Guidance seems reasonable clustered and indicated that surface 
high now centered to the norteast of the state should weaken and 
drift southeastward, allowing for island winds to gradually lessen
to more moderate levels by Saturday. It also seems evident that winds
may raise to more breezy levels into next week as a series of 
high pressure cells bridge to the north of the state. Meanwhile, 
an upper trough is forecast to gradually approach from the west 
with some lowering heights over Hawaii. This plus a front stalling
to the north and west will draw higher moisture northward across 
the state as mean flow turns more southeasterly. Thus, shower 
coverage and higher rain totals are more likely over the weekend 
into early next week over the islands, but there could be a 
particular focus over the western islands closer to the 
front and deeper moisture. More typical trade winds may return 
around midweek while moisture levels gradually fall as the trough 
loses influence.
