Surface high pressure meandering well north of the state will
settle to the north-northwest of the area during Tuesday-Saturday.
 Following the passage of a weakening surface trough and upper
level feature this weekend, expect trades to be on the brisk side
during the first half of next week.  By late week into next
weekend most guidance suggests that the surface gradient and trade
flow should weaken somewhat though not quite to the extent
suggested by the 00z GFS.

The combination of above normal precipitable water values and an
upper level weakness passing over the state this weekend may
support some locally enhanced rainfall.  Then for most of the
coming week shower activity should be on the lighter side as
precipitable water decreases to near or somewhat below normal
levels.  Another upper level weakness may pass through the area
around Friday and promote a slight increase in showers.  Rainfall
will likely favor windward terrain but could stray to other
locations at times.
