Forecast issued at 5:15 am EDT on Thursday 30 March 2017.
A low pressure system lies over central eastern Queensland and is gradually moving southeast, while high pressure system over the Tasman Sea helps drag humid tropical air to northeastern New South Wales. At the same time a cold front over the far south and west of the state is moving east. This cold front will bring a vigorous southerly change to southern and western districts today, and to the northeast on Friday. The interaction between this front and the humid airmass from the north is forecast to generate widespread rain across eastern districts today, with moderate to heavy falls likely. Heavy rain is expected in northeast, due to the approaching low pressure system. Conditions are expected to ease later Friday as the front and low move away to the east, although a new high developing south of the Bight will bring follow-up showers to eastern areas.
