Forecast issued at 4:32 pm EDT on Monday 22 December 2014.

Weather Situation

A high pressure system over the Tasman Sea is drifting slowly east, while a broad trough lies near the western border of New South Wales. The deepening of this trough during the next day or two, assisted by an influx of warm and humid tropical air, is expected to bring a period of unsettled weather which will affect most districts. It is likely that the trough will become more mobile during the second half of the week, shifting towards the northeast in response to an approaching upper-level system.
