Latest guidance is consistent with the forecast pattern and most
of the details over the coming seven days.  High pressure
northeast of the state this weekend should incrementally drift
westward, reaching a position more directly north of the islands
by next weekend.  A fairly tight gradient south of the high will
support brisk trades with somewhat higher wind speeds likely from
midweek through next weekend.  This pattern will support primarily
windward/mountain focus for showers but moisture may stray to
other locations at times.  An upper low tracking south of the
state this weekend into early next week, along with a band of
greater moisture crossing the area from east to west during
Tuesday-Wednesday, may help to enhance rainfall totals somewhat.
Guidance has been consistent so far in showing a drier pocket of
air passing through around Thursday followed by another area of
above-climatology moisture during at least a portion of the
Friday-Saturday time frame.
