Looks like the Sthn half of Aus will cont having some jet for a while yet, ,

And wind speed, but more-so, directions at different altitudes, hence, instability. Then there is moisture/vapour content !
It's like needing the right conditions for storms to develop, not just a trough, but also many other influences all working together, just right, for a good storm session  and they are apparently yielding more ferocity these days !
All in all, a rather 'unsettling' topic, huh

Ah, a good storm session would be nice! (though no large hail, please

), we just have a lot of clear skies and bad seeing! Working out when it's good is a right old dark art too, though I think Skippy Sky has just about got it over Meteoblue recently for me. Hope you get some settled skies soon
