Did anyone have a look at the setup over parts of Central Australia today ? There's been severe thunderstorm warnings out for parts of northern SA, southern NT and NW NSW as a result.
That's a pretty special sounding from Giles.
Giles
Alice Springs

23z/17 Giles sounding is scary: deep moisture that will not mix out sits underneath
a cap that is stout but breakable, with a dry adiabat above it promising buoyancy nirvana
once initiation has decided to take place. A broad subtropical jet sits over the entire area
providing adequate deep layer shear for supercells. It gets better: given a rotating storm
near that warm frontal?? boundary that I am hallucinating about in the very sparse
surface data N and W of Coober Pedy (northerlies backing to ENE-lies), whatever/whoever
lives in the general area might just get treated to something very special with
rotation near ground level ...
