IPSWICH may have escaped most of the rain that has battered the state's north up to now, but a second trough could change things by as early as this Friday.
Innisfail, in far-north Queensland, received record July rain of 145mm on Monday night as a result of a low-pressure trough.
While the south-east only received a dribble by comparison, meteorologists have predicted that a second trough will blow in from the south west on Friday, delivering heavy rain.
The Weather Channel meteorologist Felim Hanniffy said Ipswich could expect rain periods on Friday and Saturday, followed by a cold snap.
"It looks like it is quite a strong system that is coming through," he said.
"It will bring cooler conditions in behind it - there will be a change back to cooler, drier weather."
Mr Hanniffy said Ipswich could see falls of up to 50mm on Friday.
The current forecast is for fine weather to return on Sunday, with overnight minimums to drop back into single figures and maximums to remain in the low 20s.
