Kazz . Have a look at this article. It gives a very good account of the reasons it was stopped by the CSIRO. It just was not very successful.

Yeah Rod, I have read that before but will go back & read it again in case I've missed something.
But I'm not suggesting it as a recurring thing, but as a one-off hail mary if they can find the right kind of cloud masses.
Because at the moment the only thing we can do is the 'hail mary' loads of hay & money - they won't solve the problem either but probably cost just as much as a cloud seeding exercise. At least with cloud seeding, the results are a little more residual until Mother Nature kicks in.

No storms today with all that cloud Cover. Can't complain one bit though nice drop of rain round here about 50mls so far

Yesterday (Saturday) at 13:12 hrs critical power lines tripped between Dumaresq and Bulli, creating havoc across the National Electricity Grid.

Was storm or heavy rain occurring at either of these locations at the time?

There might still be some areas which do get thunderstorms today despite the current cloud cover. There's fairly good dynamics with this system which may contribute to some embedded thunderstorm activity within (and possibly near or behind the rear edge) of the cloud band during today with the instability.
There's already been some isolated lightning detected to our north.

One of those situations where cloud cover doesn't necessarily dampen down all activity.

Wow must be unstable alright!Very cool and overcast with 100pcent cloud cover here I guess in places that have breaks in the cloud cover stand a chance as ya said Ken.Also an amendment to the rain totals here our rain gauge is near the garden and my wife tells me she gave the garden a soaking 4 days ago so it's anybody's guess the rain totals here

Ken where is the dryline though? I'm presuming storms can still form east of the dryline?

There's no really pronounced dryline in our area at the moment (may become more pronounced later) although there is a narrow dry slot over the NWSP in NSW wrapping into the northern flank of the system - in the combined satellite/lightning/dewpoints obs/surface wind analysis below via Weatherzone, you can see a band of thunderstorms between that dry slot (marked by the lower dewpoints) and the area of slightly more moist but unstable air wrapping around the rear flank of the system. These storms are in the somewhat clearer air behind the main cloudband but there's still instability there helped by the cold air aloft lingering in that area associated with the low:

Plenty of pea size hail or smaller here. Strong winds to begin with. 25mm. Great little storm for August. But now it's back to dry dry dry again.

Who let the sun out?
10.5mm, calm, warm & humid with lots of fluffy darkish clouds moving eastish.
Maybe enough heat to cook something up?

Slightly less Elf with 10mm total here in north-east Warwick. Better than nothing of course but will have a net worth of nothing without immediate follow-up. Good to see better falls in other areas.
