PARTS of western Queensland can expect falls of up to 100mm in the next four days according to Bureau of Meteorology modelling.



BoM says a slow-moving surface trough will remain over south east and central Queensland for the next few days, with scattered showers and thunderstorms to its north early this evening and again on Monday afternoon.



However, south of the trough are southerly winds and warm, dry air.



BoM's predicted rain for Tuesday.

"The movement and development of the upper trough will determine where the best rainfall totals are, with a focus south of about Longreach and north of about Quilpie and Charleville," BoM says.



According to BoM, the upper trough will stall over western Queensland on Wednesday. The surface trough brings more moisture westwards, with showers, patchy rain and storms continuing through parts of the central interior and south west.

Elsewhere, the ridge of high pressure will persist along the east coast, bringing isolated light showers ashore north of about Gladstone.

On Thursday the upper trough will remain slow moving, with showers, isolated storms and patchy rain likely to continue in parts of the central and southern interior.

BoM modelling shows a new upper trough will develop over the Northern Territory and moves eastwards over the weekend.



However, BoM says there is considerable uncertainty with the development and movement of this feature, but says it may lead to showers and storms about western and southern parts.
