Forecast issued at 5:16 am EDT on Thursday 23 October 2014.
A high pressure system over the central Tasman Sea extends a ridge towards the Queensland coast, while a broad trough of low pressure lies across southern and western New South Wales. There will be only subtle changes to this pattern over the next day or two, before the trough becomes more mobile on the weekend and shifts to the northeast under the influence of a Southern Ocean front. During this time many eastern districts are likely to see unsettled weather, while the west remains in the grip of a persistent hot airmass. Another trough and associated cold front appear likely to affect the state early in the new week, bringing somewhat cooler conditions.
