Explanatory notes:

Fine conditions continuing through the weekend with the subtropical high pressure ridge to the south.Becoming warm with the west coast trough deepening near the west coast before the west coast trough moves inland by Monday bringing cooler conditions. Strengthening easterly gradient flow  limits the afternoon sea breeze and the strengthening easterly gradient combined with katabatic effect leads to strong easterly gusts over the hills and foothills tonight and early on Sunday with gusts exceeding 70 km/h possible.

Possible showers later next working week with a moist onshore flow with the possible formation of a cut off low over the south of the state ahead of an upper level trough but sill plenty of uncertainty this far out.
