Weather for the weekend of 6 -7 August 2011

Updated 5/8/2011

A high off the northern NSW coast is moving slowly east. A trough behind the high is forecast to spawn a low at its southern tip on the southern NSW coast. The trough is very active, with rain falling from central SA through to Tasmania, but its northern tip is only at the latitude of the Queensland border and does not appear to be extending north.

NOAA is now forecasting no rain on Saturday and only 2mm on Sunday. It is possible that the northern activity tip will be south of the Downs by Sunday.

The low that will form is shallow and not forecast to deepen and thus the southerly winds in Queensland will remain light.

There has been no rain on the Downs in the last seven days.
