Later, on the way home around 5pm, as I was heading down through Rhodes I could see storms were firing to the NW. As I got to the Hume Highway I was impressed enough to pull over and give Paul a call as he was on the forecast desk. Not being an ideal situation for long-lived updrafts, I knew that the storm of the moment was out of reach (up near Glenorie), nevertheless I was drawn north by some nice updraft pulses on the southern flank and darkening skies (was in suburbia so could not see much at the time). As I crossed the Hume Highway overpass, a nice dark sky became visible
It was peak hour and I just wanted to get off the road and get a look, so I ended up on top of the DFO carpark on the eastern side of Homebush Bay Drive near Olympic Park. The storm at this point looked impressive with frequent Cg lightning and a dark menacing appearance
I was even more surprised that there was a decent low-level circulation evident with a bowl funnel at the centre of the circulation. Not only that there appeared to be a clear slot working in (will post video when i get around to editing it). As I was watching, it occurred to me that was going though the same visible process as the Attica Ks low-level meso (I was in a similar position, looking almost up) -- except that it was brief.....5 minutes or so, and smaller in scale.
The lightning was close and becoming very frequent. In fact, immediately following the demise of the circulation, there was a barrage of CGs!
I retreated to the cover of the carpark as rain began and the CG's continued, it was quite a show. Next door was a power substation so I pointed that way. These are very close bolts accompanied by immediate gunshots of thunder!
