Notes on the Weather :
A weak cold front is crossing through Bass strait, a low pressure trough is inland. A moist onshore flow is evident in QLD, and a weak trough lies over the Top End. Over the next few days moisture is going to increase from the NT and QLD, and be forced into the interior of the country. This will activate the inland trough, and will move South.
On Wednesday a strong upper level trough will develop South of Perth and interact with this moisture as it moves East. Showers and Thunderstorms will become prevalent mid-week through SA and move into Vic late Wednesday. Another burst of cold air will follow late week for the southern states.
