DISCUSSION: As a low-pressure system gradually moved across parts of eastern Australia during day on Monday, there were several areas that were impacted by severe thunderstorms that (in some cases) produced instances of small hail as well as as strong damaging winds. These type of events are quite common during the heart of the Southern Hemispheric summer as a result of the fact that even low-pressure systems which propagate across the Australian outback and cause shorter "pulse-type" air mass thunderstorms often do not last for an incredibly long time. However, while they are at their maximum intensity and as these convective storms ingest available atmospheric instability in their vicinity, they can often become rather intense. As shown in the footage above (as captured by AndrewandShelly Johnston) clearly illustrates this concept as this house located in Mona Vale which is a northern suburb of Sydney, Australia was hit by small hail and strong winds from a brief severe thunderstorm which propagated through the region.
