New South Wales was alight with thunderstorms today, with some of them severe. A trough ahead of a low pressure system was the culprit for these thundery displays throughout the day. As it shifted east, thunderstorms began firing up from the early morning around the Northwest Slopes and Plains and Southern and Central Tablelands. A few supercells emerged around Cowra, Grafton, Orange and parts of the Hunter, bringing hail, damaging wind gusts and heavy rain. Cowra saw six millimetres in just ten minutes while Orange recorded over nine millimetres in the same space of time. The Cowra storm then struck the Blue Mountains, dropping hail the size of two-dollar coins. As the storm continued its eastward trek, it pummeled through Sydney. Small hail fell in far western parts of the city, but it was the dark shadow cast by the looming shelf cloud that started the social media storm. The rain came hard and fast, with Sydney Olympic Park collecting eight millimetres in ten minutes. Although many people watching the radar during this event were expecting hail to fall again in the city, the atmosphere was too moist and the thunderstorm itself was located a bit too high in the atmosphere. This rain wasn’t all bad news though - although many urbanites were complaining, our farmers were happy to get a dousing. Northern regions of the state, parts of which are in a severe 34 month rainfall deficiency, had widespread falls in excess of 15 mm yesterday and had additional thundery showers today. Tomorrow, showers and storms will still be present in NSW, but mostly along northern and southern parts of the coast, as well as adjacent inland areas. Fortunately, the end of the week looks to have a high pressure ridge develop, bringing a return to calm conditions throughout New South Wales.
