The dust storms that swept through places like Broken Hill today have been showing up well in the specially-enhanced dust imagery from the Himawari-8 satellite.

The CAMS dust products are still trying to advect some dust haze over SEQ by tomorrow evening, lingering through Friday and then possibly again around Sunday but its concentrations (<75 micrograms per cubic metre and aerosol optical depths that aren't TOO bad) are more suggestive of a dust haze rather than a full blown DS. That's if it even reaches us.

I did see some talk earlier about rainfall and the dust - one thing to note is that most of the first lot of dust haze looks to be in the clearer air in the westerlies behind the rainband so I don't think the rainfall will help wash it out of the sky as far as our region goes.
Will have a look at the rainfall, winds, soil conditions and instability west of us to see if any additional dust will be kicked up or not.

Thanks for the map Ken, I'm presuming this dust chart is only exclusive to the BOM?

Only about 2.5mm here so far, fingers crossed more to come.

Loc: Tewantin 4565
Just moved to Tewantin from the South Coast NSW.
Decided after a long time Id go for a chase, ended up in Dalby to a very short and sharp storm around 3pm. Caught another one at Nanango.
Bothe were very short lived.
Seems that they were breaking up just west of the ranges north of Toowoomba.
Alas, tomorrow is another day.
Bit too late to post up shots of the structure, it then again it was very disorganised. Not much to look at.
870kms later, Im hoping for something worthwhile tomorrow.

Love your commitment, yes when it's rain embedded storms and lots of high cloud, I find the storm structures are no where near as good compared to chasing individual cells with no other cloud around

Looking at the radar struggling to see where this 95% chance of 10-20mm is going to come from as per the Brisbane Forecast. Another BOM fail?

Access - C has activity over the SE QLD region late morning and early afternoon before clearing.
I'm hoping some of the high cloud sticks around at sunset, could give off a awesome red sky, considering it will be clear out west later on.

The dust mass chart forecast on windy has dropped values on the latest runs.

Strangely though, Sydney's forecast is for raised dust, yet there values are way lower compared to northern NSW / Southern QLD. I'm not too sure if there are other models that forecast dust, other than the one on Windy.

Maybe those values will come on the way of storms later on? There is a small rain band just east of Warwick, appears to be heading to the southern area's of SE QLD - Gold Coast etc..

" Very high (90%) chance of showers or patchy light rain and the chance of a thunderstorm, clearing during the afternoon.
Possible rainfall: 10 to 20 mm
Chance of any rain: 90%
"

Today's Brisbane area forecast means:
90% chance of more than 0.2mm (minimum measurable amount of rainfall)
50% chance of more than 10mm
25% chance of more than 20mm
[over the 24 hour period from midnight to midnight]

Hmmm, yeah that was a rain fail with the amounts forecast and what actually fell. Gfs downgraded from 30 to 3 yesterday morning which was pretty spot on, but then they upgraded it again later in the day. EC had 20-40mm falling which was nowhere near what anyone in the area received. Models seemed to really struggle with this one. Shame, we really needed the follow up from October. See what the rest of today brings.

If you look at the day/night satellite on the BOM, you can see the impressive dust storm in a orange tinge colour

When the rain clears and whatever totals eventuate, whether it has been less or more than forecast, there is one thing to consider. As others have pointed out, there is going to be a highly unusual(probably not unprecedented), extended period of hot dry westerlies. When it finally ends, what is going to come afterward?
