Hey. great you have an interest and prepared to step out of your comfort zone.
The maps you were looking at are surface synoptic charts.
Looking top down on the southern hemisphere side of earth.
Antartic in the centre, the polar belt of lows surrounding the antartic pole ,the belt of mid latitude highs and the tropical zone of low pressure up near the equator.
...
Comparing the changes in the 2 maps with a declining AAO over 3days
As one would expect the polar belt is expanding with a de lining AAO

and probably not what l expected.>> The mid latitude highs are becoming larger (not necessarily higher pressure)
Some increased excursion of the low pressure polar belt between the highs.
Checked jetstreams tonight.The tropical jet very zonal(non wavy) and contracted south. The polar jetstream , some increase in wavyness but minor this week. Jetstream streak speed increasing.
......
I have been foolish in 'jumping the gun' with conclusions as one should never preempt results.
here is another variable to consider
I Found this stratosphere(upper layer air) temperature anomaly
today. Notice the cold anomaly took place during our summer 2018/2019 severe warm dry weather and the notorious stalled Tasman high.
Another input to my research to consider.
The graph below is for the mid riff around the earth. Say rockhampton to equator in the SH and the same distance into the NH
cheers

BTW
I checked the 10day ACC and what looks like a sub polar excursion heading to the Bight around the 24th. So l just have to bide my time

Might be the same widespread cold outbreak over southern and eastern inland parts of Australia that many members of the EC ensemble were going for towards the end of this month or start of next month (when I last checked yesterday).

After a fine day, showers and drizzly periods began moving ashore here around 3pm this afternoon. 20.2mm has fallen here since 9am.

Looking at GFS's forecast sounding for 4pm at Roma, beginning around 2000m above the ground there was very moist air. However, it was quite shallow with an inversion beginning around 2700m, which would have restricted the vertical height of the clouds to that pocket of moist air.

Remember that nov' 2018_march 2019 stalled Tasman high and the low onshore rainfall.
Well so far the driver situation was Pos AAO,a strong cooling of the equatorial stratosphere , a sudden stratospheric warming in the NH pole. and

a sudden massive drop in the SOI from positive to negative during that time period

So is a strong declining SOI known to reduce onshore rainfall on the east coast as a general rule?

http://www.bom.gov.au/climate/enso/#tabs=SOI

I am noticing that on this Ec rainfall map we have rain signal on east coast from onshore this week.
https://www.weatherzone.com.au/news/wet-weekend-in-sa/529721

Our current situation is
declining el nino symptoms in the 3.4 region
SOI has trended toward the positive
AAO has gone sharply negative

I wonder if this is the combination for wet onshore activity.?
The clouds were so thick and water laden today. Lots of cumulus around as well

Appreciate that link Ken. Thnx. I will chew it over in the coming days',regards
Some 'beefy' showers have just come through at the tweed. Looked like not much on radar but we have been getting about 7mm past dark nearly every day over the past week.

Hey everyone, so quiet!
Thought I'll put this up to distract the boredom. Drove to Gatton early this moaning just after 6am, yes, moaning, wasnt happy, and saw the moon setting waaay too far to the South for my liking, usually sets due W of us over towards Hampton give or take a few degrees in winter when the moon sets more to the south. Didnt have a compass with me in the car but it just looked really strange. Might get up 5ish tomorrow and have another look.

I'd say it's quiet because there's still virtually nothing happening weatherwise for the foreseeable future apart from some coastal showers smile

Above are some autumn-themed photos I took of the sweetgums and Red Maples in their autumn glory in Toowoomba this afternoon. Temp was a pleasant 18C at the time with feels-like temp of 13C.

how ironic you post those pics Ken...on the way home from Jandowae today we drove through Toowoomba about 3.30 p.m this afternoon, i very nearly stopped my vehicle to photograph the Autumn colours of some trees I saw on the side of the street there. I wound down the window on my 4wd as I drove into town and made comment on how cool it felt outside, pushed the vehicles outside temp gauge button and it said 19C, but certainly felt cooler with the breeze of the vehicles movement.

So far only one day in May without measured rainfall at Sunshine Coast Airport. April had 5 or 6 (one day missing measurement). No day over 40mm of rain. This compares to the groundhoug day weather of January - 30 days without rain, one with 0.4mm, and every day max between 29.1 and 30.4.

Great pictures Ken. My wife has coerced me a couple of times to drive her around Toowoomba to take pics of the trees. Yes Namarrkun, the wind in Toowoomba always seems to feel cooler than it is. This weather pattern seems to have no end. If we start getting westerlies and frosts without rain when winter arrives it's going to be a cruel winter away from the coast.
