An unstable airmass and low pressure are bringing scattered showers and storms to WA's northern half, the NT, tropical northern Qld, and inland SA. Moist onshore winds are bringing isolated storms across eastern Qld.

Becoming warmer over Vic, Tas and NSW in NE'ly winds ahead of a trough and cool change crossing SA. A broad area of instability, storms and heat will deepen over the NT and northeast WA, with another area also developing over Qld. Gusty and warming E'ly winds for southern WA.

A stormy trough & cool change will move across NSW to southern Qld. Cool for Tas, Vic & southern SA. Gusty E'ly winds persisting over southern WA with some showers/storms developing. Storms also in an arc from northern WA across the NT to southeast Qld, with heat in the far north

Some gusty storms are likely to persist in eastern NSW and over Qld near a low pressure area. Storms again for the NT and at least eastern WA in a broad area of instability and heat. Hot also for the northern NT and Qld. Cooler across the south in southerly component winds.

Twin low pressure troughs extending over southern WA and Qld-NSW from a broad low pressure area over the north will generate heat, showers and storms. Cooler, more stable and mostly dry across southern areas, including eastern SA, Vic and Tas, in southerly component winds.

A broad low pressure trough extending over southern WA and Qld-NSW may continue to generate heat, showers and possibly severe storms. Cooler across southern areas in southerly component winds. A showery, gusty cold front could affect Tas and Vic.

A broad low pressure trough extending from northern WA to Qld and NSW may continue to generate heat, showers and possibly severe storms, leading to heavy rainfall. Mostly dry and/or stable across southern regions under a high-pressure ridge over SA, Tas and Vic.
