The rainband that crossed Victoria yesterday moved slowly northeast into NSW today, with thunderstorms forming ahead of its leading edge. 20 to 50mm of rain fell on the South Coast between midmorning and late afternoon. In the cloudfree zone ahead of the rainband, temperatures and humidity levels rose in a zone of high instability, leading to the development of a broad area of storms in the Central Tablelands which propagated eastwards before moving ESE across the coast near Sydney during the evening. The satellite image (left) shows this mesoscale convective system at 11pm as the large area of yellow to red. The smudge of orange to its southwest is the beginning of a second area of storms that crossed the Illawarra coast during the early morning. While there were scattered areas of heavy rain, the most notable feature of these systems was the electrical activity, providing a spectacular lightning and thunder show across the Central Tablelands and along the coast from the Hunter Valley to the Illawarra well into Wednesday morning.
