Forecast issued at 5:15 am EDT on Wednesday 18 January 2017.
A high is over the Tasman Sea and a trough is located over central New South Wales, directing a hot northerly airstream over the state. This trough is forecast to move north in response to a cold front slipping south of the state, bringing a milder southerly change to western and southern districts. The change should move through the remainder of the state on Thursday, although high temperatures will remain over the northwest. Following the change, another high pressure system will move across southern Australian and over the Bight, before the next trough is expected on Friday.
