    So how's winter going to unravel this year?
    El Niño?
    Lake Eyre? The birds that go to it?
    Some awesome algorithm made by a certain Brisbane hydrologist?

    We don't exactly at the moment. So guessing time!

    CFS is currently forecasting a higher pressure anomaly in June, improving over winter to a weak month average low pressure anomaly. And Spring looks good with some strong lower pressure anomalies in the monthly average. These are the corresponding 500hPa height anomalies from CFS.

    Late winter? Well CanSIPS and NMME are forecasting differently, so don't hold your breath for an accurate answer. One thing's for sure, it will be interesting.

    I predict winter...............
    will arrive
    there will be the constant battle of high v low , high will win some and low will win some
    some will acclaim a certain hydrologist from Brisbane to be the new messiah
    others will scorn that same hydrologist
    we will have snow in the hills and people will be happy
    people will whine that there isn't enough snow
    the lifts will open and there will be crowds on weekends
    people will whine about the crowds on weekends
    there will be the gnashing of teeth when windhold events happen
    there will be those that whine just because they can
    these and a million other things will come to pass

    but winter will arrive and I for one will be damned happy when it does :):):):):):):):)

    Not really into weather charts and studying patterns or data. I normally go off gut feel, or walking around the back yard in my undies as a gadge. Going off what I'm feeling right now, I predict a 3metre plus reading at Spencer's Creek in the first week of August.

    EC This is just a look @ the pattern EPS is suggesting over next month,
    basically a train of fronts/ with cut offs slamming VIC.

    Fellow interested skiers / boarders, alpine aficionados ...... and weather gurus (I definitely do not fall into the latter category). When it is all said and done, do you folk look back and extrapolate the predictions against the actuals? Any history on say the snow predictions or weather forecasts against what you felt would happen? No challenge on my part, I'm genuinely interested to understand this stuff. Cheers

    FHS ... as it sure looks dog at the moment. Need a good May/June ahead of an elnino should it appear in mid winter.

    for what it's worth - i'm leaning towards a 2014 year. stunning to start with before going to the dogs in August.

    I look back on my seasonal predictions and my long term forecasts as a whole(on my blog in the bio). I write the reasoning for my forecasts down, and once the season is done, find what went wrong. I find the errors and problems and make solutions for them. And then I put those into practice. Nobody can write the perfect forecast, but small steps to make them better will help a lot.

    As far as Australian snow forecasters go, The Frog and Grasshopper make no effort to review their mistakes in their forecasts from the public side of things. Gerg and I think that Mr Peterson guy review their predictions vs observations. People here and on other sites have found the flaws to my long term forecasts and I definitely take them on board. Opensnow, a big American snow forecaster, openly reviews their seasonal forecasts and others too, which I think is very good and gives me more respect for them.

    I think Gerg has a graph of his model's predictions vs observations. I can't speak for the other guys on this site, but there's my 2 cents. Great question btw!

    P.S.
    And I also review my personal decisions on a monthly basis. If you don't review and reflect on your mistakes, there is no hope of your life getting any better except by random luck.

    Jellybeans - Nice reply... please know that I was not questioning anyones insights or expertise.... As a novice on the deeper insights regarding weather forecasting beyond what I see on the weather channel or from my window, was just interested on the science of forecasting compared to actual events over time. Hope that makes sense? Keep those forecasts coming..its interesting...! Cheers

    What does that religious fraudster say? (Forgotten his name - the one who has babble verses posted all over his forecasts.)
    Well, really, we don't need to know what he said about this winter. Every winter according to him, will be the best ever.

    My punt = Lots of early frost/ ground cooling. 1 pineapple in June, none in July, 2 in later part of August and a painfully dry September. Tropopause will be gracious to us in July.

    OK then...

    Buller will be first to open 27-28May after running their containerized snowmaker day and night.

    Perisher will open on the QBW after running snowmaking on the front valley.

    There will be a good dump of snow during the first half of July which will allow the other resorts to open with the assistance of further snow making.

