I will not add much to what Jimmy has already said about this event except that i was too late for the first supercell near Appin due to family commitments but I was able to get to south western Campbelltown in time to witness the new second supercell develop and chase it all the way to Heathcote Road and intercept it Menai. I then backed off away from the rain/hail core to Holsworthy and watched this storm until it started to collapse. I then headed back down to Appin, met up with Jimmy and watched an amazing supercell on sunset which developed over the mountains to our west.

  1. Jeff Brislane, interesting motion being anticyclonic! So was this the anticyclonic couplet? I think there usually is an RFD (Rear flank downdraft) cutting in somewhere which I may have observed. This storm was very interesting to watch as well as confusing as this particular cell developed on the outflow of the original supercell!
