MORE rain is likely for southern parts of Queensland starting on Friday, according to the Bureau of Meteorology.
BOM computer modeling for August 14 to 17 shows more reasonable rain for southern parts, particularly along the border almost as far as South Australia.
On Friday, BOM is forecasting an upper level system and associated surface trough are expected to enter the far west during Friday and progress eastwards during Saturday.
Showers and thunderstorms in the west, tending to rain areas across the south west and southern interior, are expected.
That system will spread eastwards across central and south eastern regions on Saturday.
BOM says at this stage, the rain is likely to clear off the east coast overnight Saturday or early Sunday morning.
Temperatures will trend cooler following the passage of the trough.
According to BOM the period to August 23 is likely to be wetter than average for much of Australia, although chances of a wetter or drier than average fortnight are close to equal across the far northern tropics.
Longer term, BOM says the September to November period is likely to be wetter than average across the eastern half of the mainland.
