    The models are lined up for a significant cold outbreak starting from tomorrow Thursday August 20 into early next week. Weather patterns have reverted to a more normal August pattern, with the highs up North, deep low pressure to the South and strong W-SW winds over SE Australia including NSW and even Southern Queensland in between.

    A series of cold fronts will cross SE Australia in the next few days, bringing cold temperatures and rain to the Tablelands and slopes and snow to the Snowies, Southern and Central Tablelands, the Barrington Tops and the Southern parts of the Northern Tablelands. The first of these, an opener if you will, passed over Sydney late this afternoon after having brought soft hail to parts of the Central Tablelalnds.

    Here's the forecast synoptic from the NZ Met for 10:00 tomorrow (AEST):



    Meteye shows snow falling as early as tonight on the Oberon Plateau, with snowfalls likely on Friday and the weekend. The forecast for Oberon (1100 metres) has a snowflake icon against Friday, Saturday and Sunday - not often you see that. Snow is forecast to fall as low as 600 metres on Saturday 22nd, including Bathurst and Katoomba.

    Love your work Steve.
    Great thread start and I look forward to all the updates. Unfortunately, due to all the kids sport over the weekend, I can't do a road trip which I would have liked to do.
    I look forward to reading any reports.

    Thanks Steve, have followed your posts for quite a few years, Weatherzone Forum, quite the family, very happy ski.com adopted us to continue our interest in all things weather. Looking forward to this upcoming weather, something so very different to the last few years, seems like weather I remember from 'the old days' like the winds of August'.

    Yes it looks like an exciting blast of snow further north. Will make the mid July falls up into the tablelands look tiny if this comes off.

    Gotta love a speckle that's bigger than NSW, VIC, and SA combined. Looking forward to it covering all of SE Aus in the near future.

    Coldest air through BMs & OP (EC) pins it at between 14-17:00 hrs SAT where snow will fall above 600m IMO.
    At this timeframe, we'll see freeze levels around 1000m ASL. I am seeing 10-12cm accumulation above 1100m out of this, favouring the Western aspects of the GDR.

    GFS still indicating a little snow for us in Bowral (3cm), EC not interested. I'm heading with a few friends and the dogs in the AWD to Crookwell Saturday and will post pics.
    Any thoughts re snow in Bowral appreciated, although can't say I'm really expecting any.

    Lee wave cloud being generated east of GDR visible on latest 3 hour sat loop. Watch it move north up the coast to be now above Sydney.

    Mt Boyce at 4.6 degrees, so needs to drop at least 3 more. Cold airmasses hold less moisture so there won't be too much snow at this location. Still, pple get excited at 2 cm worth.

    Roads will be a mess tomorrow up that way. Lots of people heading up tonight and Channel 7 doing their usual media thing promoting "25cm possible in the BMs"...

    Really appreciate the work you lot do and I apologize if this isn't the spot to ask the question.
    My family an I have missed out on getting to the mountains this season but we were really hoping to see some snow fall over the weekend and were thinking Crookwell.

    what are our chances of seeing some flakes over Saturday/Sunday?
    The models looks positive in my eyes but I know little in this game.

    Likely to see some possible accumulation in Crookwell throughout tomorrow. Should be all over by Saturday night IMO.
    I wouldn’t expect there to be much evidence (or falls) or snow in Crookwell by Sunday IMO.

    Thanks POW, appreciate it.
    Would you have any tips on the best locations to see such a thing withing a 4hr radius of Sydney town?

    Rain has just stopped here in Bowral. 2.9C now and some moisture building to the west looking at the radar. Fingers crossed we see a few flakes!

    Drive to Hampton and then take the road up to Mt Bindo. Take care though if you have only 2WD as it could be slippery. Should be snow near the summit if not below. If it’s not there then go on to Oberon/Shooters Hill. Good luck!

    Yes...we are cut off from the East for now by road. A light cover here too in Orange. Snowing lightly again now. Channel 7 just had a live broadcast from Robertson Park in Orange’s CBD... I’m glad there was at least a little snow for the viewers to see.

    Just arrived in Crookwell and its a sunny 2C. Went through some sleet on the way up from Goulburn and a small amount settled just outside Crookwell at around 940M . From looking at the clouds, at the moment it looks like it will come in short burst.

    Thank you all for the reports and pictures. Nice video of snow in Mt Victoria.

    It’s sunny and windy but not particularly cold in Sydney, with the occasional passing cloud. The radar shows showers reaching the coast at Newcastle, although just 0.4 mm so far. The temperature dropped over 5° (from 13.9° to 8.5°) in under half an hour. This didn’t happen at nearby sites. Malfunction?

    EDIT: now Williamtown has dropped by 3° to 10.9° so it’s real.
    I note that there's precipitation at Mt Boyce at close to 0° so it must be snowing there.

    Yep can confirm. Interestingly we drove down to Govetts Leap about 1km towards the east end of town, the rain shadow effect was noticeable compared to the west side, no settled snow and less precip.

    Yeah. We live about halfway between the town and Govetts Leap- we get nice falls but up at, say, the oval, there’s always noticeably more.

    Light falls here at the moment.

    Radar looks like plenty more to come down south on the OP around Oberon and Shooters hill. Mt Trickett will be doing well in this setup I reckon. I've snowboarded down the road out there at 1am in my younger stupider days LOL

    One of my mates drove up the hill this morning, and whilst there's been some nice falls in the BM's there is also bulk punters. Unfortunately I'm stuck at home with a sick 5y.o and reckon it's going to be chaos by this afternoon. If the snow level really does drop to 6-700m tonight I might go for a cruise to have a look. Snow down to Hazelbrook would be pretty impressive
