Forecast issued at 4:31 pm EST on Monday 1 September 2014.
A trough and cold front is moving through southwest New South Wales, and is expected to move through the coast on Tuesday. A high pressure system to the west of the Bight is expected to extend a ridge into western New South Wales behind the front. When the trough and frontal system move over the western Tasman Sea, cool upper air in the atmosphere will promote the development of a low pressure system.
