A high just east of Tasmania is moving slowly east and ridging up the east coast. This high will dominate through the weekend, bringing a fairly strong easterly flow with associated coastal showers. It is possible that one or two showers may cross the divide on to the Downs, particularly on Sunday. Sunday will also see high cloud about, which may, at times, be thick enough to shade the ground.
There has been some heavy rain on the Downs in the last seven days (principally last Saturday). This brought falls between 30 - 50 mm across the Downs, with 40mm falling at Oakey and 43mm at Roma. As this rain will be 7 days or more in the past by the weekend, the ground should have mostly dried out. However, there will be wet areas along creeks and in low lying areas that will remain unlandable and could suppress convection locally.
