Popped into the PV thread. Thankfully the winds here in the leeward have dropped off.

Rain here on the leeward. Kicked off about 45 minutes back. Falling steady and just what the paddocks and water tanks needed. Has not dropped much on the mountains and Alpine thus far. BOM showing a few mm at PV. Monaro should be getting a decent drink. Garden happy to boot!!

EDIT: 19 mm for the first round. Nothing compared to all the northern rains however good to get it on these.......

50 mm ( total) rain here over 24 hours till today morning. It was interesting as my neighbour about 500 metres away received 44 mm and his neighbour about 300 m from him received 39. We all have rain guages and monitor the rain closely being reliant on it for potable water. Generally the results are pretty much the same but not this time.

Meantime this evening, watched this little cell develop off the range. Some lightning and a few drops of rain.

Last few days has really highlighted how isolated cells can be in the high humidity and highly unstable atmosphere.
Great obs as always, cheers.

According to my sources, heavy, wet sleet at the top of Kosciuszko Express in the last 20 mins.

It’s possible. There was a good temp drop as a band of cloud came from the South. Could see rain falling, a few large rain drops here on the lee and very cool outdoors. It was brief though. Pics as the cool air hit and after - timing is about right.

BOM showing Thredbo TS down to 1.7 degrees and 2 mm as it passed over.

Definitely fits better on this thread. Doesn't get much farther south than Nimmitabel in NSW…a mere ~ 50 km from the 37th parallel.

You sure love your thread policing, Homer. :whistle:

No, not at all. I learnt my lesson the first time. But the NSW/ACT Weather thread covers all of that area as well.
It was a pretty impressive picture and it's a shame it doesn't get more viewership.
That's ok though if you guys want to keep things south. Maybe there should be a Southern NSW/Snowy Mountains sub thread?
In the meantime, I'd hope it's ok to share that pic in the NSW thread.

Warm to hot westerly/norwesterly winds of reasonable strength blowing for the last 36/48 hours across the southern Riverina and South West Slopes +plains. Once you get off the slopes the ground and vegetation is getting pretty dry ...... again. Storms crossed last night without incident but it wouldn't take much .............. and there is plenty that didn't burn last year. Admittedly atmosphere has a little more humidity but still .......
Please be vigilant and thoughtful if traveling in the region especially if your a smoker.

Well to be fair, the precip pattern of the SW Slopes has always, traditionally, been one of a mediterranean nature, i.e. dry summers and autumms; wet winters and springs. Unfortunately (IMO), that long-term mediterranean pattern has weakened substantially, and abruptly, since the 2000s (source here).

Snowfall on the western slopes, in particular, has taken a major blow as a result of this pattern shift. Cabramurra SMHEA AWS (1996–2020) has warmed about 1° C in winter, and suffered a drastic reduction in winter precip of almost –100 mm (!), from the 1955–1999 station.

Well.......still waiting but somewhere on the Monaro and surrounds is getting a bit of weather.

Interesting that the cells I have been watching are predominantly from the SW however another has circled around from the SE. Dropped the temps and down-drafted some strong winds before going still again.

We drove out to Grosses Plain in a tropical rate late afternoon down pour yesterday with paddocks running rivers and a road under water.

Whilst not quite the smashing the South shore recieved, the North Shore also received a very good drink.

Below is a pic looking to the mountains 20 mins back. Plenty of days like this thus far.

Currently a cool day with no wind. 7mm rain here yesterday. PV picked up just under 3 and Thredbo TS under 5.

All show and no go here on another day of mild temps and overhead cloud......

Watched a neat storm however to the South for a few hours. It moved “towards the mountains” but (thus far) stayed well clear......

PV has picked up over 13mm in the past 60 mins.

We got 7mm later yesterday but sky was looking much the same as you saw it. Light field fog in the valleys early this morning but burnt off pretty quick.

Certainly a few hit and miss storms thus far. Local farmer 10 mins away picked up 75mm in 30 mins a few days back!

24 hrs till 9:00 a.m. this morning:
  • PV 31mm
  • Thredbo TS 16mm
  • Moonbah 14mm.

Brings the local total here over the past 5 days to 69mm. Handy rain across the paddocks.

It’s as mild a Summer (to date) as can I recall in recent years.

We got a decent puddle filler last night on the Jindy North Shore. There is a lot of activity but the downpours are elusive. Big thunder about 3pm followed by intermittent rain continues the tropical summer in the Snowys.

I must buy a rain gauge sometime soon.
You can borrow mine. Will give you the log in to see how much rain fell in the Jindabyne Southern Highlands.

Whilst I can see your place it's a whole different climate on South Shore Heights where the dark n stormy machine plies it's trade.

A little something-something to keep an eye out for mid-next month as we see the likely-errosion of the La Nina set-up. The dead-giveaway will be the blocking High SW of WA, which has already proven itself a stubborn piece this year already.

GFS still showing some promise for the upper slopes of the Alps, next weekend.
