- Weather Situation
- A high pressure centre lies near the South Australian coast today and tomorrow, directing a cold southwesterly airstream over the state. The high is expected to move to the north of Tasmania later Monday, extending a ridge over the state as it passes. A cold front approaches from the west on Tuesday and is expected to cross later in the day with a westerly airstream to follow. The airstream then tends northwesterly early Thursday as a more significant cold front approaches from the west, crossing later in the day. A cold and gusty southwesterly stream will then follow.
