AFTER stormy conditions last week, residents across the Southern Downs hoping for a reprieve can expect a week of possible showers and storms before a sunny weekend.

Weatherzone meteorologist Rob Sharpe said the Southern Downs could expect today to be mostly sunny with a high of 31 degrees for Warwick.

"There is a trough moving through the Darling Downs region which is expected to deepen tomorrow, with rain areas and a risk of thunderstorms," Mr Sharpe said.

The maximum for Warwick on Wednesday is expected to be 26 degrees with cloud cover affecting temperatures.

"There is a good chance of farmers across the region seeing rain on Wednesday, with it being the wettest day of the week," Mr Sharpe said.

Mr Sharpe described Thursday as a classic thunderstorm day.

"The trough will linger into Thursday with less chance of rain but a high chance of thunderstorms across the region," he said.

"Thursday is expected to see a maximum of 24 degrees."

Friday is set to be drier and cooler than early in the week, with a maximum of 26 degrees and chance of a shower or two.

Mr Sharpe said the weekend is expected to be sunny with maximums of 28 degrees and 29 degrees for Saturday and Sunday.

As for the weather forecast for Santa's impending arrival, Mr Sharpe said it is expected to be a fairly typical Christmas day for the Darling Downs.

"Models can change as we are still several days out, but at this stage it is expected to be fairly warm with temperatures in the high-20s," Mr Sharpe said.

"There is likely to be a high risk of afternoon showers or thunderstorms across the region."
