Sydney's suburbs received a drenching yesterday afternoon as a band of thunderstorms flashed past. A deep low pressure trough made its way over eastern parts of the state yesterday stimulating widespread showers and thunderstorms which made the radar light up like a Christmas tree. With the initial band of fast moving thunderstorms, reports were made of small hail about Wahroonga, Carlingford and Parramatta along with heavy showers. Kings Langley picked up the heaviest 24 hour total to 9am today with 25mm falling in the rain gauge. Nearer to the coast, Terrey Hills received a short deluge with 6.4 millimetres falling within just ten minutes. Across the Sydney Basin during the time of the storms, 275 lightning strikes were recorded within a 30 kilometre radius of Baulkham Hills. As the region of low pressure moved offshore overnight, a southerly flow has now taken its place. These moist winds moving along the Sydney coast present the chance of the odd isolated shower, although as the day progresses conditions should improve.
