Latest guidance remains in good agreement of a high pressure
system passing to the north and east of the islands through the
weekend into Monday.  The cold front that has already passed to
the south of the islands has become stationary.  Showers
associated with the front should generally be south of the Big
Island.  However, as the high moves farther to the east and
surface winds turn more southerly, increasing moisture is expected
to return by Sunday into Monday with an increasing chance of
showers over the Big Island. As we get into midweek next week,
models are in good agreement that a cold front will arrive with a
band of heavier showers moving across from west to east from
Wednesday to Thursday.  While previous runs of ECMWF have
indicated a sharper and deeper upper trough associated with this
front, it has trended quicker with the system's ejection to the
northeast in agreement with most of the other current guidance.
