Models and ensembles continue to show similar ideas in the
forecast through the next seven days.  With some day to day
variation, trades will be fairly strong through the period as one
surface high well to the northwest of the state is replaced by a
second high around Saturday, with the latter high ultimately
tracking to the north and northeast of the area. 
Windward/mountain-focused showers (occasionally extending into
other areas) should be on the lighter side through Thursday as
precipitable water values remain below climatology.  From Friday
into the weekend the combination of a surface front and shortwave
energy aloft settling over the region from the north should lead
to higher rainfall totals.  Although the upper trough gradually
fills early next week, most guidance is suggesting a further
increase of moisture from the south or southeast.  This would
favor some rainfall enhancement over the eastern islands at that
time.
