A moist, unstable airmass generates showers and storms over the northern tropics (including Darwin) and central and inland WA. High pressure brings a few showers to south coast WA and keeps much of Australia's south dry. An approaching front brings showers to Tas and coastal Vic.

Showers will move across Vic & Tas and build along coastal NSW & Qld with a front. Moist heatwave conditions over the northern tropics will provide thunderstorms. A trough will bring thunderstorms to inland WA & the central interior, some intense.

Moisture and heat should bring thunderstorms over the northern tropics, extending into southern NT, and inland SA with low pressure. S'ly moist onshore winds bring few showers for coastal WA, Vic, NSW and Qld. Dry over eastern inland areas under a high pressure ridge.

Moisture and heat should bring storms across the northern tropics, extending into eastern WA, across the NT, and inland SA with low pressure. Onshore winds bring showers to coastal Qld. S'ly winds with high pressure bring showers to WA and SA's south.

Moisture and heat may bring storms across the northern tropics, extending into eastern WA, southern NT, QLD, northern SA and NSW with low pressure and troughs. Onshore winds may bring showers to Vic and Tas. High pressure could keep WA and SA coasts generally dry.

Moisture and heat could bring storms across the northern tropics, extending across WA, the NT, and inland and coastal QLD with broad low pressure and troughs. A front may bring showers to NSW, while conditions may clear across Vic and Tas, with SA mostly dry under high pressure.

Moisture and heat could bring storms across the northern tropics, across eastern WA, the NT, and inland QLD with broad low pressure and troughs. Moist onshore winds may bring showers to NSW and Qld. High pressure may clear conditions across eastern SA, inland NSW, Vic and Tas.
