As the upper low that has been affecting the state in recent days
continues to depart to the southwest, expect an extended period of
trades and primarily windward/mountain-focused showers to last
through at least next Thursday.  High pressure over the eastern
Pacific and a surface trough to the west of the main islands will
likely support moderate to brisk trades from the east-southeast
into the weekend.  Winds should turn more easterly late weekend
into early next week as the trough weakens.  Then during Tue-Thu
high pressure tracking over the east-central Pacific may support
somewhat stronger trades from the east-northeast.  A band of
enhanced deep moisture crossing the area from east to west on
Thu-Fri could increase rainfall amounts somewhat, followed by a
drier trend as precipitable water values drop to around one inch
for most of next week.  Recent model trends showing the upper
ridge initially northwest of the area drifting close to or over
the state may also serve to limit shower activity during the
early-mid week time frame.
