Weather Situation
A low pressure system is developing over the Bight and extends a warm front over Tasmania today, bringing a relatively warm and humid north to northwesterly airstream to the state. The low centre will approach from the west on Thursday with an associated cold front to cross later Friday. A much cooler south to southwesterly airstream is expected to follow the cold front, with more settled weather developing on Saturday as a high over the South Australian coast extends a ridge of high pressure over the state.
