Rain is on the way for the North West Slopes and Plains and the Northern Tablelands.
Meteorologist with weatherzone.com.au, Rob Sharpe, says the low pressure trough should bring some joy to farmers by Wednesday.
A broad low pressure trough and low pressure system are currently moving across Western Australia and into South Australia.
Rob Sharpe says the combination will bring moisture from the Indian Ocean.
He says the falls will be reasonable.
"For the North West Slopes and Plains approximately 10mm is going to fall across most of the region, with heavier falls most likely in the North West," he said.
"Then, into the Northern Tablelands, approximately 5mm to 10mm is expected across the board."
Rob Sharpe says the system will move out reasonably quickly on Thursday.
But he says a couple of extra troughs, associated with the east coast low, could bring a few more patches of rain closer to the weekend.
