Weather Situation
A cold front crossing the eastern parts of SA will continue moving eastwards and cross the rest of the state early today. A ridge of high pressure will then push into SA from the west today, with the associated high moving over SA on Thursday. The high then gradually drifts southwards to be located in vicinity of Tasmania over the weekend, as it continues extending a ridge across SA.