    The next decent dump of snow will occur in August.

    It will be rainy and windy during inter-schools.

    Several decent snow events will happen in August-September and max snow depth of 188cm will occur at Spencers Creek on Sep 21.

    Cold fronts in September-October will bring rain followed by snow top ups that don't replace what was washed away.

    Normo will ski past the 1 million vm mark after telling everyone he is just aiming to ski every day and he isn't worried about vms.

    Most resort areas will be closed by the October long weekend. Perisher just scrapes through to the long weekend.

    The backcountry guys break out their AT/tele gear and ski until the end of November.

    so better than a crap season. it's generally a 1:3 chance for a fizzer season - 1:3 for average - 1:3 for epic.

    which reduces to 2:3 for good enough.

    He's predicting a great crappy season which we all know and love.

    There will be pow days but you gotta storm chase, ski the worst of the weather and poor viz days to get the biccies.
    Pray for wind hold on the chairs (and the ropes to go out at Blue Cow) and then go play in the trees.
    Look at the spaces not the places.
    p.s don't complain about the rocks they where there first .
    It's a good day if you don't hit any. ;)

    If not much change's over the two months i see a good season ahead.
    It may only take one good tasman low to break records and it due this

    Doesn't matter if 2m falls in June , 3m in July , 2m in August and a top up metre falls in September - there will still be those people who will say we didn't get enough and it was only an average season in their view.
    What will happen will happen when it happens and we should all be happy that it damned well happened at all. For me .............I don't really care how deep it is as long as I can ski on it when I want to ski on it ( late June to mid August).

    As for a prediction over and above my earlier prediction.........................peak depth ( which really doesn't mean a great deal to me) of somewhere between 175cm and 195cm which should be plenty for everyone but it wont be..........you can take that to the bank.

    SMSkier - I make my living from the dirt I own near Tumbarumba so yeah I am constantly quantifying actual against forecast , if I didn't I would go bankrupt pretty quickly.........do I post my good/bad results on here.........not very often although I don't mind admitting I got it wrong but my real concern is why I had a good/bad result.

    Let's get this straight once and for all. I never contested the credibility of anyone! I simply asked Jellybeans an innocent question to which he responded (and to which I thanked him). Simple as that. I never mentioned specific snow depths etc. I queried about predictions and actuals in the context of the weather forum! For reference, my farm is in the rain shadow of the main range and depends on decent rainfall. It can piss down in Jindy and we miss it - 3mm in this current rain event. Same as many others! In respect to the snow depth, I ski locally probably as much as many folks on the various forums and to your point, the depth is irrelevant if there is sufficient cover. All the best.

    Apologies from me too, I left out something very important from my season prediction post.

    At some stage this year I will infuriate a certain felis catus and be told off in the weather forum (again).

    SMSkier , I didn't think you were contesting anyone's forecasting credibility , far from it as I read your post. As far as snowcasting............my credibility isn't outstanding and I certainly don't hold myself up as a guru , more an interested observer , interested mostly because of precip/frost events that are part and parcel of winter that do affect my livelihood. I only threw in my snow totals as an aside and if you look at them probably 80% of seasons fit that range anyway.
    I am sorry you missed the rain over the past 36 hours , we on the western side of the range got significant totals ( mine was 63mm) which was the first real rain since mid November.

    Latest SOI is showing faily typical collapse back into neutral zone - the atmospheric condition would seem to preclude an El Nino actually developing this year.

    This could go similar to 2014 - with BOM the first one to give up once the early Austral Autumn data started to get worked into the models.

    Long Paddock shows where SOI is going:
    https://www.longpaddock.qld.gov.au/seasonalclimateoutlook/southernoscillationindex/30daysoivalues/

    And look at the 90 day numbers - flat all the way through. Only the 30 day SOI has given weight to an El Nino.

    Next ENSO update on Mar 28th might see the first downgrade by BOM.

    Tough to predict in my book. We can go from a little snow coming to suddenly a change in conditions and it turns out to be 30cm. Wait and see.
