important they are what i see and think they are showing in the models to me. People Interpret them differently. I see a extremely low confidence forecast for snow @ that date 24-25 atm.

    Your best bet is the official bom forecast.

    Date range extended.

    For those who need a recap:
    The initial UL low on the 25th dissects the SE and winds up as a Tasman Low.
    This system is then reinforced with an upper level trough on the 27th, which deepens and broadens the Low in the Tasman.
    The outlook for snow in this date range is limited and reliant on the position of the Low.

    IMO, at this stage both systems fail to position and influence the Alpine region with any snowfall, as it currently stands.

    About as close as GFS gets to snow influence on this date range.
    00z (the latest) run, which would be bugger-all, still quite fluid however:

    No need to go to the BOM Lady P. All your weather needs will be serviced here. :)

    So here's BOM and Weatherzone for Perisher for the date range.

    As you can see, it's borderline whether it will fall as snow or rain. I'm thinking, with the elevation of Perisher, it will be more of that glug we got last week. But it could go either way. Not the best snow for skiing. But good for future trips. IMO of course.

    BoM has the low further north than the last ECL. @Astro66 please note that you need to look at the chart with 'Friday', 'Saturday' and 'Sunday' as being in the thread date range. Thursday is unfortunately outside the date range, but that is how the BoM supplies the chart.

    Thanks @stormkite2000 . Your posts are important; I noticed that BOM weren't terribly accurate with their forecasts last year so it's always good to have an analysis of the various models here in this forum (which has proven invaluable in the past). Just a few words to go with the charts ....

    The uppers will be cold and its likely to be lingering.Any moisture will likely be falling as flakes in alp regions

    Looking like a wet day at Pfv level tomorrow. But Monday looks ok for a rare "snowy day" in 2020

    What's the prognosis for tomorrow at Perisher? Is it still a snowy day?

    Looks like solid amounts of rain to me, tomorrow IMO.
    The upper level warm-air advection kills it.
    A sloppy snowfall gain above ~1750m, I'd say. It may fluctuate to wintery mix throughout the day with strong adiabatic influence.

    above 1700m it should be wet snow - says the BOM - might be wishful thinking though - sure looks like a quality rain event sitting in the balance. but the forecasts all seem to say we'll dodge the pineapple.
