Weather Situation

A deep low pressure system south of Kangaroo Island is moving eastwards to be over the South East districts late Wednesday evening. An associated cold pool of air will accompany the low, bringing unseasonally colder conditions throughout. The low will then move over Victoria overnight to be centred just east of Tasmania by later Thursday, and a high pressure system will develop well southwest of the Bight, extending a ridge over the west and north of the State. This high will move slowly eastwards on Friday, ahead of another low pressure system developing near the western border during Saturday morning then moving eastwards across the Bight during the day, before weakening and moving over central South Australia on Sunday.
