Well, another could-have-been CT snow event concludes. This one became half-hearted overnight Friday/Saturday when low-level milder air from the Tasman Sea began circulating around the low near eastern VIC, fragmenting 850 temperatures that were already just a bit below borderline. Up to that time, there had been a good southerly infeed of cold air at all levels up to 300hPa from as far south as 50S.
An interesting aspect of the event, however, was how widespread the snow was given the very low temperatures above. The previous weekend's similar upper temperatures had only produced isolated hail and snow dumps from instability. Snow (falling or settling) was reported in this thread from Katoomba, Blackheath, Lithgow, Yetholme, Oberon, Oberon Plateau and Millthorpe.
A miserable day in Millthorpe today, with the temperature just barely reaching 4C, low cloud base dropping a fine drizzle and brisk winds all day. Home-made vege soup and roast tonight!

I am getting some snow flakes falling now at 1.6deg. These sort of deep southerlies use to drop dustings of snow here with very low cloud development many years ago, often at temperatures of -1 to -2, but I have doubts it can happen anymore.

Wayne, the road is closed in winter. You can usually drive though to Picadilly Circus at around 1300m and its a long walk from there. Corin Forest is a good drive, nice walk to Square Rock (6km return) at elevation 1400m from there.

I'm also looking at the reasonable thicknesses on the BoM 3 day model for the Highlands (around 538) with showers on Thursday and wondering if Robertson might get some sleet?

Just to get off Tablelands snow for a sec, could you southerners tell me how accessible Mt Ginini is? It's not accessible at all, really. It's deep in Namadgi National Park. You can't get there at all from the Cotter Road (unless you count driving to Corin Dam, then an all-day trek through some seriously rugged and remote terrain). The only road that goes anywhere near it is a long, rather dodgy unsealed road called Mount Franklin Road (and even that doesn't go to the summit). The route from Canberra is shown here: http://goo.gl/maps/nxS1HOWEVER, I guarantee you that Mount Franklin road is completely closed this time of year. So you won't be able to get a vehicle within 20 km of the Ginini summit at all at this point. It's one of the most frustrating things about living in Canberra. During cold outbreaks, we can see snow on the Brindabellas. There's terrain pushing 1800+ metres less than 50 km from the city centre. But you can't get there (or anywhere near there). So you have to drive two hours to the Snowies if you actually want to be in the snow, even though there's excellent snow much closer to town. I'd love it if they built a proper, sealed road going south-west from Canberra through the Brindies to connect to the Snowy Mountains Highway somewhere near Kiandra. It'd be great for snow chasing, and also cut huge amounts of time off getting to Mount Selwyn (or Melbourne, for that matter). But I understand why they don't - it'd be very difficult from an engineering perspective and that's a very environmentally-sensitive area. Plus the road wouldn't get that much use compared to the massive cost of building it.

Cimexus, the Boboyan Road traverses the Brindabellas from Tharwa to Adaminaby - its about half sealed at least. But, in winter can have snow and ice, mud and is very windy in places. I've done the drive several times in winter and summer and its a beautiful drive as you see the back of the Brindabellas, but not that much faster then going to Adaminaby via Cooma.

Yeah Boboyan Road is the closest thing to what I was thinking but it's pretty much due south rather than SW. A road SW will never be built though as it would have to go over the very high areas around Ginini/Bimberi rather than stick at least vaguely to the valleys as Boboyan does.

