The 16th January 2008 severe storm developed reasonably explosively. From a better perspective at Prospect, the circular base structure indicated the storm attempted to organise for at least 40 to 50 minutes over the western suburbs. The result was strong downburst winds achieving severe criteria, large hailstones probable about 2cm in diameter and extremely heavy rainfall. The hail as per usual was very localised and intense when it fell at one point. The damage caused was just not welcome particularly since it was one of the few storms to hit the same region affected by the western Sydney hailstorm December 9 2007.

The 17th December 2005 saw widespread supercells develop across eastern and north eastern NSW. The storms dumped large hailstones in the region near Gloucester and Taree whilst areas further north largely missed out on much of the activity due to drier intruding.

Meanwhile, a violent high precipitation supercell produced extreme straight line winds and very large hailstones on the north coast. Extensive damage occurred between Lismore and Casino.

High instability and relatively low shear dominated the models early on the 31st January 2008. Storms did develop in a line near Picton. Gradually these exploded with some impressive updrafts and backshearing. The storms never looked like weakening but did form a line of activity after the initial cell. The storms dumped heavy rain and hail near Wollongong and then progressed north. It was the outflow from this system though that initiated more lightning active storms in the southern Sydney suburbs. The system followed the same behaviour and more storms developed again over the northwestern suburbs of Sydney.

Very heavy rainfall, flash flooding and damaging straight line winds once again created havoc. The combined winds and lightning caused massive blackouts to be restored well into the morning hours. It was one of the most active lightning storms observed in the area and some areas received hailstones for period of aprroximately 20 minutes.

During a week of extensive severe storms in north eastern New South Wales, the 11th October 2007 was to be more of a reprieve for the Northern Rivers. But an isolated severe thunderstorm developed in the western part of the region and progressed eastward. Apart from the copious amounts of hailstones, the storm exhibited both interesting structure and behaviour of the base. It seems the storm showed supercell characteristics.
