The weakening of surface high pressure centered to the northeast 
of the state favors more moderate island winds today. However, guidance
also indicates that winds should raise to more breezy levels later
weekend into next week as another in a series of high pressure 
cells bridge to the north of the state. Meanwhile, an upper trough
is forecast to gradually settle from the west with some lowering 
heights over Hawaii. This plus a front stalling just to the north 
and west of the islands will act to draw moisture across the 
state. Thus, shower coverage and some higher rain totals are more
likely over the weekend into early next week. More typical trade 
winds may return around midweek while moisture levels gradually 
fall as the trough loses influence.
