A large mid-latitude surface high will be north of the state and
move eastward along 45N through Sunday before settling some to the
south.  Aloft, a pattern almost resembling an omega block will
likely be in place across the North Pacific through the weekend,
with a trough axis situated well to the northeast of the state. 

In terms of sensible weather, a typical trade wind pattern should
prevail for much of the forecast period.  Easterly flow of 15-25
mph with higher gusts will be likely through Thursday, and then
backing slightly to the east-northeast beyond that as the strong
surface high builds in to the north, and the trades perhaps
becoming slightly stronger.  The greatest coverage of showers are
expected across the windward terrain of the Big Island, and some
heavier showers are possible by early next weekend with a slight
increase in lower tropospheric moisture.
