Great you were able to photograph the early development and spectacular mammatus Kane. I was pretty much stuck at home till late afternoon.
----
Full on altocumulus castellanus in the morning !
Anvils from the west spreading across with congestus on the Border Ranges - this later became a thunderstorm.
Was not expecting to chase at all as had some family commitments late arvo / early evening. Fortunately this was called off at the last minute, so headed to Wyrallah south of Lismore for a look at the storms coming up.
There was an shelf cloud structure forming along the N-NE side of the new updraft area, and a microburst south of this on a decaying storm. Thunder was constant but only saw a couple of CGs. I was a few km east of where Rodney took his first couple of photos.
The new storm was now over the Lismore Kyogle Road sort of area, so I decided to head west along the Bruxner Highway and watch the back of the storm. Regular powerful CGs hit around the southern flank of the storm and in the precipitation core (according to Rodney and Beck). It was a beautiful scene though difficult to capture the fast bolts. Video will have got them though : )
Moved to Casino area to watch the action slowly move to the north. There were also move storms to the south and southwest.
Caught up with Rod and Beck and we all enjoyed the late afternoon and early evening display before it all started to dissipate after 830 EDT.
