Forecast issued at 10:00 pm EDT on Wednesday 7 December 2016.
A high over eastern New South Wales and a cold front over and south of the Bight are combining to produce a northerly stream over Tasmania. The stream will strengthen tomorrow before the front crosses Tasmania during the morning, and the associated low deepens as it nears the southwest coast. Strong and gusty northwesterly winds will precede a secondary front in the afternoon, followed by a cooler southwesterly change in the evening. This will gradually ease on Friday as a high moves into the Bight, then moves slowly eastwards on Saturday. The high will move over Tasmania on Sunday bringing mostly settled conditions and light winds.
