Near average temperature in the morning and afternoon with the temperature a little variable from the mid morning to the early afternoon. As the temperature fell after the maximum temperature was reached in the early afternoon the temperature briefly became slightly cool and returned to near average from the late afternoon and back to slightly cool late tonight. Dew point has remained near average that rose slowly in the mid morning, fell slightly in the late morning, rose slightly in the early afternoon, then fell very slowly before stabilising late in the afternoon. Early tonight the dew point fell slowly before falling later tonight.

In the mid morning the relative humidity became slightly above average as the relative humidity briefly rose before dropping back to near average from the late morning while falling during the morning. In the afternoon the relative humidity became stable before rising from the mid afternoon while remaining close to average. Light S to SSW winds in the mid morning with some E to SE winds before tending SSE to NNE winds late in the morning. Light N to NE winds with ENE winds in the afternoon with variable winds in the early afternoon, light N to NNW early tonight, then WNW to NW during tonight before calm winds late tonight.

..., dropped into Hinzes Dam, beauty of a day and nice to see its capacity @ 94%'ish,, and the whole SE Grid not bad @ 57.5%, but if take away the 3 dams below 5%, this would change the average of the remaining 21 dams to be @ 81.7% not bad at all comng out of the dry season, funny only 12months or so ago, everybody worried about the Big Dry & Aus being burnt to the ground... can never tell in reality eh..
Hi @PlumbBob ... just a clarification. While there are over twenty dams in SEQ, the so called Grid% on the Seqwater website are 12 dams for which water can be supplied from them into the grid connected network.
The dams you mentioned below 5% (Lockyer dams) and others in the Scenic Rim region such as Moogerah and Maroon are not in the grid 12 dams total%.

The water situation is still quite tenuous in SEQ, grid 12 below 60% and Wivenhoe around 40%. Mandatory water restrictions likely to come in a short while if decent rains do not produce runoff into the dams (particularly Wivenhoe).

PS nice photo of the Hinze Dam spillway. I was involved in the design of that spillway. It was a great project.

I think I made this rather cynical comment a long time ago, but think it is worth repeating. Now we have a positive SAM, looking at the models, the usual lows and troughs developing over the central Tasman cutting off the moist expected onshore flow from the highs being further south. Looks like any weather,( apart from dry NWers and dry southerlies) is a long way off.

Hello,
Just registered. First time posting, long time lurking both here and on WZ.

Here's a couple of pics from last week in Brisbane River upstream of the D'Aguilar hwy showing the current trickle coming down.

Min of 0.9 deg this morning. We didn't get quite as warm as predicted yesterday reaching 21.4 on a simply gorgeous Spring day. Perfect weather for the Morgan Owners Qld group to visit the property however. Starting at about $125k, I have been advised by Mrs S that the price tag does not fit within our present "budgetary constraints". LOL

Hi Pete, i was of the understanding the SAM and IOD had changed this year to come on board to help lanina produce rain for us......perhaps it was a dream lol

As far as ENSO goes, it's been neutral albeit a bit on the cool side of it. The majority of models are still trying to cool it further towards La Nina territory as we get towards late spring/early summer but that's where some uncertainty comes in i.e. whether it'll go into a full blown decent La Nina or whether it'll be a borderline Cool Neutral/La Nina phase.
1st forecast graph above is from the range of models from the NMME suite.

Meanwhile the IOD's generally been in a weak negative phase and it's considered likely to gradually drift back more towards neutral come late spring/early summer. 2nd graph is from CFSV2 - it was initialised last month so it's a bit outdated but that should be updated any day now.

I know I've said this many times over the years but it should go without saying that regardless of whether there'll be a full blown La Nina or not (or a continuation of the weak negative IOD phase), there'll always be some areas and months which are exceptions and miss out on the typical rainfall and temp patterns historically associated with ENSO and IOD phases.

On another note, also above is the latest TC activity outlook for the upcoming Oct 2021 to Mar 2022 period from EC.
Use with lots of caution though because TC's are highly sensitive to shear and that can easily make or break a longer range TC outlook. Any factors trying to sway things towards an above average TC season will also have to fight against the overall longer term trend of decreasing TC frequency over Australian waters.

This season will tell all for Central Queenslanders. If we manage to come away with a rainy season that is more typical of a La-Nina year then all is not lost and we may just get away with marking down last year's horrendous as extremely bad luck; but if not, then I think it's time we have to start seriously looking into why that is and why those regions which once were influenced by favourable phases of such climate drivers no longer are.

So far the -IOD has been really underwhelming for many parts of Australia (TS made a couple of really good posts on this in the Climate Drivers thread). However, that's not to say it's not there at all, as noted in this tweet by Andrew Watkins:

In addition to my haze rant earlier (spurred by a client whinging about CBD visibility)
I heard my first Stormbird call late this afternoon. I no.longer rely on them for rain prediction due to past discrepancies, rather for me they herald a of change of seasons.

Yeah I've lost count of how many times I've heard them go off during past seasons, only to be followed by more and more dry stormless weather. They do sound eerie though.

Weird question, I have noticed that although it is clear here there seems to be a lot of haze. Especially Tuesday morning when it technically should have been clear after that little front moved through on Monday and there was yet to be any burnoff fires locally that day?
Is it possible the smoke has blown up and blanketed from Vic with that Southerly wind Mon/Tues as I have just checked the satellite and saw this, this is bushfires yes?
I tried to attach my QT file of the satellite animation but was too dumb.

