A trough is generating warm, humid weather and heavy rain and storms across QLD, NSW and eastern VIC. A deep low near TAS is sending cooler, gusty winds and showers over TAS, western VIC and SA. Tropical Cyclone Iggy, well off the northwest WA coast, is triggering squally rain.
The northern jetstream is feeding moisture into a trough in the east. The southern jetstream is arcing over the southeast of the country, allowing a front and colder air to surge into the region.

A trough will trigger rain and storms through NSW and QLD, locally heavy. A front will spread a cooler, showery change through southeast Australia. A high will clear SA, while sending dry and fresh winds into WA. Tropical Cyclone Iggy will remain off the northwest coast.

Moist easterly winds will continue to feed into troughs over eastern Australia, triggering heavy rain and storms. Cool winds will maintain showers along the nation's southeast coast. Tropical Cyclone Iggy should weaken off the WA coast, but may direct rain onto the west coast.

The remnants of Tropical Cyclone Iggy may linger near the west coast, generating shower over southwestern parts of WA. Troughs in the east will trigger areas of heavy rain through QLD, NSW and VIC. The monsoon trough will generate heavy storms across the northern tropics.

A trough stretching through QLD, NSW and eastern VIC should weaken, allowing rain and storm activity to ease. A front and trough should bring a cooler change to southwest WA as a low generates rain in the region. The monsoon trough will trigger scattered storms in the tropics.

A front and trough should spread a cooler, showery and windy change through southern Australia. Another trough may trigger scattered showers and thunderstorms in NSW and QLD. A developing low may generate heavy rain over the northeast tropics.

A front should spread a cooler, showery change through southeast Australia. A trough stretching through NSW and QLD may trigger scattered showers and thunderstorms. A high pressure ridge will clear southern parts of the nation, while directing warm, dry and fresh winds into WA.
