A big subtropical high, both at the surface and aloft, will remain
near 35-40 degrees north through the remainder of the week.  The
strong pressure gradient in place will maintain windy conditions
with flow from generally the east-northeast through Friday, with
winds gusting 30-40 mph at times, along with very rough surf.  The
trades are forecast to abate going into the weekend as the
influence of the high lifts north and an inverted trough and
surface low forms east of the state, and this low will likely stay
east of the Big Island.  Even lighter winds are possible going
into Monday with a col developing over the region.

The potential for moderate to heavy showers across the windward
terrain, particularly across the Big Island, will exist through
much of the week with several inches of rainfall possible.  This
may be enough to cause some flooding concerns for flood-prone
areas.  Some improvement is likely going into Sunday and next
Monday.
