Sunday - Latest

Low pressure troughs extending across WA, the NT and into central QLD are triggering the showers and storms, heaviest over northern WA. A weak trough is producing the odd shower for TAS. High pressure across central Australia is keeping elsewhere mostly dry.


Monday 22:00 EDT

A front will bring a burst of brisk winds and showers to TAS, southern SA and VIC. An associated trough will generate heat and thunder in VIC, southern and western NSW and western QLD. Other troughs will trigger storms in the northern tropics and a few over a heating inland WA.


Tuesday 22:00 EDT

Troughs will generate showers and storms across the northern tropics, inland WA and NSW and maintain heat over the interior. Weak fronts will cool parts of NSW and southwest WA with help from showers. Tropical Cyclone Oma should cause waves to become large on the south QLD coast.


Wednesday 22:00 EDT

Troughs will generate showers and storms across the northern tropics, inland WA and maintain heat over the interior. Weak fronts will cool parts of the far south of the country with help from showers. Tropical Cyclone Oma should cause waves to become larger on the south QLD coast


Thursday 22:00 EDT

Decaying Tropical Cyclone Oma should cause large waves on the south QLD and northern NSW coasts. Troughs will maintain heat and a few storms in the northern tropics and interior. A front will cool parts of the southeast of the country with help from showers, mainly TAS.


Friday 22:00 EDT

A low pressure system in the Tasman and trough in the east should bring showers and thunderstorms to QLD and NSW, with gusty showers and powerful surf expected along the coast. Troughs extending over northern NT and into central WA should bring hot conditions and isolated storms.


Saturday 22:00 EDT

Troughs extending into central WA, across the northern NT and into southern QLD will bring showers and thunderstorms. A high pressure system should direct gusty showers to coastal NSW and QLD. High pressure should keep elsewhere dry and generally clear.
