On this day 9th December 2007
Today is the 13th Anniversary of the Blacktown supercell hailstorm where I got clobbered with >8cm hail confirmed and measured in the same spot by Jeff Brislane after I was there.
It caused millions of dollars damageI continued to chase this storm with a new storm or updraft neat Toukley with golf balls.

I remember this one very well. It caused some $461 million damage in insurance costs at the time.
