    I like the 2nd part better as its a larger cold pool. This first cold break looks to be localized, but may deliver up high.

    EC Cold pool → (Ull-vort) wedging in on the western edge of the front over VIC and dump. Then likely drop ↴S and bomb off NE tassie. :)

    GFS has really left the 9th. But its fluctuating a lot between runs so may come back.

    GFS also came up with something unusual for the 13th, which I would froth on if it came off.

    Yeah, GFS00Z has the uppers as still pretty cold for late on the 9th. Still fear they'll arrive after the fact (rain).

    Sheesh, she's frigid. Canadian certainly has the colder air more aligned with some moisture.

    I wonder if it has a lot to do with geo-potential height calibration?

    These are calibrated and adjusted in the models on a seasonal basis. Just wondering if any one can confirm here.

    But yeah i like the vorticity chart, should get things happening enough to get snow.

    The front does look wicked west of WA.

    So I'm a bit thrown by the models today. Downgrades this morning but everyone still seems bullish tonight. What's the concensus?

    Friday's still there but low confidence in it doing much good - there will be lots of rain followed by cool drying air IMO. Some good mechanics progged but not all the ducks are in a row to deliver anything substantial, that's how I feel about it. I think Verm put it well this morning, models are a bit hot/cold on it so it's too dicey to call.

    Sunday night through Tuesday looks like our best bet for cold air and top-up showers. Still got 15-20 cents here, I think.

    Those shots are awesome. You can make out the flooding on the Bogan River and Macquarie RIver. And the coutryside looks awesome.

    That's bold of BOM given it's +160hrs out. Modeled off AXS, which I kinda feel is a couple of steps behind the other models at the moment. This is looking more and more less likely IMO.

    A September to Remember? Perhaps not just yet, but EC is mostly on board.

    As for this week here, going to be flooding in the local rivers I suspect with a strong likelihood of 50mm+ rains....

    IMO this is just looking like a rain event on Friday and Saturday. Perhaps a little snow about 1900m later.
    But the 12th & 13th is looking a lot stronger IMO and is quite promising as snow event.

    Jane's forecast is inline with what you think CC.:)
    http://www.janebunn.net/snow-forecast/

    I'am sticking staunch with snow over the ranges late on the 9th early into the10th am,live vapor-satellite and 700mb cold injection progs are suggestive to me there will be frontogenesis .

    Hence the eyes on the vorticity plots. I see where you're going here. I am eager to see if it pans out.

    As much as this rain will stuff my work up friday, I like it.
    Thank goodness the last few 'dry' years in Victoria were nothing like 06-late 09.
    Love a wet spring and weekly/fortnightly summer rain events here in Victoria. Hope we get them.

    I'm with Jeffx on this one.
    Possible earlier change to snow above, say 1650m.
    A chance.

    Looking good Monday through Wednesday. With an upgrade on both models this morning IMO, with the deepening of a Tasman low off deep South Coast NSW. If that positioning verifies (and stalls as models suggest) we're in for some big totals.

    The transition in 2010-2011 was similar to this, so hopefully we get that again this year. People with more brains than me seem to think we will.

    It looks good, but after a big rain event I am always a little skeptical about the snow level from the next front. I feel it's usually a little higher than you think due to lingering moisture.
