Well, I'm not particularly excited at this stage hehe.
I will reserve energy for January / February, or is it may / June, but for the time being there are are a few upper waves pushing through. Cant rule out the possibility of some thunder, perhaps even a nice surpise, but it is really hard to be too enthused.

Hi bustchase,
It seems to have degraded at this point. There will be storms but not worth the fuel going after them.

Hi Guys,
I got some nice timelapse of the later cells that formed in Sydney around 3pm. I'm putting together a small slideshow to see what they were like.
I got some nice pics of the lightning early saturday morning as well. There were plenty of multiple cg's around 6am.

Hi Jeff,
Can you post those pics and links to the timelapse!
That would be awesome! Just a note that technical discussions are invited in the advanced section of this forum.

It wouldn't let me post an image yesterday from my hard drive. Kept getting this error. Can we post from our hard drives or only from the web?

Thanks Mr Deguara.
Can I ask, why do you think such a sculpted supercell developed on this day near Taree. It seemed to me, although I am not so experienced at this stage, that winds at all levels were from the west, except at perhaps the very surface. Yet the supercell suggested a structure that I would expect with deeper easterly inflow? Were the storms long lived?
Cheers

Hi Darren,
This storm apparently developed in a regime where winds were upper northwesterly though the lower level winds were from the south east but in the storm environment very light. I am wandering if there was a boundary to its north or if the storms on the day were hitting a boundary becoming severe and then collapsing. According to radar this storm developed well west of Gloucester and moved further east of my location still reasonably intense indicating it survived for a long period of time. It may have been more of the low precipitation variety earlier in its lifecycle allowing time to build up rotation and then in this region it crossed a boundary of perhaps deeper moisture. There is also hilly country it has to contend with which will affect some of its structure.

Right, I see! Thanks for the explanation. When you say a boundary to the north do you think the weather observations from the region could be used see if this was what happened? Were storms to the north higher based I wonder indicating a dryer PBL? I must say as I keep viewing the images, the storm you photographed is really incredible. I would like to see something like that.

Hi Darren.
There is definitely drier air instrusion on the northern side. A storm that occurred there which was quite strong totally collapsed within 15 to 20 minutes. These storms however continued towards the coast! It was an incredible day.
