Hailstorm

Storms have been ongoing throughout Victoria over the past couple of days spreading into NSW. Some interesting pulse cells developed with some impressive anvil shields due to deep convection. Temperatures in the upper levels at anvil level have been rather cooler than I have seen it for many years. So the lapse rates in the upper portion of the atmosphere have allowed for some rapid development including the odd overshoot on pulse cells even. This has also enhanced the conditions for hail development once storms can tap into the upper atmosphere. Mid level temperatures have also been rather cool warming up yesterday as the ridge strengthened. We’ll see what happens over the next several days. At least moisture is no issue from now on. Sydney and the North Coast should be in the firing line over the coming days.

Finally some significant rainfall across the Sydney region and south along the coast. Some heavy falls occurred in the parched South Coast where water restrictions are about to be issued.
The rain began overnight Friday as thunderstorms streamed in from the northwest. Some hailstorms amongst the many cells that developed and rapidly drifted towards the coast. Most of the more consistent rainfall however occurred on 3rd October. Models seem to indicate a wet pattern and relatively cooler weather at least for the first part of October.
Meanwhile, in contrast, bushfires and heat waves conditions persist in Queensland and parts of northern NSW.

The Melbourne hailstorm does appear to be unprecedented for Victoria in delivering gorilla sized hailstones. Hailstones up to 10cm diameter were reported by a Bureau observer south east of the CBD. The damage to vehicle and roofs in some areas leaves no doubt there was massive hail. Most other suburbs along the storm track appear to be mainly golf ball size. The very heavy rain also caused widespread flash flooding.
