Rain Event 16th December 2016

After an extended dry period with very little rainfall throughout the past few months, there is hope for some good soaking rainfall across parts of NSW and SW Queensland as a rain event develops. It seems a northwest cloud band is with in-feed of moisture along a change should provide the focus for storms and rainfall across the inland extending to the coast.

Rainfall amounts should be in the vicinity of 20 to 30mm across parts of the region including Sydney and the Central Coast with cooler conditions after such excessive above average heat. Great weather for the garden.

Giant Hail Definitions 5cm or greater?

Giant Hail Definitions 5cm or greater?

Dave Croan last week and now Jeff Brislane this morning brought up a valid point as to the definition of giant hail. Why us the definition of giant hail 5cm or greater in Australia? In the US the serious hail sizes tend to be near 10cm and in excess of that. I can only assume that it has to do with the return period of probabilities of achieving such an event similar to rainfall rates. How many people in Australia have actually observed or experienced hail 5cm or greater. In the US, probabilities are likely to be higher. What do people think? Should there be a standardisation of this definition for 'giant hail'? And I can confirm that there is no formal universal definition that I know of and Dave Croan did look it up just last week.
