Central Aust severe storms 18-19 November 2008
« on: 20 November 2008, 01:37:12 AM »
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.

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 ...

Trevor Acton from Darwin sent me these images that he was given from a work colleague who was there for the severe storms and the hail!  The landscape looks like something from the eastern states during winter except for the steam in one of the pics rising from the ground and the last photo shows some decent sized hail underfoot.

 My thanks to Trevor for supplying the images as it's something we don't always get an opportunity to see this kind of thing when it occurs.
