Forecast issued at 5:15 am EST on Thursday 1 September 2016.
A cold front and associated rain band have crossed New South Wales and moved over the Tasman Sea, leaving a weak high pressure ridge across the state in their wake. A new low pressure trough is expected to develop over southwest Queensland during Thursday, deepening into a low pressure system as it shifts into New South Wales on Friday. This next system is forecast to bring widespread rain to the state, with some areas receiving moderate to heavy falls. On the weekend the low should move fairly rapidly away to the east, with a ridge in its wake restoring mostly fine conditions over southeast Australia.

Partly cloudy. Areas of fog early this morning. High (80%) chance of rain about the Upper Hunter, most likely this afternoon and evening. Medium (50%) chance of showers elsewhere. Light winds. Daytime maximum temperatures between 19 and 23.
