Quite a nice hailstorm yesterday afternoon at my place. Stones were only up to 1cm but there was a fair quantity amongst some torrential rain. A few very close lightning bolts hit nearby. Hail also occurred at Ballina and Lennox Head.
Instability remains but it is a lot cooler today - more info here
