Activity was restricted to NSW until later in the afternoon. In the early evening storms were developing along a NW / SE line with a particularly impressive cell near Mulgowie:
I figured I was too late to try for Marburg to get onto the NW edge of the cell, but most of the lightning seemed to be dropping on it's eastern side anyway. We ducked up to a local spot and I was surprised by the view we got considering how far away it was.
The next shot is a little furry but I include it to show the structure of what turned into a very defined roll cloud.
It was close enough to the storm to be called a gustfront or shelf cloud, but considering it didn't seem attached to the cloud base, I'll call it a roll cloud. It became beautifully defined as it approached:
Almost on us:
The storm was now weakening as the roll cloud passed overhead.
CGs had already become very infrequent but the storm did give me one more as the rain started.
Shortly after this, the storm died and didn't even make it to the water. The southern end of the line however continued well out to sea.
Around 12:30am, more stuff appeared out west just this side of the ranges. At around 3am it arrived in Brisbane.
Plenty of cloud-to-ground bolts landed on the northern and southern end of this line with little for us, until:
It was almost a repeat of waiting all night for some decent lightning and finally scoring one great bolt. We eventually got home around 4am.
