Might as well slip a thread up for this because thundery events might be hard to find this spring (though hopefully later into spring and early summer it fires up).

Fast moving trough, dry at first but as it moves east it encounters increasing moisture levels due to the lack of a ridge cleanout from the moisture we had giving the storms out east yesterday and what not. Mostly afternoon timing, main trough in by prob 430pm or so when winds will switch to west to sw. Nice lift aloft with divergent uppers, fairly sharp focus as mentioned by Siera. Once sfc heated parcels reach around 10,000ft things will take off everywhere, not hugely active but I'd like to think more CG's than the CC dominated storms we had the other day. Inverted V profiles under strong speed shear as well on traces so I'd expect potential for severe gusts in stronger storms. Definitely something around to keep the SDS at bay, just don't expect huge totals, perhaps isolated quick 3-5mm dumps as cores pass over but due to the speed they will be moving, most likely totals will be under 3mm.

TS cool

It looks like it could be good, i'm wagering it splits north and south around the city

Doesn't there need to be something there before it's splits?

* some cloud there at least so all is not lost yet

Quite a decent band of active storms did form on the back of the ranges Cambrai/Mt Pleasant/Sedan/Mannum and marched off into the Murraylands.

Certainly not a fizzer for anyone who went chasing it east and SE but certainly no good for Adelaide. One rumble is all I heard, bit more moisture to the east which was expected an no surprises they took off more readily behind the ranges and over the flats. It was a low end event so not surprised in the slightest of the result, but was hoping for a few more bolts locally than the single one I saw.

Those were nothing but a couple little yellow spots on radar and threw out a few bolts for 5 mins before flatting into a monotone grey sheet.

Don't know, looked pretty decent as it went east through Mallee and SE, you must still use Sellicks radar if you only saw yellow!

Reckon if you had used Buckland you would have seen red and orange! poke Capture by Kym Burton, on Flickr
