The first real taste of winter will be coming up late this weekend.

Yr.no is predicting up to 30cm of snow for Perisher on Sunday night into Monday (assuming that 1mm of rain = approx. 1cm of snow) and even about 15cm for Thredbo Village. GFS is also going for a lot of precip, likewise with ACCESS.

As I said in the other thread, a few cm of snow at places like Shooters Hill in the CT's is certainly possible in the early hours of Monday morning.

On the coast it's likely to be very windy with a low out to sea showing up on AXS and GFS. As winds turn more southerly on Monday arvo, there will be a few days of showers and breezy conditions as well.

It certainly looks like a significant change, with the BOM firecasting snow above 1200 metres in the Southern Ranges on Sunday night / Monday morning. Meteye shows a extensive snow over the Southern ranges, but no stray pixels further North.

Monday looks like the coolest day in Sydney for a while, with a forecast of 12 to 20.

The following week looks cool and showery on GFS, cooler than the BOM's forecast. The BOM seems to think that the coast will be under high pressure by Thursday. We shall see. We need to stop the high from ridging along the Southern edge of the Tasman...

Looks like the proceeding trough is being fed from the NW cyclonic action.
This low looks pretty nasty. Not overly cold, but very very moist. I'm thinking 30cm's plus on the main range

Even though that seems to be an optimistic forecast, I tend to agree.
Thredbo forecast going for -3/3 degrees on Monday, with 15-40mm predicted and it should almost all be snow. Winds are going to pack a punch too.

Picture perfect autumn day today by the look of it so far, as was yesterday, after a cool start. (love those higher diurnal ranges in autumn and spring with cool nights to warm days, we have not have genuine shoulder seasons in recent years).
Back to low 20's tomorrow, but going away tonight for a week, so will (not) miss the return to more rut weather.

Yes Derek, a beautiful day and the warmest for quite a while.
Currently 24.4 degs with a light NW'er blowing.
"Thunderstorm likely" the forecast says.
It should start snowing in the next 4 or 5 hours on the alps.

Was about 26C with breezy northerly and sunny earlier, which is about as pleasant as it gets. In the last half hour, mid level cloud has closed in very quickly. Still rather nice though.

A beautiful warm, DRY, sunny day today with light to moderate NW'ers and temps around 27 across most Sydney sites. It would be nice if we could sneak in a last 30 before the change, but that won't happen.

Cloud is approaching from the West. Camden, Campbelltown and Bellambi, under cloud, are at around 24-25.

Meanwhile in Melbourne it's a 'refreshing' 12.5 degrees. That change packs a punch.

EDIT: nice pictures WR and also Eddy from yesterday.

There's a chain of storms extending along the South coast from Bermagui North to Ulladulla then extending NNW from there past Bowral, Oberon, Bathurst and on past Dubbo to Trangie. That might mark out the front. Orange Airport, apparently behind the front, dropped from 16.3 to 9.9 degrees between 3:30PM and 4:00PM.

EDIT: Thredbo top station is on -1 with precipitation, so it's probably snowing there.
