Today's models and ensembles maintain good agreement on a typical
trade wind pattern with light windward focused showers through the
period.  Strongest trades should be at the start of the period
Wed-Thu as a surface high passes to the north of the state. 
Another high will be weakening as it reaches 170-160W longitude by
Sat and likely have minimal impact on trades.  By next week the
strongest surface ridging will be over the eastern Pacific,
placing the islands in the mere periphery of its influence.  The
relatively light rainfall in the forecast is consistent with below
average precipitable water values, within a tenth or two of one
inch at most times, and a mid level ridge along 20N latitude.  By
the latter half of the period guidance continues to show this
ridge gradually strengthening and eventually closing off a high to
the northeast of the islands.
