Model and ensemble solutions seem reasonably well clustered for  
the next week and a composite offers a good forecast basis with
good predictability. A main surface high centering well to the 
northeast of the state will favor seasonal island trades this 
weekend and early-mid next week. The high should build and bridge
to the north of the state later next week to produce an uptick in
trades/breezy flow. This pattern will focus limited moisture amd 
rainfall into windward terrain, with remaining areas of state in a
relatively tranquil weather pattern under ridging aloft.
