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 night,
with winds gusting 30-40 mph at times.  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
Saturday with several inches of rainfall possible.  Some
improvement is likely going into Sunday and next Monday.  A cold
front may approach the state from the northwest by the middle of
next week and bring a round of additional showers and storms.
