Went up early, came down early thankfully. 7 car pile up on way down a bit past SkiRider and traffic at standstill on way up, maybe 70-80 cars with ppl plating in snow beside them to kill time.

*waves* welcome back

crazy drive back from Cooma this afternoon.

stuck In traffic. No actually accidents just people stuck in the snow. Some with chains some not. Two caravans being towed by disco’s are stuck on the side of the road. Just called the cops to tell them to get out there.

we were at a stand still for about 30mins or so.

Spoke to a met friend, the lower than expected snow level is due to evaporative cooling. The persistent nature of the precipitation has allowed it to drop the temp sufficiently for snow. Had there been showers not constant precip, insufficient cooling would have occurred and rain not snow more likely.

More or less, it's largely why models had those surface temps higher than observed, i.e. Jindy maxed at 2C from what I see, yet was forecasted to reach 4C.

It obviously, caught a lot out today.
BoM also didn't see it coming as they published a reviewed forecast at 11am today updating snowfall from 1100m to 800m.

Interesting how the BoM and Perisher Snow Stake have been out of kilter with each other.

Today BoM is registering less precip than the snow stake.

Last night it was the reverse. With BoM showing twice as much as the Perisher marker

The reason is possibly they reset at different times?

Its the first world problem of this event. Everything would typically be filled in if you got a classic 50cm westerly dump. But when its gluggy and falls straight down then the creeks will win. =The whole place will be like a marshmallow factory. Will set hard and next weekend events will blow around on top of it and finish the job.

MOD NOTE: Updated thread title not because we're 'down with naming WX systems' here @ ski.com.au but because one particular resort thinks it's ok to name/tag a weather system for commercial advertising gain. Not down with that etiquette so Backdoor Betty it is. ;)

Also updated thread tags for posterity and future reference of such a unique & flukey system.

concerns of wet-slab risk with this huge load on top of the melt/freeze crust on the weekend.

Driving to PV this morning was a once in a season event. Not so much the amount of snow but simply a lack of wind left so much weight on the trees. Lots of tree damage. Lower Kosi Rd was like driving in parts of Europe. Solid snow to quite low levels.

Plenty of snow at the resort.

Coming home to Moonbah at 1100 ASL the snow level had dropped significantly. For the next several hours we had some of the heaviest low level snow that I’ve seen in 5 years. A few random pics around the garden:

IMO

Easterly snow means lots of moisture, it should set hard as. But. It may mean things form a bit different to normal, so subsequent layers may behave slightly different in some aspects.

Moisture and Cold Pool headed North away from Alpine Region. So drier and warmer, IMO. Though some back-end in it.
