Forecast issued at 5:15 am EDT on Wednesday 29 March 2017.
A low pressure system lies over central eastern Queensland and is gradually moving south-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 south of The Bight is approaching New South Wales. During Thursday, the cold front will bring a vigorous southerly change to southern and western districts, extending 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 on Thursday, with moderate to heavy falls likely. Heavy rain is most favourable in the northeast, assisted as the low approaches the far northeast of New South Wales later Thursday or Friday. 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.
Forecast for the rest of Wednesday
