Moisture will increase across the region as a cutoff low weakens 
and drifts westward north of the state. This will boost daily
shower activity, allowing for areas of locally heavy rainfall.
Early next week the easterly trades are expected to return as 
upper riding and surface high pressure rebuilds to the north.
