This was a very lightning active storm in which many cloud to ground lightning strikes were observed , filmed and photographed. This was a storm that Jimmy, Colin and myself intercepted during a storm chase between Sydney and Newcastle during Sunday afternoon. The images demonstrate one of many storms that impacted the state during the event.