Screen Shot 2021-09-09 at 1.40.54 pm.png

I actually had a close look at that and believe it or not, it was plumes of cirrus even though it deadset looked like bushfire smoke at first glance.
You could see the heads of a few of those plumes forming over water just south of Port Phillip Bay and some off the Gippsland coast as well.

It looked like they may have formed due to the flow being forced to rise over rough elevated terrain then descending before "rebounding" back up and this upward motion transmitted into the upper levels where the cirrus formed. The air below the upper levels was probably too dry for any other lower clouds to form below the cirrus.
That also looked consistent with the fact that most of the heads of those plumes looked like they were just downwind of higher terrain.

This sort of "bounce" can sometimes also be seen over Melbourne when there's patchy rain or showers around in northerly flows where you see a lot on radar just to the north of the city, then a clearer gap around the city, followed by a mass of heavier precip reforming to the south of Port Phillip Bay.

Interesting - I go by either of the cuckoos - Channel Bill or the common Koel. Haven't heard either in Paddington yet, but I presume the crow rookery close by is gearing up to be cuckolded.

anyone any Intel as to what aircraft are dropping it? Use to be an ABC TV promo that featured a Hercules firing off Mg? flares which I presume also included chaff? Very impressive. Could have substituted this display for the old FIIIC D&B at Riverfire

The majority of our Air Force aircraft types have defensive countermeasure systems. For example, our F/A-18F's and Growlers have chaff/flare dispensing systems which can carry lots of small chaff and flare cartridges (together with the capability for expendable towed decoys). They're integrated into the countermeasures system whose software and receivers continually analyse and prioritise threats so the countermeasures can be released in auto, semi-auto, or manual modes at the right times.

Australia also has a couple of highly modified Learjets from Raytheon which provide electronic warfare simulation for our jets and also carry chaff that's part of their EW suite but they're normally based at Nowra from memory (one of them's contracted to the Navy while the other one can do stuff outside of that contract).

Interesting bird talk, no storm birds yet.
Of interest, we had a family of crows living in the neighbourhood. Not a real fan of crows.
But last week the hole lot just disappeared. Havnt seen them since.

Subject of Chaff and how handy it is with the radar...grrr.
Never seen the stuff in person, when it falls to the ground, can it be seen on the ground, pool etc

Never seen the stuff in person, when it falls to the ground, can it be seen on the ground, pool etc

You’d be hard pressed to see any of it lying on the ground because it’s so finely dispersed by the wind by the time it eventually reaches the surface.
Maybe some thin strands if really lucky and you happen to be in just the right spot. It’s like looking for a few needles in a haystack.
Chaff’s designed to bloom out rapidly once it’s released rather than stay in clumps that fall quickly to the ground.

The fact that you can’t even see any of it as a kind of haze in the sky even when the weather radar’s filled with their echoes is testament to the small amount = very high radar reflectivity quality of it and how much it’s dispersed by the winds.
Think of throwing out some compacted bundles of fine human hair from 10-25,000 feet which then spread out immediately.
The only exception is if it’s released from lower altitudes in which case, you might have a somewhat better chance of seeing more of it on the ground but even then, you’d have to be in the right spots and the footprint on the ground is smaller.

I know September is a dry month, but am seeing a resemblance of last years failed storm season
Plenty of fronts moving through but all dry....

Perhapa our storm season is now winter lol

Haha feels like that doesn't it. Bring on next winter!

There seems to have been quite a few seasons in recent years where we've had a big sudden flurry of storms and rain in October which then becomes really quiet right through til around Dec/Jan when there's another period of night-time electrical storms.

And the one or two highly destructive storms mixed in.

In other words, quiet overall except for an intense start early on, but which doesn't last.

sort of sounds like concentration of activity in time and space
which then sounds like what I understand could happen with climate change
not saying it is climate change… but alignment with what is expected to happen with CC don’t appear to be deniable
I better stop here enough said.

We're on 24 deg now with 81 percent humidity and a light NE seabreeze looking at the Meteye this is going to change tomorrow, still warm but humidity expected to drop 50 to 60 percent less for some reason.

That's because today's northerly type flow there is going to be replaced by drier S to SW'lies tomorrow.

We'll be getting southwesterlies down here tomorrow and they might become breezy at times in the afternoon as well before southerlies come up over us in the late arvo or evening.

Some isolated small showers have popped up in our region but as expected, they've been having trouble getting past the big layer of warm air in the midlevels so far and flattening out into altocumulus. Maybe one or two might just throw out sparks if really lucky but I can't see any kind if widespread storm outbreak happening over land today.
Above: EC sounding for 2pm near Brisbane where you can clearly see that layer of warm air aloft.

Also above are some nice clips of ice shoves (caused by strong winds and thermal expansion) as part of the series on cold weather phenomena I've been doing elsewhere for those who want a virtual break from the humdrum of the current weather here.

Haven't seen them for a while thought that was the end of them last month. Is that due a low or cold front further south?


I enjoy drier air though today's isn't exactly unbearable eg currently

We are on 23.8 deg feels like 22.6 deg but Rocky is on 31 deg feels like 30 deg. They have hot NW winds , we have moderate cool but humid NE winds :)

Well morning spent on the vegie garden has been rewarded with a downpour this afternoon here in Kingaroy.
First one for a while & the smells are exotic, in a nice way.
Hope this video works out, I don't post videos, lol.
I love watching the Galahs when the first rain comes through, they've been put there for a good 20 mins having a shower & playing.
