Hi Dunk,
Thunderstorms such as this in Sydney are not only normal, but have been conspicuous
in their absence over the past few months.
As you can appreciate from the recent bush fires, with the coming of tonight's shower
there are many us who are breathing a collective sigh of relief. Having said that,
all it takes is for a couple of hot days again and much of the moisture can be gone.
A common meteorological phenomena in the warmer Sydney months is the
"Southerly Buster" where after a hot day and typically either in the afternoon
or evening, there is an abrupt southerly change with strong winds.
The temperature can plummet 10C to 15C in less than an hour.
Sydney typically receives about five a year.
However, tonight's storm is not a Southerly Buster.
