Forecast issued at 5:01 am EST on Wednesday 19 June 2013.
A broad area of high pressure lies to the west of Tasmania, producing a light southerly flow over the state, and a weakening trough is expected to move over the southeast today. Overnight the high will move over the state, declining and moving away to the southeast on Thursday night whilst a low develops well to the west of Tasmania. During Friday the low will weaken over the Bight as a high pressure system to the south of WA extends a ridge to the south of the Bight. This high will approach Tasmania from the west during Saturday and the continuing influence of high pressure systems will make for light winds and cold nights into the weekend.
