A big subtropical high, both at the surface and aloft, will remain
anchored in place north of the state, with the center of the high
near 35-40 degrees north through Thursday night.  The strong
pressure gradient in place will maintain windy conditions with
flow from generally the east-northeast through the end of the
week, with winds gusting over 35 mph at times, along with very
rough surf.  Some abatement in the winds is likely going into the
weekend as an inverted trough and potential surface low forms east
of the state, and this low will likely lift north near 145 degrees
west.  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.