Hmmm how often does it actually snow at Blayney? i know it's reputation for being freezing but what about Snow falls? Blayney does quite well for snow. Its elevation is 880m, just below the elevation of Lithgow (900) and Orange city (920), but it is much better exposed to snow-bearing wind between west and SSW than Orange which is sheltered by Mt Canobolas and its ridge system to the W and SW, or Lithgow which has the high country around Yetholme to the west and the OP to the SW. In the 11 years 1965-1975 Blayney averaged 3.6 snow days/year with the highest being 9 days in a year, which puts it in the league of Cooma, Bombala, Crookwell and Taralga. The heaviest recorded snow event west of the BMs was on 5 July 1900, and my notes for then show that Blayney can hold its own with the best: Heaviest recorded snow event in the area, with heavy snow also west onto the Plains and north to at least Glen Innes. Russells report (AWN): "Railway traffic became paralysed, passengers being shut up in carriages, unable to reach hotels; in places snow 8 feet deep on rails. Telegraph wires down everywhere... Bathurst had a unique experience, all business being suspended; roofs, verandahs, and lightly constructed buildings collapsed under the weight of the snow. The phenomenal fall of snow at Bathurst [27inches] was surpassed on the mountains, and at places between Locksley and Rydal, it fell to a depth of 4 feet. The passenger train which left Bathurst was unable to proceed beyond Locksley." Blayney experienced similar conditions to Bathurst with snow falling from 5am to 5pm for an average snow depth of 27 inches. Subsequent snow topped this up to 3 feet with drifts to 6 feet. Other notable snow depths in the area: O'Connell 24 inches, Millthorpe 20 inches (3 to 4 feet in drifts), Parkes 4 inches, Molong 15 inches, Cowra 5 inches, Mudgee 20 inches, Wellington 4 inches, Forbes 9 inches, Carcoar 3 feet, Wallerawang 2 feet, Canowindra 1 foot, Hill End 16 inches, Orange 18 inches. Doug Shepherd's reconstruction (see AWN) shows this to have been an extreme small upper cold pool that developed on a surface low. The system also brought flood rains from Goulburn and Sydney southwards at the same time as heavy snow was falling. The references to "AWN" are in the Non-Alpine snow section [here].

Yes, I was wondering about that - the 500hPa trough moving up the coast has temps as low as -26. However, the 850 temps are barely on freezing with an 850 height of 1560m so I think snow anywhere is very unlikely unless something goes seriously awry.

Yes those were the days, even in the 1980's I knew a friend in Blaney and knew he was in an excellent snow area, some great snows back then in Blaney. So sad how much the climate has changed in only 20 years.

Uppers are now more like -27 to -28 on latest GFS & AccessR respectively. 850 temps too warm at this stage P.S. nice pics everyone - not a huge fall but certainly worth heading out on the OP.

Some would say we are mad wishing that to happen but not on this forum haha. Looking around at buying a few acres and all anyone ever says to me about Blayney is "cold hole of a place don't look there"!!! Between climate change, wind farms and coal seam gas maybe i can find a quiet little spot that will drop a little snow from time to time.

It now has quite a diverse base - Purina have a large factory/warehouse on the west side of town and around 400 miners from the Cadia gold mine to the west now live in town. All this in addition to its basic agricultural/pastoral base.
If you're thinking of a few acres at a higher altitude, browsing the windows of the real estate agents in Oberon is worth doing. They often have some very enticing farmlets or partly cleared small allotments in the Edith, Ginkin, Shooters, and Black Springs areas, and in between. They had a real beauty a couple of years ago - nicely equipped log cabin on about 5 acres, 1250m altitude, very secluded with great views to the SW. I was very tempted.

....Apart from as Andrew said today a weather station up in that area a nice hut with an open fire would be nice!!!!! Sounds like you would like the setup at Polblue camp grounds (1450m ASL) in the Barrington Tops. They got a cozy little hut/shelter up there complete with open fire, BBQ's & a picnic table! Does get quite popular though on those cold snowy winter days up that way. I chased there today actually, found the first settled snow at 1500m with isolated 1-2cm deep patches above this level. Not really any snow at Polblue which surprised me a little, but I did find the odd frost patch in shaded areas. There was also small ice type structures still amongst the grass, obviously from snow melt. My car thermometer ranged from 0 - 4°C across the plateau between 4 & 5pm this arvo but favored sitting on 0°C most of the way. Temperature at the aforementioned Polblue shelter on my thermometer ranged from 3.5°C dropping to 2.5°C around when I left. The fire was much warmer than that though hehe. I hope to have a report on my site over the next few days, when both time & my ADSL connection permits.
