Troughs over eastern parts of QLD and NSW are triggering heavy showers and thunderstorms, some severe. Troughs over parts of WA and the NT are also causing showers and thunderstorms. High pressure is keeping conditions settled over SA, ACT, VIC and TAS.


Saturday 22:00 EDT

Onshore flow and a nearby trough and low should maintain rain and storms across eastern parts of QLD and NSW, some heavy.  Another linked trough will bring a few showers to VIC and southeast NSW. Lows embedded in a broad trough will cause showers and storms to WA and the NT.


Sunday 22:00 EDT

A coastal trough will weaken, easing showers over east QLD and NSW.  Another trough should deepen over the inland east, bringing increasing showers/rain/storms to VIC, southern NSW and southeast SA.  Dry with a high over much of SA and WA. Storms near a trough over the tropics.


Monday 22:00 EDT

Trough and a low pressure system over the southeast should bring rain to southern NSW, VIC and TAS. Onshore feeding a trough should weaken, easing showers and storms across east QLD and northeast NSW. A broad trough should cause storms across WA and the NT.


Tuesday 22:00 EDT

Warmer and drier over NSW, VIC and southeast SA as winds turn westerly ahead of a front. Troughs will maintain a few showers in the far east, mainly near the NSW/QLD border. A trough will continue to bring storms to WA and the NT while helping drive heat over interior.


Wednesday 22:00 EDT

Low pressure troughs in the north and east will trigger areas of showers and storms, some intense, whilst directing heat and high humidity across the southeast. Fronts in the south should eventually introduce cooler and less humid air into southern WA, SA, VIC and TAS.


Thursday 22:00 EDT

A front and trough will move northeast, bringing a cooler day to southeast SA, VIC and southern NSW. Showers and storms re-intensifying ahead of the trough over QLD. A high will bring dry and warm winds to southern WA and much of SA. Storms persisting with lows across the north.
