High pressure is expected to settle over the eastern Pacific this
weekend and persist through at least the middle of next week
leading to a fairly typical trade wind pattern with occasional
periods of more moderate to breezy speeds. This should bring
mainly light showers to the favorable eastward facing slopes.
Models suggest an upper trough may cross the region around Friday
into Saturday, with some decent moisture moving in over Hawaii and
potential for more widespread and heavier showers across portions
of the state. The 00z GFS is fastest/farthest south pointing
towards better moisture across the Big Island, while the ECMWF
brings the better moisture into the northern islands. Plenty of
details to be worked out, so a blend towards the ensemble means
seems best at this time.
