Low pressure troughs and unstable air masses are generating widely scattered showers and thunderstorms across the northern half of WA, the NT, Qld and northeast NSW. Bands of rain with troughs have moved from SA to NSW and Vic. Dry over much of WA's southeast in high pressure.

A broad trough across the north and east will intensify, leading to a very warm day with rain and intense storms across the NT, Qld and NSW. A front will bring cooler, blustery winds and showers to SA, Vic and Tas. Showers and storms for WA as a trough develops over the state.

Showers and storms, some intense, for northeast WA, the NT Top End, Qld and NSW in active troughs. Another trough will trigger showers and storms over WA’s south. A cold front will bring gusty winds and showers to Tas, Vic and southeast NSW. Dry over SA with high pressure.

Troughs could trigger showers and storms, some intense, over WA, SA’s northwest, the NT, and Qld’s north and east. A cold front may trigger showers and storms over eastern NSW and gusty showers over Vic and Tas. Dry, settled and mostly clear for SA with a high pressure ridge.

A broad trough could trigger showers and storms, some intense, across WA and the NT Top End. Another trough and a cold front in the east may trigger a few showers and storms over far eastern Qld and far eastern NSW. Generally dry elsewhere with high pressure.

A broad trough could trigger showers and storms, some intense, across WA, the NT and western SA. A broad high pressure ridge in the east will keep much of SA, Vic and Tas dry while clearing showers over NSW. Showery onshore winds for eastern Qld.

A broad trough of low pressure should generate showers and thunderstorms across eastern WA as well as parts of the NT and SA. A high over the Tasman Sea should direct showers across coastal NSW and Qld. High pressure should keep the eastern interior dry.
