BOM says southern Queensland forecast includes rain, hail and strong winds for this week

Wet days, strong winds and even hail are possible across southern Queensland this week as a low-pressure trough over central Australia moves east.

The trough is linked to a low-pressure system in the Great Australia Bight, which is set to bring wet weather to southern states.

The Bureau of Meteorology (BOM) is watching the system closely, saying it is expected to reach south-west Queensland by Wednesday.

BOM forecaster Helen Kirkup said there will be increasing upper levels of instability associated with the system.

"We may see some severity within these storms, so there is the possibility of large hail and very gusty winds and possibly heavy rains, that's not out of the question," Ms Kirkup said.

Residents of the Maranoa and Warrego district are urged to keep an eye on the weather warnings, with the BOM predicting severe weather conditions Wednesday.

Rain possible 'anywhere in the south-east'

The Maranoa and Warrego and Southern Downs can expect 30 to 40 millimetres of rain from Wednesday to Thursday ? and even more if storms develop.

"If thunderstorms do come across, we could easily see 60 millimetres or so in isolated locations from those," Ms Kirkup said.

"As we get across the granite belt and into south-east Queensland, Thursday and Friday are the main days, probably looking at maybe 20 to 30 millimetres across the two days and possibly more if some of those heavier showers or thunderstorms sort of pass by."

Ms Kirkup said the system will be broad and "anywhere in the south-east" could see rainfall on Thursday and Friday.

The BOM is also monitoring river levels near Goondiwindi on the southern border, with a potential for flood warnings for the Macintyre.

"There's very high soil moisture there and there was flooding there not that long ago, so I think they are going to keep a watch on how much rain might pass through those river catchments," Ms Kirkup said.

"It's pretty full and the catchments are pretty saturated, so that's something else to watch out for, potential for localised flooding or riverine flooding."

'High temperatures ahead of trough'

In the state's south-west, areas like Birdsville can expect temperatures to creep into the high 30s as the approaching trough brings northerly winds ahead of it.

But in the south-east, temperatures will stay around the low 20s until Thursday.

Ms Kirkup said the rest of the state will be largely cloud-free, with the northern inland region forecast to reach the mid to high 30s.

Fine by the weekend

Ms Kirkup urged people in southern Queensland to monitor the BOM's weather alerts this week.

"It's going to be a very interesting few days," she said.

She said the storms will be "one of the more decent storm outbreaks" of the year to date.

"A lot of it is focused south of the border, but that southern part of Queensland certainly is looking like it's included in with this system as it goes through," she said.

"As we get towards Saturday, any sort of thunderstorms, showers that are still around should be fairly confined just to the coast in the south and by Sunday, nearly the whole state is looking fairly clear for the end of the weekend."
