IF you were considering packing away the brolly after two days of dry weather, the meteorologists have two words for you: think again.

The forecast for today and tomorrow is for thunderstorms and isolated showers, with the overcast outlook continuing into next week.

Weatherzone forecaster Doug Fenton said the trough, which had brought heavy rain and flooding to much of the western regions, would reach south-east Queensland today.

“We can expect falls of between 15 and 20mm, or more in the case of major storms,” Mr Fenton said.

“Locals should be prepared for the chance of flash flooding, with many dams and waterways across the Southern Downs region at capacity.”

He said maximum temperatures would be four to five degrees below the December average of 29C.

“We have had a cooler start to the summer under the cloud cover and that is likely to continue,” Mr Fenton said.

“We are expecting the wet weather to continue until Tuesday or Wednesday, with high levels of humidity increasing the chance of thunderstorms.”
