A large mid-latitude surface high will be building in north of the
state through the weekend and then settling some to the southeast.
 At the surface, a weakening cold front trailing from the surface
low between Hawaii and California will likely approach the
northern Islands this weekend before gradually dissipating. 

In terms of sensible weather, light to moderate easterly trades
should prevail through Saturday, and then becoming stronger by
early next week as the pressure gradient intensifies from the
strong high to the north.  The GEFS and EC means are in good
overall agreement on this pattern developing.  The greatest
coverage of showers are expected across the windward terrain of
the Big Island, but there are not any organized storm systems on
the horizon for Hawaii over the next seven days with the deep
tropical moisture remaining south of the state.
