Forecast issued at 10:00 pm EDT on Thursday 13 December 2018.

Weather Situation

An intense and broad area of low pressure lies over southeastern Australia with an associated trough extending northwards over the mainland and southwards over western Tasmania. A ridge of high pressure lies to the south of this, linked to highs over the Bight and near New Zealand. A moist easterly flow over Tasmania will continue as the low weakens on Friday and moves over New South Wales then southwards over the weekend. This will extend a rain band over Tasmania on Saturday, with locally heavy falls about the north, and rain will continue on Sunday as the low moves south of the state. A westerly change is forecast during the afternoon, with the stream tending southerly on Monday as the low moves away to the southeast.
